I don’t think any of them were dumb, just focused on the things they saw members of their community do.
Are you seriously suggesting that black people are genetically less predispositioned to program? Explain the evolutionary advantage to that please because that sounds absolutely absurd.
So even if they are more likely to be diagnosed - and I presume you mean White 'Men' explicitly, as Women are even less likely to be - they're also more likely to not 'sell' themselves during applications in the expected corporate way, and therefore not get the high-paying jobs.
Diversity is not just Race or skin colour, but that's easier to see (and to consciously bias).
So if there's some genetic bias at play, as long as the social issues are right there staring us in the face, you're going to need to advance the science of genetics to get the answer. Without that it just comes off "race science" and that kind of thing.
