Group differences in IQ are best understood as environmental in origin

Abstract

Responds to the comments by J. P. Rushton (see record 2012-24333-012); M. A. Woodley and G. Meisenberg (see record 2012-24333-013); and J. D. Mayer, D. R. Caruso, A. T. Panter, and P. Salovey (see record 2012-24333-014) on the present authors' original article, "Intelligence: New findings and theoretical developments" (see record 2011-30298-001). Here, the authors address the concerns raised by Rushton and by Woodley and Meisenberg, and conclude by agreeing with Mayer et al's claim that many types of abilities can be thought of as intelligence of a kind. They note, however, that it has proved hard to show that measures of emotional intelligence or social intelligence contribute to behavior we would want to call intelligent over and above their correlation with conventional IQ tests.
