See citation above. I'm saying its much too strong a claim to go from this paper to the conclusion that women are biologically less inclined to engineering.
EDIT: To be consistent with my original statement (see child)
You are losing this argument because you aren't being consistent with yourself.
Originally you said, "using these differences to conclude that women are biologically less inclined to engineering is a gross leap in reasoning"
So you were talking about inclination and interest. You then claimed the facts were on your side, that it was offensive to claim otherwise, and the existence of anyone who doesn't already agree is "unfortunate".
After chongli pointed out that you're wrong about the facts, you have moved the goalposts. Now you're pretending you said "biologically ill-suited". This is not true. You said "less inclined".
As the memo in question didn't claim women are biologically ill-suited to be software engineers, only less inclined, your original statement was contradicted by science and your second try is not what anyone tried to argue.
Nobody argued with the obvious fact that people expressed outrage and took offense at the memo. The argument started with your baseless claim that "women are biologically less inclined to engineering is a gross leap in reasoning that is not at all supported by the facts."
1). "Results provide strong support for hormonal influences on interest in occupations characterized by working with Things versus People"[0]
2). "Boys and men prefer occupations related to objects (e.g., auto mechanic, chemist), whereas girls and women prefer occupations involving work with people (e.g., day care worker, art teacher).[0]"
3). "Our results suggest that typical women, who are exposed to low levels of prenatal androgen, participate less than do men in STEM careers partly because they are interested in working with people. This is consistent with evidence that women value communal goals, which are perceived to be at odds with STEM careers (Diekman et al., 2010) and that women who enter STEM careers often do so in people-oriented professions, such as medicine (Benbow et al., 2000)."[0]
It's the paper that is concluding women are biologically less inclined to engineering.
I suggest you reread #3 and note the use of language like "suggest", "consistent with" and "perceived". Authors use language like this because its really hard to make definitive statements in this area. In addition, its really hard to quantify the size of the effect and how much is due to nature vs. nurture.
Furthermore, I'm relatively certain the authors are not experts on software engineering. As you have likely seen at this point, you could also claim that higher empathy actually should incline people to the job (see, e.g. https://medium.com/@yonatanzunger/so-about-this-googlers-man...)
