Andrew Sullivan And The Feminist Rejection Of Nature

Andrew Sullivan has a fine new column in New York magazine's website that deserves attention, about the nature of being male, and how nature — or perhaps, more fittingly, Nature — is not to be denied:
... [I]n the years of being HIV-positive, my testosterone levels had sunk, and I decided, given my lassitude, depression, and lack of sexual desire, to go on hormone replacement therapy to get me back in a healthy range for a 30-something male. It was a fascinating experience to witness maleness literally being injected into me, giving me in a sudden jump what had been there all along, and what I now saw and felt more vividly. You get a real sense of what being a man is from an experience like that, as the rush of energy, strength, clarity, ambition, drive, impatience and, above all, horniness overcame me every two weeks in the wake of my shot. It was intoxicating. I wrote about this a couple of decades ago, in an essay I called “The He Hormone.” The visceral experience opened my eyes to the sheer and immense natural difference between being a man and being a woman, and helped me understand better how nature is far more in control of us than we ever want to believe.
Sullivan goes on to observe that it is now "taboo" to discuss naturally occurring differences between men and women, particularly ones with demonstrable biological origins. The belief that such differences are not inherent but socially constructed are a fundamental tenet of much modern feminism, gender feminism particularly. Steven Pinker attacked this in The Blank Slate in 2003; it has made little difference in the academy, and in lay feminism. "It is strikingly obvious", Sullivan continues, "that for today’s progressives, humans are the sole species on this planet where gender differentiation has no clear basis in nature, science, evolution, or biology. This is where they are as hostile to Darwin as any creationist."
If most men are told that what they are deep down is, in fact, “problematic” if not “toxic,” they are going to get defensive, and with good reason. ... And men, especially young men in this environment, will begin to ask questions about why they are now routinely seen as a “problem” ....

This week, in the New York Times, Tom Edsall bravely exposed the politics of this. He looked at the data and found, believe it or not, that gender-studies feminism is not shared by all women by any means, and is increasingly loathed by men — and not just older men. “2016 saw the greatest number of votes cast by young white men in the past 12 years — markedly higher than their female counterparts,” says Kei Kawashima-Ginsberg, a psychologist at Tufts.
... Trump understands this dynamic intuitively. Bannon believed it was integral to the Trump project, and wants the slanted elite discourse on men to continue and intensify. I think this issue was an under-acknowledged cause for Clinton’s failure. At some point, Democrats and liberals are going to have to decide if they want to “problematize” half the voting population.

The recently deceased Ursula K. Le Guin populated an entire world with an androgyne race in her novels set in the Hainish universe. That was fiction, of course, but feminist theorists who start every explanation of male behavior with "men are taught to..." apparently believe we live in such a universe. Certainly Laurie Penny, who can be counted on to ignore every major point Sullivan made, has not disappointed in that regard, and neither Jessica Valenti's impressively lazy response.

Meantime, we have an election later this year. It will surely be interesting to see who shows up for it.

Jerry Coyne Reviews Cordelia Fine's Testosterone Rex

Pretty much what you'd expect, leaving the deets to Stuart Ritchie's review.
Before I started TR and then while I was reading it, I wrote two posts (here and here) about Fine’s claim that there’s no evolved differences in male and female behavior. I also criticized her completely muddled and erroneous claim (based on bogus statistics) that sexual selection doesn’t work because the “Bateman experiment”—showing a greater variance in reproductive success among male than among female fruit flies—was wrong. Well, it wasn’t wrong, it was inconclusive, and later work, as Ritchie notes, has supported the sex difference in reproductive-success-variance that’s a crucial assumption of sexual selection. Bateman’s result was just a one-off that tells us nothing. Sexual selection is alive and well, and supported by tons of data. Nevertheless, Fine’s argument, which is really dumb if you know even a bit of biology and math, persuaded many people, including a Guardian reviewer, and Ritchie takes it apart in his review.
In that second link (which I missed earlier), Coyne quotes a review by the politically-motivated P.Z. Myers ("Myers has always rejected biology that is ideologically unpalatable to him"):
In a rare occurrence at his site, the commenters, usually a choir of osculatory praise, gave him pushback. In fact one,  “Charly”, did the math correctly and showed that males in relationships with multiple females (bigamous or polygamous) have the potential to have more offspring than do monogamous males, supporting the ideas that men are selected to compete for women. (Duh!) Charly ended his calculations with this statement: “But maybe my reasoning and math is wrong, I am sure someone will point flaws out.”

