The Art Of Deciphering Facial Expression

'Psychologist Paul Ekman is reputedly the best human lie detector in the world. He has been researching facial expressions for more than forty years. He has learned to move every single muscle in his face at will. Over the years he has created an 'atlas of emotions' with more than ten thousand facial expressions. Ekman's biggest discovery is the 'micro-expression', which shows up on our faces for fractions of a second as an indicator that we're lying and which reveals our true feelings.'
