The Body Language Feedback Loop 8:53 Lena: We've talked a lot about what’s happening inside the head and the nervous system, but I want to go back to something you mentioned earlier—how we "signal" our way into confidence. I’ve seen all those "power posing" videos, and I have to admit, standing like Wonder Woman in a bathroom stall feels a little ridiculous. Does it actually do anything?
9:04 Miles: I know, it feels a bit "self-help cliché," doesn't it? But there’s a real neurological principle at play here called "embodied cognition." Your brain takes cues from your body just as much as your body takes cues from your brain. In 2010, researchers at Harvard—including Amy Cuddy—found that holding open, expansive postures for just two minutes could actually shift your hormones. Testosterone, which is associated with confidence and risk tolerance, went up, while cortisol, the stress hormone, went down.
9:34 Lena: Two minutes? That’s it?
9:36 Miles: Just 120 seconds! Now, the specific hormonal numbers have been debated in later studies, but the psychological effect has been replicated over and over. People who take up space—meaning they don't cross their arms, they keep their shoulders back, and their chin up—report feeling more powerful and in control. It’s a "top-down signal reversal." You aren't waiting to feel confident to stand tall; you stand tall to tell your brain, "Hey, we’re safe, we’re in charge."
10:03 Lena: It’s almost like you’re "hacking" the system. If I’m hunched over my phone, my brain thinks I’m in a defensive, submissive state. If I open up, the brain interprets that as a lack of threat.
10:14 Miles: Spot on. And it’s not just about how you feel; it’s about the social feedback loop. People with upright, open posture are perceived as more competent, trustworthy, and attractive within seconds of walking into a room. When people treat you like you’re confident, it becomes much easier to actually "be" confident. It’s that reciprocal relationship again.
10:36 Lena: So, if I’m heading into a tough conversation, instead of just rehearsing my words, I should be rehearsing my "presence."
10:43 Miles: Totally. Think about "Open Body Language." Arms at your sides, feet shoulder-width apart, making natural eye contact. If direct eye contact feels too intense—which is common for people with social anxiety—here’s a little social hack: look at the spot between the other person’s eyebrows. To them, it looks exactly like eye contact, but for you, it takes the pressure off.
11:06 Lena: That is a great tip! I’ve definitely felt that "staring contest" anxiety before. What about the way we speak? I know when I’m nervous, my voice goes up about an octave and I start talking like I’m in a race.
11:18 Miles: That’s the "vocal tone" trap. Speaking too quickly signals to others—and your own brain—that you’re rushing because you don't think your words are worth the time. Confident speech is about the "pause." It’s having the courage to let a moment of silence hang without feeling the need to fill it with "um" or "uh."
11:37 Lena: The "comfortable silence." That sounds like the ultimate level-up.
11:41 Miles: It really is. And try to speak from your diaphragm rather than your throat. It gives your voice a lower, steadier pitch that naturally conveys authority. Again, this is a physical adjustment that feeds back into your nervous system. You’re using your body as a tool to regulate your mind.
11:58 Lena: It’s interesting how all these pieces—the self-efficacy, the cognitive reframing, and the body language—all point toward the same thing: taking an active role in how we perceive ourselves. It’s moving from being a passenger in our own minds to being the driver.
12:14 Miles: That’s the perfect analogy. And as the driver, you need a "Social Confidence Toolkit." You need strategies for when things get awkward. Because let’s be honest—they will! Even the most confident people have moments where they forget a name or trip over their words. The difference is how they handle the "recovery."
12:32 Lena: Right, because if you’re a "Perfectionist" type, a single awkward moment feels like evidence that you should just go home and hide under a blanket for a week.
0:31 Miles: Exactly. But social confidence isn't the absence of awkwardness; it’s the ability to recover gracefully. If you forget a name, just say, "I’m drawing a blank on your name—could you remind me?" Most people actually appreciate the honesty. It shows you’re human and that you’re comfortable enough with yourself to admit a tiny mistake.
