Critical thinking is the ability to effectively analyze information and form a judgment .

To think critically, you must be aware of your own biases and assumptions when encountering information, and apply consistent standards when evaluating sources .

Critical thinking skills help you to:

• Identify credible sources
• Evaluate and respond to arguments
• Assess alternative viewpoints
• Test hypotheses against relevant criteria

Critical thinking is important for making judgments about sources of information and forming your own arguments. It emphasizes a rational, objective, and self-aware approach that can help you to identify credible sources and strengthen your conclusions.

Critical thinking is important in all disciplines and throughout all stages of the research process . The types of evidence used in the sciences and in the humanities may differ, but critical thinking skills are relevant to both.

In academic writing , critical thinking can help you to determine whether a source:

• Is free from research bias
• Provides evidence to support its research findings
• Considers alternative viewpoints

Outside of academia, critical thinking goes hand in hand with information literacy to help you form opinions rationally and engage independently and critically with popular media.

Critical thinking can help you to identify reliable sources of information that you can cite in your research paper . It can also guide your own research methods and inform your own arguments.

Outside of academia, critical thinking can help you to be aware of both your own and others’ biases and assumptions.

Academic examples

However, when you compare the findings of the study with other current research, you determine that the results seem improbable. You analyze the paper again, consulting the sources it cites.

You notice that the research was funded by the pharmaceutical company that created the treatment. Because of this, you view its results skeptically and determine that more independent research is necessary to confirm or refute them. Example: Poor critical thinking in an academic context You’re researching a paper on the impact wireless technology has had on developing countries that previously did not have large-scale communications infrastructure. You read an article that seems to confirm your hypothesis: the impact is mainly positive. Rather than evaluating the research methodology, you accept the findings uncritically.

Nonacademic examples

However, you decide to compare this review article with consumer reviews on a different site. You find that these reviews are not as positive. Some customers have had problems installing the alarm, and some have noted that it activates for no apparent reason.

You revisit the original review article. You notice that the words “sponsored content” appear in small print under the article title. Based on this, you conclude that the review is advertising and is therefore not an unbiased source. Example: Poor critical thinking in a nonacademic context You support a candidate in an upcoming election. You visit an online news site affiliated with their political party and read an article that criticizes their opponent. The article claims that the opponent is inexperienced in politics. You accept this without evidence, because it fits your preconceptions about the opponent.

There is no single way to think critically. How you engage with information will depend on the type of source you’re using and the information you need.

However, you can engage with sources in a systematic and critical way by asking certain questions when you encounter information. Like the CRAAP test , these questions focus on the currency , relevance , authority , accuracy , and purpose of a source of information.

When encountering information, ask:

• Who is the author? Are they an expert in their field?
• What do they say? Is their argument clear? Can you summarize it?
• When did they say this? Is the source current?
• Where is the information published? Is it an academic article? Is it peer-reviewed ?
• Why did the author publish it? What is their motivation?
• How do they make their argument? Is it backed up by evidence? Does it rely on opinion, speculation, or appeals to emotion ? Do they address alternative arguments?

Critical thinking also involves being aware of your own biases, not only those of others. When you make an argument or draw your own conclusions, you can ask similar questions about your own writing:

• Am I only considering evidence that supports my preconceptions?
• Is my argument expressed clearly and backed up with credible sources?
• Would I be convinced by this argument coming from someone else?

Critical thinking refers to the ability to evaluate information and to be aware of biases or assumptions, including your own.

Like information literacy , it involves evaluating arguments, identifying and solving problems in an objective and systematic way, and clearly communicating your ideas.

Critical thinking skills include the ability to:

You can assess information and arguments critically by asking certain questions about the source. You can use the CRAAP test , focusing on the currency , relevance , authority , accuracy , and purpose of a source of information.

Ask questions such as:

• Who is the author? Are they an expert?
• How do they make their argument? Is it backed up by evidence?

A credible source should pass the CRAAP test  and follow these guidelines:

• The information should be up to date and current.
• The author and publication should be a trusted authority on the subject you are researching.
• The sources the author cited should be easy to find, clear, and unbiased.
• For a web source, the URL and layout should signify that it is trustworthy.

Information literacy refers to a broad range of skills, including the ability to find, evaluate, and use sources of information effectively.

Being information literate means that you:

• Know how to find credible sources
• Use relevant sources to inform your research
• Understand what constitutes plagiarism
• Know how to cite your sources correctly

Confirmation bias is the tendency to search, interpret, and recall information in a way that aligns with our pre-existing values, opinions, or beliefs. It refers to the ability to recollect information best when it amplifies what we already believe. Relatedly, we tend to forget information that contradicts our opinions.

Although selective recall is a component of confirmation bias, it should not be confused with recall bias.

On the other hand, recall bias refers to the differences in the ability between study participants to recall past events when self-reporting is used. This difference in accuracy or completeness of recollection is not related to beliefs or opinions. Rather, recall bias relates to other factors, such as the length of the recall period, age, and the characteristics of the disease under investigation.

Critical Thinking

Critical thinking is a widely accepted educational goal. Its definition is contested, but the competing definitions can be understood as differing conceptions of the same basic concept: careful thinking directed to a goal. Conceptions differ with respect to the scope of such thinking, the type of goal, the criteria and norms for thinking carefully, and the thinking components on which they focus. Its adoption as an educational goal has been recommended on the basis of respect for students’ autonomy and preparing students for success in life and for democratic citizenship. “Critical thinkers” have the dispositions and abilities that lead them to think critically when appropriate. The abilities can be identified directly; the dispositions indirectly, by considering what factors contribute to or impede exercise of the abilities. Standardized tests have been developed to assess the degree to which a person possesses such dispositions and abilities. Educational intervention has been shown experimentally to improve them, particularly when it includes dialogue, anchored instruction, and mentoring. Controversies have arisen over the generalizability of critical thinking across domains, over alleged bias in critical thinking theories and instruction, and over the relationship of critical thinking to other types of thinking.

Use of the term ‘critical thinking’ to describe an educational goal goes back to the American philosopher John Dewey (1910), who more commonly called it ‘reflective thinking’. He defined it as

active, persistent and careful consideration of any belief or supposed form of knowledge in the light of the grounds that support it, and the further conclusions to which it tends. (Dewey 1910: 6; 1933: 9)

and identified a habit of such consideration with a scientific attitude of mind. His lengthy quotations of Francis Bacon, John Locke, and John Stuart Mill indicate that he was not the first person to propose development of a scientific attitude of mind as an educational goal.

In the 1930s, many of the schools that participated in the Eight-Year Study of the Progressive Education Association (Aikin 1942) adopted critical thinking as an educational goal, for whose achievement the study’s Evaluation Staff developed tests (Smith, Tyler, & Evaluation Staff 1942). Glaser (1941) showed experimentally that it was possible to improve the critical thinking of high school students. Bloom’s influential taxonomy of cognitive educational objectives (Bloom et al. 1956) incorporated critical thinking abilities. Ennis (1962) proposed 12 aspects of critical thinking as a basis for research on the teaching and evaluation of critical thinking ability.

Since 1980, an annual international conference in California on critical thinking and educational reform has attracted tens of thousands of educators from all levels of education and from many parts of the world. Also since 1980, the state university system in California has required all undergraduate students to take a critical thinking course. Since 1983, the Association for Informal Logic and Critical Thinking has sponsored sessions in conjunction with the divisional meetings of the American Philosophical Association (APA). In 1987, the APA’s Committee on Pre-College Philosophy commissioned a consensus statement on critical thinking for purposes of educational assessment and instruction (Facione 1990a). Researchers have developed standardized tests of critical thinking abilities and dispositions; for details, see the Supplement on Assessment . Educational jurisdictions around the world now include critical thinking in guidelines for curriculum and assessment.

For details on this history, see the Supplement on History .

2. Examples and Non-Examples

Before considering the definition of critical thinking, it will be helpful to have in mind some examples of critical thinking, as well as some examples of kinds of thinking that would apparently not count as critical thinking.

Dewey (1910: 68–71; 1933: 91–94) takes as paradigms of reflective thinking three class papers of students in which they describe their thinking. The examples range from the everyday to the scientific.

Transit : “The other day, when I was down town on 16th Street, a clock caught my eye. I saw that the hands pointed to 12:20. This suggested that I had an engagement at 124th Street, at one o’clock. I reasoned that as it had taken me an hour to come down on a surface car, I should probably be twenty minutes late if I returned the same way. I might save twenty minutes by a subway express. But was there a station near? If not, I might lose more than twenty minutes in looking for one. Then I thought of the elevated, and I saw there was such a line within two blocks. But where was the station? If it were several blocks above or below the street I was on, I should lose time instead of gaining it. My mind went back to the subway express as quicker than the elevated; furthermore, I remembered that it went nearer than the elevated to the part of 124th Street I wished to reach, so that time would be saved at the end of the journey. I concluded in favor of the subway, and reached my destination by one o’clock.” (Dewey 1910: 68–69; 1933: 91–92)

Ferryboat : “Projecting nearly horizontally from the upper deck of the ferryboat on which I daily cross the river is a long white pole, having a gilded ball at its tip. It suggested a flagpole when I first saw it; its color, shape, and gilded ball agreed with this idea, and these reasons seemed to justify me in this belief. But soon difficulties presented themselves. The pole was nearly horizontal, an unusual position for a flagpole; in the next place, there was no pulley, ring, or cord by which to attach a flag; finally, there were elsewhere on the boat two vertical staffs from which flags were occasionally flown. It seemed probable that the pole was not there for flag-flying.

“I then tried to imagine all possible purposes of the pole, and to consider for which of these it was best suited: (a) Possibly it was an ornament. But as all the ferryboats and even the tugboats carried poles, this hypothesis was rejected. (b) Possibly it was the terminal of a wireless telegraph. But the same considerations made this improbable. Besides, the more natural place for such a terminal would be the highest part of the boat, on top of the pilot house. (c) Its purpose might be to point out the direction in which the boat is moving.

“In support of this conclusion, I discovered that the pole was lower than the pilot house, so that the steersman could easily see it. Moreover, the tip was enough higher than the base, so that, from the pilot’s position, it must appear to project far out in front of the boat. Moreover, the pilot being near the front of the boat, he would need some such guide as to its direction. Tugboats would also need poles for such a purpose. This hypothesis was so much more probable than the others that I accepted it. I formed the conclusion that the pole was set up for the purpose of showing the pilot the direction in which the boat pointed, to enable him to steer correctly.” (Dewey 1910: 69–70; 1933: 92–93)

Bubbles : “In washing tumblers in hot soapsuds and placing them mouth downward on a plate, bubbles appeared on the outside of the mouth of the tumblers and then went inside. Why? The presence of bubbles suggests air, which I note must come from inside the tumbler. I see that the soapy water on the plate prevents escape of the air save as it may be caught in bubbles. But why should air leave the tumbler? There was no substance entering to force it out. It must have expanded. It expands by increase of heat, or by decrease of pressure, or both. Could the air have become heated after the tumbler was taken from the hot suds? Clearly not the air that was already entangled in the water. If heated air was the cause, cold air must have entered in transferring the tumblers from the suds to the plate. I test to see if this supposition is true by taking several more tumblers out. Some I shake so as to make sure of entrapping cold air in them. Some I take out holding mouth downward in order to prevent cold air from entering. Bubbles appear on the outside of every one of the former and on none of the latter. I must be right in my inference. Air from the outside must have been expanded by the heat of the tumbler, which explains the appearance of the bubbles on the outside. But why do they then go inside? Cold contracts. The tumbler cooled and also the air inside it. Tension was removed, and hence bubbles appeared inside. To be sure of this, I test by placing a cup of ice on the tumbler while the bubbles are still forming outside. They soon reverse” (Dewey 1910: 70–71; 1933: 93–94).

Dewey (1910, 1933) sprinkles his book with other examples of critical thinking. We will refer to the following.

Weather : A man on a walk notices that it has suddenly become cool, thinks that it is probably going to rain, looks up and sees a dark cloud obscuring the sun, and quickens his steps (1910: 6–10; 1933: 9–13).

Disorder : A man finds his rooms on his return to them in disorder with his belongings thrown about, thinks at first of burglary as an explanation, then thinks of mischievous children as being an alternative explanation, then looks to see whether valuables are missing, and discovers that they are (1910: 82–83; 1933: 166–168).

Typhoid : A physician diagnosing a patient whose conspicuous symptoms suggest typhoid avoids drawing a conclusion until more data are gathered by questioning the patient and by making tests (1910: 85–86; 1933: 170).

Blur : A moving blur catches our eye in the distance, we ask ourselves whether it is a cloud of whirling dust or a tree moving its branches or a man signaling to us, we think of other traits that should be found on each of those possibilities, and we look and see if those traits are found (1910: 102, 108; 1933: 121, 133).

Suction pump : In thinking about the suction pump, the scientist first notes that it will draw water only to a maximum height of 33 feet at sea level and to a lesser maximum height at higher elevations, selects for attention the differing atmospheric pressure at these elevations, sets up experiments in which the air is removed from a vessel containing water (when suction no longer works) and in which the weight of air at various levels is calculated, compares the results of reasoning about the height to which a given weight of air will allow a suction pump to raise water with the observed maximum height at different elevations, and finally assimilates the suction pump to such apparently different phenomena as the siphon and the rising of a balloon (1910: 150–153; 1933: 195–198).

Diamond : A passenger in a car driving in a diamond lane reserved for vehicles with at least one passenger notices that the diamond marks on the pavement are far apart in some places and close together in others. Why? The driver suggests that the reason may be that the diamond marks are not needed where there is a solid double line separating the diamond lane from the adjoining lane, but are needed when there is a dotted single line permitting crossing into the diamond lane. Further observation confirms that the diamonds are close together when a dotted line separates the diamond lane from its neighbour, but otherwise far apart.

Rash : A woman suddenly develops a very itchy red rash on her throat and upper chest. She recently noticed a mark on the back of her right hand, but was not sure whether the mark was a rash or a scrape. She lies down in bed and thinks about what might be causing the rash and what to do about it. About two weeks before, she began taking blood pressure medication that contained a sulfa drug, and the pharmacist had warned her, in view of a previous allergic reaction to a medication containing a sulfa drug, to be on the alert for an allergic reaction; however, she had been taking the medication for two weeks with no such effect. The day before, she began using a new cream on her neck and upper chest; against the new cream as the cause was mark on the back of her hand, which had not been exposed to the cream. She began taking probiotics about a month before. She also recently started new eye drops, but she supposed that manufacturers of eye drops would be careful not to include allergy-causing components in the medication. The rash might be a heat rash, since she recently was sweating profusely from her upper body. Since she is about to go away on a short vacation, where she would not have access to her usual physician, she decides to keep taking the probiotics and using the new eye drops but to discontinue the blood pressure medication and to switch back to the old cream for her neck and upper chest. She forms a plan to consult her regular physician on her return about the blood pressure medication.

Candidate : Although Dewey included no examples of thinking directed at appraising the arguments of others, such thinking has come to be considered a kind of critical thinking. We find an example of such thinking in the performance task on the Collegiate Learning Assessment (CLA+), which its sponsoring organization describes as

a performance-based assessment that provides a measure of an institution’s contribution to the development of critical-thinking and written communication skills of its students. (Council for Aid to Education 2017)

A sample task posted on its website requires the test-taker to write a report for public distribution evaluating a fictional candidate’s policy proposals and their supporting arguments, using supplied background documents, with a recommendation on whether to endorse the candidate.

Immediate acceptance of an idea that suggests itself as a solution to a problem (e.g., a possible explanation of an event or phenomenon, an action that seems likely to produce a desired result) is “uncritical thinking, the minimum of reflection” (Dewey 1910: 13). On-going suspension of judgment in the light of doubt about a possible solution is not critical thinking (Dewey 1910: 108). Critique driven by a dogmatically held political or religious ideology is not critical thinking; thus Paulo Freire (1968 [1970]) is using the term (e.g., at 1970: 71, 81, 100, 146) in a more politically freighted sense that includes not only reflection but also revolutionary action against oppression. Derivation of a conclusion from given data using an algorithm is not critical thinking.

What is critical thinking? There are many definitions. Ennis (2016) lists 14 philosophically oriented scholarly definitions and three dictionary definitions. Following Rawls (1971), who distinguished his conception of justice from a utilitarian conception but regarded them as rival conceptions of the same concept, Ennis maintains that the 17 definitions are different conceptions of the same concept. Rawls articulated the shared concept of justice as

a characteristic set of principles for assigning basic rights and duties and for determining… the proper distribution of the benefits and burdens of social cooperation. (Rawls 1971: 5)

Bailin et al. (1999b) claim that, if one considers what sorts of thinking an educator would take not to be critical thinking and what sorts to be critical thinking, one can conclude that educators typically understand critical thinking to have at least three features.

• It is done for the purpose of making up one’s mind about what to believe or do.
• The person engaging in the thinking is trying to fulfill standards of adequacy and accuracy appropriate to the thinking.
• The thinking fulfills the relevant standards to some threshold level.

One could sum up the core concept that involves these three features by saying that critical thinking is careful goal-directed thinking. This core concept seems to apply to all the examples of critical thinking described in the previous section. As for the non-examples, their exclusion depends on construing careful thinking as excluding jumping immediately to conclusions, suspending judgment no matter how strong the evidence, reasoning from an unquestioned ideological or religious perspective, and routinely using an algorithm to answer a question.

If the core of critical thinking is careful goal-directed thinking, conceptions of it can vary according to its presumed scope, its presumed goal, one’s criteria and threshold for being careful, and the thinking component on which one focuses. As to its scope, some conceptions (e.g., Dewey 1910, 1933) restrict it to constructive thinking on the basis of one’s own observations and experiments, others (e.g., Ennis 1962; Fisher & Scriven 1997; Johnson 1992) to appraisal of the products of such thinking. Ennis (1991) and Bailin et al. (1999b) take it to cover both construction and appraisal. As to its goal, some conceptions restrict it to forming a judgment (Dewey 1910, 1933; Lipman 1987; Facione 1990a). Others allow for actions as well as beliefs as the end point of a process of critical thinking (Ennis 1991; Bailin et al. 1999b). As to the criteria and threshold for being careful, definitions vary in the term used to indicate that critical thinking satisfies certain norms: “intellectually disciplined” (Scriven & Paul 1987), “reasonable” (Ennis 1991), “skillful” (Lipman 1987), “skilled” (Fisher & Scriven 1997), “careful” (Bailin & Battersby 2009). Some definitions specify these norms, referring variously to “consideration of any belief or supposed form of knowledge in the light of the grounds that support it and the further conclusions to which it tends” (Dewey 1910, 1933); “the methods of logical inquiry and reasoning” (Glaser 1941); “conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication” (Scriven & Paul 1987); the requirement that “it is sensitive to context, relies on criteria, and is self-correcting” (Lipman 1987); “evidential, conceptual, methodological, criteriological, or contextual considerations” (Facione 1990a); and “plus-minus considerations of the product in terms of appropriate standards (or criteria)” (Johnson 1992). Stanovich and Stanovich (2010) propose to ground the concept of critical thinking in the concept of rationality, which they understand as combining epistemic rationality (fitting one’s beliefs to the world) and instrumental rationality (optimizing goal fulfillment); a critical thinker, in their view, is someone with “a propensity to override suboptimal responses from the autonomous mind” (2010: 227). These variant specifications of norms for critical thinking are not necessarily incompatible with one another, and in any case presuppose the core notion of thinking carefully. As to the thinking component singled out, some definitions focus on suspension of judgment during the thinking (Dewey 1910; McPeck 1981), others on inquiry while judgment is suspended (Bailin & Battersby 2009, 2021), others on the resulting judgment (Facione 1990a), and still others on responsiveness to reasons (Siegel 1988). Kuhn (2019) takes critical thinking to be more a dialogic practice of advancing and responding to arguments than an individual ability.

In educational contexts, a definition of critical thinking is a “programmatic definition” (Scheffler 1960: 19). It expresses a practical program for achieving an educational goal. For this purpose, a one-sentence formulaic definition is much less useful than articulation of a critical thinking process, with criteria and standards for the kinds of thinking that the process may involve. The real educational goal is recognition, adoption and implementation by students of those criteria and standards. That adoption and implementation in turn consists in acquiring the knowledge, abilities and dispositions of a critical thinker.

Conceptions of critical thinking generally do not include moral integrity as part of the concept. Dewey, for example, took critical thinking to be the ultimate intellectual goal of education, but distinguished it from the development of social cooperation among school children, which he took to be the central moral goal. Ennis (1996, 2011) added to his previous list of critical thinking dispositions a group of dispositions to care about the dignity and worth of every person, which he described as a “correlative” (1996) disposition without which critical thinking would be less valuable and perhaps harmful. An educational program that aimed at developing critical thinking but not the correlative disposition to care about the dignity and worth of every person, he asserted, “would be deficient and perhaps dangerous” (Ennis 1996: 172).

Dewey thought that education for reflective thinking would be of value to both the individual and society; recognition in educational practice of the kinship to the scientific attitude of children’s native curiosity, fertile imagination and love of experimental inquiry “would make for individual happiness and the reduction of social waste” (Dewey 1910: iii). Schools participating in the Eight-Year Study took development of the habit of reflective thinking and skill in solving problems as a means to leading young people to understand, appreciate and live the democratic way of life characteristic of the United States (Aikin 1942: 17–18, 81). Harvey Siegel (1988: 55–61) has offered four considerations in support of adopting critical thinking as an educational ideal. (1) Respect for persons requires that schools and teachers honour students’ demands for reasons and explanations, deal with students honestly, and recognize the need to confront students’ independent judgment; these requirements concern the manner in which teachers treat students. (2) Education has the task of preparing children to be successful adults, a task that requires development of their self-sufficiency. (3) Education should initiate children into the rational traditions in such fields as history, science and mathematics. (4) Education should prepare children to become democratic citizens, which requires reasoned procedures and critical talents and attitudes. To supplement these considerations, Siegel (1988: 62–90) responds to two objections: the ideology objection that adoption of any educational ideal requires a prior ideological commitment and the indoctrination objection that cultivation of critical thinking cannot escape being a form of indoctrination.

Despite the diversity of our 11 examples, one can recognize a common pattern. Dewey analyzed it as consisting of five phases:

• suggestions , in which the mind leaps forward to a possible solution;
• an intellectualization of the difficulty or perplexity into a problem to be solved, a question for which the answer must be sought;
• the use of one suggestion after another as a leading idea, or hypothesis , to initiate and guide observation and other operations in collection of factual material;
• the mental elaboration of the idea or supposition as an idea or supposition ( reasoning , in the sense on which reasoning is a part, not the whole, of inference); and
• testing the hypothesis by overt or imaginative action. (Dewey 1933: 106–107; italics in original)

The process of reflective thinking consisting of these phases would be preceded by a perplexed, troubled or confused situation and followed by a cleared-up, unified, resolved situation (Dewey 1933: 106). The term ‘phases’ replaced the term ‘steps’ (Dewey 1910: 72), thus removing the earlier suggestion of an invariant sequence. Variants of the above analysis appeared in (Dewey 1916: 177) and (Dewey 1938: 101–119).

The variant formulations indicate the difficulty of giving a single logical analysis of such a varied process. The process of critical thinking may have a spiral pattern, with the problem being redefined in the light of obstacles to solving it as originally formulated. For example, the person in Transit might have concluded that getting to the appointment at the scheduled time was impossible and have reformulated the problem as that of rescheduling the appointment for a mutually convenient time. Further, defining a problem does not always follow after or lead immediately to an idea of a suggested solution. Nor should it do so, as Dewey himself recognized in describing the physician in Typhoid as avoiding any strong preference for this or that conclusion before getting further information (Dewey 1910: 85; 1933: 170). People with a hypothesis in mind, even one to which they have a very weak commitment, have a so-called “confirmation bias” (Nickerson 1998): they are likely to pay attention to evidence that confirms the hypothesis and to ignore evidence that counts against it or for some competing hypothesis. Detectives, intelligence agencies, and investigators of airplane accidents are well advised to gather relevant evidence systematically and to postpone even tentative adoption of an explanatory hypothesis until the collected evidence rules out with the appropriate degree of certainty all but one explanation. Dewey’s analysis of the critical thinking process can be faulted as well for requiring acceptance or rejection of a possible solution to a defined problem, with no allowance for deciding in the light of the available evidence to suspend judgment. Further, given the great variety of kinds of problems for which reflection is appropriate, there is likely to be variation in its component events. Perhaps the best way to conceptualize the critical thinking process is as a checklist whose component events can occur in a variety of orders, selectively, and more than once. These component events might include (1) noticing a difficulty, (2) defining the problem, (3) dividing the problem into manageable sub-problems, (4) formulating a variety of possible solutions to the problem or sub-problem, (5) determining what evidence is relevant to deciding among possible solutions to the problem or sub-problem, (6) devising a plan of systematic observation or experiment that will uncover the relevant evidence, (7) carrying out the plan of systematic observation or experimentation, (8) noting the results of the systematic observation or experiment, (9) gathering relevant testimony and information from others, (10) judging the credibility of testimony and information gathered from others, (11) drawing conclusions from gathered evidence and accepted testimony, and (12) accepting a solution that the evidence adequately supports (cf. Hitchcock 2017: 485).

