The guards in the study were given khaki-colored uniforms and mirrored sunglasses, so they had an anonymous and sinister look. They wore billy clubs, keys, and handcuffs. They received no special instructions from Zimbardo. He just told them to play the role of prison guards and to maintain order in the mock prison.

In 1975, social psychologist Philip Zimbardo conducted an experiment demonstrating that violent and aggressive behavior could be elicited from typical college students simply by asking them to act in the role of a prison guard. Zimbardo was curious about the psychological effects of imprisonment, so he arranged for students to enact the roles of prisoners or prison guards. Male subjects were recruited through newspaper ads offering them $15 a day to participate. Seventy-five men applied to participate, and 19 were chosen. A battery of tests was employed to select those with the most stable personalities. Volunteers were randomly assigned to play prison guard or prisoner through the flip of a coin.

The Zimbardo prison study resembles the Milgram obedience study in several ways. It put ordinary citizens in the role of torturers or bullies, in part by appearing to remove their personal responsibility for their actions. The Zimbardo research, like the Milgram study, raised protests about abusive treatment of experimental subjects. However, like Milgram, Zimbardo exercised extraordinary care in debriefing his subjects and conducting follow-up interviews to make sure none suffered lasting harm. The Zimbardo prison study, like the Milgram study, was valuable in showing how easily ordinary people could slip into a brutal and aggressive pattern of behavior, especially if it was approved by an authority.

After a day and a half, one of the prisoners had to be released because of uncontrolled crying, depression, fits of rage, and disorganized thinking. A few days later, the same thing happened to three additional prisoners. By the fifth day, all the volunteer prisoners asked to be released from the experiment, even though it meant they would forfeit their pay. One subject developed a skin rash over his whole body after having his appeal rejected by a mock Parole Board. On the sixth day the experiment was terminated because "the experience dramatically and painfully transformed most of the participants in ways we did not anticipate, prepare for, or expect" (Haney & Zimbardo, 1998).

To investigate how easily people conform to the roles of guard and prisoner in the simulated prison situation
How do social situations distort personal identities?
Zimbardo put undergraduate students from Stanford (where he taught) to simulate the dehumanizing effect of being put in a real real prison for a time period of 2 weeks
The condition of the prisons are due to the nature of the guards and prisoners
(The personality of the people make up the situation of the place)
found that it is the situation, not the people that effect conditions
