A reader raised the question about racial differences in honest self-reporting. I ran across this study of 980 children with a mean age of eight. It found that black children score the highest on the "lie scale" (with questions like, "I never get angry"--obviously dishonest if you answer yes), while Hispanic children scored the highest on concerns about living up to others' expectations (the "social concerns scale"). Whites scored lowest on the lie scale. The black-white gap is 37 percent of one standard deviation--a moderate difference.
