Familial Studies of Intelligence: A Review

Familial Studies of Intelligence: A Review

T J Bouchard Jr et al. Science.

Abstract

A summary of 111 studies identified in a survey of the world literature on familial resemblances in measured intelligence reveals a profile of average correlations consistent with a polygenic mode of inheritance. There is, however, a marked degree of heterogeneity of the correlations within familial groupings, which is not moderated by sex of familial pairing or by type of intelligence test used.
