The base of her argument rests on this:

"In fact, research has shown that cultures with greater gender equity have larger sex differences when it comes to job preferences, because in these societies, people are free to choose their occupations based on what they enjoy."

Jim Flynn's study has unequivocally proven that raising the standards of modern introduction and access to equal education, living standards, and nutrition show increases in overall propensity for cognitive achievement. Though, if you talk to an anthropologist the nature of the term "intelligence" and "cognitive ability" is used in the mixed usage term but says nothing of the nature of intelligence.

Nevertheless, the entire debate is whether we are actually in an egalitarian society to begin with. The nature of even measuring cognitive ability with the g-factor is that it is derived from relative populations. Gender differences might indeed be more amplified in these type of societies but the debate is whether we are already there and to what degree sectors of our large country have access to that.

I would argue, as others have, that the distribution of equal treatment, based on the evidence of exodus from the field of technology speaks far larger volumes about the industry as a whole than it does about biological differences.

Indeed, let's even take into account those biological differences that are being discussed here. Just because one has the propensity to behave a certain way in front a social group of men, and different when a female is around (this too has scientific backing), you could argue that the change in behavior over time would be a product of how distributed those groups are (in thought and in numbers). Food for thought.

It's also interesting to note that creative endeavors tend to lead to high correlations of neuroticism as well. If there are biological differences that show that women are, on average, tend to be more neurotic than men, it doesn't really say much about the nature of interaction or the way we behave with one another. Furthermore, to even attempt to use this as reasoning that women may not last within male-dominated environments is insulting in itself. What it really actually proves is that the inequality in both the diversity thought and in numbers only reinforces the problem. The logic is rot with flaws, (I'm paraphrasing several sections with lines of reasoning; i.e. de-emphasizing empathy) "due to the nature of the tendency for behaving a certain way, we should not make attempts at empathizing with one another because of the heightened sensitivity." Not only is this flawed logic, it's not scientific in the least bit. I would've fired him on that alone.

Indeed, you can also conclude from similar studies that creative endeavors have the tendency to being higher activity in the medial prefrontal cortex. (http://www.sciencedirect.com/science/article/pii/S1364661315...) Due to the nature of mulling over problems, the tendency is that this often is indicitive of a higher threat sensitivity (real or otherwise); hence the neurotism. This doesn't say anything about the gender differences therein, but rather the brain itself when it comes to problem solving in general.

Of course, the greater problem here is about the nature of social interaction. We can take into account how men tend to behave around other men, or in the presence of women, or women around other women, or in mixed groups; we can take into account innate differences (however pronounced or not); we can even take into account the debate over the access to a population which is educated enough to enter the field of study. Even taking into account the meta-analysis study on things-people, it is a bit presumptuous to think that parity is not obtainable or necessary in STEM.

The nature of STEM revolves around the problems that are being solved. One would hope that those problems are about solving them for PEOPLE. One would hope that software engineers employ creativity and artistic nuances when architecting and collaborating with others. The base of that study only speaks about the anthropologic nature of how people behave within those fields. One can speak of the people-oriented nature of mechanics, engineering, and just about all fields of study. I find it a bit simplistic to categorize STEM as a whole as purely mechanics; it's reductionist and frankly insulting.
