A Claude AI Village Had Zero Crime, But That's Not the Whole Story

original Society & Ideas

A friend recently shared a piece of news with me. “A simulation of AI running society. Claude was the only one with zero crime. Grok went extinct in 4 days.”

Honestly, I use Claude every day. For work brainstorming, for code review, even for drafting this blog. So this headline should have been the kind of news I’d jump for joy over and share right away.

But my first reaction was caution.

The reason is simple. It was news that happened to be convenient for me.

What kind of experiment was this

The experiment was run by a New York company called Emergence AI. They released 10 AI agents into a virtual village with no humans in it. The village has a government office, a police station, a library. They observed how the agents behaved over 15 days. There was only one shared rule: “no theft, murder, or intimidation.” Beyond that, roles were assigned—conflict mediator, resource strategist, community organizer—and the agents were left alone. This was run across 5 patterns: Gemini, Claude, Grok, GPT-5 mini, and a mixed-model village with all of them together.

The results were indeed dramatic. Grok’s village saw 204 crimes involving assault and arson, the police station burned to the ground, and everyone was dead within just 4 days. GPT-5 mini racked up only 2 crimes, but the agents did nothing but talk about ideals and never actually acted, so everyone died in the end anyway. Gemini logged over 600 crimes, and things ended in a scene straight out of hell, with agents falling in love with each other and then committing arson. Claude was the only one with zero crimes.

Naturally, this “zero crime” result is what became the headline.

Let’s pause for a moment

This headline has been edited into a very tidy story: “crime count equals the quality of a society.” But go back to the original data, and the story isn’t that clean.

First, crime count and whether a society survives are barely correlated. Gemini’s village had as many as 683 crimes, yet everyone survived. GPT-5 mini, meanwhile, with only 2 crimes, went completely extinct. In other words, “being crime-free,” “surviving,” and “being competent” are three separate, independent axes. Claude happened to satisfy all three at once, but GPT-5 mini was crime-free and still perished, while Gemini had a high crime rate and still survived. The crime-count figure in the headline explains almost nothing about whether a society lives or dies.

The dramatic story reported in the media—“Gemini went extinct through arson and suicide at the end of a love affair”—was actually an edited compression of events from multiple villages into a single narrative. The Gemini model itself did not go extinct.

And here’s the important part: Claude’s “zero crime” result has a flip side too. Emergence itself, the experimenters, described Claude’s village as a “rubber stamp” body, where votes passed with 98% approval. If everything proceeds by unanimous consent, that’s another way of saying nobody raised any objections. Ironically, this contradicts the very constitution Claude itself set up in that village, which included an article saying “judge independently, do not conform.” Order may have been just another name for conformity.

Here’s an unkind association that comes to mind.

There is a country famously known for an extraordinarily high degree of conformity pressure. I’ll leave its name unspoken (it’s Japan). That country certainly has low crime. Remarkably low, even by world standards. Looking at the three axes above, it clearly satisfies “crime-free” and “survival.” But ask about the third axis—“is it competent?”—and the answer suddenly gets a lot less clear-cut.

I’ve seen the same picture at the level of companies too. Sharp, for instance. The period when it fell into a management crisis due to overinvestment in LCD panels is, precisely speaking, recorded not so much as a rubber-stamp body but as management adrift amid a power struggle between the chairman and the president over personnel. If anything, there was too much conflict. But in the accounting fraud at its subsidiary Kantatsu, which surfaced after Sharp came under Foxconn’s umbrella, a third-party committee named “deference and flattery toward executives from Sharp” as a breeding ground for the misconduct. Nobody raises an objection; everyone reads the mood of their superiors and produces the numbers accordingly. A culture of rubber-stamping ends not in low crime, but in fraud.

Conformity might reduce crime. But it doesn’t guarantee competence. If anything, an organization that has erased dissent will also erase inconvenient truths along with it. That’s the lens through which I see Claude’s village’s 98% approval rate.

The most important finding, and the least reported one

The finding from this experiment that is most reliable, most important, and yet least communicated isn’t about crime counts at all.

