I don't agree with your comment that it is genetics I think it is more environmental. If you take two smart people. Deprive one of them from sleep, water, food and then give them an IQ test in a dimly lit room that is freezing cold but don't do this to the other person on average the person who was not subject to all that crap will do better. This is the uneven playing field that AA was supposed to correct. If these racial based IQ test took into account the socio economic status of maybe 2 generations before the actual subject and normalized for that I wonder if the difference would be as big or even there at all.
