A theory of male and female Sociopathy pt 3

Note: this is just a theory, developed in reaction to recent conversations. 

From Twitter user FinchesofDarwin comes an interesting tale, about a polygynously-married woman in Guiana: 

Manwaiko had two wives, and each of these had a family of young children. … Between the two wives and their respective children little kindness seemed to exist. One evening, while the party were squatting on the ground, eating their supper… one of the wives, who with her children had been employed in cutting firewood, discovered, on her return, that the supper for herself and her family was not to be found, having been carried off by some animal through neglect or connivance of her rival. It could hardly be expected that she would sit down quietly without the evening meal for herself and her children… and she accordingly applied to Manwaiko for a share of his allowance, which was ample. He treated her request with contempt… She then commenced a furious torrent of abuse, during which he finished his meal with great composure, until, being irritated at his indifference, she at last told him that he was no “capitan,” no father, and no man. …  

Such stormy ebullitions of temper are rare in the Indian families, though, where polygamy is practiced, continual variance and ill-feeling are found. 

From The Indian Tribes of Guiana, their Condition and Habits, by Reverend Brett, 1868

As we were discussing Friday, one form of female sociopathy (at least relevant to this conversation) likely involves manipulating or coercing others into providing resources for her children. On Monday we discussed mental illness and its effects on fertility (generally it lowers fertility in men, but depression has little to no effect on women, neuroticism may enhance fertility, and sometimes the sisters of people with mental illnesses have slightly increased fertility, suggesting that low levels of certain traits may be beneficial.) 

Here is where I get 100% speculative, and to be frank, I don’t like saying negative things about women (since I am one,) but if men can be sociopaths, then women can, too–and conversely, the majority of men are not sociopaths, and neither are the majority of women. 

In the quoted passage, we see two common tropes: First, the evil stepmother, in the form of the wife who let wild animals make off with half of the family’s food. Second, the crazy bitch, who goes on a tirade questioning her husband’s manliness because he has failed to provide food for her children. 

In this case, only the first woman is truly sociopathic (she has harmed the other woman and her children,) but we can see how the second’s behavior could easily spill over into unreasonable demands. 

Female sociopathy–manipulating men out of their money–only works as an evolutionary strategy in an environment where men themselves vary in their trustworthiness and cannot be easily predicted. If the men in a society can be counted upon to always provide for their offspring, women have no need to try to manipulate them into doing so; if men in a society flat out refuse to do so, then there is no point to trying. Only in a situation where you can affect the amount of resources you get out of a man will there be any point to doing so.

Given the environmental constraints, sociopathic female behavior is likely to increase in reaction to an increase in sociopathic male behavior–that is, when women fear abandonment or an inability to care for their children.

This manipulation has two targets–first, the father of the child, whom the woman wishes to prevent from wandering off and having children with other women, or baring that, from giving them any resources. Second, should this fail, or the male be too violent for women and children to be near, the woman targets a new male to convince him to care for her, her children, and possibly beat the resources out of the old male. 

Since children actually do need to eat, and getting enough resources can be tough, society is generally fine with women doing what they need to provide for their families (unlike men doing whatever they need to maximize reproduction, which usually ends with the police informing you that no, you cannot go “Genghis Khan” on Manhattan.) 

But at times women really do go overboard, earning the title of “crazy ex.” Here’s part of one woman’s helpful list of why she went crazy:

1. He told me he loved me, then he left me. … I wasn’t going to make it easy for him to leave me. I promised myself I’d fight for my relationship because I loved him and he said he loved me. …
3. If you didn’t know, one of the quickest ways to drive a woman insane is to ignore her. … This was the most severe phase of crazy for me. I was infuriated that not only was I losing my relationship and wasn’t given a reason why, but I was being blatantly ignored by him too! …
4. He told me not to worry about his “friend,” and now he’s dating her.

Back before the invention of birth control, a woman who got dumped like this was most likely pregnant, if not already caring for several children. Abandonment was a big deal, and she had every reason not to just let her partner wander off and start impregnating new chicks. 

In our modern world, he made it clear that he didn’t want to be in a relationship anymore and left. 


And a similar story on Quora

After my ex boyfriend broke up with me I went crazy… After he dumped me for the third time I felt used and devastated. I wanted an explanation and answers. He was a jerk to me. A cruel son of a bitch. I kept begging, calling, and begging. I never got a reply back. This went on for over 3 months. …

Third. Time. 

This isn’t the only kind of “crazy” I’ve seen around, though. 

An acquaintance recently recounted a story about an ex who actually ended up in the mental hospital for suicidal ideation. She listed him as her contact, something he was not exactly keen on, having already told her the relationship was over. 

Then there is the phenomenon of people actually claiming to be crazy, often with rather serious disorders that you would not normally think they would want to revealing to others. For example, I have seen several young women claim recently to have Multiple Personality Disorder–a condition that is not in the DSM and so you can no longer get diagnosed with it. Though you can get diagnosed with Disassociative Identity Disorder, this disorder is rare and quite controversial, and I would expect anyone with a real diagnosis to use the real name, just as few schizophrenics claim to have been diagnosed with dementia praecox. 

MPD is less of a real disorder and more of a fad spread by movies, TV, and unscrupulous shrinks, though many people who claim to have it are quite genuinely suffering. 

(I should emphasize that in most of these cases, the person in question is genuinely suffering.) 

Most of these cases–MPD, PTSD, etc–are supposedly triggered by traumatic experiences, such as childhood abuse or spousal abuse. (Oddly, being starved half to death in a POW camp doesn’t seem to trigger MPD.) And yet, despite the severity of these conditions, people I encounter seem to respond positively to these claims of mental illness–if anything, a claim of mental illness seems to get people more support. 

So I suggest a potential mechanism:

First, everyone of course has a pre-set range of responses/behaviors they can reasonably call up, but these ranges vary from person to person. For example, I will run faster if my kids are in danger than if I’m late for an appointment, but you may be faster than me even when you’re just jogging.

Second, an unstable, violent, or neglectful environmental triggers neuroticism, which in turn triggers mental instability. 

Third, mental instability attracts helpers, who try to “rescue” the woman from bad circumstances. 

Fourth, sometimes this goes completely overboard into trying to destroy an ex, convincing a new partner to harm the ex, spreading untrue rumors about the ex, etc. Alternatively, it goes overboard in the woman become unable to cope with life and needing psychiatric treatment/medication.

Since unstable environments trigger mental instability in the first place, sociopathic men are probably most likely to encounter sociopathic women, which makes the descriptions of female sociopathy automatically sound very questionable:

“My crazy ex told all of our friends I gave her gonorrhea!”

“Yeah, but that was after you stole $5,000 from her and broke two of her ribs.” 

