It's very sad that "free from sexist, racist, ageist biases" is considered "worse", surely?

Do you agree?

Yes, I agree (check my comment history over the last few days to see which side I fall on).

I meant worse for the problem the GP was trying to solve.

The method (free from sexist…) is better but the outcome (employee similarity to general population) is worse.

I guess it really comes down to the ethical framework you accept as valid, deontological or utilitarian...
