Often there is a naive belief that witnesses saw what they saw pure and simple. If skepticism is applied to eyewitness accounts, it is only to dissenting witnesses. Yet memory research has shown that memory is not a copy of an event but a reconstruction . People remember what they want. People remember what is plausible.
People remember a blend of observation and conversation about the observation.
