For multiple reasons, deliberating groups often converge on falsehood rather than truth. Individual errors may be amplified rather than cured. Group members may fall victim to a bad cascade, either informational or reputational. Deliberators may emphasize shared information at the expense of uniquely held information. Finally, group polarization may lead even rational people to unjustified extremism. By contrast, prediction markets often produce accurate results, because they create strong incentives for revelation of privately held knowledge and succeed in aggregating widely dispersed (...) information.

What is the relationship between fear, danger, and the law? Cass Sunstein attacks the increasingly influential Precautionary Principle - the idea that regulators should take steps to protect against potential harms, even if causal chains are uncertain and even if we do not know that harms are likely to come to fruition. Focusing on such problems as global warming, terrorism, DDT, and genetic engineering, Professor Sunstein argues that the Precautionary Principle is incoherent. Risks exist on all sides (...) of social situations, and precautionary steps create dangers of their own. Diverse cultures focus on very different risks, often because social influences and peer pressures accentuate some fears and reduce others. Instead of adopting the Precautionary Principle, Professor Sunstein argues for three steps: a narrow Anti-Catastrophe Principle, designed for the most serious risks; close attention to costs and benefits; and an approach called 'libertarian paternalism', designed to respect freedom of choice while also moving people in directions that will make their lives go better. He also shows how free societies can protect liberty amidst fears about terrorism and national security. Laws of Fear represents a major statement from one of the most influential political and legal theorists writing today. (shrink)

In recent years, 'nudge units' or 'behavioral insights teams' have been created in the United States, the United Kingdom, Germany, and other nations. All over the world, public officials are using the behavioral sciences to protect the environment, promote employment and economic growth, reduce poverty, and increase national security. In this book, Cass R. Sunstein, the eminent legal scholar and best-selling co-author of Nudge, breaks new ground with a deep yet highly readable investigation into the ethical issues surrounding (...) nudges, choice architecture, and mandates, addressing such issues as welfare, autonomy, self-government, dignity, manipulation, and the constraints and responsibilities of an ethical state. Complementing the ethical discussion, The Ethics of Influence: Government in the Age of Behavioral Science contains a wealth of new data on people's attitudes towards a broad range of nudges, choice architecture, and mandates.

Many millions of people hold conspiracy theories; they believe that powerful people have worked together in order to withhold the truth about some important practice or some terrible event. A recent example is the belief, widespread in some parts of the world, that the attacks of 9/11 were carried out not by Al Qaeda, but by Israel or the United States. Those who subscribe to conspiracy theories may create serious risks, including risks of violence, and the existence of such theories (...) raises significant challenges for policy and law. The first challenge is to understand the mechanisms by which conspiracy theories prosper; the second challenge is to understand how such theories might be undermined. Such theories typically spread as a result of identifiable cognitive blunders, operating in conjunction with informational and reputational influences. A distinctive feature of conspiracy theories is their self-sealing quality. Conspiracy theorists are not likely to be persuaded by an attempt to dispel their theories; they may even characterize that very attempt as further proof of the conspiracy. Because those who hold conspiracy theories typically suffer from a crippled epistemology, in accordance with which it is rational to hold such theories, the best response consists in cognitive infiltration of extremist groups. Various policy dilemmas, such as the question whether it is better for government to rebut conspiracy theories or to ignore them, are explored in this light. (shrink)