Checklist conceptions of the process of critical thinking are open to the objection that they are too mechanical and procedural to fit the multi-dimensional and emotionally charged issues for which critical thinking is urgently needed (Paul 1984). For such issues, a more dialectical process is advocated, in which competing relevant world views are identified, their implications explored, and some sort of creative synthesis attempted.

If one considers the critical thinking process illustrated by the 11 examples, one can identify distinct kinds of mental acts and mental states that form part of it. To distinguish, label and briefly characterize these components is a useful preliminary to identifying abilities, skills, dispositions, attitudes, habits and the like that contribute causally to thinking critically. Identifying such abilities and habits is in turn a useful preliminary to setting educational goals. Setting the goals is in its turn a useful preliminary to designing strategies for helping learners to achieve the goals and to designing ways of measuring the extent to which learners have done so. Such measures provide both feedback to learners on their achievement and a basis for experimental research on the effectiveness of various strategies for educating people to think critically. Let us begin, then, by distinguishing the kinds of mental acts and mental events that can occur in a critical thinking process.

• Observing : One notices something in one’s immediate environment (sudden cooling of temperature in Weather , bubbles forming outside a glass and then going inside in Bubbles , a moving blur in the distance in Blur , a rash in Rash ). Or one notes the results of an experiment or systematic observation (valuables missing in Disorder , no suction without air pressure in Suction pump )
• Feeling : One feels puzzled or uncertain about something (how to get to an appointment on time in Transit , why the diamonds vary in spacing in Diamond ). One wants to resolve this perplexity. One feels satisfaction once one has worked out an answer (to take the subway express in Transit , diamonds closer when needed as a warning in Diamond ).
• Wondering : One formulates a question to be addressed (why bubbles form outside a tumbler taken from hot water in Bubbles , how suction pumps work in Suction pump , what caused the rash in Rash ).
• Imagining : One thinks of possible answers (bus or subway or elevated in Transit , flagpole or ornament or wireless communication aid or direction indicator in Ferryboat , allergic reaction or heat rash in Rash ).
• Inferring : One works out what would be the case if a possible answer were assumed (valuables missing if there has been a burglary in Disorder , earlier start to the rash if it is an allergic reaction to a sulfa drug in Rash ). Or one draws a conclusion once sufficient relevant evidence is gathered (take the subway in Transit , burglary in Disorder , discontinue blood pressure medication and new cream in Rash ).
• Knowledge : One uses stored knowledge of the subject-matter to generate possible answers or to infer what would be expected on the assumption of a particular answer (knowledge of a city’s public transit system in Transit , of the requirements for a flagpole in Ferryboat , of Boyle’s law in Bubbles , of allergic reactions in Rash ).
• Experimenting : One designs and carries out an experiment or a systematic observation to find out whether the results deduced from a possible answer will occur (looking at the location of the flagpole in relation to the pilot’s position in Ferryboat , putting an ice cube on top of a tumbler taken from hot water in Bubbles , measuring the height to which a suction pump will draw water at different elevations in Suction pump , noticing the spacing of diamonds when movement to or from a diamond lane is allowed in Diamond ).
• Consulting : One finds a source of information, gets the information from the source, and makes a judgment on whether to accept it. None of our 11 examples include searching for sources of information. In this respect they are unrepresentative, since most people nowadays have almost instant access to information relevant to answering any question, including many of those illustrated by the examples. However, Candidate includes the activities of extracting information from sources and evaluating its credibility.
• Identifying and analyzing arguments : One notices an argument and works out its structure and content as a preliminary to evaluating its strength. This activity is central to Candidate . It is an important part of a critical thinking process in which one surveys arguments for various positions on an issue.
• Judging : One makes a judgment on the basis of accumulated evidence and reasoning, such as the judgment in Ferryboat that the purpose of the pole is to provide direction to the pilot.
• Deciding : One makes a decision on what to do or on what policy to adopt, as in the decision in Transit to take the subway.

By definition, a person who does something voluntarily is both willing and able to do that thing at that time. Both the willingness and the ability contribute causally to the person’s action, in the sense that the voluntary action would not occur if either (or both) of these were lacking. For example, suppose that one is standing with one’s arms at one’s sides and one voluntarily lifts one’s right arm to an extended horizontal position. One would not do so if one were unable to lift one’s arm, if for example one’s right side was paralyzed as the result of a stroke. Nor would one do so if one were unwilling to lift one’s arm, if for example one were participating in a street demonstration at which a white supremacist was urging the crowd to lift their right arm in a Nazi salute and one were unwilling to express support in this way for the racist Nazi ideology. The same analysis applies to a voluntary mental process of thinking critically. It requires both willingness and ability to think critically, including willingness and ability to perform each of the mental acts that compose the process and to coordinate those acts in a sequence that is directed at resolving the initiating perplexity.

Consider willingness first. We can identify causal contributors to willingness to think critically by considering factors that would cause a person who was able to think critically about an issue nevertheless not to do so (Hamby 2014). For each factor, the opposite condition thus contributes causally to willingness to think critically on a particular occasion. For example, people who habitually jump to conclusions without considering alternatives will not think critically about issues that arise, even if they have the required abilities. The contrary condition of willingness to suspend judgment is thus a causal contributor to thinking critically.

Now consider ability. In contrast to the ability to move one’s arm, which can be completely absent because a stroke has left the arm paralyzed, the ability to think critically is a developed ability, whose absence is not a complete absence of ability to think but absence of ability to think well. We can identify the ability to think well directly, in terms of the norms and standards for good thinking. In general, to be able do well the thinking activities that can be components of a critical thinking process, one needs to know the concepts and principles that characterize their good performance, to recognize in particular cases that the concepts and principles apply, and to apply them. The knowledge, recognition and application may be procedural rather than declarative. It may be domain-specific rather than widely applicable, and in either case may need subject-matter knowledge, sometimes of a deep kind.

Reflections of the sort illustrated by the previous two paragraphs have led scholars to identify the knowledge, abilities and dispositions of a “critical thinker”, i.e., someone who thinks critically whenever it is appropriate to do so. We turn now to these three types of causal contributors to thinking critically. We start with dispositions, since arguably these are the most powerful contributors to being a critical thinker, can be fostered at an early stage of a child’s development, and are susceptible to general improvement (Glaser 1941: 175)

8. Critical Thinking Dispositions

Educational researchers use the term ‘dispositions’ broadly for the habits of mind and attitudes that contribute causally to being a critical thinker. Some writers (e.g., Paul & Elder 2006; Hamby 2014; Bailin & Battersby 2016a) propose to use the term ‘virtues’ for this dimension of a critical thinker. The virtues in question, although they are virtues of character, concern the person’s ways of thinking rather than the person’s ways of behaving towards others. They are not moral virtues but intellectual virtues, of the sort articulated by Zagzebski (1996) and discussed by Turri, Alfano, and Greco (2017).

On a realistic conception, thinking dispositions or intellectual virtues are real properties of thinkers. They are general tendencies, propensities, or inclinations to think in particular ways in particular circumstances, and can be genuinely explanatory (Siegel 1999). Sceptics argue that there is no evidence for a specific mental basis for the habits of mind that contribute to thinking critically, and that it is pedagogically misleading to posit such a basis (Bailin et al. 1999a). Whatever their status, critical thinking dispositions need motivation for their initial formation in a child—motivation that may be external or internal. As children develop, the force of habit will gradually become important in sustaining the disposition (Nieto & Valenzuela 2012). Mere force of habit, however, is unlikely to sustain critical thinking dispositions. Critical thinkers must value and enjoy using their knowledge and abilities to think things through for themselves. They must be committed to, and lovers of, inquiry.

A person may have a critical thinking disposition with respect to only some kinds of issues. For example, one could be open-minded about scientific issues but not about religious issues. Similarly, one could be confident in one’s ability to reason about the theological implications of the existence of evil in the world but not in one’s ability to reason about the best design for a guided ballistic missile.

Facione (1990a: 25) divides “affective dispositions” of critical thinking into approaches to life and living in general and approaches to specific issues, questions or problems. Adapting this distinction, one can usefully divide critical thinking dispositions into initiating dispositions (those that contribute causally to starting to think critically about an issue) and internal dispositions (those that contribute causally to doing a good job of thinking critically once one has started). The two categories are not mutually exclusive. For example, open-mindedness, in the sense of willingness to consider alternative points of view to one’s own, is both an initiating and an internal disposition.

Using the strategy of considering factors that would block people with the ability to think critically from doing so, we can identify as initiating dispositions for thinking critically attentiveness, a habit of inquiry, self-confidence, courage, open-mindedness, willingness to suspend judgment, trust in reason, wanting evidence for one’s beliefs, and seeking the truth. We consider briefly what each of these dispositions amounts to, in each case citing sources that acknowledge them.

• Attentiveness : One will not think critically if one fails to recognize an issue that needs to be thought through. For example, the pedestrian in Weather would not have looked up if he had not noticed that the air was suddenly cooler. To be a critical thinker, then, one needs to be habitually attentive to one’s surroundings, noticing not only what one senses but also sources of perplexity in messages received and in one’s own beliefs and attitudes (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Habit of inquiry : Inquiry is effortful, and one needs an internal push to engage in it. For example, the student in Bubbles could easily have stopped at idle wondering about the cause of the bubbles rather than reasoning to a hypothesis, then designing and executing an experiment to test it. Thus willingness to think critically needs mental energy and initiative. What can supply that energy? Love of inquiry, or perhaps just a habit of inquiry. Hamby (2015) has argued that willingness to inquire is the central critical thinking virtue, one that encompasses all the others. It is recognized as a critical thinking disposition by Dewey (1910: 29; 1933: 35), Glaser (1941: 5), Ennis (1987: 12; 1991: 8), Facione (1990a: 25), Bailin et al. (1999b: 294), Halpern (1998: 452), and Facione, Facione, & Giancarlo (2001).
• Self-confidence : Lack of confidence in one’s abilities can block critical thinking. For example, if the woman in Rash lacked confidence in her ability to figure things out for herself, she might just have assumed that the rash on her chest was the allergic reaction to her medication against which the pharmacist had warned her. Thus willingness to think critically requires confidence in one’s ability to inquire (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
• Courage : Fear of thinking for oneself can stop one from doing it. Thus willingness to think critically requires intellectual courage (Paul & Elder 2006: 16).
• Open-mindedness : A dogmatic attitude will impede thinking critically. For example, a person who adheres rigidly to a “pro-choice” position on the issue of the legal status of induced abortion is likely to be unwilling to consider seriously the issue of when in its development an unborn child acquires a moral right to life. Thus willingness to think critically requires open-mindedness, in the sense of a willingness to examine questions to which one already accepts an answer but which further evidence or reasoning might cause one to answer differently (Dewey 1933; Facione 1990a; Ennis 1991; Bailin et al. 1999b; Halpern 1998, Facione, Facione, & Giancarlo 2001). Paul (1981) emphasizes open-mindedness about alternative world-views, and recommends a dialectical approach to integrating such views as central to what he calls “strong sense” critical thinking. In three studies, Haran, Ritov, & Mellers (2013) found that actively open-minded thinking, including “the tendency to weigh new evidence against a favored belief, to spend sufficient time on a problem before giving up, and to consider carefully the opinions of others in forming one’s own”, led study participants to acquire information and thus to make accurate estimations.
• Willingness to suspend judgment : Premature closure on an initial solution will block critical thinking. Thus willingness to think critically requires a willingness to suspend judgment while alternatives are explored (Facione 1990a; Ennis 1991; Halpern 1998).
• Trust in reason : Since distrust in the processes of reasoned inquiry will dissuade one from engaging in it, trust in them is an initiating critical thinking disposition (Facione 1990a, 25; Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001; Paul & Elder 2006). In reaction to an allegedly exclusive emphasis on reason in critical thinking theory and pedagogy, Thayer-Bacon (2000) argues that intuition, imagination, and emotion have important roles to play in an adequate conception of critical thinking that she calls “constructive thinking”. From her point of view, critical thinking requires trust not only in reason but also in intuition, imagination, and emotion.
• Seeking the truth : If one does not care about the truth but is content to stick with one’s initial bias on an issue, then one will not think critically about it. Seeking the truth is thus an initiating critical thinking disposition (Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001). A disposition to seek the truth is implicit in more specific critical thinking dispositions, such as trying to be well-informed, considering seriously points of view other than one’s own, looking for alternatives, suspending judgment when the evidence is insufficient, and adopting a position when the evidence supporting it is sufficient.

Some of the initiating dispositions, such as open-mindedness and willingness to suspend judgment, are also internal critical thinking dispositions, in the sense of mental habits or attitudes that contribute causally to doing a good job of critical thinking once one starts the process. But there are many other internal critical thinking dispositions. Some of them are parasitic on one’s conception of good thinking. For example, it is constitutive of good thinking about an issue to formulate the issue clearly and to maintain focus on it. For this purpose, one needs not only the corresponding ability but also the corresponding disposition. Ennis (1991: 8) describes it as the disposition “to determine and maintain focus on the conclusion or question”, Facione (1990a: 25) as “clarity in stating the question or concern”. Other internal dispositions are motivators to continue or adjust the critical thinking process, such as willingness to persist in a complex task and willingness to abandon nonproductive strategies in an attempt to self-correct (Halpern 1998: 452). For a list of identified internal critical thinking dispositions, see the Supplement on Internal Critical Thinking Dispositions .

Some theorists postulate skills, i.e., acquired abilities, as operative in critical thinking. It is not obvious, however, that a good mental act is the exercise of a generic acquired skill. Inferring an expected time of arrival, as in Transit , has some generic components but also uses non-generic subject-matter knowledge. Bailin et al. (1999a) argue against viewing critical thinking skills as generic and discrete, on the ground that skilled performance at a critical thinking task cannot be separated from knowledge of concepts and from domain-specific principles of good thinking. Talk of skills, they concede, is unproblematic if it means merely that a person with critical thinking skills is capable of intelligent performance.

Despite such scepticism, theorists of critical thinking have listed as general contributors to critical thinking what they variously call abilities (Glaser 1941; Ennis 1962, 1991), skills (Facione 1990a; Halpern 1998) or competencies (Fisher & Scriven 1997). Amalgamating these lists would produce a confusing and chaotic cornucopia of more than 50 possible educational objectives, with only partial overlap among them. It makes sense instead to try to understand the reasons for the multiplicity and diversity, and to make a selection according to one’s own reasons for singling out abilities to be developed in a critical thinking curriculum. Two reasons for diversity among lists of critical thinking abilities are the underlying conception of critical thinking and the envisaged educational level. Appraisal-only conceptions, for example, involve a different suite of abilities than constructive-only conceptions. Some lists, such as those in (Glaser 1941), are put forward as educational objectives for secondary school students, whereas others are proposed as objectives for college students (e.g., Facione 1990a).

The abilities described in the remaining paragraphs of this section emerge from reflection on the general abilities needed to do well the thinking activities identified in section 6 as components of the critical thinking process described in section 5 . The derivation of each collection of abilities is accompanied by citation of sources that list such abilities and of standardized tests that claim to test them.

Observational abilities : Careful and accurate observation sometimes requires specialist expertise and practice, as in the case of observing birds and observing accident scenes. However, there are general abilities of noticing what one’s senses are picking up from one’s environment and of being able to articulate clearly and accurately to oneself and others what one has observed. It helps in exercising them to be able to recognize and take into account factors that make one’s observation less trustworthy, such as prior framing of the situation, inadequate time, deficient senses, poor observation conditions, and the like. It helps as well to be skilled at taking steps to make one’s observation more trustworthy, such as moving closer to get a better look, measuring something three times and taking the average, and checking what one thinks one is observing with someone else who is in a good position to observe it. It also helps to be skilled at recognizing respects in which one’s report of one’s observation involves inference rather than direct observation, so that one can then consider whether the inference is justified. These abilities come into play as well when one thinks about whether and with what degree of confidence to accept an observation report, for example in the study of history or in a criminal investigation or in assessing news reports. Observational abilities show up in some lists of critical thinking abilities (Ennis 1962: 90; Facione 1990a: 16; Ennis 1991: 9). There are items testing a person’s ability to judge the credibility of observation reports in the Cornell Critical Thinking Tests, Levels X and Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). Norris and King (1983, 1985, 1990a, 1990b) is a test of ability to appraise observation reports.

Emotional abilities : The emotions that drive a critical thinking process are perplexity or puzzlement, a wish to resolve it, and satisfaction at achieving the desired resolution. Children experience these emotions at an early age, without being trained to do so. Education that takes critical thinking as a goal needs only to channel these emotions and to make sure not to stifle them. Collaborative critical thinking benefits from ability to recognize one’s own and others’ emotional commitments and reactions.

Questioning abilities : A critical thinking process needs transformation of an inchoate sense of perplexity into a clear question. Formulating a question well requires not building in questionable assumptions, not prejudging the issue, and using language that in context is unambiguous and precise enough (Ennis 1962: 97; 1991: 9).

Imaginative abilities : Thinking directed at finding the correct causal explanation of a general phenomenon or particular event requires an ability to imagine possible explanations. Thinking about what policy or plan of action to adopt requires generation of options and consideration of possible consequences of each option. Domain knowledge is required for such creative activity, but a general ability to imagine alternatives is helpful and can be nurtured so as to become easier, quicker, more extensive, and deeper (Dewey 1910: 34–39; 1933: 40–47). Facione (1990a) and Halpern (1998) include the ability to imagine alternatives as a critical thinking ability.

Inferential abilities : The ability to draw conclusions from given information, and to recognize with what degree of certainty one’s own or others’ conclusions follow, is universally recognized as a general critical thinking ability. All 11 examples in section 2 of this article include inferences, some from hypotheses or options (as in Transit , Ferryboat and Disorder ), others from something observed (as in Weather and Rash ). None of these inferences is formally valid. Rather, they are licensed by general, sometimes qualified substantive rules of inference (Toulmin 1958) that rest on domain knowledge—that a bus trip takes about the same time in each direction, that the terminal of a wireless telegraph would be located on the highest possible place, that sudden cooling is often followed by rain, that an allergic reaction to a sulfa drug generally shows up soon after one starts taking it. It is a matter of controversy to what extent the specialized ability to deduce conclusions from premisses using formal rules of inference is needed for critical thinking. Dewey (1933) locates logical forms in setting out the products of reflection rather than in the process of reflection. Ennis (1981a), on the other hand, maintains that a liberally-educated person should have the following abilities: to translate natural-language statements into statements using the standard logical operators, to use appropriately the language of necessary and sufficient conditions, to deal with argument forms and arguments containing symbols, to determine whether in virtue of an argument’s form its conclusion follows necessarily from its premisses, to reason with logically complex propositions, and to apply the rules and procedures of deductive logic. Inferential abilities are recognized as critical thinking abilities by Glaser (1941: 6), Facione (1990a: 9), Ennis (1991: 9), Fisher & Scriven (1997: 99, 111), and Halpern (1998: 452). Items testing inferential abilities constitute two of the five subtests of the Watson Glaser Critical Thinking Appraisal (Watson & Glaser 1980a, 1980b, 1994), two of the four sections in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), three of the seven sections in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), 11 of the 34 items on Forms A and B of the California Critical Thinking Skills Test (Facione 1990b, 1992), and a high but variable proportion of the 25 selected-response questions in the Collegiate Learning Assessment (Council for Aid to Education 2017).

Experimenting abilities : Knowing how to design and execute an experiment is important not just in scientific research but also in everyday life, as in Rash . Dewey devoted a whole chapter of his How We Think (1910: 145–156; 1933: 190–202) to the superiority of experimentation over observation in advancing knowledge. Experimenting abilities come into play at one remove in appraising reports of scientific studies. Skill in designing and executing experiments includes the acknowledged abilities to appraise evidence (Glaser 1941: 6), to carry out experiments and to apply appropriate statistical inference techniques (Facione 1990a: 9), to judge inductions to an explanatory hypothesis (Ennis 1991: 9), and to recognize the need for an adequately large sample size (Halpern 1998). The Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) includes four items (out of 52) on experimental design. The Collegiate Learning Assessment (Council for Aid to Education 2017) makes room for appraisal of study design in both its performance task and its selected-response questions.

Consulting abilities : Skill at consulting sources of information comes into play when one seeks information to help resolve a problem, as in Candidate . Ability to find and appraise information includes ability to gather and marshal pertinent information (Glaser 1941: 6), to judge whether a statement made by an alleged authority is acceptable (Ennis 1962: 84), to plan a search for desired information (Facione 1990a: 9), and to judge the credibility of a source (Ennis 1991: 9). Ability to judge the credibility of statements is tested by 24 items (out of 76) in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) and by four items (out of 52) in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). The College Learning Assessment’s performance task requires evaluation of whether information in documents is credible or unreliable (Council for Aid to Education 2017).

Argument analysis abilities : The ability to identify and analyze arguments contributes to the process of surveying arguments on an issue in order to form one’s own reasoned judgment, as in Candidate . The ability to detect and analyze arguments is recognized as a critical thinking skill by Facione (1990a: 7–8), Ennis (1991: 9) and Halpern (1998). Five items (out of 34) on the California Critical Thinking Skills Test (Facione 1990b, 1992) test skill at argument analysis. The College Learning Assessment (Council for Aid to Education 2017) incorporates argument analysis in its selected-response tests of critical reading and evaluation and of critiquing an argument.

Judging skills and deciding skills : Skill at judging and deciding is skill at recognizing what judgment or decision the available evidence and argument supports, and with what degree of confidence. It is thus a component of the inferential skills already discussed.

Lists and tests of critical thinking abilities often include two more abilities: identifying assumptions and constructing and evaluating definitions.

In addition to dispositions and abilities, critical thinking needs knowledge: of critical thinking concepts, of critical thinking principles, and of the subject-matter of the thinking.

We can derive a short list of concepts whose understanding contributes to critical thinking from the critical thinking abilities described in the preceding section. Observational abilities require an understanding of the difference between observation and inference. Questioning abilities require an understanding of the concepts of ambiguity and vagueness. Inferential abilities require an understanding of the difference between conclusive and defeasible inference (traditionally, between deduction and induction), as well as of the difference between necessary and sufficient conditions. Experimenting abilities require an understanding of the concepts of hypothesis, null hypothesis, assumption and prediction, as well as of the concept of statistical significance and of its difference from importance. They also require an understanding of the difference between an experiment and an observational study, and in particular of the difference between a randomized controlled trial, a prospective correlational study and a retrospective (case-control) study. Argument analysis abilities require an understanding of the concepts of argument, premiss, assumption, conclusion and counter-consideration. Additional critical thinking concepts are proposed by Bailin et al. (1999b: 293), Fisher & Scriven (1997: 105–106), Black (2012), and Blair (2021).

