153 sociology students specified parental occupation and job status before estimating their own and their parents' overall IQ. Male subjects, as predicted, gave a higher mean self-estimated score to themselves than did female subjects (113 vs 106). Fathers were awarded higher IQ scores than mothers (114 vs 107). Male subjects who had mothers in a higher social class gave themselves the highest mean score.
