When you talk about school performance, I believe that has nothing to do with race or ethnicity, and everything to do with upbringing and culture. Certain cultures like most Asians and Jews are brought up to put a very high value on learning and education. We have all heard about the Asian kids whose parents made them study for three hours every day after school.
When you talk about physical performance and especially the appearance of a physique, that's when we see real differences among racial and ethnic groups. Black males, on average, tend to be leaner and more muscular. Their calves are higher. Asians usually are shorter and lighter than other races, but have good calves. Why? Who knows. But it's true.
Funny Blockhead, I was driving somewhere last summer and passed a corner where three older black men were standing and drinking - not sure what, it was in the morning so hopefully not 40's. One guy looked to be at least 50 years old, had his shirt off, and could have stepped on stage and won almost any regional-level masters bb contest. Perfect six-pack, veins, intercostals. Maybe he actually was a bb, trained, did tons of cardio, and ate clean - but somehow I doubt it.
