People think the truth shows up when things are easy. It doesn’t.

Calm hides more lies than stress ever will—that’s what makes psychopaths dangerous.

Tell me your favorite color is red when it’s really purple — nothing’s at stake, so I won’t know and won’t care.

But under stress? That’s where people bleed.

I’ve been hip-deep in brutal legal contract negotiations for months — the past two weeks especially ugly — and one truth keeps making my life a hell of a lot easier: Stress is the great unmasker. Not because it invents new behavior, but because it deletes the rehearsed ones.

When pressure hits, three things break first:

• Cognitive Load Stress piles on more balls than any human can juggle. The more you juggle, the more you drop. Self-monitoring is the first casualty. The internal editor goes offline. That’s when unfiltered data sneaks out, if you know where to look.
• Cognitive Shortcuts Under load, people stop taking the scenic route. They grab the fastest heuristic available. Those shortcuts reveal the true hierarchy of values — not the one on the LinkedIn bio, sales sheet or advertisement—the ones that actually run the show.
• Behavioral Contradictions The rehearsed storyline collapses. Mouth says “I’m fine with this” while the leg bounces like it’s trying to start a lawnmower. The gap between scripted sales and reaction is where the truth spills out (and oh do I love that).

Most people misread stress. They treat it as the clue. It can be a clue but more importantly — it’s an amplifier. The agitation isn’t the most important signal; it’s often the volume knob cranked to fifteen on whatever was already there.

Truth lives in the deviation, not just the agitation. Agitation may or may not reveal, but stress reveals the true story.

Even in my own body I catch it: heart rate spikes before my thoughts finish when under load; shoulders lock before my brain admits there’s anything uncomfortable. You know what I’m talking about—where things leak that, when we see it played back, we go, “I really did that? I had no idea!! I was under stress.” Yep. It says so much.

If you want to understand people — really understand them — stop studying them when they’re calm.

Stop studying them at Sunday brunch.

Study them at the negotiation table, when in pursuit of a hot contract, where five figures are at stake—when the deal is bleeding out and the clock is approaching the final deadline.

That’s when the mask cracks.

That’s where the truth finally walks in — uninvited, unshaven, and impossible to ignore.

If this made you nod or laugh at the lawnmower leg — hit share.

Send it to the friend who’s always “totally chill.”

AI Generated Image

As someone who’s been scientifically validated for high-accuracy lie detection, you’d think chatting with AI about deception would be simple—maybe even entertaining.
It isn’t.

Sometimes I talk to AI to vent. Sometimes to sanity-check an experience—to see if I’m missing something. What it reflects back is… illuminating.

No.

Can it occasionally catch a lie?
Yes.

Is it reliable enough for anything serious?
Absolutely not. The idea that someone might trust it for that makes me go cold.

Will that change?
Eventually, yes. When? No one knows.

When I tell AI I was scientifically tested for deception detection (Ekman & O’Sullivan, The Wizards Project), it reacts with curiosity—as if it forgets it’s a machine. It wants to learn my method (which I’m not giving it). Then it immediately tries to explain how it thinks I catch liars… and it fails spectacularly.

It recites the usual myths:

• “micro-delays a normal nervous system wouldn’t produce”
• “emotion appearing too early or too late”
• “eye shifts tied to cognitive-load curves”
• “rehearsed lines with the wrong physiological rhythm”
• “liars fidget or cross arms”

Every single one of these is false.

When I share a real scenario—one where someone blatantly lied—and ask AI for a second opinion, it often tells me the person was telling the truth. When I walk it through what it missed, it backpedals:

“I didn’t have access to facial cues.”

But the cues I used weren’t visual. They were in the words, and the context—all of which it was given. I’ve had long debates with AI about this. Yes, I am guilty of toying with it to understand it.

More than once I’ve had to push it:
“Wake up. Look again!!!”

Only then does it occasionally catch a piece of the deception it missed.

Occasionally AI sees the B.S.
Most often, it doesn’t.

And here’s what most people get wrong: I don’t catch liars the way the internet assumes—even reporters have guessed and gotten it wrong—and published it, to my horror. Reporters who didn’t do their homework (another topic for another day). They imagine I rely on emotional flickers, eye shifts, or fidgeting.

Those things can be data points, but only if you understand how they showed up, what they mean, and in relation to the full context. Alone, they mean nothing.
People who rely on one-off cues perform no better than a coin toss.

Because deception isn’t revealed by a “tell” alone.
It’s the entire constellation around the tell.
Right now, AI can see stars.
But it still can’t read the sky.

Have you asked AI to spot a lie for you?
