Milgram’s experiment in 1960 by social psychologist Dr. Stanely Milgram’s (1963‚ 1965) was a controversial experiment. He researched the effect of authority on obedience.

Zimbardo was the mastermind of the Stanford Prison Experiment‚ which was a psychological experiment that determined the roles of members in a society that became a fiasco (“Philip G. Zimbardo” 1). The experiment left emotional and mental scars on mock-prisoner lives. The Stanford Prison Experiment (SPE) illustrates the way a person changes when a label and power is all of a sudden given to hoax guards in order to control fraud prisoners.
