Joan Raymond for Newsweek:
Are men smarter than women? No. But they sure think they are. An analysis of some 30 studies by British researcher Adrian Furnham, a professor of psychology at University College London, shows that men and women are fairly equal overall in terms of IQ. But women, it seems, underestimate their own candlepower (and that of women in general), while men overestimate theirs.
Of course I myself am far too smart to fall into any such patterns of misestimation.
