“…For now, it suffices to say that some critics claim that data recollection for the article was not accurate, and that the authors may have rushed to conclusions, not considering other environmental variables [11]. However, this criticism has been sufficiently rebutted with more robust data, provided by other studies that confirm Rushton and Jensen's original arguments [12]. Furthermore, it should be noted that other studies have also added significant weight to the argument that the selective pressures of particular historical developments have also contributed to changes in IQ differences amongst populations.…”

Rushton and Jensen’s Work has Parallels with Some Concepts of Race Awareness in Ancient Greece

Rushton and Jensen’s “Thirty Years of Research on Race Differences in Cognitive Ability” documents IQ differences in populations on the basis of race. The authors explain these data by arguing that cold winter conditions in Europe had greater pressure for the selection of higher intelligence. Critics of Rushton and Jensen, and of the very category of race, claim that race is a social construct that only came up in the 16th century, as a result of overseas voyages and the Atlantic slave trade. The goal of this article is to refute that particular claim, by documenting how, long before the 16th century, in classical antiquity race was already a meaningful concept, and how some Greek authors even developed ideas that bear some resemblance to Rushton and Jensen’s theory. The article documents how ancient Egyptians already had keen awareness of race differences amongst various populations. Likewise, the article documents passages from the Hippocratic and Aristotelian corpus, which attests that already in antiquity, there was a conception that climatic differences had an influence on intelligence, and that these differences eventually become enshrined in fixed biological traits.

Hereditarianism is a school of thought that contends there are substantial evolved cognitive and behavioral differences among groups of humans which are both resistant to environmental intervention and are a root cause of differential social outcomes across groups. The relationship of betweengroup heritabilityto within-group heritabilityis one of the key theoretical components of hereditarianism and forms one of the bases for its claim to be an evolutionary science. Here, we examine the relationship betweenandand its application to problems in the hereditarian literature from an evolutionary genetic perspective. We demonstrate that the formulation of the relationship betweenandused in the hereditarian literature has no evolutionary content. By re-writing the relationship betweenandin a novel evolutionary framework, we demonstrate that there is no way to predictusingwithout considerable additional theory that is absent from the hereditarian literature. Furthermore, we demonstrate that the hereditarian technique that usesandas a means of judging whether a given difference between groups may be plausibly ameliorated through environmental intervention is mathematically flawed. Lastly, we fill a gap in the hereditarian literature by writing out a means of usingto predict the absolute difference between groups under a neutral evolutionary model and find that it is much smaller than claimed by hereditarians. In conclusion, we propose a path forward for the study of human variation that moves us past the ill-conceived nature vs. nurture question and allows us to focus on more productive issues.

“…We have re-evaluated the paper with the assistance of scholars in the field, the editor who accepted the paper for publication, and the author. Given that the author has a high profile in the field, we believe that [1] has value in providing an insight into the author's own opinion of his research and the field as a whole. However, we recommend against using it as established fact, and that statements made in the article should be treated with skepticism.…”