This makes it difficult to collect objective information on the matter, and is why this post is very, very speculative. 


A theory of male and female Sociopathy, pt 2

Note: this is just a theory, developed in reaction to recent conversations. 

As we were discussing Friday, one form of female sociopathy (at least relevant to this conversation) likely involves manipulating or coercing others into providing resources for her children.

There are a couple of obvious tropes:

  1. The evil stepmother, who shunts resources away from a man’s first child, toward his later children. 
  2. The cuckoldress, who tricks or convinces a man to care for another man’s children (this is not always seen as evil, since the male drive to provide for children is triggered at least partly by their proximity, since men cannot give birth, and thus men feel genuine affection for children who happen to be around them,)
  3. The crazy ex, who sues a man for all he is worth, doing her best to prevent him from being able to provide for any future children. 

How crazy are women? 


22%–slightly more than 1 in 5–women have been diagnosed with a mental illness, at least according to all of the data I’ve seen. Since mental illness peaks during the childbearing ages and falls off quickly after menopause, we can also assume that this rate is closer to 1 in 4 during these years. 

(The dramatic problems our Native American communities are facing is a separate matter, deserving of its own post.)

The odd thing about this data is that mental illness rates are higher for women than men, despite the fact that mental retardation and mental disability rates are higher for men than women. Men are more likely than women to have serious conditions like non-verbal autism and schizophrenia, more likely to be homeless or commit suicide. When things go terribly wrong, the sufferers are disproportionately male (an unfortunate side effect of the Y chromosome causing greater male variability than female variability on a variety of traits.) 

So why on earth do more women than men suffer from mental illness? 

Perhaps some forms of mental illness confer some unexpected benefits on women. 

Many (perhaps most) “mental illnesses” correlate with a single personality trait–neuroticism

“Previously we thought that mental illnesses such as depression, schizophrenia, bipolar disorder, and substance abuse, were completely separate diseases,” Ystrøm says.

But research has now shown that these illnesses are often linked. If you suffer from one mental illness, you are more likely to develop another. And if someone in your immediate family has a psychiatric illness, your risk increases not only for this disorder, but for all other disorders.

These findings have led researchers to suspect that there could be a common underlying factor that increases an idividual’s risk of mental illness, overall. … 

Ystrøm and colleagues have used new statistical methods to look for patterns in personality, mental disorders, genes, and environmental factors, among the twins in the Twin Register. 

And the answer to the question the researchers asked is: yes, neuroticism seems to be the personality trait that best describes the risk of all mental disorders. …

“This one trait doesn’t explain everything. Anyone can develop a mental illness…”

And in women, neuroticism correlates with… more surviving offspring (in at least one study)

Taking an evolutionary approach, we use data from a contemporary polygynous high-fertility human population living in rural Senegal to investigate whether personality dimensions are associated with key life-history traits in humans, i.e., quantity and quality of offspring. We show that personality dimensions predict reproductive success differently in men and women in such societies and, in women, are associated with a trade-off between offspring quantity and quality. In women, neuroticism positively predicts the number of children, both between and within polygynous families. Furthermore, within the low social class, offspring quality (i.e., child nutritional status) decreases with a woman’s neuroticism, indicating a reproductive trade-off between offspring quantity and quality. 

What is neuroticism, in the Big 5 Personality Traits* sense? 

*Note: I am not endorsing or denying all five traits one way or another.

It’s worrying. Mothers who worry more about their offspring have more offspring–though it’s quite easy to imagine that the causality points in the opposite direction as the study’s authors conclude–poor women with lots of skinny babies have more reason to worry about their children than women with a few fat babies. 

When are women most likely to experience mental illness?

Immediately after the birth of a child. It’s called post-partum depression, and it can be very bad–one woman in my moms’ group ended up in the mental hospital after developing post-partum psychosis. Andrea Yates famously drowned her five children during a bout of post-partum depression/psychosis.

Why on earth would women develop a debilitating mental illness at the most vulnerable time in their offspring’s life? Wouldn’t natural selection select rather quickly against anything that makes women worse at taking care of their offspring? 

Let’s turn to everyone’s favorite genetic disease, sickle cell anemia. SCA is famous for being a relatively simple genetic mutation of the sort where if you have one copy of the sickle cell gene, you are less likely to get malaria, and if you have two copies, you tend to die. In areas where malaria is common, the cost of having a quarter of your children die from SCA is lower than the cost of loosing them to malaria. 

Personality traits, including neuroticism, generally exist on a continuum. People may become more neurotic when life warrants it, and less neurotic when they don’t need to worry. A mother with a new baby is in a very vulnerable state–she has just lost a good deal of blood, may not be able to walk, and has an infant to care for every other hour, day and night. It is not a normal state by any measure. It is a time when being extra attentive and extra aware of threats and predators is in a woman’s interest.

It is also a time when women are most in need of help from their mates, relatives, or other friends. Increased neuroticism may also prompt others to attend more closely to the new mother, helping her out. . Increased neuroticism may be so helpful during this time period that a few women getting way too much neuroticism and becoming extremely depressed or even killing their children is a cost outweighed by the increased survival of babies whose mothers had moderate levels of neuroticism. 

Let us note that nature doesn’t care about your feelings. Male praying mantises who allow themselves be eaten by their mates have more offspring than the ones who don’t, but that doesn’t mean male praying mantises enjoy getting eaten. Children who die of sickle

cell anemia don’t much appreciate that their siblings were protected from malaria, either.

An increase in neuroticism immediately after the birth of a baby may prompt a mother to take better care of it, but that doesn’t mean she enjoys the neuroticism. Neither does it mean that post-partum depression is healthy, any more than sickle cell anemia is healthy just because it’s a side effect of a trait that helps people avoid malaria. 

But wait, I have more studies!

Reproductive Fitness and Genetic Risk of Psychiatric Disorders in the General Population

The persistence of common, heritable psychiatric disorders that reduce reproductive fitness is an evolutionary paradox. Here, we investigate the selection pressures on sequence variants that predispose to schizophrenia, autism, bipolar disorder, major depression and attention deficit hyperactivity disorder (ADHD) using genomic data from 150,656 Icelanders, excluding those diagnosed with these psychiatric diseases. … Higher polygenic risk of autism is associated with fewer children and older age at first child whereas higher polygenic risk of ADHD is associated with having more children. We find no evidence for a selective advantage of a high polygenic risk of schizophrenia or bipolar disorder. Rare copy-number variants conferring moderate to high risk of psychiatric illness are associated with having fewer children and are under stronger negative selection pressure than common sequence variants. …

In summary, our results show that common sequence variants conferring risk of autism and ADHD are currently under weak selection in the general population of Iceland. However, rare CNVs that also impact cognition are under stronger selection pressure, consistent with mutation-selection balance. The hypothesis that a selective advantage accounts for the prevalence of sequence variants conferring risk of schizophrenia and bipolar disorder is unproven, but rather this empirical evidence suggests that common sequence variants largely escape selection as their individual effect sizes are weak.

