Quote:
The American Psychological Association published a study in 2005 showing that IQ differences along racial lines are more genetic than the result of environment... A 60-page review of the scientific evidence, some based on state-of-the-art magnetic resonance imaging (MRI) of brain size, has concluded that race differences in average IQ are largely genetic.
"Neither the existence nor the size of race differences in IQ are a matter of dispute, only their cause," write the authors. The Black-White difference has been found consistently from the time of the massive World War I Army testing of 90 years ago to a massive study of over 6 million corporate, military, and higher-education test-takers in 2001.

IQ and Wealth of Nations by
Dr. Richard Lynn and
Dr. Tatu Vanhanen, father of the Finnish Prime Minister, studies the average IQ of 81 countries around the world. The top 10 countries with the highest average IQs are all in the Pacific Rim and Europe. The bottom 10 are all located in Sub-Saharan Africa. In countries like Jamaica, where the population is of Sub-Saharan decent with little to no Caucasian admixture, the average IQ is similar to that of the Sub-Sahara.

The “coloreds” constitute about 10% of the population of South Africa. Their average IQ mimics American blacks (who also have a large Caucasian admixture) and not other Sub-Saharan Africans.
