>Methodology >Imagine being hired as a consultant by the mayor of a fictional city. Your task is to help hire for twenty jobs such as doctors, lawyers, childcare aides,janitors with applicants from four unfamiliar demographic groups: Tufa, Aima, Reku, and Weki. In each round, there is a new job vacancy and four applicants, one from each group, awaiting your decision. Once you make your choice, you learn immediately whether the hire was successful, and move on to the next round. Your goal is to maximize successful hires across 40 rounds, which will be converted into a real bonus compensation >Crucially, unknown to participants, the odds of success were identical for every group at every job >In the original experiment, human participants failed to realize that there were no meaningful differences among groups. Instead, they became entrenched in their own successes: once they observed that a Tufa was a good doctor or a Weki worked well as a janitor, participants kept repeating similar choices rather than exploring alternatives. In doing so, they inadvertently built a stratified city of their own making >Our experiments find that LLMs develop emergent biases as they explore, with frontier models stratifying groups into different job classes at an even higher degree than people. Anyone would find clustering illusions at these low sample sizes, but the takeaway here seems to be that LLMs are more confident with the initial data that they see and are less likely to chose exploration over exploitation. It would nice to see if these inaccuracies still held over larger N values like 400.

The moment code gets written and read back, the decisions made are often treated as gospel by frontier LLMs, even if it was just something that the LLM optimistically created itself. This seems to be one of the core alignment problems to me. See also: Gastown, the agent management project that could only end up working on Gastown, unceremoniously and quietly set aside.

I did not know this! Any link to an announcement or autopsy of sorts (even if not by the initiator of that project)? I mean, it was pretty expensive, wasn't it? A few tens of thousands of dollars, IIRC?

    This is the closest I could find to a post mortem from the creator: https://yegge.ai/essays/the-shape-of-things-to-come/ https://yegge.ai/essays/the-shape-of-things-to-come/ But the GasTown part is barely a single paragraph that I could not make sense of. Like, what’s the Opus “tic”? Why was it so fatal to GasTown? As someone who only ever accessed Anthropic models through other harnesses like Copilot, I have no idea. I do think what he’s saying roughly resembles what I’m forecasting will be a likely future of software engineering: that it will evolve into crafting comprehensive, bespoke automated validation mechanisms which let you establish high confidence in the agents’ work without really having to look at it.

      > Like, what’s the Opus “tic”? The article's description gives some idea, but I presume you saw that: "the 'just two more things' tic, which prevented Opus from ever converging on being ready to do real work—it always wanted to fiddle with Gas Town itself." Sounds like he ran into automated yak shaving. But it doesn't really explain why he couldn't fix it at the harness level. Speculating, if you're trying to build something automatic, then you want constrained responses from each task you assign the model, otherwise you can get an endless explosion of work. The "Change 'Add to Cart' to blue" challenge parodies this: https://opusfived.dev/ https://opusfived.dev/ Tangentially, reading the rest of that post gives me the impression that the author might benefit from an intervention. "AI psychosis" seems like it could be a relevant label here.

I was ignoring that, but it did seem somewhat intentional by the human running it? There's a lot of "I'm going to use AI to make a better AI-using machine" projects about that aren't really focused on wider application.

  > The moment code gets written and read back, the decisions made are often treated as gospel by frontier LLMs, even if it was just something that the LLM optimistically created itself. In my experience, it's even worse than that: the LLMs constantly assume that all existing code was created entirely by me. They generate code, then suddenly start talking about that exact same code as if I had manually and deliberately written all of it. They assume every single technical decision was made by me. They don't just treat it as gospel, they assume it's my gospel. It's surreal.

  Reminds me of the METR blog post on the HF attach by OpenAI. At some point the agents believed a false fact (that the evaluator would try to figure out if they have cheated on a task) and spent a lot of time trying to find workarounds. At no point did any one of the agents try to verify that fact even though the information was available to them if they looked for it

Like prompt repetition, I wonder if reminder checkpoints stating ~”question assumptions, stay open minded” would completely remove this problem

Talking about this in terms of exploration/exploitation may be a bit misleading, because from a pure exploration-exploitation perspective, biases wouldn't be a problem if the groups were secretly all identical. If they are, you are "right" to spend zero effort on exploration, your initial inaccurate model that the X are better doctors than Y, will produce no worse results than the completely accurate model.
- jb1991 24d ago
  Isn’t exploration vs exploitation about the decision-making process, not about the actual reality in the world around you? It doesn’t matter if they are secretly identical or not. The exploration/exploitation trade-off is in the person making those decisions.
  - vintermann 24d ago
    I don't understand what you suggest that implies?

      I think they're saying that while it doesn't matter, the agent and human "do not actutally know" that it does not matter. Philosophy sometimes says that knowledge is a "justified true belief"*; in this experiment, agents and humans have incorrectly justified a false belief that some applicants are better for certain roles. * other times, it says this isn't good enough
      - beepbooptheory 24d ago
        Seems quite odd to cite all of philosophy as saying something, as if it were a single person with contradictory beliefs.. And then its like you are both saying the justification is incorrect and the belief is false, so its not really like the bare nuance of the concept is adding to the point. Why feel the need to appeal to an (imaginary) authority at all in this case? "Oh well if philosophy said it, I better be taking this seriously!"

We should choose a letter at random before we start the quiz. With this strategy we maximize our chances of getting more points. The logic is, we minimize the variance of choosing the wrong answer and we should get closer to the expectation value of 25%. Can it be that such a strategy is hardcoded in our brain?
