Episode notes
Failed Flying Saucer Prophecy
- Dorothy Martin predicted an apocalyptic flood and promised followers rescue by flying saucers in 1954.
- When the saucers never arrived she recanted, her group dissolved, and proselytizing efforts stopped.
Canonical Account Challenged
- When Prophecy Fails (1956) claimed the group doubled down and recruited after the failed prophecy, introducing cognitive dissonance theory to the public.
- New archival material shows those central claims were false and the authors knew they were false.
Archival Evidence Alters Story
- Newly unsealed documents reveal the group proselytized before the prophecy and abandoned beliefs quickly afterward.
- The documents also expose ethical violations by the researchers during the study.
