Nudge: Improving Decisions About Health, Wealth, and Happiness

by Cass R. Sunstein, Richard H. Thaler

A New York Times bestseller with more than 1.5 million copies sold

Named a Best Book of the Year by the Economist and the Financial Times

“An essential read . . . loaded with good ideas that financial-service executives, policy makers, Wall Street mavens, and all savers can use.”—John F. Wasik, Boston Globe

“Save the planet, save yourself. Do-gooders, policymakers, this one's for you.”—Newsweek

Every day, we make decisions on topics ranging from personal investments to schools for our children to the meals we eat to the causes we champion. Unfortunately, we often choose poorly. Nobel laureate Richard Thaler and legal scholar and bestselling author Cass Sunstein explain in this important exploration of choice architecture that, being human, we all are susceptible to various biases that can lead us to blunder. Our mistakes make us poorer and less healthy; we often make bad decisions involving education, personal finance, health care, mortgages and credit cards, the family, and even the planet itself.

In Nudge, Thaler and Sunstein invite us to enter an alternative world, one that takes our humanness as a given. They show that by knowing how people think, we can design choice environments that make it easier for people to choose what is best for themselves, their families, and their society. Using colorful examples from the most important aspects of life, Thaler and Sunstein demonstrate how thoughtful “choice architecture” can be established to nudge us in beneficial directions without restricting freedom of choice. Nudge offers a unique new take—from neither the left nor the right—on many hot-button issues, for individuals and governments alike. This is one of the most engaging and provocative books to come along in many years.

Nudge: Improving Decisions About Health, Wealth, and Happiness

by Cass R. Sunstein, Richard H. Thaler

Now available: Nudge: The Final Edition

The original edition of the multimillion-copy New York Times bestseller by the winner of the Nobel Prize in Economics, Richard H. Thaler, and Cass R. Sunstein: a revelatory look at how we make decisions—for fans of Malcolm Gladwell’s Blink, Charles Duhigg’s The Power of Habit, James Clear’s Atomic Habits, and Daniel Kahneman’s Thinking, Fast and Slow

Named a Best Book of the Year by TheEconomist and the Financial Times

Every day we make choices—about what to buy or eat, about financial investments or our children’s health and education, even about the causes we champion or the planet itself. Unfortunately, we often choose poorly. Nudge is about how we make these choices and how we can make better ones. Using dozens of eye-opening examples and drawing on decades of behavioral science research, Nobel Prize winner Richard H. Thaler and Harvard Law School professor Cass R. Sunstein show that no choice is ever presented to us in a neutral way, and that we are all susceptible to biases that can lead us to make bad decisions. But by knowing how people think, we can use sensible “choice architecture” to nudge people toward the best decisions for ourselves, our families, and our society, without restricting our freedom of choice.

Noise: A Flaw in Human Judgment

by Daniel Kahneman, Olivier Sibony, Cass R. Sunstein

NEW YORK TIMES BESTSELLER

From the Nobel Prize-winning author of Thinking, Fast and Slow and the coauthor of Nudge, a revolutionary exploration of why people make bad judgments and how to make better ones—"a tour de force” (New York Times).

Imagine that two doctors in the same city give different diagnoses to identical patients—or that two judges in the same courthouse give markedly different sentences to people who have committed the same crime. Suppose that different interviewers at the same firm make different decisions about indistinguishable job applicants—or that when a company is handling customer complaints, the resolution depends on who happens to answer the phone. Now imagine that the same doctor, the same judge, the same interviewer, or the same customer service agent makes different decisions depending on whether it is morning or afternoon, or Monday rather than Wednesday. These are examples of noise: variability in judgments that should be identical.

In Noise, Daniel Kahneman, Olivier Sibony, and Cass R. Sunstein show the detrimental effects of noise in many fields, including medicine, law, economic forecasting, forensic science, bail, child protection, strategy, performance reviews, and personnel selection. Wherever there is judgment, there is noise. Yet, most of the time, individuals and organizations alike are unaware of it. They neglect noise. With a few simple remedies, people can reduce both noise and bias, and so make far better decisions.

Packed with original ideas, and offering the same kinds of research-based insights that made Thinking, Fast and Slow and Nudge groundbreaking New York Times bestsellers, Noise explains how and why humans are so susceptible to noise in judgment—and what we can do about it.

Can It Happen Here?: Authoritarianism in America

by Cass R. Sunstein

“What makes Trump immune is that he is not a president within the context of a healthy Republican government. He is a cult leader of a movement that has taken over a political party – and he specifically campaigned on a platform of one-man rule. This fact permeates “Can It Happen Here? . . . which concludes, if you read between the lines, that “it” already has.” – New York Times Book Review
From New York Times bestselling author Cass R. Sunstein, a compelling collection of essays by the brightest minds in America on authoritarianism.

With the election of Donald J. Trump, many people on both the left and right feared that America’s 240-year-old grand experiment in democracy was coming to an end, and that Sinclair Lewis’ satirical novel, It Can’t Happen Here, written during the dark days of the 1930s, could finally be coming true. Is the democratic freedom that the United States symbolizes really secure? Can authoritarianism happen in America?
Acclaimed legal scholar, Harvard Professor, and New York Times bestselling author Cass R. Sunstein queried a number of the nation’s leading thinkers. In this thought-provoking collection of essays, these distinguished thinkers and theorists explore the lessons of history, how democracies crumble, how propaganda works, and the role of the media, courts, elections, and "fake news" in the modern political landscape—and what the future of the United States may hold.

The World According to Star Wars

by Cass R. Sunstein

“Irresistibly charming, acclaimed legal scholar Sunstein writes partly as a rigorous academic and partly as a helpless fanboy as he explores our fascination with Star Wars and what the series can teach us about the law, behavioral economics, history, and even fatherhood. This book is fun, brilliant, and deeply original.”—Lee Child

The New York Times and Washington Post bestseller, fully revised and updated.
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.

Too Much Information: Understanding What You Don't Want to Know

by Cass R. Sunstein

How information can make us happy or miserable, and why we sometimes avoid it and sometimes seek it out.
How much information is too much? Do we need to know how many calories are in the giant vat of popcorn that we bought on our way into the movie theater? Do we want to know if we are genetically predisposed to a certain disease? Can we do anything useful with next week's weather forecast for Paris if we are not in Paris? In Too Much Information, Cass Sunstein examines the effects of information on our lives. Policymakers emphasize “the right to know,” but Sunstein takes a different perspective, arguing that the focus should be on human well-being and what information contributes to it. Government should require companies, employers, hospitals, and others to disclose information not because of a general “right to know” but when the information in question would significantly improve people's lives.
Sunstein argues that the information on warnings and mandatory labels is often confusing or irrelevant, yielding no benefit. He finds that people avoid information if they think it will make them sad (and seek information they think will make them happy). Our information avoidance and information seeking is notably heterogeneous—some of us do want to know the popcorn calorie count, others do not. Of course, says Sunstein, we are better off with stop signs, warnings on prescriptions drugs, and reminders about payment due dates. But sometimes less is more. What we need is more clarity about what information is actually doing or achieving.

Climate Justice: What Rich Nations Owe the World―and the Future

by Cass R. Sunstein

The social cost of carbon: The most important number you've never heard of—and what it means.

If you're injuring someone, you should stop—and pay for the damage you've caused. Why, this book asks, does this simple proposition, generally accepted, not apply to climate change? In Climate Justice, a bracing challenge to status-quo thinking on the ethics of climate change, renowned author and legal scholar Cass Sunstein clearly frames what’s at stake and lays out the moral imperative: When it comes to climate change, everyone must be counted equally, regardless of when they live or where they live—which means that wealthy nations, which have disproportionately benefited from greenhouse gas emissions, are obliged to help future generations and people in poor nations that are particularly vulnerable.

