The role of gender, task success probability estimation and scores as predictors of the domain-masculine intelligence type (DMIQ)

Sex Difference in Estimated Intelligence and Estimated Emotional Intelligence and IQ Scores

In five different online studies of community samples, participants (N > 2,200) estimated their IQ and EQ on a single scale and completed three different, short, untimed intelligence tests. In all studies, women estimated their IQ significantly lower than men (effect sizes from 0.22-0.47) and estimated their EQ higher (effect size 0.04-0.32). In only one study were there actual sex differences in IQ test scores. All correlations between the two estimates were significant and positive, and ranged from .37 < r < .47. The robustness of the IQ-EQ hubris-humility effect across measures and populations is discussed. Limitations are acknowledged, particularly in the use of tests.

Correlates of Self-Estimated Intelligence

This paper reports two studies examining correlates of self-estimated intelligence (SEI). In the first, 517 participants completed a measure of SEI as well as self-estimated emotional intelligence (SEEQ), physical attractiveness, health, and other ratings. Males rated their IQ higher (74.12 vs. 71.55) but EQ lower (68.22 vs. 71.81) than females but there were no differences in their ratings of physical health in Study 1. Correlations showed for all participants that the higher they rated their IQ, the higher their ratings of EQ, attractiveness, and health. A regression of self-estimated intelligence onto three demographic, three self-ratings and three beliefs factors accounted for 30% of the variance. Religious, educated males who did not believe in alternative medicine gave higher SEI scores. The second study partly replicated the first, with an N = 475. Again, males rated their IQ higher (106.88 vs. 100.71) than females, but no difference was found for EQ (103.16 vs. 103.74). Males rated both their attractiveness (54.79 vs. 49.81) and health (61.24 vs. 55.49) higher than females. An objective test-based cognitive ability and SEI were correlated r = 0.30. Correlations showed, as in Study 1, positive relationships between all self-ratings. A regression showed the strongest correlates of SEI were IQ, sex and positive self-ratings. Implications and limitations are noted.
