#Republic: Divided Democracy in the Age of Social Media — By Cass R. Sunstein

"I . . . found myself shocked at how relevant Sunstein’s account was to my own life and the ways I seek out and encounter information, which is in a way the value of the book--it gets you to reflect on the role of your information habits on your view of the world around you. And if you want to know how important that is, well, you should read Sunstein's book."

Annie Coreno, Publishers Weekly (staff pick)

"Required reading for anyone who is concerned with the future of democracy."

—The Economist

"Ripped straight from the headlines, but informed by hard data, #Republic should command the attention of American citizens across the political spectrum."

Glenn C. Altschuler, Philadelphia Inquirer

"America's leading legal academic gives us a way to address democracy's leading challenge--preserving a public informed enough to govern itself. Drawing on an incredible range of scholarship and experience, this book could not be more timely. Or urgently needed."

— Lawrence Lessig, Harvard Law School

"What went wrong with social media and also with democracy? Here's the guy who saw it coming, and yes he does have all the answers."

—Tyler Cowen, author of The Great Stagnation

As the Internet grows more sophisticated, it is driving political fragmentation, polarization, and even extremism, creating new threats to democracy.

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

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.

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.
