How To: Recognize A Liar's Body Language
Getting lied to, and then buying into it, is almost always a bad thing.
(Sometimes it's life and death.) Really good liars are everywhere, but they
can't control what they don't know they're doing. Here's some stuff that
most people will automatically do when weaving a yarn.
1. If the liar actually believes they are lying, and that it is wrong,
then watch for negative self evaluation gestures. These are usually touching
of the nose or ears. Yes it sounds silly. Yes, we almost all do it. No, we
don't realize it.
2. Eye contact almost always weakens during the actually telling of the
lie. Except if someone's doing that "look in my eyes and tell me" thing. In
which case eye contact is mandatory.
3. Most liars tell lies "palms down". It's a subconscious move that is
defensive and deceptive. Showing someone your palms makes you feel
vulnerable.
4. Most liars are also slouchers. Our backs naturally straighten when
we are proud and confident. Liars faking confidence, are rarely either.
5. Humans eyes generally move up and to left if their brain is doing
visual or audio construction. They will generally move to the upper right
when doing recall. Just remember: Liars go Left, the Righteous go Right.
None of these mannerisms on their own is a solid lock. But if you get
someone presenting 3 or 4 of them, they're selling you something you
shouldn't be buying.
