The reader may ask, ‘Do you mean that if I tell lies with my palms visible, people will believe me?’ The answer to this is yes - and no. If you tell an outright lie with your palms exposed, you may still appear insincere to your listeners because many of the other gestures that should also be visible when displaying honesty will be absent and the negative gestures used when lying will be visible and therefore inconsistent with the open palms. As already noted, con men and professional liars are people who have developed the special art of making their nonverbal signals complement their verbal lies. The more effectively the professional con man can use the non-verbal gestures of honesty when telling a lie, the better he is at his vocation.
It is possible, however, to make yourself appear more credible by practising open palm gestures when communicating with others; conversely, as the open palm gestures become habitual, the tendency to tell untruths lessens. Interestingly, most people find it difficult to lie with their palms exposed and the use of palm signals can in fact help to suppress some of the false information others may give. It also encourages them to be open with you.
