Hans Eysenck defended the hereditarian point of view and the use of intelligence tests in "Race, Intelligence and Education" (1971), a pamphlet presenting Jensenism to a popular audience, and "The Inequality of Man" (1973). He was severely critical of anti-hereditarians whose policies he blamed for many of the problems in society.
[1] [2] Intelligence in the normal range is a polygenic trait, meaning that it is influenced by more than one gene, [3] [4] and in the case of intelligence at least 500 genes. [5] Further, explaining the similarity in IQ of closely related persons requires careful study because environmental factors may be correlated with genetic factors.
Spearman's hypothesis is a conjecture that has played a historical role in debates surrounding race and intelligence.Its original formulation was that the magnitudes of black-white differences on tests of cognitive ability positively correlate with the tests' g-loading. [1]

It has been a focus for controversy in the debate over race and intelligence. The aim of the study was to determine the contribution of environmental and genetic factors to the average underperformance of black children on IQ tests as compared to white children. The initial study was published in 1976 [1] by Sandra Scarr and Richard A. Weinberg.
