Considers that intuitive predictions follow a judgmental heuristic-representativeness. By this heuristic, people predict the outcome that appears most representative of the evidence. Consequently, intuitive predictions are insensitive to the reliability of the evidence or to the prior probability of the outcome, in violation of the logic of statistical prediction. The hypothesis that people predict by representativeness was supported in a series of studies with both naive and sophisticated university students. The ranking of outcomes by likelihood coincided with the ranking by (...) representativeness, and Ss erroneously predicted rare events and extreme values if these happened to be representative. The experience of unjustified confidence in predictions and the prevalence of fallacious intuitions concerning statistical regression are traced to the representativeness heuristic. (shrink)

Moral thinking pervades our practical lives, but where did this way of thinking come from, and what purpose does it serve? Is it to be explained by environmental pressures on our ancestors a million years ago, or is it a cultural invention of more recent origin? In The Evolution of Morality, Richard Joyce takes up these controversial questions, finding that the evidence supports an innate basis to human morality. As a moral philosopher, Joyce is interested in whether any implications follow (...) from this hypothesis. Might the fact that the human brain has been biologically prepared by natural selection to engage in moral judgment serve in some sense to vindicate this way of thinking--staving off the threat of moral skepticism, or even undergirding some version of moral realism? Or if morality has an adaptive explanation in genetic terms--if it is, as Joyce writes, "just something that helped our ancestors make more babies"--might such an explanation actually undermine morality's central role in our lives? He carefully examines both the evolutionary "vindication of morality" and the evolutionary "debunking of morality," considering the skeptical view more seriously than have others who have treated the subject.Interdisciplinary and combining the latest results from the empirical sciences with philosophical discussion, The Evolution of Morality is one of the few books in this area written from the perspective of moral philosophy. Concise and without technical jargon, the arguments are rigorous but accessible to readers from different academic backgrounds. Joyce discusses complex issues in plain language while advocating subtle and sometimes radical views. The Evolution of Morality lays the philosophical foundations for further research into the biological understanding of human morality. (shrink)

In public political deliberation, people will err and lie in accordance with definite patterns. Such discourse failure results from behavior that is both instrumentally and epistemically rational. The deliberative practices of a liberal democracy cannot be improved so as to overcome the tendency for rational citizens to believe and say things at odds with reliable propositions of social science. The theory has several corollaries. One is that much contemporary political philosophy can be seen as an unsuccessful attempt to vindicate, on (...) symbolic and moral grounds, the forms that discourse failure take on in public political deliberation. Another is that deliberative practices cannot be rescued even on non-epistemic grounds, such as social peace, impartiality, participation, and equality. To alleviate discourse failure, this book proposes to reduce the scope of majoritarian politics and enlarge markets. (shrink)

The Collected Works of John Stuart Mill was directed by an editorial committee appointed from the Faculty of Arts and Science of the University of Toronto and from the University of Toronto Press, and it was published from 1963 to 1991 in thirty-three hardcover volumes. The primary aim of the edition is to present fully collated, accurate texts of those works which exist in a number of versions, both printed and manuscript, and to provide accurate texts of those works previously (...) unpublished or which had become relatively inaccessible. Liberty Fund is pleased to make available in paperback eight volumes of Mill's writings that remain most relevant to liberty and responsibility in the twenty-first century. Mill's Autobiography gives a vivid account of his life, especially his unique education. The Principles of Political Economy, a compendium of economic theory and fact, was the leading economic textbook for decades. Primarily of interest to economists, his Essays on Economics and Society nevertheless contains material of interest to all students of the politics and society of nineteenth-century England. The most indispensable work in understanding his thought is A System of Logic, Ratiocinative and Inductive, which was the first serious attempt to methodize induction in relation to deduction. Essays on Ethics, Religion and Society, one of the most important volumes in the Collected Works, includes the major documents for an assessment of Mill's response to Benthamite utilitarianism and for understanding his development of an independent moral position.

Sentimental Rules is an ambitious and highly interdisciplinary work, which proposes and defends a new theory about the nature and evolution of moral judgment. In it, philosopher Shaun Nichols develops the theory that emotions play a critical role in both the psychological and the cultural underpinnings of basic moral judgment. Nichols argues that our norms prohibiting the harming of others are fundamentally associated with our emotional responses to those harms, and that such 'sentimental rules' enjoy an advantage in cultural evolution, (...) which partly explains the success of certain moral norms. This has sweeping and exciting implications for philosophical ethics. Nichols builds on an explosion of recent intriguing experimental work in psychology on our capacity for moral judgment and shows how this empirical work has broad import for enduring philosophical problems. The result is an account that illuminates fundamental questions about the character of moral emotions and the role of sentiment and reason in how we make our moral judgments. This work should appeal widely across philosophy and the other disciplines that comprise cognitive science. (shrink)

Summary of, and response to criticism of, the authors' book, Fairness versus welfare (Harvard University Press, 2002).

