most likely he was wrong on IQ of blacks.

but controversial studies should be allowed, as long as it is done following scientific ways. it's OK public funding not given, but private ones should be ok.

it's fine to criticize scientists or sponsors involved, but hopefully all within scientific channels.

even if controversial findings are credible , doesn't mean racial or political incorrect views are right.

say even if blacks are found IQ lower, instead of justifying the discriminations, people need to ask why is that, any remedies either to increase the IQ or compensate in their lives.

a few subjects i cna think of worth keep studying:

how much homo sexuality determined by genetics and social interactions?

how much transgender(laymen words men into women) have physical advantage (comparable to PED) over traditional women? noted all those difinations are not scientific,a nd it's complex.

just forbid those studies are only going to backfire. openness is always better.
