Discrimination in employment against blacks and other minorities operates on job applications sight-unseen: employers reject them because the applicant's name sounds like a black.

This article reports on the UK situation, but I expect it is the same in the US.

I wonder if it is possible to do something about this by preventing the application from showing the applicant's race. But would that make a real difference in who gets hired, or would it only postpone application of the bias?

There is evidence of applying bias against women in a similar way.
