Presence is an ineffable quality—something about the way a person carries her or himself that attracts our attention and (often) our buy-in. Here, Amy Cuddy teaches us to recognize the telltale signs of presence and the “leaks” that give away its opposite—inauthenticity.Three Indicators of PresenceBelief in one’s story. The person truly buys what she is selling.Confidence, not arrogance. The person is secure in his thoughts and comfortable with being challenged. He’s open to constructive feedback.Synchrony across verbal and non-verbal channels. The person’s words match her body language and she appears unchoreographed.Spotting a LiarEye contact is not a good way to detect lying.
