I don't agree with you about the IQ, its simply not true and some say it based on several seriously flawed studies.
Will you answer my question...
Do you believe that, with regards to IQ, the white race is superior to the black race?
I don't think its nec a brain superiority thing. I think it is culture and attitudes to learning.
Whites and Asians have deep cultural traditions that value honor, learning, and discipline. Think back to knighthood and samurai philosophies. Which is why these ethnicities tend to succeed in the modern world.
This culture does not exist in Africa, SA, nor ME. Without a strong culture that values education, honor, discipline, etc. you won't succeed.
