ScienceDaily (Dec. 12, 2011) — A major study of recent international data on school mathematics performance casts doubt on some common assumptions about gender and math achievement -- in particular, the idea that girls and women have less ability due to a difference in biology.
Don't look for widespread coverage of this study in the mainstream media. The MSM prefers stories wherein hard-nosed science finds that there are important biological brain differences between the genders. The narrative is then, "Why look, the old adage about 'snips and snails' vs. 'sugar and spice' turns out to be true, after all. Science proves it!"
The linked article above includes sidebar links to great stories related to this ongoing debate. The widely accepted stereotypes that boys are better at math while girls are better at language have no basis in biology.