Unfortunately, this study mostly looks at the data in aggregate, instead of breaking it down by males and females. (And I don’t know why they would bother excluding people who actually have the conditions they are trying to study, but perhaps it doesn’t make much difference.) 

Thankfully, they did break down the data by male/female in the tables–Table 1 and Table 2. These tables are confusing, but the takeaway is that mental illness has a bigger effect on male fertility than female fertility. 

Also: Fecundity of Patients with Schizophrenia, Autism, Bipolar Disorder, Depression, Anorexia Nervosa, or Substance Abuse vs. their Unffected Siblings

Results Except for women with depression, affected patients had significantly fewer children (FR range for those with psychiatric disorder, 0.23-0.93; P < 10−10). This reduction was consistently greater among men than women, suggesting that male fitness was particularly sensitive. Although sisters of patients with schizophrenia and bipolar disorder had increased fecundity (FR range, 1.02-1.03; P < .01), this was too small on its own to counterbalance the reduced fitness of affected patients. Brothers of patients with schizophrenia and autism showed reduced fecundity (FR range, 0.94-0.97; P < .001). Siblings of patients with depression and substance abuse had significantly increased fecundity (FR range, 1.01-1.05; P < 10−10). In the case of depression, this more than compensated for the lower fecundity of affected individuals.

Conclusions Our results suggest that strong selection exists against schizophrenia, autism, and anorexia nervosa and that these variants may be maintained by new mutations or an as-yet unknown mechanism. Bipolar disorder did not seem to be under strong negative selection. Vulnerability to depression, and perhaps substance abuse, may be preserved by balancing selection, suggesting the involvement of common genetic variants in ways that depend on other genes and on environment.

Now, this study gets interesting in its graphs: 

From Fecundity of Patients with Schizophrenia, Autism, Bipolar Disorder, Depression, Anorexia Nervosa, or Substance Abuse vs their Unaffected Siblings

In every case, mental illness has a bigger effect on male fertility than female–and in the case of depression, it has no effect on female fertility. 

But wait: 

Same source.

This graph is confusingly labeled, but it is breaking down the correlation on the brothers and sisters of people with mental disorders. So the first dot represents the brothers of people with schizophrenia; the second dot represents the sisters of people with schizophrenia. 

None of these effects are huge, and some of them changed when “comorbidities were included in the analysis,” though it’s not clear exactly what that means–the word comorbidity in this context refers to people with more than one diagnosis. 

For the objectives of this study, we first analyzed each disorder separately without accounting for comorbidities. A secondary analysis was then performed that corrected for comorbidities by analyzing all disorders simultaneously.

So when you analyze all of the disorders together, sisters of schizophrenics had no increased fertility, and neither did the siblings of people with bipolar. Depressed men had average fertility, while depressed women actually had slightly above average fertility. The results for anorexia, substance abuse, and autism didn’t change. 

And from Spain: Seven Dimensions of Personality Pathology are Under Sexual Selection in Modern Spain

Personality variation is increasingly thought to have an adaptive function. This is less clear for personality disorders (PDs)—extreme variants of personality that cause harm in most aspects of life. However, the possibility that PDs may be maintained in the population because of their advantages for fitness has been not convincingly tested. In a sample of 959 outpatients, we examined whether, and how, sexual selection acts on the seven main dimensions of personality pathology, taking into account mating success, reproductive success, and the mediating role of status. We find that, to varying extents, all personality dimensions are under sexual selection. Far from being predominantly purifying, selective forces push traits in diverging, often pathological, directions. These pressures differ moderately between the sexes. Sexual selection largely acts in males through the acquisition of wealth, and through the duration (rather than the number) of mates. This gives a reproductive advantage to males high in persistence–compulsivity. Conversely, because of the decoupling between the number of mates and offspring, the promiscuous strategy of psychopaths is not so successful. Negative emotionality, the most clinically detrimental trait, is slightly deleterious in males but is positively selected in females, which can help to preserve variation. 

It’s interesting that the invention of birth control may have inadvertently selected against promiscuous psychopaths–rather similar to the theory that abortion is responsible for the decrease in crime since the early 90s. 

“Negative emotionality” is likely equivalent to “neuroticism.”

There are two obvious reasons why mental illness might have more of an effect on males than females–one is that mental illness might simply be mores severe for males than females, on average. The second is that mental illness interferes more with holding down a job than with being a housewife, so women with mental illnesses have more options than men. 

Less obvious, though, is that some of these traits might actually be beneficial–in small quantities–for women.

That’s enough for now; let’s continue this discussion on Friday. (Wednesday is book club.) 

A theory of male and female Sociopathy pt 1

Note: this is just a theory, developed in reaction to recent conversations. 

Let us assume, first of all, that men and women have different optimal reproductive strategies, based on their different anatomy. In case you have not experienced birth yourself, it’s a difference of calories, time, and potential death. 

In the ancestral environment (before child support laws, abortion, birth control, or infant formula):

For men, the absolute minimal paternal investment in a child–immediate abandonment–involves a few minutes of effort and spoonful of semen. There are few dangers involved, except for the possibility of other males competing for the same female. A hypothetical man could, with very little strain or extra physical effort, father thousands of children–gay men regularly go through the physical motions of doing just that, and hardly seem exhausted by the effort.

For women, the absolute minimal parental investment is nine months of gestation followed by childbirth. This is calorically expensive, interferes with the mother’s ability to take care of her other children, and could kill her. A woman who tried to maximize her pregnancies from menarchy to menopause might produce 25 children. 

If a man abandons his children, there is a decent chance they will still survive, because they can be nursed by their mother; if a woman abandons her child, it is likely to die, because its father cannot lactate and so cannot feed it. 

In sum, for men, random procreative acts (ie, sex) are extremely low-cost and still have the potential to produce offspring. For women, random procreative acts are extremely costly. So men have an incentive to spread their sperm around and women have an incentive to be picky about when and with whom they reproduce.  

This is well known to, well, everyone. 

Now, obviously most men do not abandon their children (nor do most women.) It isn’t in their interest to do so. A man’s children are more likely to survive and do well in life if he invests in them. (In a few societies where paternity is really uncertain, men invest resources in their sisters’ children, who are at least related to them, rather than opting out altogether.) As far as I know, some amount of male input into their children or their sisters’ children is a human universal–the only variation is in how much. 

Men want to invest in their children because this helps their children succeed, but a few un-tended bastards here and there are not a major problem. Some of them might even survive. 

