Moderated polynomial regressions on the annual income outcome (one independent regression for each of the Big Five). Model 1 controls for gender, race, and age. Model 2 adds controls for IQ, IQ-square, and IQ X SES.

Notes: Unstandardized regression coefficients. Gender and race are effects coded (men = −1, women=1; non-whites=−1, whites=1). Personality traits, intelligence, parental SES, and age cohort were standardized prior to the analyses. All regression analyses were weighted by the 11th year case weight. Bold font indicates p < .001.
