NEW YORK TIMES BESTSELLER

#1 Washington Post Bestseller 

There’s Santa Claus, Shakespeare, Mickey Mouse, the Bible, and then there’s Star Wars. Nothing quite compares to sitting down with a young child and hearing the sound of John Williams’s score as those beloved golden letters fill the screen. In this fun, erudite, and often moving book, Cass R. Sunstein explores the lessons of Star Wars as they relate to childhood, fathers, the Dark Side, rebellion, and redemption. As it turns out, Star Wars also has a lot to teach us about constitutional law, economics, and political uprisings.

In rich detail, Sunstein tells the story of the films’ wildly unanticipated success and explores why some things succeed while others fail. Ultimately, Sunstein argues, Star Wars is about freedom of choice and our never-ending ability to make the right decision when the chips are down. Written with buoyant prose and considerable heart, The World According to Star Wars shines a bright new light on the most beloved story of our time.

From the New York Times bestselling author of Nudge and The World According to Star Wars, a revealing account of how today's Internet threatens democracy—and what can be done about it

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 one another. 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, New York Times bestselling author Cass Sunstein shows how today’s Internet is driving political fragmentation, polarization, and even extremism--and what can be done about it. He proposes practical and legal changes to make the Internet friendlier to democratic deliberation, showing that #Republic need not be an ironic term. Rather, it can be a rallying cry for the kind of democracy that citizens of diverse societies need most.

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.

"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.

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.
