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

Source

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.”

Testosterone metabolization, autism, male brain, and female identity

I began this post intending to write about testosterone metabolization in autism and possible connections with transgender identity, but realized halfway through that I didn’t actually know whether the autist-trans connection was primarily male-to-female or female-to-male. I had assumed that the relevant population is primarily MtF because both autists and trans people are primarily male, but both groups do have female populations that are large enough to contribute significantly. Here’s a sample of the data I’ve found so far:

A study conducted by a team of British scientists in 2012 found that of a pool of individuals not diagnosed on the autism spectrum, female-to-male (FTM) transgender people have higher rates of autistic features than do male-to-female (MTF) transgender people or cisgender males and females. Another study, which looked at children and adolescents admitted to a gender identity clinic in the Netherlands, found that almost 8 percent of subjects were also diagnosed with ASD.

Note that both of these studies are looking at trans people and assessing whether or not they have autism symptoms, not looking at autists and asking if they have trans symptoms. Given the characterization of autism as “extreme male brain” and that autism is diagnosed in males at about 4x the rate of females, the fact that there is some overlap between “women who think they think like men” and “traits associated with male thought patterns” is not surprising.

If the reported connection between autism and trans identity is just “autistic women feel like men,” that’s pretty non-mysterious and I just wasted an afternoon.

Though the data I have found so far still does not look directly at autists and ask how many of them have trans symptoms, the wikipedia page devoted to transgender and transsexual computer programmers lists only MtFs and no FtMs. Whether this is a pattern throughout the wider autism community, it definitely seems to be a thing among programmers. (Relevant discussion.)

So, returning to the original post:

Autism contains an amusing contradiction: on the one hand, autism is sometimes characterized as “extreme male brain,” and on the other hand, (some) autists (may be) more likely than neurotypicals to self-identify as transwomen–that is, biological men who see themselves as women. This seems contradictory: if autists are more masculine, mentally, than the average male, why don’t they identify as football players, army rangers, or something else equally masculine? For that matter, why isn’t a group with “extreme male brains” regarded as more, well, masculine?

(And if autists have extreme male brains, does that mean football players don’t? Do football players have more feminine brains than autists? Do colorless green ideas sleep furiously? DO WORDS MEAN?)

*Ahem*

In favor of the “extreme male brain” hypothesis, we have evidence that testosterone is important for certain brain functions, like spacial recognition, we have articles like this one: Testosterone and the brain:

Gender differences in spatial recognition, and age-related declines in cognition and mood, point towards testosterone as an important modulator of cerebral functions. Testosterone appears to activate a distributed cortical network, the ventral processing stream, during spatial cognition tasks, and addition of testosterone improves spatial cognition in younger and older hypogonadal men. In addition, reduced testosterone is associated with depressive disorders.

(Note that women also suffer depression at higher rates than men.)

So people with more testosterone are better at spacial cognition and other tasks that “autistic” brains typically excel at, and brains with less testosterone tend to be moody and depressed.

But hormones are tricky things. Where do they come from? Where do they go? How do we use them?

According to Wikipedia:

During the second trimester [of pregnancy], androgen level is associated with gender formation.[13] This period affects the femininization or masculinization of the fetus and can be a better predictor of feminine or masculine behaviours such as sex typed behaviour than an adult’s own levels. A mother’s testosterone level during pregnancy is correlated with her daughter’s sex-typical behavior as an adult, and the correlation is even stronger than with the daughter’s own adult testosterone level.[14]

… Early infancy androgen effects are the least understood. In the first weeks of life for male infants, testosterone levels rise. The levels remain in a pubertal range for a few months, but usually reach the barely detectable levels of childhood by 4–6 months of age.[15][16] The function of this rise in humans is unknown. It has been theorized that brain masculinization is occurring since no significant changes have been identified in other parts of the body.[17] The male brain is masculinized by the aromatization of testosterone into estrogen, which crosses the blood–brain barrier and enters the male brain, whereas female fetuses have α-fetoprotein, which binds the estrogen so that female brains are not affected.[18]

(Bold mine.)

Let’s re-read that: the male brain is masculinized by the aromatization of testosterone into estrogen.

If that’s not a weird sentence, I don’t know what is.

