Final answer:
In Stanley Milgram's study on obedience, 65% of participants administered the highest possible voltage of “shock” to the learner, indicating a willingness to obey authority figures even against their moral judgment.
Step-by-step explanation:
The percentage of Milgram's teachers who delivered the highest possible voltage of “shock” to the learner was 65%. Stanley Milgram's obedience study is a famous psychology experiment designed to measure the willingness of participants to obey authority figures. In this study, participants were instructed to give increasingly higher levels of electric shocks to another person when ordered by an experimenter. Despite hearing the 'learner's' cries and protests, two-thirds of the participants continued to administer the shocks up to the maximum voltage.
The results were astonishing because they challenged our understandings of obedience and conscience, demonstrating that people are likely to follow orders from an authority figure even when those orders conflict with their personal beliefs about what is moral and humane. Milgram's experiment also showed that situational factors influence obedience; variations in the experiment's settings significantly altered compliance rates.
