Remember that time that President Obama shook hands with Iranian President Mahmoud Ahmadinejad? Or what about when Joe Lieberman voted to impeach President Clinton? If you're nodding your head yes, you've got a false memory--neither of these things ever happened, but there is a reason you believe they did.

Slate's national affairs correspondent Will Saletan and experimental psychologist Dr. Elizabeth Loftus will join us to explain the science behind memory falsification and its connection to almost every aspect of our lives--law, advertising, even weight loss therapies.

"The Memory Doctor" is Will Saletan's eight part series on the subject of false memory on Slate.com.