Let’s hop over to the scientific literature, eg, Estrogen Actions in the Brain and the Basis for Differential Action in Men and Women: A Case for Sex-Specific Medicines:

Burgeoning evidence now documents profound effects of estrogens on learning, memory, and mood as well as neurodevelopmental and neurodegenerative processes. Most data derive from studies in females, but there is mounting recognition that estrogens play important roles in the male brain, where they can be generated from circulating testosterone by local aromatase enzymes or synthesized de novo by neurons and glia. Estrogen-based therapy therefore holds considerable promise for brain disorders that affect both men and women. However, as investigations are beginning to consider the role of estrogens in the male brain more carefully, it emerges that they have different, even opposite, effects as well as similar effects in male and female brains. This review focuses on these differences, including sex dimorphisms in the ability of estradiol to influence synaptic plasticity, neurotransmission, neurodegeneration, and cognition, which, we argue, are due in a large part to sex differences in the organization of the underlying circuitry.

Hypothesis: the way testosterone works in the brain (where we both do math and “feel” male or female) and the way it works in the muscles might be very different.

Do autists actually differ from other people in testosterone (or other hormone) levels?

In Elevated rates of testosterone-related disorders in women with autism spectrum conditions, researchers surveyed autistic women and mothers of autistic children about various testosterone-related medical conditions:

Compared to controls, significantly more women with ASC [Autism Spectrum Conditions] reported (a) hirsutism, (b) bisexuality or asexuality, (c) irregular menstrual cycle, (d) dysmenorrhea, (e) polycystic ovary syndrome, (f) severe acne, (g) epilepsy, (h) tomboyism, and (i) family history of ovarian, uterine, and prostate cancers, tumors, or growths. Compared to controls, significantly more mothers of ASC children reported (a) severe acne, (b) breast and uterine cancers, tumors, or growths, and (c) family history of ovarian and uterine cancers, tumors, or growths.

Androgenic Activity in Autism has an unfortunately low number of subjects (N=9) but their results are nonetheless intriguing:

Three of the children had exhibited explosive aggression against others (anger, broken objects, violence toward others). Three engaged in self-mutilations, and three demonstrated no aggression and were in a severe state of autistic withdrawal. The appearance of aggression against others was associated with having fewer of the main symptoms of autism (autistic withdrawal, stereotypies, language dysfunctions).

Three of their subjects (they don’t say which, but presumably from the first group,) had abnormally high testosterone levels (including one of the girls in the study.) The other six subjects had normal androgen levels.

This is the first report of an association between abnormally high androgenic activity and aggression in subjects with autism. Although a previously reported study did not find group mean elevations in plasma testosterone in prepubertal autistic subjects (4), it appears here that in certain autistic individuals, especially those in puberty, hyperandrogeny may play a role in aggressive behaviors. Also, there appear to be distinct clinical forms of autism that are based on aggressive behaviors and are not classified in DSM-IV. Our preliminary findings suggest that abnormally high plasma testosterone concentration is associated with aggression against others and having fewer of the main autistic symptoms.

So, some autists have do have abnormally high testosterone levels, but those same autists are less autistic, overall, than other autists. More autistic behavior, aggression aside, is associated with normal hormone levels. Probably.

But of course that’s not fetal or early infancy testosterone levels. Unfortunately, it’s rather difficult to study fetal testosterone levels in autists, as few autists were diagnosed as fetuses. However, Foetal testosterone and autistic traits in 18 to 24-month-old children comes close:

Levels of FT [Fetal Testosterone] were analysed in amniotic fluid and compared with autistic traits, measured using the Quantitative Checklist for Autism in Toddlers (Q-CHAT) in 129 typically developing toddlers aged between 18 and 24 months (mean ± SD 19.25 ± 1.52 months). …

Sex differences were observed in Q-CHAT scores, with boys scoring significantly higher (indicating more autistic traits) than girls. In addition, we confirmed a significant positive relationship between FT levels and autistic traits.

I feel like this is veering into “we found that boys score higher on a test of male traits than girls did” territory, though.