According to Glaser (1941: 25), ability to think critically requires knowledge of the methods of logical inquiry and reasoning. If we review the list of abilities in the preceding section, however, we can see that some of them can be acquired and exercised merely through practice, possibly guided in an educational setting, followed by feedback. Searching intelligently for a causal explanation of some phenomenon or event requires that one consider a full range of possible causal contributors, but it seems more important that one implements this principle in one’s practice than that one is able to articulate it. What is important is “operational knowledge” of the standards and principles of good thinking (Bailin et al. 1999b: 291–293). But the development of such critical thinking abilities as designing an experiment or constructing an operational definition can benefit from learning their underlying theory. Further, explicit knowledge of quirks of human thinking seems useful as a cautionary guide. Human memory is not just fallible about details, as people learn from their own experiences of misremembering, but is so malleable that a detailed, clear and vivid recollection of an event can be a total fabrication (Loftus 2017). People seek or interpret evidence in ways that are partial to their existing beliefs and expectations, often unconscious of their “confirmation bias” (Nickerson 1998). Not only are people subject to this and other cognitive biases (Kahneman 2011), of which they are typically unaware, but it may be counter-productive for one to make oneself aware of them and try consciously to counteract them or to counteract social biases such as racial or sexual stereotypes (Kenyon & Beaulac 2014). It is helpful to be aware of these facts and of the superior effectiveness of blocking the operation of biases—for example, by making an immediate record of one’s observations, refraining from forming a preliminary explanatory hypothesis, blind refereeing, double-blind randomized trials, and blind grading of students’ work. It is also helpful to be aware of the prevalence of “noise” (unwanted unsystematic variability of judgments), of how to detect noise (through a noise audit), and of how to reduce noise: make accuracy the goal, think statistically, break a process of arriving at a judgment into independent tasks, resist premature intuitions, in a group get independent judgments first, favour comparative judgments and scales (Kahneman, Sibony, & Sunstein 2021). It is helpful as well to be aware of the concept of “bounded rationality” in decision-making and of the related distinction between “satisficing” and optimizing (Simon 1956; Gigerenzer 2001).

Critical thinking about an issue requires substantive knowledge of the domain to which the issue belongs. Critical thinking abilities are not a magic elixir that can be applied to any issue whatever by somebody who has no knowledge of the facts relevant to exploring that issue. For example, the student in Bubbles needed to know that gases do not penetrate solid objects like a glass, that air expands when heated, that the volume of an enclosed gas varies directly with its temperature and inversely with its pressure, and that hot objects will spontaneously cool down to the ambient temperature of their surroundings unless kept hot by insulation or a source of heat. Critical thinkers thus need a rich fund of subject-matter knowledge relevant to the variety of situations they encounter. This fact is recognized in the inclusion among critical thinking dispositions of a concern to become and remain generally well informed.

Experimental educational interventions, with control groups, have shown that education can improve critical thinking skills and dispositions, as measured by standardized tests. For information about these tests, see the Supplement on Assessment .

What educational methods are most effective at developing the dispositions, abilities and knowledge of a critical thinker? In a comprehensive meta-analysis of experimental and quasi-experimental studies of strategies for teaching students to think critically, Abrami et al. (2015) found that dialogue, anchored instruction, and mentoring each increased the effectiveness of the educational intervention, and that they were most effective when combined. They also found that in these studies a combination of separate instruction in critical thinking with subject-matter instruction in which students are encouraged to think critically was more effective than either by itself. However, the difference was not statistically significant; that is, it might have arisen by chance.

Most of these studies lack the longitudinal follow-up required to determine whether the observed differential improvements in critical thinking abilities or dispositions continue over time, for example until high school or college graduation. For details on studies of methods of developing critical thinking skills and dispositions, see the Supplement on Educational Methods .

12. Controversies

Scholars have denied the generalizability of critical thinking abilities across subject domains, have alleged bias in critical thinking theory and pedagogy, and have investigated the relationship of critical thinking to other kinds of thinking.

McPeck (1981) attacked the thinking skills movement of the 1970s, including the critical thinking movement. He argued that there are no general thinking skills, since thinking is always thinking about some subject-matter. It is futile, he claimed, for schools and colleges to teach thinking as if it were a separate subject. Rather, teachers should lead their pupils to become autonomous thinkers by teaching school subjects in a way that brings out their cognitive structure and that encourages and rewards discussion and argument. As some of his critics (e.g., Paul 1985; Siegel 1985) pointed out, McPeck’s central argument needs elaboration, since it has obvious counter-examples in writing and speaking, for which (up to a certain level of complexity) there are teachable general abilities even though they are always about some subject-matter. To make his argument convincing, McPeck needs to explain how thinking differs from writing and speaking in a way that does not permit useful abstraction of its components from the subject-matters with which it deals. He has not done so. Nevertheless, his position that the dispositions and abilities of a critical thinker are best developed in the context of subject-matter instruction is shared by many theorists of critical thinking, including Dewey (1910, 1933), Glaser (1941), Passmore (1980), Weinstein (1990), Bailin et al. (1999b), and Willingham (2019).

McPeck’s challenge prompted reflection on the extent to which critical thinking is subject-specific. McPeck argued for a strong subject-specificity thesis, according to which it is a conceptual truth that all critical thinking abilities are specific to a subject. (He did not however extend his subject-specificity thesis to critical thinking dispositions. In particular, he took the disposition to suspend judgment in situations of cognitive dissonance to be a general disposition.) Conceptual subject-specificity is subject to obvious counter-examples, such as the general ability to recognize confusion of necessary and sufficient conditions. A more modest thesis, also endorsed by McPeck, is epistemological subject-specificity, according to which the norms of good thinking vary from one field to another. Epistemological subject-specificity clearly holds to a certain extent; for example, the principles in accordance with which one solves a differential equation are quite different from the principles in accordance with which one determines whether a painting is a genuine Picasso. But the thesis suffers, as Ennis (1989) points out, from vagueness of the concept of a field or subject and from the obvious existence of inter-field principles, however broadly the concept of a field is construed. For example, the principles of hypothetico-deductive reasoning hold for all the varied fields in which such reasoning occurs. A third kind of subject-specificity is empirical subject-specificity, according to which as a matter of empirically observable fact a person with the abilities and dispositions of a critical thinker in one area of investigation will not necessarily have them in another area of investigation.

The thesis of empirical subject-specificity raises the general problem of transfer. If critical thinking abilities and dispositions have to be developed independently in each school subject, how are they of any use in dealing with the problems of everyday life and the political and social issues of contemporary society, most of which do not fit into the framework of a traditional school subject? Proponents of empirical subject-specificity tend to argue that transfer is more likely to occur if there is critical thinking instruction in a variety of domains, with explicit attention to dispositions and abilities that cut across domains. But evidence for this claim is scanty. There is a need for well-designed empirical studies that investigate the conditions that make transfer more likely.

It is common ground in debates about the generality or subject-specificity of critical thinking dispositions and abilities that critical thinking about any topic requires background knowledge about the topic. For example, the most sophisticated understanding of the principles of hypothetico-deductive reasoning is of no help unless accompanied by some knowledge of what might be plausible explanations of some phenomenon under investigation.

Critics have objected to bias in the theory, pedagogy and practice of critical thinking. Commentators (e.g., Alston 1995; Ennis 1998) have noted that anyone who takes a position has a bias in the neutral sense of being inclined in one direction rather than others. The critics, however, are objecting to bias in the pejorative sense of an unjustified favoring of certain ways of knowing over others, frequently alleging that the unjustly favoured ways are those of a dominant sex or culture (Bailin 1995). These ways favour:

• reinforcement of egocentric and sociocentric biases over dialectical engagement with opposing world-views (Paul 1981, 1984; Warren 1998)
• distancing from the object of inquiry over closeness to it (Martin 1992; Thayer-Bacon 1992)
• indifference to the situation of others over care for them (Martin 1992)
• orientation to thought over orientation to action (Martin 1992)
• being reasonable over caring to understand people’s ideas (Thayer-Bacon 1993)
• being neutral and objective over being embodied and situated (Thayer-Bacon 1995a)
• doubting over believing (Thayer-Bacon 1995b)
• reason over emotion, imagination and intuition (Thayer-Bacon 2000)
• solitary thinking over collaborative thinking (Thayer-Bacon 2000)
• written and spoken assignments over other forms of expression (Alston 2001)
• attention to written and spoken communications over attention to human problems (Alston 2001)
• winning debates in the public sphere over making and understanding meaning (Alston 2001)

A common thread in this smorgasbord of accusations is dissatisfaction with focusing on the logical analysis and evaluation of reasoning and arguments. While these authors acknowledge that such analysis and evaluation is part of critical thinking and should be part of its conceptualization and pedagogy, they insist that it is only a part. Paul (1981), for example, bemoans the tendency of atomistic teaching of methods of analyzing and evaluating arguments to turn students into more able sophists, adept at finding fault with positions and arguments with which they disagree but even more entrenched in the egocentric and sociocentric biases with which they began. Martin (1992) and Thayer-Bacon (1992) cite with approval the self-reported intimacy with their subject-matter of leading researchers in biology and medicine, an intimacy that conflicts with the distancing allegedly recommended in standard conceptions and pedagogy of critical thinking. Thayer-Bacon (2000) contrasts the embodied and socially embedded learning of her elementary school students in a Montessori school, who used their imagination, intuition and emotions as well as their reason, with conceptions of critical thinking as

thinking that is used to critique arguments, offer justifications, and make judgments about what are the good reasons, or the right answers. (Thayer-Bacon 2000: 127–128)

Alston (2001) reports that her students in a women’s studies class were able to see the flaws in the Cinderella myth that pervades much romantic fiction but in their own romantic relationships still acted as if all failures were the woman’s fault and still accepted the notions of love at first sight and living happily ever after. Students, she writes, should

be able to connect their intellectual critique to a more affective, somatic, and ethical account of making risky choices that have sexist, racist, classist, familial, sexual, or other consequences for themselves and those both near and far… critical thinking that reads arguments, texts, or practices merely on the surface without connections to feeling/desiring/doing or action lacks an ethical depth that should infuse the difference between mere cognitive activity and something we want to call critical thinking. (Alston 2001: 34)

Some critics portray such biases as unfair to women. Thayer-Bacon (1992), for example, has charged modern critical thinking theory with being sexist, on the ground that it separates the self from the object and causes one to lose touch with one’s inner voice, and thus stigmatizes women, who (she asserts) link self to object and listen to their inner voice. Her charge does not imply that women as a group are on average less able than men to analyze and evaluate arguments. Facione (1990c) found no difference by sex in performance on his California Critical Thinking Skills Test. Kuhn (1991: 280–281) found no difference by sex in either the disposition or the competence to engage in argumentative thinking.

The critics propose a variety of remedies for the biases that they allege. In general, they do not propose to eliminate or downplay critical thinking as an educational goal. Rather, they propose to conceptualize critical thinking differently and to change its pedagogy accordingly. Their pedagogical proposals arise logically from their objections. They can be summarized as follows:

• Focus on argument networks with dialectical exchanges reflecting contesting points of view rather than on atomic arguments, so as to develop “strong sense” critical thinking that transcends egocentric and sociocentric biases (Paul 1981, 1984).
• Foster closeness to the subject-matter and feeling connected to others in order to inform a humane democracy (Martin 1992).
• Develop “constructive thinking” as a social activity in a community of physically embodied and socially embedded inquirers with personal voices who value not only reason but also imagination, intuition and emotion (Thayer-Bacon 2000).
• In developing critical thinking in school subjects, treat as important neither skills nor dispositions but opening worlds of meaning (Alston 2001).
• Attend to the development of critical thinking dispositions as well as skills, and adopt the “critical pedagogy” practised and advocated by Freire (1968 [1970]) and hooks (1994) (Dalgleish, Girard, & Davies 2017).

A common thread in these proposals is treatment of critical thinking as a social, interactive, personally engaged activity like that of a quilting bee or a barn-raising (Thayer-Bacon 2000) rather than as an individual, solitary, distanced activity symbolized by Rodin’s The Thinker . One can get a vivid description of education with the former type of goal from the writings of bell hooks (1994, 2010). Critical thinking for her is open-minded dialectical exchange across opposing standpoints and from multiple perspectives, a conception similar to Paul’s “strong sense” critical thinking (Paul 1981). She abandons the structure of domination in the traditional classroom. In an introductory course on black women writers, for example, she assigns students to write an autobiographical paragraph about an early racial memory, then to read it aloud as the others listen, thus affirming the uniqueness and value of each voice and creating a communal awareness of the diversity of the group’s experiences (hooks 1994: 84). Her “engaged pedagogy” is thus similar to the “freedom under guidance” implemented in John Dewey’s Laboratory School of Chicago in the late 1890s and early 1900s. It incorporates the dialogue, anchored instruction, and mentoring that Abrami (2015) found to be most effective in improving critical thinking skills and dispositions.

What is the relationship of critical thinking to problem solving, decision-making, higher-order thinking, creative thinking, and other recognized types of thinking? One’s answer to this question obviously depends on how one defines the terms used in the question. If critical thinking is conceived broadly to cover any careful thinking about any topic for any purpose, then problem solving and decision making will be kinds of critical thinking, if they are done carefully. Historically, ‘critical thinking’ and ‘problem solving’ were two names for the same thing. If critical thinking is conceived more narrowly as consisting solely of appraisal of intellectual products, then it will be disjoint with problem solving and decision making, which are constructive.

Bloom’s taxonomy of educational objectives used the phrase “intellectual abilities and skills” for what had been labeled “critical thinking” by some, “reflective thinking” by Dewey and others, and “problem solving” by still others (Bloom et al. 1956: 38). Thus, the so-called “higher-order thinking skills” at the taxonomy’s top levels of analysis, synthesis and evaluation are just critical thinking skills, although they do not come with general criteria for their assessment (Ennis 1981b). The revised version of Bloom’s taxonomy (Anderson et al. 2001) likewise treats critical thinking as cutting across those types of cognitive process that involve more than remembering (Anderson et al. 2001: 269–270). For details, see the Supplement on History .

As to creative thinking, it overlaps with critical thinking (Bailin 1987, 1988). Thinking about the explanation of some phenomenon or event, as in Ferryboat , requires creative imagination in constructing plausible explanatory hypotheses. Likewise, thinking about a policy question, as in Candidate , requires creativity in coming up with options. Conversely, creativity in any field needs to be balanced by critical appraisal of the draft painting or novel or mathematical theory.

What Is Critical Thinking? | Meaning & Examples

Critical thinking is the process of analyzing information logically and overcoming assumptions, biases, and logical fallacies. Developing critical thinking skills allows us to evaluate information as objectively as possible and reach well-founded conclusions.

Critical thinking example

Thinking critically is a crucial part of academic success, professional development, civic engagement, and personal decision-making.

Table of contents

What is critical thinking, why is critical thinking important, critical thinking strategies.

Critical thinking is the process of evaluating information and arguments in a disciplined and systematic way. It involves questioning assumptions, assessing evidence, and using logical reasoning to form well-reasoned judgments.

Key critical thinking skills:

• Avoiding unfounded assumptions
• Identifying and countering biases
• Recognizing and refuting logical fallacies

These practices enable us to make informed decisions, analyze evidence objectively, consider multiple perspectives, reflect on our own biases, and seek reliable sources.

Critical thinking is enhanced by the deliberate study of biases, logical fallacies, and the different forms of reasoning:

• Deductive reasoning: Drawing specific conclusions from general premises
• Inductive reasoning: Generalizing from specific observations
• Analogical reasoning: Drawing parallels between similar situations
• Abductive reasoning: Inferring the most likely explanation from incomplete evidence

When assessing sources, critical thinking requires evaluating several factors:

• Credibility: Check the author’s qualifications and the publication’s reputation.
• Evidence: Verify that the information is supported by data and references.
• Bias: Identify any potential biases or conflicts of interest.
• Currency: Ensure the information is up-to-date and relevant.
• Purpose: Understand the motivation behind the source and whether it aims to inform, persuade, or sell.

Critical thinking is crucial to decision-making and problem-solving in many domains of life. Social media disinformation and irresponsible uses of AI make it more important than ever to be able to distinguish between credible information and misleading or false content.

Developing critical thinking skills is an essential part of fostering independent thinking, allowing us to:

• Make informed decisions
• Solve complex problems
• Evaluate the logic of arguments

In the process of developing these skills, we become less susceptible to biases, fallacies, and propaganda.

Examples of critical thinking

Critical thinking is an essential part of consuming any form of media, including news, marketing, entertainment, and social media. Media platforms are commonly used to promote biased or manipulative messages, often in a subtle way.

Critical thinking in media example

A news segment claims eating chocolate daily improves cognitive function. After reading more about the research, you find the study had a small sample size and was funded by a chocolate company, indicating bias. This leads you to conclude the claim is unreliable.

Critical thinking is fundamental in logic, math, law, science, and other academic and professional domains. The scientific method is a quintessential example of systematized critical thinking.

Critical thinking in science example

• Formulate a hypothesis.
• Design experiments.
• Analyze data.
• Draw conclusions.
• Revise the hypothesis if necessary.

Academic research requires advanced critical thinking skills.

Critical thinking academic example

• Evaluating the methodology of each study to determine their reliability and validity
• Checking for potential biases, such as funding sources or conflicts of interest
• Comparing the sample sizes and demographics of the studies to understand the context of their findings
• Synthesizing the results, highlighting common trends and discrepancies, and considering the limitations of each study

Critical thinking enhances informed decision-making by equipping us to recognize biases, identify logical fallacies, evaluate evidence, consider alternative perspectives, and learn to identify credible sources.

Key strategies:

• Recognize biases.
• Identify logical fallacies.
• Evaluate sources and evidence.
• Consider alternative perspectives.

critical thinking , in educational theory, mode of cognition using deliberative reasoning and impartial scrutiny of information to arrive at a possible solution to a problem. From the perspective of educators, critical thinking encompasses both a set of logical skills that can be taught and a disposition toward reflective open inquiry that can be cultivated . The term critical thinking was coined by American philosopher and educator John Dewey in the book How We Think (1910) and was adopted by the progressive education movement as a core instructional goal that offered a dynamic modern alternative to traditional educational methods such as rote memorization.

Critical thinking is characterized by a broad set of related skills usually including the abilities to

• break down a problem into its constituent parts to reveal its underlying logic and assumptions
• recognize and account for one’s own biases in judgment and experience
• collect and assess relevant evidence from either personal observations and experimentation or by gathering external information
• adjust and reevaluate one’s own thinking in response to what one has learned
• form a reasoned assessment in order to propose a solution to a problem or a more accurate understanding of the topic at hand

Theorists have noted that such skills are only valuable insofar as a person is inclined to use them. Consequently, they emphasize that certain habits of mind are necessary components of critical thinking. This disposition may include curiosity, open-mindedness, self-awareness, empathy , and persistence.

Although there is a generally accepted set of qualities that are associated with critical thinking, scholarly writing about the term has highlighted disagreements over its exact definition and whether and how it differs from related concepts such as problem solving . In addition, some theorists have insisted that critical thinking be regarded and valued as a process and not as a goal-oriented skill set to be used to solve problems. Critical-thinking theory has also been accused of reflecting patriarchal assumptions about knowledge and ways of knowing that are inherently biased against women.

Dewey, who also used the term reflective thinking , connected critical thinking to a tradition of rational inquiry associated with modern science. From the turn of the 20th century, he and others working in the overlapping fields of psychology , philosophy , and educational theory sought to rigorously apply the scientific method to understand and define the process of thinking. They conceived critical thinking to be related to the scientific method but more open, flexible, and self-correcting; instead of a recipe or a series of steps, critical thinking would be a wider set of skills, patterns, and strategies that allow someone to reason through an intellectual topic, constantly reassessing assumptions and potential explanations in order to arrive at a sound judgment and understanding.

In the progressive education movement in the United States , critical thinking was seen as a crucial component of raising citizens in a democratic society. Instead of imparting a particular series of lessons or teaching only canonical subject matter, theorists thought that teachers should train students in how to think. As critical thinkers, such students would be equipped to be productive and engaged citizens who could cooperate and rationally overcome differences inherent in a pluralistic society.

Beginning in the 1970s and ’80s, critical thinking as a key outcome of school and university curriculum leapt to the forefront of U.S. education policy. In an atmosphere of renewed Cold War competition and amid reports of declining U.S. test scores, there were growing fears that the quality of education in the United States was falling and that students were unprepared. In response, a concerted effort was made to systematically define curriculum goals and implement standardized testing regimens , and critical-thinking skills were frequently included as a crucially important outcome of a successful education. A notable event in this movement was the release of the 1980 report of the Rockefeller Commission on the Humanities that called for the U.S. Department of Education to include critical thinking on its list of “basic skills.” Three years later the California State University system implemented a policy that required every undergraduate student to complete a course in critical thinking.

Critical thinking continued to be put forward as a central goal of education in the early 21st century. Its ubiquity in the language of education policy and in such guidelines as the Common Core State Standards in the United States generated some criticism that the concept itself was both overused and ill-defined. In addition, an argument was made by teachers, theorists, and others that educators were not being adequately trained to teach critical thinking.

A SUPER-STREAMLINED CONCEPTION OF CRITICAL THINKING Robert H. Ennis, 6/20/02

Assuming that critical thinking is reasonable reflective thinking focused on deciding what to believe or do, a critical thinker:

1. Is open-minded and mindful of alternatives 2. Tries to be well-informed 3. Judges well the credibility of sources 4. Identifies conclusions, reasons, and assumptions 5. Judges well the quality of an argument, including the acceptability of its reasons, assumptions, and evidence 6. Can well develop and defend a reasonable position 7. Asks appropriate clarifying questions 8. Formulates plausible hypotheses; plans experiments well 9. Defines terms in a way appropriate for the context 10. Draws conclusions when warranted, but with caution 11. Integrates all items in this list when deciding what to believe or do

Critical Thinkers are disposed to:

1. Care that their beliefs be true, and that their decisions be justified; that is, care to "get it right" to the extent possible. This includes the dispositions to

a. Seek alternative hypotheses, explanations, conclusions, plans, sources, etc., and be open to them b. Endorse a position to the extent that, but only to the extent that, it is justified by the information that is available c. Be well informed d. Consider seriously other points of view than their own

2. Care to present a position honestly and clearly, theirs as well as others'. This includes the dispositions to

14. Be sensitive to the feelings, level of knowledge, and degree of sophistication of others

15. Employ appropriate rhetorical strategies in discussion and presentation (orally and in writing), including employing and reacting to "fallacy" labels in an appropriate manner.

Examples of fallacy labels are "circularity," "bandwagon," "post hoc," "equivocation," "non sequitur," and "straw person."

Dewey, John Critical thinking is "active, persistent, and careful consideration of any belief or supposed form of knowledge in the light of the grounds that support it and the further conclusions to which it tends (Dewey 1933: 118)."

Glaser (1) an attitude of being disposed to consider in a thoughtful way the problems and subjects that come within the range of one's experiences, (2) knowledge of the methods of logical inquiry and reasoning, and (3) some skill in applying those methods. Critical thinking calls for a persistent effort to examine any belief or supposed form of knowledge in the light of the evidence that supports it and the further conclusions to which it tends. (Glaser 1941, pp. 5-6).

Abilities include: "(a) to recognize problems, (b) to find workable means for meeting those problems, (c) to gather and marshal pertinent information, (d) to recognize unstated assumptions and values, (e) to comprehend and use language with accuracy, clarity and discrimination, (f) to interpret data, (g) to appraise evidence and evaluate statements, (h) to recognize the existence of logical relationships between propositions, (i) to draw warranted conclusions and generalizations, (j) to put to test the generalizations and conclusions at which one arrives, (k) to reconstruct one's patterns of beliefs on the basis of wider experience; and (l) to render accurate judgments about specific things and qualities in everyday life." (p.6)

MCC General Education Initiatives "Critical thinking includes the ability to respond to material by distinguishing between facts and opinions or personal feelings, judgments and inferences, inductive and deductive arguments, and the objective and subjective. It also includes the ability to generate questions, construct, and recognize the structure of arguments, and adequately support arguments; define, analyze, and devise solutions for problems and issues; sort, organize, classify, correlate, and analyze materials and data; integrate information and see relationships; evaluate information, materials, and data by drawing inferences, arriving at reasonable and informed conclusions, applying understanding and knowledge to new and different problems, developing rational and reasonable interpretations, suspending beliefs and remaining open to new information, methods, cultural systems, values and beliefs and by assimilating information."

Nickerson, Perkins and Smith (1985) "The ability to judge the plausibility of specific assertions, to weigh evidence, to assess the logical soundness of inferences, to construct counter-arguments and alternative hypotheses."

Moore and Parker , Critical Thinking Critical Thinking is "the careful, deliberate determination of whether we should accept, reject, or suspend judgment about a claim, and the degree of confidence with which we accept or reject it."

