The Stanford Prison Experiment
In 1971, the Stanford Prison experiment put a group of male college students in a mock prison and assigned them to be prisoners or guards - with shocking results.
In 1971, a group of American college students volunteered to be either prisoners or guards in a mock prison in one of the most famous and controversial psychology experiments of recent times. The study, devised by Stanford University professor Philip Zimbardo, came to be known as the Stanford Prison Experiment. Intended to last two weeks, it had to be suspended on the sixth day after those playing the guards subjected their peers, playing the prisoners, to cruel and dehumanising behaviour. Louise Hidalgo reports.
