In a 1990's study, participants recalled getting lost in a shopping mall as children. Some shared these memories in vivid detail, but there was one problem: none of these people had actually gotten lost in a mall. They produced these false memories after psychologists told them they'd gotten lost and parents confirmed it. So what's going on? Daniel L. Schacter explores the fallibility of our memory.
