MIDUS study participants were asked: "I enjoy being unique and different from others in many respects." In personality research, this item is a measure of narcissism. Here are the means by race/ethnicity (N = 3,980):
Narcissism mean score
*significantly higher than whites at the 95% confidence level
The black mean is 1/2 a standard deviation higher than the white mean--a moderate difference. The higher measured black level of self-esteem might be actually tapping greater narcissism.
Gay men 4.79*
Bisexual men 4.59
Straight men 4.13
*significantly higher than straight men at the 95% confidence level
The mean for gay men is more than four-tenths of a standard deviation higher than the straight male mean--also a moderate difference.
