In other words- some groups of humans tend to have lower average IQ’s than other groups.
Filling colleges with larger numbers of dumb asses does not improve groups average IQ.
There are just more dumb asses with college degrees. The work done by said dumbasses is still work performed by dumbasses.
And people wonder why some groups of people have lower average pay and less wealth.
Maybe it’s all that diversity dumbing down the quality of college education for those not of the diverse group.