Delphi Report "We understand critical thinking to be purposeful, self-regulatory judgment which results in interpretation, analysis, evaluation, and inference, as well as explanation of the evidential, conceptual, methodological, criteriological, or contextual considerations upon which that judgment is based. CT is essential as a tool of inquiry. As such, CT is a liberating force in education and a powerful resource in one's personal and civic life. While not synonymous with good thinking, CT is a pervasive and self-rectifying human phenomenon. The ideal critical thinker is habitually inquisitive, well-informed, trustful of reason, open-minded, flexible, fair-minded in evaluation, honest in facing personal biases, prudent in making judgments, willing to reconsider, clear about issues, orderly in complex matters, diligent in seeking relevant information, reasonable in the selection of criteria, focused in inquiry, and persistent in seeking results which are as precise as the subject and the circumstances of inquiry permit. Thus, educating good critical thinkers means working toward this ideal. It combines developing CT skills with nurturing those dispositions which consistently yield useful insights and which are the basis of a rational and democratic society."

A little reformatting helps make this definition more comprehensible:

We understand critical thinking to be purposeful, self-regulatory judgment which results in

• interpretation

as well as explanation of the

• methodological
• criteriological

considerations upon which that judgment is based.

Francis Bacon (1605) "For myself, I found that I was fitted for nothing so well as for the study of Truth; as having a mind nimble and versatile enough to catch the resemblances of things … and at the same time steady enough to fix and distinguish their subtler differences; as being gifted by nature with desire to seek, patience to doubt, fondness to meditate, slowness to assert, readiness to consider, carefulness to dispose and set in order; and as being a man that neither affects what is new nor admires what is old, and that hates every kind of imposture."

A shorter version is "the art of being right."

Or, more prosaically: critical thinking is "the skillful application of a repertoire of validated general techniques for deciding the level of confidence you should have in a proposition in the light of the available evidence."

Critical thinking refers to the ability to analyze information objectively and make a reasoned judgment. It involves the evaluation of sources, such as data, facts, observable phenomena, and research findings.

Good critical thinkers can draw reasonable conclusions from a set of information, and discriminate between useful and less useful details to solve problems or make decisions. These skills are especially helpful at school and in the workplace, where employers prioritize the ability to think critically. Find out why and see how you can demonstrate that you have this ability.

Examples of Critical Thinking

The circumstances that demand critical thinking vary from industry to industry. Some examples include:

• A triage nurse analyzes the cases at hand and decides the order by which the patients should be treated.
• A plumber evaluates the materials that would best suit a particular job.
• An attorney reviews the evidence and devises a strategy to win a case or to decide whether to settle out of court.
• A manager analyzes customer feedback forms and uses this information to develop a customer service training session for employees.

Why Do Employers Value Critical Thinking Skills?

Employers want job candidates who can evaluate a situation using logical thought and offer the best solution.

Someone with critical thinking skills can be trusted to make decisions independently, and will not need constant handholding.

Hiring a critical thinker means that micromanaging won't be required. Critical thinking abilities are among the most sought-after skills in almost every industry and workplace. You can demonstrate critical thinking by using related keywords in your resume and cover letter and during your interview.

How to Demonstrate Critical Thinking in a Job Search

If critical thinking is a key phrase in the job listings you are applying for, be sure to emphasize your critical thinking skills throughout your job search.

Add Keywords to Your Resume

You can use critical thinking keywords (analytical, problem solving, creativity, etc.) in your resume. When describing your work history, include top critical thinking skills that accurately describe you. You can also include them in your resume summary, if you have one.

For example, your summary might read, “Marketing Associate with five years of experience in project management. Skilled in conducting thorough market research and competitor analysis to assess market trends and client needs, and to develop appropriate acquisition tactics.”

Mention Skills in Your Cover Letter

Include these critical thinking skills in your cover letter. In the body of your letter, mention one or two of these skills, and give specific examples of times when you have demonstrated them at work. Think about times when you had to analyze or evaluate materials to solve a problem.

Show the Interviewer Your Skills

You can use these skill words in an interview. Discuss a time when you were faced with a particular problem or challenge at work and explain how you applied critical thinking to solve it.

Some interviewers will give you a hypothetical scenario or problem, and ask you to use critical thinking skills to solve it. In this case, explain your thought process thoroughly to the interviewer. He or she is typically more focused on how you arrive at your solution rather than the solution itself. The interviewer wants to see you analyze and evaluate (key parts of critical thinking) the given scenario or problem.

Of course, each job will require different skills and experiences, so make sure you read the job description carefully and focus on the skills listed by the employer.

Top Critical Thinking Skills

Keep these in-demand skills in mind as you refine your critical thinking practice —whether for work or school.

Part of critical thinking is the ability to carefully examine something, whether it is a problem, a set of data, or a text. People with analytical skills can examine information, understand what it means, and properly explain to others the implications of that information.

• Asking Thoughtful Questions
• Data Analysis
• Interpretation
• Questioning Evidence
• Recognizing Patterns

Communication

Often, you will need to share your conclusions with your employers or with a group of classmates or colleagues. You need to be able to communicate with others to share your ideas effectively. You might also need to engage in critical thinking in a group. In this case, you will need to work with others and communicate effectively to figure out solutions to complex problems.

• Active Listening
• Collaboration
• Explanation
• Interpersonal
• Presentation
• Verbal Communication
• Written Communication

Critical thinking often involves creativity and innovation. You might need to spot patterns in the information you are looking at or come up with a solution that no one else has thought of before. All of this involves a creative eye that can take a different approach from all other approaches.

• Flexibility
• Conceptualization
• Imagination
• Drawing Connections
• Synthesizing

Open-Mindedness

To think critically, you need to be able to put aside any assumptions or judgments and merely analyze the information you receive. You need to be objective, evaluating ideas without bias.

• Objectivity
• Observation

Problem-Solving

Problem-solving is another critical thinking skill that involves analyzing a problem, generating and implementing a solution, and assessing the success of the plan. Employers don’t simply want employees who can think about information critically. They also need to be able to come up with practical solutions.

Philosophy Behind Critical Thinking: A Concise Overview

The philosophy behind critical thinking delves into the deeper understanding of what it means to think critically and to develop the ability to reason, analyze, and evaluate information in a structured and systematic manner. Critical thinking has intricate connections with philosophy, mainly because it originated from ancient philosophical teachings. At its core, the concept of critical thinking is rooted in the Socratic method of questioning, which emphasizes the importance of inquiry and rational thinking as a means to achieve knowledge.

Key Takeaways

Understanding critical thinking.

Definition and Process

Critical thinking is the ability to think clearly and rationally about what to do or what to believe. It involves engaging in reflective and independent thinking . To understand the logical connections between ideas, one needs to identify, construct, and evaluate arguments.

Logic, Reason, Rationality

Logic, reason, and rationality are essential components of critical thinking. Logic refers to the systematic approach to reasoning and validating claims through principles and rules. Reasoning, on the other hand, is the process of drawing conclusions based on logic, evidence, and assumptions. Rationality encompasses the use of logic and reason to make well-informed decisions, judgments, and evaluations.

Strategies and Patterns

Justification and argumentation.

Justification and argumentation play a crucial role in critical thinking. Justification refers to providing reasons or evidence in support of a claim, while argumentation involves constructing and evaluating arguments . Both justification and argumentation require logical reasoning, analysis of evidence, and clear communication of ideas.

Clarity and Reflection

Clarity is essential for effective critical thinking. This entails expressing ideas and arguments in a clear, concise, and organized manner. Furthermore, critical thinkers must also engage in reflection — the process of examining their own thought processes, assumptions, and biases. Reflecting on one’s beliefs and values helps individuals refine their thinking and develop a more nuanced understanding of the world around them.

In conclusion, understanding critical thinking involves exploring its definition, process, and key components, such as logic, reason, rationality, strategies, patterns, justification, argumentation, clarity, and reflection. By cultivating a strong foundation in these areas, individuals can develop their ability to think critically and make well-informed decisions in various aspects of life.

Psychological Approach to Critical Thinking

Cognition and Pattern Recognition

Bias and judgments.

Another aspect of the psychological approach to critical thinking is the examination of biases and judgments. Bias refers to the systematic errors or distortions in human reasoning that can arise from emotions, beliefs, or external factors. When individuals possess a strong bias, it can impede their ability to think critically and accurately evaluate information. By being aware of these biases and actively seeking to minimize their influence, one can improve their critical thinking skills and make more accurate judgments.

Problem-Solving and Decision-Making

Philosophical groundings, roots of critical thought.

The roots of critical thought can be traced back to ancient Greek philosophy, particularly the ideas developed by Socrates, Plato, and Aristotle. In their teachings, these philosophers emphasized the importance of questioning and examining beliefs, seeking evidence, and evaluating arguments logically. Through these pursuits, they laid a strong foundation for the development of critical thinking in modern times.

Major Philosophers and Approaches

Informal logic and its importance.

Informal logic plays a crucial role in critical thinking as it concerns the principles and methods used to analyze everyday arguments and reasoning beyond the scope of formal logic. It complements formal logic, which deals strictly with logical systems and symbols. Informal logic helps individuals assess the validity, soundness, and context of arguments encountered in daily life. By honing their skills in informal logic, individuals can become better critical thinkers and more adept at navigating complex situations and decision-making processes.

Critical Thinking in Cultural and Social Context

Race and gender perspectives.

Critical thinking is a universal skill that transcends cultural and social boundaries. However, it is essential to consider the impact of race and gender on the development and exercise of critical thinking skills. People from marginalized groups may experience unique challenges and perspectives that influence their critical thinking abilities. For example, in a cross-cultural study examining critical thinking among nurse scholars in Thailand and the United States, distinctive perspectives on critical thinking were observed due to cultural differences. Understanding the intersections of race, gender, and critical thinking can help create more inclusive education and workplace environments that foster critical thinking for everyone.

Critical Thinking in a Democratic Society

In a democratic society, critical thinking plays a crucial role in informed decision-making, civic engagement, and open discussion. The healthy functioning of a democracy relies on the citizens’ capacity to discern reliable information, assess arguments, and make rational choices. According to the Stanford Encyclopedia of Philosophy , critical thinking includes abilities and dispositions that lead individuals to think critically when appropriate. Developing these skills allows members of democratic societies to engage in productive debates, evaluate policies, and hold leaders accountable.

Culture, Society, and Critical Thinking

Role of critical thinking in education, aims of education.

The primary aim of education is to foster the development of individuals’ cognitive capabilities, empowering them to grow into confident, knowledgeable and discerning adults. Critical thinking plays a significant role in education as it helps students acquire and apply knowledge more effectively, by analyzing, evaluating, and synthesizing information from diverse sources in a systematic manner, leading to more accurate and informed decisions.

Skills Development

Classroom activities focused on critical thinking are essential to help students develop a systematic approach to problem-solving and sharpen their analytical skills. Practical tasks, like debates, group discussions, case studies, or role plays, can be employed to engage students in active learning, thus enhancing their critical thought processes.

Standardized Tests vs. Critical Thought

While standardized tests have dominated the contemporary education system, there is growing concern regarding their effectiveness in promoting critical thinking. Some argue that standardized tests prioritize the acquisition of specific knowledge over the development of essential skills and abilities, leading to an education that is more focused on rote memorization than meaningful learning.

Importance of Open-Mindedness and Skepticism

Being skeptical vs. being cynical.

It is essential to understand the difference between being skeptical and being cynical. Skepticism in critical thinking involves questioning assertions and assumptions, seeking evidence, and evaluating arguments from a neutral, objective viewpoint. On the other hand, cynicism is a distrustful attitude, where one assumes negative intentions or outcomes.

Traits of an Open-Minded Thinker

Open-mindedness is an essential trait for critical thinkers. Some key characteristics of an open-minded thinker include:

Role of Curiosity and Empathy in Critical Thinking

Empathy, on the other hand, permits critical thinkers to comprehend and appreciate different perspectives by placing themselves in others’ shoes. An empathetic approach contributes to open-mindedness and cultivates a sense of humility, recognizing that individuals may hold contrasting opinions based on personal experiences or beliefs. The combination of curiosity and empathy enhances critical thinking by promoting a more inclusive and nuanced understanding of complex issues and scenarios.

Critical thinking equips individuals with the tools necessary to think carefully with clarity, depth, precision, accuracy, and logic 3 . It has applications across various domains, such as science, where great scientists like Albert Einstein have benefited from critical thinking skills to discover groundbreaking concepts.

5 Critical Pedagogy: Challenging Bias and Creating Inclusive Classrooms

Introduction.

Regardless of the type of library you work in, your learners will come from varied backgrounds, identities, and life experiences, and will bring different interests and educational needs to the classroom. These experiences shape how learners experience the classroom, the content, and the learning activities, and ultimately impact what they learn and how they use that knowledge. As instructors, we need not only to recognize these differences and how they influence learning but also acknowledge and honor the richness of experience our learners bring. We need to create an inclusive classroom environment where everyone feels welcome and valued, and where our content is relevant to our learners’ diverse identities and interests.

In order to be effective in this role, we must better understand how existing educational, social, and political systems shape our learners’ experiences from their earliest moments and continue to influence what and how they learn inside and outside of the classroom through the rest of their lives. We must recognize how bias has impacted and continues to impact both our learners’ and our own experiences, and develop culturally competent and inclusive practices in order to mitigate bias in the classroom and interact effectively with learners from varied cultural backgrounds.

Critical pedagogy provides a theoretical framework to examine issues of power in the classroom, and to surface and challenge the biases and oppressive structures that can undermine learning and alienate students. Inclusive teaching offers strategies for translating that theoretical knowledge into action. This chapter begins with a brief overview of critical pedagogy, followed by an examination of some of the biases critical pedagogy uncovers and how those biases can impact the work we do as instructors. Next, the chapter presents strategies for mitigating bias, improving our cultural competence, and creating inclusive classrooms where all learners are able to engage with relevant content and effective pedagogies. Chapter 6 extends the discussion of inclusion to address specific issues of accessibility and universal design for learners with disabilities.

Critical Pedagogy

As discussed briefly in Chapter 3, social constructivists in particular recognize that learners’ cultures, including shared values, behaviors, and beliefs, shape their knowledge. However, no society is made up of a single, monolithic culture; rather, different communities reflect different values and beliefs, and encourage and discourage different behaviors. Political, social, and educational systems tend to reflect the dominant culture, and over time the values, behaviors, and beliefs associated with that culture become so ingrained as to be invisible. Those living within the dominant culture do not recognize it as a system but simply see it as “normal,” and anything outside of that system is “other” than normal. Some educational theorists recognized that these differences have a profound impact on education.

Bourdieu (see, e.g., Bourdieu & Passeron, 2000) and Freire (2000), for instance, saw that traditional educational systems tended to reflect and favor the experiences of children from wealthy families. Because these children understood that system and saw themselves reflected in it, they thrived and were successful, while children from poorer families struggled. Since the dominant systems are essentially invisible, those in power tend to attribute the challenges faced by marginalized individuals as inherent to the person. In other words, if a child from a poor family struggles to learn to read, teachers will often assume the issue is with the child’s innate ability to learn, rather than recognize that the child might not have had the same preliteracy experiences and current support systems that other children have. Because they do not recognize the root issue, these educational models tend to replicate rather than challenge the existing systems, so learners from the dominant culture continue to succeed while those from marginalized communities continue to struggle, a phenomenon that Bourdieu refers to as cultural reproduction. While earlier theorists tended to focus mostly on the impact of economic disparities in education, other writers and educators like bell hooks, Henry Giroux, and Ileana Jiménez have applied feminist, queer, and critical race theory to examine how existing classroom power structures marginalize women, people of color, individuals who identify as LGBTQIA+, and other learners as well.

Importantly, critical pedagogy does not end with theory but rather focuses on praxis, or translating knowledge into action. Critical pedagogy sees education as a tool for empowerment, a place where learners develop the knowledge and skills they need to undo oppressive structures and achieve liberation (Freire, 2000; Tewell, 2015). Unlike the traditional “banking” model of education that positions learners as passive recipients of information, in a classroom guided by critical pedagogy, learners engage with problems that are personally meaningful and are active agents in their own education, and through that education gain agency to enact change in the world beyond the classroom (Elmborg, 2006; Freire, 2000; Tewell, 2015).

Critical pedagogy informs the critical approaches to information literacy discussed in Chapter 2, which urge us to move away from a skills-based, teacher-centered approach to information literacy toward one that questions dominant information structures and adopts student-centered teaching methods. Building on the ideas of agency and empowerment, critical information literacy encourages learners to see themselves as part of the “scholarly conversation” and as creators of information, rather than just consumers, and provides them with ways to recognize and challenge dominant powers within the current systems of creating, sharing, and evaluating information. Thus, for instructors, critical pedagogy pushes us to surface power dynamics in the classroom and the larger communities in which our learners live, and to reflect on how our own culture and biases color our approach to the classroom. In doing so, it offers a model for a more inclusive teaching practice.

Bias in the Classroom

We all have bias. These biases might be based on gender, race or ethnicity, class, religion, sexual orientation, gender identity, body type, or other elements of people’s personal identity. In some cases, we may be aware that we have a bias, while in other cases, we hold unconscious biases that we have unwittingly picked up over the course of our lifetime. Banaji and Greenwald (2013) show that our unconscious biases are particularly pernicious because we are unaware of the effect they have on our thoughts and actions, resulting in discriminatory judgments and behaviors that are automatic and hard to recognize. For example, research shows that when given résumés with equivalent qualifications from applicants with stereotypically white names and stereotypically Black names, search committees will favor applicants with stereotypically white names (Bertrand & Mullainathan, 2003) and that orchestras have historically favored men over women in auditions (Goldin & Rouse, 2000). Unconscious bias also affects library services. Shachaf and Horowitz (2006) found differences in librarians’ replies to email reference queries based on the patron’s perceived ethnicity and religious affiliation, including the time taken to reply, length and quality of answers, and the use of welcoming, professional greetings and conclusions. These examples demonstrate one of Banaji and Greenwald’s important findings–that hidden biases result in acts of commission, such as favoring men or whites in hiring, as well as acts of omission, such as providing less thorough service to some patrons.

It can be uncomfortable and even challenging to recognize our own bias. As Sue (2010a) notes, most people “see themselves as fair-minded individuals who would never consciously discriminate” and “their self-image of being ‘a good moral human being’ is assailed if they realize and acknowledge that they possess biased thoughts, attitudes and feelings.” As we grapple with our own biases, it can be helpful to remember that our brains evolved to develop heuristics that allow us to function effectively and safely in our environment. These heuristics often operate at an unconscious level; if you have ever seen a snake and instinctively jumped back even before you could assess whether the snake was venomous, you have experienced an unconscious heuristic that told you snakes are dangerous. Unfortunately, unconscious thoughts and biases influence how we react to people as well, particularly when we perceive those people as “different” from ourselves. If we want to be fair-minded, rational people, it is essential that we identify and reflect on our unconscious biases, including recognizing how our society shapes and influences those biases, in order to mitigate the effect they have on our thoughts and actions (Banaji and Greenwald, 2013). Activity 5.1 provides an opportunity to learn more about unconscious biases you may hold.

Activity 5.1: Take an Implicit Bias Test

As part of its research on implicit bias, Project Implicit at Harvard University offers tests that attempt to measure personal biases. While these tests are not perfect measures, they offer a starting point for reflecting on how we might be impacted by unconscious bias. Visit Project Implicit and try one or more of the available tests.

Questions for Reflection and Discussion:

• How did you feel about your results? Were you surprised or uncomfortable? Did other feelings emerge?
• If your test results revealed a personal bias, how might that bias affect your work in the classroom? What strategies could you use to mitigate this bias and deliver high-quality instruction to all your learners?

One manifestation of bias is microaggressions, which Sue (2010a) defines as “the everyday verbal, nonverbal, and environmental slights, snubs, or insults, whether intentional or unintentional, which communicate hostile, derogatory, or negative messages to target persons based solely upon their marginalized group membership.” Microaggressions may be aimed at women, people of color, individuals who identify (or are perceived) as LGBTQIA+, and people with disabilities, among others. Microaggressions come in many forms, including verbal (e.g., “Where are you from?” which implies a person of color must be a foreigner; telling a woman to smile), nonverbal (e.g., clutching one’s purse more tightly or crossing the street around a person of color), or environmental (e.g., Native American mascots) (Sue, 2010b). While microaggressions may appear minor, they create hostile classroom environments, perpetuate stereotype threat, lower workplace productivity, and cause mental and physical health problems (Sue et al., 2009, p. 183).

Because microaggressions often reflect our unconscious biases, they can be hard to eliminate. Princing (2019) notes that when we first meet someone new, we tend to notice what makes them different from us. She recommends we reflect on those thoughts and question any beliefs or stereotypes that may accompany them. The Reinert Center for Transformative Teaching and Learning (n.d.) also recommends that instructors reflect on their assumptions and expectations as a first step to avoid committing microaggressions. For example, an instructor who assumes that learners from first-generation or lower socioeconomic backgrounds are less prepared for college might make a comment to that effect in the classroom, making students hesitant to attend office hours lest they confirm the instructor’s negative belief. Additional strategies instructors can use:

• Resist the myth of color blindness. Unconscious bias makes it difficult to be truly colorblind. In addition, claims of color blindness obscure structural disadvantages and the very real differences in the experiences of people from marginalized groups (Princing, 2019).
• Believe the stories of people from marginalized groups. We can learn more about everyday bias by listening to and learning from the stories of individuals who have firsthand experience with bias. We must take care not to dismiss those stories as exaggerations, misunderstandings, or isolated incidents.
• Do not ask students to speak for their entire racial or culture group. As noted elsewhere in this chapter, learners from the same broad cultural group will not necessarily share all of the same values, beliefs, and understandings, and students may not feel capable of speaking for the experience of others (Reinert Center, n.d.). In addition, singling out learners in this way can make it appear that the instructor sees them as a one-dimensional representative of a particular identity, rather than as an individual bringing varied strengths, interests, and experiences to the classroom.
• Assume groups you are talking about are represented in the classroom. Treating every classroom interaction as if we were speaking with a member of the group under discussion can remind us to choose our words with care (Reinert Center, n.d.).
• Remain open to learning about microaggressions and yourself. While it is natural to feel defensive when others point out that we have said something problematic or offensive, we can approach such instances as learning opportunities.

In addition to recognizing the role that bias might play in our own actions, instructors should be aware that students will bring their own biases to the classroom. These biases will affect how learners understand and interact with instructional content, peers, and instructors, and instructors should be attentive to instances where learners commit microaggressions against one another. Microaggressions can be awkward and even challenging to address, especially if they were framed as a compliment (e.g., “You speak English so well”) or reflect commonly accepted stereotypes. Offenders may be unaware of the offense they have caused and because they did not intend to offend others, may be reluctant to accept responsibility for having done so. However, it is important to address such events clearly and promptly. Sue et al. (2019, p. 134) note that when microaggressions occur, small interventions by allies and bystanders have a “profound positive effect in creating an inclusive and welcoming environment” and discouraging further microaggressions. Strategies for addressing microaggressions in the classroom include:

• Make the “invisible” visible.  Create awareness by naming the microaggression with statements such as “I think that’s a stereotype I just heard” (Sue et al., 2019, p. 136).
• Disarm the microaggression. Statements such as “I don’t agree” or “I don’t see it that way” and actions such as shaking one’s head communicate to the perpetrator and others that the microaggression is not acceptable (Sue et al., 2019, p. 136).
• Take an educational, nonpunitive approach. Turn microaggressions into teachable moments by asking learners to reflect on their assumptions (Center for Teaching and Learning, n.d., p. 11). Phrases like “it sounds like you think” or “Could there be another way to look at this?” can prompt speakers to identify and question their unconscious biases (Gonzaga et al., 2019). Ferguson (2015) suggests we approach microaggressions in the spirit of “calling in” rather than “calling out.”
• Redirect. When students are asked to speak for all members of their racial or cultural group, we can redirect the conversation with statements such as “Let’s open this question up to others” (Gonzaga et al., 2019).
• Use “I” statements. The use of “I” statements such as “I felt uncomfortable when you said . . . ” communicate impact while minimizing blame (Gonzaga et al., 2019).
• Discuss intent versus impact. Instructors can use statements like “I know you meant to be funny, but you hurt . . . ” to help learners recognize the impact of something they said. If learners struggle with the idea that they may have offended or harmed someone despite not intending to cause offense, instructors can use metaphors such as bumping someone in the grocery store or causing a car accident to explain the difference between intent and impact (and the need to make amends).
• Rewind. Sometimes microaggressions happen so quickly, the conversation moves on before they are addressed. Statements like “I’d like to revisit something that was said earlier” allow us to step back and address these microaggressions ( Gonzaga et al., 2019).

