Stanford Prison Experiment Documentary
Google video is hosting a 50-minute documentary about the Stanford Prison Experiment.
From Wikipedia:
“The Stanford prison experiment was a landmark psychological study of the human response to captivity, in particular, to the real world circumstances of prison life, and the effects of imposed social roles on behavior. It was conducted in 1971 by a team of researchers led by Philip Zimbardo of Stanford University. Volunteers played the roles of guards and prisoners and lived in a mock prison built in the basement of the Stanford psychology building. However, the experiment quickly got out of hand and was ended early.”
An excellent German film called “Das Experiment” is based off these events.
