Bias causes US women and blacks to get worse medical care. For some kinds of problems, the crucial responsibility of bias has been scientifically proved by adopting systems that eliminated the possibility of bias.

The article linked to just above displays symbolic bigotry by capitalizing "black" but not "white". (To avoid endorsing bigotry, capitalize both words or neither one.) I object to bigotry, and normally I decline to link to articles which promote it. But I make exceptions for some articles which give important information about racism or the fight to eliminate racism. That article is one of the exceptions.
