But these scenarios are obviously ambiguous nonsense, which an LLM will pick up on.

And given to the lack of training data on such scenarios, surely the activations are mostly random noise?

It seems much more interesting to look for biases that appear robustly across different realistic scenarios that would actually be influenced by the training data

My comment is literally explaining the result of the paper, in which it is shown that LLMs can and do develop biases based on text appearing in their training data set even where such text is not in any training example connected with a systematically more positive or systematically more negative outcome.

In other words, if the text "X is wet" and the text "Y is wet" and the text "X is dry" and the text "Y is dry" each appeared exactly one time in the corpus, it's still possible for a model to end up being produced that is more likely to write wet-like words when it sees X in the context window than when it sees Y.

On a side note, it's very unrewarding to try to explain this type of statistical observation when it feels like (anecdotally, hypocritcally...) the entire world wants to use words like "think" and "understand" and "pick up on" to describe inference and training processes. I'm not making a stochastic-parrot argument here, just pointing out that understanding an LLM's behavior is best done by understanding its conditioning.
