This book was released on 2021-02-25 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: An agent often does not have precise probabilities or utilities to guide resolution of a decision problem. I advance a principle of rationality for making decisions in such cases. To begin, I represent the doxastic and conative state of an agent with a set of pairs of a probability assignment and a utility assignment. Then I support a decision principle that allows any act that maximizes expected utility according to some pair of assignments in the set. Assuming that computation of an option's expected utility uses comprehensive possible outcomes that include the option's risk, no consideration supports a stricter requirement.
Book Synopsis Decision, Probability, and Utility by : Peter Gärdenfors
Download or read book Decision, Probability, and Utility written by Peter Gärdenfors and published by . This book was released on 1988 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decision theory and the theory of rational choice have recently been the subjects of considerable research by philosophers and economists. However, no adequate anthology exists which can be used to introduce students to the field. This volume is designed to meet that need. The essays included are organized into five parts covering the foundations of decision theory, the conceptualization of probability and utility, pholosophical difficulties with the rules of rationality and with the assessment of probability, and causal decision theory. The editors provide an extensive introduction to the field and introductions to each part.
Book Synopsis Commitment and Resoluteness in Rational Choice by : Chrisoula Andreou
Download or read book Commitment and Resoluteness in Rational Choice written by Chrisoula Andreou and published by Cambridge University Press. This book was released on 2022-03-03 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing and building on the existing literature, this Element explores the interesting and challenging philosophical terrain where issues regarding cooperation, commitment, and control intersect. Section 1 discusses interpersonal and intrapersonal Prisoner's Dilemma situations, and the possibility of a set of unrestrained choices adding up in a way that is problematic relative to the concerns of the choosers involved. Section 2 focuses on the role of precommitment devices in rational choice. Section 3 considers the role of resoluteness in rational choice and action. And Section 4 delves into some related complications concerning the nature of actions and the nature of intentions.
Book Synopsis Taking Chances by : Jordan Howard Sobel
Download or read book Taking Chances written by Jordan Howard Sobel and published by Cambridge University Press. This book was released on 1994-04-29 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: J. Howard Sobel has long been recognized as an important figure in philosophical discussions of rational decision. He has done much to help formulate the concept of causal decision theory. In this volume of essays Sobel explores the Bayesian idea that rational actions maximize expected values, where an action's expected value is a weighted average of its agent's values for its possible total outcomes. Newcomb's Problem and The Prisoner's Dilemma are discussed, and Allais-type puzzles are viewed from the perspective of causal world Bayesianism. The author establishes principles for distinguishing options in decision problems, and studies ways in which perfectly rational causal maximizers can be capable of resolute choices. Sobel also views critically Gauthier's revisionist ideas about maximizing rationality. This collection will be a desideratum for anyone working in the field of rational choice theory, whether in philosophy, economics, political science, psychology or statistics. Howard Sobel's work in decision theory is certainly among the most important, interesting and challenging that is being done by philosophers.
Book Synopsis The Measurement of Subjective Probability by : Edward J. R. Elliott
Download or read book The Measurement of Subjective Probability written by Edward J. R. Elliott and published by Cambridge University Press. This book was released on 2024-05-02 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beliefs come in degrees, and we often represent those degrees with numbers. We might say, for example, that we are 90% confident in the truth of some scientific hypothesis, or only 30% confident in the success of some risky endeavour. But what do these numbers mean? What, in other words, is the underlying psychological reality to which the numbers correspond? And what constitutes a meaningful difference between numerically distinct representations of belief? In this Element, we discuss the main approaches to the measurement of belief. These fall into two broad categories-epistemic and decision-theoretic-with divergent foundations in the theory of measurement. Epistemic approaches explain the measurement of belief by appeal to relations between belief states themselves, whereas decision-theoretic approaches appeal to relations between beliefs and desires in the production of choice and preferences.
Book Synopsis Realistic Decision Theory by : Paul Weirich
Download or read book Realistic Decision Theory written by Paul Weirich and published by Oxford University Press. This book was released on 2004-09-16 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within traditional decision theory, common decision principles -- e.g. the principle to maximize utility -- generally invoke idealization; they govern ideal agents in ideal circumstances. In Realistic Decision Theory, Paul Weirch adds practicality to decision theory by formulating principles applying to nonideal agents in nonideal circumstances, such as real people coping with complex decisions. Bridging the gap between normative demands and psychological resources, Realistic Decision Theory is essential reading for theorists seeking precise normative decision principles that acknowledge the limits and difficulties of human decision-making.