By contrast, women really don’t want to get saddled with bastards. 

We may define sociopathy, informally, as attempting to achieve evolutionary ends by means that harm others in society, eg, stealing. In this case, rape and child abandonment are sociopathic ways of increasing men’s reproductive success at the expense of other people. (Note that sociopathy doesn’t have a formal definition and I am using it here as a tool, not a real diagnosis. If someone has a better term, I’m happy to use it.)

This is, again, quite obvious–everyone knows that men are much more likely than women to be imprisoned for violent acts, rape included. Men are also more likely than women to try to skip out on their child support payments. 

Note that this “sociopathy” is not necessarily a mental illness, (a true illness ought to make a dent on one’s evolutionary success.) Genghis Khan raped a lot of women, and it turned out great for his genes. It is simply a reproductive strategy that harms other people. 

So what does female sociopathy look like? 

It can’t look like male sociopathy, because child abandonment decreases a woman’s fertility. For a woman, violence and abandonment would be signs of true mental defects. Rather, we want to look at ways women improve their chances of reproductive success at the expense of others. 

In other words, female sociopathy involves manipulating or coercing others into providing resources for her children. 

But it’s getting late; let’s continue with part 2 on Monday. (Wednesday is book club.)

Why is community dead: In which I blame colleges.


By any objective analysis, life in modern America is pretty darn good. You probably didn’t die in childbirth and neither did half of your children. You haven’t died of smallpox or polio. You probably haven’t lived through a famine or war. Cookies and meat are cheap, houses are big, most of us do rather little physical labor, and we can carry the collected works of Shakespeare, Tolstoy, and Wikipedians in our pockets. We have novacaine for tooth surgery. If you avoid drugs and don’t eat too much, there’s a very good chance you’ll survive into your eighties.

Yet anxiety is skyrocketing.  Something about modern life doesn’t seem to agree with people.

In the past, people grew up in small towns or rural areas near small towns, knew most of the people in their neighborhoods, went to school, got jobs, and got married. They moved if they needed more land or saw opportunities in the gold fields, but most stayed put.
We know this because we can read about it in historical books.

One of the results was strong continuity of people in a particular place, and strong continuity of people allowed the development of those “civic associations” people are always going on about. Kids joined clubs at school, clubs at church, then transitioned into adult-aged clubs when they graduated. At every age, there were clubs, and clubs organized and ran events for the community.

Of course club membership was mediated by physical location–if you live in a town you will be in more clubs than if you live in the country and have to drive an hour to get there–but in general, life revolved around clubs (and church, which we can generously call another kind of club, with its own sub clubs.)

In such an environment, it is easy to see how someone could meet their sweetheart at 16, become a functioning member of society at 18, get a job, put a down payment on a house, get married by 20 or 22 and start having children.

Today, people go to college.

Forget your highschool sweetheart: you’re never going to see her again.

After college, people typically move again, because the job they’ve spent 4 years training for often isn’t in the same city as their college.

So forget all of your college friends: chances are you’ll never see any of them again, either.

Now you’re living in a strange city, full of strangers. You know no one. You are part of no clubs. No civic organizations. You feel no connection to anyone.

county-economic-status_fy2015_map“Isn’t diversity great?” someone crows over kebabs, and you think “Hey, at least those Muslims over there have each other to talk to.” Soon you find yourself envying the Hispanics. They have a community. You have a bar.

People make do. They socialize after work. They reconnect with old friends on Facebook and discover that their old friends are smug and annoying because Facebook is a filter that turns people smug and annoying.

But you can’t repair all of the broken connections.
Meanwhile, all of those small, rural towns have lost their young adults. Many of them have no realistic future for young people who stay; everyone who can leave, does. All that’s left behind are children, old people, and the few folks who didn’t quite make it into college.

The cities bloat with people who feel no connection to each other and small towns wither and die.

As the Guardian Reports: Why are so many people dying of opiate overdoses?:

Never mind the ‘war on drugs’ or laying all blame with pharmas, this epidemic exists because millions live in a world without hope, certainty and structure…

The number one killer of Americans under the age of 50 isn’t cancer, or suicide, or road traffic accidents. It’s drug overdoses. They have quadrupled since 1999. More than 52,000 Americans died from drug overdoses last year. Even in the UK, where illegal drug use is on the decline, overdose deaths are peaking, having grown by 10% from 2015 to 2016 alone. …

Opioids, whatever their source, bond with receptors all over our bodies. Opioid receptors evolved to protect us from panic, anxiety and pain – a considerate move by the oft-callous forces of evolution. …

The overdose epidemic compels us to face one of the darkest corners of modern human experience head on, to stop wasting time blaming the players and start looking directly at the source of the problem. What does it feel like to be a youngish human growing up in the early 21st century? Why are we so stressed out that our internal supply of opioids isn’t enough? …

You get opioids from your own brain stem when you get a hug. Mother’s milk is rich with opioids, which says a lot about the chemical foundation of mother-child attachment. When rats get an extra dose of opioids, they increase their play with each other, even tickle each other. And when rodents are allowed to socialise freely (rather than remain in isolated steel cages) they voluntarily avoid the opiate-laden bottle hanging from the bars of their cage. They’ve already got enough. …

So what does it say about our lifestyle if our natural supply isn’t sufficient and so we risk our lives to get more? It says we are stressed, isolated and untrusting.

(Note: college itself is enjoyable and teaches people valuable skills. This thread is not opposed to “learning things,” just to an economic system that separates people from their loved ones.)

Mysticism and Greater Male Variability

ctqda7fweae8tnbBuzzwords like “the male gaze” “objectification” “stereotype threat” “structural oppression” “white privilege” etc. are all really just re-hashings of the Evil Eye. We’ve shed the formal structure of religion but not the impulse for mystical thinking.

Today while debating with a friend about whether men or women have it better, it became plain that we were approaching the question from very different perspectives. He looked at men’s higher incomes and over-representation among CEOs and government officials and saw what I’ll call the mystical explanation: male oppression of women. I looked at the same data plus male over-representation among the homeless, mentally ill, suicides, and murder victims, and advocated the scientific explanation: greater male variability. 

What do I mean by mystical?

In primitive tribes, an accusation of witchcraft can quickly get you killed. What might inspire an accusation of witchcraft? A sick cow, a sudden death, a snake in a spot where it wasn’t yesterday, a drought, a flood, a twisted ankle–pretty much anything unexpected or unfortunate.

People understand cause and effect. Things happen because other things make them happen. But without a good scientific understanding of the world, the true causes of many events are unfindable, so people turn to mystical explanations. Why does it rain? Because a goddess is weeping. Why do droughts happen? Because someone forgot to make a sacrifice and angered the gods. Why do people get sick and die? Because other people cursed them.

