Not exactly certain what you’re driving at. We know that different races have physical differences, because we can see them. We know that different races have genetic differences, because we can examine them. And we know that different races perform differently at different tasks, for example, the extreme dominance of West African descended runners in sprinting events. It seems that you are proposing that although there are known physical and genetic differences among races, to propose that psychological or intellectual differences could exist constitutes racism?
Another way to abstract it is to avoid IQ testing as a measure of intelligence, and to instead examine races under the lens of the theory of multiple intelligences: http://en.wikipedia.org/wiki/Theory_of_multiple_intelligences . Under such a model, is it fair to propose the possibility that different races might be skilled in different intellectual areas?
