Do you have a citation for the interest of girls in STEM? And also, especially, citations about the peer pressure? Not my experience from High School - in my Maths class, there were only 3 girls out of 16 pupils. When I was in school, there was also nobody being encouraged to pick up Computer Science. Boys were into computers despite the disdain by society, peers and parents. On a scale of 1 to 10, how attractive did being into computers make you to girls in High School? Also, much is being made of the performance of girls in High School Maths, but let'S be honest, Maths at school often is not really Maths, it is calculating stuff. So it is perhaps not the ultimate measure. Also, significantly more women than men study Medicine or Biology - somehow they don't seem to count as STEM? Why not? Given the choice between Medicine or Computer Science, I am not even convinced that Computer Science is the better choice in the long run. My stance has always been that women are too smart to choose CS - they shun the long hours in front of a screen in a windowless basement, devoid of daylight and human contact.
