Of course the British politically correct rant about CULTURE. How is it possible that negroids have the same culture whether they have lived for 400 years in the USA or forever in Cameroon? DIFFERENCES ARE GENETIC and cannot be erased. Referring to other studies on this site: negroids mature faster, have a different muscle structure so they jump higher, have higher muscle mass and thicker bones. At the same time, they have almost 20% smaller brains, a massive underdevelopment of the frontal lobe of the cerebral cortex which prevents them from thinking abstractly, predicting the future to a degree equal to whites. The average IQ of a negroid is 70%, and I remind you that all currently living negroes have already received our genes! Research shows that measuring self-awareness is inextricably linked to the context of our development. Self-awareness tests can be culturally biased, suggesting that the ability to pass a mirror test may be delayed in non-Western cultures. A study in Zambia found that children raised in an interdisciplinary culture performed better on self-awareness tests than children from Western cultures.