If you’ve never encountered animist or mystical thought before, I recommend starting with some of my previous posts on the subject, which are thoroughly-researched and include lots of quotes from first-hand sources: Animism 1, 2, and 3; Aboriginal Witchcraft, more Australia 1, 2, and 3; mysticism and voodoo 1, 2, and 3. In this post I will be drawing on summaries of these and similar works.

A curse need not be deliberate. Simply being mad at someone or bearing them ill-will might be enough trigger the Evil Eye, curse them, and be forced by angry villagers to undo the curse–however the witchdoctor determines the curse must be undone. (This can be quite expensive.)

In animist thinking, things do not just happen. Things happen for reasons–usually malicious reasons.

In The Life and Adventure of William Buckley, 32 Years a Wanderer amongst the Aborigines, Buckley recounts: “They have an odd idea of death, for they do not suppose that any one dies from natural causes, but from human agencies: such as those to which I have alluded in previous pages of this narrative.”

The death of a companion via snakebite (probably a  common occurrence among people who walk barefoot in Australia) triggered a brutal “revenge” killing once it was determined who had cast the curse that motivated the snake:

“The cause of this sudden unprovoked cruelty was not, as usual, about the women, but because the man who had been killed by the bite of the snake belonged to the hostile tribe, and they believed my supposed brother-in-law carried about with him something that had occasioned his death. They have all sorts of fancies of this kind, and it is frequently the case, that they take a man’s kidneys out after death, tie them up in something, and carry them round the neck, as a sort of protection and valuable charm, for either good or evil.”

Buckley’s adoptive Aboriginal family, his sister and brother-in-law, who had been helping him since the tribe saved his life years ago, was killed in this incident.

“I should have been most brutally unfeeling, had I not suffered the deepest mental anguish from the loss of these poor people, who had all along been so kind and good to me. I am not ashamed to say, that for several hours my tears flowed in torrents, and, that for a long time I wept unceasingly. To them, as I have said before, I was as a living dead brother, whose presence and safety was their sole anxiety. Nothing could exceed the kindness these poor natives had shown me, and now they were dead, murdered by the band of savages I saw around me, apparently thirsting for more blood. Of all my sufferings in the wilderness, there was nothing equal to the agony I now endured.” …

“I returned to the scene of the brutal massacre; and finding the ashes and bones of my late friends, I scraped them up together, and covered them over with turf, burying them in the best manner I could, that being the only return I could make for their many kindnesses. I did so in great grief at the recollection of what they had done for me through so many years, and in all my dangers and troubles. ”

An account of Florence Young’s missionary work in the Solomon Islands (which are near Australia) recounts an identical justification for the cycle of violence on the Solomon Islands (which was quite threatening to Florence herself.) Every time someone died of any natural cause, their family went to the local witch doctor, who then used magic to determine who had used evil magic to kill the dead guy, and then the family would go and kill whomever the witch doctor indicated.

The advent of Christianity therefore caused a power struggle between the missionaries and the witch doctors, who were accustomed to being able to extort everyone and trick their followers into killing anyone who pissed them off. (See also Isaac Bacirongo’s account of the witch doctor who extorted his pre-pubescent sister as payment for a spell intended to kill Isaac’s wife–note: Isaac was not the one buying this spell; he likes his wife.)

So why do women make less money than men? Why are they underrepresented among CEOs and Governors and mathematicians? Something about the patriarchy and stereotype threat; something about men being evil.

Frankly, it sounds like men have the Evil Eye. A man thinks “Women are worse at math” and women suddenly become worse at math.

To be fair, my friend had only half the data, and when you have only half the data, the situation for men looks a lot better than the situation for women. But men aren’t only over-represented at the high ends of achievement–they’re also over-represented at the bottom. If patriarchy and stereotypes keep women from getting PhDs in math, why are little boys over-represented in special ed classes? Why are they more likely to be homeless, schizophrenic, commit suicide, or be murdered? Neither patriarchy nor male privilege can explain such phenomena.

Biology supplies us with a totally different explanation: greater male variability.

To review genetics, you have 23 pairs of chromosomes. Most of them are roughly X-shaped, except for the famous Y chromosome.

You have two chromosomes because you received one from each of your parents. Much of what the chromosomes do is redundant–for example, if you have blue eyes, then you received a gene for blue eyes from one parent and one from your other parent. One blue eye gene would be enough to give you blue eyes, but you have two.

Eye color isn’t terribly important, but things like how your immune system responds to threats or how your blood clots are. A rare mutation might make you significantly better or worse at these things, but the fact that you have two (or more) genes controlling each trait means that each very rare mutation tends to be paired with a more common version–lessening its effect.

There is, however, one big exception: the XY pair. Men don’t have a pair of Xs or a pair of Ys; they have one of each. If something is wrong on the X, the Y may have nothing to fix it, and vice versa.

The upshot is that if a man happens to get a gene that makes him extra tall, smart, conscientious, creative, charismatic, etc. somewhere on his X or Y chromosomes, he may not have a corresponding gene on the other chromosome to moderate its effects–and if he has a gene that makes him extra short, dumb, impulsive, dull, or anti-social, he is still unlikely to have a corresponding gene to dull the effect.

ASVAB scores: women in pink, men in blue.

Height is an uncontroversial example. Yes, the average man is taller than the average woman, but the spread of male heights is wider than the spread of female heights. More women are clustered around the average female height, while more men are both taller than the average man and shorter than the average man.

The graph to the right shows test scores from the Armed Services Vocational Aptitude Battery, but it shows the same basic idea: different means with women clustered more closely around average than men.

Whether the greater male variability hypothesis is true or not, it is an explanation that assumes no malice on anyone’s part. No one is maliciously forcing little boys into special ed, nor grown men into homelessness and suicide. The architecture of the XY and XX chromosome pairs is simply part of how humans are constructed.

But notice that you are much more likely to hear the theory that uses mysticism to blame people than the theory that doesn’t. One is tempted to think that some people are just inclined to assume that others are malicious–while ignoring other, more mundane explanations.




Survey: What are your hobbies?

Dividualist has/inspires an interesting question: What non-STEM related hobbies do female nerds have?

Let’s expand this question to everyone who reads this blog: What are your hobbies? Are they mostly STEM-related or non-STEM? (And do you consider yourself a nerd?)

For example, hobbies like “building lasers” or “writing a blog on HBD” count as STEM-related; playing WoW or gardening is non-STEM.

(Then discuss whether this distinction between STEM and non-STEM hobbies is valid.)


For myself: There’s an obvious complication that humans are social creatures and I do a lot of things because other people around me are doing them. EG, I play and enjoy some videogames with my family, but if I lived alone, I wouldn’t have bought a TV, much less a game system.

