Milgram's experiment has been denounced repeatedly by ethicists, commentators, and fellow psychologists. At the same time, the results surprised many experts within the field by showing what ordinary people are capable of doing to one another. What result was likely the most surprising?

65% of participants delivered the full Ange of shocks, going up to 450 volts.

Explanation:

One of the most famous studies of obedience in psychology was carried out by Stanley Milgram, a psychologist at Yale University. He conducted an experiment focusing on the conflict between obedience to authority and personal conscience.

Milgram (1963) examined justifications for acts of genocide offered by those accused at the World War II, Nuremberg War Criminal trials. Their defense often was based on "obedience" - that they were just following orders from their superiors.

Milgram (1963) was interested in researching how far people would go in obeying an instruction if it involved harming another person.

Stanley Milgram was interested in how easily ordinary people could be influenced into committing atrocities, for example, Germans in WWII.

The result of the experiment:

65% (two-thirds) of participants (i.e., teachers) continued to the highest level of 450 volts. All the participants continued to 300 volts.
