The Milgram experiment was a series of seminal social psychology experiments conducted by Yale University psychologist Stanley Milgram, which measured the willingness of study participants to obey an authority figure who instructed them to perform acts that conflicted with their personal conscience.
In Milgram's first set of experiments, 65 percent of experiment participants administered the experiment's final 450-volt shock, though many were very uncomfortable doing so; at some point, every participant paused and questioned the experiment, some said they would refund the money they were paid for participating in the experiment.
NO PARTICIPANT STEADFASTLY REFUSED TO ADMINISTER SHOCKS BEFORE THE 300-VOLT LEVEL.
Student 1 : Wow that took some guts! Carla sure knows how to stand up to the 'ol prof
Student 2 : yeah, a real Milgram's exception if I ever saw one...
