2:1 hiring advantage for women in STEM http://www.pnas.org/content/112/17/5360.abstract
As newmana mentions, there are issues with that study: http://othersociologist.com/2015/04/16/myth-about-women-in-s... And there are other studies I find more persuasive. E.g.: http://www.pnas.org/content/109/41/16474.abstract http://blogs.scientificamerican.com/unofficial-prognosis/stu... In particular, I think the "switch the names" sort of study under realistic conditions makes it clear that bias is an issue. And…
Most of this criticism doesn't stand up to even a cursory reading. For example: "not only are there less women in STEM fields [..]" No shit, Sherlock, I don't think anybody disputed that.
Or the study that shows a disadvantage for mothers vs. fathers. The very same study shows a hiring/renumeration disadvantage for childless men vs. childless women. So yes, there's a dynamic here, but it's not male/female.
Also, the original comment I replied to was that outstanding developers are overlooked. None of the studies I've seen that show gender/racial bias (there are a few), deal with outstanding candidates (the Wiliams/Ceci did, IIRC). And incidentally not sure why you refer to "studies", your two links refer to the same single study.
There was another study (I think it was a different one) touted as showing hiring biases in STEM, except it turns out the study was performed in psychology departments.
Etc. etc.
There's some great information out there on the web in case you are interested, for example the Pinker / Spelke debate. Here's a quote:
"PINKER: But that makes the wrong prediction: the harder the science, the greater the participation of women! We find exactly the opposite: it's the most subjective fields within academia — the social sciences, the humanities, the helping professions — that have the greatest representation of women. This follows exactly from the choices that women express in what gives them satisfaction in life. But it goes in the opposite direction to the prediction you made about the role of objective criteria in bringing about gender equity. Surely it's physics, and not, say, sociology, that has the more objective criteria for success."
