You’re being lied to right now.
Research shows we’re lied to between 10 and 200 times per day. The average person detects deception at barely 54% accuracy — just above a coin toss.
The critical insight
There is no body language signal for deception itself. What you’re measuring is stress— deviations from someone’s baseline behavior. The skill isn’t spotting lies. It’s recognizing stress where there shouldn’t be any.
