Abstract. Mating Intelligence (MI) is a hypothesized constellation of mental adaptations that generate adaptive strategies in human mating (Geher & Miller, 2008). Although past research has theoretically explored and empirically evaluated the construct, using a MI scale that was borne of the ideas from Geher and Miller’s work, this study seeks further understanding of this construct by demonstrating incremental validity. Two studies, each with large samples, demonstrate that MI predicts important outcomes beyond traditional conceptions of personality and intelligence. Exploratory factor analyses revealed that the factor structure suggested in previous work was generally congruent with predictions. Further, MI accounted for a significant portion of variance in mating success after controlling for age, the five-factor model of personality and general intelligence.
