We know how to reduce bias in hiring. Using a blind audition. A much smaller amount of information about the applicants origin leaks through. Implicit bias is attacked via limiting the information that it can act on. It seems categorizing people by race and gender at the individual level is a recipe for disaster and gives racists the power to do exactly what they want, pick and choose which types of people get to benefit. If you give a regular person information about a persons race and gender, the damage they can do is limited to whatever implicit bias (if any) they have. If you give these tools to a racist or sexist, you've given them the keys to the kingdom. The conclusion is, why is Microsoft making it a requirement to know about race and gender at every single hiring step? Surely this just needs to be an aggeregate statistic right?
