The body tells a story.

Sure, that thing between your ears up there gets most of the focus, but what someone does with their body while communicating and interacting with others, one could argue, is almost as important.

The problem is, we’re often expressing a lack of confidence or uncertainty through our posture and other physical positions without ever noticing it. This doesn’t just make us feel less confident, others pick up on these visual cues automatically without noticing it (we all do), so it affects the entire dynamic of a conversation.

Sometimes, this doesn’t matter. Other times, we’re sitting across a potential employer and our body language could mean the difference between walking or getting the job.

The 10 Steps to Confidence That No One Told You About

Body language is a very powerful tool. We had body language before we had speech, and apparently, 80% of what you understand in a conversation is read through the body, not the words.

– Deborah Bull

In her inspiring, and now famous, 2012 TED talk, Harvard professor Amy Cuddy taught us all about the power of body language.

As a professor of diversity at one of the most prestigious business schools in the world, Cuddy became fascinated with power dynamics and eventually began to research the effects of “non-verbal communication” as it related to that dynamic.

In the animal kingdom, the effect of body language can be observed in many animals. In particular, a feeling of power and dominance tends to make us expand and open up our bodies (think raising the arms, spreading the shoulders, leaning back), while a feeling of inferiority, vulnerability, or a lack of confidence causes us to close up (think hunching over, arms curled up, hands on our neck or face).

As humans, we do the same thing. And these displays of body language affect those around us. But this has been known for some time.

In a study published by Alex Todorov at Princeton University, it was shown that judgments of political candidates’ faces in just one second predicted 70 percent of U.S. Senate and gubernatorial race outcomes.

But what Cuddy sought to find out is if these displays of body language affected our own state of mind. For example, if we expand and take up more space do we become more confident simply by taking a new posture– even if we don’t at first feel more confident?

Surprisingly, the answer was yes.

Using body language to unlock your hidden confidence

In her research, and the research of several of her colleagues, Cuddy found that we can, in fact, affect our own state of mind by adopting a new physical posture and position.

In several studies, one which attempted to gauge testosterone and cortisol difference in those who adopted certain postures before and after spitting into a vial (both chemicals linked to changes in posture and feelings of power), and a second where they simulated a very difficult job interview in which the interviewee was given a blank, unemotional stare to intentionally cause social anxiety– the results were the same.

Those who adopted more powerful postures as they were called were noticeably different from those who adopted less confident poses. Those who adopted powerful postures and body positions were far more confident in their performance and the estimated outcome– even if they didn’t start out feeling that way. And the exact same was true of those who adopted vulnerable, less confident poses, even if they started out feeling confident. It turns out, our body language doesn’t just affect those around us, it also affects how we feel about ourselves.

So, how do you use this to your advantage? There are a few very simple practices you can adopt when in a situation that calls for a little more confidence or certainty:

  1. Adopt a power pose: A power pose involves standing in a way that makes you feel more confident. For example, standing, shoulders on your waist like a superhero or pumping your fists for even two minutes has been shown to make a considerable difference. Do this in a restroom or your car alone before entering the social event.
  2. Sit up and spread out: When in conversation, don’t curl up. Adopt a strong posture by sitting up straight and spreading out your shoulders. Place your hands on your thighs or hold them up and together as opposed to on your lap, arms, or neck.
  3. Use your hands when you speak: Hand gestures help us communicate better and they also help us spread out when we’re communicating, further communicating confidence both to ourselves and others.

Body language is powerful, both for communicating confidence to others as well as for making us feel confident in ourselves. No matter what practice you adopt for communicating confidence through your body language, use this information to your advantage on your next date, job interview, or important meet up to inject yourself with a dose of confidence and communicate that confidence to others around you.
