The role of personality in individual differences in yearly earnings

We examined the role of personality in accounting for sex differences in yearly earnings among Australians (N = 533). Men reported they earned modestly more money than women did, as did married and fully employed people, but these three factors did not interact. Narcissism, psychopathy, extraversion, conscientiousness, and limited neuroticism predicted self-reported higher earnings; associations that differed little by participant's sex, although a slight pattern suggests women may pay a higher pay penalty for neuroticism but benefit more from conscientiousness than men do. Narcissism and neuroticism mediated sex differences in self-reported income suggesting men who were more narcissistic and women who were less neurotic reported more yearly earnings. The results are discussed in terms of how individual differences may play a role in apparent sex differences in earnings.
