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 (who champions the original understanding of the Constitution) 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.

The rise of the "information society" offers not only considerable peril but also great promise. Beset from all sides by a never-ending barrage of media, how can we ensure that the most accurate information emerges and is heeded? In this book, Cass R. Sunstein develops a deeply optimistic understanding of the human potential to pool information, and to use that knowledge to improve our lives. In an age of information overload, it is easy to fall back on our own prejudices and insulate ourselves with comforting opinions that reaffirm our core beliefs. Crowds quickly become mobs. The justification for the Iraq war, the collapse of Enron, the explosion of the space shuttle Columbia--all of these resulted from decisions made by leaders and groups trapped in "information cocoons," shielded from information at odds with their preconceptions. How can leaders and ordinary people challenge insular decision making and gain access to the sum of human knowledge? Stunning new ways to share and aggregate information, many Internet-based, are helping companies, schools, governments, and individuals not only to acquire, but also to create, ever-growing bodies of accurate knowledge. Through a ceaseless flurry of self-correcting exchanges, wikis, covering everything from politics and business plans to sports and science fiction subcultures, amass--and refine--information. Open-source software enables large numbers of people to participate in technological development. Prediction markets aggregate information in a way that allows companies, ranging from computer manufacturers to Hollywood studios, to make better decisions about product launches and office openings. Sunstein shows how people can assimilate aggregated information without succumbing to the dangers of the herd mentality--and when and why the new aggregation techniques are so astoundingly accurate. In a world where opinion and anecdote increasingly compete on equal footing with hard evidence, the on-line effort of many minds coming together might well provide the best path to infotopia.

How does group behavior drive extremism and challenge democratic values? Cass R. Sunstein argues that the key to preventing the spread of extremist views is not to suppress deliberation among the like-minded; such groups productively challenge conventional thinking and majority opinion. Instead, policymakers should develop institutions to ensure that like-minded groups encounter a diversity of opinions within civil society. The goal, Sunstein contends, must be to create opportunities for civil deliberation that expose like-minded group members to opposing views, while exposing society at large to the views of such groups.

Simpler government arrived four years ago. It helped put money in your pocket. It saved hours of your time. It improved your children’s diet, lengthened your life span, and benefited businesses large and small. It did so by issuing fewer regulations, by insisting on smarter regulations, and by eliminating or improving old regulations. Cass R. Sunstein, as administrator of the most powerful White House office you’ve never heard of, oversaw it and explains how it works, why government will never be the same again (thank goodness), and what must happen in the future. Cutting-edge research in behavioral economics has influenced business and politics. Long at the forefront of that research, Sunstein, for three years President Obama’s “regulatory czar” heading the White House Office of Information and Regulatory Affairs, oversaw a far-reaching restructuring of America’s regulatory state. In this highly anticipated book, Sunstein pulls back the curtain to show what was done, why Americans are better off as a result, and what the future has in store. The evidence is all around you, and more is coming soon. Simplified mortgages and student loan applications. Scorecards for colleges and universities. Improved labeling of food and energy-efficient appliances and cars. Calories printed on chain restaurant menus. Healthier food in public schools. Backed by historic executive orders ensuring transparency and accountability, simpler government can be found in new initiatives that save money and time, improve health, and lengthen lives. Simpler: The Future of Government will transform what you think government can and should accomplish.

Why the separation of powers is essential to liberty and democracy. From the winner of the Holberg Prize and New York Times–bestselling author of The World According to Star Wars. All over the world, people are questioning the separation of powers. They want a strong man, able to do what must be done. But James Madison was right to say this: “The accumulation of all powers, legislative, executive, and judiciary, in the same hands, whether of one, a few, or many, and whether hereditary, self-appointed, or elective, may justly be pronounced the very definition of tyranny.” In this essential and immensely timely book, Separation of Powers, Cass Sunstein explains why the separation of powers is necessary for both freedom and self-government. He shows that freedom from fear is a central goal of the system of separation of powers. He also explains why the executive branch is the most dangerous branch, why the idea of presidential immunity is a terrible one, and why an independent judiciary is crucial. Drawing on his extensive experience in the White House, the Department of Justice, and the Department of Homeland Security, the author also argues that the separation of powers is, in fact, six separations of powers: (1) The legislature may not exercise the executive power. (2) The legislature may not exercise the judicial power. (3) The executive may not exercise the legislative power. (4) The executive may not exercise the judicial power. (5) The judiciary may not exercise the legislative power. (6) The judiciary may not exercise the executive power. Each of these is essential to liberty under law.

