Decision Theory and Rationality

Decision Theory and Rationality PDF Author: José Luis Bermúdez
Publisher: OUP Oxford
ISBN: 0191567728
Category : Philosophy
Languages : en
Pages : 199

Book Description
The concept of rationality is a common thread through the human and social sciences — from political science to philosophy, from economics to sociology, and from management science to decision analysis. But what counts as rational action and rational behavior? José Luis Bermúdez explores decision theory as a theory of rationality. Decision theory is the mathematical theory of choice and for many social scientists it makes the concept of rationality mathematically tractable and scientifically legitimate. Yet rationality is a concept with several dimensions and the theory of rationality has different roles to play. It plays an action-guiding role (prescribing what counts as a rational solution of a given decision problem). It plays a normative role (giving us the tools to pass judgment not just on how a decision problem was solved, but also on how it was set up in the first place). And it plays a predictive/explanatory role (telling us how rational agents will behave, or why they did what they did). This controversial but accessible book shows that decision theory cannot play all of these roles simultaneously. And yet, it argues, no theory of rationality can play one role without playing the other two. The conclusion is that there is no hope of taking decision theory as a theory of rationality.

Self-Control, Decision Theory, and Rationality

Self-Control, Decision Theory, and Rationality PDF Author: José Luis Bermúdez
Publisher: Cambridge University Press
ISBN: 1108349676
Category : Science
Languages : en
Pages : 521

Book Description
Thinking about self-control takes us to the heart of practical decision-making, human agency, motivation, and rational choice. Psychologists, philosophers, and decision theorists have all brought valuable insights and perspectives on how to model self-control, on different mechanisms for achieving and strengthening self-control, and on how self-control fits into the overall cognitive and affective economy. Yet these different literatures have remained relatively insulated from each other. Self-Control, Decision Theory, and Rationality brings them into dialog by focusing on the theme of rationality. It contains eleven newly written essays by a distinguished group of philosophers, psychologists, and decision theorists, together with a substantial introduction, collectively offering state-of-the-art perspectives on the rationality of self-control and the different mechanisms for achieving it.

Rational Decisions

Rational Decisions PDF Author: Ken Binmore
Publisher: Princeton University Press
ISBN: 1400833094
Category : Mathematics
Languages : en
Pages : 216

Book Description
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.

Rational Decisions in Organisations

Rational Decisions in Organisations PDF Author: Frédéric Adam
Publisher: CRC Press
ISBN: 1000543102
Category : Business & Economics
Languages : en
Pages : 245

Book Description
Managers in organisations must make rational decisions. Rational decision making is the opposite of intuitive decision making. It is a strict procedure utilising objective knowledge and logic. It involves identifying the problem to solve, gathering facts, identifying options and outcomes, analysing them, considering all the relationships and selecting the decision. Rational decision making requires support: methods and software tools. The identification of the problem to solve needs methods that would measure and evaluate the current situation. Identification and evaluation of options and analysis of the available possibilities involves analysis and optimisation methods. Incorporating intuition into rational decision making needs adequate methods that would translate ideas or observed behaviours into hard data. Communication, observation and opinions recording is hardly possible today without adequate software. Information and data that form the input, intermediate variables and the output must be stored, managed and made accessible in a user-friendly manner. Rational Decisions in Organisations: Theoretical and Practical Aspects presents selected recent developments in the support of the widely understood rational decision making in organisations, illustrated through case studies. The book shows not only the variety of perspectives involved in decision making, but also the variety of domains where rational decision support systems are needed. The case studies present decision making by medical doctors, students and managers of various universities, IT project teams, construction companies, banks and small and large manufacturing companies. Covering the richness of relationships in which the decisions should and must be taken, the book illustrates how modern organisations operate in chains and networks; they have multiple responsibilities, including social, legal, business and ethical duties. Nowadays, managers in organisations can make transparent decisions and consider a multitude of stakeholders and their diverse features, incorporating diverse criteria, using multiple types and drivers of information and decision-making patterns, and referring to numerous lessons learned. As the book makes clear, the marriage of theoretical ideas with the possibilities offered by technology can make the decisions in organisations more rational and, at the same time, more human.

Rational Choice in an Uncertain World

Rational Choice in an Uncertain World PDF Author: Reid Hastie
Publisher: SAGE
ISBN: 1412959039
Category : Psychology
Languages : en
Pages : 393

Book Description
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.

The Limits of Rationality

The Limits of Rationality PDF Author: Karen Schweers Cook
Publisher: University of Chicago Press
ISBN: 0226742415
Category : Political Science
Languages : en
Pages : 436

Book Description
Prevailing economic theory presumes that agents act rationally when they make decisions, striving to maximize the efficient use of their resources. Psychology has repeatedly challenged the rational choice paradigm with persuasive evidence that people do not always make the optimal choice. Yet the paradigm has proven so successful a predictor that its use continues to flourish, fueled by debate across the social sciences over why it works so well. Intended to introduce novices to rational choice theory, this accessible, interdisciplinary book collects writings by leading researchers. The Limits of Rationality illuminates the rational choice paradigm of social and political behavior itself, identifies its limitations, clarifies the nature of current controversies, and offers suggestions for improving current models. In the first section of the book, contributors consider the theoretical foundations of rational choice. Models of rational choice play an important role in providing a standard of human action and the bases for constitutional design, but do they also succeed as explanatory models of behavior? Do empirical failures of these explanatory models constitute a telling condemnation of rational choice theory or do they open new avenues of investigation and theorizing? Emphasizing analyses of norms and institutions, the second and third sections of the book investigate areas in which rational choice theory might be extended in order to provide better models. The contributors evaluate the adequacy of analyses based on neoclassical economics, the potential contributions of game theory and cognitive science, and the consequences for the basic framework when unequal bargaining power and hierarchy are introduced.

Risk and Rationality

Risk and Rationality PDF Author: Lara Buchak
Publisher: Oxford University Press
ISBN: 0199672164
Category : Mathematics
Languages : en
Pages : 273

Book Description
Lara Buchak sets out a new account of rational decision-making in the face of risk. She argues that the orthodox view (expected utility theory) is too narrow, and suggests an alternative, more permissive theory: one that allows individuals to pay attention to the worst-case or best-case scenario, and vindicates the ordinary decision-maker.
