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
Openness to experience
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.
