I'm sorry but I am having an absolute bastard of a time finding respectable scholarly journal articles that you don't have to pay for. I'm having flashbacks to writing my thesis. In any case here is an article that at least sort of explains what I mean when I say race is culturally constructed. When most people refer to race they are actually refering to dominant phenotypes it may seem like an arbitrary distinction but in terms biological classifications it is not. http://amst101.blogspot.com/2010/05/4-cultural-construction-of-race.html
And if you are really interested in my point of view you can buy this I guess: http://www.ncbi.nlm.nih.gov/pubmed/19226639 From the abstract: Phenotypic traits have been used for centuries for the purpose of racial classification. Developments in quantitative population genetics have allowed global comparison of patterns of phenotypic variation with patterns of variation in classical genetic markers and DNA markers. Human skin color shows a high degree of variation among geographic regions, typical of traits that show extensive natural selection. Even given this high level of geographic differentiation, skin color variation is clinal and is not well described by discrete racial categories. Craniometric traits show a level of among-region differentiation comparable to genetic markers, with high levels of variation within populations as well as a correlation between phenotypic and geographic distance. Craniometric variation is geographically structured, allowing high levels of classification accuracy when comparing crania from different parts of the world. Nonetheless, the boundaries in global variation are not abrupt and do not fit a strict view of the race concept; the number of races and the cutoffs used to define them are arbitrary. The race concept is at best a crude first-order approximation to the geographically structured phenotypic variation in the human species.
As for the variance in standardized test scores among different races in America again difficulties in finding scholarly journal articles that are both relevant AND free. It is late here(I'm currently in Indonesia) I'm going to bed but if there is still any real interest in this thread tomorrow I will get back to it tomorrow night after my journey to Singapore. Night
There is a numerical effect here. If, for the sake of argument, we consider a chess rating of 1500 average, 2000 and up is a good player, and 1000 and below is a poor player, if you have 5 chess players, you'll probably only find one in the above 2000 range. If you have 50 chess players, you'll probably find 10 who are above 2000. The odds are much greater that one of those ten will also be above 2200 in comparison to the one in the case where there were only 5 players total. If you take 500 chess players, you'll find 100 that are above 2000, and you'll definately find players over 2200, and the odds of finding players over 2400 increase. As you find more and more players, higher ratings become more accessible. In highschool, I was on the swim team, and whenever we would have a meet with the high school on the other side of town, they would always win. The racial make up was the exact same between the two teams, and the two schools were separated by a 5-10 minute drive (so there was no geographical difference). The difference was that their team was always at least 2-3 times larger than ours, and so they were more likely to have better swimmers.
I think that an individual can be inherently suited to a particular endeavor, but I don't think it's necessarily spread throughout an entire race. When there is a person of a particular race (whose race isn't commonly involved in that activity) who dominates the competition, sometimes that ignites interest in the community, and in effect this finds those who are inherently good (whereas without the well-known person, these people would have never been culturally pushed into trying the activity, and their ability would have never been discovered) and then we start to see that race dominating.
