Pamela Meyer is the author of Liespotting, and she recently gave a fascinating speech at the TED Conference where she explained the history, purpose, and detectability of lies. Research indicates that on any given day the average person is lied to between 10-200 times, sometimes with devastating results. On a larger scale, lies can change the course of civilization, so understanding the chemistry of both a lie and a liar can help us diffuse this weakness in human evolution, and set us on a path towards a value worth saving — honesty.
