Download or read book Rational Decisions written by Ken Binmore and published by Princeton University Press. This book was released on 2008-12-29 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is widely held that Bayesian decision theory is the final word on how a rational person should make decisions. However, Leonard Savage--the inventor of Bayesian decision theory--argued that it would be ridiculous to use his theory outside the kind of small world in which it is always possible to "look before you leap." If taken seriously, this view makes Bayesian decision theory inappropriate for the large worlds of scientific discovery and macroeconomic enterprise. When is it correct to use Bayesian decision theory--and when does it need to be modified? Using a minimum of mathematics, Rational Decisions clearly explains the foundations of Bayesian decision theory and shows why Savage restricted the theory's application to small worlds. The book is a wide-ranging exploration of standard theories of choice and belief under risk and uncertainty. Ken Binmore discusses the various philosophical attitudes related to the nature of probability and offers resolutions to paradoxes believed to hinder further progress. In arguing that the Bayesian approach to knowledge is inadequate in a large world, Binmore proposes an extension to Bayesian decision theory--allowing the idea of a mixed strategy in game theory to be expanded to a larger set of what Binmore refers to as "muddled" strategies. Written by one of the world's leading game theorists, Rational Decisions is the touchstone for anyone needing a concise, accessible, and expert view on Bayesian decision making.

Book excerpt: Taking Savage's (1954) subjective expected utility theory as a starting point, this thesis distinguishes three types of uncertainty which are incompatible with Savage's theory for small worlds: ambiguity, option uncertainty and state space uncertainty. Under ambiguity agents cannot form a unique and additive probability function over the state space. Option uncertainty exists when agents cannot assign unique consequences to every state. Finally, state space uncertainty arises when the state space the agent constructs is not exhaustive, such that unforeseen contingencies can occur. Chapter 2 explains Savage's notions of small and large worlds, and shows that ambiguity, option and state space uncertainty are incompatible with the small world representation. The chapter examines whether it is possible to reduce these types of uncertainty to one another. Chapter 3 suggests a definition of objective ambiguity by extending Savage's framework to include an exogenous likelihood ranking over events. The definition allows for a precise distinction between ambiguity and ambiguity attitude. The chapter argues that under objective ambiguity, ambiguity aversion is normatively permissible. Chapter 4 gives a model of option uncertainty. Using the two weak assumptions that the status quo is not uncertain, and that agents are option uncertainty averse, we derive status quo bias, the empirical tendency for agents to choose the status quo over other available alternatives. The model can be seen as rationalising status quo bias. Chapter 5 gives an axiomatic characterisation and corresponding representation theorem for the priority heuristic, a heuristic which predicts binary decisions be- tween lotteries particularly well. The chapter analyses the normative implications of this descriptive model. Chapter 6 defends the pluralist view of decision theory this thesis assumes. The chapter discusses possible applications of the types of uncertainty defined in the thesis, and concludes.

Download or read book Decision Making and Rationality in the Modern World written by Keith E. Stanovich and published by Oxford University Press, USA. This book was released on 2010 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Rational Choice in an Uncertain World written by Reid Hastie and published by SAGE. This book was released on 2010 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Second Edition of Rational Choice in an Uncertain World the authors compare the basic principles of rationality with actual behaviour in making decisions. They describe theories and research findings from the field of judgment and decision making in a non-technical manner, using anecdotes as a teaching device. Intended as an introductory textbook for advanced undergraduate and graduate students, the material not only is of scholarly interest but is practical as well. The Second Edition includes: - more coverage on the role of emotions, happiness, and general well-being in decisions - a summary of the new research on the neuroscience of decision processes - more discussion of the adaptive value of (non-rational heuristics) - expansion of the graphics for decision trees, probability trees, and Venn diagrams.
Download or read book Evolution and Rationality written by Samir Okasha and published by Cambridge University Press. This book was released on 2012-06-21 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores from multiple perspectives the subtle and interesting relationship between the theory of rational choice and Darwinian evolution. In rational choice theory, agents are assumed to make choices that maximize their utility; in evolution, natural selection 'chooses' between phenotypes according to the criterion of fitness maximization. So there is a parallel between utility in rational choice theory and fitness in Darwinian theory. This conceptual link between fitness and utility is mirrored by the interesting parallels between formal models of evolution and rational choice. The essays in this volume, by leading philosophers, economists, biologists and psychologists, explore the connection between evolution and rational choice in a number of different contexts, including choice under uncertainty, strategic decision making and pro-social behaviour. They will be of interest to students and researchers in philosophy of science, evolutionary biology, economics and psychology.

