Did you ever have the experience of going through an old photo album or home movie you haven’t seen in years, and saying to yourself…”Wait a minute…that’s not how it was!” If so, you’re already aware of how tricky a thing memory is. You may have an entirely vivid and seemingly reliable memory of some particular aspect of the past which those old photos prove to be false. While these seem like oddball experiences, modern psychology is recognizing that much of our memory works this way. It’s by no means the stable, objective record of events people take it to be. In fact, people’s memories can rather easily be changed and new ones inserted. That’s a surprising claim to make, so let me say it again: people’s memories can be changed. It’s called “false memory syndrome,” and has nothing to do with age or intelligence.
