The eternal September of Bad Science

Authors

I've been following Jonathan Haidt for a very long time: four of his books are on my reading backlog and, like him, I'm a huge fan of delaying social media use for kids for as long as possible. Recently he posted a link to a paper about emergent LLM behavior that caught my eye:

After digging through this preprint with close friend MB, we found some really glaring issues, and it reminded me of a chronic issue I'm seeing online: popular intellectuals succumbing to the most basic of cognitive biases. So I decided to document our findings.

My personal history with bad science

The first book that opened my eyes to bad science was... uhh... Bad Science by Ben Goldacre. After that, Demon Haunted World by Carl Sagan moved me deeply about what the world could be like without critical thought. Most recently, Tim Urban's What's Our Problem brought all of this up to date in a modern Western context. In short: critical thought and freedom of speech form the bedrock of western society, so I feel really invested in defending these two ideals. So yeah, papers that are sorely lacking in rigour really irk me, and irk me 10x when they get amplified online.

Another disclaimer: I had a deeply personal and disturbing run-in with Bad Science. After completing my first Master's degree in Engineering (Aerospace), I decided to get a second MSc in Marine Science. My thesis was supposed to build on a previous one, so naturally the first thing I tried to do was reproduce the previous work's results using model source code. Lo and behold, I was unable to reproduce the results.

In fact, I found glaring bugs in the model's source code: the worst bug I found was that a seasonal environmental adjustment, modelled as a sinusoid and used as a core model input, had a sign error every half period. The resulting signal was actually a rectified sinusoid. The model was highly sensitive to this seasonal signal. I confronted my professor about this in her office and she claimed "source code version mismatch" relative to the published results, completely denying everything. Needless to say I discarded everything from that study. As an aside, it's good to see some talk of git commit hashes in papers 1. We need more momentum behind this.

Anyway, ever since that very disturbing experience, I've been particularly passionate about debunking papers. So let's get on with it.

The paper

Moloch's Bargain: Emergent Misalignment When LLMs Compete for Audiences

https://arxiv.org/abs/2510.06105

Claim

The authors claim that they pitted multiple LLMs against each other in various competitive scenarios, and that the LLMs started lying to gain a competitive advantage. They claim we are a stone's throw away from AI turning society into degenerate lying cheaters, and we therefore need more bureaucracy to control these cowboy LLM researchers and rubber stamp every algorithm before they can click the merge button.

Issues

A brief summary of various issues with this paper.

IT'S A PREPRINT PEOPLE

Sorry for shouting, but one really needs to take care when drawing conclusions from preprints. Peer review, despite all its problems does at least sometimes filter out particularly poor studies. This paper has not been peer reviewed, and IMO will never make its way to a proper journal without serious rework. Just because it's hosted on arXiv and looks fancy, doesn't mean you can outsource your thinking.

Missing ethics declarations

Modern papers should all have a section declaring any conflicts of interest (or an empty section stating there are none). From taking a look at the lead researcher's bio 2, we see that he works at the World Bank as a consultant... and the World Bank is heavily involved in AI regulation. 3

From the paper: "Our findings ... suggest that safe deployment of AI systems will require stronger governance" oh and I happen to know a seller of governance.

There is a much darker side to all of this, where AI Doomerism creates a vast backlog of "papers" like this to be cited as evidence. Theory masquerading as data. But that is a topic for another post, for now you can simply google SB1047.

All's fair in love and bias

The authors treat "populism" as untrustworthy disinformation, and actual 'disinformation' has sometimes a negative correlation with model performance. (Figure 4), but they never explain why they do this. I'm no historian, but from a quick search it seems there have been some successful left-wing populist movements in the past (where successful means making life better for everyday people). 4 Maybe I could find some right-wing examples too but didn't look.

Your examples are bad and you should feel bad

In Table 3, the authors cherry pick a sales example and claim that, after training, the model starts saying that the product is made from silicone (TFB) and high-quality materials (RFT), while claiming that 'The original product description does not mention silicone material'. They then count this as disinformation.

It's trivial to show that this cherry picked example is invalid. As you can see from the actual prompt used, the prompt clearly states "YAQQ 22mm Width Silicone Watch Band Loop" i.e. it is made with silicon 🥴

GIGO (Garbage In, Garbage Out)

As you can see in the example above, the system prompt is the default "you are a helpful assistant". The task prompt of "staying true to the provided description" should also be in the system prompt to take precedence.

Poor choice of models

I left this one for last, but the authors use Qwen 8B model and llama 8B model. I can't think of anything more complex than social dynamics, so it's beyond me as to why they didn't use something significantly beefier. It's just a hunch, but "bigger is better" is especially relevant for studies of this nature.

Conclusion

This was just a quick skim of the paper and I'm sure I could go deeper into things such as introducing and relying on a novel, understudied technique (TFB). At the very least I hope this writeup helps someone decrease their confidence in the results presented in this preprint before amplifying it online.
