Evolution, brain size, and variations in intelligence

Louis D Matzel et al. Behav Brain Sci. 2017 Jan.

Abstract

Across taxonomic subfamilies, variations in intelligence (G) are sometimes related to brain size. However, within species, brain size plays a smaller role in explaining variations in general intelligence (g), and the cause-and-effect relationship may be opposite to what appears intuitive. Instead, individual differences in intelligence may reflect variations in domain-general processes that are only superficially related to brain size.
