Can behavior clusters help determine a lie? Tim Levine on deception detection science

Many people think there are telltale signs of lying — shifty eyes, nervous fidgeting, maybe a quick smile — that can give someone away to trained observers. But according to decades of research, that’s a myth. Still, some scientists push back on that consensus. A recent paper by well-known researcher David Matsumoto (of the company Humintell) argues that combinations of nonverbal cues might be highly useful for revealing deception. In this episode, I talk with deception researcher Tim Levine, author of Duped and creator of truth-default theory, about whether that claim holds up — and what the science says about our ability to read lies using body language.
