Anyone who thinks blacks are as intelligent as whites and asians needs to explain why
1. Black-americans come in last in all standardized tests. Asian-americans do fine on all the tests so it's not due to cultural bias in the tests.
2. Africa is by far the poorest and most backward continent on the planet. All of black africa is now controlled by blacks and has been for decades so it's not due to racism.
3. No black has ever won a Science Nobel Prize unless you count one in 1979 for the semi-science of economics. They have won many nobels in non-brain fields like Peace and also in Literature so it is not due to racism.
4. Out of 1552 chess grandmasters in the world, only THREE are black.
Now does that mean cause the over whelming majority of hockey players are Canadians anyone who is not Canadian can't play hockey? Or since the majority of winners of Nobel prizes for physics haven't been American, Americans are innately dumb when it comes to physics? Etc., etc., etc
Your conclusions are simplistic, and formulated without recognition of historical, cultural, or social factors