Nuclear bombs in suitcases, anthrax bacilli in ventilators, tsunamis and meteors, avian flu, scorchingly hot temperatures: nightmares that were once the plot of Hollywood movies are now frighteningly real possibilities. How can we steer a path between willful inaction and reckless overreaction? Cass Sunstein explores these and other worst-case scenarios and how we might best prevent them in this vivid, illuminating, and highly original analysis. Singling out the problems of terrorism and climate change, Sunstein explores our susceptibility to two opposite and unhelpful reactions: panic and utter neglect. He shows how private individuals and public officials might best respond to low-probability risks of disaster—emphasizing the need to know what we will lose from precautions as well as from inaction. Finally, he offers an understanding of the uses and limits of cost–benefit analysis, especially when current generations are imposing risks on future generations. Throughout, Sunstein uses climate change as a defining case, because it dramatically illustrates the underlying principles. But he also discusses terrorism, depletion of the ozone layer, genetic modification of food, hurricanes, and worst-case scenarios faced in our ordinary lives. Sunstein concludes that if we can avoid the twin dangers of overreaction and apathy, we will be able to ameliorate if not avoid future catastrophes, retaining our sanity as well as scarce resources that can be devoted to more constructive ends.

This text shows us how to approach the Internet as responsible people. Democracy, it maintains, depends on shared experiences and requires people to be exposed to topics and ideas that they would not have chosen in advance.

An updated and refreshed edition of the groundbreaking book that shows how people can be nudged toward decisions that will improve their lives "If you''ve read Nudge and think you fully grasp the concept and its uses, you are mistaken. The new edition significantly deepened my understanding of what nudges are and how they can be employed. It truly is a must-read."―Robert Cialdini, New York Times bestselling author of Influence "Few books can be said to have changed the world, but Nudge did. The Final Edition is marvelous: funny, useful, and wise."―Daniel Kahneman, #1 New York Times bestselling author of Thinking, Fast and Slow Since the original publication of Nudge more than a decade ago, the word "nudge" has entered the vocabulary of businesspeople, policymakers, engaged citizens, and consumers everywhere. The book has given rise to more than 200 "nudge units" in governments around the world and countless groups of behavioral scientists in every part of the economy. It has taught us how to use thoughtful "choice architecture"--a concept the authors invented--to help us make better decisions for ourselves, our families, and our society. Now, the authors have rewritten the book from cover to cover, making use of their experiences in and out of government over the past dozen years as well as the explosion of new research in numerous academic disciplines. It offers a wealth of new insights, for both its avowed fans and newcomers to the field, about a wide variety of issues that we face in our daily lives--COVID-19, health, personal finance, retirement savings, credit card debt, home mortgages, medical care, organ donation, climate change, and "sludge" (paperwork and other nuisances that we don''t want and keep us from getting what we do want)--all while honoring one of the cardinal rules of nudging: make it fun!