Invoking principles of corrective justice and distributive justice, Sunstein argues that rich countries should pay for the harms that they have caused and that all of us are obliged to take steps to protect future generations from serious climate-related damage. He shows how “choice engines,” informed by artificial intelligence, can enable people to save money and to reduce the harms they produce. The book casts new light on the “social cost of carbon,” the most important number in climate change debates—and explains how intergenerational neutrality and international neutrality can help all nations, above all the United States and China, do what must be done.

Liars: Falsehoods and Free Speech in an Age of Deception (Inalienable Rights)

by Cass R. Sunstein

A powerful analysis of why lies and falsehoods spread so rapidly now, and how we can reform our laws and policies regarding speech to alleviate the problem.

Lying has been with us from time immemorial. Yet today is different-and in many respects worse. All over the world, people are circulating damaging lies, and these falsehoods are amplified as never before through powerful social media platforms that reach billions. Liars are saying that COVID-19 is a hoax. They are claiming that vaccines cause autism. They are lying about public officials and about people who aspire to high office. They are lying about their friends and neighbors. They are trying to sell products on the basis of untruths. Unfriendly governments, including Russia, are circulating lies in order to destabilize other nations, including the United Kingdom and the United States. In the face of those problems, the renowned legal scholar Cass Sunstein probes the fundamental question of how we can deter lies while also protecting freedom of speech.

To be sure, we cannot eliminate lying, nor should we try to do so. Sunstein shows why free societies must generally allow falsehoods and lies, which cannot and should not be excised from democratic debate. A main reason is that we cannot trust governments to make unbiased judgments about what counts as "fake news." However, governments should have the power to regulate specific kinds of falsehoods: those that genuinely endanger health, safety, and the capacity of the public to govern itself. Sunstein also suggests that private institutions, such as Facebook and Twitter, have a great deal of room to stop the spread of falsehoods, and they should be exercising their authority far more than they are now doing. As Sunstein contends, we are allowing far too many lies, including those that both threaten public health and undermine the foundations of democracy itself.

Impeachment: A Citizen's Guide

by Cass R. Sunstein

“With insight, wisdom, affection, and concern, Sunstein has written the story of impeachment every citizen needs to know. This is a remarkable, essential book.” —Doris Kearns Goodwin

No one is above the law, not even the president. Impeachment is the most potent tool the founders gave us to ensure it, and yet few of us even know how it works.

As Benjamin Franklin famously put it, Americans have a republic, if we can keep it. Preserving the Constitution and the democratic system it supports is the public's responsibility. One route the Constitution provides for discharging that duty--a route rarely traveled--is impeachment. Expanding beyond violations of the law, impeachment was meant to defend against any action that would undermine the foundations of our republic.

Harvard Law professor Cass R. Sunstein provides a succinct citizen's guide to this essential tool of self-government. Taking us deeper than mere partisan politics, he illuminates the constitutional design behind impeachment and emphasizes the people's role in holding presidents accountable. In spite of the loud national debate over whether or not the House is right to impeach Trump, impeachment itself remains widely misunderstood. Sunstein identifies and corrects a number of common misconceptions, and describes how impeachment helps is an essential piece of our constitutional order, and a crucial part of the framers' decision to install an empowered executive in a nation deeply fearful of kings.

With an eye toward the past and the future, Impeachment: A Citizen's Guide considers a host of actual and imaginable arguments for a president's removal, explaining why some cases are easy and others hard, why some arguments for impeachment have been judicious and others not. And with an afterword and appendix on the current impeachment, it puts the national debate in its proper historical context. In direct and approachable terms, it is a guide through the treacherous waters of the impeachment process so that Americans of all political convictions may use their ultimate civic authority wisely.

Nudge: The Final Edition

by Cass R. Sunstein, Richard H. Thaler

*Once again a New York Times bestseller! First the original edition, and now the new Final Edition*

An essential new edition―revised and updated from cover to cover―of one of the most important books of the last two decades, by Nobel Prize winner Richard H. Thaler and Cass R. Sunstein

More than 2 million copies sold

Since the original publication of Nudge more than a decade ago, the title has entered the vocabulary of businesspeople, policy makers, engaged citizens, and consumers everywhere. The book has given rise to more than 400 “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 an explosion of new research in numerous academic disciplines. To commit themselves to never undertaking this daunting task again, they are calling this the “final edition.” 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 we don’t want, and that keep us from getting what we do want)—all while honoring one of the cardinal rules of nudging: make it fun!

This Is Not Normal: The Politics of Everyday Expectations

by Cass R. Sunstein

How our shifting sense of "what's normal" defines the character of democracy

"A provocative examination of social constructs and those who would alternately undo or improve them."—Kirkus Reviews

This sharp and engaging book by leading governmental scholar Cass R. Sunstein examines dramatically shifting understandings of what’s normal—and how those shifts account for the feminist movement, the civil rights movement, the rise of Adolf Hitler, the founding itself, political correctness, the rise of gun rights, the response to COVID-19, and changing understandings of liberty. Prevailing norms include the principle of equal dignity, the idea of not treating the press as an enemy of the people, and the social unacceptability of open expressions of racial discrimination. But norms can turn upside-down in a hurry. What people tolerate, and what they abhor, depends on what else they are seeing. Exploring Nazism, #MeToo, the work of Alexander Hamilton and James Madison, constitutional amendments, pandemics, and the influence of Ayn Rand, Sunstein reveals how norms change, and ultimately determine the shape of society and government in the United States, Europe, and elsewhere.

The Second Bill Of Rights: FDR's UNfinished Revolution-- And Why We Need It More Than Ever

by Cass R. Sunstein

In 1944, Franklin Delano Roosevelt gave a State of the Union Address that was arguably the greatest political speech of the twentieth century. The speech began what Cass R. Sunstein calls the Second American Revolution by giving form and specificity, for the first time, to the concept of human economic rights. Many of the great legislative achievements of the past sixty years stem from Roosevelt's proposal for a Second Bill of Rights. Yet these rights have never been written into the Constitution, and they remain the subject of passionate debate. In recent years they have even lost ground.Using FDR's speech as a launching point, Sunstein examines the "legal realist" school of thought, which decisively refuted the idea of laissez-faire economics; describes how Roosevelt gradually developed the idea of a Second Bill of Rights; and asks why the Second Bill, which was almost enacted under the Warren Court, has never attained the constitutional status FDR sought for it. The reason, Sunstein maintains, is not anything unique to American culture or temperament but a particular historical accident: the election of Richard Nixon as President in 1968.This is an ambitious, sweeping book that argues for a new vision of FDR, of constitutional history, and of our current political scene. The Second Bill of Rights is an integral part of the American tradition and the starting point for contemporary political reform.

The Second Bill of Rights: FDR's Unfinished Revolution -- And Why We Need It More Than Ever

by Cass R. Sunstein

In 1944, Franklin Delano Roosevelt gave a State of the Union Address that was arguably the greatest political speech of the twentieth century. In it, Roosevelt grappled with the definition of security in a democracy, concluding that "unless there is security here at home, there cannot be lasting peace in the world." To help ensure that security, he proposed a "Second Bill of Rights" -- economic rights that he saw as necessary to political freedom. Many of the great legislative achievements of the past sixty years stem from Roosevelt's vision. Using this speech as a launching point, Cass R. Sunstein shows how these rights are vital to the continuing security of our nation. This is an ambitious, sweeping book that argues for a new vision of FDR, of constitutional history, and our current political scene.