In the next comment, Myers admitted that Charly’s math was actually right—math that invalidates Fine’s argument—but then he said this:



And there we have it, ladies and gentlemen, brothers and sisters: an admission that the biology is right, at least in theory, but the person who did the calculations is immoral.
This is what we're up against.

Cordelia's Not-So-Fine Book Testosterone Rex Wins Royal Society Prize

No, seriously, Cordelia Fine's Testosterone Rex won the annual Royal Society science book prize.  Fine staunchly advocates the blank slate theory of human sexual differences, i.e. that cultural norms drive behavioral and other visible differences. That Fine's book is the purest tosh has been addressed elsewhere, as for example West Hunt's long-form review, Stuart Ritchie's review in Quillette, or Jerry Coyne's criticisms.  She botches her analysis of, the subsequent meaning of, and corrections/improvements to Angus Bateman's groundbreaking fruit fly research in the 1940's. She ignores research on congenital adrenal hyperplasia on other mammals, including among our near evolutionary cousins, the great apes. (Girls born with this condition secrete unusually large amounts of testosterone, and exhibit more male-typical play.) Ritchie notes that she elides significant criticism:
This fits into a pattern: evidence contrary to Fine’s position is often cited, but it’s not mentioned in the text, instead being relegated to endnotes where it can’t cause too much trouble. Witness, for instance, Fine’s mention of “stereotype threat”, where a single supporting study is discussed in the text but a contrary meta-analysis is only mentioned in the endnote. Or her discussion of a 2015 paper on how males’ and females’ brains aren’t essentially different, but are a mosaic of features: you wouldn’t know that four strong scientific critiques of the study had been published (with a response) unless you flick to the back of the book. This allows Fine to use the main text to critique only the most overblown claims about sex differences, and avoid having to deal at length with more reasonable arguments. of "stereotype threat": "a single supporting study is discussed in the text but a contrary meta-analysis is only mentioned in the endnote".
It seems foreordained that this award will serve as a significant data point for the notion that politics has corrupted the academy. Or will it? The panel issuing the award consisted of
  • Richard Fortey (paleontologist, committee chair)
  • Naomi Alderman (novelist)
  • Claudia Hammond (broadcaster, writer, social psychologist)
  • Dr. Sam Gilbert (brain researcher)
  • Shaminder Nahal (broadcast TV editor)
That is to say, it is predominated by non-scientists. How this might have happened would prove an interesting story, but it is not the same thing as a vote by the bulk membership (as with the Hugo Awards). Yet it points in a disturbing direction, cloaking badly-executed science with the imprimatur of the Royal Society. I hope this draws a strong reaction from actual biologists.

A Useful Summary Of Evolved Sex Differences In Animals

It's pretty rare to hear the words "feminist" and "evolutionary biologist" in the same sentence, let alone about the same person, but Suzanne Sadedin apparently wears both labels. She recently contributed a very good bibliography and summary of evolutionist thought on sex roles as they appear in nature at Quora. Excerpt (edited to add hyperlinks for footnotes):
  • Men and women are very similar neurologically, and the distributions of gender-correlated traits fall on a continuum; hardly anyone has a purely male-like or purely female-like brain [2]. Some brain areas are a bit larger in men, some in women. Overall brain size is larger in men, but in similar proportion to body size [3].
  • There are no consistent gender differences in average IQ, though male variance is higher [4]. Sex-specific differences in certain abilities tend to show up in studies [5], but can often be eliminated by avoiding certain biasing cues [6].

    ...
  • The term patriarchy, as used by contemporary feminists, often seems kind of meaningless. I think when we talk about patriarchy, what we’re really getting at is the re-emergence of social hierarchies that resulted from sedentary farming starting around 10K years ago. Individuals in sedentary communities were better able to control and monopolize resources, including women. This led to greater specialization, technological innovation, and social inequality [15].
 The comments range from interesting to hilarious to predictable; the many people claiming that looking to nature, and especially, to our near relatives among the great apes is an example of "the naturalistic fallacy" amounts to a hand wave. (Look, guys, if you're going to bring up outliers like bonobos, or animals far removed even from mammals like the angler fish and passerine birds, maybe your argument isn't that strong.) I disagree — in some cases, strongly — with her conclusions, especially depending on what her definition of sexual equality would look like. One that doesn't take into account evolved preferences (e.g. the perverse results in Sweden where strong child-care and time off guarantees have resulted in the most sex-segregated labor pool in the OECD) and abilities ("male variance is higher" in measured intelligence is a Clue) will produce an unachievable definition of equality, as witness the chimerical wage gap. Overall, the title piece is a good survey, and something I'll be coming back to again.
