Gregory Cochran reads Cordelia Fine, so you don't have to

Bad ideas never seem to go away. At least not the ones that the left likes. And the idea the left likes most of all is equality, and not some silly right-wing equality before the law, or equality of opportunity, either. The leftist idea is that all people are equal, period. That's all races, all ethnic groups, all religious groups, and both all 31 sexes. And since all such groups are equal in ability, temperament, yadda yadda yadda, when they don't have an equality of performance, that means somebody is discriminating against or oppressing somebody, of course. And the cure for that is massive government expenditures to equalize outcomes, and equally (heh!) massive numbers of regulations to punish everybody who doesn't cooperate fully.

This is an example of the "I f*cking love science" faction of the left. You see, guys (and girls) in lab coats carrying clipboards around have scientifically determined that unlike practically all other mammals, which, if they're distributed very widely at all across the world, have separated into subspecies that average differently in intelligence and other environmental adaptations, human beings haven't done that at all. Races don't exist, of course, and they're all equal anyway. Being separated on different continents for tens of thousands of years didn't affect people at all, because they're mysteriously immune to evolution. And they've also proved, somehow or another, that the human sexes (however many there are) are also totally equal in every way. I know they don't seem equal, and are physiologically distinct in many more ways that the obvious ones, and that their brains certainly look different, and that the sexual stereotypes of men and women have been pretty much the same for centuries and seem to mirror reality very closely.
But never mind all that. A feminist says otherwise, and Gregory Cochran [link] reviews her book:

Old T-Rex

I’ve just finished Testosterone Rex, by Cordelia Fine. In this book, she argues against the existence of innate psychological differences between the sexes. She does not want her readers to believe that men and women have different natures – apparently because such differences, or belief in their existence, would prevent social equality of the sexes. Personally, I think the more important question is whether it’s true. But I would say that, wouldn’t I?

Rather than talk much about differences between the sexes, which would do her case no good at all, she talks about testosterone’s role in creating such differences. Testosterone is a strawman theory, here. Sex differences might be caused, in part or in whole, by biological factors other than testosterone: would disproving an incorrect testosterone-based theory make the differences go away? On the other hand, it might confuse people enough to reduce or eliminate belief in such differences. People are fairly easy to confuse.

Sex differences can be pretty big. Men are about 8% taller, but they have 90% greater upper body strength (about three standard deviations) and 65% greater lower body strength. They run faster, jump higher. Teenage boys routinely beat professional female athletes, as when the Newcastle Jets U-15 team recently defeated Australia’s national women’s soccer team 7-0.

There are psychological differences as well. Boys prefer rough-and-tumble play, girls prefer ‘intimate theatrical play’. Boys and girls have different toy preferences: boys like trucks, while girls prefer dolls. Interestingly, we see similar sex differences in play in other young primates, such as vervet and rhesus monkeys. Young chimpettes are known to carry a stick around, sticks that seem to be stand-ins for future babies – like dolls. Since other primates that are not exposed to anything resembling human socialization [they can’t talk] show similar play preference patterns, socialization is unlikely to be the driver of those patterns in humans, no matter how much Fine would like that to be the case.

Girls with congenital adrenal hyperplasia are exposed to high levels of androgens before birth: their play styles are more like those of boys, and they (like boys) are better at spatial rotation tests than other girls. Fine suggests that CAH girls are socialized differently [due to their medical condition] , and that this may account for their boy-like play preferences. The female offspring of rhesus monkeys treated with testosterone during pregnancy also show male-shifted play preferences, such as tough-and-tumble play. Similar effects are seen in rats. Socialization is powerful !

Men are far more violent than women, far more likely to commit murder [and suicide], in every society. Obviously, if we see it everywhere and everywhen, the cause must be … climate change.!

Men take more risks, especially after puberty. Fine attempts to talk this away, as she often does. Her
argumentative approach sometimes has a certain mad charm, as when she mentions her baby son rolling across the room to a power drill, juggling knives, and trying to plunge a running hair dryer into the cake mix. I guess that no truly educated person could believe in anything so obvious, so… She also steps up to ” No true Scotsman “. She defines what must be the only correct definition of a risk-prone personality – someone that tends to embrace every possible risk – and if those correlations aren’t perfect, how could there be such a thing as a risk-prone person? She reminds me of Donald Rumsfeld, trying to define away the insurgency in Iraq by explaining that real guerrillas must have a unified doctrine and central command, which would have been a surprise to the raggedy-assed Spaniards fighting Napoleon, the men that gave us the word.

But crypts don’t lie. Teenage boys are twice as likely to die in accidents: you don’t see girls climbing down into the bear pit on a dare. To be fair, you don’t see boys do it twice. Young men are more likely to get killed making nitrogen tri-iodide, climbing Half Dome, or stealing copper from power lines. They can do it in a car, they can do it in a bar.

Almost all men are sexually interested in women, and the overwhelming majority of women are sexually attracted to men. I’ve heard that there are parallels in the animal kingdom. When you think about it, it makes a twisted kind of sense. Isn’t that a psychological difference?

