The article does not accomplish that. Despite an overall trend in STEM throughout the western world for greater male participation than female, computer science is uniquely low; it is rivaled only by physics and MechE for gender disparity.
Throughout the rest of STEM, including hard fields like chemistry and mathematics, we see significantly improved participation among women. There are a bunch of STEM fields that have near parity, and a few (molecular biology, for instance) in which there are slightly more women. These are PhD numbers, not premed stats.
Besides better gender parity, something all these fields have in common at the graduate level is that they are significantly more demanding than commercial computer science. We kid ourselves that our day-to-day work is so rarefied that we need the top of the intelligence curve, so much so that the supposed variance in intelligence between men and women might explain our staffing. That's ridiculous. We do a bog-standard symbol manipulation job, and, even at the elite level, we tend to do it slap-dash and ad-hoc.
Whatever is keeping women to 20% of our field is artificial, and a travesty.
It's also on the front page, I believe, because it's a cite followed from an article posted earlier this week making some of the same arguments. That post had a huge discussion, making this a needless duplicate. We don't need to keep re-litigating this on the front page of the site. I flagged it.
