  Looking at whether or not participants could tell the difference between truth and lies, on average, players at the start of the game scored "not much better than chance — about 56 percent accurate. By the end of the game they're 68 percent accurate, and that's just playing for about an hour. Law enforcement participants started the game with higher accuracy, 62 percent, and improved to 78 percent. That's a big jump."
  "If a person said, 'I think she wasn't truthful because wasn't looking at me,' the game would tell them, 'Eye contact not a reliable cue, instead you should rely on these real cues,'" she continued. "We try to teach people not to look for individual cues, like tapping a foot or looking up. There is no Pinocchio's nose, no one thing that will tell you definitively if someone is lying. People will be different, and do different things."
  "There is no one cue that's our magic bean to tell us when someone is lying," Dunbar added, "but all these cues added up together — that says something."
  "One interesting finding is that people tend to be better at detecting truthful statements, because of that truth default," said Dunbar. (She also is studying how people develop trust when they are lying as part of a Multidisciplinary University Research Initiative grant funded by the Department of Defense.) "Their accuracy in assessing lies is often below 50 percent because they don't guess 'lie' often enough. And the game doesn't make them more accurate in guessing lies, but it does improve accuracy in guessing truth and overall knowledge about deception."
