There's plenty of science behind micro-expressions and detection of deception.
Paul Ekman [0] is "ranked 59th out of the 100 most cited psychologists of the twentieth century" and I thought the TV show based on his research [1] was very entertaining. (I am surprised that the article used the phrase "micro-expression" without any reference to Ekman's work.)
