Men are overrepresented at the tails of the IQ distribution, women are overrepresented in the middle.

Maybe most notable is a 1995 paper in Science http://www.sciencemag.org/content/269/5220/41 but it is both behind a paywall and completely devoid of figures! You get the main idea from the abstract, though: Except in tests of reading comprehension, perceptual speed, and associative memory, males typically outnumber females substantially among high-scoring individuals.
While there may be gender differences among high/low scoring individuals, I resent that that this is treated as a scientific fact when there are limited studies with contradictory findings.
