We need the best and most creative minds in our science fields. Plenty of men will argue that they don't know why women would need encouragement and that if they're interested in STEM fields they would just go into those fields. It is their privilege to think this way. We are a culture that values women's looks and men's accomplishments, and it starts at an early age (just check out magazines geared towards kids. The differing headlines from Boy's Life vs. Girl's Life are staggering). Obviously there is a lot that needs to be done to shift the cultural bias within this country, but one of the best ways to to do that is by giving more girls and women opportunities to rise in fields where they're underrepresented.