The most glamorous and even glorious moments in a legal system come when a high court recognizes an abstract principle involving, for example, human liberty or equality. Indeed, Americans, and not a few non-Americans, have been greatly stirred--and divided--by the opinions of the Supreme Court, especially in the area of race relations, where the Court has tried to revolutionize American society. But these stirring decisions are aberrations, says Cass R. Sunstein, and perhaps thankfully so. In Legal Reasoning and (...) Political Conflict, Sunstein, one of America's best known commentators on our legal system, offers a bold, new thesis about how the law should work in America, arguing that the courts best enable people to live together, despite their diversity, by resolving particular cases without taking sides in broader, more abstract conflicts. Sunstein offers a close analysis of the way the law can mediate disputes in a diverse society, examining how the law works in practical terms, and showing that, to arrive at workable, practical solutions, judges must avoid broad, abstract reasoning. Why? For one thing, critics and adversaries who would never agree on fundamental ideals are often willing to accept the concrete details of a particular decision. Likewise, a plea bargain for someone caught exceeding the speed limit need not--indeed, must not--delve into sweeping issues of government regulation and personal liberty. Thus judges purposely limit the scope of their decisions to avoid reopening large-scale controversies. Sunstein calls such actions incompletely theorized agreements. In identifying them as the core feature of legal reasoning--and as a central part of constitutional thinking in America, South Africa, and Eastern Europe-- he takes issue with advocates of comprehensive theories and systemization, from Robert Bork to Jeremy Bentham, the father of utilitarianism, and Ronald Dworkin, who defends an ambitious role for courts in the elaboration of rights. Equally important, Sunstein goes on to argue that it is the living practice of the nation's citizens that truly makes law. For example, he cites Griswold v. Connecticut, a groundbreaking case in which the Supreme Court struck down Connecticut's restrictions on the use of contraceptives by married couples--a law that was no longer enforced by prosecutors. In overturning the legislation, the Court invoked the abstract right of privacy; the author asserts that the justices should have appealed to the narrower principle that citizens need not comply with laws that lack real enforcement. By avoiding large-scale issues and values, such a decision could have led to a different outcome in Bowers v. Hardwick, the decision that upheld Georgia's rarely prosecuted ban on sodomy. And by pointing to the need for flexibility over time and circumstances, Sunstein offers a novel understanding of the old ideal of the rule of law. Legal reasoning can seem impenetrable, mysterious, baroque. This book helps dissolve the mystery. Whether discussing the interpretation of the Constitution or the spell cast by the revolutionary Warren Court, Cass Sunstein writes with grace and power, offering a striking and original vision of the role of the law in a diverse society. In his flexible, practical approach to legal reasoning, he moves the debate over fundamental values and principles out of the courts and back to its rightful place in a democratic state: the legislatures elected by the people.

With respect to questions of fact, people use heuristics – mental short-cuts, or rules of thumb, that generally work well, but that also lead to systematic errors. People use moral heuristics too – moral short-cuts, or rules of thumb, that lead to mistaken and even absurd moral judgments. These judgments are highly relevant not only to morality, but to law and politics as well. Examples are given from a number of domains, including risk regulation, punishment, reproduction and sexuality, and the (...) act/omission distinction. In all of these contexts, rapid, intuitive judgments make a great deal of sense, but sometimes produce moral mistakes that are replicated in law and policy. One implication is that moral assessments ought not to be made by appealing to intuitions about exotic cases and problems; those intuitions are particularly unlikely to be reliable. Another implication is that some deeply held moral judgments are unsound if they are products of moral heuristics. The idea of error-prone heuristics is especially controversial in the moral domain, where agreement on the correct answer may be hard to elicit; but in many contexts, heuristics are at work and they do real damage. Moral framing effects, including those in the context of obligations to future generations, are also discussed. (shrink)

This is a compelling if sober set of questions from America's foremost legal scholar."--Lawrence Lessig, Stanford University.

Cass Sunstein and Martha Nussbaum bring together an all-star cast of contributors to explore the legal and political issues that underlie the campaign for animal rights and the opposition to it. Addressing ethical questions about ownership, protection against unjustified suffering, and the ability of animals to make their own choices free from human control, the authors offer numerous different perspectives on animal rights and animal welfare. They show that whatever one's ultimate conclusions, the relationship between human beings and (...) nonhuman animals is being fundamentally rethought.

