Vanessa Van Edwards explains why visible hands signal trust: our brains weight gestures 12.5 times more heavily than words. Liars suppress hand movements while truth-tellers use them naturally. Aligning speech with clear gestures makes you appear more credible and engaging.
And this comes back from our caveman days. Now think about this. If you were approached by a stranger caveman and you couldn't see their hands, part of your brain was like, "Well, what's back there? What is she holding? What is she gonna do?" The moment you can see my hands, you see my intention. Are we gonna high five? Are we gonna fist bump? Are we gonna handshake? So first, visible hands. The moment you hop on a Zoom call, the moment you walk into a restaurant, the moment you walk into a room, it's literally like, "I'm a friend. I'm not hiding anything." So visible. Second, and this is my favorite, we believe gestures more than words. Why? Liars don't use hand gestures. Think about it. Liars practice their verbal. So if I'm telling the truth, right? If I say to you, Jennifer, today I have a big idea. Look how big it is. You're like, "Vanessa, that's so small." Ah! Our brain gives 12.5 times more weight to our gestures. So we are looking to gestures to see, are you telling me the truth? Do you have 3 ideas, or do you have 3 ideas? We're looking for congruence with gestures. So when you're explaining what you do, who you are, your ideas, can you explain it with a little bit of gesture? Is it a big idea? Is it 3 different things? It makes you look smarter.
