Lying provokes three main emotions: the guilt linked to the fact of cheating and deceiving someone, the fear of being caught and finally the delight of deception. Both the small and big lies of our existence generally respond to a secret motivation: to give a good self-image, obtaining an advantage (a position, a promotion), avoiding a conflict, pleasing or not causing pain.

If these little arrangements with reality often help us to grease the wheels of life in society or in the family, lying can also arouse in us... a certain pleasure.
