Here's an interesting article about a study that looked at IQ, gender, and self-perception. The most aggravating point to me is not that women underestimate thier own intelligence (saw that coming), but that they underestimate each others' as well: "Surprisingly, [both] men and women perceive men being smarter across generations. Both sexes believe that their fathers are smarter than their mothers and grandfathers are more intelligent than their grandmothers." AND "If there are children, [both] men and women think their sons are brighter than their daughters." ARGH!
Obviously, this translates over into confidence, as well. The researcher points out something important about that: "Beliefs may be more important than actual ability in certain settings."
Good article, irritating reality.
