Why do you think these numbers are fixed? They can change, if there exists competency and a desire to learn. You are also ignoring the effects of changing environment which those numbers disregard. For example, we know blacks disproportionately come from low income backgrounds with higher crime and a "rough" home life, which can affect a childs ability to effectively study and learn. That's not because they're genetically black as you allude, that's because they grew up in that environment. Your data does not capture or ignores this crucial variable and you should stop pushing it.
