How To Tell Someone Is Lying

Everyone has a tell when they are lying. But, as humans, we don’t always pick up on the clues. New lie-detecting software developed at the University of Michigan is able to analyze these words and gestures to determine with 75 percent accuracy whether someone is lying. A research team looked at video footage from courtrooms, as opposed to footage generated in labs, so that people were in real-life situations where there might be strong enough motives to lie. Their 75 percent success rate was determined by comparing the software’s conclusion to trial outcomes. Here are the six strongest tells when someone is lying, according to the study:

1. Gesturing with both hands
2. Strong eye contact
3. Head nodding
4. Scowling
5. Filler words
6. Third-person pronouns when referring to oneself