Similarly, there are things I would like to do if I had more time and money–billionaires can afford more hobbies than we mere plebes. These can be listed as “interests.”

Obviously my chief “hobbies” are writing this blog (which requires a fair amount of reading) and homeschooling my children. I won’t duplicate the blog by listing everything it covers.

I also enjoy writing fiction and reading about topics not covered in this blog, like physics. (Layman level reading.)

Navigation: I am strongly aware of the shape of the local geography and spatial relationship of the sun, shadows, curve of the Earth, progress of seasons, animal migrations, the way prevailing winds shape the local trees, etc. The slanting rays of the afternoon sun have a deep emotional effect.

I like plants and would enjoy having a small farm with more plants, bees, and some chickens. I am fond of afternoons in the woods and foraging for wild edibles.

I enjoy making things, like arts and crafts. I’ve made a number of toys for the kids, built them a small wooden “play house,” and recently finished sewing a dress. If I had money and time, I would invest in woodworking tools and a 3D printer.

I struggle to delineate, exactly, whether these are STEM hobbies or not; “STEM” itself is not a word I like, though I employ it because it is short and utile.

Things I have little to no interest in: sports, cars, travel, sightseeing, holding still (“vacation,”) makeup, celebrities, celebrity gossip, most TV or movies, cupcakes, drinking, bars, hair salons, modern fashion, handbags, and most striver bullshit. These are my misery zone.


What about you?

Vacation Posting pt. 2: Brain Modules, Fertility, and Conspiracy

Sorry, I’ve been on vacation (and no, I do not like vacations.) This has interfered with my normal writing schedule, (it is now past 4 am) but here are the notes I managed to jot down in the car:

2. Brain Modules

This is relevant to my previous post on “The Modular Mind,” in which I proposed that people use a kind of compartmentalized or “modular” thinking to break down the complexity of life into manageable chunks. People can hold two beliefs at once that they think are “logical” but contradict each other because each belief is sort of “lodged in” a different module.

For example, Module 1 likes to think about Pensions. Mod 1 knows that pensions are paid for via current workers’ salaries, so we have to have enough future workers to fund future pension obligations.

Module 2 likes to think about the Environment. Mod 2 knows that we only have so many resources and that a growing population will quickly exhaust them, so we must reduce birthrates to save the environment.

Mod 1 then looks around and panics because, Oh no, there aren’t enough young people around to fund the pensions!

Mod 1 doesn’t bother to check in with Mod 2 about why there aren’t enough babies around. It just has some vague idea that people don’t want to make babies for some reason, so it goes and finds some people who do make babies and propose that we let more of them into the country.

Mod 1: Problem solved!

Mod 2: Oh no, look what all of those new people just did to our carbon footprint! We will have to reduce and conserve even more!

Modular thinking lets people process one problem very effectively, but interferes with seeing connections between those problems. In this case, they don’t see why mods 1 and 2 are working in opposition to each other.

From the outside–to someone who encounters both thoughts at once and so doesn’t process them separately–it makes no sense that someone could advocate both at once. They obviously contradict. Hence, outsiders tend to assume this contradiction is deliberate, caused by conspiracy, malice, or ill-will.

(Don’t worry, this is the last of the vacation posting.)

A Modest Educational Proposal


Fellow humans, we have a problem. (And another problem.)

At least, this looks like a problem to me., especially when I’m trying to make conversation at the local moms group.

There are many potential reasons the data looks like this (including inaccuracy, though my lived experience says it is accurate.) Our culture encourages people to limit their fertility, and smart women are especially so encouraged. Smart people are also better at long-term planning and doing things like “reading the instructions on the birth control.”

But it seems likely that there is another factor, an arrow of causation pointing in the other direction: smart people tend to stay in school for longer, and people dislike having children while they are still in school. While you are in school, you are in some sense still a child, and we have a notion that children shouldn’t beget children.

Isaac Newton. Never married. Probably a virgin.

People who drop out of school and start having children at 16 tend not to be very smart and also tend to have plenty of children during their child-creating years. People who pursue post-docs into their thirties tend to be very smart–and many of them are virgins.

Now, I don’t know about you, but I kind of like having smart people around, especially the kinds of people who invent refrigerators and make supply chains work so I can enjoy eating food, even though I live in a city, far from any farms. I don’t want to live in a world where IQ is crashing and we can no longer maintain complex technological systems.

We need to completely re-think this system where the smarter you are, the longer you are expected to stay in school, accruing debt and not having children.

Proposal one: Accelerated college for bright students. Let any student who can do college-level work begin college level work for college credits, even if they are still in high (or middle) school. There are plenty of bright students out there who could be completing their degrees by 18.

The entirely framework of schooling probably ought to be sped up in a variety of ways, especially for bright students. The current framework often reflects the order in which various discoveries were made, rather than the age at which students are capable of learning the material. For example, negative numbers are apparently not introduced in the math curriculum until 6th grade, even though, in my experience, even kindergarteners are perfectly capable of understanding the concept of “debt.” If I promise to give you one apple tomorrow, then I have “negative one apple.” There is no need to hide the concept of negatives for 6 years.

Proposal two: More apprenticeship.

In addition to being costly and time-consuming, a college degree doesn’t even guarantee that your chosen field will still be hiring when you graduate. (I know people with STEM degrees who graduated right as the dot.com bubble burst. Ouch.) We essentially want our educational system to turn out people who are highly skilled at highly specialized trades, and capable of turning around and becoming highly skilled at another highly specialized trade on a dime if that doesn’t work out. This leads to chemists returning to university to get law degrees; physicists to go back for medical degrees. We want students to have both “broad educations” so they can get hired anywhere, and “deep educations” so they’ll actually be good at their jobs.

Imagine, instead, a system where highschool students are allowed to take a two-year course in preparation for a particular field, at the end of which high performers are accepted into an apprenticeship program where the continue learning on the job. At worst, these students would have a degree, income, and job experience by the age of 20, even if they decided they now wanted to switch professions or pursue an independent education.

Proposal three: Make childbearing normal for adult students.

There’s no reason college students can’t get married and have children (aside from, obviously, their lack of jobs and income.) College is not more time consuming or physically taxing than regular jobs, and college campuses tend to be pretty pleasant places. Studying while pregnant isn’t any more difficult than working while pregnant.

Grad students, in particular, are old and mature enough to get married and start families, and society should encourage them to do so.

Proposal four: stop denigrating child-rearing, especially for intelligent women.

Children are a lot of work, but they’re also fun. I love being with my kids. They are my family and an endless source of happiness.

What people want and value, they will generally strive to obtain.


These are just some ideas. What are yours?

When did language evolve?

