The Stanford Prison Experiment Showed How Quickly People Adopt Roles
In 1971, psychologist Philip Zimbardo randomly assigned college students to roles as prisoners or guards in a mock prison. Within just six days, the experiment had to be stopped: 'guards' became sadistic and abusive, while 'prisoners' suffered genuine psychological breakdowns. The experiment demonstrated how powerfully situational roles and authority can override individual morality — though the study's methods have since been heavily criticized for ethical violations.