This essay has three general themes. The first involves the claim that nudging threatens human agency. My basic response is that human agency is fully retained (because nudges do not compromise freedom of choice) and that agency is always exercised in the context of some kind of choice architecture. The second theme involves the importance of having a sufficiently capacious sense of the category of nudges, and a full appreciation of the differences among them. Some nudges either enlist or combat (...) behavioral biases but others do not, and even among those that do enlist or combat such biases, there are significant differences. The third general theme is the need to bring various concerns (including ethical ones) in close contact with particular examples. A legitimate point about default rules may not apply to warnings or reminders. An ethical objection to the use of social norms may not apply to information disclosure. Here as elsewhere, abstraction can be a trap. We continue to learn about the relevant ethical issues, about likely public reactions to nudging, and about differences across cultures and nations. Future progress will depend on a high level of concreteness, perhaps especially in dealing with the vexing problem of time-inconsistency. (shrink)

The topic is highly relevant to the debate over “communitarianism.” Manycommunitarians appear to be traditionalists, at least implicitly; they are concerned to defend social practices against abstract, acontextual claims about what is to be done, or about “rights.” It is important to ask why and when communitarians believethat a community's practices deserve insulation from rights–based claims. Often the best or most interesting answer has a Burkean dimension. It involves the extent to which a community—perhaps a local community resisting national efforts, perhaps a nation resisting international goals—owes its practices to long traditions that, precisely because of their longevity, might seem to make special sense. Ideas of this sort might be thought to have special strength when we think about rights in general or about constitutional rights in particular. (shrink)

We are in the midst of a worldwide debate over whether there should be "more" or "less" government.

How is constitutionalism possible, when people disagree on so many questions about what is good and what is right? The answer lies in two kinds of incompletely theorized agreement - both reached amidst the sharpest disagreements about the fundamental issues in social life. The first consist of agreements on abstract formulations ; these agreements are crucial to constitution-making as a social practice. The second consist of agreements on particular doctrines and practices; these agreements are crucial to life and law under (...) existing constitutions. Incompletely theorized agreements help illuminate an enduring constitutional puzzle: how members of diverse societies can work together on terms of mutual respect amidst intense disagreements about both the right and the good. Such agreements help make constitutions and constitutional law possible, even within nations whose citizens cannot concur on the most fundamental matters. (shrink)

_ Source: _Volume 10, Issue 3, pp 433 - 440 Historical explanations are a form of counterfactual history.

There has been considerable recent discussion of the social effects of “liberalism,” which are said to include a growth in out-of-wedlock childbirth, repudiation of traditions, a rise in populism, increased reliance on technocracy, inequality, environmental degradation, sexual promiscuity, deterioration of civic associations, a diminution of civic virtue, political correctness on university campuses, and a general sense of alienation. There is good reason for skepticism about these claims. Liberalism is not a person, and it is not an agent in history. Claims (...) about the supposedly adverse social effects of liberalism are best taken not as causal claims at all, but as normative objections that should be defended on their merits. These propositions are elaborated with reference to three subordinate propositions: liberalism, as such, does not lack the resources to defend traditions; liberalism, as such, hardly rejects the idea of “constraint,” though the domains in which liberals accept constraints differ from those of antiliberals, and vary over time; liberalism, as such, does not dishonor the idea of “honor.” There is a general point here about the difficulty of demonstrating, and the potential recklessness of claiming, that one or another “ism” is causally associated with concrete social developments.

Markets, it is sometimes said, are hard on discrimination. An employer who finds himself refusing to hire qualified blacks and women will, in the long run, lose out to those who are willing to draw from a broader labor pool. Employer discrimination amounts to a self-destructive “taste” – self-destructive because employers who indulge that taste add to the costs of doing business. Added costs can only hurt. To put it simply, bigots are weak competitors. The market will drive them out.On (...) this account, the persistence of employment discrimination on the basis of race and sex presents something of a puzzle. And if markets are an ally of equality and a foe of employment discrimination, perhaps discrimination persists because of something other than markets. Perhaps labor unions are to blame; perhaps the real culprit is the extensive federal regulation of the employment market, including minimum-wage and maximum-hour laws and unemployment compensation. If competitive markets drive out discrimination, the problem for current federal policy lies not in the absence of aggressive anti-discrimination law, but instead in the absence of truly competitive markets.If this account is correct, the prescription for the future of anti-discrimination law is to seek ways to free up employers from the wide range of governmental disabilities – including, in fact, anti-discrimination law itself. The argument seems to be bolstered by the fact that some groups subject to past and present prejudice – most notably, Jews and Asian-Americans – have made substantial progress in employment at least in part because of the operation of competitive markets.

