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.

Daniel L. Schacter: Are all of your memories real?

Are all of your memories real?

Exploring the malleability of memory, a study reveals a quarter of participants constructed false memories of being lost in a mall.

Memory's fallibility is demonstrated by subjects misattributing a campus visit from a photograph, challenging our perception of reality.

Our current beliefs can retroactively alter our memories, as shown when participants adjusted their past opinions on marijuana legalization.
