Women's sexual competition and the Dark Triad

The Dark Triad (DT) of sub-clinical narcissism, Machiavellianism, and psychopathy has been found to be related to competitive attitudes and behaviors, chiefly in men. Using a women-only sample (n = 439), we examined the relationship of DT with general and sexual competitiveness. Factor analysis indicated that the distinction between inter- and intra-sexual competition in women may be less clear than previously conceptualized. We found significant positive correlations between DT and both general and sexual competitiveness. Regression analyses indicated that DT, and in particular, narcissism, are significant predictors of general and sexual competitiveness. These findings are discussed in relation to evolutionary theory, and directions for future work on sexual competition and DT are suggested.
