Scientists disagree with idea that there is a connection between race and intelligence, and they don't support IQ tests as even being valid in the first place.    "The idea that intelligence can be measured by IQ tests alone is a fallacy according to the largest single study into human cognition which found that it comprises of at least three distinct mental traits. The results question the validity of controversial studies of intelligence based on IQ tests which have drawn links between intellectual ability race, gender and social class and led to highly contentious claims that some groups of people are inherently less intelligent that other groups.  The results disprove once and for all the idea that a single measure of intelligence, such as IQ, is enough to capture all of the differences in cognitive ability that we see between people.  ...from a scientific point of view, the notion of race is meaningless. Genetic differences do not map on to traditional measurements of skin colour, hair type, body proportions and skull measurements. Now we have shown that IQ is meaningless too Dr Highfield said."  https://www.independent.co.uk/news/science/iq-tests-are-fundamentally-flawed-and-using-them-alone-to-measure-intelligence-is-a-fallacy-study-8425911.html
