This vintage stunt from a 1962 episode of Candid Camera makes for a good laugh. But it also captures something important about human psychology -- something that social psychologist Philip Zimbardo, famous for his Stanford Prison Experiment, describes on a website related to his 2007 book The Lucifer Effect: Understanding How Good People Turn Evil. He writes:
One of the most popular scenarios in the long history of Alan Funt's ingenious Candid Camera programs is "Face The Rear." An elevator is rigged so that after an unsuspecting person enters, four Candid Camera staff enter, and one by one they all face the rear. The doors close and then reopen; now revealing that the passenger had conformed and is now also facing the rear. Doors close and reopen, and everyone is facing sideways, and then face the other way. We laugh that these people are manipulated like puppets on invisible strings, but this scenario makes us aware of the number of situations in which we mindlessly follow the dictates of group norms and situational forces.
Often times, the mindless submission to group norms has entirely innocuous results. But, in other cases, it can lead to "good people engaging in evil actions." Witness what happened within the controlled environment of the Stanford Prison Experiment. Or, worse, the devastating abuses at Abu Ghraib, which brought otherwise average people to commit atrocious acts. For more read The Lucifer Effect.
