How is race or sex aware hiring going to help with eliminating subconscious bias? 
It reinforces bigotry, because it gives a rationalization for bigots to not respect their minority coworkers, as they can claim that they were not subject to the same scrutiny when they were hired.<p>What is the historical justification for the effectiveness affirmative action? Certainly, countries like Malaysia and South Africa with extreme disparity seem to have mixed results at best.<p>I agree that pretending ethnicity&#x2F;sex are not visible, is not the same thing as making ethnicity&#x2F;sex invisible. 
But actually implementing enrollment and employment laws or policies that hide this information from decision makers could make it <i>nearly</i> invisible.<p>That&#x27;s actually not the fundamental problem though. Even if you managed to a perfectly even proportion of middle class stem graduates from 1st and 2nd tier universities represented on your payroll, you&#x27;ll still end up with a monoculture. Not because of some hard to pin down unconscious bigotry, but because little has been done to eliminate class from society, and social class is a big factor in a persons access to education and the quality of their childhood.<p>Poor, working class women have less work opportunities than men, as less educated ( religious ) working class people tend conform to traditional gender roles more than middle class people, well paid working class jobs require more physical strength, and unlike middle class mothers, working class mothers cannot afford childcare or help with housework while working or studying.
Like ethnicity, class is almost hereditary so is easily confused with ethnicity in statistics.<p>Making the statistics look better by hiring proportionally more middle class minorities is a face saving exercise, not a solution.
