I'm always surprised by the strong underlying assumption that removing interviewer/managerial bias will result in a gender ratio of 50%. There's research to suggest that this assumption is flawed: [0] Moreover, the idea that anatomy and physiology don't condition preferences or behaviors flies in the face of everything we know about human biology and (embodied) cognition. Let's recognize gender/feminist theory for wh…
You're the one introducing a 50% number, I haven't seen anyone make that assertion. There are structural problems that make the available talent pool unequal per-capita anyway (women being socially pressured out of software engineering, resulting in a lack of role models, etc. I'm sure there are plenty of other factors). Part of changing the dynamic will take decades because _currently_ a smaller percentage of all wo…
"Gender gap" is a fancy way of saying "not 50%". More to the point, assumptions are often unstated, as I'm sure you know.
I agree with you insofar as the mechanisms you point out are likely contributers to this so-called gap. Rather, I'm highlighting that -- unpopular though this notion may be in certain circles -- part of this effect is likely to be driven by bottom-up biological factors.
How big is this part? I haven't got a clue.
I'm copying my "tl;dr" from the above comment because it applies here as well: if we're going to have an honest debate, we have to entertain the notion that at least part of the gender gap is the result of "nature", rather than "nurture".
