A few days ago I came across a blog by a woman who is clearly intelligent and is a feminist in the best sense, but she seems to be resistant to the idea that men and women may be different in their minds as well as their bodies.  http://www.rolereboot.org/culture-and-politics/details/2013-12-why-science-should-stop-trying-to-find-the-differenc

The writer was incensed by what she perceived as just one more attempt by males to marginalize and belittle the attributes of women by comparing them (unfavorably?) with those of men. This despite the fact that several coauthors of the study were female, and the qualities attributed to women in the article are highly valuable in our contemporary culture. This is the report that led to the angry response. http://www.theguardian.com/science/2013/dec/02/men-women-brains-wired-differently

We, as human beings, need to stop being so defensive–so eager to be in denial–about scientific evidence, and particularly about biological evidence. Scientific data should be inherently value-neutral. It is we who add the value to any interpretation of scientific results. It makes no sense denying the reality of things. Is the average world temperature rising or not? Are the polar ice fields melting? Yes it is, and yes they are. Those data are supported overwhelmingly.

It’s like asking whether or not the earth is round (O.K., spherical or eliptoidal, if you wish). It is what it is. It’s certainly possible, even desirable, to ask WHY something is as it is. And if it is an unpleasant reality, it’s certainly useful to ask if and how it can be changed. Indeed, that willingness to question reality–and to address it at its core–is the source of almost all human progress.

As with other differences between human beings, mental differences are broadly distributed, and no two brains are identical in composition or wiring (no, not even in twins). Moreover, brain wiring is highly plastic and is strongly influenced by environmental experiences.  But it is becoming increasingly clear that at least a large part (maybe not a majority) of mental functions find their origins in our genes. And these mental functions are reflected in behavior. I was struck one time when I heard a cousin laugh in another room and thought it was my brother. Those two laughs were identical in pitch and cadence. They were somehow wired to sound like that, and that wiring has some genetic component, probably like bird songs.

So I responded to her commentary with a long comment of my own, which will form the substance of the next blog post.
