Does Anyone Know How To Read Anymore?

The reaction to a study written about in the New York Times, about racial bias by NBA officials has puzzled me.
Supposedly intelligent people like Michael and SCZA and an idiot like Charles Barkley all said the same thing, "of course there are more fouls called on black players, most of the NBA players are black."
That's the stupidest thing I've ever heard because that's not what the study says. The study says fouls are called on black players at a higher rate than white players by white referees.
At a higher rate. Not in total, but at a higher rate.
In fact, the study adjusted for factors like the players’ positions, playing time and All-Star status; each group’s time on the court (black players played 83 percent of minutes, while 68 percent of officials were white); calls at home games and on the road; and other relevant data.

Now that we understand what the study is saying (I hope), let's explain logically why it is nonsense.

1) The study states that white referees call 4.1% more fouls against black players than white. 4.1% is not negligible, but I don't view it to be enormously significant. It's within an expected range of variation.
2) They didn't study individual officials, only crews as a whole which often have a mixed racial makeup. So no consideration was taken about which ref actually made the call.
3) There's no way to determine which calls were correct and which were incorrect and which were questionable. And if you want to prove bias I think you have to show that black players were unjustly called for fouls white players wouldn't have been.
4) In correct for playing time and other factors, some of those (such as a player's all-star status, and even his position) are subjective factors.
5) As SCZA, correctly points out, most of the European players (minus Tony Parker and Boris Diaw) are white, and they tend to play less aggressively and therefore may realistically be expected to commit fewer fouls. Also, and I'm not sure about this but I think white players are more likely to play less foul prone positions (point guard) than black players (most of the centers are black).
6) What did they do about Yao Ming? And Jason Kidd? Did half his fouls count against each race?

In summary this study is stupid and pointless but not as stupid as people who say of course more fouls are called on black players, there are more black players in the NBA.