Book excerpt: To a historian the most interesting thing about decisions is the fact that everyone talks about them. No one interested in social ideas can fail to notice how large a part the word "decision" has come to play in the vocabulary of moral and political discourse. It meets one on every page. Inevitably one asks, "Why?" Why is there so much talk of decisions and of those who are said to make them? Are there any ideological reasons for it?

Download or read book Bounded Rationality written by Gerd Gigerenzer and published by MIT Press. This book was released on 2002-07-26 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a complex and uncertain world, humans and animals make decisions under the constraints of limited knowledge, resources, and time. Yet models of rational decision making in economics, cognitive science, biology, and other fields largely ignore these real constraints and instead assume agents with perfect information and unlimited time. About forty years ago, Herbert Simon challenged this view with his notion of "bounded rationality." Today, bounded rationality has become a fashionable term used for disparate views of reasoning. This book promotes bounded rationality as the key to understanding how real people make decisions. Using the concept of an "adaptive toolbox," a repertoire of fast and frugal rules for decision making under uncertainty, it attempts to impose more order and coherence on the idea of bounded rationality. The contributors view bounded rationality neither as optimization under constraints nor as the study of people's reasoning fallacies. The strategies in the adaptive toolbox dispense with optimization and, for the most part, with calculations of probabilities and utilities. The book extends the concept of bounded rationality from cognitive tools to emotions; it analyzes social norms, imitation, and other cultural tools as rational strategies; and it shows how smart heuristics can exploit the structure of environments.

Book excerpt: A TIMES BOOK OF THE YEAR 2021 'Punchy, funny and invigorating ... Pinker is the high priest of rationalism' Sunday Times 'If you've ever considered taking drugs to make yourself smarter, read Rationality instead. It's cheaper, more entertaining, and more effective' Jonathan Haidt, author of The Righteous Mind In the twenty-first century, humanity is reaching new heights of scientific understanding - and at the same time appears to be losing its mind. How can a species that discovered vaccines for Covid-19 in less than a year produce so much fake news, quack cures and conspiracy theorizing? In Rationality, Pinker rejects the cynical cliché that humans are simply an irrational species - cavemen out of time fatally cursed with biases, fallacies and illusions. After all, we discovered the laws of nature, lengthened and enriched our lives and set the benchmarks for rationality itself. Instead, he explains, we think in ways that suit the low-tech contexts in which we spend most of our lives, but fail to take advantage of the powerful tools of reasoning we have built up over millennia: logic, critical thinking, probability, causal inference, and decision-making under uncertainty. These tools are not a standard part of our educational curricula, and have never been presented clearly and entertainingly in a single book - until now. 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 insight and humour, Rationality will enlighten, inspire and empower. 'A terrific book, much-needed for our time' Peter Singer
Download or read book Simply Rational written by Gerd Gigerenzer and published by Oxford University Press. This book was released on 2015-03-03 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Statistical illiteracy can have an enormously negative impact on decision making. This volume of collected papers brings together applied and theoretical research on risks and decision making across the fields of medicine, psychology, and economics. Collectively, the essays demonstrate why the frame in which statistics are communicated is essential for broader understanding and sound decision making, and that understanding risks and uncertainty has wide-reaching implications for daily life. Gerd Gigerenzer provides a lucid review and catalog of concrete instances of heuristics, or rules of thumb, that people and animals rely on to make decisions under uncertainty, explaining why these are very often more rational than probability models. After a critical look at behavioral theories that do not model actual psychological processes, the book concludes with a call for a "heuristic revolution" that will enable us to understand the ecological rationality of both statistics and heuristics, and bring a dose of sanity to the study of rationality.

