Abstract

This commentary integrates the contents of four recent articles on individual differences (Nye, Su, Rounds, & Drasgow, 2012; Schmidt, 2011; Valla & Ceci, 2011; von Stumm, Hell, & Chamorro-Premuzic, 2011) in a causal theoretical model. In this model, introversion and fluid intelligence cause interest in general learning (intellectual curiosity), which in turn is a major cause of crystallized intelligence. Certain specific interests and fluid intelligence also contribute to crystallized intelligence. Prenatal testosterone hormone conditioning is postulated to cause sex differences in certain specific interests but not in others. Crystallized intelligence, specific interests, and the personality trait of conscientiousness cause adult academic and occupational performance, whereas crystallized intelligence is the main cause of good mental functioning at older ages. Research is presented supporting each link in the model.
