I'm just gonna copy another comment I made elsewhere: The problem is that the gender differences cited cannot, in aggregate, explain the 70/30 bias toward men in the industry. There's a real similarity to the global warming debate, here. There are many factors that affect global mean temperature. For example, over the very long term, the sun will get brighter. But that can only account for an astonishingly tiny fract…
> But no serious psychologist or sociologist would claim that those differences can account for the dramatic real world bias in the industry. It simply doesn't follow. What's your evidence for this? Debrah Soh, the author supposedly has a PhD in sexual neuroscience so one would think she is qualified to make comments about this. And although I can't confirm this myself, the article does say that societies with greate…

The article points out that for most of the biases cited in the memo, the differences are on the order of a few percentage points, which cannot account for the real-world outcomes we see. To quote:
Still, I think it's important to keep in mind that most psychological sex differences are only small to moderate in size, and rather than grouping men and women into dichotomous groups, I think sex and sex differences are best thought of scientifically as multidimensional dials, anyway (see here).
To be honest, I'm not sure how Ms. Soh can seriously argue the merits of the memo, here. Yes, technically the memo is not itself inaccurate, in that there are gender biases that result in practical population-level effects. But how one can seriously use those facts to conclude that the 70/30 population split in the valley is a product of those differences, I really don't know, unless confirmation bias is at play. It just doesn't make any sense.
Heck, just looking historically it doesn't follow... it's not like the biases we see are inevitable. Our industry used to have a different composition. And other STEM fields have seen gender disparities even out. So neither facts nor history support the conclusion.
