When an
example of the Mandela Effect is disprovable with absolute certainty, but a person
still believes that their
perception of events is completely correct and begins to rationalise with increasing layers of unbelievability and absurdity.
Person A: Nelson Mandela was released from
prison in 1990.
Person B: No he wasn't, he died in
prison in the 1980s. Any other attempts to convince you otherwise have been written by a rogue artificial intelligence.
Person A: Not true. I met Nelson Mandela.
Person B:
Well, actually, you didn't, you were possessed by a demon that made you think you met Nelson Mandela, but you didn't really.
Person A: I think you're suffering from the Mandildo Effect.
