Bishop and Trout here present a unique and provocative new approach to epistemology. Their approach aims to liberate epistemology from the scholastic debates of standard analytic epistemology, and treat it as a branch of the philosophy of science. The approach is novel in its use of cost-benefit analysis to guide people facing real reasoning problems and in its framework for resolving normative disputes in psychology. Based on empirical data, Bishop and Trout show how people can improve their reasoning by relying (...) on Statistical Prediction Rules. They then develop and articulate the positive core of the book. Their view, Strategic Reliabilism, claims that epistemic excellence consists in the efficient allocation of cognitive resources to reliable reasoning strategies, applied to significant problems. The last third of the book develops the implications of this view for standard analytic epistemology; for resolving normative disputes in psychology; and for offering practical, concrete advice on how this theory can improve real people's reasoning. This is a truly distinctive and controversial work that spans many disciplines and will speak to an unusually diverse group, including people in epistemology, philosophy of science, decision theory, cognitive and clinical psychology, and ethics and public policy.

Much research in the last two decades has demonstrated that human responses deviate from the performance deemed normative according to various models of decision making and rational judgment (e.g., the basic axioms of utility theory). This gap between the normative and the descriptive can be interpreted as indicating systematic irrationalities in human cognition. However, four alternative interpretations preserve the assumption that human behavior and cognition is largely rational. These posit that the gap is due to (1) performance errors, (2) computational (...) limitations, (3) the wrong norm being applied by the experimenter, and (4) a different construal of the task by the subject. In the debates about the viability of these alternative explanations, attention has been focused too narrowly on the modal response. In a series of experiments involving most of the classic tasks in the heuristics and biases literature, we have examined the implications of individual differences in performance for each of the four explanations of the normative/descriptive gap. Performance errors are a minor factor in the gap; computational limitations underlie non-normative responding on several tasks, particularly those that involve some type of cognitive decontextualization. Unexpected patterns of covariance can suggest when the wrong norm is being applied to a task or when an alternative construal of the task should be considered appropriate. Key Words: biases; descriptive models; heuristics; individual differences; normative models; rationality; reasoning. (shrink)

This paper reviews the largely psychological literature surrounding apparent failures of human rationality (sometimes referred to as 'the Rationality Wars') and locates it with respect to concepts and issues within more traditional epistemological inquiry. The goal is to bridge the gap between these two large and typically disconnected literatures – concerning rationality and the psychology of human reasoning, on the one hand, and epistemological theories of justified or rational belief, on the other – and to do so in such as (...) way as to expose interesting points of contact and convergence between them.

From Descartes to Popper, philosophers have criticized and tried to improve the strategies of reasoning invoked in science and in everyday life. In recent years leading cognitive psychologists have painted a detailed, controversial, and highly critical portrait of common sense reasoning. Stephen Stich begins with a spirited defense of this work and a critique of those writers who argue that widespread irrationality is a biological or conceptual impossibility.Stich then explores the nature of rationality and irrationality: What is it that distinguishes (...) good reasoning from bad? He rejects the most widely accepted approaches to this question approaches which unpack rationality by appeal to truth, to reflective equilibrium or conceptual analysis. The alternative he defends grows out of the pragmatic tradition in which reasoning is viewed as a cognitive tool. Stich's version of pragmatism leads to a radical epistemic relativism and he argues that the widespread abhorrence of relativism is ill founded. (shrink)

“Critical thinking in higher education” is a phrase that means many things to many people. It is a broad church. Does it mean a propensity for finding fault? Does it refer to an analytical method? Does it mean an ethical attitude or a disposition? Does it mean all of the above? Educating to develop critical intellectuals and the Marxist concept of critical consciousness are very different from the logician’s toolkit of finding fallacies in passages of text, or the practice of (...) identifying and distinguishing valid from invalid syllogisms. Critical thinking in higher education can also encompass debates about critical pedagogy, i.e., political critiques of the role and function of education in society, critical feminist approaches to curriculum, issues related to what has become known as critical citizenship, or any other education-related topic that uses the appellation “critical”. Equally, it can, and usually does, refer to the importance and centrality of developing general skills in reasoning—skills that we hope all graduates possess. Yet, despite more than four decades of dedicated scholarly work “critical thinking” remains as elusive as ever. As a concept, it is, as Raymond Williams has noted, a ‘most difficult one’ (Williams, 1976, p. 74). (shrink)

