The Stanford experiment:
The Stanford experiment was a controversial test designed to observe human behavioural changes when “good” people are placed in an “evil” environment. Subjects were assigned the roles of individuals in a make-believe prison, the guards and the prisoners themselves.
The experiment was planned over a 2 week period but concluded early after 5 days, after the physiologist, Professor Zimbardo, came to realise the ethical nature of the experiment.
The subjects ended up reacting in unforeseen ways, some becoming deranged, power mad and insane.
