Jeff Hancock: The future of lying
Pamela Meyer: How to spot a liar
Dan Ariely: Our buggy moral code
Fascinating stuff. Especially fascinating is when they disagree. Several said you can't see lies in peoples, but others said you can. What's the truth? Are they lying?
Maybe. More likely the paradox is resolvable. Paul Ekman in his book on lying, Telling Lies: Clues to Deceit in the Marketplace, Politics, and Marriage, said that lies change over time as the liar begins to believe his/her lies. Also, knowledge makes liars more slippery, but presumably still catch-able.
