Sagan writes about the story of Paul Ingram. Ingram's daughter reported that her father had sexually abused her. He was told that "sex offenders often repressed memories of their crimes." Ingram was eventually able to have a foggy visualization of the claimed events, and he suggested that perhaps "a demon might be responsible."

Sagan describes how once Ingram started remembering events, so did several other individuals and family members. A "memory recovery" technique was performed on Ingram, and he confessed to the crimes. A medical examination was done on his daughter, where none of the scars she described were actually found.

This seems suspiciously like LLMs that are allowed to run unchecked and how they hallucinate based upon the questions and propositions presented to them.