Moderate differences in the average value of a trait can drive big differences out in the tails of the distribution. Men are only four or five inches taller than women, but all the tallest human beings are male. Men have a moderate edge in spatiovisual processing, but are overwhelming dominant – 100-1 – in the uppermost reaches of mathematics and science. Not just due to visuospatial differences, but that’s part of it. This also shows up in pool, which is not very dependent upon strength, but where the top men are much better players than the top women. Men’s advantage in spatiovisual skills likely plays a part in this. Jeanette Lee, when she was the top women player, said that there were ‘dozens of male players who could wax me.’ And, probably, even more that would have liked to.

Sexual differences are driven by selection favoring changes in one sex that lead to increased reproduction. This must explain men’s strength advantage, a product of competition with other males. Selection is the ultimate cause of psychological differences between the sexes, as well.

Generally, sexual selection is strongest in the sex with the greater reproductive variance. Usually, that means males – some have many offspring while others have few or none. Female reproduction varies less. Fine discusses a series of experiments by Angus Bateman [published in 1948] that led to claims of higher reproductive variance in male fruit flies. There were problems in those experiments – mistakes, technical problems and limitations. Some of the mutations used to trace paternal identity interfered with fitness and thus buggered the statistics. We wouldn’t have to use such a sloppy procedure today, but hey, it was 1948 – they didn’t even have the human chromosome count right. Yet similar studies have been done more recently on many other species – without those problems – and Bateman’s principle, that females are the limiting factor of parental investment, is generally true. Male reproductive variance is generally higher. So how does criticism of errors in a pioneering study refute a now-proven idea? That would be like claiming that Otto Lilienthal’s glider crash, where he died saying “sacrifices must be paid for” [which makes no sense at all] proves that Man will never fly. Fine’s fruit fly chapter is completely pointless. This lawyerly rhetorical technique, criticizing an early experiment in order to snipe at a well-established contemporary theory, was also used by S.J. Gould in The Mismeasure of Man, when he argued that Samuel Morton had skewed his measurements of skulls to fit his preconceptions. Which was untrue – but it wouldn’t have mattered a rat’s ass if Morton had screwed up, because the art has advanced very far since Morton’s time. Today we use MRI and CAT scanners to image skulls to millimetric precision.

Fine takes a stab at showing that there’s isn’t much point [in terms of extra evolutionary fitness] in men getting extra mates. She comes up with an unphysical and absurd example – mentioning how unlikely it would be for 100 one-night stands to generate an extra 100 babies. That’s totally irrelevant: all it shows is that she’s innumerate. Here’s the practical example: suppose some dude has a wife and a girlfriend next door. Suppose he has intercourse 50 times with each of them over a year – both are probably going to have a kid, while with just the wife , he would have had one. 2 > 1. Am I getting too abstract here? By the way, if sexual selection doesn’t really happen, what could explain men’s huge strength advantage? Eating Wheaties?

Fine seems to think that only producing a horde of extra kids could have any evolutionary significance – but she is wrong. One more kid is a big deal, fitness-wise. On average, over most of the human past, people only managed to raise two children to adulthood. In real life there are always other factors to consider, of course. Does he have enough resources to feed one more child? Is his girlfriend married, and will her husband be duped into raising someone else’s kid? Or will her husband get wise and clobber our protagonist?

Fine is inspired here by some work by Dorothy Einon, who attempted to show that a famous case, where Sultan Moulay Ismail (“the Bloodthirsty”) is said to have fathered 888 children, couldn’t possibly have happened. Einon was wrong: careful simulations show that it was possible, although Ismail did show real dedication. Fine manages to misunderstand Einon’s mistakes.

If you make a math model whose results that completely contradict common knowledge – if it predicts that the Saudi royal family does not exist, or that Miles Park Romney didn’t father 30 children – you would be well advised to recheck it. Just sayin’.

Fine goes on to criticize the ‘man-the-promiscuous-horny-hunter/woman-the-choosy-chaste-gatherer. It can’t be the case that men want sex more than women – why, if that were true, prostitution would exist. Ba-dum-bump. Among foragers, are men really the hunters, almost always? Of course they are: men have much greater upper body strength. Spears and arrows don’t launch themselves.

it is possible to argue against a too-simple version of that narrative. For example, in populations of European descent – the ones we’ve looked at – the rate of false paternity is low, around 1-2%, and has been for centuries. It is not the case that many women have children by alphas and trick betas into paying the bills.

