Critical Thinking: What It Is and Why It Matters

Critical thinking springs from the notion of reflective thought proposed by Dewey (1933), who borrowed from the work of philosophers such as William James and Charles Peirce. Reflective thought was defined as the process of suspending judgment, remaining open-minded, maintaining a healthy skepticism, and taking responsibility for one’s own development (Gerber et al., 2005; Stoyanov & Kirshner, 2007).

Kurland (1995) suggested, “Critical thinking is concerned with reason, intellectual honesty, and open-mindedness, as opposed to emotionalism, intellectual laziness, and closed-mindedness. Thus, critical thinking involves… considering all possibilities… being precise; considering a variety of possible viewpoints and explanations; weighing the effects of motives and biases; being concerned more with finding the truth than with being right…being aware of one’s own prejudices and biases” (p. 3). Thus, being able to perspective-take and becoming conscious of one’s own biases are potential benefits of critical thinking capacities.

Reviews of the critical thinking literature (e.g., Bensley, 2023) suggest that the assessment of this construct ought to include aspects of motivational dispositions. Numerous frameworks of critical thinking dispositions have been proposed (e.g., Bensley, 2018; Butler & Halpern, 2019; Dwyer, 2017); some commonly identified dispositions are open-mindedness, intellectual engagement, and a proclivity to take a reflective stance or approach to evaluating information and the views and beliefs of both oneself and others. Demir (2022) posited that critical thinking dispositions reflect persons’ attitudes toward and routine ways of responding to new information and diverging ideas, willingness to engage in nuanced and complex rather than either/or reductionistic thinking, and perseverance in attempts to understand and resolve complex problems.

Other examples of dispositions are inquisitiveness, open-mindedness, tolerance for ambiguity, thinking about thinking, honesty in assessing or evaluating biases, and willingness to reconsider one’s own views and ways of doing things (Facione et al., 2001). Individual personality attributes associated with these proclivities include a need for cognition (a desire for intellectual stimulation), which is positively associated with critical thinking, and the need for closure (a motivated cognitive style in which individuals prefer predictability, firm answers, and rapid decision making) and anti-intellectualism (a resentment of “the life of the mind” and those who represent it), both negatively associated with critical thinking.

Further, an ideological component that can impede critical thinking is dogmatism. In addition, rigid, dichotomous thinking impedes critical thinking in that it oversimplifies the complexity of social life in a pluralistic society (Bensley, 2023; Cheung et al., 2002; Halpern & Dunn, 2021) and tries to reduce complicated phenomena and resolve complex problems via “either/or” formulations and simplistic solutions.

In other words, folks with low critical thinking dispositions would tend to “keep it simple” when something is really quite complicated, and think it absolute terms and categories rather than seeing “the gray” in between the black and white extremes.

In sum, critical thinking dispositions are vitally important because they may help individuals avoid oversimplifying reality; they also permit perspective-taking and can facilitate their awareness of diversity and systematic biases, such as racial or gender bias. Some research has indicated that critical thinking dispositions uniquely contribute to academic performance beyond general cognition (Ren et al., 2020), and may help to reduce unsubstantiated claims and conspiracy beliefs (Bensley, 2023; Lantian et al., 2021).

But before we can study the potential impact of critical thinking dispositions, it is necessary to have a reliable, valid, and hopefully brief measure for this construct. I will discuss the development and validation of a measure of critical thinking dispositions in another post.
