Falsification of history

Some of our memories feel incontestable as photographs, for example, where we were when 911 happened, or where you met your partner.
These memories are just as flawed

"1973, U.S. political scientist Gregory Markus asked three thousand people to share their opinions on controversial political issues, such as the legalization of drugs. Their responses ranged from “fully agree” to “completely disagree.” Ten years later, he interviewed them again on the same topics, and also asked what they had replied ten years previously. The result: What they recalled disclosing in 1973 was almost identical to their present-day views—and a far cry from their original responses"
Flashbulb memories are as flawed as regular recollections. They are the product of reconstruction. Ulric Neisser, one of the pioneers in the field of cognitive science, investigated them: In 1986, the day after the explosion of the Challenger space shuttle, he asked students to write essays detailing their reactions. Three years later, he interviewed them again. Less than 7 percent of the new data correlated with the initial submissions. In fact, 50 percent of the recollections were incorrect in two-thirds of the points, and 25 percent failed to match even a single detail.
