A student of Kurt Lewin, Festinger reshaped social psychology with social comparison theory (1954) and cognitive dissonance theory (1957). His observational study of a small religious group after a failed prophecy (When Prophecy Fails, 1956) remains a classic on how beliefs meet disconfirmation. He taught at MIT, Minnesota, and Stanford.