In this article I argue that most biases in argumentation and decision-making can and should be counteracted. Although biases can prove beneficial in certain contexts, I contend that they are generally maladaptive and need correction. Yet critical thinking alone seems insufficient to mitigate biases in everyday contexts. I develop a contextualist approach, according to which cognitive debiasing strategies need to be supplemented by extra-psychic devices that rely on social and environmental constraints in order to promote rational reasoning. Finally, I examine (...) several examples of contextual debiasing strategies and show how they can contribute to enhance critical thinking at a cognitive level. (shrink)

This is the full version of the Delphi Report on critical thinking and critical thinking instruction at the post-secondary level.

This article described three heuristics that are employed in making judgements under uncertainty: representativeness, which is usually employed when people are asked to judge the probability that an object or event A belongs to class or process B; availability of instances or scenarios, which is often employed when people are asked to assess the frequency of a class or the plausibility of a particular development; and adjustment from an anchor, which is usually employed in numerical prediction when a relevant value (...) is available. These heuristics are highly economical and usually effective, but they lead to systematic and predictable errors. A better understanding of these heuristics and of the biases to which they lead could improve judgements and decisions in situations of uncertainty. (shrink)

This title, first published in 1973, brings together a variety of papers by Israel Scheffler, one of America’s leading educational philosophers. The essays each stress the importance of critical thought and independent judgement to the organization of educational activities. In the first section, Scheffler adopts a metaphilosophical approach, emphasizing the role of philosophy in educational thought. A number of key concepts are dealt with next, including the study of education and its relation to theoretical disciplines, philosophical interpretations of teaching, and (...) the education of teachers. The final section is critical, and deals with the writings of several key thinkers in the field. A broad and authoritative study, this reissue will provide any Philosophy student with an essential background to the criticism and theories surrounding the philosophy of education. (shrink)

This paper focuses on the effects of motivational biases on the way people reason and debate in everyday life. Unlike heuristics and cognitive biases, motivational biases are typically caused by the influence of a desire or an emotion on the cognitive processes involved in judgmental and inferential reasoning. In line with the ‘motivational’ account of irrationality, I argue that these biases are the cause of a number of fallacies that ordinary arguers commit unintentionally, particularly when the commitment to a given (...) viewpoint is very strong. Drawing on recent work in argumentation theory and psychology, I show that there are privileged links between specific types of biases and specific types of fallacies. This analysis provides further support to the idea that people’s tendency to arrive at desired conclusions hinges on their ability to construct plausible justifications for those conclusions. I suggest that this effort to rationalize biased views is the reason why unintentional fallacies tend to be persuasive. (shrink)

Beginning with a discussion of the Informal Logic Movement and the renewed interest in critical thinking in education, this book critically assesses the work of Robert Ennis, Richard Paul and John McPeck.

This is the first of two companion articles drawn from a larger project, provisionally entitled Undisciplining Moral Epistemology. The overall goal is to understand how moral claims may be rationally justified in a world characterized by cultural diversity and social inequality. To show why a new approach to moral justification is needed, it is argued that several currently influential philosophical accounts of moral justification lend themselves to rationalizing the moral claims of those with more social power. The present article explains (...) how discourse ethics is flawed just in this way. The article begins by identifying several conditions of adequacy for assessing reasoning practices designed to achieve moral justification and shows that, when used in contexts of cultural diversity and social inequality, discourse ethics fails these conditions. It goes on to argue that the failure of discourse ethics is rooted in its reliance on a broader conception of moral epistemology that is invidiously idealized. It concludes by pointing to the need to rethink both the mission and the method of moral epistemology. (shrink)

