I thought this was interesting, though hardly surprising. I find it quite a big concern given how much research we're constantly being shown, that 'proves' women are all [insert stereotype here]. This article looking at why so many women don't progress in academia - and in particular why mothers don't - perhaps gives a good reason why we might take some research with a pinch of salt: it's largely done by men and childless women.
