There is no way to prove that correlation, B_L. Having worked in a predominantly black school, I would wager that poor academic performance is due more to a cultural shortcoming. Black kids who excel academically are ridiculed by their peers. Also, I had a 6th grader tell me once that he "didn't have to do his work because he will always receive a check." Obviously, the kid heard this at home. Neither of these problems are a circumstance of racism.