Another manifestation of bias can be “othering,” or treating the history and experiences of white, middle-class, heterosexual, cisgender, able-bodied people as universal or the norm, while presenting the history and experiences of other groups as unusual, exceptional, or only of interest to members of those communities. For example, displaying books by Black authors in February, but not at other times, sends an implicit message that the history of America is the actions and accomplishments of whites and that the accomplishments of others are of limited value or interest. While special displays and programs are an important way to recognize and support events like Black History Month, Women’s History Month, and Pride Month, librarians should also integrate materials by individuals of color, women, and LGBTQIA+ authors into displays year-round.

In some cases, the systems that are foundational to libraries treat selected groups as the other. For example, the Dewey Decimal System reserves 200-289 for topics related to Christianity and the Bible, leaving only the 290s for all other religions; Schingler (2015) points out that this reflects an underlying assumption that Christianity not only has more to say on theological topics, what it has to say is more valuable. Library of Congress Subject Headings (LCSH) are notoriously problematic in their treatment of women and people of color (Berman, 1969, 1993; Drabinski, 2008; Knowlton, 2005). The presence of subject headings such as “women astronauts” and “African American business enterprises” reveals an assumption that these professions are for white men and that the presence of others is unusual or remarkable, while subject headings that utilize biased terminology, such as “illegal aliens,” send a message about who belongs in America.

These instances of bias and othering can create barriers to information seeking. Howard and Knowlton (2018) point out that Library of Congress Classification distributes materials related to African American and LGBTQIA+ issues throughout the collection, making browsing or even grasping the scope of the topic challenging for researchers. Even when controlled vocabulary uses neutral terminology, the accompanying thesauri can obscure topics for patrons trying to identify the database’s preferred subject heading. For example, a search for “queer” in the ERIC thesaurus returns “the term(s) you entered could not be found” with no suggestions for next steps ( ERIC uses the subject heading “homosexuality”). In comparison, a search for “queer” in the thesaurus for PubMed takes one to the preferred subject heading, “sexual and gender minorities,” along with notes about how the term is applied and related/narrower terms.

As part of creating inclusive classrooms, we must be aware of the ways in which library systems and spaces can “other” marginalized groups, and take steps to improve equity and inclusion in our spaces and collections. For example, when creating lessons, we can plan search examples that reflect the diversity of our community and learners’ interests. As appropriate, we can surface and acknowledge problematic practices, and engage students in a dialogue about the impact of those practices and how they might be changed. Integrating diversity into curricular content is addressed in more detail later in this chapter.

Deficit-Based Thinking

Learners, by their very nature, come to our libraries and classrooms with gaps in their knowledge and skills. Oftentimes, instructors seek out research that will help them identify these gaps in order to develop relevant content. While this research can provide valuable guidance for instructors, it is sometimes framed solely in terms of what learners are lacking and can lead us to focus exclusively on students’ weaknesses, an approach termed deficit-based thinking.

Increasingly, educators are taking an asset-based approach that recognizes and builds on the strengths students bring to the classroom (Heinbach, 2019; Ilett, 2019; Kocevar-Weidinger et al., 2019; Matteson & Gersch, 2019; Tewell, 2020). For example, research on returning adult learners may show that they lack up-to-date research and citation skills, framing this as a problem that will hinder academic success. An asset-based approach recognizes that adult learners, by virtue of having spent time in the workforce, bring valuable life experience that can enrich classroom discussions, along with strong collaborative and interpersonal skills developed in the workplace. In addition, adult learners tend to have clear educational and career goals and are highly motivated to develop the knowledge and skills they need to succeed in higher education. As another example, Kocevar-Weidinger et al. (2019) show that despite the stereotype that first-year college students lack research skills, they actually have extensive everyday research experience that can serve as a starting point for academic information literacy instruction.

Sometimes things characterized as weaknesses or deficits are in fact strengths if we recast our narrative. For instance, research on first-generation students may focus on the challenges they encounter because their families are unable to advise them on how to navigate the academic and social aspects of college. Research also shows that first-generation undergraduate students are less likely to use campus support services (Longwell-Grice et al., 2016; Portnoi & Kwong, 2011). An asset-based approach recognizes that families of first-generation students are often very supportive of their students’ academic endeavors and, if given information about support services on campus, will recommend their students take advantage of such services. Thus, while they lack firsthand knowledge of higher education, family members can be a conduit to connecting first-generation students to campus resources. Activity 5.2 asks you to think more deeply about asset-based approaches.

Activity 5.2: Reflecting on Asset-Based Thinking

Individually or with a group of classmates, select a group of learners you might work with, such as recent immigrants, English-language learners, international students, or older adults.

• What gaps in knowledge or skills are typically ascribed to this group? Are these viewed as simple gaps or as deficits?
• What strengths will this group of learners bring to the classroom?
• How could you use an asset-based approach to build on these strengths in designing instruction?

Cultural Competency

Cultural competency is the ability to work effectively with people from varied cultural backgrounds. Cultural competency is an essential skill for librarians; it prepares us to recognize barriers to information use, to work with colleagues and patrons of diverse backgrounds, and to develop culturally responsive services and programs (Cooke et al., 2017; Kim & Sin, 2006; Morris, 2007; Overall, 2009). Instructors who are culturally competent understand how culture influences teaching and learning, and are able to engage learners from diverse backgrounds in the classroom.

Cultural differences can emerge in our classrooms in numerous ways. For example, contemporary American classrooms tend to be student-centered; students are expected to ask questions during lectures, discuss ideas and even disagree with instructors and peers, and engage in self-directed learning activities. In contrast, some cultures value teacher-centered classrooms where learners are expected to listen respectfully as teachers share their expertise. International students and recent immigrants who are accustomed to teacher-centered instruction may be uncomfortable during discussions and student-led activities and may even feel instructors are abdicating their responsibility to share expertise. They may also be reluctant to “bother” the instructor by asking questions or admitting they did not understand something. Culturally competent instructors can attend to these differences by interspersing discussion and active learning with direct instruction, encouraging questions and participation in discussions, and explaining how the planned activities support learning. In addition, librarians can create more culturally inclusive classrooms by:

• Speaking slowly and clearly, especially when working with learners from different cultures and language backgrounds.
• Avoiding slang, idioms, and sarcasm, none of which translates well across cultures, and using humor judiciously.
• Avoiding library jargon, which is likely to be unfamiliar to international students and recent immigrants, as well as to novice learners in general.
• Respecting cross-cultural rules for personal space and touching.
• Making expectations for participation explicit.

Cultural differences may surface in surprising ways. Bunner (2017, p. 43) provides an example of a student who got in trouble for answering a question in class, not realizing that the teacher was asking a rhetorical question, something that does not exist in his culture. The student explained, “in my culture when an adult asks you a question, you are supposed to answer.” Osa et al. (2006) highlight the care we must take in using or interpreting body language and facial expressions; they provide the example of raised eyebrows, which can indicate surprise, interest, approval, skepticism, or disapproval, depending on the culture of the speaker. Whether or not to make eye contact as a sign of respect and the appropriate finger with which to point also differ by culture.

These are only a few examples of cultural differences. Cultural differences also influence written and conversational communication styles, preferences for individual or cooperative problem solving and study, tolerance for uncertainty, conventions of politeness, and expectations for how children will interact with adults (Brook et al., 2015; Cifuentes & Ozel, 2006; Gay, 2002; Weinstein et al., 2003). Activity 5.3 asks you to think about cultural differences you have experienced.

Activity 5.3: Reflecting on Cultural Differences

Think of a specific instance of a cultural difference or misunderstanding that you have observed.

• What behaviors were central to the situation?
• What values, beliefs, or assumptions are reflected in the behaviors of each person involved?
• How might these values, beliefs, or assumptions influence a person’s experience in the classroom?
• How might your recognition of these values, beliefs, and assumptions impact your understanding of your students and your instruction?

In order to provide culturally competent instruction, librarians must develop their cultural knowledge and translate that knowledge into strategies for action. Villagran (2018) suggests librarians use the Cultural Intelligence (CQ) model as a framework for reflection and professional development. This model, shown in Figure 5.1, has four components: drive, knowledge, strategy, and action (Cultural Intelligence Center, n.d.).

• Drive: This component reflects our interest, persistence, and confidence in learning about other cultures and working in culturally diverse environments. For example, librarians might be motivated to learn about other cultures in order to improve their ability to design and deliver inclusive services for members of their community.
• Knowledge: This component is our understanding of cultural similarities and differences. Instruction librarians who want to improve their cross-cultural knowledge might seek out readings and professional development opportunities on how culture impacts teaching and learning.
• Strategy: This component reflects the metacognitive element of cultural competence; it is our ability to plan for and reflect on multicultural encounters. Culturally competent instruction librarians recognize their learners will come from varied backgrounds, develop strategies to create inclusive instruction, and reflect on their teaching experiences in order to identify areas for improvement.
• Action: This component is our ability to use appropriate behaviors during multicultural interactions. Instruction librarians can translate cultural competence into action through their instructional design and delivery and through their interactions with individual learners.

Figure 5.1: The Cultural Intelligence Model

An example may demonstrate how librarians can use the Cultural Intelligence model as a guide to professional development. Early in her career as an academic librarian, one of the authors, Melissa, heard that international students from Asia would answer questions such as “Do you understand?” with “yes” out of politeness, whether or not they understood the material being taught. Concerned that she might not be teaching international students effectively (drive), Melissa sought out articles about library services for international students and talked with a colleague with expertise in the area (knowledge). This research helped her better understand cultural differences in teaching and learning, and confirmed the need to modify the instructional strategies she used in the classroom and at the reference desk (strategy). As a result, Melissa became conscientious about speaking slowly, avoiding slang and library jargon, using open-ended questions that could not be answered with “yes,” providing written handouts, and using a pencil or her entire hand to point, instead of the index finger (action).

Librarians can use a number of strategies to develop their cultural knowledge, including reading books and articles, participating in relevant conferences and webinars, and attending cultural events such as festivals, museum exhibits, and film screenings. Reflection is an important part of cultural competence; a teaching journal, discussed in more detail in Chapter 14, can prompt librarians to reflect on classroom experiences, record teaching success, and identify areas for improvement. Conversations with colleagues are also a way to increase cultural knowledge, reflect on one’s teaching, and develop new strategies for inclusive pedagogy. Activity 5.4 is an exercise to reflect on your own learning and instructional practices using the Cultural Intelligence model.

Activity 5.4: Building Cultural Competency

Using the Cultural Intelligence Model shown in Figure 5.1, reflect on your cultural competence, either in general or with regard to a specific patron group with whom you anticipate working.

• How would you rate your cultural competence? Are you stronger in some areas, such as Drive or Knowledge, than others?
• What motivates you to improve your cultural competency?
• How have you built your cultural knowledge? What resources can you use to continue building your knowledge?
• Do you feel confident applying your cultural competence in the classroom? What strategies would you use as you plan and deliver instruction?

While learning about different cultures can empower librarians to provide more culturally relevant instruction, librarians should avoid categorizing or stereotyping specific learners. Cultural groups are not static or homogeneous, meaning learners from the same broad cultural group will not necessarily share all of the same values, beliefs, and understandings, or react in exactly the same way to instructional experiences. In addition, learners are comprised of multiple identities, of which culture is only one aspect. Thus, we should use the knowledge we develop about different cultures as a way to be alert to potential differences that could lead to misunderstandings, but not to pigeonhole or predict the behavior and experience of an individual learner.

Strategies for Inclusive Teaching

Increasing our knowledge and understanding of other cultures is only a first step toward cultural competence and inclusive teaching. We also need to parlay that understanding into instructional practices that acknowledge, appreciate, and attend to the rich diversity of our classrooms. This section presents strategies for inclusive teaching, including fostering a positive classroom climate, integrating diverse content, and using inclusive pedagogies.

Fostering a Positive Classroom Climate

Our sense of belonging in the classroom influences our motivation to learn. The Center for Teaching and Learning (2019) at Columbia University identifies four types of classroom environments:

• Explicitly Marginalizing: The instructor or other students say or do things, such as committing microaggressions or repeating stereotypes, that exclude learners and perspectives from marginalized backgrounds.
• Implicitly Marginalizing: The instructor excludes some learners through subtle actions such as calling primarily on male students or using examples solely from the predominant culture.
• Implicitly Centralizing: The instructor will discuss issues of marginalization and diversity if a student raises the topic, but such conversations are not planned or presented as essential.
• Explicitly Centralizing: The instructor intentionally integrates marginalized perspectives into course content, raises issues of diversity and inclusion, and takes action to foster sensitivity, such as establishing norms for discussion and group work.

While the environment in any classroom can fluctuate, the overall classroom climate is often less inclusive and welcoming than instructors realize. In one study, instructors rated their course as falling midway between implicitly and explicitly centralizing, while learners rated the same course as implicitly marginalizing (Center for Teaching and Learning, 2019).

One conclusion we might take away from this research is the need for critical self-reflection on the part of instructors. In addition, the research suggests that instructors must make a concerted effort to create an inclusive classroom environment. Some strategies we can use include:

• Express interest in students. Welcoming participants as they enter the room and learning their names help participants feel recognized (if you are worried about remembering names, you can have them create a table tent or name tag). In addition, instructors should come out from behind podiums, which can be perceived as distancing, to engage with participants. Reflective activities such as minute papers also offer opportunities to respond to individuals and demonstrate interest in their learning (Center for Teaching and Learning, n.d.; Bunner, 2017).
• Establish ground rules for discussions. Establishing guidelines for civil, constructive interaction is becoming more common in credit courses; oftentimes, instructors engage students in creating these guidelines in order to foster a sense of ownership. The time constraints of library workshops may not allow for lengthy or collaborative agreements; however, librarians can establish simple ground rules, such as respecting the opinions of others and valuing diverse perspectives, at the beginning of sessions (Watts, 2017).
• Foster student-to-student relationships. Instructional strategies that foster interaction such as think-pair-share, small group work, and class discussions promote positive classroom relationships.
• Make expectations explicit. As mentioned earlier, cultural background can influence classroom behaviors such as participation styles and how, or whether, to ask questions. Instructors should make their expectations explicit with comments such as “I hope you will ask a lot of questions as we go along,” or “Right now we are going to work independently, but later we’ll share our work with others.”
• Express high expectations for all students. Instructors should use an encouraging, positive tone, while also setting high expectations for all learners. Gay (2002) and Weinstein et al. (2003) point out that stereotypes based on race and/or gender can cause instructors to lower expectations for certain groups of students. Weinstein et al. (2003) offer the example of a non-native speaker of English who was offended when a teacher told him his English was “good,” rather than suggesting he continue to practice. He felt the former was patronizing and did not help him improve his language skills.
• Address microaggressions and other forms of bias. As discussed earlier, instructors should be mindful of stereotypes and take care not to perpetuate them, and to practice intervention strategies that can be used when microaggressions occur in the classroom.
• Ask for feedback. Instructors can use course evaluations and classroom observations to gather feedback on how well they foster an inclusive classroom environment.

Integrating Diverse Content

All learners have a right to instructional offerings that address their needs and interests. At the program level, we should offer workshops and other instructional resources on a wide variety of topics that are suitable for patrons of varied ages and ability levels. We should take care to schedule classes and programs at varied times to ensure access for the widest number of people. For example, a traditional storytime program on a weekday morning will serve families with a stay-at-home parent as well as families where parents work the late shift or on weekends, while a pajama storytime held in the evening will serve families where parents and other caregivers work during the day.

In addition, our course content should reflect the diversity of our communities and the larger world. Not only does this allow learners to “see” themselves in the curriculum, it provides opportunities for all learners to learn about diversity and equity and to develop cultural competence. In addition, integrating discussions of diversity and equity throughout the curriculum ensures these issues are not “othered” or treated as an addendum to a curriculum where whiteness and heterosexuality are the norm. Further, we must engage these topics in authentic ways, rather than with benign or superficial celebrations of multiculturalism (Bunner, 2017, p. 42; Kumasi & Hill, 2011, p. 252). Some strategies librarians can use to integrate diversity and inclusion into instructional content:

• Use diverse examples. For instance, a librarian teaching a workshop on Overdrive can conduct sample searches featuring authors of diverse identities. An academic librarian or archivist teaching students to locate primary documents from World War II might highlight sites with materials from the Tuskegee Airmen or the all Japanese-American 442nd Regiment. Hinchliffe (2016) notes that librarians can call attention to issues of human rights through the examples used in class.
• Choose metaphors and analogies carefully. While metaphors and analogies can help learners build on prior knowledge and make concepts more concrete, they are often embedded in cultural knowledge or experiences that not everyone will share. Similarly, pop culture references may exclude learners based on their age or cultural background, although in some cases librarians can pause to offer a brief explanation.
• Discuss how issues of race, class, and gender impact the material being covered. Gorski and Swalwell (2015, p. 36) argue, “at the heart of a curriculum that is meaningfully multicultural lie principles of equity and social justice—purposeful attention to issues like racism, homophobia, sexism, and economic inequality.” Gay (2002) suggests that instructors address topics such as racism, historical atrocities, and structures of power, and contextualize issues within race, class, and gender. While librarians may initially feel uncomfortable discussing challenging topics in the classroom, Bunner (2017, p. 43) found that ignoring issues of race is more problematic for students of color than imperfect conversations.
• Model how participants can seek out marginalized voices and perspectives. In addition to incorporating a wide range of perspectives into our own teaching, we can encourage others to adopt a wider perspective and demonstrate resources and search strategies to uncover marginalized voices.

As part of creating a more inclusive curriculum, librarians will need to build collections that incorporate the histories and voices of marginalized groups. After all, it will be difficult to use diverse examples or demonstrate strategies for surfacing marginalized voices if our print and online collections do not contain that material. In addition, we need to be skilled at working within these collections. Curry (2005, p. 70) found that small behaviors like raised eyebrows, biting one’s lip, or a reserved or even neutral affect communicated discomfort while helping a patron research LGBTQIA+ topics, leading the patron to be less likely to ask for help in the future. In the same study, Curry (2005, p. 71) found that even librarians who indicated a willingness to help the patron lacked the necessary knowledge to identify appropriate sources of information. While Curry’s study focused on assisting patrons at the reference desk, her findings are very applicable to the classroom.

Part and parcel with building our knowledge of resources, we must understand the biases and weaknesses built into existing search systems, and develop strategies to find information within (or despite) those systems. Drabinski (2008) shares her experience of teaching with a colleague who incorrectly assumed that if LCSH has a heading for “African American women,” it must also have a heading for “white women” and advised students to use that phrase when searching. Noble (2012, 2018) shows that search engines such as Google are not neutral; rather, they replicate the biases inherent in society, delivering search results that reinforce stereotypical depictions of women and people of color. Ultimately, librarians who are committed to integrating equity and inclusion into the classroom must step back to look at the totality of their library’s spaces, collections, and systems.

Inclusive Pedagogy

Pedagogy is our approach to teaching. It reflects our understanding of the learning process, our goals for the classroom environment and student learning, and, subsequently, the activities one plans for the classroom. Instructors who practice inclusive pedagogy recognize that students have varied preferences for and comfort levels with different learning activities such as lecture, whole-class discussion, and small group work, and offer varied ways for learners to engage in the classroom.

Instructors can select from a wide variety of activities when planning instructional sessions. In fact, novice instructors are sometimes overwhelmed by the seemingly endless array of options. Chávez and Longerbeam (2016, pp. 8-9) suggest cultural approaches to teaching and learning range from “individuated,” which tend to compartmentalize content and treat learning as an individual experience, to “integrated,” which are more interconnected and focus on shared learning experiences. Instructors might seek to balance activities that reflect an individuated approach such as lecture, independent practice, and reflective writing, with activities that reflect an integrated approach such as discussion, case studies, and collaborative work.

Another approach we can take is balancing instructor-centered and learner-centered activities. Instructor-centered activities are those in which the instructor has a strong role in directing course content and the process of student learning, such as lecture and demonstration. In student-centered activities, students direct and shape their own learning; examples of student-centered activities include small group work, case-based and problem-based learning, and practice exercises that allow students to explore their own interests.

In addition to varying classroom activities, instructors can offer learners choices. For example, during an online searching activity, we might give learners the option of trying a task on their own or collaborating with their neighbor. Instructors can also adapt activities to create a more inclusive environment. For example, workshop participants might be reluctant to engage in a discussion with others they do not know well, especially if the topic is sensitive. A think-pair-share, which offers time for individual reflection and ordering one’s thoughts, or a small group discussion, where one shares ideas with just a few others, may feel safer for participants and can be used as a lead-in to a whole-class discussion or activity.

Emancipatory Education

While inclusive pedagogy outlines the strategies we can take as instructors to honor our learners’ experiences and make our classrooms and instruction welcoming and accessible to all learners, critical pedagogy also recognizes learners as agents in the classroom and in the world. In Pedagogy of the Oppressed , Freire (2000) discusses the emancipatory aspects of education, or how education can be structured so as to empower marginalized and oppressed communities to liberate themselves from systems of oppression. Crucial to Freire’s approach is that the learners are the agents of their own liberation. Instructors can facilitate this process by recognizing and mitigating bias and through the inclusive strategies outlined in this chapter, but ultimately, learners should be empowered to act on their own behalf.

We can foster emancipatory education within the library classroom by surfacing oppressive practices not only within education but within library systems and structures, facilitating dialogues about these practices, and encouraging students to imagine and adopt roles for themselves in challenging those systems. Chapter 2 outlines steps we could take in the context of critical information literacy, such as helping students recognize how prevailing publishing practices and notions of authority favor some voices and marginalize others, and encouraging them to seek out those voices that have been marginalized to include their perspectives. We can also work with learners to take action in the wider world, as librarians at Dartmouth College did when they collaborated with students to petition the Library of Congress to eliminate the term “illegal aliens” from its official subject headings (Albright, 2019).

Our learners bring varied backgrounds, identities, and educational needs to the classroom. Using critical pedagogy as a guide, librarians can adopt inclusive teaching practices that create classrooms, libraries, and, ultimately, communities that are more just and equitable for all members.

Key takeaways from this chapter include:

• Instructors should understand the role unconscious bias plays in discrimination and inequity, and develop strategies to prevent and address microaggressions, othering, and deficit thinking.
• Cultural competence is a set of knowledge, skills, and dispositions that enable librarians to interact effectively with patrons from diverse backgrounds. Instruction librarians need to understand how culture affects teaching and learning, and develop strategies for inclusive pedagogy.
• Elements of inclusive teaching include fostering a positive classroom climate, integrating diverse perspectives and issues of diversity and equity into course content, and using inclusive pedagogies.

An Evaluative Review of Barriers to Critical Thinking in Educational and Real-World Settings

Associated data.

No new data were created or analyzed in this study. Data sharing is not applicable to this article.

Though a wide array of definitions and conceptualisations of critical thinking have been offered in the past, further elaboration on some concepts is required, particularly with respect to various factors that may impede an individual’s application of critical thinking, such as in the case of reflective judgment. These barriers include varying levels of epistemological engagement or understanding, issues pertaining to heuristic-based thinking and intuitive judgment, as well as emotional and biased thinking. The aim of this review is to discuss such barriers and evaluate their impact on critical thinking in light of perspectives from research in an effort to reinforce the ‘completeness’ of extant critical thinking frameworks and to enhance the potential benefits of implementation in real-world settings. Recommendations and implications for overcoming such barriers are also discussed and evaluated.

1. Introduction

Critical thinking (CT) is a metacognitive process—consisting of a number of skills and dispositions—that, through purposeful, self-regulatory reflective judgment, increases the chances of producing a logical solution to a problem or a valid conclusion to an argument ( Dwyer 2017 , 2020 ; Dwyer et al. 2012 , 2014 , 2015 , 2016 ; Dwyer and Walsh 2019 ; Quinn et al. 2020 ).

