Even the world's best detect lies only 50% of the time
Dreeke pushes back on TV portrayals like Lie to Me. His friend Joe Navarro, a world-renowned body language expert, will be the first to say the best people on earth detect deception only about 50 percent of the time from nonverbals alone. Nonverbals reveal stress and comfort, not lies, and remembering negative events is stressful too, so you cannot reliably read deception from body language.
- Nonverbal-only deception detection is roughly 50% accurate, no better than chance
- Body language shows comfort versus stress, not truth versus lies
- Recalling negative events is stressful, muddying any 'lie' signal
- Screen dramatizations of micro-expression mind-reading are fiction
“the best people in the world including Joe can only detect deception 50% of the time... using a nonverbal detection alone”