Radicals in Robes: Why Extreme Right-Wing Courts Are Wrong for America

by Cass R. Sunstein

Most people think that the Supreme Court has a rough balance between left and right. This is a myth; in fact the justices once considered right-wing have now taken the mantle of the Court's moderates, and the liberal element has all but disappeared. Most people also think that judicial activism is solely a liberal movement. This is also a myth; since William Rehnquist was confirmed as Chief Justice in 1986, the Supreme Court has engaged in an unprecedented record of judicial activism. These two factors are feeding a movement to restore what many conservatives call "The Constitution in Exile," by which they mean the Constitution as it existed before the Roosevelt administration. Radicals in Robes explains what the restoration of this constitutional vision would mean. It would mean the end of the FCC, the SEC, the EPA, and every other federal agency that enacts regulations that have the force of law. It would mean that the clause of the First Amendment that says that Congress may make no law "respecting an establishment of religion" would be turned on its head. Marriage laws and many other familiar areas of modern life are all in the sights of this conservative movement. Radicals in Robes takes judicial philosophy out of the law schools and shows what it means when it intersects partisan politics. It pulls away the veil of rhetoric from a dangerous and radical right-wing movement and issues a strong and passionate warning about what conservatives really intend. One of the most respected legal theorists in the country, Cass R. Sunstein here issues a warning of compelling concern to us all.

Risk and Reason: Safety, Law, and the Environment

by Cass R. Sunstein

What should be done about airplane safety and terrorism, global warming, polluted water, nuclear power, and genetically engineered food? Decision-makers often respond to temporary fears, and the result is a situation of hysteria and neglect--and unnecessary illness and death. Risk and Reason explains the sources of these problems and explores what can be done about them. It shows how individual thinking and social interactions lead us in foolish directions. Offering sound proposals for social reform, it explains how a more sensible system of risk regulation, embodied in the idea of a "cost-benefit state," could save many thousands of lives and many billions of dollars too--and protect the environment in the process. Cass R. Sunstein is the Karl N. Llewellyn Distinguished Service Professor at the University of Chicago. Appointed by President Clinton to serve on the Advisory Committee on the Public Interest Obligations of Television Broadcasters. His many books include Republic.com (Princeton, 2001) and Designing Democracy (Oxford, 2001). He has worked in the United States Department of Justice and advised on law reform and constitution-making in many nations.

On Rumors: How Falsehoods Spread, Why We Believe Them, and What Can Be Done

by Cass R. Sunstein

Many of us are being misled. Claiming to know dark secrets about public officials, hidden causes of the current economic situation, and nefarious plans and plots, those who spread rumors know precisely what they are doing. And in the era of social media and the Internet, they know a lot about how to manipulate the mechanics of false rumors―social cascades, group polarization, and biased assimilation. They also know that the presumed correctives―publishing balanced information, issuing corrections, and trusting the marketplace of ideas―do not always work. All of us are vulnerable.

In On Rumors, Cass Sunstein uses examples from the real world and from behavioral studies to explain why certain rumors spread like wildfire, what their consequences are, and what we can do to avoid being misled. In a new afterword, he revisits his arguments in light of his time working in the Obama administration.

The NSA Report: Liberty and Security in a Changing World

by Cass R. Sunstein, Richard A. Clarke, Geoffrey R. Stone, The President's Review Group on Intelligence and Communications Technologies, Michael J. Morell, Peter Swire

The official report that has shaped the international debate about NSA surveillance

"We cannot discount the risk, in light of the lessons of our own history, that at some point in the future, high-level government officials will decide that this massive database of extraordinarily sensitive private information is there for the plucking. Americans must never make the mistake of wholly 'trusting' our public officials."―The NSA Report

This is the official report that is helping shape the international debate about the unprecedented surveillance activities of the National Security Agency. Commissioned by President Obama following disclosures by former NSA contractor Edward J. Snowden, and written by a preeminent group of intelligence and legal experts, the report examines the extent of NSA programs and calls for dozens of urgent and practical reforms. The result is a blueprint showing how the government can reaffirm its commitment to privacy and civil liberties―without compromising national security.

Why Societies Need Dissent (Oliver Wendell Holmes Lectures)

by Cass R. Sunstein

In this timely book, Cass R. Sunstein shows that organizations and nations are far more likely to prosper if they welcome dissent and promote openness. Attacking "political correctness" in all forms, Sunstein demonstrates that corporations, legislatures, even presidents are likely to blunder if they do not cultivate a culture of candor and disclosure. He shows that unjustified extremism, including violence and terrorism, often results from failure to tolerate dissenting views. The tragedy is that blunders and cruelties could be avoided if people spoke out.

Sunstein casts new light on freedom of speech, showing that a free society not only forbids censorship but also provides public spaces for dissenters to expose widely held myths and pervasive injustices. He provides evidence about the effects of conformity and dissent on the federal courts. The evidence shows not only that Republican appointees vote differently from Democratic appointees but also that both Republican and Democratic judges are likely to go to extremes if unchecked by opposing views. Understanding the need for dissent illuminates countless social debates, including those over affirmative action in higher education, because diversity is indispensable to learning.

Dissenters are often portrayed as selfish and disloyal, but Sunstein shows that those who reject pressures imposed by others perform valuable social functions, often at their own expense. This is true for dissenters in boardrooms, churches, unions, and academia. It is true for dissenters in the White House, Congress, and the Supreme Court. And it is true during times of war and peace.

How to Interpret the Constitution

by Cass R. Sunstein

From New York Times bestselling author Cass Sunstein, a timely and powerful argument for rethinking how the U.S. Constitution is interpreted

The U.S. Supreme Court has eliminated the right to abortion and is revisiting other fundamental questions today―about voting rights, affirmative action, gun laws, and much more. Once-arcane theories of constitutional interpretation are profoundly affecting the lives of all Americans. In this brief and urgent book, Harvard Law School professor Cass Sunstein provides a lively introduction to competing approaches to interpreting the Constitution―and argues that the only way to choose one is to ask whether it would change American life for the better or worse. If a method of interpretation would eliminate the right of privacy, allow racial segregation, or obliterate free speech, it would be unacceptable for that reason.

But some Supreme Court justices are committed to “originalism,” arguing that the meaning of the Constitution is settled by how it was publicly understood when it was ratified. Originalists insist that their approach is dictated by the Constitution. That, Sunstein argues, is a big mistake. The Constitution doesn’t contain instructions for its own interpretation. Any approach to constitutional interpretation needs to be defended in terms of its broad effects―what it does to our rights and our institutions. It must respect those rights and institutions―and safeguard the conditions for democracy itself.

Passionate and compelling, How to Interpret the Constitution is essential reading for anyone who is concerned about how the Supreme Court is changing the rights and lives of Americans today.

Despite intense interest in the subject, impeachment is widely misunderstood. Sunstein identifies and corrects a number of misconceptions. For example, he shows that the Constitution, not the House of Representatives, establishes grounds for impeachment, and that the president can be impeached for abuses of power that do not violate the law. Even neglect of duty counts among the “high crimes and misdemeanors” delineated in the republic’s foundational document. Sunstein describes how impeachment helps make sense of our constitutional order, particularly the framers’ controversial decision to install an empowered executive in a nation deeply fearful of kings.
With an eye toward the past and the future, Impeachment: A Citizen’s Guide considers a host of actual and imaginable arguments for a president’s removal, explaining why some cases are easy and others hard, why some arguments for impeachment have been judicious and others not.

Law and Leviathan: Redeeming the Administrative State

by Cass R. Sunstein, Adrian Vermeule

Winner of the 2021 Scribes Book Award

From two legal luminaries, a highly original framework for restoring confidence in a government bureaucracy increasingly derided as “the deep state.”