In Polymorphisms in Genes Involved in Testosterone Metabolism in Slovak Autistic Boys, researchers found:

The present study evaluates androgen and estrogen levels in saliva as well as polymorphisms in genes for androgen receptor (AR), 5-alpha reductase (SRD5A2), and estrogen receptor alpha (ESR1) in the Slovak population of prepubertal (under 10 years) and pubertal (over 10 years) children with autism spectrum disorders. The examined prepubertal patients with autism, pubertal patients with autism, and prepubertal patients with Asperger syndrome had significantly increased levels of salivary testosterone (P < 0.05, P < 0.01, and P < 0.05, respectively) in comparison with control subjects. We found a lower number of (CAG)n repeats in the AR gene in boys with Asperger syndrome (P < 0.001). Autistic boys had an increased frequency of the T allele in the SRD5A2 gene in comparison with the control group. The frequencies of T and C alleles in ESR1 gene were comparable in all assessed groups.

What’s the significance of CAG repeats in the AR gene? Apparently they vary inversely with sensitivity to androgens:

Individuals with a lower number of CAG repeats exhibit higher AR gene expression levels and generate more functional AR receptors increasing their sensitivity to testosterone…

Fewer repeats, more sensitivity to androgens. The SRD5A2 gene is also involved in testosterone metabolization, though I’m not sure exactly what the T allele does relative to the other variants.

But just because there’s a lot of something in the blood (or saliva) doesn’t mean the body is using it. Diabetics can have high blood sugar because their bodies lack the necessary insulin to move the sugar from the blood, into their cells. Fewer androgen receptors could mean the body is metabolizing testosterone less effectively, which in turn leaves more of it floating in the blood… Biology is complicated.

What about estrogen and the autistic brain? That gets really complicated. According to Sex Hormones in Autism: Androgens and Estrogens Differentially and Reciprocally Regulate RORA, a Novel Candidate Gene for Autism:

Here, we show that male and female hormones differentially regulate the expression of a novel autism candidate gene, retinoic acid-related orphan receptor-alpha (RORA) in a neuronal cell line, SH-SY5Y. In addition, we demonstrate that RORA transcriptionally regulates aromatase, an enzyme that converts testosterone to estrogen. We further show that aromatase protein is significantly reduced in the frontal cortex of autistic subjects relative to sex- and age-matched controls, and is strongly correlated with RORA protein levels in the brain.

If autists are bad at converting testosterone to estrogen, this could leave extra testosterone floating around in their blood… but doens’t explain their supposed “extreme male brain.” Here’s another study on the same subject, since it’s confusing:

Comparing the brains of 13 children with and 13 children without autism spectrum disorder, the researchers found a 35 percent decrease in estrogen receptor beta expression as well as a 38 percent reduction in the amount of aromatase, the enzyme that converts testosterone to estrogen.

Levels of estrogen receptor beta proteins, the active molecules that result from gene expression and enable functions like brain protection, were similarly low. There was no discernable change in expression levels of estrogen receptor alpha, which mediates sexual behavior.

I don’t know if anyone has tried injecting RORA-deficient mice with estrogen, but here is a study about the effects of injecting reelin-deficient mice with estrogen:

The animals in the new studies, called ‘reeler’ mice, have one defective copy of the reelin gene and make about half the amount of reelin compared with controls. …

Reeler mice with one faulty copy serve as a model of one of the most well-established neuro-anatomical abnormalities in autism. Since the mid-1980s, scientists have known that people with autism have fewer Purkinje cells in the cerebellum than normal. These cells integrate information from throughout the cerebellum and relay it to other parts of the brain, particularly the cerebral cortex.

But there’s a twist: both male and female reeler mice have less reelin than control mice, but only the males lose Purkinje cells. …

In one of the studies, the researchers found that five days after birth, reeler mice have higher levels of testosterone in the cerebellum compared with genetically normal males3.

Keller’s team then injected estradiol — a form of the female sex hormone estrogen — into the brains of 5-day-old mice. In the male reeler mice, this treatment increases reelin levels in the cerebellum and partially blocks Purkinje cell loss. Giving more estrogen to female reeler mice has no effect — but females injected with tamoxifen, an estrogen blocker, lose Purkinje cells. …

In another study, the researchers investigated the effects of reelin deficiency and estrogen treatment on cognitive flexibility — the ability to switch strategies to solve a problem4. …

“And we saw indeed that the reeler mice are slower to switch. They tend to persevere in the old strategy,” Keller says. However, male reeler mice treated with estrogen at 5 days old show improved cognitive flexibility as adults, suggesting that the estrogen has a long-term effect.

