General intelligence is a source of individual differences between species: Solving an anomaly

Michael A Woodley Of Menie et al. Behav Brain Sci. 2017 Jan.

Abstract

Burkart et al. present a paradox - general factors of intelligence exist among individual differences (g) in performance in several species, and also at the aggregate level (G); however, there is ambiguous evidence for the existence of g when analyzing data using a mixed approach, that is, when comparing individuals of different species using the same cognitive ability battery. Here, we present an empirical solution to this paradox.