Is the modern administrative state illegitimate? Unconstitutional? Unaccountable? Dangerous? Intolerable? American public law has long been riven by a persistent, serious conflict, a kind of low-grade cold war, over these questions.

Cass Sunstein and Adrian Vermeule argue that the administrative state can be redeemed, as long as public officials are constrained by what they call the morality of administrative law. Law and Leviathan elaborates a number of principles that underlie this moral regime. Officials who respect that morality never fail to make rules in the first place. They ensure transparency, so that people are made aware of the rules with which they must comply. They never abuse retroactivity, so that people can rely on current rules, which are not under constant threat of change. They make rules that are understandable and avoid issuing rules that contradict each other.

These principles may seem simple, but they have a great deal of power. Already, without explicit enunciation, they limit the activities of administrative agencies every day. But we can aspire for better. In more robust form, these principles could address many of the concerns that have critics of the administrative state mourning what they see as the demise of the rule of law. The bureaucratic Leviathan may be an inescapable reality of complex modern democracies, but Sunstein and Vermeule show how we can at last make peace between those who accept its necessity and those who yearn for its downfall.

#Republic: Divided Democracy in the Age of Social Media

As the Internet grows more sophisticated, it is creating new threats to democracy. Social media companies such as Facebook can sort us ever more efficiently into groups of the like-minded, creating echo chambers that amplify our views. It's no accident that on some occasions, people of different political views cannot even understand each other. It's also no surprise that terrorist groups have been able to exploit social media to deadly effect.

Welcome to the age of #Republic.

In this revealing book, Cass Sunstein, the New York Times bestselling author of Nudge and The World According to Star Wars, shows how today's Internet is driving political fragmentation, polarization, and even extremism―and what can be done about it.

Thoroughly rethinking the critical relationship between democracy and the Internet, Sunstein describes how the online world creates "cybercascades," exploits "confirmation bias," and assists "polarization entrepreneurs." And he explains why online fragmentation endangers the shared conversations, experiences, and understandings that are the lifeblood of democracy.

In response, Sunstein proposes practical and legal changes to make the Internet friendlier to democratic deliberation. These changes would get us out of our information cocoons by increasing the frequency of unchosen, unplanned encounters and exposing us to people, places, things, and ideas that we would never have picked for our Twitter feed.

#Republic need not be an ironic term. As Sunstein shows, it can be a rallying cry for the kind of democracy that citizens of diverse societies most need.

On Freedom

by Timothy Snyder, Cass R. Sunstein

A Brilliant Exploration Of Freedom-what It Is, How It's Been Misunderstood, And Why It's Our Only Chance For Survival-by The Acclaimed Yale Historian And Author Of The #1 New York Times Bestseller On Tyranny-- Provided By Publisher.

On Freedom

by Timothy Snyder, Cass R. Sunstein

From New York Times bestselling author Cass Sunstein, a brisk, provocative book that shows what freedom really means―and requires―today

In this pathbreaking book, New York Times bestselling author Cass Sunstein asks us to rethink freedom. He shows that freedom of choice isn’t nearly enough. To be free, we must also be able to navigate life. People often need something like a GPS device to help them get where they want to go―whether the issue involves health, money, jobs, children, or relationships.

In both rich and poor countries, citizens often have no idea how to get to their desired destination. That is why they are unfree. People also face serious problems of self-control, as many of them make decisions today that can make their lives worse tomorrow. And in some cases, we would be just as happy with other choices, whether a different partner, career, or place to live―which raises the difficult question of which outcome best promotes our well-being.

Accessible and lively, and drawing on perspectives from the humanities, religion, and the arts, as well as social science and the law, On Freedom explores a crucial dimension of the human condition that philosophers and economists have long missed―and shows what it would take to make freedom real.

On Freedom

by Timothy Snyder, Cass R. Sunstein

A brilliant exploration of freedom—what it is, how it’s been misunderstood, and why it’s our only chance for survival—by the acclaimed Yale historian and author of the #1 New York Times bestseller On Tyranny

Timothy Snyder has been called “the leading interpreter of our dark times.” As a historian, he has given us startling reinterpretations of political collapse and mass killing. As a public intellectual, he has turned that knowledge toward counsel and prediction, working against authoritarianism here and abroad. His book On Tyranny has inspired millions around the world to fight for freedom. Now, in this tour de force of political philosophy, he helps us see exactly what we’re fighting for.

Freedom is the great American commitment, but as Snyder argues, we have lost sight of what it means—and this is leading us into crisis. Too many of us look at freedom as the absence of state power: We think we're free if we can do and say as we please, and protect ourselves from government overreach. But true freedom isn’t so much freedom from as freedom to—the freedom to thrive, to take risks for futures we choose by working together. Freedom is the value that makes all other values possible.

On Freedom takes us on a thrilling intellectual journey. Drawing on the work of philosophers and political dissidents, conversations with contemporary thinkers, and his own experiences coming of age in a time of American exceptionalism, Snyder identifies the practices and attitudes—the habits of mind—that will allow us to design a government in which we and future generations can flourish. We come to appreciate the importance of traditions (championed by the right) but also the role of institutions (the purview of the left). Intimate yet ambitious, this book helps forge a new consensus rooted in a politics of abundance, generosity, and grace.

Averting Catastrophe: Decision Theory for COVID-19, Climate Change, and Potential Disasters of All Kinds

by Cass R. Sunstein

Best-selling author Cass R. Sunstein examines how to avoid worst-case scenarios

The world is increasingly confronted with new challenges related to climate change, globalization, disease, and technology. Governments are faced with having to decide how much risk is worth taking, how much destruction and death can be tolerated, and how much money should be invested in the hopes of avoiding catastrophe. Lacking full information, should decision-makers focus on avoiding the most catastrophic outcomes? When should extreme measures be taken to prevent as much destruction as possible?

Averting Catastrophe explores how governments ought to make decisions in times of imminent disaster. Cass R. Sunstein argues that using the “maximin rule,” which calls for choosing the approach that eliminates the worst of the worst-case scenarios, may be necessary when public officials lack important information, and when the worst-case scenario is too disastrous to contemplate. He underscores this argument by emphasizing the reality of “Knightian uncertainty,” found in circumstances in which it is not possible to assign probabilities to various outcomes. Sunstein brings foundational issues in decision theory in close contact with real problems in regulation, law, and daily life, and considers other potential future risks. At once an approachable introduction to decision-theory and a provocative argument for how governments ought to handle risk, Averting Catastrophe offers a definitive path forward in a world rife with uncertainty.

Conformity: The Power of Social Influences

by Cass R. Sunstein

Bestselling author Cass R. Sunstein reveals the appeal and the danger of conformity

We live in an era of tribalism, polarization, and intense social division―separating people along lines of religion, political conviction, race, ethnicity, and sometimes gender. How did this happen? In Conformity, Cass R. Sunstein argues that the key to making sense of living in this fractured world lies in understanding the idea of conformity―what it is and how it works―as well as the countervailing force of dissent.

An understanding of conformity sheds new light on many issues confronting us today: the role of social media, the rise of fake news, the growth of authoritarianism, the success of Donald Trump, the functions of free speech, debates over immigration and the Supreme Court, and much more.

Lacking information of our own and seeking the good opinion of others, we often follow the crowd, but Sunstein shows that when individuals suppress their own instincts about what is true and what is right, it can lead to significant social harm. While dissenters tend to be seen as selfish individualists, dissent is actually an important means of correcting the natural human tendency toward conformity and has enormous social benefits in reducing extremism, encouraging critical thinking, and protecting freedom itself.

