How to assess critical aspects of cognitive functioning that are not measured by IQ tests: rational thinking skills. Why are we surprised when smart people act foolishly? Smart people do foolish things all the time. Misjudgments and bad decisions by highly educated bankers and money managers, for example, brought us the financial crisis of 2008. Smart people do foolish things because intelligence is not the same as the capacity for rational thinking. The Rationality Quotient explains that these two traits, often (and incorrectly) thought of as one, refer to different cognitive functions. The standard IQ test, the authors argue, doesn't measure any of the broad components of rationality—adaptive responding, good judgment, and good decision making. The authors show that rational thinking, like intelligence, is a measurable cognitive competence. Drawing on theoretical work and empirical research from the last two decades, they present the first prototype for an assessment of rational thinking analogous to the IQ test: the CART (Comprehensive Assessment of Rational Thinking). The authors describe the theoretical underpinnings of the CART, distinguishing the algorithmic mind from the reflective mind. They discuss the logic of the tasks used to measure cognitive biases, and they develop a unique typology of thinking errors. The Rationality Quotient explains the components of rational thought assessed by the CART, including probabilistic and scientific reasoning; the avoidance of “miserly” information processing; and the knowledge structures needed for rational thinking. Finally, the authors discuss studies of the CART and the social and practical implications of such a test. An appendix offers sample items from the test.

Critics of intelligence tests writers such as Robert Sternberg, Howard Gardner, and Daniel Goleman have argued in recent years that these tests neglect important qualities such as emotion, empathy, and interpersonal skills. However, such critiques imply that though intelligence tests may miss certain key noncognitive areas, they encompass most of what is important in the cognitive domain. In this book, Keith E. Stanovich challenges this widely held assumption.Stanovich shows that IQ tests (or their proxies, such as the SAT) are radically incomplete as measures of cognitive functioning. They fail to assess traits that most people associate with good thinking, skills such as judgment and decision making. Such cognitive skills are crucial to real-world behavior, affecting the way we plan, evaluate critical evidence, judge risks and probabilities, and make effective decisions. IQ tests fail to assess these skills of rational thought, even though they are measurable cognitive processes. Rational thought is just as important as intelligence, Stanovich argues, and it should be valued as highly as the abilities currently measured on intelligence tests.

This book develops the idea of rational expectations and surveys its use in economics today.

NEW YORK TIMES BESTSELLER “In our uncertain age, which can so often feel so dark and disturbing, Steven Pinker has distinguished himself as a voice of positivity.” – New York Times Can reading a book make you more rational? Can it help us understand why there is so much irrationality in the world? Steven Pinker, author of Enlightenment Now (Bill Gates’s "new favorite book of all time”) answers all the questions here Today humanity is reaching new heights of scientific understanding--and also appears to be losing its mind. How can a species that developed vaccines for Covid-19 in less than a year produce so much fake news, medical quackery, and conspiracy theorizing? Pinker rejects the cynical cliché that humans are simply irrational--cavemen out of time saddled with biases, fallacies, and illusions. After all, we discovered the laws of nature, lengthened and enriched our lives, and set out the benchmarks for rationality itself. We actually think in ways that are sensible in the low-tech contexts in which we spend most of our lives, but fail to take advantage of the powerful tools of reasoning we’ve discovered over the millennia: logic, critical thinking, probability, correlation and causation, and optimal ways to update beliefs and commit to choices individually and with others. These tools are not a standard part of our education, and have never been presented clearly and entertainingly in a single book--until now. Rationality also explores its opposite: how the rational pursuit of self-interest, sectarian solidarity, and uplifting mythology can add up to crippling irrationality in a society. Collective rationality depends on norms that are explicitly designed to promote objectivity and truth. Rationality matters. It leads to better choices in our lives and in the public sphere, and is the ultimate driver of social justice and moral progress. Brimming with Pinker’s customary insight and humor, Rationality will enlighten, inspire, and empower.

The authors explain the underlying software development principles behind theRUP, and guide readers in its application in their organization.

This volume of articles (most published, some new) is a follow-up to the late Wesley C. Salmon's widely read collection Causality And Explanation (OUP 1998). It contains both published and unpublished articles, and focuses on two related areas of inquiry: First, is science a rational enterprise? Secondly, does science yield objective information about our world, even the aspects that we cannot observe directly? Salmon's own take is that objective knowledge of the world is possible, and his work in these articles centers around proving that this can be so. Salmon's influential standing in the field ensures that this volume will be of interest to both undergraduates and professional philosophers, primarily in the philosophy of science.

Rectifying misrepresentations of Popperian thought with a historical approach to Popper’s philosophy, Gattei reconstructs the logic of Popper’s development to show how one problem and its tentative solution led to a new problem.

In Decision Making and Rationality in the Modern World, Keith E. Stanovich demonstrates how work in the cognitive psychology of decision making has implications for the large and theoretically contentious debates about the nature of human rationality. Written specifically for undergraduate psychology students, the book presents a very practical approach to decision making, which is too often perceived by students as an artificial set of skills used only in academia and not in the real world. Instead, Stanovich shows how good decision-making procedures support rational behavior that enables people to act most efficiently to fulfill their goals. He explains how the concept of rationality is understood in cognitive science in terms of good decision making and judgment. Books in the Fundamentals of Cognition series serve as ideal instructional resources for advanced courses in cognitive psychology. They provide an up-to-date, well-organized survey of our current understanding of the major theories of cognitive psychology. The books are concise, which allows instructors to incorporate the latest original research and readings into their courses without overburdening their students. Focused without being too advanced--and comprehensive without being too broad--these books are the perfect resource for both students and instructors.

Mainstream economists everywhere exhibit an "irrational passion for dispassionate rationality." Behavioral economists, and long-time critic of mainstream economics suggests that people in mainstrean economic models "can think like Albert Einstein, store as much memory as IBM’s Big Blue, and exercise the will power of Mahatma Gandhi," suggesting that such a view of real world modern homo sapiens is simply wrongheaded. Indeed, Thaler and other behavioral economists and psychology have documented a variety of ways in which real-world people fall far short of mainstream economists' idealized economic actor, perfectly rational homo economicus. Behavioral economist Daniel Ariely has concluded that real-world people not only exhibit an array of decision-making frailties and biases, they are "predictably irrational," a position now shared by so many behavioral economists, psychologists, sociologists, and evolutionary biologists that a defense of the core rationality premise of modedrn economics is demanded.
