Here, for the first time and in detail, 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 emotion
