There is a constant dissonance in the western world between assumptions about "ideal" or "moral" statistical probability distributions and actual statistical probability distributions over a large sample size when it comes to any politically sensitive topics like the one implied in the article (i.e women having an interest in science and technology).
This happens over and over again. There are thousands of articles a year on this kind of thing and millions of human years spent mulling why the ideal curve doesn't match the actual curve. It's the perfect topic for non-productive rambling because it's always dissonant and it never goes anywhere.
The dear reader probably already knows this, but to the idealist, the ideal always equals the actual in a just world and evidence of a mismatch is evidence of injustice. Those who accept or tolerate the actual not matching the ideal are presumed to support injustice.
These arguments are endlessly repeated. Nevertheless, seemingly endless repetition is a very effective means of political discourse. I realized this most profoundly when studying religious texts. Points that are intended to be remembered are mentioned over and over again to the point of mind-numbing boredom. Repetition is good for remembering and people only believe what they can remember. Thus the most effective strategy of any activist is to repeat their message over and over again and have the adherents do the same and approve the same and ostracise those who criticize and those who don't care, thus spreading the idea through the society via social psychological principles and the pure intellectual brute force of repetition.
