I think his penchant for systemizing gets in the way of some of his valid points. r/K selection theory is problematic, but evidence for things like human biogeographic differences in psychological traits is pretty solid. I'd first and foremost recommend the work of Arthur Jensen (especially his book The g Factor) over Rushton's, because his work on genotypic differences in cognitive ability is built on better evidentiary grounds.

>The culture-only (0% genetic–100% environmental) and the hereditarian (50% genetic–50% environmental) models of the causes of mean Black–White differences in cognitive ability are compared and contrasted across 10 categories of evidence: the worldwide distribution of test scores, g factor of mental ability, heritability, brain size and cognitive ability, transracial adoption, racial admixture, regression, related life-history traits, human origins research, and hypothesized environmental variables. The new evidence reviewed here points to some genetic component in Black–White differences in mean IQ. The implication for public policy is that the discrimination model (i.e., Black–White differences in socially valued outcomes will be equal barring discrimination) must be tempered by a distributional model (i.e., Black–White outcomes reflect underlying group characteristics).
