That’s what we’re trying to fix (or at least mitigate) in the US. You say it is just human nature, but we’re a pretty diverse country, so we have a strong incentive to proactively try and see if we can make it work.
To me that's exactly what helps lead to discrimination versus not knowing ethnicities and treating employees as anonymized numbers which would be fair to everyone.
Currently in the US, businesses don’t actively have official policies of bigotry. If they did, collecting that data could be harmful. But instead we have bigotry as a sort of soft social thing, a compounding of many little challenges, “bad culture fit,” that sort of thing. Because it is subtle, we need to keep it from slipping under the radar.
