#lie-detection

We're told to "trust our gut," and to look for shifty eyes or nervous fidgeting. Detectives in movies and TV shows spot liars through micro-expressions. Yet across hundreds of experiments, the average rate of accurate lie-truth discrimination is 54% (Bond & DePaulo, 2006). In fact, computers often outperform judges on deciding who will skip bail, and seasoned police officers who are most confident in their "lie-detecting" abilities are often the least accurate (Gladwell, 2019).
