And for the record, that doesn't mean I like the result. I just think we need to look at this as a systemic problem and address it as such.. not blame the people at the end.
For example, my undergradate engineering school adopted a bunch of Girl Scout troops to encourage and grow interest in STEM. It has taken years but female enrolment has increased by 50%.. and they're not just shuffling from other schools. They're growing the pool of qualified candidates.