The smartest non-human primates, like Kanzi the bonobo and Koko the gorilla, understand about 2,000 to 4,000 words. Koko can make about 1,000 signs in sign language and Kanzi can use about 450 lexigrams (pictures that stand for words.) Koko can also make some onomatopoetic words–that is, she can make and use imitative sounds in conversation.

A four year human knows about 4,000 words, similar to an exceptional gorilla. An adult knows about 20,000-35,000 words. (Another study puts the upper bound at 42,000.)

Somewhere along our journey from ape-like hominins to homo sapiens sapiens, our ancestors began talking, but exactly when remains a mystery. The origins of writing have been amusingly easy to discover, because early writers were fond of very durable surfaces, like clay, stone, and bone. Speech, by contrast, evaporates as soon as it is heard–leaving no trace for archaeologists to uncover.

But we can find the things necessary for speech and the things for which speech, in turn, is necessary.

The main reason why chimps and gorillas, even those taught human language, must rely on lexigrams or gestures to communicate is that their voiceboxes, lungs, and throats work differently than ours. Their semi-arborial lifestyle requires using the ribs as a rigid base for the arm and shoulder muscles while climbing, which in turn requires closing the lungs while climbing to provide support for the ribs.

Full bipedalism released our early ancestors from the constraints on airway design imposed by climbing, freeing us to make a wider variety of vocalizations.

Now is the perfect time to break out my file of relevant human evolution illustrations:

Source: Scientific American What Makes Humans Special

We humans split from our nearest living ape relatives about 7-8 million years ago, but true bipedalism may not have evolved for a few more million years. Since there are many different named hominins, here is a quick guide:

Source: Macroevolution in and Around the Hominin Clade

Australopithecines (light blue in the graph,) such as the famous Lucy, are believed to have been the first fully bipedal hominins, although, based on the shape of their toes, they may have still occasionally retreated into the trees. They lived between 4 and 2 million years ago.

Without delving into the myriad classification debates along the lines of “should we count this set of skulls as a separate species or are they all part of the natural variation within one species,” by the time the homo genus arises with H Habilis or H. Rudolfensis around 2.8 million years ag, humans were much worse at climbing trees.

Interestingly, one direction humans have continued evolving in is up.

Oldowan tool

The reliable production of stone tools represents an enormous leap forward in human cognition. The first known stone tools–Oldowan–are about 2.5-2.6 million years old and were probably made by homo Habilis. These simple tools are typically shaped only one one side.

By the Acheulean–1.75 million-100,000 years ago–tool making had become much more sophisticated. Not only did knappers shape both sides of both the tops and bottoms of stones, but they also made tools by first shaping a core stone and then flaking derivative pieces from it.

The first Acheulean tools were fashioned by h Erectus; by 100,000 years ago, h Sapiens had presumably taken over the technology.

Flint knapping is surprisingly difficult, as many an archaeology student has discovered.

These technological advances were accompanied by steadily increasing brain sizes.

I propose that the complexities of the Acheulean tool complex required some form of language to facilitate learning and teaching; this gives us a potential lower bound on language around 1.75 million years ago. Bipedalism gives us an upper bound around 4 million years ago, before which our voice boxes were likely more restricted in the sounds they could make.

A Different View

Even though “homo Sapiens” has been around for about 300,000 years (or so we have defined the point where we chose to differentiate between our species and the previous one,) “behavioral modernity” only emerged around 50,000 years ago (very awkward timing if you know anything about human dispersal.)

Everything about behavioral modernity is heavily contested (including when it began,) but no matter how and when you date it, compared to the million years or so it took humans to figure out how to knap the back side of a rock, human technologic advance has accelerated significantly over the past 100,000 and even moreso over the past 50,000 and even 10,000.

Fire was another of humanity’s early technologies:

Claims for the earliest definitive evidence of control of fire by a member of Homo range from 1.7 to 0.2 million years ago (Mya).[1] Evidence for the controlled use of fire by Homo erectus, beginning some 600,000 years ago, has wide scholarly support.[2][3] Flint blades burned in fires roughly 300,000 years ago were found near fossils of early but not entirely modern Homo sapiens in Morocco.[4] Evidence of widespread control of fire by anatomically modern humans dates to approximately 125,000 years ago.[5]

What prompted this sudden acceleration? Noam Chomsky suggests that it was triggered by the evolution of our ability to use and understand language:

Noam Chomsky, a prominent proponent of discontinuity theory, argues that a single chance mutation occurred in one individual in the order of 100,000 years ago, installing the language faculty (a component of the mind–brain) in “perfect” or “near-perfect” form.[6]

(Pumpkin Person has more on Chomsky.)

More specifically, we might say that this single chance mutation created the capacity for figurative or symbolic language, as clearly apes already have the capacity for very simple language. It was this ability to convey abstract ideas, then, that allowed humans to begin expressing themselves in other abstract ways, like cave painting.

I disagree with this view on the grounds that human groups were already pretty widely dispersed by 100,000 years ago. For example, Pygmies and Bushmen are descended from groups of humans who had already split off from the rest of us by then, but they still have symbolic language, art, and everything else contained in the behavioral modernity toolkit. Of course, if a trait is particularly useful or otherwise successful, it can spread extremely quickly (think lactose tolerance,) and neither Bushmen nor Pygmies were 100% genetically isolated for the past 250,000 years, but I simply think the math here doesn’t work out.

However, that doesn’t mean Chomsky isn’t on to something. For example, Johanna Nichols (another linguist,) used statistical models of language differentiation to argue that modern languages split around 100,000 years ago.[31] This coincides neatly with the upper bound on the Out of Africa theory, suggesting that Nichols may actually have found the point when language began differentiating because humans left Africa, or perhaps she found the origin of the linguistic skills necessary to accomplish humanity’s cross-continental trek.

Philip Lieberman and Robert McCarthy looked at the shape of Neanderthal, homo Erectus, early h Sapiens and modern h Sapiens’ vocal tracts:

In normal adults these two portions of the SVT form a right angle to one another and are approximately equal in length—in a 1:1 proportion. Movements of the tongue within this space, at its midpoint, are capable of producing tenfold changes in the diameter of the SVT. These tongue maneuvers produce the abrupt diameter changes needed to produce the formant frequencies of the vowels found most frequently among the world’s languages—the “quantal” vowels [i], [u], and [a] of the words “see,” “do,” and “ma.” In contrast, the vocal tracts of other living primates are physiologically incapable of producing such vowels.

(Since juvenile humans are shaped differently than adults, they pronounce sounds slightly differently until their voiceboxes fully develop.)

