We'll be hearing a lot more about comments by basketball legend Larry Bird here. The two choicest were where he said of basketball "it's a black man's game", and how it bugged him when the other team would have a white guy guard him.
Mr. Bird is no scientist, but he certainly has been in position to make subconscious firsthand empirical observations. The utter dominance of black players in the NBA is hard to miss.
Has there ever been any scientific basis at all for this silly idea that intellectual and physical gifts and tastes are evenly distributed by race and sex? Whether these result from geography, culture or genetics is beside the point - the result is still there.
