Let's say I have two candidates, one is asian and the other is black, and on paper they both look great. They both attended Harvard, and they both interviewed well.
Now if I know that the average SAT score required for Asians to be admitted to Harvard is 1580, and the average SAT score required for Blacks to be admitted to Harvard is 1360, and all other metrics (GPA, conscientiousness, work habits, etc) fall along similar lines of differing standards, then I would have a statistical bias toward selecting the Asian candidate. Not because I'm racist, but because DEI and other equity efforts at Harvard have pre-biased the candidate pool for me.
In the absence of equity efforts, "I went to Harvard" would be a metric that stands on its own, independent of race. But with DEI, it is not. We have eliminated the "I hate them damn blacks" style of racism and replaced it with a more insidious "In order to make a statistically correct decision, I need to be biased against Blacks" style of racism. I'm not sure this is an improvement.
This is an example from college admissions, but the same analogy can be drawn in any environment with strong DEI influence.
I have a black friend who recently got a new boss, was forced to do months of intensive training training to "keep up". He ultimately ended up leaving the company despite being one of their most productive engineers.
It this sort of regressive opinion that keeps perpetuating the stereo type and forcing people out of jobs. Judge people based on what they are doing not what color their skin is.
