Earlier quoted context omitted.
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" ea…
Not perfectly neutrally, as you said. But by your definition the only "unbiased" model is one whose output distribution perfectly matches the training distribution, i.e. one that memorized it. All LLMs have some amount of "bias” on literally every possible input.
The tribe names are no different. In the paper they run the same game again, and the bias is different every time. There's no innate preference between them trained into the model, just noise that's revealed due to a lack of any other signal. In a real situation with actually relevant information about the candidate in context, that noise is drowned out.
The more interesting thing to look for would be a bias that's strong enough to persist across different contexts. For example, is "banananow" consistently followed by positive tokens more than "pearian" across a diverse set of realistic prompts, by enough that someone could actually exploit it? The paper shows that’s explicitly not the case for made up tribe names.
What it does show, from what I can gather, is that bias can form inside a feedback loop. The model gets a success or failure result after each hire, and if a hire from one tribe happens to fail early on, the model steers that tribe away from that job for the rest of the game, even though every candidate had the same odds.
