When Prophecies Fail: A Social and Psychological Study of a Modern Group That Predicted the Destruction of the World is a classic 1956 book by Leon Festinger, Henry W. Riecken, and Stanley Schachter. It documents the behavior of a small UFO cult that believed the world would end on a specific date, and how they rationalized the failure of their prophecy, introducing the concept of cognitive dissonance to a wider audience.
I remember reading the work of Leon Festinger the guy that coined the term cognitive dissonance yes when prophecies fail he also did that

"Leon Festinger is mentioned as the 'guy that coined the term cognitive dissonance' and the speaker adds 'prophecies fail he also did that,' strongly implying the book 'When Prophecies Fail' as another significant work by the author, directly relevant to the discussion of how people handle conflicting ideas."
