Authors@Google: Phillip Zimbardo

What makes good people do bad things? How can moral people be seduced to act immorally? Where is the line separating good from evil, and who is in danger of crossing it? Renow-ned social psychologist Philip Zimbardo has the answers, and in The Lucifer Effect he 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 trailblazing research, Zimbardo details how situational forces and group dynamics can work in concert to make monsters out of decent men and women.

Zimbardo, professor emeritus of psychology at Stanford University, is perhaps best known as the creator of the Stanford Prison Experiment. For the first time, he tells the full story of this landmark study, in which a group of college-student volunteers was randomly divided into "guards" and "inmates" and then placed in a mock prison environment. Within a week the study was abandoned, as ordinary college students were transformed into either brutal, sadistic guards or emotionally broken prisoners.
