There's also mental editing, where we recall what "must" have happened.  My favourite example was one where a couple of men burst into a lecture, one of them stabbed the other with a banana, and they ran out.  Almost everyone reported that he'd been stabbed with a knife, because it couldn't have been a banana, could it?

More ominous was another where a black and a white man ran in and the white man stabbed the black man.  When interviewed afterwards more than half the class recalled that the black man had stabbed the white man.  That was in the 70s, I'd like to hope that if it were repeated today the results would be different.

Oh better far to live and die under the brave black flag I fly,
Than play a sanctimonious part with a pirate head and a pirate heart.
