A few years ago, someone came up to me after a keynote and asked a question I’ve heard countless times over the years.
“So… can you actually tell what people are thinking just by looking at them?”
I understood why they were asking. We live in a world filled with television shows, viral videos, and internet “experts” who make human behavior sound like a secret code waiting to be cracked. Scratch your nose and you’re lying. Cross your arms and you’re defensive. Look away for half a second and suddenly someone claims they can see directly into your soul.
It’s fascinating. It’s also wildly oversimplified.
Part of the confusion comes from entertainment itself. As a mentalist, I understand the appeal of creating the illusion of extraordinary perception. In fact, a large part of what I do on stage is illusion. Mentalism is designed to create the feeling that impossible things are happening. That mystery is intentional. It captures attention, sparks curiosity, and invites people into the experience.
But entertainment and real-world communication are not the same thing.
I cannot look at someone’s posture and determine their mother’s maiden name. Human beings are not puzzles waiting to be solved through a handful of gestures. And despite what some online body language content suggests, real nonverbal communication is far more nuanced and far more human than that.
Ironically, my deeper expertise in communication did not come from mentalism at all. It came from theater.
As a PhD candidate studying theatrical movement, I spent years immersed in academic research surrounding physical expression, movement psychology, audience response, and nonverbal communication, I was reading scholarly work about how people communicate emotion, status, engagement, tension, trust, and connection through behavior and interaction.
The deeper I went into the research, the more obvious something became:
Body language is not about mind reading. It is about awareness.
That distinction changes everything.
Why People Are So Fascinated by Body Language
I think people are drawn to body language because communication often feels uncertain. We all want clarity. We want confidence. We want to believe there are shortcuts that allow us to instantly understand what other people are thinking or feeling.
That’s why simplistic advice spreads so easily online.
“If someone crosses their arms, they’re closed off.”
“If they touch their face, they’re nervous.”
“If they avoid eye contact, they’re lying.”
The reality is much more complicated.
Someone might cross their arms because they’re cold, comfortable, skeptical, thoughtful, or simply standing the way they always stand. A single gesture rarely tells the whole story. Without context, most isolated body language interpretations become guesswork disguised as certainty.
Real nonverbal communication involves patterns, timing, clusters of behavior, environmental context, baseline personality, and interaction. It is dynamic, not mechanical.
Human beings are not machines producing fixed outputs.
What Body Language Can Actually Tell You
Now, with all of that said, body language absolutely matters.
In fact, it matters enormously.
But probably not in the way most people imagine.
What body language often reveals is not hidden secrets, but emotional direction. It gives us clues about:
– engagement
– comfort
– skepticism
– tension
– openness
– hesitation
– confidence
– uncertainty
When I’m speaking to an audience, I’m constantly paying attention to these signals. Not because I’m trying to “read minds,” but because I’m trying to understand the relationship between myself and the audience in real time.
Are they leaning in or checking out?
Are they engaged or skeptical?
Do they trust me yet?
Are they comfortable enough to participate?
That feedback changes how I communicate. It influences pacing, tone, storytelling, interaction, humor, and energy. The audience is constantly communicating back to me, even when nobody is speaking.
That’s the real value of nonverbal communication. It helps us adjust, connect, and communicate more effectively.
The Illusion and the Reality
One of the interesting tensions in my work is that I live in two worlds at once.
As a mentalist, part of my job is creating illusion. The performance creates the feeling that impossible things are happening. That sense of wonder disarms people in the best possible way. It lowers defenses. It captures imagination. It creates curiosity.
And curiosity is powerful.
Because once people become curious, they become open.
That’s where the deeper communication lessons begin.
The real goal of my work is not convincing audiences that I possess supernatural abilities or some magical power to decode human beings. The goal is helping people become more aware of the signals we all send and receive every day.
I want audiences to think differently about:
– engagement
– attention
– trust
– perception
– skepticism
– connection
Those things genuinely shape leadership, relationships, teamwork, and communication.
The illusion opens the door. The real lessons happen afterward.
The Biggest Mistake People Make
One of the biggest mistakes people make is treating body language like a decoding system instead of a communication system.
Two people can display the exact same gesture for entirely different reasons. That’s why context matters so much.
A crossed-arm posture during a difficult negotiation may communicate something very different than crossed arms during a relaxed presentation. A lack of eye contact may indicate discomfort in one situation and cultural respect in another.
The danger of oversimplified body language advice is that it creates false confidence. People begin assuming they understand others far more than they actually do.
In my experience, the strongest communicators tend to become less certain, not more certain. They stay curious. They observe patterns. They pay attention to feedback. They adapt.
What I Actually Look For
Whether I’m delivering a keynote, leading a workshop, or performing mentalism, I’m rarely looking for one isolated gesture.
I’m looking for patterns of response.
I pay attention to:
– shifts in energy
– facial responsiveness
– posture changes over time
– participation levels
– audience synchronization
– reactions to certain stories or ideas
Most importantly, I pay attention to congruence.
Does someone’s verbal communication align with their nonverbal communication?
Even then, I try to avoid rigid assumptions. Nonverbal communication is not a crystal ball. It is feedback.
And that perspective becomes incredibly useful for leaders, sales professionals, speakers, and anyone trying to communicate more effectively.
What Leaders Often Miss
One of the central ideas in my Signals for Success keynote is that communication is not just about the message being delivered. It’s about the message being received.
Many leaders focus entirely on what they want to say.
Strong communicators pay attention to how people are responding while they say it.
That subtle shift changes conversations dramatically.
Great communicators notice:
– when engagement drops
– when tension increases
– when trust begins forming
– when people become more open
– when energy changes in the room
And then they adapt.
That adaptability is often far more valuable than trying to “analyze” people.
The Real Goal of Reading Body Language
I think the healthiest way to think about body language is this:
The goal is not to control people.
The goal is to understand connection more clearly.
When used responsibly, nonverbal awareness helps us:
– become better listeners
– communicate more empathetically
– recognize discomfort
– build stronger trust
– engage audiences more effectively
That is very different from pretending human beings can be reduced to a collection of secret tells.
Ironically, the more seriously you study communication, the less interested you become in simplistic answers. You stop looking for magic formulas and start paying closer attention to nuance, context, and human interaction.
And honestly, I think that makes communication far more interesting.
Because real communication is not about solving people.
It’s about understanding them better.