CT has long been identified as a desired outcome of education ( Bezanilla et al. 2019 ; Butler et al. 2012 ; Dwyer 2017 ; Ennis 2018 ), given that it facilitates a more complex understanding of information ( Dwyer et al. 2012 ; Halpern 2014 ), better judgment and decision-making ( Gambrill 2006 ) and less dependence on cognitive bias and heuristic thinking ( Facione and Facione 2001 ; McGuinness 2013 ). A vast body of research (e.g., Dwyer et al. 2012 ; Gadzella 1996 ; Hitchcock 2004 ; Reed and Kromrey 2001 ; Rimiene 2002 ; Solon 2007 ), including various meta-analyses (e.g., Abrami et al. 2008 , 2015 ; Niu et al. 2013 ; Ortiz 2007 ), indicates that CT can be enhanced through targeted, explicit instruction. Though CT can be taught in domain-specific areas, its domain-generality means that it can be taught across disciplines and in relation to real-world scenarios ( Dwyer 2011 , 2017 ; Dwyer and Eigenauer 2017 ; Dwyer et al. 2015 ; Gabennesch 2006 ; Halpern 2014 ). Indeed, the positive outcomes associated with CT transcend educational settings into real-world, everyday situations, which is important because CT is necessary for a variety of social and interpersonal contexts where good decision-making and problem-solving are needed on a daily basis ( Ku 2009 ). However, regardless of domain-specificity or domain-generality of instruction, the transferability of CT application has been an issue in CT research (e.g., see Dumitru 2012 ). This is an important consideration because issues with transferability—for example, in real-world settings—may imply something lacking in CT instruction.

In light of the large, aforementioned body of research focusing on enhancing CT through instruction, a growing body of research has also evaluated the manner in which CT instruction is delivered (e.g., Abrami et al. 2008 , 2015 ; Ahern et al. 2019 ; Cáceres et al. 2020 ; Byerly 2019 ; Dwyer and Eigenauer 2017 ), along with additional considerations for and the barriers to such education, faced by teachers and students alike (e.g., Aliakbari and Sadeghdaghighi 2013 ; Cáceres et al. 2020 ; Cornell et al. 2011 ; Lloyd and Bahr 2010 ; Ma and Liu 2022 ; Ma and Luo 2021 ; Rear 2019 ; Saleh 2019 ); for example, those regarding conceptualisation, beliefs about CT, having feasible time for CT application and CT’s aforementioned transferability. However, there is a significant lack of research investigating barriers to CT application by individuals in real-world settings, even by those who have enjoyed benefits from previous CT instruction. Thus, perhaps the previously conjectured ‘something lacking in CT instruction’ refers to, in conjunction with the teaching of what CT consists of, making clear to students what barriers to CT application we face.

Simply, CT instruction is designed in such a way as to enhance the likelihood of positive decision-making outcomes. However, there are a variety of barriers that can impede an individual’s application of CT, regardless of past instruction with respect to ‘how to conduct CT’. For example, an individual might be regarded as a ‘critical thinker’ because they apply it in a vast majority of appropriate scenarios, but that does not ensure that they apply CT in all such appropriate scenarios. What keeps them from applying CT in those scenarios might well be one of a number of barriers to CT that often go unaddressed in CT instruction, particularly if such instruction is exclusively focused on skills and dispositions. Perhaps too much focus is placed on what educators are teaching their students to do in their CT courses as opposed to what educators should be recommending their students to look out for or advising what they should not be doing. That is, perhaps just as important for understanding what CT is and how it is conducted (i.e., knowing what to do) is a genuine awareness of the various factors and processes that can impede CT; and so, for an individual to think critically, they must know what to look out for and be able to monitor for such barriers to CT application.

To clarify, thought has not changed regarding what CT is or the cognitive/metacognitive processes at its foundation (e.g., see Dwyer 2017 ; Dwyer et al. 2014 ; Ennis 1987 , 1996 , 1998 ; Facione 1990 ; Halpern 2014 ; Paul 1993 ; Paul and Elder 2008 ); rather, additional consideration of issues that have potential to negatively impact CT is required, such as those pertaining to epistemological engagement; intuitive judgment; as well as emotional and biased thinking. This notion has been made clear through what might be perceived of as a ‘loud shout’ for CT over at least the past 10–15 years in light of growing political, economic, social, and health-related concerns (e.g., ‘fake news’, gaps between political views in the general population, various social movements and the COVID-19 pandemic). Indeed, there is a dearth of research on barriers to CT ( Haynes et al. 2016 ; Lloyd and Bahr 2010 ; Mangena and Chabeli 2005 ; Rowe et al. 2015 ). As a result, this evaluative perspective review aims to provide an impetus for updating the manner in which CT education is approached and, perhaps most importantly, applied in real-world settings—through further identifying and elaborating on specific barriers of concern in order to reinforce the ‘completeness’ of extant CT frameworks and to enhance the potential benefits of their implementation 1 .

2. Barriers to Critical Thinking

2.1. inadequate skills and dispositions.

In order to better understand the various barriers to CT that will be discussed, the manner in which CT is conceptualised must first be revisited. Though debate over its definition and what components are necessary to think critically has existed over the 80-plus years since the term’s coining (i.e., Glaser 1941 ), it is generally accepted that CT consists of two main components: skills and dispositions ( Dwyer 2017 ; Dwyer et al. 2012 , 2014 ; Ennis 1996 , 1998 ; Facione 1990 ; Facione et al. 2002 ; Halpern 2014 ; Ku and Ho 2010a ; Perkins and Ritchhart 2004 ; Quinn et al. 2020 ). CT skills—analysis, evaluation, and inference—refer to the higher-order, cognitive, ‘task-based’ processes necessary to conduct CT (e.g., see Dwyer et al. 2014 ; Facione 1990 ). CT dispositions have been described as inclinations, tendencies, or willingness to perform a given thinking skill (e.g., see Dwyer et al. 2016 ; Siegel 1999 ; Valenzuela et al. 2011 ), which may relate to attitudinal and intellectual habits of thinking, as well as motivational processes ( Ennis 1996 ; Norris 1994 ; Paul and Elder 2008 ; Perkins et al. 1993 ; Valenzuela et al. 2011 ). The relationship between CT skills and dispositions has been argued to be mutually dependent. As a result, overemphasising or encouraging the development of one over the other is a barrier to CT as a whole. Though this may seem obvious, it remains the case that CT instruction often places added emphasis on skills simply because they can be taught (though that does not ensure that everyone has or will be taught such skills), whereas dispositions are ‘trickier’ (e.g., see Dwyer 2017 ; Ku and Ho 2010a ). That is, it is unlikely that simply ‘teaching’ students to be motivated towards CT or to value it over short-instructional periods will actually meaningfully enhance it. Moreover, debate exists over how best to train disposition or even measure it. With that, some individuals might be more ‘inherently’ disposed to CT in light of their truth-seeking, open-minded, or inquisitive natures ( Facione and Facione 1992 ; Quinn et al. 2020 ). The barrier, in this context, is how we can enhance the disposition of those who are not ‘inherently’ inclined. For example, though an individual may possess the requisite skills to conduct CT, it does not ensure the tendency or willingness to apply them; and conversely, having the disposition to apply CT does not mean that one has the ability to do so ( Valenzuela et al. 2011 ). Given the pertinence of CT skills and dispositions to the application of CT in a broader sense, inadequacies in either create a barrier to application.

2.2. Epistemological (Mis)Understanding

To reiterate, most extant conceptualisations of CT focus on the tandem working of skills and dispositions, though significantly fewer emphasise the reflective judgment aspect of CT that might govern various associated processes ( Dawson 2008 ; Dwyer 2017 ; Dwyer et al. 2014 , 2015 ; King and Kitchener 1994 , 2004 ; Stanovich and Stanovich 2010 ). Reflective judgment (RJ) refers to a self-regulatory process of decision-making, with respect to taking time to engage one’s understanding of the nature, limits, and certainty of knowing and how this can affect the defense of their reasoning ( Dwyer 2017 ; King and Kitchener 1994 ; Ku and Ho 2010b ). The ability to metacognitively ‘think about thinking’ ( Flavell 1976 ; Ku and Ho 2010b ) in the application of critical thinking skills implies a reflective sensibility consistent with epistemological understanding and the capacity for reflective judgement ( Dwyer et al. 2015 ; King and Kitchener 1994 ). Acknowledging levels of (un)certainty is important in CT because the information a person is presented with (along with that person’s pre-existing knowledge) often provides only a limited source of information from which to draw a conclusion. Thus, RJ is considered a component of CT ( Baril et al. 1998 ; Dwyer et al. 2015 ; Huffman et al. 1991 ) because it allows one to acknowledge that epistemological understanding is necessary for recognising and judging a situation in which CT may be required ( King and Kitchener 1994 ). For example, the interdependence between RJ and CT can be seen in the way that RJ influences the manner in which CT skills like analysis and evaluation are conducted or the balance and perspective within the subsequent inferences drawn ( Dwyer et al. 2015 ; King et al. 1990 ). Moreover, research suggests that RJ development is not a simple function of age or time but more so a function of the amount of active engagement an individual has working in problem spaces that require CT ( Brabeck 1981 ; Dawson 2008 ; Dwyer et al. 2015 ). The more developed one’s RJ, the better able one is to present “a more complex and effective form of justification, providing more inclusive and better integrated assumptions for evaluating and defending a point of view” ( King and Kitchener 1994, p. 13 ).

Despite a lesser focus on RJ, research indicates a positive relationship between it and CT ( Baril et al. 1998 ; Brabeck 1981 ; Dawson 2008 ; Dwyer et al. 2015 ; Huffman et al. 1991 ; King et al. 1990 )—the understanding of which is pertinent to better understanding the foundation to CT barriers. For example, when considering one’s proficiency in CT skills, there might come a time when the individual becomes so good at using them that their application becomes something akin to ‘second nature’ or even ‘automatic’. However, this creates a contradiction: automatic thinking is largely the antithesis of reflective judgment (even though judgment is never fully intuitive or reflective; see Cader et al. 2005 ; Dunwoody et al. 2000 ; Hamm 1988 ; Hammond 1981 , 1996 , 2000 )—those who think critically take their time and reflect on their decision-making; even if the solution/conclusion drawn from the automatic thinking is ‘correct’ or yields a positive outcome, it is not a critically thought out answer, per se. Thus, no matter how skilled one is at applying CT skills, once the application becomes primarily ‘automatic’, the thinking ceases to be critical ( Dwyer 2017 )—a perspective consistent with Dual Process Theory (e.g., Stanovich and West 2000 ). Indeed, RJ acts as System 2 thinking ( Stanovich and West 2000 ): it is slow, careful, conscious, and consistent ( Kahneman 2011 ; Hamm 1988 ); it is associated with high cognitive control, attention, awareness, concentration, and complex computation ( Cader et al. 2005 ; Kahneman 2011 ; Hamm 1988 ); and accounts for epistemological concerns—consistent not only with King and Kitchener’s ( 1994 ) conceptualisation but also Kuhn’s ( 1999 , 2000 ) perspective on metacognition and epistemological knowing . This is where RJ comes into play as an important component of CT—interdependent among the requisite skills and dispositions ( Baril et al. 1998 ; Dwyer et al. 2015 )—it allows one to acknowledge that epistemological understanding is vital to recognising and judging a situation in which CT is required ( King and Kitchener 1994 ). With respect to the importance of epistemological understanding, consider the following examples for elaboration.

The primary goal of CT is to enhance the likelihood of generating reasonable conclusions and/or solutions. Truth-seeking is a CT disposition fundamental to the attainment of this goal ( Dwyer et al. 2016 ; Facione 1990 ; Facione and Facione 1992 ) because if we just applied any old nonsense as justification for our arguments or solutions, they would fail in the application and yield undesirable consequences. Despite what may seem like truth-seeking’s obvious importance in this context, all thinkers succumb to unwarranted assumptions on occasion (i.e., beliefs presumed to be true without adequate justification). It may also seem obvious, in context, that it is important to be able to distinguish facts from beliefs. However, the concepts of ‘fact’ or ‘truth’, with respect to how much empirical support they have to validate them, also require consideration. For example, some might conceptualise truth as factual information or information that has been or can be ‘proven’ true. Likewise, ‘proof’ is often described as evidence establishing a fact or the truth of a statement—indicating a level of absolutism. However, the reality is that we cannot ‘prove’ things—as scientists and researchers well know—we can only disprove them, such as in experimental settings where we observe a significant difference between groups on some measure—we do not prove the hypothesis correct, rather, we disprove the null hypothesis. This is why, in large part, researchers and scientists use cautious language in reporting their results. We know the best our findings can do is reinforce a theory—another concept often misconstrued in the wider population as something like a hypothesis, as opposed to what it actually entails: a robust model for how and/or why a given phenomenon might occur (e.g., gravity). Thus, theories will hold ‘true’ until they are falsified—that is, disproven (e.g., Popper [1934] 1959 , 1999 ).

Unfortunately, ‘proof’, ‘prove’, and ‘proven’—words that ensure certainty to large populations—actually disservice the public in subtle ways that can hinder CT. For example, a company that produces toothpaste might claim its product to be ‘clinically proven’ to whiten teeth. Consumers purchasing that toothpaste are likely to expect to have whiter teeth after use. However, what happens—as often may be the case—if it does not whiten their teeth? The word ‘proven’ implies a false claim in context. Of course, those in research understand that the word’s use is a marketing ploy, given that ‘clinically proven’ sounds more reassuring to consumers than ‘there is evidence to suggest…’; but, by incorrectly using words like ‘proven’ in our daily language, we reinforce a misunderstanding of what it means to assess, measure and evaluate—particularly from a scientific standpoint (e.g., again, see Popper [1934] 1959 , 1999 ).

Though this example may seem like a semantic issue, it has great implications for CT in the population. For example, a vast majority of us grew up being taught the ‘factual’ information that there were nine planets in our solar system; then, in 2006, Pluto was reclassified as a dwarf planet—no longer being considered a ‘major’ planet of our solar system. As a result, we now have eight planets. This change might be perceived in two distinct ways: (1) ‘science is amazing because it’s always developing—we’ve now reached a stage where we know so much about the solar system that we can differentiate celestial bodies to the extent of distinguishing planets from dwarf planets’; and (2) ‘I don’t understand why these scientists even have jobs, they can’t even count planets’. The first perspective is consistent with that of an individual with epistemological understanding and engagement that previous understandings of models and theories can change, not necessarily because they were wrong, but rather because they have been advanced in light of gaining further credible evidence. The second perspective is consistent with that of someone who has failed to engage epistemological understanding, who does not necessarily see that the change might reflect progress, who might be resistant to change, and who might grow in distrust of science and research in light of these changes. The latter point is of great concern in the CT research community because the unwarranted cynicism and distrust of science and research, in context, may simply reflect a lack of epistemological understanding or engagement (e.g., to some extent consistent with the manner in which conspiracy theories are developed, rationalised and maintained (e.g., Swami and Furnham 2014 )). Notably, this should also be of great concern to education departments around the world, as well as society, more broadly speaking.

Upon considering epistemological engagement in more practical, day-to-day scenarios (or perhaps a lack thereof), we begin to see the need for CT in everyday 21st-century life—heightened by the ‘new knowledge economy’, which has resulted in exponential increases in the amount of information made available since the late 1990s (e.g., Darling-Hammond 2008 ; Dwyer 2017 ; Jukes and McCain 2002 ; Varian and Lyman 2003 ). Though increased amounts of and enhanced access to information are largely good things, what is alarming about this is how much of it is misinformation or disinformation ( Commission on Fake News and the Teaching of Critical Literacy in Schools 2018 ). Truth be told, the new knowledge economy is anything but ‘new’ anymore. Perhaps, over the past 10–15 years, there has been an increase in the need for CT above and beyond that seen in the ‘economy’s’ wake—or maybe ever before; for example, in light of the social media boom, political unrest, ‘fake news’, and issues regarding health literacy. The ‘new’ knowledge economy has made it so that knowledge acquisition, on its own, is no longer sufficient for learning—individuals must be able to work with and adapt information through CT in order to apply it appropriately ( Dwyer 2017 ).

Though extant research has addressed the importance of epistemological understanding for CT (e.g., Dwyer et al. 2014 ), it does not address how not engaging it can substantially hinder it—regardless of how skilled or disposed to think critically an individual may be. Notably, this is distinct from ‘inadequacies’ in, say, memory, comprehension, or other ‘lower-order’ cognitively-associated skills required for CT ( Dwyer et al. 2014 ; Halpern 2014 ; see, again, Note 1) in that reflective judgment is essentially a pole on a cognitive continuum (e.g., see Cader et al. 2005 ; Hamm 1988 ; Hammond 1981 , 1996 , 2000 ). Cognitive Continuum Theory postulates a continuum of cognitive processes anchored by reflective judgment and intuitive judgment, which represents how judgment situations or tasks relate to cognition, given that thinking is never purely reflective, nor is it completely intuitive; rather, it rests somewhere in between ( Cader et al. 2005 ; Dunwoody et al. 2000 ). It is also worth noting that, in Cognitive Continuum Theory, neither reflective nor intuitive judgment is assumed, a priori, to be superior ( Dunwoody et al. 2000 ), despite most contemporary research on judgment and decision-making focusing on the strengths of RJ and limitations associated with intuitive judgment ( Cabantous et al. 2010 ; Dhami and Thomson 2012 ; Gilovich et al. 2002 ). Though this point regarding superiority is acknowledged and respected (particularly in non-CT cases where it is advantageous to utilise intuitive judgment), in the context of CT, it is rejected in light of the example above regarding the automaticity of thinking skills.

2.3. Intuitive Judgment

The manner in which human beings think and the evolution of which, over millions of years, is a truly amazing thing. Such evolution has made it so that we can observe a particular event and make complex computations regarding predictions, interpretations, and reactions in less than a second (e.g., Teichert et al. 2014 ). Unfortunately, we have become so good at it that we often over-rely on ‘fast’ thinking and intuitive judgments that we have become ‘cognitively lazy’, given the speed at which we can make decisions with little energy ( Kahneman 2011 ; Simon 1957 ). In the context of CT, this ‘lazy’ thinking is an impediment (as in opposition to reflective judgment). For example, consider a time in which you have been presented numeric data on a topic, and you instantly aligned your perspective with what the ‘numbers indicate’. Of course, numbers do not lie… but people do—that is not to say that the person who initially interpreted and then presented you with those numbers is trying to disinform you; rather, the numbers presented might not tell the full story (i.e., the data are incomplete or inadequate, unbeknownst to the person reporting on them); and thus, there might be alternative interpretations to the data in question. With that, there most certainly are individuals who will wish to persuade you to align with their perspective, which only strengthens the impetus for being aware of intuitive judgment as a barrier. Consider another example: have you ever accidentally insulted someone at work, school, or in a social setting? Was it because the statement you made was based on some kind of assumption or stereotype? It may have been an honest mistake, but if a statement is made based on what one thinks they know, as opposed to what they actually know about the situation—without taking the time to recognise that all situations are unique and that reflection is likely warranted in light of such uncertainty—then it is likely that the schema-based ‘intuitive judgment’ is what is a fault here.

Our ability to construct schemas (i.e., mental frameworks for how we interpret the world) is evolutionarily adaptive in that these scripts allow us to: make quick decisions when necessary and without much effort, such as in moments of impending danger, answer questions in conversation; interpret social situations; or try to stave off cognitive load or decision fatigue ( Baumeister 2003 ; Sweller 2010 ; Vohs et al. 2014 ). To reiterate, research in the field of higher-order thinking often focuses on the failings of intuitive judgment ( Dwyer 2017 ; Hamm 1988 ) as being limited, misapplied, and, sometimes, yielding grossly incorrect responses—thus, leading to faulty reasoning and judgment as a result of systematic biases and errors ( Gilovich et al. 2002 ; Kahneman 2011 ; Kahneman et al. 1982 ; Slovic et al. 1977 ; Tversky and Kahneman 1974 ; in terms of schematic thinking ( Leventhal 1984 ), system 1 thinking ( Stanovich and West 2000 ; Kahneman 2011 ), miserly thinking ( Stanovich 2018 ) or even heuristics ( Kahneman and Frederick 2002 ; Tversky and Kahneman 1974 ). Nevertheless, it remains that such protocols are learned—not just through experience (as discussed below), but often through more ‘academic’ means. For example, consider again the anecdote above about learning to apply CT skills so well that it becomes like ‘second nature’. Such skills become a part of an individual’s ‘mindware’ ( Clark 2001 ; Stanovich 2018 ; Stanovich et al. 2016 ) and, in essence, become heuristics themselves. Though their application requires RJ for them to be CT, it does not mean that the responses yielded will be incorrect.

Moreover, despite the descriptions above, it would be incorrect, and a disservice to readers to imply that RJ is always right and intuitive judgment is always wrong, especially without consideration of the contextual issues—both intuitive and reflective judgments have the potential to be ‘correct’ or ‘incorrect’ with respect to validity, reasonableness or appropriateness. However, it must also be acknowledged that there is a cognitive ‘miserliness’ to depending on intuitive judgment, in which case, the ability to detect and override this dependence ( Stanovich 2018 )—consistent with RJ, is of utmost importance if we care about our decision-making. That is, if we care about our CT (see below for a more detailed discussion), we must ignore the implicit ‘noise’ associated with the intuitive judgment (regardless of whether or not it is ‘correct’) and, instead, apply the necessary RJ to ensure, as best we can, that the conclusion or solution is valid, reasonable or appropriate.

Although, such a recommendation is much easier said than done. One problem with relying on mental shortcuts afforded by intuition and heuristics is that they are largely experience-based protocols. Though that may sound like a positive thing, using ‘experience’ to draw a conclusion in a task that requires CT is erroneous because it essentially acts as ‘research’ based on a sample size of one; and so, ‘findings’ (i.e., one’s conclusion) cannot be generalised to the larger population—in this case, other contexts or problem-spaces ( Dwyer 2017 ). Despite this, we often over-emphasise the importance of experience in two related ways. First, people have a tendency to confuse experience for expertise (e.g., see the Dunning–KrugerEffect (i.e., the tendency for low-skilled individuals to overestimate their ability in tasks relevant to said skill and highly skilled individuals to underestimate their ability in tasks relevant to said skills); see also: ( Kruger and Dunning 1999 ; Mahmood 2016 ), wherein people may not necessarily be expert, rather they may just have a lot of experience completing a task imperfectly or wrong ( Dwyer and Walsh 2019 ; Hammond 1996 ; Kahneman 2011 ). Second, depending on the nature of the topic or problem, people often evaluate experience on par with research evidence (in terms of credibility), given its personalised nature, which is reinforced by self-serving bias(es).

When evaluating topics in domains wherein one lacks expertise, the need for intellectual integrity and humility ( Paul and Elder 2008 ) in their RJ is increased so that the individual may assess what knowledge is required to make a critically considered judgment. However, this is not necessarily a common response to a lack of relevant knowledge, given that when individuals are tasked with decision-making regarding a topic in which they do not possess relevant knowledge, these individuals will generally rely on emotional cues to inform their decision-making (e.g., Kahneman and Frederick 2002 ). Concerns here are not necessarily about the lack of domain-specific knowledge necessary to make an accurate decision, but rather the (1) belief of the individual that they have the knowledge necessary to make a critically thought-out judgment, even when this is not the case—again, akin to the Dunning–Kruger Effect ( Kruger and Dunning 1999 ); or (2) lack of willingness (i.e., disposition) to gain additional, relevant topic knowledge.

One final problem with relying on experience for important decisions, as alluded to above, is that when experience is engaged, it is not necessarily an objective recollection of the procedure. It can be accompanied by the individual’s beliefs, attitudes, and feelings—how that experience is recalled. The manner in which an individual draws on their personal experience, in light of these other factors, is inherently emotion-based and, likewise, biased (e.g., Croskerry et al. 2013 ; Loftus 2017 ; Paul 1993 ).

