We watch people lying, and we know they're lying. And also, you watch people dealing with lying not very well and not enjoying it. The lying, backstabbing and manipulation the game inspires does indeed make for delightful TV viewing.
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).
