Many of us are being misled. Claiming to know the “pals” of presidential aspirants, dark secrets about public officials, and hidden causes of the current economic crisis, those who spread rumors know precisely what they are doing. They are sometimes able to derail political candidates, injure companies and reputations, even damage democratic governance. And in the era of the Internet, they know more about manipulating the mechanics of false rumors—social cascades, group polarization, and biased assimilation—than you do. They also know that the presumed correctives—publishing balanced information, issuing corrections, and trusting to the marketplace of ideas—do not always work. A pioneer in the effort “to design regulation around the ways people behave” ( The Wall Street Journal ), Cass R. Sunstein uses examples from the real world and from behavioral studies to explain why certain rumors spread like wildfire and what we can do to avoid being misled.

Gossip is no trivial matter; despite its reputation, Epstein argues, it is an eternal and necessary human enterprise. Proving that he himself is a master of the art, Epstein serves up delightful mini-biographies of the Great Gossips of the Western World, along with many choice bits from his own experience. He also makes a powerful case that gossip has morphed from its old-fashioned best--clever, mocking, a great private pleasure--to a corrosive new-school version, thanks to the reach of the mass media and the Internet. Written in his trademark erudite and witty style, Gossip captures the complexity of this immensely entertaining subject.

When we think of family, we most often think of our sisters and brothers, our cousins and grandparents, rather than our world family or even our community connections. We still identify with our differences more than our similarities, unless it's convenient to do otherwise. Here, two seasoned authors tackle the question of family and what it means to us now and how it might change to help us address the problems that affect us all. Using specific examples throughout the work, they present a unique approach to what it means to belong to one human family. Beginning with a consideration of how the family unit has begun to be defined by allegiances, by common ties and empathy, the authors then discuss the evolution of the family unit and how the "us" vs. "them" mentality gave way to a way of life that separated peoples rather than brought them together. They consider family values, how they arose, developed, were perverted or perfected to suit the family unit's needs, and the confusion that followed. Humanity on a Tightrope focuses on what families and family values are, and how they often create an "us versus them" mentality that is at the root of many of today's most crucial problems from terrorism, racism, and war to the failure of humanity to come to grips with potentially lethal global environmental problems. The book underlines a basic element for solving the human predicament - quickly spreading the domain of empathy. It takes a close look at how we can do that, building on the findings of both social and natural science and using tools ranging from brain imaging to the internet. It explains how civilization is unlikely to persist unless many more people learn to put themselves in the shoes of others to keep society balancing on the tightrope to sustainability - a tightrope suspended over the collapse of civilization.
