Stanford Prison Experiment/SPE/Zimbardo: In his August 1971 experiment in a cellar at Stanford University, Philip Zimbardo brought together two groups of 20 men each from a group of 70 who had volunteered for a psychological study for an experiment that was to last two weeks. The men in one group were supposed to be prisoners, the other guards. There was also an (alleged) superior, the deputy warden, who in reality was Zimbardo himself. A few days after the preliminary meeting, the members of the "prison group" were arrested and blindfolded by disguised „police officers“ and taken to the cellar of Stanford University. So they should believe it was a realistic situation.
The behaviours of both groups should result in a self-developing dynamic.
After a few days such excessive behaviours developed that the experiment had to be stopped on the sixth day. >Tyranny/psychological theories, >Tyranny/Reicher, >Method/Zimbardo.

Results: the study was never written up in detail in a peer-reviewed psychology journal and hence no single ‘authorized’ publication provides a definitive account of events. Instead, key accounts of the study’s findings are provided in different outlets produced for different audiences, in different forms,

and at different points in time.
Phases: 1) neither prisoners nor guards were ‘completely into their roles’ and both groups displayed ‘considerable hesitation and some awkwardness’ (Zimbardo, 2007(1): 54).
2) Rebellion. Angered and frustrated by the treatment that the guards were starting to mete out, some of the prisoners started to formulate plans for rebellion.
3) Tyranny. The guards started by calling for reinforcements and together they decided to meet force with force.

As the study moved towards its conclusion, then, it was not just the guards and prisoners who succumbed to the power of their role, but also the experimenters.

(…) the scene was set for the guards to progressively dominate, oppress, and brutalize the prisoners.

Importantly, not all of the guards went down this path. Zimbardo observes that ‘about a third became tyrannical in their arbitrary use of power … [becoming] quite inventive in their techniques of breaking the prisoners and making them feel worthless’ (Zimbardo 1971(2): 154). Of the remaining guards, some strove to be ‘tough but fair’ while others endeavoured to be ‘good guards’, being friendly to the prisoners and doing them small favours. However, it is for the behaviour of the most abusive guards – epitomized by ‘John Wayne’ – that the study is best known.
