In terms of group differences, people of northeast Asian descent have higher average IQ scores than people of European lineage, who in turn have higher average scores than people of sub-Saharan African descent

The average score for Hispanic Americans falls somewhere between the white and black American averages. The American Psychological Association (APA) issued a report in 1996 and concluded that IQ tests reliably measure a real human trait, that ethnic differences in average IQ exist, that good tests of IQ are not culturally biased against minority groups, and that IQ is a product of both genetic inheritance and early childhood environment.
