I was watching the T.V. show Lie To Me today and was very impressed with the accuracy it portrayed micro expressions. The show is loosely based off of Paul Ekman, a well-renown psychologist, and his study of subliminal facial expressions in day-to-day conversation.

He spent years studying the muscle movements in facial expressions to compile a detailed account for what various muscle contractions signify. Languages vary throughout the world with different contexts and origins. Micro expressions, on the other hand, are universals. Signs of happiness and aggressiveness are uniform throughout mankind, and a doctrine of our biological make-up.
