When Prophecy Fails: A Study of Cognitive Dissonance and Belief Under Disconfirmation - Paperback

by Leon Festinger (Author), Henry W. Riecken (Author), Stanley Schachter (Author)

When Prophecy Fails is a landmark study in social psychology examining what occurs when deeply held beliefs collide with disconfirming reality.

Originally published in 1956, this influential work by Leon Festinger, Henry W. Riecken, and Stanley Schachter documents the internal dynamics of a millenarian movement whose prophecy of imminent catastrophe failed to materialise. Rather than dissolve under the weight of contradiction, many adherents intensified their commitment. From this field study emerged one of the most enduring theories in modern psychology: cognitive dissonance. Observed under natural conditions, the movement provided rare empirical evidence of how belief systems adapt when confronted by failure, and how social reinforcement can strengthen conviction in the face of disproof.

Conducted under the auspices of the Laboratory for Research in Social Relations at the University of Minnesota and supported in part by the Ford Foundation, the study remains foundational to contemporary understandings of persuasion, group identity, ideological resilience, and motivated reasoning. More than a historical case study, it is a disciplined examination of the mechanisms by which individuals preserve meaning in the aftermath of prophetic collapse.
