The stanford prison experiment demonstrated the powerful influence of: question 28 options:

a. explicit orders and direct pressure to obey by an authority figure.

b. the bystander effect.

c. the indirect pressure of situational roles and implied social rules.

d. the just-world hypothesis.

The correct answer is C. the indirect pressure of situational roles and implied social rules.
The experiment took place in 1971, when a group of 24 volunteering students acted as either police officers or prisoners, in order for the researcher, Philip Zimbardo, to test his hypothesis. He wanted to see whether the prisoners would commit crimes within prison if subjected to psychological torture.
