Well hate to rain on your parade but your 'science' is flawed in the sense that 'race' is a myth created a long time ago by people who felt thay had supreme 'intelligence' over others.

A recent review, by three Yale University scholars including

a former president of the American Psychological Association, firmly repudiates the view that IQ tests are a reliable “tape

measure” of human mental capacities, and they find that “attempts

to link intelligence, race, and genetics have lacked an adequate

scientific foundation” : “The statement that racial differences in IQ

or academic achievement are of genetic origin is, when all is said

and done, a leap of imagination. The literature on intelligence, race,

and genetics constitutes, in large part, leaps of imagination to

justify, post hoc, social stratifications”.

I have done my own work in this area and plenty of literature on the subject can be found publicly through most Anthropology Depts at major universites.

Have a look, it does open your eyes up.

Good luck!

I think there's one black guy who has a 190 IQ from Nigeria, but to my knowledge he's the only Sub-Saharan in History with an over 150 IQ.

By the way, how can you not be "Caucasian or of any ethnicity that has publicly in some facet or another declared itself 'supreme' even if by a minority of members"? All races have at least to some degree called themselves superior -- even the blacks.

It depends on where he received his education and the environment he was brought up in. In America you will find many black doctors, lawyers and scientists. In Africa people do not have such great opportunities to learn, or even be encouraged to learn. Life isn't "go and explore science" as it is in the States. So to say people who live in Africa score lower on IQ tests, okay I could believe that. But saying both a learned African and a learned "White Man" score radically different on an IQ test due to race is absurd, assuming both have had similar experiences and schooling. The brain is far more capable than any organ in the body. I don't believe it to have limits, but perhaps the disposition of people is the only thing to hinder it.

What do you mean by "native African?" You mean living in Africa? Nelson Mandella was obviously brilliant. Our American President is obviously brilliant. What are their IQs? Who knows? We don't generally know other peoples' IQs. If you are looking for African American high achievers, they should be easy enough to find on the web.
