I thought about that after I wrote my comment. I only had them for one year in high school, so it's possible that they were subjected to years of other conditioning.
But, really, I have seen the exact opposite. Girls are actively encouraged to participate in math and science from a very early age in a lot of our schools.
I don't have any numbers on hand, but there seems to a drastic change in middle school where girls stop being interested in math and science. So by the time they get to high school, it seems like the fight for their interest is already over.
This is just my experience from being in education for several years.