The defects of any form of government may be either negative or positive. It is negatively defective if it does not concentrate in the hands of the authorities power sufficient to fulfil the necessary offices of a government; or if it does not sufficiently develop by exercise the active capacities and social feelings of the individual citizens. On neither of these points is it necessary that much should be said at this stage of our inquiry.

A central theme in F. A. Hayek’s work is the contrast between principles and expediency, and the insistence that governments follow abstract general principles rather than pursue apparently expedient social and economic policies that seek to make us better off.2 This is a radical and striking thesis, especially from an economist: governments should abjure the pursuit of social and economic policies that aim to improve welfare and, instead, adhere to moral principles. In this chapter I defend this radical claim. I (...) begin by explicating and defending Hayek’s argument against the pursuit of expediency based on his analysis of economic and social complexity. I then turn to a rather more critical examination of his evolutionary account of moral principles. (shrink)

This paper generalises the classical Condorcet jury theorem from majority voting over two options to plurality voting over multiple options. The paper further discusses the debate between epistemic and procedural democracy and situates its formal results in that debate. The paper finally compares a number of different social choice procedures for many-option choices in terms of their epistemic merits. An appendix explores the implications of some of the present mathematical results for the question of how probable majority cycles (as in (...) Condorcet's paradox) are in large electorates.

Deontic reasoning is reasoning about permission and obligation: what one may do and what one must do, respectively. Conceivably, people could reason about deontic matters using a purely formal deontic calculus. I review evidence from a range of psychological experiments suggesting that this is not the case. Instead, I argue that deontic reasoning is supported by a collection of dissociable cognitive adaptations for solving adaptive problems that likely would have confronted ancestral humans.

The thirty-five chapters in this book describe various judgmental heuristics and the biases they produce, not only in laboratory experiments but in important...

Repeatedly and successfully, the celebrated Harvard philosopher Robert Nozick has reached out to a broad audience beyond the confines of his discipline, addressing ethical and social problems that matter to every thoughtful person. Here Nozick continues his search for the connections between philosophy and "ordinary" experience. In the lively and accessible style that his readers have come to expect, he offers a bold theory of rationality, the one characteristic deemed to fix humanity's "specialness." What are principles for? asks Nozick. We (...) could act simply on whim, or maximize our self-interest and recommend that others do the same. As Nozick explores rationality of decision and rationality of belief, he shows how principles actually function in our day-to-day thinking and in our efforts to live peacefully and productively with each other. Throughout, the book combines daring speculations with detailed investigations to portray the nature and status of rationality and the essential role that imagination plays in this singular human aptitude.

In The Grammar of Society, first published in 2006, Cristina Bicchieri examines social norms, such as fairness, cooperation, and reciprocity, in an effort to understand their nature and dynamics, the expectations that they generate, and how they evolve and change. Drawing on several intellectual traditions and methods, including those of social psychology, experimental economics and evolutionary game theory, Bicchieri provides an integrated account of how social norms emerge, why and when we follow them, and the situations where we are most (...) likely to focus on relevant norms. Examining the existence and survival of inefficient norms, she demonstrates how norms evolve in ways that depend upon the psychological dispositions of the individual and how such dispositions may impair social efficiency. By contrast, she also shows how certain psychological propensities may naturally lead individuals to evolve fairness norms that closely resemble those we follow in most modern societies. (shrink)

ABSTRACT Tetlock's Expert Political Judgment is a creative, careful, and mostly convincing study of the predictive accuracy of political experts. My only major complaints are that Tetlock (1) understates the predictive accuracy of experts, and (2) does too little to discourage demagogues from misinterpreting his work as a vindication of the wisdom of the average citizen. Experts have much to learn from Tetlock's epistemological audit, but there is still ample evidence that, compared to laymen, experts are very good.

For decades, scholars have recognized that most citizens have little or no political knowledge, and that it is in fact rational for the average voter to make little or no effort to acquire political information. Rational ignorance is fully compatible with the so‐called “paradox of voting” because it will often be rational for citizens to vote, but irrational for them to become well informed. Furthermore, rational ignorance leads not only to inadequate acquisition of political information, but also to ineffective use (...) of the information that citizens do possess. The combination of these two problems has fundamental implications for a variety of issues in public policy and international affairs. (shrink)

This book advances a theory of personal, public and political justification. Drawing on current work in epistemology and cognitive psychology, the work develops a theory of personally justified belief. Building on this account, it advances an account of public justification that is more normative and less "populist" than that of "political liberals." Following the social contract theories of Hobbes, Locke and Kant, the work then argues that citizens have conclusive reason to appoint an umpire to resolve disputes arising from inconclusive (...) public justifications. The rule of law, liberal democracy and limited judicial review are defended as elements of a publicly justified umpiring procedure. (shrink)

In response to the dozen essays published here, which relate my 1964 paper on “The Nature of Belief Systems in the Mass Publics” to normative requirements of democratic theory, I note, inter alia, a major misinterpretation of my old argument, as well as needed revisions of that argument in the light of intervening data. Then I address the degree to which there may be some long‐term secular change in the parameters that I originally laid out. In the final section, I (...) provide a case study of public understanding of factual trends in federal tax policy in recent decades which seems commendably veridical on average. The preferences of the public thereon add up to a remarkably clear popular mandate. But this mandate seems to disappear rather magically in the voting booth, probably due to a combination of limited contextual information on the public side, and considerable skill on the elite side in manipulating apparent political realities.