Sunstein concludes that while much of the time it is in the individual’s interest to follow the crowd, it is in the social interest for individuals to say and do what they think is best. A well-functioning democracy depends on it.

How to Become Famous: Lost Einsteins, Forgotten Superstars, and How the Beatles Came to Be

by Cass R. Sunstein

Fame is like lightning. Taylor Swift, Bob Dylan, Leonardo da Vinci, Jane Austen, Oprah Winfrey—all of them were struck. Why? What if they hadn't been?
Consider the most famous music group in history. What would the world be like if the Beatles never existed? This was the question posed by the playful, thought-provoking, 2019 film Yesterday, in which a young, completely unknown singer starts performing Beatles hits to a world that has never heard them. Would the Fab Four's songs be as phenomenally popular as they are in our own Beatle-infused world? The movie asserts that they would, but is that true? Was the success of the Beatles inevitable due to their amazing, matchless talent?
Maybe. It's hard to imagine our world without its stars, icons, and celebrities. They are part of our culture and history, seeming permanent and preordained. But as Harvard law professor (and passionate Beatles fan) Cass Sunstein shows in this startling book, that is far from the case. Focusing on both famous and forgotten (or simply overlooked) artists and luminaries in music, literature, business, science, politics, and other fields, he explores why some individuals become famous and others don't and offers a new understanding of the roles played by greatness, luck, and contingency in the achievement of fame.
Sunstein examines recent research on informational cascades, network effects, and group polarization to probe the question of how people become famous. He explores what ends up in the history books and in the literary canon and how that changes radically over time. He delves into the rich and entertaining stories of a diverse cast of famous characters, from John Keats, William Blake, and Jane Austen to Bob Dylan, Ayn Rand, and Stan Lee—as well as John, Paul, George, and Ringo.
How to Become Famous takes you on a fun, captivating, and at times profound journey that will forever change your perspective on the latest celebrity's "fifteen minutes of fame" and on what vaults some to the top—and leaves others in the dust.

Look Again: The Power of Noticing What Was Always There

by Cass R. Sunstein, Tali Sharot

This “smart and fun read, and a valuable way to revitalize your life” (Walter Isaacson) deftly explains how disrupting our well-worn routines, both good and bad, can rejuvenate and reset our brains for the better.

Have you ever noticed that what is exciting on Monday tends to become boring on Friday? Even passionate relationships, stimulating jobs, and breathtaking works of art lose their sparkle after a while. As easy as it is to stop noticing what is most wonderful in our lives, it’s also possible to stop noticing what is terrible. People get used to dirty air. They become unconcerned by their own misconduct, blind to inequality, and are more liable to believe misinformation than ever before.

Now, neuroscience professor Tali Sharot and Harvard law professor (and presidential advisor) Cass R. Sunstein investigate why we stop noticing both the great and not-so-great things around us and how to “dishabituate” at the office, in the bedroom, at the store, on social media, and in the voting booth.

This groundbreaking and “sensational guide to a more psychological rich life” (Angela Duckworth, New York Times bestselling author), based on decades of research, illuminates how we can reignite the sparks of joy, innovate, and recognize where improvements urgently need to be made. The key to this disruption—to seeing, feeling, and noticing again—is change. By temporarily changing your environment, changing the rules, changing the people you interact with—or even just stepping back and imagining change—you regain sensitivity, allowing you to identify more clearly the bad and more deeply appreciate the good.

Wiser: Getting Beyond Groupthink to Make Groups Smarter

by Cass R. Sunstein, Reid Hastie

Why are group decisions so hard?
Since the beginning of human history, people have made decisions in groups―first in families and villages, and now as part of companies, governments, school boards, religious organizations, or any one of countless other groups. And having more than one person to help decide is good because the group benefits from the collective knowledge of all of its members, and this results in better decisions. Right?
Back to reality. We’ve all been involved in group decisions―and they’re hard. And they often turn out badly. Why? Many blame bad decisions on “groupthink” without a clear idea of what that term really means.
Now, Nudge coauthor Cass Sunstein and leading decision-making scholar Reid Hastie shed light on the specifics of why and how group decisions go wrong―and offer tactics and lessons to help leaders avoid the pitfalls and reach better outcomes. In the first part of the book, they explain in clear and fascinating detail the distinct problems groups run into: They often amplify, rather than correct, individual errors in judgment They fall victim to cascade effects, as members follow what others say or do They become polarized, adopting more extreme positions than the ones they began with They emphasize what everybody knows instead of focusing on critical information that only a few people know
In the second part of the book, the authors turn to straightforward methods and advice for making groups smarter. These approaches include silencing the leader so that the views of other group members can surface, rethinking rewards and incentives to encourage people to reveal their own knowledge, thoughtfully assigning roles that are aligned with people’s unique strengths, and more.
With examples from a broad range of organizations―from Google to the CIA―and written in an engaging and witty style, Wiser will not only enlighten you; it will help your team and your organization make better decisions―decisions that lead to greater success.

Worst-Case Scenarios

by Cass R. Sunstein

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.

The Cost-Benefit Revolution

by Cass R. Sunstein

Why policies should be based on careful consideration of their costs and benefits rather than on intuition, popular opinion, interest groups, and anecdotes.

Opinions on government policies vary widely. Some people feel passionately about the child obesity epidemic and support government regulation of sugary drinks. Others argue that people should be able to eat and drink whatever they like. Some people are alarmed about climate change and favor aggressive government intervention. Others don't feel the need for any sort of climate regulation. In The Cost-Benefit Revolution, Cass Sunstein argues our major disagreements really involve facts, not values. It follows that government policy should not be based on public opinion, intuitions, or pressure from interest groups, but on numbers—meaning careful consideration of costs and benefits. Will a policy save one life, or one thousand lives? Will it impose costs on consumers, and if so, will the costs be high or negligible? Will it hurt workers and small businesses, and, if so, precisely how much?

As the Obama administration's “regulatory czar,” Sunstein knows his subject in both theory and practice. Drawing on behavioral economics and his well-known emphasis on “nudging,” he celebrates the cost-benefit revolution in policy making, tracing its defining moments in the Reagan, Clinton, and Obama administrations (and pondering its uncertain future in the Trump administration). He acknowledges that public officials often lack information about costs and benefits, and outlines state-of-the-art techniques for acquiring that information. Policies should make people's lives better. Quantitative cost-benefit analysis, Sunstein argues, is the best available method for making this happen—even if, in the future, new measures of human well-being, also explored in this book, may be better still.

How Change Happens (The MIT Press)

by Cass R. Sunstein

The different ways that social change happens, from unleashing to nudging to social cascades.
"Sunstein's book is illuminating because it puts norms at the center of how we think about change."—David Brooks, 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.

Punitive Damages: How Juries Decide

by Cass R. Sunstein, Reid Hastie, John W. Payne, David A. Schkade, W. Kip Viscusi

Over the past two decades, the United States has seen a dramatic increase in the number and magnitude of punitive damages verdicts rendered by juries in civil trials. Probably the most extraordinary example is the July 2000 award of $144.8 billion in the Florida class action lawsuit brought against cigarette manufacturers. Or consider two recent verdicts against the auto manufacturer BMW in Alabama. In identical cases, argued in the same court before the same judge, one jury awarded $4 million in punitive damages, while the other awarded no punitive damages at all. In cases involving accidents, civil rights, and the environment, multimillion-dollar punitive awards have been a subject of intense controversy.

