An aggression score was calculated for MIDUS respondents based on the following items: is physically aggressive; enjoys upsetting and frightening others; enjoys scenes of violence; victimizes others for own advantage; will retaliate; is vindictive. Here are the means by race/ethnicity (Sample size = 3,392):
Mean aggression scores
Males (n = 1,783)
Females (n = 2,209)
* significantly higher than white counterpart
The high score for Asian males might be anomalous (there are only 7 respondents) but in an analysis of GSS data, I found that Chinese Americans were most likely to agree with a pro-violence statement. Black men are only two-tenths of a standard deviation above white men--a small difference. On the other hand, the mean for black women is more than four-tenths of a standard deviation above that of white women, a moderate difference. Notice how scores for Amerindian women are similar to their male counterparts, while Mexican American women are higher than the men.