Their results:

…Neanderthal necks were too short and their faces too long to have accommodated equally proportioned SVTs. Although we could not reconstruct the shape of the SVT in the Homo erectus fossil because it does not preserve any cervical vertebrae, it is clear that its face (and underlying horizontal SVT) would have been too long for a 1:1 SVT to fit into its head and neck. Likewise, in order to fit a 1:1 SVT into the reconstructed Neanderthal anatomy, the larynx would have had to be positioned in the Neanderthal’s thorax, behind the sternum and clavicles, much too low for effective swallowing. …

Surprisingly, our reconstruction of the 100,000-year-old specimen from Israel, which is anatomically modern in most respects, also would not have been able to accommodate a SVT with a 1:1 ratio, albeit for a different reason. … Again, like its Neanderthal relatives, this early modern human probably had an SVT with a horizontal dimension longer than its vertical one, translating into an inability to reproduce the full range of today’s human speech.

It was only in our reconstruction of the most recent fossil specimens—the modern humans postdating 50,000 years— that we identified an anatomy that could have accommodated a fully modern, equally proportioned vocal tract.

Just as small children who can’t yet pronounce the letter “r” can nevertheless make and understand language, I don’t think early humans needed to have all of the same sounds as we have in order to communicate with each other. They would have just used fewer sounds.

The change in our voiceboxes may not have triggered the evolution of language, but been triggered by language itself. As humans began transmitting more knowledge via language, humans who could make more sounds could utter a greater range of words perhaps had an edge over their peers–maybe they were seen as particularly clever, or perhaps they had an easier time organizing bands of hunters and warriors.

One of the interesting things about human language is that it is clearly simultaneously cultural–which language you speak is entirely determined by culture–and genetic–only humans can produce language in the way we do. Even the smartest chimps and dolphins cannot match our vocabularies, nor imitate our sounds. Human infants–unless they have some form of brain damage–learn language instinctually, without conscious teaching. (Insert reference to Steven Pinker.)

Some kind of genetic changes were obviously necessary to get from apes to human language use, but exactly what remains unclear.

A variety of genes are associated with language use, eg FOXP2. H Sapiens and chimps have different versions of the FOXP2 gene, (and Neanderthals have a third, but more similar to the H Sapiens version than the chimp,) but to my knowledge we have yet to discover exactly when the necessary mutations arose.

Despite their impressive skulls and survival in a harsh, novel climate, Neanderthals seem not to have engaged in much symbolic activity, (though to be fair, they were wiped out right about the time Sapiens really got going with its symbolic activity.) Homo Sapiens and Homo Nanderthalis split around 800-400,000 years ago–perhaps the difference in our language genes ultimately gave Sapiens the upper hand.

Just as farming appears to have emerged relatively independently in several different locations around the world at about the same time, so behavioral modernity seems to have taken off in several different groups around the same time. Of course we can’t rule out the possibility that these groups had some form of contact with each other–peaceful or otherwise–but it seems more likely to me that similar behaviors emerged in disparate groups around the same time because the cognitive precursors necessary for those behaviors had already begun before they split.

Based on genetics, the shape of their larynges, and their cultural toolkits, Neanderthals probably did not have modern speech, but they may have had something similar to it. This suggests that at the time of the Sapiens-Neanderthal split, our common ancestor possessed some primitive speech capacity.

By the time Sapiens and Neanderthals encountered each other again, nearly half a million years later, Sapiens’ language ability had advanced, possibly due to further modification of FOXP2 and other genes like it, plus our newly modified voiceboxes, while Neanderthals’ had lagged. Sapiens achieved behavioral modernity and took over the planet, while Neanderthals disappeared.


Nootropics and Gender

This is a quick post based on my impressions; I’d like to hear if your own, whether similar or different.

Men and women seem to take a different approach to food, medicine, supplements (eg vitamins) and various “chemicals.” Women seem to be–on average, overall–distrustful of “chemicals” and prefer “natural foods” (eg, “organic, free-range chicken”).

I use “”s on the word chemicals because it is not meant literally–water is a chemical, but most of us are okay with drinking water. People say they are opposed to chemicals in their food obviously are not opposed to anything whose molecular structure can be expressed in a formula, like the oxygen we breathe, (chemical formula O2) but opposed to the addition of novel ingredients synthesized in a laboratory or otherwise derived in some manner and then added to food.

Women seem more likely to be anti-vaxers but pro-prozac; men seem more likely to be anti-prozac but pro-nootropics. Men are more likely to order random chemicals they read about on the internet that promise to make them smarter, stronger, or give them better erections, while women are more likely to go to a psychiatrist and ask for medicines to help them concentrate and feel less anxious. Men drink whey protein shakes to help build muscle after working out and women drink detox superfruit smoothies.

A couple of overarching theories: women probably have a stronger instinctual avoidance of food contaminants/poisons, due to weaker bodies and fetuses that have to be protected from poisons. They therefore dislike “chemicals” and “food additives;” “organic” is really a code-word for “pure.”

Vaccines, which are a combination of two contaminants–“chemicals” and actual viruses–which are then administered in a horrifying way (injection), also trips up these purity instincts.

This makes their fondness of anti-depressants (which are also chemicals) rather odd, but I don’t think they have a literal fear of chemicals. (And, obviously, “women who like anti-depressants” and “women who dislike chemicals” aren’t necessarily the same women.) I think there is a mitigating factor though: psychiatric medications are immediately useful (unlike vaccines, which just make you statistically less likely to someday catch Mumps and the like.)

I don’t think most anti-vaxxers dislike doctors so much as vaccines, which weird them out; women use healthcare at a higher rate than men and overall seem to like doctors, including those who hand out psychiatric medications.

Men seem to think of it as good to use medications (alcohol, or random chemicals ordered off the internet) to make themselves stronger, but not as good to use medications (or random chemicals) to make up for weaknesses. They try to make up for weaknesses by just not being weak (pull yourself up by your bootstraps, bro!) By contrast, women don’t take random pills to “make themselves stronger” or better or smarter, but to make up for their weaknesses.

Both groups may be treating the same problems in similar ways, but thinking about them in different ways. EG, anxious women take anti-anxiety drugs, while anxious men drink alcohol or smoke cigarettes. Adult women actually take more concentration-enhancing ADD medication than men, but men seem massively much more likely to take “brain enhancing” nootropics they found on the internet.

So given, say, a stomach/digestion problem, women seem more likely to turn to elimination diets, organic this and that, and avoiding whatever the health mantra of the day says is best to avoid, while men seem more likely to try to route around the problem with digestive enzymes (overall I think very few people turn to digestive enzymes–food is just much more obvious–but the people who do like enzymes seem to be more male.)

Annecdotally, while I was musing about this post out loud, one of my daughters declared that she would “never order random chemicals off the internet and eat them! Ew!” Meanwhile, one of my sons has been throwing pennies into all the local fountains and wishing for “A drink that will make me think a million times faster.”
