Flawed Eyewitness Memories

I describe a study I'd conducted in which subjects watched a film of a robbery involving a shooting and were then exposed to a television account of the event which contained erroneous details. When asked to recall what happened during the robbery, many subject incorporated the erroneous details from the television report into their account. Once these details were inserted into a person's mind through the technique of exposure to post-event information, they were adopted as the truth and protected as fiercely as the "real," original details. Subjects typically resisted any suggestion that their richly detailed memories might have been flawed or contaminated and asserted with great confidence that they saw what their revised and adapted memories told them they saw.
