The Law of Cause and Effect
It's possible, however, to appear more open and credible by practising open palm gestures when communicating with others. Interestingly, as the open palm gestures become habitual, the tendency to tell untruths diminishes. Most people find it difficult to lie with their palms exposed because of the law of cause and effect. If a person is being open they'll expose their palms, but just having their palms exposed makes it difficult for the person to tell a convincing lie. This is because gestures and emotions are directly linked to each other. If you reel defensive, for example, you're likely to cross your arms across your chest. But if you simply cross your arms you'll begin to experience defensive feelings. And if you are talking with your palms exposed it puts even more pressure on the other person to be truthful too. In other words, open palms can help to suppress some of the false information others may tell and encourage them to be more open with you.
