My goal was only to point out that Scott's article missed the substantial effects of affirmative action in law and medicine. I find any theory that doesn't account for the reduced sexism in other fields unsatisfactory. I haven't taken it any further than that; it seems unlikely that I'd come up with something useful.

If you are interested in this area then I would recommend reading the book Why Aren't More Women in Science?. It has 15 essays by experts debating the issue.

rayiner, a HN lawyer, also has some good posts that discuss affirmative action in law (https://news.ycombinator.com/item?id=21775576) (https://news.ycombinator.com/item?id=6875443).
