You may think that fidgeting and not making eye contact are telltale signs that someone’s lying to you. But according to Harvard Business School professor Amy Cuddy, there is no one nonverbal cue that’s a dead giveaway.
Lying is hard work,” Cuddy says. “We’re telling one story while suppressing another, and if that’s not complicated enough, most of us are experiencing psychological guilt about doing this, which we’re also trying suppress. We just don’t have the brainpower to manage it all without letting something go — without ‘leaking.'”
What’s the giveaway?
The best way to catch these “leaks” is to look for differences between what people are saying and what they are doing, she says. Conflicting emotions, like a happy tone of voice paired with an agitated facial expression, can be particularly telling.
Not the words, but actions. It’s easy to detect lying politicians. Their lips are moving.
