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 fraction of the warming observed on the planet.
Someone who wishes to debate honestly would admit that, while there are many factors that affect global mean temperature, the rise on CO2 concentration in the atmosphere is significant, and has a demonstrable effect on temperature, making it by far the strongest influencer.
Someone who wishes to debate dishonestly will use these other explanations as a method to muddy the debate and try and turn attention toward lesser factors that cannot explain the whole effect.
Now, if you look at this current "debate", yes, there are undoubtedly biological gender differences that can explain some male/female bias in engineering (among many other disciplines).
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.
So to claim those gender differences lie at the root of bias in the industry is a distraction. At best it's a gross misunderstanding of the science and statistics. At worst, it's a deliberately dishonest attempt to muddy the waters and confuse the debate. Personally, my bet is it's more the former than the latter.
