You have made the important point here. There are certainly enough highly intelligent blacks and stupid whites that intelligence is a matter that has to be assessed on an individual and not a racial basis.
That said, I don’t know what the science may prove, but it seems to me that in the absence of evidence on either side, we should wait for the science to determine the answer.
Finally, why should science be concerned with social perceptions? If it turns out to be true that, as a race, blacks are less intelligent, as proven by valid scientific methods, should that science be censored?
