Humans have a much greater diversity in bias because we have all lived our own unique lives. LLMs are incredibly limited, by contrast. Even if you were somehow to simulate bias by exposing subsets of LLMs to subsets of human knowledge corpuses, you would need billions of subsets to simulate the diversity of human bias.

Wisdom of the crowd also implies that diversity of human bias is a good thing, in aggregate.

To more closely address your point: if all companies use the same LLM they’ll all have the same hiring bias. But if Company Foo has Hiring Manager Bob that’s biased against me, I can shoot my shot with Company Bar with Hiring Manager Alice who might not be.
