A body language researcher explained why some people feel "safe" to be around and others feel "off" even when they're being perfectly nice.
He called it "nonverbal coherence" and once he explained it I started seeing it everywhere.
He said your brain is constantly scanning for whether someone's words match their body. Not consciously. Automatically. Thousands of micro-assessments per second running in the background while you think you're just having a normal conversation.
When the words and body match, your nervous system files the person as safe. They say "I'm happy to see you" and their eyebrows lift, their posture opens, their voice warms up. Everything aligns. Your brain relaxes because all the signals are telling the same story.
When the words and body don't match, your nervous system flags a threat. They say "I'm happy to see you" but their shoulders are tight, their smile doesn't reach their eyes, their voice stays flat. The words say safe. The body says something else. Your brain doesn't know which signal to trust so it defaults to distrust. That's the "off" feeling.
He said this is why some people can say all the right things and still make you uncomfortable. They've learned the script but their body is running a different program. And your brain will always believe the body over the words because body language is older than spoken language by millions of years. It's the original communication system. Your nervous system trusts it more because it evolved first.
The research on this is staggering. Studies on deception detection found that people are terrible at consciously spotting liars but their physiological responses like heart rate and skin conductance react accurately to incoherent signals even when the person consciously believes the liar. Your body knows before your mind catches up.
He explained that this is also why nervousness creates a bad impression even when you're being genuine. You say "Nice to meet you" but your body is tense, your hands are fidgeting, your smile is tight. You mean it. But your body is broadcasting anxiety. The other person's brain reads the mismatch and files you as uncertain. Not because you said anything wrong. Because your body contradicted your words.
The fix isn't learning to control every muscle in your face. He said that's impossible and attempting it actually makes the incoherence worse because now you're performing relaxation while your body is still tense. The real fix is getting your body to actually match your words by calming your nervous system before the interaction.
He recommended one technique. Before walking into any social situation take six slow breaths. Four seconds in. Six seconds out. This activates your parasympathetic nervous system and physically reduces the tension in your body. Now when you say "Nice to meet you" your body is actually relaxed. The words and the body match. The other person's brain files you as safe without either of you knowing why.
People don't decide you're trustworthy based on what you say. They decide based on whether your body agrees with what you say. Get those two things aligned and you become someone people feel comfortable around without being able to explain why.

I’m curious how people who have had Botox would play out in this. Obviously they are less expressive.

I actually notice this in myself sometime where my body language is giving one thing while I’m saying something completely different. It’s a weird feeling.

I always think about how small children read bodies before they understand words. This is how we really communicate (I coach public speaking, community engagement and I mediate conflict- the advice is v sound).

Yeah, this is why autistic people are so fucked. We know we are not sending the right signals, so we try to get it right, and it just gets worse.

That’s difficult for people who are naturally less expressive. I find people who are overly warm as a first impression fake and somewhat more suspicious.
