Why There Aren't More Women In Tech: A Realistic Look at the Numbers

The amount of "men vs. women in tech" stories on HN is starting to be a bit ridiculous. If there were no such thing as social construction, and all people had the freedom to do whatever they want to do, how many people actually believe there would be an equal number of male and female computer engineers or helicopter mechanics?

In America today, I submit to you that women are at least as free to pursue their dreams as any other civilization in history. The article says CMU "began (a) campaign to enroll more women", so one could even argue that women have an advantage here in terms of recruitment.

I'm no sociologist, but isn't it even remotely possible that fewer women want to be computer engineers or helicopter mechanics?