Download or read book Normal Rationality written by Edna Ullmann-Margalit and published by Oxford University Press. This book was released on 2017-08-25 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Normal Rationality is a selection of the most important work of Edna Ullmann-Margalit, presenting some influential and widely admired essays alongside some that are not well known. She was an unorthodox and deeply original philosopher whose work illuminated the largest mysteries of human life. Much of her writing focuses on two fundamental questions. (1) How do people proceed when they cannot act on the basis of reasons, or project likely consequences? (2) How is social order possible? Ullmann-Margalit's answers, emphasizing what might be called biased rationality, are important not only for philosophy, but also for political science, psychology, sociology, cognitive science, economics (including behavioral economics), law, and even public policy. Ullmann-Margalit demonstrates that people have identifiable strategies for making difficult decisions, whether the question is small (what to buy at a supermarket) or big (whether to transform one's life in some large-scale way). She also shows that social dilemmas are solved by norms; that invisible-hand explanations take two identifiable (and dramatically different) forms; that trust can emerge in seemingly unpromising situations; and that considerateness is the foundation on which our relationships are organized in both the thin context of the public space and the intimate context of the family. One of the distinguishing features of Ullmann-Margalit's work is its close attention to the details of human experience, and its use of those details to offer fresh understandings of social phenomena. Her essays cast new light on a diverse assortment of problems in philosophy, social science, and individual lives.
Download or read book The Irrational Economist written by Erwann Michel-Kerjan and published by ReadHowYouWant.com. This book was released on 2010 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of the twenty most costly catastrophes since 1970, more than half have occurred since 2001. Is this an omen of what the 21st century will be? How might we behave in this new, uncertain and more dangerous environment? Will our actions be rational or irrational? A select group of scholars, innovators, and Nobel Laureates was asked to address challenges to rational decision making both in our day-to-day life and in the face of catastrophic threats such as climate changes, natural disasters, technological hazards, and human malevolence. At the crossroads of decision sciences, behavioral and neuro-economics, psychology, management, insurance, and finance, their contributions aim to introduce readers to the latest thinking and discoveries. The Irrational Economist challenges the conventional wisdom about how to make the right decisions in the new era we have entered. It reveals a profound revolution in thinking as understood by some of the greatest minds in our day, and underscores the growing role and impact of economists and other social scientists as they guide our most important personal and societal decisions.

Download or read book Bounded Rationality written by Sanjit Dhami and published by MIT Press. This book was released on 2022-07-12 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two leaders in the field explore the foundations of bounded rationality and its effects on choices by individuals, firms, and the government. Bounded rationality recognizes that human behavior departs from the perfect rationality assumed by neoclassical economics. In this book, Sanjit Dhami and Cass R. Sunstein explore the foundations of bounded rationality and consider the implications of this approach for public policy and law, in particular for questions about choice, welfare, and freedom. The authors, both recognized as experts in the field, cover a wide range of empirical findings and assess theoretical work that attempts to explain those findings. Their presentation is comprehensive, coherent, and lucid, with even the most technical material explained accessibly. They not only offer observations and commentary on the existing literature but also explore new insights, ideas, and connections. After examining the traditional neoclassical framework, which they refer to as the Bayesian rationality approach (BRA), and its empirical issues, Dhami and Sunstein offer a detailed account of bounded rationality and how it can be incorporated into the social and behavioral sciences. They also discuss a set of models of heuristics-based choice and the philosophical foundations of behavioral economics. Finally, they examine libertarian paternalism and its strategies of “nudges.”
