This document discusses three main forms of social influence: conformity, compliance, and obedience. It provides details on seminal studies conducted by Solomon Asch and Stanley Milgram to experimentally examine conformity and obedience. Asch's line judgment experiment demonstrated that people will conform to a group norm even when it is clearly wrong. Milgram's obedience studies surprisingly found that around two-thirds of participants were willing to administer what they believed were dangerous electric shocks when instructed to do so by an authority figure. The document analyzes the psychological factors underlying each type of social influence.
