Keep in mind the utter lie that is the gap/superiority of college degrees.
Do not forget that most recent non-STEM degrees are in the garbage areas of : gender studies, racism, etc. Basically, anything that criticizes the West and caucasians..
Ignore any such stats. It is conflation, at best.
I would much prefer the Intelligence of any electrician, plumber, or mechanic over that of someone whose degree is in anything ending in the word “studies”. Even when the modifier might lead to a worthwhile degree, such as biology, a check of the curriculum for “biological studies” shows it is much weaker. The DEI and grievance studies majors are worse than worthless.
