Intrinsically. Someone with an IQ of 85 will not be successful in college.
The idea that anyone can be anything is harmful to everyone. If you are 5’2”, you won’t make it in today’s NBA. If you are 400lbs, you are not healthy.
I’m sure some people have been failed by the K-12 educational system, but the answer isn’t to further degrade the college system.
This assumes "IQ" is fixed, but it isn't.
