Race, ethnicity, sex, and social potency

A social potency score was calculated for MIDUS Study participants (all Americans) based on the following items: is forceful and decisive; is persuasive and likes to influence others; enjoys leadership roles; enjoys being noticed, being the center of attention. Here are the means by race/ethnicity and sex (N = 3,735):

 
 
 
 
 
 
 
 
 
 
 
 
 
 
*significantly higher than men of English ancestry
**significantly higher than women of English ancestry
 
The mean for Jewish men is sixth-tenths of a standard deviation (sd) higher than the mean for English men--a fairly large difference.  The Jewish-English gap for women is smaller--a third of an sd.
 
The gender gap is largest for Mexican Americans, and smallest for Norwegian Americans.
 
The total male-female gap is about one-third of standard deviation.  According to this study, the heritability for social potency is 55%.   
 
In the new movie, little Alice slays the Jabberwocky (instead of a boy as in the original poem) and then steps into her father's shoes as an international business visionary. The story line is precisely where it belongs: in a fantasy.
