'Poker Face's Bullsh*t Detector Is a Real Thing

Although Charlie Cale (Natasha Lyonne) has an almost superhuman ability to tell when people are lying in Poker Face, it turns out there actually are some ways to detect lies. Popular belief holds that there are body language cues that are “tells” for when someone is fibbing. In fact, most of these cues are not highly correlated with lying in scientific experiments (other than sometimes a high-pitched voice or fidgeting). Instead, human lie detectors pay close attention to what the liar is saying (or not saying) rather than how they are saying it.
