A timely read, published earlier this week, from the New Yorker‘s science reporter Maria Konnikova, on “why we remember so many things wrong“:
… The day following the explosion of the Challenger, in January, 1986, Neisser, then a professor of cognitive psychology at Emory, and his assistant, Nicole Harsch, handed out a questionnaire about the event to the hundred and six students in their ten o’clock psychology 101 class, “Personality Development.” Where were the students when they heard the news? Whom were they with? What were they doing? The professor and his assistant carefully filed the responses away.
In the fall of 1988, two and a half years later, the questionnaire was given a second time to the same students. It was then that R. T. recalled, with absolute confidence, her dorm-room experience. But when Neisser and Harsch compared the two sets of answers, they found barely any similarities. According to R. T.’s first recounting, she’d been in her religion class when she heard some students begin to talk about an explosion. She didn’t know any details of what had happened, “except that it had exploded and the schoolteacher’s students had all been watching, which I thought was sad.” After class, she went to her room, where she watched the news on TV, by herself, and learned more about the tragedy.
R. T. was far from alone in her misplaced confidence. When the psychologists rated the accuracy of the students’ recollections for things like where they were and what they were doing, the average student scored less than three on a scale of seven. A quarter scored zero. But when the students were asked about their confidence levels, with five being the highest, they averaged 4.17. Their memories were vivid, clear—and wrong. There was no relationship at all between confidence and accuracy…
…[I]f memory for events is strengthened at emotional times, why does everyone forget what they were doing when the Challenger exploded? While the memory of the event itself is enhanced, Phelps explains, the vividness of the memory of the central event tends to come at the expense of the details. We experience a sort of tunnel vision, discarding all the details that seem incidental to the central event…
Much more background at the link. I’ve got to agree with Cole — if you’re surprised that Brian Williams didn’t accurately recollect what happened when that helicopter convoy came under fire, it’s only because you haven’t had enough “what actually happened when the dorm fire broke out / at our wedding / that holiday when your uncle’s Glenn-Beck-fueled rants led to actual fisticuffs” exchanges with your closest companions… yet.
