The study:

The stated purpose:
we investigated whether individuals with IQs ≤ 90 who completed college experienced the same social and economic benefits higher-IQ college graduates did.
The hilarious accidental money shot:
Although most individuals with IQs ≤ 90 did not have a college degree, the rate at which they completed college had increased approximately 6-fold in men and 10-fold in women relative to rates in the previous generation.
So the researchers were trying to instill confidence in their sample size, but they inadvertent revealed what most of us have suspected for years: colleges are rubber stamping degrees for stupid people in general and stupid women in particular.
Given average white IQ is ten points higher than 90 while average black IQ is five points lower, it’s probably safe to assume that most of these cognitively challenged college grads are black women a.k.a. the most insufferable and belligerent demographic on the planet.
We’re fast tracking literal retards into positions of authority and influence because muh racism. Bodes well!
You can hire based on whatever you want, but if you get even a bit successful you'll get sued, because lack of equity is proof of discrimination.
"But your honor, I followed a blind process, and hired just based on basic competence and not being a retard" isn't going to help you.
