I want to start by offering you a free no-tech life hack, and all it Cloze (1): JXUwMDJhJXUwMDE3JXUwMDE0JXUwMDA0JXUwMDFjJXUwMDFiJXUwMDE3JXUwMDE2 of you is this: that you change your posture for two minutes. But before I give it away, I want to ask you to right now do a little audit of your Cloze (2): JXUwMDNhJXUwMDBkJXUwMDBiJXUwMDFk and what you're doing with your body. So how many of you are sort of making yourselves smaller? Maybe you're hunching, crossing your legs, maybe wrapping your ankles. Sometimes we hold onto our Cloze (3): JXUwMDM5JXUwMDEzJXUwMDFmJXUwMDFl like this. Sometimes we spread out. (Laughter) I see you.So I want you to pay attention to what you're doing right now. We're going to Cloze (4): JXUwMDNiJXUwMDBjJXUwMDAyJXUwMDA4 back to that in a few minutes, and I'm hoping that if you learn to tweak this a little bit, it could significantly Cloze (5): JXUwMDNiJXUwMDBiJXUwMDA5JXUwMDBmJXUwMDA5JXUwMDAy the way your life unfolds.

So, we're really fascinated with body language, and we're Cloze (6): JXUwMDI4JXUwMDExJXUwMDEzJXUwMDA2JXUwMDFkJXUwMDBhJXUwMDE2JXUwMDE5JXUwMDBkJXUw MDEzJXUwMDFlJXUwMDE1 interested in other people's body language. You know, we're interested in, like, you know — (Laughter) — an awkward interaction, or a smile, or a contemptuous glance, or maybe a very awkward wink, or maybe even something like a Cloze (7): JXUwMDMwJXUwMDA5JXUwMDBmJXUwMDBhJXUwMDE3JXUwMDFiJXUwMDA5JXUwMDBhJXUwMDBl .

Narrator: Here they are arriving at Number 10. This lucky Cloze (8): JXUwMDI4JXUwMDFmJXUwMDAzJXUwMDA1JXUwMDBhJXUwMDA2JXUwMDA4JXUwMDBjJXUwMDBm gets to shake hands with the President of the United States. Here comes the Prime Minister -- No. (Laughter) (Applause)

Amy Cuddy: So a handshake, or the lack of a handshake, can have us Cloze (9): JXUwMDJjJXUwMDE1JXUwMDBkJXUwMDA3JXUwMDAyJXUwMDA3JXUwMDA5 for weeks and weeks and weeks. Even the BBC and The New York Times. So obviously when we think about nonverbal behavior, or body language -- but we call it nonverbals as social Cloze (10): JXUwMDJiJXUwMDEwJXUwMDBhJXUwMDBjJXUwMDBiJXUwMDFhJXUwMDFkJXUwMDFhJXUwMDA3JXUw MDA3 -- it's language, so we think about communication. When we think about communication, we think about interactions. So what is your body language communicating to me? What's mine communicating to you?

And there's a lot of reason to Cloze (11): JXUwMDNhJXUwMDA3JXUwMDA5JXUwMDA1JXUwMDBjJXUwMDEzJXUwMDEz that this is a valid way to look at this. So social scientists have spent a lot of time looking at the effects of our body Cloze (12): JXUwMDM0JXUwMDBkJXUwMDBmJXUwMDA5JXUwMDEyJXUwMDE0JXUwMDA2JXUwMDAy , or other people's body language, on judgments. And we make sweeping Cloze (13): JXUwMDMyJXUwMDFmJXUwMDExJXUwMDAzJXUwMDBhJXUwMDA4JXUwMDBiJXUwMDFhJXUwMDA3 and inferences from body language.And those judgments can predict really meaningful life outcomes like who we hire or Cloze (14): JXUwMDI4JXUwMDAyJXUwMDFkJXUwMDAyJXUwMDAyJXUwMDFiJXUwMDEx , who we ask out on a date. For example, Nalini Ambady, a researcher at Tufts University, shows that when people watch 30-second soundless clips of real physician-patient interactions, their judgments of the physician's niceness  Cloze (15): JXUwMDI4JXUwMDAyJXUwMDE3JXUwMDAxJXUwMDBkJXUwMDBhJXUwMDE3 whether or not that physician will be sued. So it doesn't have to do so much with whether or not that physician was incompetent, but do we like that person and how they interacted? Even more Cloze (16): JXUwMDNjJXUwMDE2JXUwMDEzJXUwMDBjJXUwMDBjJXUwMDE1JXUwMDFkJXUwMDBh , Alex Todorov at Princeton has shown us that judgments of political candidates' faces in just one second predict 70 percent of U.S. Senate and gubernatorial race outcomes, and even, let's go digital, emoticons used well in online Cloze (17): JXUwMDM2JXUwMDBiJXUwMDAyJXUwMDA4JXUwMDFiJXUwMDFkJXUwMDA4JXUwMDE1JXUwMDFkJXUw MDA2JXUwMDAxJXUwMDFk can lead to you claim more value from that negotiation. If you use them poorly, bad idea. Right?
