284: When Prophecy-Science Fails (w/Thomas Kelly)

In 1954 a doomsday alien cult headed up by Chicagoland housewife Dorothy Martin was waiting for the cataclysmic flood that would herald the arrival of spaceships to transport her and her followers to safety. When the hour came and went and nothing happened, she and her followers made up a Bible’s worth of excuses, saying that the group's penitence and piety had saved them, and so the failure of the prophecy was actually a validation of their new religion. And even though its central claim had been refuted, they accelerated their efforts to proselytize and convert new followers. 

This is the story of the 1956 classic study, When Prophecy Fails, by Leon Festinger, Henry Riecken, and Stanley Schachter.

Problem is—this didn't really happen. At least not that way. As our guest this week Thomas Kelly points out from his investigation of newly unsealed archival materials, the psychologists not only embedded themselves in Martin's cult in a way that provoked their most irrational statements, they fudged the outcome of Martin story to suit their virally popular new theory of cognitive dissonance.
