How women should ask for a raise

Effects of prenatal exposure of phthalates in boys
A new study in the International Journal of Andrology has raised a storm of concern that prenatal exposure to these chemicals could make boys less masculine in their play preferences.
Phthalates, which block the activity of male hormones such as androgens, could be altering masculine brain development, according to Shanna H. Swan, a professor of obstetrics and gynecology at the University of Rochester Medical Center and lead author of the new report [Los Angeles Times]. To test whether that link extended into behavior, Swan’s team tested women for phthalate levels midway through their pregnancy and then checked back in on the children four to seven years later.
The researchers asked parents to report their children’s patterns of play, but they knew they also had to separate any potential phthalate effect from the “nuture ” side of question. To determine how parental views might sway behavior, parents completed a survey that included questions such as, “What would you do if you had a boy who preferred toys that girls usually play with?” They were asked to respond with whether they would support or discourage such behavior, and how strongly [TIME].
The study of about 150 kids found that while girls were mostly unaffected, boys who had been exposed to the highest phthalate levels showed a lower likelihood than other boys to participate in what we consider typical rough-and-tumble male recreation—play fighting, pretending to play with guns, and so on. But the research might not imply the national masculinity crisis that some headlines suggest. Play in the most highly phthalate-exposed boys wasn’t “feminized,” Swan explains, since these kids didn’t preferentially play with dolls or don dresses. Rather, she says, “we’d describe their play as less masculine” [Science News]. Rather than play-fighting, she says, those boys tended toward “gender neutral” play like putting puzzles together or competing in sports.

Gender in the brain
Excerpt: "At first glance, studies of the brain seem to offer a way out of this age-old nature/nurture dilemma. Any difference in the structure or activation of male and female brains is indisputably biological. However, the assumption that such differences are also innate or “hardwired” is invalid, given all we’ve learned about the plasticity, or malleability of the brain. Simply put, experiences change our brains....
"...[For example] If the sex difference in the straight gyrus (SG) is present early in life, this strengthens the idea that it is innately programmed. Wood and Nopoulos therefore conducted a second study with colleague Vesna Murko, in which they measured the same frontal lobe areas in children between 7 and 17 years of age. But here the results were most unexpected: they found that the SG is actually larger in boys ! What’s more, the same test of interpersonal awareness showed that skill in this area correlated with smaller SG, not larger, as in adults."
Here is Rafe's response to the article:
This article is terribly written, with ridiculous assumptions.
The first one - "On the other hand, sex differences that grow larger through childhood are likely shaped by social learning, a consequence of the very different lifestyle, culture and training that boys and girls experience in every human society."
This is patently ridiculous. Virtually all sex differences grow larger with age as males and females diverge hormonally. Obviously we wouldn't use culture to explain the accelerating gap in height and mass, or bone structure or secondary sex characteristics. Even gaps in things like aggression and neuroticism increase with age to peak in the early twenties before coming more in line with each other as we age beyond the 20's.
Secondly, "Individuals’ gender traits—their preference for masculine or feminine clothes, careers, hobbies and interpersonal styles—are inevitably shaped more by rearing and experience than is their biological sex."
This is just wishfull thinking. There is no experimental evidence to support this; essentially we are just talking about two sides of the same coin the masculinity or feminity of the body vs. the mind. Both are largely genetic, we just don't fully understand all the mechanisms.
It pisses me off that they have to frame every story about this like somehow culture is the good guy riding in, that we can't write it off, it might just save us from the big bad genetic bad guys after all. It's editorializing and literally twisting the actually meaning of the study backwards, the important lesson of that study is yet another consistent and persistent cognitive difference between the sexes but they try to make it seem ok by implying it really all might be cultural.

What she wore
Okay, I'm not going to try and be a post-modern type and say "oh, it's all relative, we need to be accepting of other people's cultures." Bull. Burning down a woman's house and stripping her naked because she's wearing pants is horrible and I can't believe people don't get more pissed off about this sort of thing. Even the article's author has this attitude of, "oh, well, she was living in a men's neighborhood, she should have known better." No, no, no! That sort of behavior is inappropriate in any society.
I know this is an extreme case, but even in 1999 the Italian Supreme Court of appeals ruled that a woman's rape was excusable because she was wearing jeans: http://news.bbc.co.uk/1/hi/world/europe/277263.stm, so obviously it is still known to happen. This sort of "she/he was asking for it" mentality is just wrong regardless of gender, regardless of culture, regardless of religious beliefs. Period.
