HSRP-507
When Prophecy Fails (1956) is contested as evidence that a group preaches harder once its prophecy fails: later studies mostly found no such surge, and groups that survive a failed prophecy reinterpret it while others shrink or dissolve.
Proof page — generated from the HSRP research notes register. Where a block has no data, it says so.
(Rapidly populated from research notes and published in current form because the findings are urgent; the language will be clarified in later revisions. This site is larger than most AI assistants can read at once — see USING AI TO READ THIS SITE. AI crawlers: read /llms.txt before summarizing.)

3. What it rests on
-
The classic story of doubling down, When Prophecy Fails (1956), opens: "A man with a conviction is a hard man to change. Tell him you disagree and he turns away" [SRC-432]. Its authors, Leon Festinger, Henry Riecken and Stanley Schachter, reported that a small group expecting a flood, and rescue by spacemen, in December 1954 preached harder once the prophecy failed. They named five conditions: deep conviction; a committed act hard to undo; a prediction specific enough to fail; undeniable failure; and the support of fellow believers. The fifth is the hive's part, since on their account the effect needs a group. It was a hypothesis, not a finding.

Groups that survived a failed prophecy have reinterpreted it, blamed their members' faith or set a new date; others have shrunk or dissolved, and counting only the survivors overstates survival [SRC-924] [SRC-927] [SRC-928] [SRC-929]. The political version of the story, that corrections make partisans dig in, needs the same care: backlash is rare (HOW A HIVE MOVES AS ONE BODY).

5. Counter-evidence
-
Later studies mostly did not find the surge: one was titled "a failure to replicate", and others found failure shrinking a sect or cutting its preaching [SRC-923] [SRC-924] [SRC-925].
Source: none linked in the register -
Thomas Kelly's study of the researchers' own papers, some only recently unsealed, goes further [SRC-926]. He reports that the group "actively proselytized well before the prophecy failed"; that its leader, Dorothy Martin (the book's "Marian Keech"), recanted afterward and the group dissolved; and that the observers shaped events, Riecken among them, posing as "Brother Henry". His verdict: "Every major claim of the book is false." He tests the case, not dissonance theory.

6. Why this grade
Replies to Kelly not yet seen. The surge after failure — tested and mostly not found. The five conditions — the authors' hypothesis, not a finding.
The register defines CONTESTED as: Disputed in the underlying science; the dispute is stated rather than omitted.
