Step-by-step explanation:
In Stanley Milgram's laboratory study, he found that approximately two-thirds or 65% of participants were willing to follow the orders of an authority figure, even when it appeared that following these orders would harm another person. This experiment, known as the Milgram Experiment, aimed to test the extent of people's obedience to authority. The participants were instructed to deliver electric shocks to others who answered questions incorrectly, even to the point of what they believed to be lethal shocks.
