In the article, "Making Mona Lisa Smile", Prof. Thomas Huang explains how muscles contribute to a large portion of reading facial expressions. At one point he claims, "To an expert, faces dont lie; these muscle clues are sometimes used to spot when a "smiling" politician or celebrity aren't being truthful" (D'Alto, 8). By pointing the idea out of spotting false facial expressions, the Facial Action Coding System can be used in schools and other places to help detect people who may be lying or trying to hide the truth. Instead of adults trying to pry kids open and "spill the beans", they can simply use the computer system to recognize certain facial expressions and then start from there.