But how do juries actually make decisions about punitive damages? To find out, the authors-experts in psychology, economics, and the law-present the results of controlled experiments with more than 600 mock juries involving the responses of more than 8,000 jury-eligible citizens. Although juries tended to agree in their moral judgments about the defendant's conduct, they rendered erratic and unpredictable dollar awards. The experiments also showed that instead of moderating juror verdicts, the process of jury deliberation produced a striking "severity shift" toward ever-higher awards. Jurors also tended to ignore instructions from the judges; were influenced by whatever amount the plaintiff happened to request; showed "hindsight bias," believing that what happened should have been foreseen; and penalized corporations that had based their decisions on careful cost-benefit analyses. While judges made many of the same errors, they performed better in some areas, suggesting that judges (or other specialists) may be better equipped than juries to decide punitive damages.

Using a wealth of new experimental data, and offering a host of provocative findings, this book documents a wide range of systematic biases in jury behavior. It will be indispensable for anyone interested not only in punitive damages, but also jury behavior, psychology, and how people think about punishment.

Animal Rights: Current Debates and New Directions

by Cass R. Sunstein, Martha C. Nussbaum

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 book offers a state-of-the-art treatment of that rethinking.

Law and Happiness

by Cass R. Sunstein, Eric A. Posner

Since the earliest days of philosophy, thinkers have debated the meaning of the term happiness and the nature of the good life. But it is only in recent years that the study of happiness—or “hedonics”—has developed into a formal field of inquiry, cutting across a broad range of disciplines and offering insights into a variety of crucial questions of law and public policy.

Law and Happinessbrings together the best and most influential thinkers in the field to explore the question of what makes up happiness—and what factors can be demonstrated to increase or decrease it. Martha Nussbaum offers an account of the way that hedonics can productively be applied to psychology, Cass R. Sunstein considers the unexpected relationship between happiness and health problems, Matthew Adler and Eric A. Posner view hedonics through the lens of cost-benefit analysis, David A. Weisbach considers the relationship between happiness and taxation, and Mark A. Cohen examines the role crime—and fear of crime—can play in people’s assessment of their happiness, and much more.

The result is a kaleidoscopic overview of this increasingly prominent field, offering surprising new perspectives and incisive analyses that will have profound implications on public policy.

Legal Reasoning and Political Conflict

by Cass R. Sunstein

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.

Going to Extremes: How Like Minds Unite and Divide

by Cass R. Sunstein

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."

Constitutional Personae: Heroes, Soldiers, Minimalists, and Mutes (Inalienable Rights)

by Cass R. Sunstein

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.

On Liberalism: In Defense of Freedom

by Cass R. Sunstein

A much-needed defense of liberalism—what it is, why it is under threat, and why we need it more than ever—from one of our most important political thinkers today.

More than at any time since World War II, liberalism is under pressure, even siege. On the right, some have given up on liberalism. They hold it responsible for the collapse of the family and traditional values, rampant criminality, disrespect for authority, and widespread immorality. On the left, some are turning their backs on liberalism. They think that it lacks the resources to handle the problems posed by entrenched inequalities, racism, sexism, corporate power, and environmental degradation. But those opposed to liberalism do not depict it accurately; they offer a caricature, and they neglect its history.

In On Liberalism, former advisor to Presidents Obama and Biden and New York Times–bestselling author Cass Sunstein offers a timely and clear understanding of liberalism—of its core commitments, of its breadth, of its internal debates, of its evolving character, of its promise—and why we need it more than ever. He also shows how and why liberalism has been, and should be, appealing to both the left and the right.

The book begins with a manifesto on behalf of liberalism, and then goes on to explore the central idea of “experiments of living,” to which a liberal constitutional order gives pride of place. From there, it discusses John Stuart Mill and Friedrich Hayek, defining liberal thinkers; the rule of law as liberals understand it; freedom of speech (including the place of lies and falsehoods within that freedom); free markets, economic liberty, and regulation; Franklin Delano Roosevelt’s Second Bill of Rights, with its social and economic guarantees; and finally, the concept of opportunity.

Never more urgently needed, On Liberalism moves the conversation well beyond the reductive and inflammatory political sound bites of our moment and advances a compelling argument on behalf of liberalism as the foundation of freedom and self-government.

Valuing Life: Humanizing the Regulatory State

by Cass R. Sunstein

The White House Office of Information and Regulatory Affairs (OIRA) is the United States’s regulatory overseer. In Valuing Life, Cass R. Sunstein draws on his firsthand experience as the Administrator of OIRA from 2009 to 2012 to argue that we can humanize regulation―and save lives in the process.

As OIRA Administrator, Sunstein helped oversee regulation in a broad variety of areas, including highway safety, health care, homeland security, immigration, energy, environmental protection, and education. This background allows him to describe OIRA and how it works―and how it can work better―from an on-the-ground perspective. Using real-world examples, many of them drawn from today’s headlines, Sunstein makes a compelling case for improving cost-benefit analysis, a longtime cornerstone of regulatory decision-making, and for taking account of variables that are hard to quantify, such as dignity and personal privacy. He also shows how regulatory decisions about health, safety, and life itself can benefit from taking into account behavioral and psychological research, including new findings about what scares us, and what does not. By better accounting for people’s fallibility, Sunstein argues, we can create regulation that is simultaneously more human and more likely to achieve its goals.

In this highly readable synthesis of insights from law, policy, economics, and psychology, Sunstein breaks down the intricacies of the regulatory system and offers a new way of thinking about regulation that incorporates human dignity– and an insistent focus on the consequences of our choices.

Is Multiculturalism Bad for Women?

by Cass R. Sunstein, Sander L. Gilman, Saskia Sassen, Joseph Raz, Susan Moller Okin, Azizah Y. Al-Hibri, Yael Tamis

Polygamy, forced marriage, female genital mutilation, punishing women for being raped, differential access for men and women to health care and education, unequal rights of ownership, assembly, and political participation, unequal vulnerability to violence. These practices and conditions are standard in some parts of the world. Do demands for multiculturalism--and certain minority group rights in particular--make them more likely to continue and to spread to liberal democracies? Are there fundamental conflicts between our commitment to gender equity and our increasing desire to respect the customs of minority cultures or religions? In this book, the eminent feminist Susan Moller Okin and fifteen of the world's leading thinkers about feminism and multiculturalism explore these unsettling questions in a provocative, passionate, and illuminating debate.

Okin opens by arguing that some group rights can, in fact, endanger women. She points, for example, to the French government's giving thousands of male immigrants special permission to bring multiple wives into the country, despite French laws against polygamy and the wives' own bitter opposition to the practice. Okin argues that if we agree that women should not be disadvantaged because of their sex, we should not accept group rights that permit oppressive practices on the grounds that they are fundamental to minority cultures whose existence may otherwise be threatened.

In reply, some respondents reject Okin's position outright, contending that her views are rooted in a moral universalism that is blind to cultural difference. Others quarrel with Okin's focus on gender, or argue that we should be careful about which group rights we permit, but not reject the category of group rights altogether. Okin concludes with a rebuttal, clarifying, adjusting, and extending her original position. These incisive and accessible essays--expanded from their original publication in Boston Review and including four new contributions--are indispensable reading for anyone interested in one of the most contentious social and political issues today.

The diverse contributors, in addition to Okin, are Azizah al-Hibri, Abdullahi An-Na'im, Homi Bhabha, Sander Gilman, Janet Halley, Bonnie Honig, Will Kymlicka, Martha Nussbaum, Bhikhu Parekh, Katha Pollitt, Robert Post, Joseph Raz, Saskia Sassen, Cass Sunstein, and Yael Tamir.

