From the world-leaders in strategic thinking and the multi-million copy bestselling authors of Thinking Fast and Slow and Nudge, the next big book to change the way you think.

We like to think we make decisions based on good reasoning – and that our doctors, judges, politicians, economic forecasters and employers do too. In this groundbreaking book, three world-leading behavioural scientists come together to assess the last great fault in our collective decision-making: noise.

We all make bad judgements more than we think. Noise shows us what we can do to make better ones.

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.

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.

#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.

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.

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.

"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.
