"The different ways that social change happens, from unleashing to nudging to social cascades. "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."

In this book, Amitai Etzioni, public intellectual and leading proponent of communitarian values, defends the view that no society can flourish without a shared obligation to "the common good." Rejecting claims made by some liberal thinkers that it is not possible to balance individual rights with uncoerced civic responsibility, Etzioni explores a number of key issues which pose important questions for those concerned with promoting the common good in contemporary society. Are we morally obliged to do more for our communities beyond treating everyone as endowed with basic rights? Should privacy be regarded not merely as a right but also as an obligation? And should the right to free speech take priority over the need to protect children from harmful material in the media and on the internet? and public safety in an age of global terrorism. He evaluates various new government devices, from wiretaps to viruses, which open our lives to public scrutiny. Particular attention is given to the issues surrounding government-issued DNA tests. The book concludes by questioning whether we can still talk of a relationship between the common good and the nation-state, or whether the "online" society in which we live will make it increasingly difficult to maintain those communities which are the very homeland of the common good. will be important reading for students and scholars of political science, social philosophy, sociology, and public policy, as well as for the interested general reader.
