Table 3.

Moderated polynomial regressions on the educational attainment 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 11^th year case weight assigned by the Project Talent staff to account for attrition. Bold font indicates p < .001 (alpha level was set based on a Bonferroni correction to account for the number of analyses conducted across this data set).
