1) Black people are not actually less “good at stuff”, we just have a habit of defining “stuff” in a way that excludes the things that black people are more likely to excel at.
And, 2) Where black people do statistically worse, it’s not due to any innate difference, it’s because socially accepted “normal” support systems are more useful for people with challenges more common in white populations than challenges common in black populations.
So the idea is, if you change the support systems and measures of success to be more universal, the differences will go away.
And then the metric for whether administrative bodies have succeeded in this is “equal outcomes”. What you call “racism”.
But the inferences on which this affirmative action position are based make rational sense. There’s no logical flaw. There’s no conclusive evidence for these hypothesis either, but they are logically plausible.
The opposite perspective is the same: rational, yet lacking any basis in evidence. That is the perspective that black people, through biology, socialization, and/or culture, are actually “worse at stuff”. And the support systems and performance metrics are fair.
There’s no way to prove something is “fair” or “not fair” in the face of “unequal outcomes”. It just comes down to what you want to believe. There’s no rational basis to come to one conclusion or the other.
I choose to believe that all of the big categories of people are pretty similarly “good at things” but I can acknowledge that belief is a leap of faith. The truth is unknowable.
