Lies and leakage[edit] There is no sign of deceit itself. There is no gesture, facial expression, nor muscle twitch that in and of itself means that a person is lying. There are only clues that the person is poorly prepared and clues of emotions that dont fit what the person is saying. These are what provide leakage or deception clues.[30] Microexpressions are used as a way to detect if there is something off in a statement that a person mentions. They do not determine a lie but are a form of detecting concealed emotion. Dr. David Matsumoto explains that one must not conclude that someone is lying if a microexpression is detected but that there is more to the story than is being told.[31] Universality[edit] A question commonly asked is whether facial expressions within microexpressions are universal no matter what their background. Charles Darwin wrote that facial expressions of emotion are universal, not learned differently in each culture; that they are biologically determined, the product of mans evolution.[32] Many writers have disagreed with this statement. Dr. David Matsumoto however agreed with this statement in his study of sighted and blind Olympians. Using thousands of photographs captured at the 2004 Olympic and Paralympic Games, Matsumoto compared the facial expressions of sighted and blind judo athletes, including individuals who were born blind. All competitors displayed the same expressions in response to winning and losing.[33] Dr. Matsumoto discovered that both blind and sighted competitors displayed similar facial expression, during winnings and loss. Evidence that our ability to modify our faces to fit the social setting is not learned visually.[33] Dr. Paul Ekman also agreed that some facial expressions are indeed universal while there are cultural differences in when the expressions are shown.
