The Lucifer effect

What makes good people do bad things? Where is the line separating good from evil, and who is in danger of crossing it? Social psychologist Philip Zimbardo explains how--and the myriad reasons why--we are all susceptible to the lure of "the dark side." Drawing on examples from history as well as his own research, Zimbardo details how situational forces and group dynamics can work in concert to make monsters out of decent people. By illuminating the psychological causes behind such disturbing metamorphoses, Zimbardo enables us to better understand a variety of phenomena, from corporate malfeasance to organized genocide. He replaces the long-held notion of the "bad apple" with that of the "bad barrel"--the idea that the social setting and the system contaminate the individual, rather than the other way around. Yet we are capable of resisting evil, he argues, and can even teach ourselves to act heroically.--From publisher description.