This still doesn’t explain why autists would self-identify as transgender women (mtf) at higher rates than average, but it does suggest that any who do start hormone therapy might receive benefits completely independent of gender identity.

Let’s stop and step back a moment.

Autism is, unfortunately, badly defined. As the saying goes, if you’ve met one autist, you’ve met one autist. There are probably a variety of different, complicated things going on in the brains of different autists simply because a variety of different, complicated conditions are all being lumped together under a single label. Any mental disability that can include both non-verbal people who can barely dress and feed themselves and require lifetime care and billionaires like Bill Gates is a very badly defined condition.

(Unfortunately, people diagnose autism with questionnaires that include questions like “Is the child pedantic?” which could be equally true of both an autistic child and a child who is merely very smart and has learned more about a particular subject than their peers and so is responding in more detail than the adult is used to.)

The average autistic person is not a programmer. Autism is a disability, and the average diagnosed autist is pretty darn disabled. Among the people who have jobs and friends but nonetheless share some symptoms with formally diagnosed autists, though, programmer and the like appear to be pretty popular professions.

Back in my day, we just called these folks nerds.

Here’s a theory from a completely different direction: People feel the differences between themselves and a group they are supposed to fit into and associate with a lot more strongly than the differences between themselves and a distant group. Growing up, you probably got into more conflicts with your siblings and parents than with random strangers, even though–or perhaps because–your family is nearly identical to you genetically, culturally, and environmentally. “I am nothing like my brother!” a man declares, while simultaneously affirming that there is a great deal in common between himself and members of a race and culture from the other side of the planet. Your  coworker, someone specifically selected for the fact that they have similar mental and technical aptitudes and training as yourself, has a distinct list of traits that drive you nuts, from the way he staples papers to the way he pronounces his Ts, while the women of an obscure Afghan tribe of goat herders simply don’t enter your consciousness.

Nerds, somewhat by definition, don’t fit in. You don’t worry much about fitting into a group you’re not part of in the fist place–you probably don’t worry much about whether or not you fit in with Melanesian fishermen–but most people work hard at fitting in with their own group.

So if you’re male, but you don’t fit in with other males (say, because you’re a nerd,) and you’re down at the bottom of the highschool totem pole and feel like all of the women you’d like to date are judging you negatively next to the football players, then you might feel, rather strongly, the differences between you and other males. Other males are aggressive, they call you a faggot, they push you out of their spaces and threaten you with violence, and there’s very little you can do to respond besides retreat into your “nerd games.”

By contrast, women are polite to you, not aggressive, and don’t aggressively push you out of their spaces. Your differences with them are much less problematic, so you feel like you “fit in” with them.

(There is probably a similar dynamic at play with American men who are obsessed with anime. It’s not so much that they are truly into Japanese culture–which is mostly about quietly working hard–as they don’t fit in very well with their own culture.) (Note: not intended as a knock on anime, which certainly has some good works.)

And here’s another theory: autists have some interesting difficulties with constructing categories and making inferences from data. They also have trouble going along with the crowd, and may have fewer “mirror neurons” than normal people. So maybe autists just process the categories of “male” and “female” a little differently than everyone else, and in a small subset of autists, this results in trans identity.*

And another: maybe there are certain intersex disorders which result in differences in brain wiring/organization. (Yes, there are real interesx disorders, like Klinefelter’s, in which people have XXY chromosomes instead of XX or XY.) In a small set of cases, these unusually wired brains may be extremely good at doing certain tasks (like programming) resulting people who are both “autism spectrum” and “trans”. This is actually the theory I’ve been running with for years, though it is not incompatible with the hormonal theories discussed above.

But we are talking small: trans people of any sort are extremely rare, probably on the order of <1/1000. Even if autists were trans at 8 times the rates of non-autists, that’s still only 8/1000 or 1/125. Autists themselves are pretty rare (estimates vary, but the vast majority of people are not autistic at all,) so we are talking about a very small subset of a very small population in the first place. We only notice these correlations at all because the total population has gotten so huge.

Sometimes, extremely rare things are random chance.

