Nice cut and paste, means absolutely nothing without the complete background, how about taking a stab at book learnin'.......... Not that I think you're capable.......
The culture argument is really BS.
Examples include.
A.) The IQ of Black Jamaica, and the Black Congo are similar, what do they have in common "Culturally" exactly?
B.) The IQ of White America, and White Finland are similar, what do they have in common "Culturally" exactly?
C.) Culturally White America, and Black America would probably have more in common "Culturally" rather than White Finland. (But, not in IQ.)
D.) Culturally Black Jamaica, and White Britain probably have more in common with each other, rather than with White Hungary, or Black Mozambique, why is it in each case the IQ fits closest with the race, rather than the culture?
E.) Culturally Ashkenazi Jews in the U.S.A would be sort of in between White Christian Americans, and Israelis, but the IQ of Ashkenazi Jews in the U.S.A falls higher than both.
F.) Native Americans from Alaska have IQ's more similar to Native Americans in Peru, than White people in Argentina do to Peru, or White people in Alaska do to Native Americans in Alaska.
G.) In Brazil, like the U.S.A, the IQ hierarchy is #1 Asian, #2 Whites, #3 Browns (Mestizos) #4 Blacks (African descent) The problem here, is that in Brazil they all tend to have been there awhile, and are all thus "Culturally Brazilian" and same often holds true in the U.S.A too.
H.) In Brazil, like everywhere else be it the U.S.A, or the UK, or in Asia vs White countries, the IQ patterns of Asians vs Whites are different, with Asians doing better on Spatial Ability, and Whites doing better on Verbal ability.
Here's the thing most Asians, and Whites have been in Brazil for a long time.
Shall I keep going on, and on?
