Micro-expressions show you lie

Human facial micro-expressions are key aspects in determining whether or not a person is lying, according to research from the University of Buffalo. Social psychologist Professor Mark Frank has been studying human expression with particular focus on the movement of certain muscles in the face. By combining computer technology with his knowledge of social psychology dealing with the nature of emotion, Frank was able to derive his findings from testing and observing various involuntary muscle movements on people under different circumstances. Frank explains “Fleeting facial expressions are expressed by minute and unconscious movements of facial muscles like the frontalis, corregator and risorius and these micro-movements, when provoked by underlying emotions, are almost impossible for us to control.” This technique may prove to be a security benefit if such procedure can be implemented. For example it could be used by police investigators to identify criminal suspects or potential terrorists.
