What happens to democracy and free speech if people use the Internet to create echo chambers--to listen and speak only to the like-minded? What is the democratic benefit of the Internet's unlimited choices if citizens narrowly limit the information they receive, creating ever-smaller niches and fragmenting the shared public conversation on which democracy depends? Cass Sunstein first asked these questions before 9/11, in Republic.com, and they have become even more urgent in the years since. Now, in Republic.com 2.0, Sunstein thoroughly rethinks the critical relationship between democracy and the Internet in a world where partisan Web logs have emerged as a significant force in politics and where cyber-jihadists have embraced the Internet to thwart democracy and spread violence. Emphasizing the value of unplanned, unchosen encounters, the original Republic.com provoked a strong reaction from cyber-optimists. In Republic.com 2.0 Sunstein answers the critics and expands his argument to take account of new developments, including the blogosphere, and fresh evidence about how people are using the Internet. He demonstrates that the real question is how to avoid "information cocoons" and to ensure that the unrestricted choices made possible by technology do not undermine democracy. Sunstein also proposes new remedies and reforms--focusing far less on what government should do, and much more on what consumers and producers should do--to help democracy avoid the perils, and realize the promise, of the Internet.

"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. "--

"In modern nations, political disagreement is the source of both the gravest danger and the greatest security," writes Cass Sunstein. All democracies face intense political conflict. But is this conflict necessarily something to fear? In this provocative book, one of our leading political and legal theorists reveals how a nation's divisions of conviction and belief can be used to safeguard democracy.Confronting one explosive political issue after another, from presidential impeachment to the limits of religious liberty, from discrimination against women and gays to the role of the judiciary, Sunstein constructs a powerful new perspective from which to show how democracies negotiate their most divisive real-world problems. He focuses on a series of concrete concerns that go to the heart of the relationship between the idea of democracy and the idea of constitutionalism. Illustrating his discussion with examples from constitutional debates and court-cases in South Africa, Eastern Europe, Israel, America, and elsewhere, Sunstein takes readers through a number of highly charged questions: When should government be permitted to control discriminatory behavior by or within religious organizations? Does it make sense to govern on the basis of popular referenda? Can the right to have an abortion be defended? Can we defend Internet regulation? Should the law step in if children are being schooled in discriminatory preferences and beliefs? Should a constitution protect rights to food, shelter, and health care?Disputes over questions such as these can be fierce enough to pose a grave threat. But in a paradox whose elaboration forms the core of Sunstein's book, it is a nation's apparently threatening diversity of opinion that can ensure its integrity.Extending his important recent work on the way deliberation within like-minded groups can produce extremism, Sunstein breaks new ground in identifying the mechanisms behind political conflict in democratic nations. At the same time, he develops a profound understanding of a constitutional democracy's system of checks and balances. Sunstein shows how a good constitution, fostering a "republic of reasons," enables people of opposing ethical and religious commitments to reach agreement where agreement is necessary, while making it unnecessary to reach agreement when agreement is impossible.A marvel of lucid, subtle reasoning, DESIGNING DEMOCRACY makes invaluable reading for anyone concerned with the promises and pitfalls of the democratic experiment.
