Why Body Language Can Hurt Your Credibility
Using exaggerated gestures while talking can undermine others' trust
Ideally, body language should be a natural form of communication that is mostly unconscious. Some people put too much energy into their body language, and it comes across as insincere and phony.
When you try to impress people with overt gestures, they will often become suspicious, lowering the trust between you and other people. I will describe how overdone body language impacts us in a couple areas, starting with the entertainment world.
Consider the movie, Dumb and Dumber. The two principle characters (played by Jim Carrey and Jeff Daniels) constantly overdid their gestures and body language to the point where it became laughable. Actually, by the time the movie was half over, I was already tired of the humor.
