How Can I Tell If Someone's Lying?

Here are six tells from a former FBI agent.

1. Pursing the lips. Stressed people (and chimps, FYI) do it.
2. Crinkling the nose. Of course, there could just be a bad souffle nearby.
3. Idle stroking of the throat. It's a vulnerable area.
4. Raising the shoulders. It's a non-committal sign.
5. Clearing the throat. Or if the voice pitch rises.
6. Rubbing the eyes. Even blind people do this when being evasive.

Useful to keep in mind during the next crucial conversation with a co-worker or child.
