"“What this research shows is that the image of computer science — this geeky, masculine image — can make women feel like they don’t belong,” says lead author Sapna Cheryan of the University of Washington."

Uh, no, actually. It's not the decor or image that's the problem, it's the attitudes and behavior of the men who inhabit such spaces. Frankly some of the worst misogynists I've met were self-proclaimed "nerds" and not just the stereotypical jocks generally associated with such attitudes. Not all or even most geeky guys are sexist but enough are that any college-aged woman in a room full of them without any other female compatriots is going to potentially feel uncomfortable or threatened.

Personally? I'm a woman. I love Star Trek. And video games. And super hero comic books, manga/anime, computers, "hard" sciences and all other manner of geekly pursuits. There are TONS of girl-geeks in this world, they just tend to get ignored by the boy-geeks because girls apparently have "cooties" or something.

I got my B.S. in Geology and that was hard enough, I was in several classrooms with a load of men and no other women and it wasn't always fun. I stuck with it because I'm a stubborn ass, there were a couple other equally stubborn women in the major but we were far outnumbered and it wasn't always an inviting environment.
