They're trained on human data. I would expect them to emulate human biases as closely as possible.
Your comment stopped me in my tracks a little bit.
Is a 'bias' in a piece of writing generally a property of word to word choice and sentence to sentence construction or is it something more nebulous? Especially in terms of the appreciation of mathematics and someone's hesitance about publishing a mathematical argument they think is ugly or brute forced in some way.
Is it? I'd expect most of the training set to be synthetic data extrapolated from a small set of human authored texts.
It's more complex than that, especially as post training is often goal based.
No, they are not. Specifically, this was a method based specifically on learning from scratch, like most modern AI models.
Why do you think it's called Alpha ZERO?
This is where harness, and the fact that a machine can be endlessly prompted to try again comes in.
Even if an LLM starts by pursuing things that follow human bias, continuous failures and re-prompting to try something different will eventually force it to consider things outside of what ever biases it has.
You can do the same thing to a human. But most people would consider it unethical to lock someone in a box and force them to keep trying to solve the same problem over and over again until they figure it out.