Another approach would be looking at brains, trying to identify sex differences (or the lack of them) in brain structure. If men’s and women’s brains were indistinguishable, surely men and women be couldn’t be psychologically different. But that notion is a bit treacherous, since it assumes that we can detect all functionally relevant differences in the brain. We can’t – certainly not in living subjects, but not even in studies after death. How do you detect memories? Can we see the differences in the brains of border collies that make them want to herd sheep? Not yet. Fine discusses some work by Daphna Joel, a behavioral neuroscientist at Tel Aviv University. Joel thinks that there really aren’t differences between male and female brains. Oddly enough, other people, like Larry Cahill, can reliably identify a brain’s sex: no single currently measured feature is definitive (other than presence of a Y-chromosome) , but statistical approaches exist that can make that distinction almost perfectly. Women’s brains are smaller (even after adjusting for body weight), connectivity patterns are different, white/grey matter percentages differ, gene expression patterns in the brain are different, etc., etc. Daphna Joel is a bad source: she sees what she wants to see, and disregards the rest. Psychology seems to have a bad case of that, which is why we’re hearing about the “replication crisis”. Michael Inzslicht, a dealer in stereotype threat and ego depletion [and unicorns] , said ” As I said, I’m in a dark place. I feel like the ground is moving from underneath me and I no longer know what is real and what is not.”

The incidence of mental illness is not the same in the two sexes: dyslexia and autism are much more common in males, depression more common in females. Sex differences in brain structure ( could be differences in gross anatomy or down at the molecular level) must be responsible for these differences in disease incidence.

In talking about the effects of testosterone, Fine mention a kind of cichlid fish where dominance influences gonadal events – causation ( in part) goes from behavior to hormones, instead of hormones to behavior. Interesting. But is there evidence of a similar pattern in humans? No. Are humans so evolutionarily close to fish – in particular, cichlid fish – that any pattern we see in cichlids is an immediate heads-up, something that might be happening in humans? Christ no. Then what’s the God-damn point? If we’re talking logic and inference, there is none: Fine seems to think that random unconnected facts are just fine for confusing her audience, and of course she’s right about that. Or, more charitably and probably more accurately, they’re good at confusing her. Makes me miss ye olde-fashioned steel-making, pistol-packing, Cheka-loving Commies: one of them could write an entire book explaining how humans are really vernalized naked mole rats while still sounding intelligent.

If, in this book, Fine had at some point conducted a sharp analysis and found the hidden causal pattern in a web of data, or had a sound mathematical model that answered the key question, or even casually tossed off a few accurate thoughts about the central limit theorem or Simpson’s paradox, I’d have to think that she was a bad person – dishonest. I see no sign of that.

At the end of her book, Fine says that we’re all for sex equality. I can think of at least a billion exceptions to that statement – but let me say this: I’m for what works. Listening to Cordelia Fine is not going to make things work better.
Stop the presses. Chateau Heartiste is commenting on the same Greg Cochran post here [link]. I've extracted the quote in the last quibcag from his commentary. Now, the illustration on that quibcag may confuse those of you who are not familiar with Ranma ½ (らんま½). Pictured is Ranma-chan, who is the female version of Ranma. Ranma fell into a cursed Chinese spring once, and since then turns into a girl whenever he's splashed with cold water. He turns back into a boy with the application of hot water. Now, in the picture, Ranma-chan is making a martial arts move, and she is a total master of martial arts. However, Ranma her/himself acknowledges that boy Ranma is a better martial artist than girl Ranma. It's just that bundle of physiological differences. This demonstrates that males are intrinsically better at combat than females, even if the female is the same person, transformed magically from a male. By the way, this is one of my two favorite animes — Ranma ½ (らんま½) and Detective Conan (Meitantei Conan  名探偵コナ). Conan, AKA Meitantei Conan (名探偵コナン). I recommend them both to you.
Quibcag: Illustration by diami-mi. The second one is an old Johnny Quest still. Number three is Pepe and I don't know where the girl came from. Fourth is illustrated by Mori Ran of Detective Conan (Meitantei Conan  名探偵コナ). Conan, AKA Meitantei Conan (名探偵コナン). Fifth is illustrated, mostly, by our own Baloo. The sixth I found on the net, and the seventh is illustrated by Princess Mononoke (Japaneseもののけ姫 HepburnMononoke-hime, "Spirit/Monster Princess").  The eighth is Sensei, from Denkigai no Hon'ya-san (デンキ街の本屋さん?, lit. "The Electric Town's Bookstore"). And the final one is illustrated by Ranma of Ranma ½ (らんま½). More about that in the body of the post.


  1. I think God had the angels do the engineering for Man and Woman.
    Man is the powerful but faulty prototype.
    Woman is the thrifted production model (but the milk thing works).

  2. It can’t be the case that men want sex more than women – why, if that were true, prostitution would exist.

    Technically speaking, prostitution is not the evidence that men want sex more than women - that prostitution is so female-dominated is the evidence.

  3. I have long wondered when the left will turn and denounce Darwin? They have long been proclaiming themselves Darwinists while rejecting almost everything Darwin said about species and evolution. Their one reason for still proclaiming Darwin is that it’s a useful club to attack Christians who believe in creationism.

    On the other hand Darwin goes against the lefts idea that all humans are the same except for white males who are more evil. And he is even a White Male Heterosexual, which is the most evil type of White Male.

    So look out for a time coming soon when Darwin will be denounced, his publications classified as hate crimes, and his honors withdrawn

  4. Women do science for the same reason they do everything else, to feel good. Facts don't enter into it. Fat girls say looks don't matter. Smart girls say brains are better than beauty. Old women say thet age is just a number. What would you call that? I really don't care, but its not SCIENCE.
