“He who has eyes to see and ears to hear may convince himself that no mortal can keep a secret. If his lips are silent, he chatters with his fingertips; betrayal oozes out of him at every pore.” ~Sigmund Freud
In my profession it is important to know if someone is lying to me or more importantly to themselves. Whether it is a small lie or a malicious lie, everyone lies at some point. Research shows that on average, people lie 10 times per day. Many people lie to keep the peace or to inflate their ego. Others might lie because they are pathological liars or have a personality disorder.
