Jews and Big 5 traits

I estimated OLS models for Big Five personality traits with self-esteem and whether or not you are Jewish as predictors (sample size = 3,915--94 Jews):

Standardized OLS regression coefficients

Extraversion
Jewish .03*
Self-esteem .40*

Negative emotionality
Jewish .04*
Self-esteem -.51*

Agreeableness
Jewish .02
Self-esteem .17*

Conscientiousness
Jewish .01
Self-esteem .37*

Openness to experience
Jewish .03*
Self-esteem .39*

Controlling for self-esteem, Jews are significantly more extraverted, negatively emotional, and open to experience. They are not more conscientious or disagreeable (as I thought they would be).

By the way, Jews do not differ from others in self-esteem.
