After reading this article, I have to reserve judgement. There aren't specifics yet, just people who I am interested in listening to and wish to hear more from. We may come to know eventually, but we don't know yet.
They won't consider how much you "demonstrated interest" in CS to get into the program. https://news.ycombinator.com/item?id=17446996 [Edit: this isn't only for the CS program, and it's not only about women, but you can fill in the blanks I guess]
I think it makes sense if you think women (IIRC this was about the gender gap in CS) tend not to be directed toward CS as much as men are in middle/high school, or if you think their accomplishments might have been downplayed or not played up as much due to someone else's sexism. After all when you're recruiting for college you don't care so much about a person's past accomplishments so much as future potential.