Laws of Fear: Beyond the Precautionary Principle (The Seeley Lectures, Series Number 6)

by Cass R. Sunstein

This book is about the complex relationship between fear, danger, and the law. Cass Sunstein argues that the precautionary principle is incoherent and potentially paralyzing, as risks exist on all sides of social situations and there is no 'general' precautionary principle as such. His insight into The Laws of Fear represents a major statement for the contemporary world from one of the most influential political and legal theorists writing today.

Simpler: The Future of Government

by Cass R. Sunstein

Governments everywhere are undergoing a quiet and profound revolution: they’re getting simpler, more cost-effective, and focused on improved outcomes not politics. For four years one of the leading lights of that revolution, Cass Sunstein, as President Obama’s “Regulatory Czar,” oversaw the brilliant and successful effort to give every American better government. In “a remarkably fun, engaging read” (Fortune.com), he explains how, why, and what should come next.

For Americans, the future of government arrived in 2009. Government became simpler, it became smarter. It worked better. Cass Sunstein, America’s “regulatory czar” under President Barack Obama, was at the center of it all. Drawing on state-of-the-art work in behavioral psychology and economics, Sunstein helped save the country more than $91 billion and an unknown number of lives. This was accomplished through the extraordinary power of nudges—seemingly modest policies that preserve freedom of choice, better lives, and fundamentally improve government. In combination with cost-benefit analysis, nudges are already saving money, saving lives, and improving, by simplifying, government. In Simpler,Sunstein speaks for the first time about what he encountered and accomplished in the Obama Administration and what the lessons are for everyone going forward.

We don’t need big government or small government; we need better government. Simpler is a “lucid, engaging treatment of behavioral economics that sees a role for the state in nudging humans towards rationality and responsibility. The result is a forthright, compelling vision of technocratic government that’s both efficient and humane” (Publishers Weekly, starred review). And it just may be “the most important book to come out of President Obama’s first term” (Walter Isaacson).

A Constitution of Many Minds: Why the Founding Document Doesn't Mean What It Meant Before

by Cass R. Sunstein

The future of the U.S. Supreme Court hangs in the balance like never before. Will conservatives or liberals succeed in remaking the court in their own image? In A Constitution of Many Minds, acclaimed law scholar Cass Sunstein proposes a bold new way of interpreting the Constitution, one that respects the Constitution's text and history but also refuses to view the document as frozen in time.

Exploring hot-button issues ranging from presidential power to same-sex relations to gun rights, Sunstein shows how the meaning of the Constitution is reestablished in every generation as new social commitments and ideas compel us to reassess our fundamental beliefs. He focuses on three approaches to the Constitution--traditionalism, which grounds the document's meaning in long-standing social practices, not necessarily in the views of the founding generation; populism, which insists that judges should respect contemporary public opinion; and cosmopolitanism, which looks at how foreign courts address constitutional questions, and which suggests that the meaning of the Constitution turns on what other nations do.

Sunstein demonstrates that in all three contexts a "many minds" argument is at work--put simply, better decisions result when many points of view are considered. He makes sense of the intense debates surrounding these approaches, revealing their strengths and weaknesses, and sketches the contexts in which each provides a legitimate basis for interpreting the Constitution today.

This book illuminates the underpinnings of constitutionalism itself, and shows that ours is indeed a Constitution, not of any particular generation, but of many minds.

One Case at a Time: Judicial Minimalism on the Supreme Court

by Cass R. Sunstein

Abortion, affirmative action, the "right to die," pornography and free speech, homosexuality and sex discrimination: as eagerly as the Supreme Court's rulings on these hot issues are awaited and as intently as they're studied, they never seem to settle anything once and for all. But something is settled in the process--in the incremental approach--as Cass Sunstein shows us in this instructive book.

One of America's preeminent constitutional scholars, Sunstein mounts a defense of the most striking characteristic of modern constitutional law: the inclination to decide one case at a time. Examining various controversies, he shows how--and why--the Court has avoided broad rulings on issues from the legitimacy of affirmative action to the "right to die," and in doing so has fostered rather than foreclosed public debate on these difficult topics. He offers an original perspective on the right of free speech and the many novel questions raised by Congress's efforts to regulate violent and sexual materials on new media such as the Internet and cable television. And on the relationship between the Constitution and homosexuality and sex discrimination, he reveals how the Court has tried to ensure against second-class citizenship--and the public expression of contempt for anyone--while leaving a degree of flexibility to the political process.

One Case at a Time also lays out, and celebrates, the remarkable constellation of rights--involving both liberty and equality--that now commands a consensus in American law. An authoritative guide to the Supreme Court, the book offers a new understanding of the American Constitution, and of the relationship between democracy and constitutionalism, and between rights and self-government.

The Partial Constitution

by Cass R. Sunstein

American constitutional law is at a crossroads. In a major new interpretation of the Constitution, Cass Sunstein offers a clear account of our present dilemmas and shows where we might go from here.

As it is currently interpreted, the Constitution is partial, Sunstein asserts. It is, first of all, biased. Contemporary constitutional law treats the status quo as neutral and just, and any departure as necessarily partisan. But when the status quo is neither neutral nor just, Sunstein argues, reasoning of this sort produces injustice. The Constitution is also partial in another sense: its meaning has come to be identified solely with the decisions of the Supreme Court. This was not always the case, as Sunstein demonstrates; nor was it the intention of the country's founders. Instead, the Constitution often served as a catalyst for public deliberation about its general terms and aspirations--and Sunstein makes a strong case for reviving this broader understanding of the Constitution's role.

In light of this analysis, Sunstein proposes solutions to some of the most hotly disputed issues of our time, including affirmative action, sex discrimination, pornography, "hate speech," and government funding of religious schools and the arts. In an especially striking argument, he claims that theequal protection clause of the Fourteenth Amendment--not the right to privacy--protects a woman's right to choose abortion. Sunstein connects these and other debates to the Constitution's historic commitment to public deliberation among political equalsand in doing so, he reconceives many of our most basic constitutional rights, such as free speech and equality under law. He urges that public deliberation about the meaning of the Constitution in turn be freed from a principle of neutrality based on the status quo. His work points to a historically sound but fundamentally new understanding of the American constitutional process as an exercise in deliberative democracy.

Why Nudge?: The Politics of Libertarian Paternalism (The Storrs Lectures Series)

by Cass R. Sunstein

The bestselling author of Simpler offers a powerful, provocative, and convincing argument for protecting people from their own mistakes

Based on a series of pathbreaking lectures given at Yale University in 2012, this powerful, thought-provoking work by national best-selling author Cass R. Sunstein combines legal theory with behavioral economics to make a fresh argument about the legitimate scope of government, bearing on obesity, smoking, distracted driving, health care, food safety, and other highly volatile, high-profile public issues. Behavioral economists have established that people often make decisions that run counter to their best interests—producing what Sunstein describes as “behavioral market failures.” Sometimes we disregard the long term; sometimes we are unrealistically optimistic; sometimes we do not see what is in front of us. With this evidence in mind, Sunstein argues for a new form of paternalism, one that protects people against serious errors but also recognizes the risk of government overreaching and usually preserves freedom of choice.

Against those who reject paternalism of any kind, Sunstein shows that “choice architecture”—government-imposed structures that affect our choices—is inevitable, and hence that a form of paternalism cannot be avoided. He urges that there are profoundly moral reasons to ensure that choice architecture is helpful rather than harmful—and that it makes people’s lives better and longer.

Republic.com 2.0

by Cass R. Sunstein

What happens to democracy and free speech if people use the Internet to listen and speak only to the like-minded? What is the benefit of the Internet's unlimited choices if citizens narrowly filter the information they receive? Cass Sunstein first asked these questions in 2001's Republic.com. Now, in Republic.com 2.0, Sunstein thoroughly rethinks the critical relationship between democracy and the Internet in a world where partisan Weblogs have emerged as a significant political force.