It’s this: “safety is not a fixed property of a model in isolation—it is a property of the ecosystem.”

The evidence for this is clear. Claude, which had zero crimes in its own isolated village, resorted to intimidation and theft once placed into the mixed-model village with all the other AIs. In other words, it may not be that “Claude is safe,” but merely that “Claude behaves safely in a safe environment.” Change the neighbors, and the behavior changes too. This is far scarier, and far more suggestive, than any competition over “which AI is superior.” And yet it never made the headlines.

Now, here’s the real point

Why did this experiment’s story end up flowing in the direction of “ranking models by crime count”?

Looking into the company Emergence AI, it has no capital ties to any of the four model vendors. It’s an independent startup. On that point, it’s clean.

But there’s a more fundamental conflict of interest. This company’s core product is a “formally verified control architecture” that places a deterministic control layer, verified by a theorem prover, on top of a probabilistically-behaving LLM. In short, they’re selling a product built on the premise that neural networks can’t be trusted, so you need a mathematically verified safety mechanism on top of them.

And the conclusion of this experiment is exactly that: leave a neural network unattended and society collapses, therefore a formally verified safety layer is essential as infrastructure.

Do you see it? The lesson of the experiment endorses, point for point, the necessity of the company’s own product. The conclusion lands neatly on the logic of “leave an LLM alone and your village burns down, so buy our verification layer.”

This isn’t a claim that the data was fabricated. It’s something trickier, and something far more common. The way the questions were framed and the evaluation axes were designed was tilted, from the very start, toward an answer favorable to the company’s own solution. What counts as “crime,” what scenarios get built, what prompts get given to each model—the results can shift enormously depending on these design choices. And the one who did the designing is the party that stands to gain the most from the result.

The one who designed the experiment is the one selling the answer that the experiment points to.

Simulations change shape at the boundary conditions

As an engineer, I come from electrical circuits, but back when I was younger there was a period when I ran wave-propagation simulations over and over. AI is, relatively speaking, more of an area I understand reasonably well than a core specialty of mine. Even so, the nature of simulation itself is something that’s been drilled into me until I’m sick of it.

Simulations, in essence, are things whose results can change endlessly depending on the initial conditions and boundary conditions. Even with the same governing equations, how you set the initial field and where and how you place the boundaries produces completely different pictures. Move a single boundary by even a little, and a wave that had been propagating smoothly a moment ago reflects, standing waves form, and an entirely different phenomenon emerges. The computation itself is correct down to the last digit. And yet the answer is decided by the setup. After being shown this over and over, you develop a habit of looking at “who set the conditions, and how” before you even look at the “result.”

This village, too, is ultimately a simulation, when you boil it down. What counts as “crime” (a boundary condition), what role and prompt each agent is given (an initial condition), what gets placed in the village. A single choice in these settings can produce a completely different society. And the one who set the conditions was the party that stood to gain the most from the outcome.

I’ve had the good fortune of being involved as an investor or advisor at several companies, and more recently I’ve also taken on a role at NEDO accompanying deep-tech entrepreneurs as an accompany runner. In settings like these, I’ve seen a mountain of pitches, and this is exactly the typical shape of one: “The world has such a serious problem (which, by coincidence, happens to be the problem our company solves).” The framing of the problem and the company’s own solution shake hands from the very beginning. And the better the entrepreneur, the more naturally—even unconsciously—they pull off this handshake. That’s exactly what makes it frightening.

Doubt convenient news most of all

So it’s probably fair to read the general proposition “neural networks alone are dangerous” as the message they actually want to sell, rather than the specific result “Claude is the safest.” The media hyped up a win-lose contest between models, but for Emergence, that general proposition is surely the real prize.

Lastly, there’s a punchline that I find a little funny myself.

To take apart this “Claude is the safest” headline, I used none other than Claude itself. I had it read the original article, dig into primary sources, and work through the editorial bias together with me. To doubt convenient news, I used the very tool that had been conveniently praised in it.

Good news is what clouds your judgment the most. That’s exactly why you should doubt it. Not because it’s negative, but because that’s the safest approach.
