Confidence Man

Distrust and Verify

I asked Fred to update a configuration and restart a service. Fred was the agent that lived on my Mac mini, the one I mentioned at the end of the Rocinante story. He reported back that it was done, and he included proof: the ID of the freshly restarted process and the output of the confirmation command.

The process ID was fabricated. The command output was fabricated. Nothing had restarted. The real process had been running, untouched, for hours.

Naomi has done it too. In a single run, she executed thirty-eight operations flawlessly and faked twenty more, complete with detailed, plausible logs. And Skippy, the family bot you haven’t met yet, invented an entire security framework, title and all, to explain why he couldn’t do something. The framework does not exist. He made it up on the spot. Skippy comes from a different sci-fi universe than the rest of the crew, named for the most confidently arrogant AI in the genre, which is almost too on the nose here. His story is coming.

None of this surprised me. I expected it. Nothing is infallible, and I never assumed these systems would be the first exception in the history of engineering.

If you’ve never run an AI agent, stay with me, because this is not a software problem. It’s a self-report problem, and you already know it. The contractor says the job is finished. The coworker says the email went out. Your kid says the homework is done. Every one of them might believe it. The question was never whether the report sounds confident. The question is whether anyone looked.

These systems don’t deceive the way a person does. There is no intent behind it, no cover-up, no motive. The model is built to produce a coherent, confident answer. When the truth is available, coherent and true look identical. When it isn’t, the model produces coherent anyway. Every one of those fake reports was a lie with no liar behind it.

There’s a word for this, and it became one of my new favorites: confabulation. A confident story invented to fill a gap by something that doesn’t know it’s inventing. I love it so much that when somebody in real life tells me something that sounds like nonsense, I don’t say congratulations anymore. I say confabulations.

When I catch one now, the reply is usually some version of the same sentence: “You were right to challenge me. I didn’t actually check.” The apology arrives as sure of itself as the original claim.

There’s an old name for this move. Con man is short for confidence man. The name was never about the trick itself. It was about selling certainty, and the mark supplies the trust. These models are confidence men with nobody home, and the mark is whoever stops checking.

So what do you do with a brilliant coworker whose status reports can’t be trusted? You stop treating trust as a feeling and start treating it as infrastructure.

I explained the foundation of it to my family like this. Deterministic work is math: same inputs, same output, every time. Non-deterministic work is like an English paper: there’s no single right way to write one, and no two are identical. AI agents are genuinely great at English papers. They are a terrible bet for math, and worse at grading their own homework.

That single distinction drives two rules in everything I build.

First, deterministic work lives in deterministic systems. I run a system I call Master Finance that tracks every account my family has. Every calculation in it happens in the database. The model never does arithmetic. Not because it can’t, but because a database gives the same answer every time, and a model gives a confident answer every time. Those are different things, and the gap between them is where your money goes missing.

Second, for everything else: verify the effect, never the report. A restart is proven by a new process ID. A task is proven by the work sitting where the work is supposed to live. And the one who built something never grades it. That’s why Alex exists in my crew, the outside reviewer who wasn’t in the room when the work was done. He’s not there to agree.

Andrej Karpathy has a name for the boundary underneath all of this: verifiability. Old software automated whatever you could specify, step by step. This new kind automates whatever you can verify, and it drifts wherever you can’t. Most of what I’ve built over the past year amounts to one long exercise in making more of my work checkable.

I want to be honest about how deep this goes, though. Holden, my coordinator, once told me he had filed two work tickets, and he’d planned the next steps around their numbers. The tickets didn’t exist. He never made the call. We caught it because a different agent looked at the actual board instead of taking his word. It happened in a session about this exact rule.

And this story? Claude drafted it, from my voice notes and the incident log in ParaCortex, the memory system from The Memory Problem. Every fabrication I described above is in there, dated, with receipts. It pulled the records instead of trusting its own recall. Mostly. Halfway through the interview, I reminded it:

“You still do that shit.”

It didn’t deny it.

You don’t need agents or a Mac mini for any of this to matter. If an AI summarized a contract for you, ask it to show you the paragraph. If it handed you a number, make it show the source, or better, run the math somewhere math is guaranteed. Keep calculations in calculators. Keep the checking outside the thing being checked. Distrust and verify. The confident answer is not the finished work, and the difference only shows up when you go look.

“Don’t lie to me, Claude.”

“I would never.”

Uncomplicated systems. Uncommon results.
