- Women in open-source are more competent than men? This is the hypothesis that the authors support the most. They suggest it somes about due to survivorship bias and/or self-selection and/or higher implicit performance-standards in the female population of open-source coders.
I would assume the survivor selection bias thing.
the common core scam (which is incompatible with logic-based mathematics), kids can no longer fail regardless of performance
Common Core tests have a high failure rate because of the much higher goals. You're conflating so called "Common Core curriculum" which is sold by private companies with the standardized Common Core progression benchmarks. Any test can be "Common Core" as long as it closely aligns with the Common Core benchmarks. How the tests are done or how the curriculum is taught has nothing to do with "Common Core" except marketing.
