I doubt it, because the groupings you mentioned are themselves arbitrary. We could just as easily split society into tall people and short people. The distribution of professional basketball players is always going to have more of the tall group than the short group, simply because the rim is arbitrarily at 10 ft. If a particular ethnic group happens to be taller on average than another, it's likely they will be more…
> What we want is not proportionate representation based on arbitrary groups, but rather the correct representation. We want the best basketball players to be playing basketball, because that makes it more fun for the rest of us to watch. Let me reiterate what I infer from your words: 'black people are naturally more athletic, so they should keep playing basketball, and leave all that pesky business and government-ru…
I was literally thinking about the Dinka tribe from Sudan (who are very tall on average) and the Pygmy tribes of the congo (who are very short on average). Google them for data.
Alternatively, you can look at the well-studied difference in height between men and women. Do you deny this exists?
I could have just as well used tennis, where the vast majority of top players are white or soccer (where there's a quite proportionate distribution within the countries that play). In tennis, the ideal height is between 5'10 and 6'2. If you are much shorter, you have a disadvantage in serving. If you're much taller you have a disadvantage getting to low balls.
What I meant is that it's highly unlikely that the particular set of characteristics that determine success in any endeavor will be spread evenly amongst arbitrary groups. It doesn't matter what those groups are. We want the best set of individuals for the job, whatever it is.
