How to Spot a Liar
In this TED Talk, author Pamela Meyer talks about how to spot a lie. You've seen Lie to Me, right? This is roughly the same notion (albeit not in fast-moving TV form), though Meyer notes that lie-spotting is a discipline that's not about calling people out on the fly -- it's a bit more subtle.
Recommended for: those interested in psychology, professionals concerned about being conned, those interested in Koko the gorilla's lies, and anyone interested in learning some basic lie-spotting tips. (Meyer also has a book covering the topic in depth.)
Factoid from Meyer: extroverts lie more than introverts. Go introverts!