A Forbes Best Higher Education Book of the Year From renowned legal scholar Cass R. Sunstein, a concise, case-by-case guide to resolving free-speech dilemmas at colleges and universities. Free speech is indispensable on college campuses: allowing varied views and frank exchanges of opinion is a core component of the educational enterprise and the pursuit of truth. But free speech does not mean a free-for-all. The First Amendment prohibits “abridging the freedom of speech,” yet laws against perjury or bribery, for example, are still constitutional. In the same way, valuing freedom of speech does not stop a university from regulating speech when doing so is necessary for its educational mission. So where is the dividing line? How can we distinguish reasonable restrictions from impermissible infringement? In this pragmatic, no-nonsense explainer, Cass Sunstein takes us through a wide range of scenarios involving students, professors, and administrators. He discusses why it’s consistent with the First Amendment to punish students who shout down a speaker, but not those who chant offensive slogans; why a professor cannot be fired for writing a politically charged op-ed, yet a university might legitimately consider an applicant’s political views when deciding whether to hire her. He explains why private universities are not legally bound by the First Amendment yet should, in most cases, look to follow it. And he addresses the thorny question of whether a university should officially take sides on public issues or deliberately keep the institution outside the fray. At a time when universities are assailed on free-speech grounds from both left and right, Campus Free Speech: A Pocket Guide is an indispensable resource for cutting through the noise and understanding the key issues animating the debates.

An “illuminating” study that reveals the different ways social change occurs—for readers of Freakonomics and Thinking, Fast and Slow (The New York Times) How does social change happen? When do social movements take off? Sexual harassment was once something that women had to endure; now a movement has risen up against it. White nationalist sentiments, on the other hand, were largely kept out of mainstream discourse; now there is no shortage of media outlets for them. In this book, with the help of behavioral economics, psychology, and other fields, Cass Sunstein casts a bright new light on how change happens. Sunstein focuses on the crucial role of social norms—and on their frequent collapse. When norms lead people to silence themselves, even an unpopular status quo can persist. Then one day, someone challenges the norm—a child who exclaims that the emperor has no clothes; a woman who says “me too.” Sometimes suppressed outrage is unleashed, and long-standing practices fall. Sometimes change is more gradual, as “nudges” help produce new and different decisions—apps that count calories; texted reminders of deadlines; automatic enrollment in green energy or pension plans. Sunstein explores what kinds of nudges are effective and shows why nudges sometimes give way to bans and mandates. Finally, he considers social divisions, social cascades, and “partyism,” when identification with a political party creates a strong bias against all members of an opposing party—which can both fuel and block social change.

A collection of controversial essays touches upon an array of issues, from marriage equality and conspiracy theories to animal rights.

Why do people become extremists? What makes people become so dismissive of opposing views? Why is political and cultural polarization so pervasive in America? In Going to Extremes, renowned legal scholar and best-selling author Cass R. Sunstein offers startling insights into why and when people gravitate toward extremism. Sunstein marshals a wealth of evidence that shows that when like-minded people gather in groups, they tend to become more extreme in their views than they were before. Thus when liberals group get together to debate climate change, they end up more alarmed about climate change, while conservatives brought together to discuss same-sex unions become more set against same-sex unions. In courtrooms, radio stations, and chatrooms, enclaves of like-minded people are breeding ground for extreme movements. Indeed, Sunstein shows that a good way to create an extremist group, or a cult of any kind, is to separate members from the rest of society, either physically or psychologically. Sunstein''s findings help to explain such diverse phenomena as political outrage on the Internet, unanticipated "blockbusters" in the film and music industry, the success of the disability rights movement, ethnic conflict in Iraq and former Yugoslavia, and Islamic terrorism. Providing a wealth of real-world examples--sometimes entertaining, sometimes alarming--Sunstein offers a fresh explanation of why partisanship has become so bitter and debate so rancorous in America and abroad. Praise for the hardcover: "A path-breaking exploration of the perils and possibilities created by polarization among the like-minded." --Kathleen Hall Jamieson, co-author of unSpun and Echo Chamber "Poses a powerful challenge to anyone concerned with the future of our democracy. He reveals the dark side to our cherished freedoms of thought, expression and participation. Initiates an urgent dialogue which any thoughtful citizen should be interested in." --James S. Fishkin, author of When the People Speak

