Richard Posner is a US federal appeal court judge. He talks openly about races and IQ differences at his blog.
Becker Posner and Sailer also even talk about Jewish IQ differences.

Finally, I am not clear what we should think the problem of American education (below the college level) is. Most children of middle-class (say upper quartile of households, income starting at $80,000) Americans are white or Asian and attend good public or private schools, usually predominantly white. The average white IQ is of course 100 and the Asian (like the Jewish) almost one standard deviation higher, that is, 115. The average black IQ is 85, a full standard deviation below the white average, and the average Hispanic IQ has been estimated recently at 89.
Black children in particular often come from disordered households, which has a negative effect on ability to learn and perhaps indeed on IQ (which is only partly hereditary) as well. Increasingly, black and Hispanic students find themselves in schools with few white or Asian students. The challenge to American education is to provide a useful education to the large number of Americans who are unlikely to benefit from a college education or from high school courses aimed at preparing students for college.
The need is for a different curriculum and for a greater investment in these children’s preschool environment. We should recognize that we have different populations with different schooling needs and that curricula and teaching methods should be revised accordingly. This recognition and response should precede tinkering with compensations systems.

The floodgates are open. How about Whites get their own separate schools that are normed to their IQ? I say the Constitution requires it to provide fair and equal education. This is based on over 50 years of experience. A reference Sailer has made as well in the past, although I am not sure the context.