Book Synopsis Phylogenetic Trees and Molecular Evolution by : David R. Bickel
Download or read book Phylogenetic Trees and Molecular Evolution written by David R. Bickel and published by Springer Nature. This book was released on 2022-09-29 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book serves as a brief introduction to phylogenetic trees and molecular evolution for biologists and biology students. It does so by presenting the main concepts in a variety of ways: first visually, then in a history, next in a dice game, and finally in simple equations. The content is primarily designed to introduce upper-level undergraduate and graduate students of biology to phylogenetic tree reconstruction and the underlying models of molecular evolution. A unique feature also of interest to experienced researchers is the emphasis on simple ways to quantify the uncertainty in the results more fully than is possible with standard methods.
Book Synopsis Preference Change by : David Strohmaier
Download or read book Preference Change written by David Strohmaier and published by Cambridge University Press. This book was released on 2024-01-31 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: For most of its history, decision theory has investigated the rational choices of humans under the assumption of static preferences. Human preferences, however, change. In recent years, decision theory has increasingly acknowledged the reality of preference change throughout life. This Element provides an accessible introduction and new contributions to the debates on preference change. It is divided into three chapters. In the first chapter, the authors discuss what preference change is and whether we can integrate it into decision theory. In the second chapter, they present models of preference change, including a novel proposal of their own. In the third and final chapter, they discuss how we can rationally choose a course of action when our preferences might change. Both the transformative experience literature and recent work on choosing for changing selves are discussed.
Book Synopsis Rational Responses to Risks by : Paul Weirich
Download or read book Rational Responses to Risks written by Paul Weirich and published by Oxford University Press. This book was released on 2020-07-10 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Good decisions account for risks. For example, the risk of an accident while driving in the rain makes a reasonable driver decide to slow down. While risk is a large topic in theoretical disciplines such as economics and psychology, as well as in practical disciplines such as medicine and finance, philosophy has a unique contribution to make in developing a normative theory of risk that states what risk is, and to what extent our responses to it are rational. Weirich here develops a philosophical theory of the rationality of responses to risk. He first distinguishes two types of risk: first, a chance of a bad event, and second, an act's risk in relation to its possible outcomes. He argues that this distinction has normative significance in the sense that one's attitudes towards these types of risks - and how one acts on them - are governed by different general principles of rationality. Consequently, a comprehensive account of risk must not only characterize rational responses to risk but also explain why these responses are rational. Weirich explains how, for a rational ideal agent, the expected utilities of the acts available in a decision problem explain the agent's preferences among the acts. As a result, maximizing expected utility is just following preferences among the acts. His view takes an act's expected utility, not just as a feature of a representation of preferences among acts, but also as a factor in the explanation of preferences among acts. The book's precise formulation of general standards of rationality for attitudes and for acts, and its rigorous argumentation for these standards, make it philosophical; but while mainly of interest to philosophers, its broader arguments will contribute to the conceptual foundations of studies of risk in all disciplines that study it.
Book Synopsis Money-Pump Arguments by : Johan E. Gustafsson
Download or read book Money-Pump Arguments written by Johan E. Gustafsson and published by Cambridge University Press. This book was released on 2022-10-13 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Suppose that you prefer A to B, B to C, and C to A. Your preferences violate Expected Utility Theory by being cyclic. Money-pump arguments offer a way to show that such violations are irrational. Suppose that you start with A. Then you should be willing to trade A for C and then C for B. But then, once you have B, you are offered a trade back to A for a small cost. Since you prefer A to B, you pay the small sum to trade from B to A. But now you have been turned into a money pump. You are back to the alternative you started with but with less money. This Element shows how each of the axioms of Expected Utility Theory can be defended by money-pump arguments of this kind. This title is also available as Open Access on Cambridge Core.