2.4. Bias and Emotion

Definitions of CT often reflect that it is to be applied to a topic, argument, or problem of importance that the individual cares about ( Dwyer 2017 ). The issue of ‘caring’ is important because it excludes judgment and decision-making in day-to-day scenarios that are not of great importance and do not warrant CT (e.g., ‘what colour pants best match my shirt’ and ‘what to eat for dinner’); again, for example, in an effort to conserve time and cognitive resources (e.g., Baumeister 2003 ; Sweller 2010 ). However, given that ‘importance’ is subjective, it essentially boils down to what one cares about (e.g., issues potentially impactful in one’s personal life; topics of personal importance to the individual; or even problems faced by an individual’s social group or work organisation (in which case, care might be more extrinsically-oriented). This is arguably one of the most difficult issues to resolve in CT application, given its contradictory nature—where it is generally recommended that CT should be conducted void of emotion and bias (as much as it can be possible), at the same time, it is also recommended that it should only be applied to things we care about. As a result, the manner in which care is conceptualised requires consideration. For example, in terms of CT, care can be conceptualised as ‘concern or interest; the attachment of importance to a person, place, object or concept; and serious attention or consideration applied to doing something correctly or to avoid damage or risk’; as opposed to some form of passion (e.g., intense, driving or over-powering feeling or conviction; emotions as distinguished from reason; a strong liking or desire for or devotion to some activity, object or concept). In this light, care could be argued as more of a dispositional or self-regulatory factor than emotional bias; thus, making it useful to CT. Though this distinction is important, the manner in which care is labeled does not lessen the potential for biased emotion to play a role in the thinking process. For example, it has been argued that if one cares about the decision they make or the conclusion they draw, then the individual will do their best to be objective as possible ( Dwyer 2017 ). However, it must also be acknowledged that this may not always be the case or even completely feasible (i.e., how can any decision be fully void of emotional input? )—though one may strive to be as objective as possible, such objectivity is not ensured given that implicit bias may infiltrate their decision-making (e.g., taking assumptions for granted as facts in filling gaps (unknowns) in a given problem-space). Consequently, such implicit biases may be difficult to amend, given that we may not be fully aware of them at play.

With that, explicit biases are just as concerning, despite our awareness of them. For example, the more important an opinion or belief is to an individual, the greater the resistance to changing their mind about it ( Rowe et al. 2015 ), even in light of evidence indicating the contrary ( Tavris and Aronson 2007 ). In some cases, the provision of information that corrects the flawed concept may even ‘backfire’ and reinforce the flawed or debunked stance ( Cook and Lewandowsky 2011 ). This cognitive resistance is an important barrier to CT to consider for obvious reasons—as a process; it acts in direct opposition to RJ, the skill of evaluation, as well as a number of requisite dispositions towards CT, including truth-seeking and open-mindedness (e.g., Dwyer et al. 2014 , 2016 ; Facione 1990 ); and at the same time, yields important real-world impacts (e.g., see Nyhan et al. 2014 ).

The notion of emotion impacting rational thought is by no means a novel concept. A large body of research indicates a negative impact of emotion on decision-making (e.g., Kahneman and Frederick 2002 ; Slovic et al. 2002 ; Strack et al. 1988 ), higher-order cognition ( Anticevic et al. 2011 ; Chuah et al. 2010 ; Denkova et al. 2010 ; Dolcos and McCarthy 2006 ) and cognition, more generally ( Iordan et al. 2013 ; Johnson et al. 2005 ; Most et al. 2005 ; Shackman et al. 2006 ) 2 . However, less attention has specifically focused on emotion’s impact on the application of critical thought. This may be a result of assumptions that if a person is inclined to think critically, then what is yielded will typically be void of emotion—which is true to a certain extent. However, despite the domain generality of CT ( Dwyer 2011 , 2017 ; Dwyer and Eigenauer 2017 ; Dwyer et al. 2015 ; Gabennesch 2006 ; Halpern 2014 ), the likelihood of emotional control during the CT process remains heavily dependent on the topic of application. Consider again, for example; there is no guarantee that an individual who generally applies CT to important topics or situations will do so in all contexts. Indeed, depending on the nature of the topic or the problem faced, an individual’s mindware ( Clark 2001 ; Stanovich 2018 ; Stanovich et al. 2016 ; consistent with the metacognitive nature of CT) and the extent to which a context can evoke emotion in the thinker will influence what and how thinking is applied. As addressed above, if the topic is something to which the individual feels passionate, then it will more likely be a greater challenge for them to remain unbiased and develop a reasonably objective argument or solution.

Notably, self-regulation is an important aspect of both RJ and CT ( Dwyer 2017 ; Dwyer et al. 2014 ), and, in this context, it is difficult not to consider the role emotional intelligence might play in the relationship between affect and CT. For example, though there are a variety of conceptualisations of emotional intelligence (e.g., Bar-On 2006 ; Feyerherm and Rice 2002 ; Goleman 1995 ; Salovey and Mayer 1990 ; Schutte et al. 1998 ), the underlying thread among these is that, similar to the concept of self-regulation, emotional intelligence (EI) refers to the ability to monitor (e.g., perceive, understand and regulate) one’s own feelings, as well as those of others, and to use this information to guide relevant thinking and behaviour. Indeed, extant research indicates that there is a positive association between EI and CT (e.g., Afshar and Rahimi 2014 ; Akbari-Lakeh et al. 2018 ; Ghanizadeh and Moafian 2011 ; Kaya et al. 2017 ; Stedman and Andenoro 2007 ; Yao et al. 2018 ). To shed light upon this relationship, Elder ( 1997 ) addressed the potential link between CT and EI through her description of the latter as a measure of the extent to which affective responses are rationally-based , in which reasonable desires and behaviours emerge from such rationally-based emotions. Though there is extant research on the links between CT and EI, it is recommended that future research further elaborate on this relationship, as well as with other self-regulatory processes, in an effort to further establish the potentially important role that EI might play within CT.

3. Discussion

3.1. interpretations.

Given difficulties in the past regarding the conceptualisation of CT ( Dwyer et al. 2014 ), efforts have been made to be as specific and comprehensive as possible when discussing CT in the literature to ensure clarity and accuracy. However, it has been argued that such efforts have actually added to the complexity of CT’s conceptualisation and had the opposite effect on clarity and, perhaps, more importantly, the accessibility and practical usefulness for educators (and students) not working in the research area. As a result, when asked what CT is, I generally follow up the ‘long definition’, in light of past research, with a much simpler description: CT is akin to ‘playing devil’s advocate’. That is, once a claim is made, one should second-guess it in as many conceivable ways as possible, in a process similar to the Socratic Method. Through asking ‘why’ and conjecturing alternatives, we ask the individual—be it another person or even ourselves—to justify the decision-making. It keeps the thinker ‘honest’, which is particularly useful if we’re questioning ourselves. If we do not have justifiable reason(s) for why we think or intend to act in a particular way (above and beyond considered objections), then it should become obvious that we either missed something or we are biased. It is perhaps this simplified description of CT that gives such impetus for the aim of this review.

Whereas extant frameworks often discuss the importance of CT skills, dispositions, and, to a lesser extent, RJ and other self-regulatory functions of CT, they do so with respect to components of CT or processes that facilitate CT (e.g., motivation, executive functions, and dispositions), without fully encapsulating cognitive processes and other factors that may hinder it (e.g., emotion, bias, intuitive judgment and a lack of epistemological understanding or engagement). With that, this review is neither a criticism of existing CT frameworks nor is it to imply that CT has so many barriers that it cannot be taught well, nor does it claim to be a complete list of processes that can impede CT (see again Note 1). To reiterate, education in CT can yield beneficial effects ( Abrami et al. 2008 , 2015 ; Dwyer 2017 ; Dwyer and Eigenauer 2017 ); however, such efficacy may be further enhanced by presenting students and individuals interested in CT the barriers they are likely to face in its application; explaining how these barriers manifest and operate; and offer potential strategies for overcoming them.

3.2. Further Implications and Future Research

Though the barriers addressed here are by no means new to the arena of research in higher-order cognition, there is a novelty in their collated discussion as impactful barriers in the context of CT, particularly with respect to extant CT research typically focusing on introducing strategies and skills for enhancing CT, rather than identifying ‘preventative measures’ for barriers that can negatively impact CT. Nevertheless, future research is necessary to address how such barriers can be overcome in the context of CT. As addressed above, it is recommended that CT education include discussion of these barriers and encourage self-regulation against them; and, given the vast body of CT research focusing on enhancement through training and education, it seems obvious to make such a recommendation in this context. However, it is also recognised that simply identifying these barriers and encouraging people to engage in RJ and self-regulation to combat them may not suffice. For example, educators might very well succeed in teaching students how to apply CT skills , but just as these educators may not be able to motivate students to use them as often as they might be needed or even to value such skills (such as in attempting to elicit a positive disposition towards CT), it might be the case that without knowing about the impact of the discussed barriers to CT (e.g., emotion and/or intuitive judgment), students may be just as susceptible to biases in their attempts to think critically as others without CT skills. Thus, what such individuals might be applying is not CT at all; rather, just a series of higher-order cognitive skills from a biased or emotion-driven perspective. As a result, a genuine understanding of these barriers is necessary for individuals to appropriately self-regulate their thinking.

Moreover, though the issues of epistemological beliefs, bias, emotion, and intuitive processes are distinct in the manner in which they can impact CT, these do not have set boundaries; thus, an important implication is that they can overlap. For example, epistemological understanding can influence how individuals make decisions in real-world scenarios, such as through intuiting a judgment in social situations (i.e., without considering the nature of the knowledge behind the decision, the manner in which such knowledge interacts [e.g., correlation v. causation], the level of uncertainty regarding both the decision-maker’s personal stance and the available evidence), when a situation might actually require further consideration or even the honest response of ‘I don’t know’. The latter concept—that of simply responding ‘I don’t know’ is interesting to consider because though it seems, on the surface, to be inconsistent with CT and its outcomes, it is commensurate with many of its associated components (e.g., intellectual honesty and humility; see Paul and Elder 2008 ). In the context this example is used, ‘I don’t know’ refers to epistemological understanding. With that, it may also be impacted by bias and emotion. For example, depending on the topic, an individual may be likely to respond ‘I don’t know’ when they do not have the relevant knowledge or evidence to provide a sufficient answer. However, in the event that the topic is something the individual is emotionally invested in or feels passionate about, an opinion or belief may be shared instead of ‘I don’t know’ (e.g., Kahneman and Frederick 2002 ), despite a lack of requisite evidence-based knowledge (e.g., Kruger and Dunning 1999 ). An emotional response based on belief may be motivated in the sense that the individual knows that they do not know for sure and simply uses a belief to support their reasoning as a persuasive tool. On the other hand, the emotional response based on belief might be used simply because the individual may not know that the use of a belief is an insufficient means of supporting their perspective– instead, they might think that their intuitive, belief-based judgment is as good as a piece of empirical evidence; thus, suggesting a lack of empirical understanding. With that, it is fair to say that though epistemological understanding, intuitive judgment, emotion, and bias are distinct concepts, they can influence each other in real-world CT and decision-making. Though there are many more examples of how this might occur, the one presented may further support the recommendation that education can be used to overcome some of the negative effects associated with the barriers presented.

For example, in Ireland, students are not generally taught about academic referencing until they reach third-level education. Anecdotally, I was taught about referencing at age 12 and had to use it all the way through high school when I was growing up in New York. In the context of these referencing lessons, we were taught about the credibility of sources, as well as how analyse and evaluate arguments and subsequently infer conclusions in light of these sources (i.e., CT skills). We were motivated by our teacher to find the ‘truth’ as best we could (i.e., a fundament of CT disposition). Now, I recognise that this experience cannot be generalised to larger populations, given that I am a sample size of one, but I do look upon such education, perhaps, as a kind of transformative learning experience ( Casey 2018 ; King 2009 ; Mezirow 1978 , 1990 ) in the sense that such education might have provided a basis for both CT and epistemological understanding. For CT, we use research to support our positions, hence the importance of referencing. When a ‘reference’ is not available, one must ask if there is actual evidence available to support the proposition. If there is not, one must question the basis for why they think or believe that their stance is correct—that is, where there is logic to the reasoning or if the proposition is simply an emotion- or bias-based intuitive judgment. So, in addition to referencing, the teaching of some form of epistemology—perhaps early in children’s secondary school careers, might benefit students in future efforts to overcome some barriers to CT. Likewise, presenting examples of the observable impact that bias, emotions, and intuitive thought can have on their thinking might also facilitate overcoming these barriers.

As addressed above, it is acknowledged that we may not be able to ‘teach’ people not to be biased or emotionally driven in their thinking because it occurs naturally ( Kahneman 2011 )—regardless of how ‘skilled’ one might be in CT. For example, though research suggests that components of CT, such as disposition, can improve over relatively short periods of time (e.g., over the duration of a semester-long course; Rimiene 2002 ), less is known about how such components have been enhanced (given the difficulty often associated with trying to teach something like disposition ( Dwyer 2017 ); i.e., to reiterate, it is unlikely that simply ‘teaching’ (or telling) students to be motivated towards CT or to value it (or its associated concepts) will actually enhance it over short periods of time (e.g., semester-long training). Nevertheless, it is reasonable to suggest that, in light of such research, educators can encourage dispositional growth and provide opportunities to develop it. Likewise, it is recommended that educators encourage students to be aware of the cognitive barriers discussed and provide chances to engage in CT scenarios where such barriers are likely to play a role, thus, giving students opportunities to acknowledge the barriers and practice overcoming them. Moreover, making students aware of such barriers at younger ages—in a simplified manner, may promote the development of personal perspectives and approaches that are better able to overcome the discussed barriers to CT. This perspective is consistent with research on RJ ( Dwyer et al. 2015 ), in which it was recommended that such enhancement requires not only time to develop (be it over the course of a semester or longer) but is also a function of having increased opportunities to engage CT. In the possibilities described, individuals may learn both to overcome barriers to CT and from the positive outcomes of applying CT; and, perhaps, engage in some form of transformative learning ( Casey 2018 ; King 2009 ; Mezirow 1978 , 1990 ) that facilitates an enhanced ‘valuing’ of and motivation towards CT. For example, through growing an understanding of the nature of epistemology, intuitive-based thinking, emotion, bias, and the manner in which people often succumb to faulty reasoning in light of these, individuals may come to better understand the limits of knowledge, barriers to CT and how both understandings can be applied; thus, growing further appreciation of the process as it is needed.

To reiterate, research suggests that there may be a developmental trajectory above and beyond the parameters of a semester-long training course that is necessary to develop the RJ necessary to think critically and, likewise, engage an adequate epistemological stance and self-regulate against impeding cognitive processes ( Dwyer et al. 2015 ). Though such research suggests that such development may not be an issue of time, but rather the amount of opportunities to engage RJ and CT, there is a dearth of recommendations offered with respect to how this could be performed in practice. Moreover, the how and what regarding ‘opportunities for engagement’ requires further investigation as well. For example, does this require additional academic work outside the classroom in a formal manner, or does it require informal ‘exploration’ of the world of information on one’s own? If the latter, the case of motivational and dispositional levels once again comes into question; thus, even further consideration is needed. One way or another, future research efforts are necessary to identify how best to make individuals aware of barriers to CT, encourage them to self-regulate against them, and identify means of increasing opportunities to engage RJ and CT.

4. Conclusions

Taking heed that it is unnecessary to reinvent the CT wheel ( Eigenauer 2017 ), the aim of this review was to further elaborate on the processes associated with CT and make a valuable contribution to its literature with respect to conceptualisation—not just in light of making people explicitly aware of what it is, but also what it is not and how it can be impeded (e.g., through inadequate CT skills and dispositions; epistemological misunderstanding; intuitive judgment; as well as bias and emotion)—a perspective consistent with that of ‘constructive feedback’ wherein students need to know both what they are doing right and what they are doing wrong. This review further contributes to the CT education literature by identifying the importance of (1) engaging understanding of the nature, limits, and certainty of knowing as individuals traverse the landscape of evidence-bases in their research and ‘truth-seeking’; (2) understanding how emotions and biases can affect CT, regardless of the topic; (3) managing gut-level intuition until RJ has been appropriately engaged; and (4) the manner in which language is used to convey meaning to important and/or abstract concepts (e.g., ‘caring’, ‘proof’, causation/correlation, etc.). Consistent with the perspectives on research advancement presented in this review, it is acknowledged that the issues addressed here may not be complete and may themselves be advanced upon and updated in time; thus, future research is recommended and welcomed to improve and further establish our working conceptualisation of critical thinking, particularly in a real-world application.

1 Notably, though inadequacies in cognitive resources (apart from those explicitly set within the conceptualisations of CT discussed; e.g., see Section 2.1 ) are acknowledged as impediments to one’s ability to apply CT (e.g., a lack of relevant background knowledge, as well as broader cognitive abilities and resources ( Dwyer 2017 ; Halpern 2014 ; Stanovich and Stanovich 2010 )), these will not be discussed as focus is largely restricted to issues of cognitive processes that ‘naturally’ act as barriers in their functioning. Moreover, such inadequacies may more so be issues of individual differences than ongoing issues that everyone , regardless of ability, would face in CT (e.g., the impact of emotion and bias). Nevertheless, it is recommended that future research further investigates the influence of such inadequacies in cognitive resources on CT.

2 There is also some research that suggests that emotion may mediate enhanced cognition ( Dolcos et al. 2011 , 2012 ). However, this discrepancy in findings may result from the types of emotion studied—such as task-relevant emotion and task-irrelevant emotion. The distinction between the two is important to consider in terms of, for example, the distinction between one’s general mood and feelings specific unto the topic under consideration. Though mood may play a role in the manner in which CT is conducted (e.g., making judgments about a topic one is passionate about may elicit positive or negative emotions that affect the thinker’s mood in some way), notably, this discussion focuses on task-relevant emotion and associated biases that negatively impact the CT process. This is also an important distinction because an individual may generally think critically about ‘important’ topics, but may fail to do so when faced with a cognitive task that requires CT with which the individual has a strong, emotional perspective (e.g., in terms of passion , as described above).

The Key to Inclusive Leadership

• Juliet Bourke
• Andrea Titus

Overcome unconscious bias using humility and empathy.

Inclusive leadership is emerging as a unique and critical capability helping organisations adapt to diverse customers, markets, ideas and talent. For those working around a leader, such as a manager, direct report or peer, the single most important trait generating a sense of inclusiveness is a leader’s visible awareness of bias. But to fully capitalize on their cognizance of bias, leaders also must express both humility and empathy. This article describes organizational practices that can help leaders become more inclusive and enhance the performance of their teams.

What makes people feel included in organizations? Feel that they are treated fairly and respectfully, are valued and belong? Many things of course, including an organization’s mission, policies, and practices, as well as co-worker behaviors.

What is Critical Thinking in Academics – Guide With Examples

Published by Grace Graffin at October 17th, 2023 , Revised On October 17, 2023

In an era dominated by vast amounts of information, the ability to discern, evaluate, and form independent conclusions is more crucial than ever. Enter the realm of “critical thinking.” But what does this term truly mean? 

What is Critical Thinking?

Critical thinking is the disciplined art of analysing and evaluating information or situations by applying a range of intellectual skills. It goes beyond mere memorisation or blind acceptance of information, demanding a deeper understanding and assessment of evidence, context, and implications.

Moreover, paraphrasing in sources is an essential skill in critical thinking, as it allows for representing another’s ideas in one’s own words, ensuring comprehension.

Critical thinking is not just an academic buzzword but an essential tool. In academic settings, it serves as the backbone of genuine understanding and the springboard for innovation. When students embrace critical thinking, they move from being passive recipients of information to active participants in their own learning journey.

They question, evaluate, and synthesise information from various sources, fostering an intellectual curiosity that extends beyond the classroom. Part of this involves understanding how to integrate sources into their work, which means not only including information from various places, but also doing so in a cohesive and logical way.

The importance of critical thinking in academics cannot be overstated. It equips students with the skills to discern credible sources from unreliable ones, develop well-informed arguments, and approach problems with a solution-oriented mindset.

The Origins and Evolution of Critical Thinking

The idea of critical thinking isn’t a new-age concept. Its roots reach back into ancient civilisations, moulding the foundations of philosophy, science, and education. To appreciate its evolution, it’s vital to delve into its historical context and the influential thinkers who have championed it.

Historical Perspective on the Concept of Critical Thinking

The seeds of critical thinking can be traced back to Ancient Greece, particularly in the city-state of Athens. Here, the practice of debate, dialogue, and philosophical inquiry was valued and was seen as a route to knowledge and wisdom. This era prized the art of questioning, investigating, and exploring diverse viewpoints to reach enlightened conclusions.

In medieval Islamic civilisation, scholars in centres of learning, such as the House of Wisdom in Baghdad, played a pivotal role in advancing critical thought. Their works encompassed vast areas, including philosophy, mathematics, and medicine, often intertwining rigorous empirical observations with analytical reasoning.

The Renaissance period further nurtured critical thinking as it was a time of revival in art, culture, and intellect. This era championed humanistic values, focusing on human potential and achievements. It saw the rebirth of scientific inquiry, scepticism about religious dogma, and an emphasis on empirical evidence.

Philosophers and Educators Who Championed Critical Thinking

Several philosophers and educators stand out for their remarkable contributions to the sphere of critical thinking:

Known for the Socratic method, a form of cooperative argumentative dialogue, Socrates would ask probing questions, forcing his pupils to think deeply about their beliefs and assumptions. His methodology still influences modern education, emphasising the answer and the path of reasoning that leads to it.

A student of Socrates, Plato believed in the importance of reason and inquiry. His allegory of the cave highlights the difference between blindly accepting information and seeking true knowledge.

He placed great emphasis on empirical evidence and logic. His works on syllogism and deductive reasoning laid the foundation for systematic critical thought.

Al-Farabi And Ibn Rushd (Averroes)

Islamic philosophers, who harmonised Greek philosophy with Islamic thought, emphasised the importance of rationality and critical inquiry.

Sir Francis Bacon

An advocate for the scientific method, Bacon believed that knowledge should be based on empirical evidence, observation, and experimentation rather than mere reliance on accepted truths.

A modern proponent of critical thinking, Dewey viewed it as an active, persistent, and careful consideration of a belief or supposed form of knowledge. He emphasised that students should be taught to think for themselves rather than just memorise facts.

Paulo Freire

Recognised for his ideas on “problem-posing education,” Freire believed that students should be encouraged to question, reflect upon, and respond to societal issues, fostering critical consciousness.

Characteristics of Critical Thinkers

Critical thinkers are not defined merely by the knowledge they possess, but by the manner in which they process, analyse, and use that knowledge. While the profile of a critical thinker can be multifaceted, certain core traits distinguish them. Let’s delve into these characteristics:

1. Open-mindedness

Open-mindedness refers to the willingness to consider different ideas, opinions, and perspectives, even if they challenge one’s existing beliefs. It allows critical thinkers to avoid being trapped in their own biases or preconceived notions. By being open to diverse viewpoints, they can make more informed and holistic decisions.

• Listening to a debate without immediately taking sides.
• Reading literature from different cultures to understand various world views.

2. Analytical Nature

An analytical nature entails the ability to break down complex problems or information into smaller, manageable parts to understand the whole better. Being analytical enables individuals to see patterns, relationships, and inconsistencies, allowing for deeper comprehension and better problem-solving.

• Evaluating a research paper by examining its methodology, results, and conclusions separately.
• Breaking down the components of a business strategy to assess its viability.

3. Scepticism

Scepticism is the tendency to question and doubt claims or assertions until sufficient evidence is presented. Skepticism ensures that critical thinkers do not accept information at face value. They seek evidence and are cautious about jumping to conclusions without verification.

• Questioning the results of a study that lacks a control group.
• Doubting a sensational news headline and researching further before believing or sharing it.

4. Intellectual Humility

Intellectual humility involves recognising and accepting the limitations of one’s knowledge and understanding. It is about being aware that one does not have all the answers. This trait prevents arrogance and overconfidence. Critical thinkers with intellectual humility are open to learning and receptive to constructive criticism.

• Admitting when one is wrong in a discussion.
• Actively seeking feedback on a project or idea to enhance it.

5. Logical Reasoning

Logical reasoning is the ability to think sequentially and make connections between concepts in a coherent manner. It involves drawing conclusions that logically follow from the available information. Logical reasoning ensures that decisions and conclusions are sound and based on valid premises. It helps avoid fallacies and cognitive biases.

• Using deductive reasoning to derive a specific conclusion from a general statement.
• Evaluating an argument for potential logical fallacies like “slippery slope” or “ad hominem.”

The Difference Between Critical Thinking and Memorisation

In today’s rapidly changing educational landscape, there is an ongoing debate about the importance of rote memorisation versus the significance of cultivating critical thinking skills. Both have their place in learning, but they serve very different purposes.

