These 6 clues can help reveal a liar By Elizabeth Armstrong Moore Published December 15, 2015. . Everyone has a tell. Whether we're lying or telling the truth, most of us reveal ourselves through the tiniest physical and verbal clues, and new lie-detecting software developed at the University of Michigan analyzes these words and gestures to determine with 75 percent accuracy whether someone is lying-which may not sound stellar but is far more accurate than humans' ability to determine this, which stands at just over 50 percent. "People are poor lie detectors," says study lead Rada Mihalcea. "There are clues that humans give naturally when they are being deceptive, but we're not paying close enough attention to pick them up. We're not counting how many times a person says 'I' or looks up. We're focusing on a higher level of communication. A key part of the research , she said, is that the team looked at video footage from courtrooms and the Innocence Project, as opposed to footage generated in labs, so that people were in real-life situations where there might be strong-enough motives to lie. "We wanted real data when people are truly lying," Mihalcea says, and the 75 percent success rate was determined by comparing the software's conclusion to trial outcomes. The six strongest tells? Bustle sums them up: gesturing with both hands; strong eye contact; head nodding; scowling; filler words; and third-person pronouns when referring to oneself. Of course, Quartz points out that we can't know with certainty whether a courtroom verdict was correct, or whether all the "liars" were truly lying.
