Body language is easily open to misinterpretation and abuse. In fact, I’ve seen it used to dupe people.
Allan Pease has had many training seminars and written many books about body language. I’ve seen people do many things that Pease preaches and he tells the audience that the person was lying or not telling the complete truth. The truth was in fact that the person was well read on body language and played Pease. Of course Pease always has an answer for everything.
If you really believe in body language there isn’t anything that anyone can say or do to change your mind.
The best liars look you square in the eye.
Stupid people do stupid things
Smart people outsmart each other
