Female coders are rated more highly than men, when nobody knows they're women

The drop in pull request acceptance from gender-neutral to gendered is worse for men than for women. (Figure 5) Anyone can cherry-pick parts of that preprint to support their argument.
I don't think (many) people are willfully biased, but every study bears out that bias exists. Make selection blind to race, sex, etc., and the results are different. Orchestras switched to blind interviews and hiring profiles changed dramatically. Suddenly females and minorities were rated higher and got more job offers.
Its sad, but true, that we have this unconscious bias and we need to fix it. I don't discount the conscious biases that clearly exist, I'm just saying a claim of "I'm not biased, my hiring is fair" needs to be backed up with data, not assertions.
"One explanation is survivorship bias: [...] Another explanation is self-selection bias: [...] Yet another explanation is that women are held to higher performance standards than men [...]"
Or in other words: Women who stay long enough to end up submitting PRs submit higher quality code, while the much bigger population of men, under much less social pressure, has a more well-distributed quality curve; and even women who get this far are biased against if their gender is known.
And then you discover in Questions Section; "Our analysis (not in this paper -- we've cut a lot out to keep it crisp) shows that women are harder on other women than they are on men. Men are harder on other men than they are on women." https://peerj.com/questions/2002-do-you-have-data-on-the-gen....
