Power and Politics in Organizations

The Zimbardo Study

Philip Zimbardo, a researcher at Stanford University, conducted a famous experiment in the 1970s. While this experiment would probably not make it past the human subjects committee of schools today, at the time, he was authorized to place an ad in the paper that asked for male volunteers to help understand prison management. After excluding any volunteers with psychological or medical problems or with any history of crime or drug abuse, he identified 24 volunteers to participate in his study. Researchers randomly assigned 18 individuals to the role of prisoner or guard. Those assigned the role of "prisoners" were surprised when they were picked up by actual police officers and then transferred to a prison that had been created in the basement of the Stanford psychology building. The guards in the experiment were told to keep order but received no training. Zimbardo was shocked with how quickly the expected roles emerged. Prisoners began to feel depressed and helpless. Guards began to be aggressive and abusive. The original experiment was scheduled to last 2 weeks, but Zimbardo ended it after only 6 days upon seeing how deeply entrenched in their roles everyone, including himself, had become. Next we will examine the relationship between dependency and power.
