(following are purely my own opinions, nothing more )
I think it's good to do humanities studies but naive to latch on to one or two. Humanities is a messy field from a scientific perspective. But nevertheless there is plenty of signal there.
The issue I have is starting with something like 50/50 and then trying to optimize for that. This is invariably what happens. This leads to all kinds of weird, bizzare practices like being discriminatory in hiring based on (largely) immutable attributes like race and gender. The concept of gender itself is so in flux these days that it seems premature to start with 50/50.
This above approach I think is known as equality of outcome. I am not a big fan of that.
I personally think a better system is based on equality of opportunity where the optimization function should be trying to improve people's starting points. This is much harder but much better for the long term health of the society (in my opinion ).
In equality of opportunity, the hiring will be blind to gender. But work will be done to encourage more girls to participate in the sciences from an early age. Liberals wont be able to pat themselves on their backs immediately as they won't be fulfilling quotas quickly to show faux diversity. Corporations won't be able to bandage bad PR events quickly (like Google's gender paygap thing ) but this is in my opinion alot healthier over time.
Now, over time, I would expect the ratio to improve, but then settle at whatever is natural without any top down pressure to fulfill prescribed quotas. It might be the case that the mean of the distribution of women is closer to things like raising families or educating kids as teachers (the most important job in the world in my opinion ) instead of toiling away in front of a screen for crap money to make more money for a big corporation (compared to men).
In the first case (equality of outcome) we take two different distributions, men and women, and push them into a 50 50 split. In the second case (equality of opportunity), we try to move the means closer bottom up. I prefer the second approach. Slower, harder but much better for the long term health of society.
