Ekman's work on facial expressions had its starting point in the work of psychologist Silvan Tomkins. Ekman showed that contrary to the belief of some anthropologists including Margaret Mead, facial expressions of emotion are not culturally determined, but universal across human cultures and thus biological in origin. Expressions he found to be universal included those indicating anger, disgust, fear, joy, sadness, and surprise. Findings on contempt are less clear, though there is at least some preliminary evidence that this emotion and its expression are universally recognized.
In a research project along with Dr. Maureen O'Sullivan, called the Wizards Project (previously named the Diogenes Project), Ekman reported on facial "microexpressions" which could be used to assist in lie detection. After testing a total of 20,000 people[6] from all walks of life, he found only 50 people that had the ability to spot deception without any formal training. These naturals are also known as "Truth Wizards", or wizards of deception detection from demeanor.[7]
He developed the Facial Action Coding System (FACS) to taxonomize every conceivable human facial expression. Ekman conducted and published research on a wide variety of topics in the general area of non-verbal behavior. His work on lying, for example, was not limited to the face, but also to observation of the rest of the body.