Book on a Friday: Squid Empire: The Rise and Fall of the Cephalopods by Danna Staaf

Danna Staaf’s Squid Empire: The Rise and Fall of the Cephalopods is about the evolution of squids and their relatives–nautiluses, cuttlefish, octopuses, ammonoids, etc. If you are really into squids or would like to learn more about squids, this is the book for you. If you aren’t big on reading about squids but want something that looks nice on your coffee table and matches your Cthulhu, Flying Spaghetti Monster, and 20,000 Leagues Under the Sea decor, this is the book for you. If you aren’t really into squids, you probably won’t enjoy this book.

Squids, octopuses, etc. are members of the class of cephalopods, just as you are a member of the class of mammals. Mammals are in the phylum of chordates; cephalopods are mollusks. It’s a surprising lineage for one of Earth’s smartest creatures–80% mollusk species are slugs and snails. If you think you’re surrounded by idiots, imagine how squids must feel.

The short story of cephalopodic evolution is that millions upon millions of years ago, most life was still stuck at the bottom of the ocean. There were some giant microbial mats, some slugs, some snails, some worms, and not a whole lot else. One of those snails figured out how to float by removing some of the salt from the water inside its shell, making itself a bit buoyant. Soon after its foot (all mollusks have a “foot”) split into multiple parts. The now-floating snail drifted over the seafloor, using its new tentacles to catch and eat the less-mobile creatures below it.

From here, cephalopods diversified dramatically, creating the famous ammonoids of fossil-dating lore.

Cross-section of a fossilized ammonite shell, revealing internal chambers and septa

Ammonoids are known primarily from their shells (which fossilize well) rather than their fleshy tentacle parts, (which fossilize badly). But shells we have in such abundance they can be easily used for dating other nearby fossils.

Ammonoids are obviously similar to their cousins, the lovely chambered nautiluses. (Please don’t buy nautilus shells; taking them out of their shells kills them and no one farms nautiluses so the shell trade is having a real impact on their numbers. We don’t need their shells, but they do.)

Ammonoids succeeded for millions of years, until the Creatceous extinction event that also took out the dinosaurs. The nautiluses survived–as the author speculates, perhaps because they lay large eggs with much more yolk that develop very slowly, infant nautiluses were able to wait out the event while ammonoids, with their fast-growing, tiny eggs dependent on feeding immediately after hatching simply starved in the upheaval.

In the aftermath, modern squids and octopuses proliferated.

How did we get from floating, shelled snails to today’s squishy squids?

The first step was internalization–cephalopods began growing their fleshy mantles over their shells instead of inside of them–in essence, these invertebrates became vertebrates. Perhaps this was some horrible genetic accident, but it worked out. These internalized shells gradually became smaller and thinner, until they were reduced to a flexible rod called a “pen” that runs the length of a squid’s mantle. (Cuttlefish still retain a more substantial bone, which is frequently collected on beaches and sold for birds to peck at for its calcium.)

With the loss of the buoyant shell, squids had to find another way to float. This they apparently achieved by filling themselves with ammonia salts, which makes them less dense than water but also makes their decomposition disgusting and renders them unfossilizable because they turn to mush too quickly. Octopuses, by contrast, aren’t full of ammonia and so can fossilize.

Since the book is devoted primarily to cephalopod evolution rather than modern cephalopods, it doesn’t go into much depth on the subject of their intelligence. Out of all the invertebrates, cephalopods are easily the most intelligent (perhaps really the only intelligent invertebrates). Why? If cephalopods didn’t exist, we might easily conclude that invertebrates can’t be intelligent–invertebrateness is somehow inimical to intelligence. After all, most invertebrates are about as intelligent as slugs. But cephalopods do exist, and they’re pretty smart.

The obvious answer is that cephalopods can move and are predatory, which requires bigger brains. But why are they the only invertebrates–apparently–who’ve accomplished the task?

But enough jabber–let’s let Mrs. Staaf speak:

I find myself obliged to address the perennial question: “octopuses” or “octopi”? Or, heaven help us, “octopodes”?

