Stanley Milgram (1963) designed a baseline procedure that could be used to assess obedience levels
Baseline procedure
1. 40 American men volunteered
2. Participant drawn as 'Teacher'
3. Participant ordered to give shocks to 'Learner'
4. Shocks were fake but participant didn't know this
Every participant delivered all the shocks up to 300 volts
12.5% stopped at 300 volts and 65% continued to the highest level of 450 volts
Participants showed signs of extreme tension, many sweating, trembling, stuttering, biting lips, groaning, digging fingernails into hands, and three had full-blown uncontrollable seizures
Before the study, psychology students estimated that no more than 3% of participants would continue to 450 volts
84% of participants said they were glad to have participated
Milgram's conclusions
German people are not 'different', American participants were willing to obey orders even when they might harm another person
A French documentary replicated Milgram's findings, with 80% of participants delivering the maximum shock of 460 volts
