When you deliver a presentation, your body language is important for one over-riding reason: it creates an instant visual first impression that answers a big question for your audience: “Can I trust this person?”
Until now, science has not been able to isolate the specific physical cues that could cause us to not be trusted. But thanks to Dr. David DeSteno, a professor of psychology at Northeastern University, we now know what gestures can undermine the perception of our trustworthiness.
Dr. DeSteno devised a study in which participants played a cooperative economic game. Half played face-to-face, and half played over the internet. And those who played face-to-face were videotaped from three camera angles.
Small movements that you make–movements you probably aren’t aware of could be the key to whether others trust you… or not.
