I was wondering if the difference in pull request acceptance rates by gender could be accounted for by the relative percent of profiles that are gendered for women versus men? You mention in the article:
...we see evidence for gender bias: women’s acceptance rates are 71.8% when they use gender neutral profiles, but drop to 62.5% when their gender is identifiable. There is a similar drop for men, but the effect is not as strong.
Converted into a null hypothesis: "Gendered profiles are more likely to have pull request rejected than gender-neutral, AND women are more likely to have gendered profiles than men - hence women tend to have lower acceptance rates than men."
I'd love to know what % of (outsider) profiles were gendered for both women and men. Thanks!
