Jackson: You mentioned the limbic system earlier, and it got me thinking. We like to think we’re these highly evolved, rational creatures, but when things get tense, we’re basically just hairless apes, aren’t we?
Miles: Honestly, Jackson, we’re even more primitive than that. Joe Navarro talks a lot about our "Limbic Legacy." Our brains are still running on software designed for the savannah. When we sense a threat—even a social threat like a bad performance review or an awkward date—our brain doesn't distinguish it from a lion in the bushes. It triggers the classic "Freeze, Flight, or Fight" response in that exact order.
Jackson: Wait, I always heard it was "Fight or Flight." You’re saying "Freeze" comes first?
Miles: Absolutely. Think about it—if a predator sees you, the best thing you can do is stop moving. In a modern office, this looks like the "momentary freeze." You ask someone a question they didn't expect, and for a split second, they turn into a statue. Their breathing shallowly stops. That’s the limbic system trying to "hide" from the question.
Jackson: I’ve definitely seen that! It’s that awkward beat before they start talking. And what about "Flight"? I can’t exactly run out of a conference room.
Miles: Right, so we do "distancing behaviors" instead. We lean back in our chairs. We point our feet toward the door—which is a huge tell, by the way. Or we create "eye blocking" or "torso shields." You might see someone suddenly zip up their jacket or put a coffee mug between you and them. They’re literally creating a barrier because their brain wants to get away.
Jackson: It’s wild that we’re doing this without even knowing it. It’s like the body is trying to protect the "vital organs" from a verbal attack.
Miles: Precisely. The torso houses all your soft, vulnerable bits. When we feel safe, we do "ventral fronting"—we turn our front toward the person. When we feel threatened, we turn slightly away, protecting the midline. It’s a survival reflex.
Jackson: And "Fight"? I’m guessing that’s not just throwing punches in the breakroom.
Miles: Usually, it’s "territorial displays." Puffing out the chest, putting hands on hips—the "superman" pose—or even just spreading your stuff out all over a table to take up more space. It’s an assertion of dominance. But here’s the cool part: once the "threat" passes, the limbic system needs to calm itself down. That’s where "pacifiers" come in.
Jackson: Pacifiers? Like for babies?
Miles: Exactly like that. Adults just have different versions. We rub our necks, we stroke our hair, we massage our earlobes, or we clear our throats. These are self-soothing behaviors. When we touch these areas—especially the neck, which is rich in nerves—it actually lowers our heart rate.
Jackson: So if I see someone rubbing the back of their neck after I give them feedback, they’re literally trying to physically calm their own nervous system down?
Miles: Yes! And that’s such a powerful insight for a leader or a friend. Instead of thinking, "Oh, they’re being weird," you can think, "Okay, their stress level just spiked. I need to slow down and create some safety here."
Jackson: That changes everything. It turns "reading people" into an act of empathy. You’re not "catching" them; you’re understanding their internal weather.
Miles: That’s the goal. If you see a pacifier, don't call it out—that’ll just make it worse. Instead, address the discomfort. Ask a diagnostic question like, "It seems like this part is a bit complicated—what are your thoughts on it?" You’re giving them a "verbal bridge" to come back to comfort.
Jackson: So the lesson here is: watch for the Freeze, the Distance, and the Pacifier. If you see those, you know the limbic system is in the driver’s seat.
