Very interesting interview with two researchers into the affects of stereotypes on women in their performance in maths tests.
This is based on their study (pdf) published in the Journal of Experimental Psychology.
See I'm not just wittering on about gender stereotypes, be they a love of pink or the *need* for women to remove every inch of hair from their body, because I find them irritating (physically and mentally); they can also be harmful.
And immensely aggravating to those of us who can long divide. Again, I give you xkcd on this subject.