As a rule, Hayek has not been treated kindly by scholars. One would expect that a political theorist and economist of his stature would be charitably, if not sympathetically, read by commentators; instead, Hayek often elicits harsh dismissals. This is especially true of his fundamental ideas about the evolution of society and reason. A reader will find influential discussions in which his analysis is described as “dogmatic,” “unsophisticated,” and “crude.” In this chapter I propose to take a fresh start, sketching (...) a sympathetic interpretation of Hayek’s accounts of social evolution and mind as fundamental to his thinking. My basic claim is that Hayek’s views on social evolution and reason are not only intimately bound together, but they also depend on his analyses of complex orders, scientific explanations of such orders, and the place of rules in complex orders. Because so few commentators recognize that his claims about evolution are embedded in a system of ideas,1 most misunderstand him. (shrink)

When reasoning about deontic rules (what one may, should, or should not do in a given set of circumstances), reasoners adopt a violation‐detection strategy, a strategy they do not adopt when reasoning about indicative rules (descriptions of purported state of affairs). I argue that this indicative‐deontic distinction constitutes a primitive in the cognitive architecture. To support this claim, I show that this distinction emerges early in development, is observed regardless of the cultural background of the reasoner, and can be selectively (...) disrupted at the neurological level. I also argue that this distinction emerged as a result of selective pressure favouring the evolution of reasoning strategies that determine survival within dominance hierarchies. (shrink)

In simple action theory, when people choose between courses of action, they know what the outcome will be. When an individual is making a choice "against nature," such as switching on a light, that assumption may hold true. But in strategic interaction outcomes, indeterminacy is pervasive and often intractable. Whether one is choosing for oneself or making a choice about a policy matter, it is usually possible only to make a guess about the outcome, one based on anticipating what other (...) actors will do. In this book Russell Hardin asserts, in his characteristically clear and uncompromising prose, "Indeterminacy in contexts of strategic interaction... Is an issue that is constantly swept under the rug because it is often disruptive to pristine social theory. But the theory is fake: the indeterminacy is real." In the course of the book, Hardin thus outlines the various ways in which theorists from Hobbes to Rawls have gone wrong in denying or ignoring indeterminacy, and suggests how social theories would be enhanced--and how certain problems could be resolved effectively or successfully--if they assumed from the beginning that indeterminacy was the normal state of affairs, not the exception. Representing a bold challenge to widely held theoretical assumptions and habits of thought, Indeterminacy and Society will be debated across a range of fields including politics, law, philosophy, economics, and business management.

Liberal political theory is all too familiar with the divide between classical and welfare-state liberals. Classical liberals, as we all know, insist on the importance of small government, negative liberty, and private property. Welfare-state liberals, on the other hand, although they too stress civil rights, tend to be sympathetic to “positive liberty,” are for a much more expansive government, and are often ambivalent about private property. Although I do not go so far as to entirely deny the usefulness of this (...) familiar distinction, I think in many ways it is misleading. In an important sense, most free-market liberals are also “welfare-state” liberals. I say this because the overwhelming number of liberals, of both the pro-market and the pro-government variety, entertain a welfarist conception of political economy. On this dominant welfarist view, the ultimate justification of the politico-economic order is that it promotes human welfare. Traditional “welfare-state liberals” such as Robert E. Goodin manifestly adopt this welfarist conception. But it is certainly not only interventionists such as Goodin who insist that advancing welfare is the overriding goal of normative political economy. J. R. McCulloch, one of the great nineteenth-century laissez-faire political economists, was adamant that “freedom is not, as some appear to think, the end of government: the advancement of public prosperity and happiness is its end.” To be sure, McCulloch would have disagreed with Goodin about the optimal welfare-maximizing economic policy: the welfarist ideal, he and his fellow classical political economists believed, would best be advanced by provision of a legal and institutional framework — most importantly, the laws of property, contract, and the criminal code — that allows individuals to pursue their own interests in the market and, by so doing, promote public welfare. In general, what might be called the “classical-liberal welfare state” claims to advance welfare by providing the framework for individuals to seek wealth for themselves, while welfarists such as Goodin insist that a market order is seriously flawed as a mechanism for advancing human welfare and, in addition, that government has the competency to “correct market failures” in the provision of welfare.
