I think it has to do with low knowledge of statistics. The funny thing is that all the following sentences can be true at the same time: 1. Across the whole population, fewer women than men have the biological/psychological traits needed to become software engineers. 2. Female engineers are underrepresented in Silicon Valley and face many different forms of discrimination. 3. Female engineers at Google are on average better than their male colleagues. I'm not suggesting any of these sentences are necessarily true, just that they can be. This is not intuitive, unless you know a bit of statistics.
