"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. "--

"Why does a disease that killed only a handful of Americans like ebola provoke panic, but the flu-which kills tens of thousands each year-is dismissed with a yawn? Why is an unarmed young black woman who knocks on a stranger's front door to ask for help after her car breaks down perceived to be so threatening that the stranger shoots her dead? In Jumping at Shadows, Sasha Abramsky sets his sights on America's most dangerous epidemic: irrational fear. In this meditation on the paralyzing terror Americans feel when confronted with something they don't understand-from foreigners to tropical viruses to universal health care-Abramsky delivers an eye-opening analysis of our misconceptions about risk and threats, and how our brains interpret them, both at a neurological level and at a conscious one. What emerges is a journey through a political and cultural landscape that is defined by our fears, which are often misplaced. Ultimately, Abramsky shows that our fears can teach us a great deal about our society, exposing our deeply ingrained racism, classism, xenophobia, and susceptibility to the toxic messages of demagogues"--
