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 unearths fascinating and surprising revelations ... Perhaps the most profound insight from Sunstein’s book is the realization that conformity is working on us pretty much all the time. We think we choose what movies to watch, what books to read, or even what political tribe to claim—but our ability to form our own opinion on anything is greatly influenced by imperceptible forces nudging us towards consensus. That’s not always a bad thing. But, as Sunstein himself writes, ‘For all the good conformity does, it can also crush what is most precious and most vital in the human soul.’" - GQ

"Points out the positive benefits of conformity while also exploring how following the crowd can easily take individuals down paths of extreme thinking. Drawing on scientific studies, Sunstein discusses the corrective effects of dissent for the common good and not simply out of contrarianism. Eminently relevant, Sunstein's clarifying discussion is a must-read." - Booklist

"Sunstein masterfully synthesizes decades of research into a coherent narrative and provides actionable ideas that can be used by a wide range of organizations. The book is another one of Sunstein’s that I expect to see in the hands of academics, policymakers, and businesspeople alike in the airport or local coffee shop." - Political Science Quarterly

"This book stands out from Sunstein’s other books in its focus on the broad societal implications of social influence. Sunstein grounds his argument in the principles underlying American democracy, and in doing so, he makes it difficult not to become depressed at how distant our current state of affairs seems from that ideal. However, Sunstein offers optimism in the form of a framework for actionable solutions." - Political Science Quarterly
