You’ve seen the videos. A guy in a sharp suit sits across from a camera, watching a clip of a celebrity or a politician, and starts dissecting why a tiny twitch of their eyebrow means they’re lying through their teeth. Most of the time, that’s just entertainment. It’s what Joe Navarro calls "body language junk science."
But Joe isn't some YouTube "expert" who read a blog post and decided to start a channel. He’s the real deal. We’re talking about a man who spent 25 years in the FBI as a counterintelligence special agent. He didn't just study people; he caught spies. And his book, What Every Body Is Saying, has basically become the Bible for anyone trying to figure out what’s actually going on in a room when nobody is talking.
People are still obsessed with this book years after it came out. Why? Because honestly, most of us feel like we’re missing a secret frequency. We want to know if the person we’re dating is actually into us, or if our boss is about to fire us, or if the guy selling us a used car is full of it.
The "Honest" Brain vs. The "Lying" Brain
The core of what Joe Navarro teaches—and what everybody is saying about his method—revolves around a specific part of your head: the limbic system.
Navarro calls this the "honest brain." Think of it as your internal survival hardware. When a tiger jumped out at your ancestors, they didn't stop to write a pros and cons list. They reacted. That system is still there, and it controls your nonverbal responses.
The neocortex, on the other hand? That’s your "thinking brain." It’s the part that lets you do math, write poetry, and—this is the big one—lie. You can tell a lie with your mouth, but it is incredibly hard to tell a lie with your feet.

That’s actually one of the most famous takeaways from What Every Body Is Saying. Most people focus on the face because that’s where we look. But Joe argues the face is the most deceptive part of the body. We’ve been taught to smile when we’re unhappy since we were toddlers. But our feet? We almost never think about them.
If you’re talking to someone and their torso is facing you, but their feet are pointed toward the exit, they want to leave. Period. Their limbic brain is already plotting the escape route.
Stop Looking for the "Lie Signal"
Here is the biggest misconception about Joe Navarro’s work: people think he’s giving them a "Pinocchio’s nose" guide.
"If they touch their nose, they’re lying."
"If they look to the left, they’re making it up."
Actually, Joe says that’s total nonsense. In fact, he’s been pretty vocal about how humans are generally lousy at detecting deception. Even the pros. What you’re actually looking for isn't "the lie." You’re looking for discomfort.

When someone is stressed, they do what Joe calls "pacifying behaviors." These are self-soothing actions that stimulate nerve endings to calm the brain down.
- Neck touching: Especially the little notch at the base of the neck (the suprasternal notch).
- Leg rubbing: Often called "leg cleansing," where someone rubs their palms down their thighs.
- Ventilating: Pulling at a shirt collar or moving hair away from the neck.
If you ask someone a question and they suddenly start stroking their neck, it doesn't mean they’re a Russian spy. It just means the question made them uncomfortable. The trick is connecting the behavior to the stimulus.
The Importance of the Baseline
You can’t just walk into a coffee shop and start diagnosing people. Well, you can, but you’ll probably be wrong.
To really use the techniques in What Every Body Is Saying, you have to establish a baseline. How does this person act when they’re relaxed? Do they naturally fidget? Do they usually sit with their legs crossed?
If your friend is a habitual nail-biter, seeing them bite their nails doesn't mean anything. But if they are normally as still as a statue and suddenly start drumming their fingers when you mention a specific name, that is a shift. That’s the "tell."

We live in a world where so much of our communication is digital, but when we finally get face-to-face, the stakes feel higher. Whether it’s a high-stakes business negotiation or a first date, understanding nonverbals is like having a superpower.
It’s not about "catching" people. It’s about empathy.
Joe often talks about how "exceptional" people are hyper-attentive. They aren't just looking for lies; they’re looking for how people feel. If you notice your partner is showing "gravity-defying" gestures—like their toes pointing up or a bit of a bounce in their step—you know they’re genuinely happy. If you see their lips compress into a thin line (lip disappearance), you know they’re processing something negative before they even say a word.
Actionable Next Steps to Master Nonverbals
If you want to move beyond just reading about Joe Navarro and actually start seeing the world differently, here’s how to do it without being creepy:
- Start with the Feet: Next time you’re in a meeting or a social gathering, look under the table. Are feet pointed toward the speaker? Is someone’s foot "kicking" (a sign of excitement or agitation)?
- Identify Three Pacifiers: Watch a talk show or a long-form interview on YouTube. Try to spot when the guest touches their neck, adjusts their jewelry, or exhales with puffed-out cheeks. Note what was asked right before they did it.
- Practice "The Tilt": In your next conversation, consciously tilt your head slightly to the side while listening. It’s a powerful "comfort" signal that shows you’re actually listening and not just waiting for your turn to talk.
- Observe the "Ventral Side": We protect our front (ventral) when we feel threatened. If someone suddenly crosses their arms or holds a coffee cup like a shield in front of their chest, they’ve shifted from comfort to discomfort.
Mastering these nonverbals isn't about manipulation. It's about becoming a better observer of the human condition. When you understand What Every Body Is Saying, the world gets a lot quieter, because you realize people have been screaming their truths all along—just not with their voices.
