This interesting clip from the World Science Festival gives us two stories that show how lousy the human memory really is, and how easily it can be tricked. The first anecdote is about a guy who held onto the memory of an incident that occurred at a birthday party, only to learn that the incident never happened at all; the second story is about a woman who unintentionally confused a TV program with reality and almost sent an innocent guy to jail for rape. (And I think it's bad when I have trouble remembering where I put the remote...)

Meanwhile, in this piece for Scientific American, Greg Boustead points out that your memories aren't reliable, even when they concern dramatic/traumatic events you think are seared into your skull.
