劇情概要：
"Honesty - The Truth of Lies" is a documentary that explores how people lie and why they lie. This movie is based on behavioral experiments, measuring our tendency to lie - sometimes even unconsciously. On a more personal level, from well intentioned lies to destructive deception, people share the true stories of the lies they tell in front of the camera. Experts have studied the reasons behind our behavior and the meaning of our dishonesty. Behavioral scientist Dan Ariely combines these elements and guides us in discovering complex truths about lies.
