No, it has nothing to do with brain size.
I think that was already implied in my above statement.
We know that there is a correlation of brain size and "intelligence" (loosely defined) but no causation. Further, gross neuronal brain structure doesn't matter. We actually have the highest number of neuronal connections at age 3, by age 5-6 they've been vastly pruned down, at which time we are much more highly developed. I don't think you'll find the answer by looking at how many neurons, and at any rate high intelligence isn't a prerequisite to do well in STEM.
The study above suggests structure does matter.
Yes, neuronal connections are trimmed down, but this has nothing to do with the point regarding female/male brain structure.
I wasn't looking at the number of neurons, I was pointing to structure.
I did not state high intelligence as a prerequisite for doing well in STEM. I was addressing Duxwing's point about male/female GM ratios.
It's simpler than that in my opinion. People know that men are driven by their biology, we make jokes about how men have to have lots of sex. People don't talk much about women. From a lifetime of observing women at many ages I think it's clear that women are far more controlled by their biology than men are. Further, MBTI tells us (and it's obvious) that 75% of women are F types.
It is not that simple, as the study above indicates.
The phenomenon of men talking about sex more than women is an assumption from a male perspective (and some women who may come from more traditional social backgrounds). I may as well say the same thing based on my perspective: women talk more about sex than men. Either statement may be true or false depending on culture/experience/personal bias/social group composition, etc, etc.
Even if that was the case, that men do
talk more about sex, it does not imply that women aren't just as
preoccupied with sex. I mean, men have to be manly, right? So they must talk about sex to show it. Cultural conditioning has taught women to be less explicit, however (we can thank the church for that) What goes on in their minds needs to be assessed by observation and extensive surveying across many cultures, and then perhaps, can we make more definite statements about male/female sex preoccupation. Also, your observations are based on a culture different to others. Keep that in mind.
If we are going to have a discussion based on personal experience, we may as well give up now. Making generalisations based on one's own subjective framework is not very scientific.
Also, the F-types in the video above reveal very strong and confident subjects. I don't see why being an 'F-type' should be an obstacle to getting into STEM; in fact, I think we need more F-types in STEM as they seem better equipped to deal with the more ethical sides of research methods, particularly in areas such as medicine and animal research.
Like it or not, evolution has rigged the game against women, far more than against men. Men have a short term commitment to biology (just gotta have sex), women have a long term (bear and raise a child). I think this predisposes women against STEM.
That is not an argument against women going into STEM. Evolution is a constant, and roles are slowly changing. One could even argue that the human preoccupation with women's rights is an evolutionary vector. It is part of what we call progress. If a woman chooses to go into STEM, it is probably because she actually wants to. Yes, she might make the sacrifice of having less opportunities for family building, but many women now choose careers over family life. This is not 'unnatural' as it is as much part of human progress as any other aspect of human evolution.
Personally, I wish I had been in a STEM program because my social indoctrination that women aren't wired for hard sciences almost took away my confidence. My own mother (who ironically happens to have a calculator for a brain and is something of a maths freak) told me that girls don't do well in maths, for example. Perhaps she was trying to protect me, I don't know. My maths teacher mocked the girls openly in class as being less inclined to understand the concepts -- all the while attempting to get into one of the girls pants during a school camp. During my school days I was constantly fed crap from males in my school that girls can't do maths and should stay at home and cook, etc. Luckily I did not listen to them, but after a while doubt does start to haunt one's rational faculties. It is called social indoctrination of gender stereotypes.
I think these factors greatly contributed to put me off going for a science career, but through sheer will I got my confidence back and put myself through it. And guess what? Because I
wanted to.
For the above reasons, there have been studies attempting to get to the core issues of why women are discouraged, and how this could be amended:
There are studies that show girls do much better academically when segregated from boys, and vice versa. Please see links below.

The cultural differences seem to be evident here:
All-Subject Achievement Test Scores
Traditionally, all-subject achievement test scores have been defined as scores indicating the composite mastery of specific skills or scholastic content areas (i.e., mathematics, verbal, science, etc.) acquired overa restricted span of time (Murphy and Davidshofer,2001). Of the nine studies that examined the relationship between type of school and overall all-subject achievement test scores, six (67percent) reported results supporting SS schooling, two (22 percent) found null results, and one (11 percent) reported results supporting coeducation. When comparing SS and CE for girls, five of eight (63 percent) studies reported results supporting SS schooling, one study (13 percent) reported null effects,and two studies (25 percent)reported results supporting CE. When comparing SS and CE for boys, three of four studies (75 percent) reported evidence in favor of single-sex schooling and one (25 percent) reported null results. All nine studies examined the impact of single-sex schooling versus coeducation using high school samples. Only Garcia (1998) and Riordan(1990) examined the relationship between ethnicity (African American, Asian, or white) and SS schooling versus coeducation. Despite finding differences favoring coeducation for all three groups, the author reports null differences between SS and CE students when controlling for preexisting differences among African Americans and Asians. In the case of white students, the differences remain even after controlling for preexisting differences.
Riordan (1990) did report significant difference among whites, African American, and Hispanic students in SS schools and those in coed schools."

If true then the question is should we so actively proselytize women to get into STEM? Doesn't that send the message that we think STEM is more important than anything else you'd care to do?
Proselytize is a strong word. The program is there for a reason. Many women feel discouraged from entering male dominated fields right from childhood; programs like these may help those individuals who have lost their confidence.