Republic.com 2.0 highlights new research on how people are using the Internet, especially the blogosphere. Sunstein warns against "information cocoons" and "echo chambers," wherein people avoid the news and opinions that they don't want to hear. He also demonstrates the need to regulate the innumerable choices made possible by technology. His proposed remedies and reforms emphasize what consumers and producers can do to help avoid the perils, and realize the promise, of the Internet.

Radicals in Robes

by Cass R. Sunstein

Most people think that the Supreme Court has a rough balance between left and right. This is a myth; in fact the justices once considered right-wing have now taken the mantle of the Court's moderates, and the liberal element has all but disappeared. Most people also think that judicial activism is solely a liberal movement. This is also a myth; since William Rehnquist was confirmed as Chief Justice in 1986, the Supreme Court has engaged in an unprecedented record of judicial activism. These two factors are feeding a movement to restore what many conservatives call "The Constitution in Exile," by which they mean the Constitution as it existed before the Roosevelt administration. Radicals in Robes explains what the restoration of this constitutional vision would mean. It would mean the end of the FCC, the SEC, the EPA, and every other federal agency that enacts regulations that have the force of law. It would mean that the clause of the First Amendment that says that Congress may make no law "respecting an establishment of religion" would be turned on its head. Marriage laws and many other familiar areas of modern life are all in the sights of this conservative movement. Radicals in Robes takes judicial philosophy out of the law schools and shows what it means when it intersects partisan politics. It pulls away the veil of rhetoric from a dangerous and radical right-wing movement and issues a strong and passionate warning about what conservatives really intend. One of the most respected legal theorists in the country, Cass R. Sunstein here issues a warning of compelling concern to us all.

The Ethics of Influence: Government in the Age of Behavioral Science (Cambridge Studies in Economics, Choice, and Society)

by Cass R. Sunstein

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 (2008), 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.

Infotopia: How Many Minds Produce Knowledge

by Cass R. Sunstein

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.

Conspiracy Theories and Other Dangerous Ideas

by Cass R. Sunstein

The most controversial essays from the bestselling author once called the most dangerous man in America—collected for the first time.

The nation’s most-cited legal scholar who for decades has been at the forefront of applied behavioral economics, and the bestselling author of Nudge and Simpler, Cass Sunstein is one of the world’s most innovative thinkers in the academy and the world of practical politics. In the years leading up to his confirmation as the administrator of the White House Office of Information and Regulatory Affairs (OIRA), Sunstein published hundreds of articles on everything from same-sex marriage to cost-benefit analysis. Conspiracy Theories and Other Dangerous Ideas is a collection of his most famous, insightful, relevant, and inflammatory pieces. Within these pages you will learn:

• Why perfectly rational people sometimes believe crazy conspiracy theories
• What wealthy countries should and should not do about climate change
• Why governments should allow same-sex marriage, and what the “right to marry” is all about
• Why animals have rights (and what that means)
• Why we “misfear,” meaning get scared when we should be unconcerned and are unconcerned when we should get scared
• What kinds of losses make us miserable, and what kinds of losses are absolutely fine
• How to find the balance between religious freedom and gender equality
• And much more . . .

Cass Sunstein is a unique, controversial, and exciting voice in the political world. A man who cuts through the fog of left vs. right arguments and offers logical, evidence-based, and often surprising solutions to today’s most challenging questions.

Choosing Not to Choose: Understanding the Value of Choice

by Cass R. Sunstein

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.

After the Rights Revolution: Reconceiving the Regulatory State

by Cass R. Sunstein

In the twentieth century, American society has experienced a “rights revolution”: a commitment by the national government to promote a healthful environment, safe products, freedom from discrimination, and other rights unknown to the founding generation. This development has profoundly affected constitutional democracy by skewing the original understanding of checks and balances, federalism, and individual rights. Cass Sunstein tells us how it is possible to interpret and reform this regulatory state regime in a way that will enhance freedom and welfare while remaining faithful to constitutional commitments.

Sunstein vigorously defends government regulation against Reaganite/Thatcherite attacks based on free-market economics and pre–New Deal principles of private right. Focusing on the important interests in clean air and water, a safe workplace, access to the air waves, and protection against discrimination, he shows that regulatory initiatives have proved far superior to an approach that relies solely on private enterprise. Sunstein grants that some regulatory regimes have failed and calls for reforms that would amount to an American perestroika: a restructuring that embraces the use of government to further democratic goals but that insists on the decentralization and productive potential of private markets.

Sunstein also proposes a theory of interpretation that courts and administrative agencies could use to secure constitutional goals and to improve the operation of regulatory programs. From this theory he seeks to develop a set of principles that would synthesize the modern regulatory state with the basic premises of the American constitutional system. Teachers of law, policymakers and political scientists, economists and historians, and a general audience interested in rights, regulation, and government will find this book an essential addition to their libraries.

Separation of Powers

by Cass R. Sunstein

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.

Manipulation What It Is, Why It's Bad, What to Do About It

by Cass R. Sunstein

New technologies are offering companies, politicians, and others unprecedented opportunity to manipulate us. Sometimes we are given the illusion of power - of freedom - through choice, yet the game is rigged, pushing us in specific directions that lead to less wealth, worse health, and weaker democracy. In, Manipulation, nudge theory pioneer and New York Times bestselling author, Cass Sunstein, offers a new definition of manipulation for the digital age, explains why it is wrong; and shows what we can do about it. He reveals how manipulation compromises freedom and personal agency, while threatening to reduce our well-being; he explains the difference between manipulation and unobjectionable forms of influence, including 'nudges'; and he lifts the lid on online manipulation and manipulation by artificial intelligence, algorithms, and generative AI, as well as threats posed by deepfakes, social media, and 'dark patterns,' which can trick people into giving up time and money. Drawing on decades of groundbreaking research in behavioral science, this landmark book outlines steps we can take to counteract manipulation in our daily lives and offers guidance to protect consumers, investors, and workers.

On Liberalism - In Defense of Freedom

by Cass R. Sunstein

A much-needed defense of liberalism—what it is, why it is under threat, and why we need it more than ever—from one of our most important political thinkers today.

More than at any time since World War II, liberalism is under pressure, even siege. On the right, some have given up on liberalism. They hold it responsible for the collapse of the family and traditional values, rampant criminality, disrespect for authority, and widespread immorality. On the left, some are turning their backs on liberalism. They think that it lacks the resources to handle the problems posed by entrenched inequalities, racism, sexism, corporate power, and environmental degradation. But those opposed to liberalism do not depict it accurately; they offer a caricature, and they neglect its history.

In On Liberalism, former advisor to Presidents Obama and Biden and New York Times–bestselling author Cass Sunstein offers a timely and clear understanding of liberalism—of its core commitments, of its breadth, of its internal debates, of its evolving character, of its promise—and why we need it more than ever. He also shows how and why liberalism has been, and should be, appealing to both the left and the right.

The book begins with a manifesto on behalf of liberalism, and then goes on to explore the central idea of “experiments of living,” to which a liberal constitutional order gives pride of place. From there, it discusses John Stuart Mill and Friedrich Hayek, defining liberal thinkers; the rule of law as liberals understand it; freedom of speech (including the place of lies and falsehoods within that freedom); free markets, economic liberty, and regulation; Franklin Delano Roosevelt’s Second Bill of Rights, with its social and economic guarantees; and finally, the concept of opportunity.

Never more urgently needed, On Liberalism moves the conversation well beyond the reductive and inflammatory political sound bites of our moment and advances a compelling argument on behalf of liberalism as the foundation of freedom and self-government.