Book Synopsis Political Party Financing and Electoral Politics in Nigeria’s Fourth Republic by : Babayo Sule
Download or read book Political Party Financing and Electoral Politics in Nigeria’s Fourth Republic written by Babayo Sule and published by Rowman & Littlefield. This book was released on 2023-03-17 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Political Party Financing and Electoral Politics in Nigeria’s Fourth Republic, Babayo Sule provides a detailed analysis of the process of political party financing in Nigeria from 1999 to the present. Sule links the party financing process with the electoral process and explores issues of democratic accountability, transparency, and corruption in Nigeria under democratic rule. Issues of excessive spending, violation of legal procedures for party financing and monitoring of parties’ activities, particularly, finances are explored. The book presents an analytical discourse on elections and processes that influence an election in Nigeria’s Fourth Republic in which party financing and money politics are instrumental. This book observes how political corruption gains root in the process of party financing and builds a theory linking party financing, electoral politics, and democratic accountability. This book provides practical policy implications for strengthening Nigeria’s electoral process and transparency in its democracy.
Book Synopsis A Plea for Plausibility by : John R. Welch
Download or read book A Plea for Plausibility written by John R. Welch and published by Taylor & Francis. This book was released on 2023-03-17 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book develops an original theory of decision-making based on the concept of plausibility. The author advocates plausible reasoning as a general philosophical method and demonstrates how it can be applied to problems in argumentation theory, scientific theory choice, risk management, ethics, law, economics, and epistemology. Human decisions are conditioned by formidable uncertainty. The standard resource for dealing rationally with uncertainty is the mathematical concept of probability. The probability calculus is well-known, but since the numerical demands for applying it cannot usually be met, it is not widely applicable. By contrast, the concept of plausibility is widely applicable, but it is little known. This book relies on a generalized concept of plausibility whose strength is its adaptability. The adaptability is due to a novel form of decision theory that takes plausibilities as inputs. This form of decision theory remains applicable to decisions informed by sharp probabilities and utilities, but it can also be applied to decisions that must be made without them. It can aid in the rationally critical enterprise of discriminating good arguments from bad, and this can foster philosophical progress. A Plea for Plausibility will be of interest to scholars and advanced students working in argumentation theory, philosophy of science, ethics, epistemology, economics, law, and risk management.

Book Synopsis The Foundations of Causal Decision Theory by : James M. Joyce
Download or read book The Foundations of Causal Decision Theory written by James M. Joyce and published by Cambridge University Press. This book was released on 1999-04-13 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book defends the view that any adequate account of rational decision making must take a decision maker's beliefs about causal relations into account. The early chapters of the book introduce the non-specialist to the rudiments of expected utility theory. The major technical advance offered by the book is a 'representation theorem' that shows that both causal decision theory and its main rival, Richard Jeffrey's logic of decision, are both instances of a more general conditional decision theory. The book solves a long-standing problem for Jeffrey's theory by showing for the first time how to obtain a unique utility and probability representation for preferences and judgements of comparative likelihood. The book also contains a major new discussion of what it means to suppose that some event occurs or that some proposition is true. The most complete and robust defence of causal decision theory available.
Book Synopsis Political Philosophy by : Mario Bunge
Download or read book Political Philosophy written by Mario Bunge and published by Routledge. This book was released on 2017-07-12 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Political philosophy is not a well-defined field. It hovers between political theory and classical philosophy. Few early political thinkers could have anticipated the most pressing political issues of our time: the need to stop global warming; the reduction of nuclear armaments; the rise of inequality between individuals and nations; and the struggle against authoritarianism, particularly when it comes disguised as democracy or as socialism. Here, celebrated philosopher Mario Bunge masterfully integrates socio-political theory into a philosophical exploration of power and resource distribution in the world today. Bunge contends that even recent political thinkers have generally failed to address the political underpinnings of topical issues. Environmental degradation, gender and race discriminations, participative democracy, nationalism, imperialism, the North-South divide, resource wars, and the industrial-military complex have all largely been bypassed in political thinking. Even connections between poverty and environmental degradation, and between inequality and bad health, have escaped the attention of those who would call themselves political thinkers. Bunge believes that political philosophers should pay more attention to social indicators, such as the standard index of income inequality and the United Nations human development index. It is pointless to write about redistributive policies unless we have a shared understanding of current wealth distribution. This is, in short, a modern treatise on sociopolitical concerns.
Book Synopsis Thinking about Acting by : John L. Pollock
Download or read book Thinking about Acting written by John L. Pollock and published by Oxford University Press. This book was released on 2006-07-27 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work aims to construct a theory of rational decision making for real, resource-bounded, agents. Such decision making must be based on objective probabilities rather than subjective probabilities, and can't be done by choosing single action with maxmimal expected values.
