There's something about all this that I'm struggling to put into words, but I will try...
It's broadly to do with the idea that in order to suceed, women are expected to "become like men" (that is, adopt traits traditionally ascribed to males) rather than their own feminine traits being valued. (*Leaving aside the nature/social conditioning issue.)
So... almondpudding But if it is the case, and the rate of girls going into STEM careers remains low, and they continue to follow arts/humanities heavy educational routes from 14 onwards, then women as a group will be left behind in economic, political, social and cultural spheres.
... Why do STEM subjects matter more to economic, political, social and cultural life? Is it by any chance because the world as we know it is designed and run by men? When you look at the world, and think about how to solve its problems, isn't nurturing, gentleness, co-operation etc. what is clearly lacking? Figuring out how people tick, doing something to reverse the increasing numbers of mentally ill people (psychology, sociology), caring for the increasing elderly population (care, nursing, communities looking out for each other), not willy-waving warmongering...
It strikes me that where science and technology are important, is in solving problems originally caused by masculine competitive overconsumption, and other problems that could be sorted out from a sociological point of view (eg. why the hell certain places have various diseases, don't have clean water, food etc. - they could do, it's just power and money that is the issue. Do we need drought-resistant crops, or do we just need to learn to share?).
It all just seems to lead back to the issue of what's valued, and it strikes me it's usually not the valuable stuff!
