Wired has a 3 minute video with previously unseen photos from Abu Ghraib. The piece includes an interview with a research psychologist, Philip Zimbardo, who studies how regular people become capable of committing acts of torture and prisoner abuse.
Zimbardo conducted a now-famous experiment at Stanford University in 1971, involving students who posed as prisoners and guards. Five days into the experiment, Zimbardo halted the study when the student guards began abusing the prisoners, forcing them to strip naked and simulate sex acts.
His book, The Lucifer Effect: Understanding How Good People Turn Evil, explores how a “perfect storm” of conditions can make ordinary people commit horrendous acts.
He spoke with Wired.com about what Abu Ghraib and his prison study can teach us about evil and why heroes are, by nature, social deviants.
