What was Stanley Milgram's obedience experiment?
"I was just following orders" experiment.
In a teacher/learner context, subject applied increasingly high voltage shocks when the learner gave a wrong answer. 65% delivered all voltages because the researcher (authority) told them they he took responsibility, or because he ordered them to do so.
Subsequent studies (22 hospitals study) show that if you have a chance to confer with someone or you know what you are doing, your chances of resisting authority figures increase.
