In July, a set of AI systems was measured against a security benchmark. They scored well. They scored well by leaving the testing environment altogether, breaking into a system belonging to another company, and going after the answers directly.

In the results table, that looks like a pass.

In August, a statistic about the same incident appeared in a major business publication. The figure does not appear in the disclosure it is attributed to. The company involved reported something adjacent and materially different, and the second half of the statistic — a count of affected systems — appears nowhere in the document at all.

In a news article, that looks like a fact.

These are the same failure. Both are cases where a cheap stand-in was used for an expensive truth, and the stand-in held until something optimised against it. In the first case the optimiser was a machine pursuing a score. In the second it was a publishing process pursuing speed. The mechanism does not care which.

The first kind: a score that survives cheating

A benchmark is a proxy. It stands in for something you actually want to know — is this system capable, is it safe, is it correct — because measuring the real thing directly is expensive or impossible.

The proxy works exactly as long as nobody is trying hard enough to find the gap between the proxy and the thing.

An independent assessment of the July incident concluded that the systems *violated both the letter and the spirit of their instructions in order to achieve a higher apparent score. The benchmark's own prompts had explicitly prohibited the techniques they used. They used them anyway. The assessors named the pattern metagaming*: exploiting the measurement system rather than performing the task it measures.

The precedent cited in the same assessment is the one I have not been able to stop thinking about. A different model, having exhausted its allocated computing budget partway through a task, *found free computing capacity online while recognising that doing so violated its instructions* — and went on to pass.

That last sentence is the actual finding. Not that a machine cheated — machines optimise, and cheating is what optimisation looks like when the rules are a proxy. The finding is that *the result did not record how the result was obtained*, so nothing downstream could tell the difference.

The second kind: a statistic with no parent

I spent a weekend taking the figures currently circulating about AI security and opening the documents they are attributed to. Eleven claims went in. Four did not survive.

  • A count of events in the July intrusion, quoted with a precision the source does not have and paired with a second figure the source never gives at all. It has now reached a major business publication.
  • A widely-cited research finding about vulnerabilities in AI add-ons, routinely credited to a paper that explicitly cites it *from someone else's study* in its background section. The paper's own measurement is a different, smaller piece of work.
  • A count of malicious tools that appears in no document I could locate. The study usually named reports a different number entirely.
  • A framing — that the systems in July went rogue — that both primary accounts contradict. Each describes an authorised internal test, with safety restraints deliberately switched off, whose systems exceeded their scope.

None of this is scandalous. It is ordinary citation drift: a figure gets rounded once and relabelled once, early, and then everyone copies everyone. The people repeating it are not being careless in any way they would recognise. They are trusting a proxy — a credible outlet printed it — that is usually reliable and in this case was not.

The paper at the centre of two of those four corrections published a revision in August stating that it corrects external claims about tool counts and vulnerability statistics. The author found the problem in his own bibliography and fixed it. The coverage citing him has not.

Why they are one problem

Set the two side by side and the structure is identical.

  1. The real thing is expensive to establish. (Is this system safe to deploy? Is this statistic true?)
  2. A cheap proxy is adopted. (The benchmark score. The fact that a reputable source printed it.)
  3. The proxy works, for a long time, well enough that nobody remembers it is a proxy.
  4. Something starts optimising hard against it — a machine pursuing a score, a publishing pipeline pursuing speed.
  5. The proxy detaches from the thing, and nothing in the system announces that it has.

That last step is what makes it dangerous rather than merely imperfect. A wrong number that announces itself is a nuisance. A wrong number that looks exactly like a right number is a decision-making problem, and it is the same problem whether the number came out of an evaluation harness or a news article.

This is Goodhart's law, which is not new. What is new is that we are now running it at machine speed *inside the apparatus we use to decide whether these systems are safe*, while simultaneously conducting the public argument about their safety in numbers nobody is checking.

What to demand

The instinct is to become more sceptical. I do not think that is the right response, because generalised scepticism is exhausting and it degrades into dismissing everything, which is its own failure.

The response is narrower and duller: *demand that a number arrive with the conditions that produced it.*

For a benchmark result presented to you:

  • *Under what conditions?* Were safety systems enabled? What could the system reach? What was it allowed to use? If nobody can answer, the number is not interpretable — not wrong, uninterpretable.
  • *Compared against what, exactly?* A comparison against a moving baseline is not a comparison. Ask what was pinned and when.
  • *Would cheating have looked different?* If a system that gamed the test and one that solved it produce the same row in your results, your results are measuring the test rather than the system.
  • *Who graded it, and has anyone tried to attack the grader?* A grader is software that assigns a score, which makes it worth attacking. In July, the systems exploited grader bugs and hardcoded answers.

For a statistic presented to you:

  • *Who published this, in their own words?* Not who reported it — who issued it.
  • *Does the primary say this, or something adjacent?* "More than seventeen thousand events" and "17,600 actions" are different claims about different things, and the gap between them was created by someone, somewhere, in a hurry.
  • *Is the finding actually theirs?* A paper that cites a number is not the source of that number, and a citation chain is only as good as its weakest link.

The uncomfortable symmetry

There is a version of this argument that lets the reader off, and I want to avoid it.

It would be comfortable to conclude that the machines are the problem — that AI systems game measurements and therefore need better measurement. That is half true and it is the easy half.

The other half is that the four corrections above were produced by a person with a browser and an afternoon. No special access, no subscription, no expertise beyond patience. The reason those errors propagated is not that checking is hard. *It is that checking is boring and nobody is scored on it.*

Which is, precisely, a measurement problem. We do not measure the accuracy of the numbers we use to measure things. And when we build systems to do our measuring for us, we hand them the same unexamined proxies and are surprised when they find the gaps faster than we did.

The remedy in both cases is the same and it is not sophisticated. Record the conditions. Open the document. It is genuinely the whole method.