This volume collects some of today's most original and important work at the intersection of feminism and political theory. A representative and wide-ranging set of readings on feminist political thought, the authors provide large-scale critiques, and in some instances reconstructions, of important strains in political thought, including notions of equality, rights-based justice, and contract theories. The fourteen essays are organized around four major themes: "The Question of a Different Voice: Care, Justice, and Rights," "Equality and Inequality in Politics and Elsewhere," (...) "Coercion versus Consent, Public versus Private, and Sexuality," and "Trust and Responsibility.". (shrink)

Robert Crandall writes as if the regulatory state is a simple failure. In fact, however, from the economic point of view there have been many successes, in the form of regulations whose benefits exceed their costs. Moreover, economic criteria are inadequate for evaluating regulatory performance, since even well?aggregated private willingness to pay provides a poor basis for assessing government regulation. It is now necessary to move beyond sterile debates about whether regulation is desirable; nonregulation is not an option, since laissez (...) faire is itself a regulatory system. Democratic, economic, and constitutional criteria hold out the promise of much better regulatory tools, in the form of flexible incentives rather than rigid commands. (shrink)

Chater & Loewenstein, superb and distinguished social scientists, have misfired. Their complaint is baseless: In the real world of policymaking, behavioral science is mostly being used to reform systems, not to alter individual behavior. Nor is there empirical support for the proposition that interventions aimed at helping individuals make systemic reform less likely.

This is a selection of the most important work of Edna Ullmann-Margalit, an unorthodox and deeply original philosopher whose work illuminated the largest mysteries of human life.

Since America's founding, the U.S. Supreme Court had issued a vast number of decisions on a staggeringly wide variety of subjects. And hundreds of judges have occupied the bench. Yet as Cass R. Sunstein, the eminent legal scholar and bestselling co-author of Nudge, points out, almost every one of the Justices fits into a very small number of types regardless of ideology: the hero, the soldier, the minimalist, and the mute. Heroes are willing to invoke the Constitution to (...) invalidate state laws, federal legislation, and prior Court decisions. They loudly embrace first principles and are prone to flair, employing dramatic language to fundamentally reshape the law. Soldiers, on the other hand, are skeptical of judicial power, and typically defer to decisions made by the political branches. Minimalists favor small steps and only incremental change. They worry that bold reversals of long-established traditions may be counterproductive, producing a backlash that only leads to another reversal. Mutes would rather say nothing at all about the big constitutional issues, and instead tend to decide cases on narrow grounds or keep controversial cases out of the Court altogether by denying standing. As Sunstein shows, many of the most important constitutional debates are in fact contests between the four Personae. Whether the issue involves slavery, gender equality, same-sex marriage, executive power, surveillance, or freedom of speech, debates have turned on choices made among the four Personae--choices that derive as much from psychology as constitutional theory. Sunstein himself defends a form of minimalism, arguing that it is the best approach in a self-governing society of free people. More broadly, he casts a genuinely novel light on longstanding disputes over the proper way to interpret the constitution, demonstrating that behind virtually every decision and beneath all of the abstract theory lurk the four Personae. By emphasizing the centrality of character types, Sunstein forces us to rethink everything we know about how the Supreme Court works. (shrink)

Legal systems must proceed in the face of two conceptions of procedural fairness. The first, embodied in the rule of law ideal, calls for clear rules, laid down in advance and susceptible to mechanical application in individual cases. The second calls for a high degree of individuation, on the theory that fairness requires particularized consideration of the whole person. Both conceptions can be found in judicial interpretation of the due process clause of the American Constitution, which sometimes requires rule-bound decisions, (...) and sometimes requires individuation. Both conceptions have a great deal of appeal in particular settings. The choice between the two depends largely on an investigation of the costs of decision and the costs of error. In addition, "planning costs" play a large role; where people need to be able to plan in advance, rule-bound judgments look fairer and much more attractive even if they produce significant unfairness and arbitrariness.