Nature Of Learning

• Rote Learning: Involves memorising information exactly as it is, without necessarily understanding its context or underlying meaning. It’s akin to storing data as-is, without processing.
• Analytical Processing (Critical Thinking): Involves understanding, questioning, and connecting new information with existing knowledge. It’s less about storage and more about comprehension and application.

Depth of Engagement

• Rote Learning: Often remains at the surface level. Students might remember facts for a test, but might forget them shortly after.
• Analytical Processing: Engages deeper cognitive skills. When students think critically, they’re more likely to retain information because they’ve processed it deeper.

Application in New Situations

• Rote Learning: Information memorised through rote often does not easily apply to new or unfamiliar situations, since it is detached from understanding.
• Analytical Processing: Promotes adaptability. Critical thinkers can transfer knowledge and skills to different contexts because they understand underlying concepts and principles.

Why Critical Thinking Produces Long-Term Academic Benefits

Here are the benefits of critical thinking in academics. 

Enhanced Retention

Critical thinking often involves active learning—discussions, problem-solving, and debates—which promotes better retention than passive memorisation.

Skill Development

Beyond content knowledge, critical thinking develops skills like analysis, synthesis, source evaluation , and problem-solving. These are invaluable in higher education and professional settings.

Adaptability

In an ever-evolving world, the ability to adapt is crucial. Critical thinkers are better equipped to learn and adapt because they don’t just know facts; they understand concepts.

Lifelong Learning

Critical thinkers are naturally curious. They seek to understand, question, and explore, turning them into lifelong learners who continually seek knowledge and personal growth.

Improved Decision-Making

Analytical processing allows students to evaluate various perspectives, weigh evidence, and make well-informed decisions, a skill far beyond academics.

Preparation for Real-World Challenges

The real world does not come with a textbook. Critical thinkers can navigate unexpected challenges, connect disparate pieces of information, and innovate solutions.

Steps in the Critical Thinking Process

Critical thinking is more than just a skill—it is a structured process. By following a systematic approach, critical thinkers can navigate complex issues and ensure their conclusions are well-informed and reasoned. Here’s a breakdown of the steps involved:

Step 1. Identification and Clarification of the Problem or Question

Recognizing that a problem or question exists and understanding its nature. It’s about defining the issue clearly, without ambiguity. A well-defined problem serves as the foundation for the subsequent steps. The entire process may become misguided without a clear understanding of what’s being addressed.

Example: Instead of a vague problem like “improving the environment,” a more specific question could be “How can urban areas reduce air pollution?”

Step 2. Gathering Information and Evidence

Actively seeking relevant data, facts, and evidence. This might involve research, observations, experiments, or discussions. Reliable decisions are based on solid evidence. The quality and relevance of the information gathered can heavily influence the final conclusion.

Example: To address urban air pollution, one might gather data on current pollution levels, sources of pollutants, existing policies, and strategies employed by other cities.

Step 3. Analysing the Information

Breaking down the gathered information, scrutinising its validity, and identifying patterns, contradictions, and relationships. This step ensures that the information is not just accepted at face value. Critical thinkers can differentiate between relevant and irrelevant information and detect biases or inaccuracies by analysing data.

Example: When examining data on pollution, one might notice that certain industries are major contributors or that pollution levels rise significantly at specific times of the year.

Step 4. Drawing Conclusions and Making Decisions

After thorough analysis, formulating an informed perspective, solution, or decision-based on the evidence. This is the culmination of the previous steps. Here, the critical thinker synthesises the information and applies logic to arrive at a reasoned conclusion.

Example: Based on the analysis, one might conclude that regulating specific industries and promoting public transportation during peak pollution periods can help reduce urban air pollution.

Step 5. Reflecting on the Process And The Conclusions Reached

Take a step back to assess the entire process, considering any potential biases, errors, or alternative perspectives. It is also about evaluating the feasibility and implications of the conclusions. Reflection ensures continuous learning and improvement. Individuals can refine their approach to future problems by evaluating their thinking process.

Example: Reflecting on the proposed solution to reduce pollution, one might consider its economic implications, potential industry resistance, and the need for public awareness campaigns.

The Role of Critical Thinking in Different Academic Subjects

Critical thinking is a universal skill applicable across disciplines. Its methodologies might differ based on the subject, but its core principles remain consistent. Let us explore how critical thinking manifests in various academic domains:

1. Sciences

• Hypothesis Testing: Science often begins with a hypothesis—a proposed explanation for a phenomenon. Critical thinking is essential in formulating a testable hypothesis and determining its validity based on experimental results.
• Experimental Design: Designing experiments requires careful planning to ensure valid and reliable results. Critical thinking aids in identifying variables, ensuring controls, and determining the best methodologies to obtain accurate data.
• Example: In a biology experiment to test the effect of light on plant growth, critical thinking helps ensure variables like water and soil quality are consistent, allowing for a fair assessment of the light’s impact.

2. Humanities

• Analysing Texts: Humanities often involve studying texts—literature, historical documents, or philosophical treatises. Critical thinking lets students decode themes, discern authorial intent, and recognise underlying assumptions or biases.
• Understanding Contexts: Recognizing a text or artwork’s cultural, historical, or social contexts is pivotal. Critical thinking allows for a deeper appreciation of these contexts, providing a holistic understanding of the subject.
• Example: When studying Shakespeare’s “Othello,” critical thinking aids in understanding the play’s exploration of jealousy, race, and betrayal, while also appreciating its historical context in Elizabethan England.

3. Social Sciences

• Evaluating Arguments: Social sciences, such as sociology or political science, often present various theories or arguments about societal structures and behaviours. Critical thinking aids in assessing the merits of these arguments and recognising their implications.
• Understanding Biases: Since social sciences study human societies, they’re susceptible to biases. Critical thinking helps identify potential biases in research or theories, ensuring a more objective understanding.
• Example: In studying economic policies, critical thinking helps weigh the benefits and drawbacks of different economic models, considering both empirical data and theoretical arguments.

4. Mathematics

• Problem-Solving: Mathematics is more than just numbers; it is about solving problems. Critical thinking enables students to identify the best strategies to tackle problems, ensuring efficient and accurate solutions.
• Logical Deduction: Mathematical proofs and theorems rely on logical steps. Critical thinking ensures that each step is valid and the conclusions sound.
• Example: In geometry, when proving that two triangles are congruent, critical thinking helps ensure that each criterion (like side lengths or angles) is met and the logic of the proof is coherent.

Examples of Critical Thinking in Academics

Some of the critical thinking examples in academics are discussed below. 

Case Study 1: Evaluating A Scientific Research Paper

Scenario: A research paper claims that a new herbal supplement significantly improves memory in elderly individuals.

Critical Thinking Application:

Scrutinising Methodology:

• Was the study double-blind and placebo-controlled?
• How large was the sample size?
• Were the groups randomised?
• Were there any potential confounding variables?

Assessing Conclusions:

• Do the results conclusively support the claim, or are there other potential explanations?
• Are the statistical analyses robust, and do they show a significant difference?
• Is the effect size clinically relevant or just statistically significant?

Considering Broader Context:

• How does this study compare with existing literature on the subject?
• Were there any conflicts of interest, such as funding from the supplement company?

Critical analysis determined that while the study showed statistical significance, the effect size was minimal. Additionally, the sample size was small, and there was potential bias as the supplement manufacturer funded the study.

Case Study 2: Analysing a Literary Text

Scenario: A reading of F. Scott Fitzgerald’s “The Great Gatsby.”

Understanding Symbolism:

• What does the green light represent for Gatsby and in the broader context of the American Dream?
• How does the Valley of Ashes symbolise societal decay?

Recognising Authorial Intent:

• Why might Fitzgerald depict the characters’ lavish lifestyles amid underlying dissatisfaction?
• What critiques of American society is Fitzgerald potentially making?

Contextual Analysis:

• How does the era in which the novel was written (Roaring Twenties) influence its themes and characters?

Through critical analysis, the reader recognises that while “The Great Gatsby” is a tale of love and ambition, it’s also a poignant critique of the hollowness of the American Dream and the societal excesses of the 1920s.

Case Study 3: Decoding Historical Events

Scenario: The events leading up to the American Revolution.

Considering Multiple Perspectives:

• How did the British government view the colonies and their demands?
• What were the diverse perspectives within the American colonies, considering loyalists and patriots?

Assessing Validity of Sources:

• Which accounts are primary sources, and which are secondary?
• Are there potential biases in these accounts, based on their origins?

Analysing Causation and Correlation:

• Were taxes and representation the sole reasons for the revolution, or were there deeper economic and philosophical reasons?

Through critical analysis, the student understands that while taxation without representation was a significant catalyst, the American Revolution was also influenced by Enlightenment ideas, economic interests, and long-standing grievances against colonial policies.

Challenges to Developing Critical Thinking Skills

In our complex and rapidly changing world, the importance of critical thinking cannot be overstated. However, various challenges can impede the cultivation of these vital skills. 

1. Common Misconceptions and Cognitive Biases

Human brains often take shortcuts in processing information, leading to cognitive biases. Additionally, certain misconceptions about what constitutes critical thinking can hinder its development.

• Confirmation Bias: The tendency to search for, interpret, and recall information that confirms one’s pre-existing beliefs.
• Anchoring Bias: Relying too heavily on the first piece of information encountered when making decisions.
• Misconception: Believing that critical thinking merely means being critical or negative about ideas, rather than evaluating them objectively.

These biases can skew perception and decision-making, making it challenging to objectively approach issues.

2. The Influence of Technology and Social Media

While providing unprecedented access to information, the digital age also presents unique challenges. The barrage of information, the immediacy of social media reactions, and algorithms that cater to user preferences can hinder critical thought.

• Information Overload: The sheer volume of online data can make it difficult to discern credible sources from unreliable ones.
• Clickbait and Misinformation: Articles with sensational titles designed to generate clicks might lack depth or accuracy.
• Algorithmic Bias: Platforms showing users content based on past preferences can limit exposure to diverse viewpoints.

Relying too heavily on technology and social media can lead to superficial understanding, reduced attention spans, and a narrow worldview.

3. The Danger of Echo Chambers and Confirmation Bias

An echo chamber is a situation in which beliefs are amplified or reinforced by communication and repetition inside a closed system, cutting off differing viewpoints.

• Social Media Groups: Joining groups or following pages that only align with one’s beliefs can create a feedback loop, reinforcing existing opinions without challenge.
• Selective Media Consumption: Only watching news channels or reading websites that align with one’s political or social views.

Echo chambers reinforce confirmation bias, limit exposure to diverse perspectives, and can polarise opinions, making objective, critical evaluation of issues challenging.

Benefits of Promoting Critical Thinking in Education

When cultivated and promoted in educational settings, critical thinking can have transformative effects on students, equipping them with vital skills to navigate their academic journey and beyond. Here’s an exploration of the manifold benefits of emphasising critical thinking in education:

Improved Problem-Solving Skills

Critical thinking enables students to approach problems methodically, breaking them down into manageable parts, analysing each aspect, and synthesising solutions.

• Academic: Enhances students’ ability to tackle complex assignments, research projects, and unfamiliar topics.
• Beyond School: Prepares students for real-world challenges where they might encounter problems without predefined solutions.

Enhanced Creativity and Innovation

Critical thinking is not just analytical but also involves lateral thinking, helping students see connections between disparate ideas and encouraging imaginative solutions.

• Academic: Promotes richer discussions, more creative projects, and the ability to view topics from multiple angles.
• Beyond School: Equips students for careers and situations where innovative solutions can lead to advancements in fields like technology, arts, or social entrepreneurship.

With an inclusive mindset comes powerful perspectives

Becoming a more inclusive leader is easier said than done. Learn the 4 steps you can take to develop a more inclusive mindset today.

As the world becomes more complex and social and human justice issues take center stage, leaders are being called on to do more and be better.

But the most successful leaders aren't just hiring more diverse talent, they're approaching their business with an inclusive mindset. They're bringing multiple, diverse perspectives to the table and creating environments where everyone feels empowered to influence decision-making. They're recognizing how inclusion in the workplace can lead to social equity and better business outcomes. They're reflecting on themselves and serving others.

At Korn Ferry, we call this inclusive mindset "inclusion that multiplies". It is one of the five leadership mindsets that enable business leaders to grow their capabilities and become true Enterprise Leaders . This mindset helps you achieve better results and decision-making through connection, collectivity and collaboration.

What is "inclusion that multiplies"?

It's easy to think that inclusion is simply hiring more people from different demographics and backgrounds or bringing more people into business meetings. Inclusion is often oversimplified into additive terms.

Inclusion that multiplies is broader. It's not only about peoples' presence or even participation. This inclusive mindset is about making sure diverse perspectives are actually heard, understood, and applied; that decisions are reached collaboratively; and that different perspectives influence decision-making in an ongoing way. It's the magic that makes a group more than the sum of its parts.

Many successful leaders are advocates and allies for inclusion, such as Alphabet and Google CEO Sundar Pichai, who says, "A diverse mix of voices leads to better discussions, decisions, and outcomes for everyone." Enterprise Leaders not only gather that diverse mix of voices, but they also realize that no single person can capture the complexities of every corner of the business. They know that the best way to succeed is to give up a bit of power and enable their network of leaders to share information, ask questions to gain perspective, make decisions and solve problems collaboratively .

Naomi Sutherland , a Managing Partner at Korn Ferry, says this mindset is more than beneficial—it's freeing. It expands your mind and helps you "think about who should be here, whose perspective do we need, what value is added by different voices," she says. It allows you to consider points of view outside your own and empowers you to make decisions for the whole.

Inclusive mindsets unleash the power of diverse teams

A strong argument for inclusion in the workplace is the power it has to release the collective intelligence of diverse teams. It's the principle behind democracy, trial by jury and academic peer review. Even before it was fully understood as a scientific concept, humans were intuitively aware that better decisions are made by groups, not individuals.

Studies by Anita Williams Woolley , an associate professor of organizational behavior and theory at Carnegie Mellon, have shown that the collective intelligence of a particular group is not strongly correlated with the individual intelligence of its members. But Woolley and her fellow researchers found three factors that do correlate with collective intelligence: the number of different speakers in a group, the proportion of women in a group and the average social sensitivity score for group members.

As a business leader, harnessing the power of collective intelligence means harnessing these factors of collective intelligence by fostering a socially sensitive, diverse and inclusive "environment where everyone has opportunity to share equally," Sutherland says. It means understanding that "intelligence" refers not only to the expertise each person in the room brings to the table but also to the emotional intelligence that enables the group to learn from one another.

"The diverse teams that are most effective in harnessing collective intelligence are able to read the emotions of others in the room," Sutherland says. Team members are able to share their own perspectives and know when it's time to shift the floor to others.

So how can you adopt an inclusion that multiplies mindset and embrace Enterprise Leadership?

Diversity, Equity & Inclusion

Unleashing the power of all of us.

• 4 ways to adopt an inclusive mindset

1 Reflect on your team's current performance

Start by evaluating how well you currently harness collective intelligence in your organization. Recall a recent meeting of your executive team and ask yourself:

• What was the purpose of this team and meeting?
• Who was present in the meeting? Who was the most vocal? Whose voice was loudest?
• Who did we not hear from who may have meaningful insight to share?
• What does this team achieve together that cannot be achieved separately by individual function leaders?
• What is accomplished that would not be done if this team did not come together?

If these questions are difficult to answer, it can be a sign that your group is not as inclusive as it could be, which could be impacting its performance. Sometimes, executive leadership team meetings are simply times for individuals to share what they have been doing within their function. If this is the case, you are benefiting incrementally from the presence of each person, but you have not tapped into the multiplying power of inclusion.

To do better, you need to look at both the structure of the team you've put together and the environment you've created for it to operate.

2 Create inclusive environments

It's not enough just to bring the right people to the table. The role of an Enterprise Leader is to create an environment where people are encouraged to share their perspectives and then ensure those voices are included in the decisions. The collective intelligence of a group increases when more people take a turn speaking.

Applying an inclusive mindset means acknowledging and avoiding the "similar to me" bias in which people tend to value perspectives closest to their own. It also means resisting the urge to assume you know what another person's view will be or thinking you've gathered enough information after listening to only a limited number of perspectives or have sought out or heard primarily from those with whom we already agree. We can't know if that's the case unless we continue listening.

Ellevest CEO Sallie Krawcheck notes that hiring is one area where this bias can creep in. Krawcheck places a high value on hiring a good fit for the whole team rather than just the role because that can unconsciously lead you to select someone who's similar to you. "By trying to hire the right person for the team," she says, "that can drive you to someone with skills and experience and background that are different from the team—and therefore add to the team."

Watching out for the "similar to me" bias in all areas of problem-solving can not only help your teams come to better decisions, but it will also help to create the type of place that people want to work, which can improve hiring prospects and employee retention.

3 Understand your role—and let go of control

To completely adopt an inclusive mindset, you must look inward. You may need to rethink some of your existing assumptions about yourself and your role as a leader.

Some people struggle to let go of the notion that a leader should be a gifted individual, who is an expert at producing brilliant ideas and innovations all on their own. But it’s far more likely that a leader gained their strength by working with others over time and that their innovations are built on the ideas of others in an environment where people feel a sense of appreciation and openness.

Instead, accept that you cannot be an expert at everything—that you can achieve much more by including and empowering other people and amplifying their voices. Your role is to bring people together, share the challenge and listen before making a final decision in the best interests of the group. This inevitably means letting go of control and distributing power to others.

When you give up some control over problem-solving and decision-making, you empower others to share their ideas. It multiplies the impact your collectivity can have.

4 Look beyond your organization

Using inclusion as a force multiplier shouldn't stop at the boundary of your organization. "It's hard to have innovative ideas if you're not talking to people outside your organization," Sutherland says. Many leaders keep their knowledge and views close to the vest. But an important aspect of Enterprise Leadership is looking to create lasting change not just across your organization but beyond it—into the ecosystem and society you exist in.

As one example, think of the teams of scientists and researchers at pharmaceutical companies that came together to collaborate on a vaccine for COVID-19. These companies not only worked with each other for the greater good, but also included outside expertise to enable fast success. Through a radically inclusive approach, they were able to multiply their resources and ambition far beyond what a single person or department or even an organization could achieve. You can have a similar influence if you, too, open up the limits on collaboration.

It's this outside network that can truly help an organization thrive, says Sutherland. For leaders, Sutherland notes, "understanding what's going on in their industry [and], who’s doing similar and aligned work, having relationships with seeming competitors, sharing data and insights, being sure they're not working in isolation" can make all the difference.

Develop your inclusive mindset

Challenging your belief systems and adopting new mindsets is not easy to do. It's all part of the ongoing journey to become a true Enterprise Leader who possesses the skills necessary to take on the multifaceted challenges of today's business world.

Critical thinking definition

Critical thinking, as described by Oxford Languages, is the objective analysis and evaluation of an issue in order to form a judgement.

Active and skillful approach, evaluation, assessment, synthesis, and/or evaluation of information obtained from, or made by, observation, knowledge, reflection, acumen or conversation, as a guide to belief and action, requires the critical thinking process, which is why it's often used in education and academics.

Some even may view it as a backbone of modern thought.

However, it's a skill, and skills must be trained and encouraged to be used at its full potential.

People turn up to various approaches in improving their critical thinking, like:

• Developing technical and problem-solving skills
• Engaging in more active listening
• Actively questioning their assumptions and beliefs
• Seeking out more diversity of thought
• Opening up their curiosity in an intellectual way etc.

Is critical thinking useful in writing?

Critical thinking can help in planning your paper and making it more concise, but it's not obvious at first. We carefully pinpointed some the questions you should ask yourself when boosting critical thinking in writing:

• What information should be included?
• Which information resources should the author look to?
• What degree of technical knowledge should the report assume its audience has?
• What is the most effective way to show information?
• How should the report be organized?
• How should it be designed?
• What tone and level of language difficulty should the document have?

Usage of critical thinking comes down not only to the outline of your paper, it also begs the question: How can we use critical thinking solving problems in our writing's topic?

Let's say, you have a Powerpoint on how critical thinking can reduce poverty in the United States. You'll primarily have to define critical thinking for the viewers, as well as use a lot of critical thinking questions and synonyms to get them to be familiar with your methods and start the thinking process behind it.

Are there any services that can help me use more critical thinking?

Measuring well-being and progress

GDP is a well-established tool for measuring economic output, but it does not tell us whether life as a whole is getting better, and for whom. The OECD Well-being Framework helps to monitor societal progress “beyond GDP” and is informing people-centric and integrated policy making across the many dimensions that matter for people, the planet and future generations. The Framework provides a compass to understand how human well-being is evolving in the context of the ecological and digital transitions, and what key actions are needed to support it.

• Well-being frameworks for people-focused policies
• OECD World Forums on Well-being

Select a language

Key messages, improving people’s well-being requires balancing economic, social and environmental objectives and focusing on relationships and social connectedness.

Assessing the well-being of individuals, communities and societies requires looking at multiple aspects that matter for people’s lives. This holistic perspective is even more relevant in a context of fast societal changes. The OECD Well-being Framework considers current well-being outcomes – and inequalities in these – to capture the material conditions that shape people’s economic options, their quality of life, and their relationships. The Framework also includes the systemic resources that are needed to sustain well-being in the future and within planetary and social boundaries. The Framework can support governments and other actors to design policies that promote synergies between economic, social and environmental goals and that put a primary focus on promoting mental health at individual and community level.

The OECD collects statistics on the key components of well-being to monitor people’s quality of life and relational well-being in the context of the digital, demographic and green transitions and to help countries understand whether life is getting better and whether the benefits of progress are being shared equally.

Countries have started to collect internationally harmonised statistics on well-being and should expand this practice further

Frequent, timely and high-quality data on well-being is essential to inform policy decisions. The OECD is advancing the statistical agenda by supporting data producers with methodological guidance on new frontiers of well-being measurement, including subjective well-being, trust, mental health and social connectedness. Although more work remains to be done, this has helped to close data gaps, especially in dimensions of life where internationally harmonised well-being data is most scarce.

The OECD is continuing to update its advice to reflect the latest evidence. For instance, the 2013 Guidelines on Measuring Subjective Well-being are currently being expanded to include guidance on child subjective well-being as well as more globally inclusive measures. 

A well-being lens can bring a more integrated perspective to policy challenges, such as mental health

Mental health affects every aspect of life and is influenced by people’s economic, social and environmental living conditions. However, despite mental health’s strong interactions with factors such as income, education, employment and the environment, integrated approaches across government departments remain limited or small-scale. Reasons include inter-departmental task forces often being time-limited and without decision-making power and resource constraints remain a challenge.

The OECD uses a well-being lens to underscore the reciprocal relationships between mental health and socio-economic outcomes and shows how policies to promote mental health can contribute to achieving other social, economic and environmental policy goals.

OECD governments are increasingly using well-being evidence to inform their policy practices

The real pressure test for well-being initiatives is whether they will be able to graduate from “yet another report” to tangibly influencing government decision-making, and ultimately, people’s quality of life. Multidimensional well-being frameworks and concepts are increasingly being employed by OECD countries in budgeting, policy appraisal and evaluation, strategic coordination, and performance management. Mainstreaming well-being in policy is not a simple add-on to existing practice: it requires and supports new ways of thinking and acting that are more people-focused, more long-term and more joined-up across economic, social, and environmental policy objectives.

In 2023, the OECD launched the Knowledge Exchange Platform on Well-being Metrics and Policy Practice to provide a space for sharing experiences and solutions and to support governments interested in developing policy-focused well-being initiatives. 

How’s life in your country?

The OECD has developed innovative data visualisations that help to illustrate each country’s relative well-being strengths and weaknesses across themes like income, work and job quality, housing conditions, health, safety, social connectedness and civic engagement. The longer a bar in the “well-being wheel”, the better the outcomes in a specific area of well-being, compared to other OECD countries.

Mental health shapes many aspects of life

The OECD used the dimensions of its Well-being Framework to illustrate how economic, social and environmental outcomes intersect with mental health. People experiencing worse mental health tend to fare far worse in most other aspects of their well-being. For example, compared to the general population, those at risk of mental distress are nearly twice as likely to be at the bottom of the income distribution, to be unemployed, or to be unhappy with how they spend their time; their risk for feeling lonely is more than four times greater.
