Some authors defending the “hereditarian” hypothesis with respect to differences in average IQ scores between populations have argued that the sorts of environmental variation hypothesized by some researchers rejecting the hereditarian position should leave discoverable statistical traces, namely changes in the overall variance of scores or in variance–covariance matrices relating scores to other variables. In this paper, I argue that the claims regarding the discoverability of such statistical… Expand

The Elusive X-Factor: A Critique of J. M. Kaplan's Model of Race and IQ
Jonathan Michael Kaplan recently published a challenge to the hereditarian account of the IQ gap between whites and blacks in the United States (Kaplan, 2014). He argues that racism and "racializedExpand

Detrimental effects of an economic crisis on student cognitive achievement – A natural experiment from Palestine
Abstract In this study, we investigated the differential effect of regional economic prosperity on mean student cognitive achievement by analysing data from a “natural experiment” in Palestine. ItsExpand
The Evolutionary Gene and the Extended Evolutionary Synthesis1
It is argued that the evolutionary gene, when being materialized, need not be restricted to nucleic acids but can encompass other heritable units such as epialleles and current evolutionary theory does not require a major conceptual change in order to incorporate the mechanisms of epigenetic inheritance.

HEREDITY, ENVIRONMENT, AND RACE DIFFERENCES IN IQ A Commentary on Rushton and Jensen (2005)
J. P. Rushton and A. R. Jensen (2005) ignore or misinterpret most of the evidence of greatest relevance to the question of heritability of the Black–White IQ gap. A dispassionate reading of theExpand
