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.