This article challenges the common view that improvements in critical thinking are best pursued by investigations in informal logic. From the perspective of research in psychology and neuroscience, hu-man inference is a process that is multimodal, parallel, and often emo-tional, which makes it unlike the linguistic, serial, and narrowly cog-nitive structure of arguments. At-tempts to improve inferential prac-tice need to consider psychological error tendencies, which are patterns of thinking that are natural for peo-ple but frequently lead to mistakes in judgment. (...) This article discusses two important but neglected error ten-dencies: motivated inference and fear-driven inference. (shrink)

Is our case strong enough to go to trial? Will interest rates go up? Can I trust this person? Such questions - and the judgments required to answer them - are woven into the fabric of everyday experience. This book, first published in 2002, examines how people make such judgments. The study of human judgment was transformed in the 1970s, when Kahneman and Tversky introduced their 'heuristics and biases' approach and challenged the dominance of strictly rational models. Their work highlighted (...) the reflexive mental operations used to make complex problems manageable and illuminated how the same processes can lead to both accurate and dangerously flawed judgments. The heuristics and biases framework generated a torrent of influential research in psychology - research that reverberated widely and affected scholarship in economics, law, medicine, management, and political science. This book compiles the most influential research in the heuristics and biases tradition since the initial collection of 1982. (shrink)

In Educating Reason, Harvey Siegel presented the case regarding rationality and critical thinking as fundamental education ideals. In Rationality Redeemed? , a collection of essays written since that time, he develops this view, responds to major criticisms raised against it, and engages those critics in dialogue. In developing his ideas and responding to critics, Siegel addresses main currents in contemporary thought, including feminism, postmodernism and multiculturalism.

New Work on Critical Thinking: Comments on Frímannsson, Holma and Ritola.

In this article, I will introduce and explore the critical spirit component of critical thinking and defend it as significant for the adequate conceptualization of critical thinking as an educational aim. The idea of critical spirit has been defended among others by such eminent supporters of critical thinking as John Dewey, Israel Scheffler, and Harvey Siegel but has not thus far been explored and analyzed sufficiently. I will argue that the critical spirit has, in addition to cognitive, also moral and (...) emotional dimensions. Finally, I will touch upon some critiques which see that critical thinking either does not or ought not to involve moral or emotional dimensions. (shrink)

Critical thinking skills have associated critical thinking virtues, and the internal motivation to carefully examine an issue in an effort to reach a reasoned judgment, what I call the “willingness to inquire”, is the critical thinking virtue that stands behind all skilled and virtuous thinking that contributes to critical thinking. In this paper, I argue that the willingness to inquire is therefore a more primary critical thinking virtue than charity, open-mindedness, or valuing fallacious-free reasoning.

In this essay, I first discuss the conditions set by theorists of democratic deliberation on proper deliberation. These conditions call for reasoned decisions from mutually acceptable premises. Next, I present the ideal of critical thinking that should guide the citizen in this deliberation. I then examine the empirical literature on human reasoning. Some research results in the empirical literature paint a bleak picture of human rationality: we fall victim to heuristics and biases, persevere in our beliefs in the face of (...) contrary evidence, and justify our moral judgments by post hoc-reasoning. In addition, the deliberating groups have problems of their own. The groups may, for example, amplify errors or fall victim to information cascades. Though these epistemically detrimental processes can be overcome, they do present a challenge to our rationality. The essay concludes by arguing that the empirical evidence in fact supports an internalistic approach to group deliberation, a claim challenged by Solomon. (shrink)

Education's Epistemology extends and defends Siegel's "reasons conception" of critical thinking, developing it in both philosophical and educational directions. Of particular note is its emphasis on epistemic quality and epistemic rationality and its concerted defense of "universal" educational and philosophical ideals in the face of multicultural, postmodern, and other challenges.
