You can reject massive 35 year longitudinal studies if you wish. I am unaware of any data or studies that indicate Terman was wrong.
Proof by counterexample = black people
Average intelligence < white people
Average athleticism > white people
Not a counter example.
If the Terman data is sound and can be extrapolated to the population as a whole then black college graduates should be on average more athletic then blacks who did not go on to college.
The same should hold for white college graduates and for college graduates in general regardless of race.
