There's No #1 Sign Someone Is Lying

There's no #1 sign someone is lying. Across 206 research reports and more than 24,000 judges, people caught lies 54% of the time; a coin gets 50. Play Two Truths and a Lie with us and see what actually helps. In this video: why we believe 61% of truths but catch only 47% of lies, what happens with the sound off, the 'they look away' belief found in 75 countries (and why it predicts almost nothing), the up-and-to-the-right rule that failed three tests, what Mehrabian's 7% really covered, the power-pose study that didn't replicate (and what's left of it), whether police and customs officers beat you, how often people really lie in the US, UK, South Korea and Japan, and the two things that do work: holding back what you know, and checking what's said against the facts.