Our ability to make choices is fundamental to our sense of ourselves as human beings, and essential to the political values of freedom-protecting nations. Whom we love; where we work; how we spend our time; what we buy; such choices define us in the eyes of ourselves and others, and much blood and ink has been spilt to establish and protect our rights to make them freely. Choice can also be a burden. Our cognitive capacity to research and make the best decisions is limited, so every active choice comes at a cost. In modern life the requirement to make active choices can often be overwhelming. So, across broad areas of our lives, from health plans to energy suppliers, many of us choose not to choose. By following our default options, we save ourselves the costs of making active choices. By setting those options, governments and corporations dictate the outcomes for when we decide by default. This is among the most significant ways in which they effect social change, yet we are just beginning to understand the power and impact of default rules. Many central questions remain unanswered: When should governments set such defaults, and when should they insist on active choices? How should such defaults be made? What makes some defaults successful while others fail? Cass R. Sunstein has long been at the forefront of developing public policy and regulation to use government power to encourage people to make better decisions. In this major new book, Choosing Not to Choose, he presents his most complete argument yet for how we should understand the value of choice, and when and how we should enable people to choose not to choose. The onset of big data gives corporations and governments the power to make ever more sophisticated decisions on our behalf, defaulting us to buy the goods we predictably want, or vote for the parties and policies we predictably support. As consumers we are starting to embrace the benefits this can bring. But should we? What will be the long-term effects of limiting our active choices on our agency? And can such personalized defaults be imported from the marketplace to politics and the law? Confronting the challenging future of data-driven decision-making, Sunstein presents a manifesto for how personalized defaults should be used to enhance, rather than restrict, our freedom and well-being.

NEW YORK TIMES BESTSELLER #1 Washington Post Bestseller There''s Santa Claus, Shakespeare, Mickey Mouse, the Bible, and then there''s Star Wars. Nothing quite compares to sitting down with a young child and hearing the sound of John Williams''s score as those beloved golden letters fill the screen. In this fun, erudite, and often moving book, Cass R. Sunstein explores the lessons of Star Wars as they relate to childhood, fathers, the Dark Side, rebellion, and redemption. As it turns out, Star Wars also has a lot to teach us about constitutional law, economics, and political uprisings. In rich detail, Sunstein tells the story of the films'' wildly unanticipated success and explores why some things succeed while others fail. Ultimately, Sunstein argues, Star Wars is about freedom of choice and our never-ending ability to make the right decision when the chips are down. Written with buoyant prose and considerable heart, The World According to Star Wars shines a bright new light on the most beloved story of our time.

In this groundbreaking book, eminent legal scholar Cass Sunstein argues that in every era, constitutional debates are, in fact, contests between four different types of ''Constitutional Personae'' - Heroes, Soldiers, Minimalists, and Mutes.

The New York Times–bestselling author of Nudge examines the prevelance and burden of ‘sludge’—red tape and unnecessary paperwork—and why we must do better. “If nudges have a mortal enemy, or perhaps the equivalent of antimatter to matter, it’s ‘sludge’.” —Forbes We’ve all had to fight our way through administrative sludge—filling out complicated online forms, mailing in paperwork, standing in line at the motor vehicle registry. This kind of red tape is a nuisance, but, as Cass Sunstein shows in Sludge, it can also impair health, reduce growth, entrench poverty, and exacerbate inequality. Confronted by sludge, people just give up—and lose a promised outcome: a visa, a job, a permit, an educational opportunity, necessary medical help. In this lively and entertaining look at the terribleness of sludge, Sunstein explains what we can do to reduce it. Because of sludge, Sunstein, explains, too many people don''t receive benefits to which they are entitled. Sludge even prevents many people from exercising their constitutional rights—when, for example, barriers to voting in an election are too high. (A Sludge Reduction Act would be a Voting Rights Act.) Sunstein takes readers on a tour of the not-so-wonderful world of sludge, describes justifications for certain kinds of sludge, and proposes “Sludge Audits” as a way to measure the effects of sludge. On balance, Sunstein argues, sludge infringes on human dignity, making people feel that their time and even their lives don''t matter. We must do better.