Whichever you like best. Seriously. Despite what you may have heard, “octopus” is neither ancient Greek nor Latin. Aristotle called the animal polypous for its “many feet.” The ancient Romans borrowed this word and latinized the spelling to polypus. It was much later that a Renaissance scientists coined and popularized the word “octopus,” using Greek roots for “eight” and “foot” but Latin spelling.

If the word had actually been Greek, it would be spelled octopous and pluralized octopodes. If translated into Latin, it might have become octopes and pluralized octopedes,  but more likely the ancient Roman would have simply borrowed the Greek word–as they did with poly pus. Those who perhaps wished to appear erudite used the Greek plural polypodes, while others favored a Latin ending and pluralized it polypi.

The latter is a tactic we English speakers emulate when we welcome “octopus” into our own language and pluralize it “octopuses” as I’ve chosen to do.

There. That settles it.

Dinosaurs are the poster children for evolution and extinction writ large…

Of course, not all of them did die. We know now that birds are simply modern dinosaurs, but out of habit we tend to reserve the word “dinosaur for the hug ancient creatures that went extinct at the end of the Cretaceous. After all, even if they had feathers, they seem so different from today’s finches and robins. For one thing, the first flying feathered dinosaurs all seem to have had four wings. There aren’t any modern birds with four wings.

Wesl… actually, domestic pigeons can be bred to grow feathers on their legs. Not fuzzy down, but long flight feathers, and along with these feathers their leg bones grow more winglike. The legs are still legs’ they can’t be used to fly like wings. They do, however, suggest a clear step along the road from four-winged dinosaurs to two-winged birds. The difference between pigeons with ordinary legs and pigeons with wing-legs is created by control switches in their DNA that alter the expression of two particular genes. These genes are found in all birds, indeed in all vertebrates,and so were most likely present in dinosaurs as well.

…and I’ve just discovered that almost all of my other bookmarks fell out of the book. Um.

So squid brains are shaped like donuts because their eating/jet propulsion tube runs through the middle of their bodies and thus through the middle of their brains. It seems like this could be a problem if the squid eats too much or eats something with sharp bits in it, but squids seem to manage.

Squids can also leap out of the water and fly through the air for some ways. Octopuses can carry water around in their mantles, allowing them to move on dry land for a few minutes without suffocating.

Since cephalopods are somewhat unique among mollusks for their ability to move quickly, they have a lot in common, genetically, with vertebrates. In essence, they are the most vertebrate-behaving of the mollusks. Convergent evolution.

The vampire squid, despite its name, is actually more of an octopus.

Let me quote from the chapter on sex and babies:

This is one arena in which cephalopods, both ancient and modern, are actually less alien than many aliens–even other mollusks. Slugs, for instance, are hermaphroditic, and in the course of impregnating each other their penises sometimes get tangled, so they chew them off. Nothing in the rest of this chapter will make you nearly that uncomfortable. …

The lovely argonaut octopus

In one living coleoid species, however, sex is blindingly obvious. Females of the octopus known as an argonaut are five times larger than males. (A killer whale is about five times larger than an average adult human, which in turn is about five times large than an opossum.)

This enormous size differential caught the attention of paleontologists who had noticed that many ammonoid species also came in two distinct size, which htey had dubbed microconch (little shell) and macroconch (big shell). Bot were clearly mature, as they had completed the juvenile part of the shell and constructed the final adult living chamber. After an initial flurry of debate, most researchers agreed to model ammonoid sex on modern argonauts, and began to call macroconchs females and microconcs males.

Some fossil nautiloids also come in macroconch and microchonch flavors, though it’s more difficult to be certain that both are adults…

However, the shells of modern nautiluses show the opposite pattern–males are somewhat large than females… Like the nautiloid shift from ten arms to many tens of arms, the pattern could certainly have evolved from a different ancestral condition. If we’re going to make that argument, though, we have to wonder when nautliloids switched from females to males as the larger sex, and why.

In modern species that have larger females, we usually assume the size difference has to do with making or brooding a lot of eggs.Female argonauts take it up a notch and actually secrete a shell-like brood chamber from their arms, using it to cradle numerous batch of eggs over their lifetime. meanwhile, each tiny male argonaut get ot mate only once. His hectocotylus is disposable–after being loaded with sperm and inserted into the female, it breaks off. …

By contrast, when males are the bigger sex, we often guess that the purpose is competition. Certainly many species of squid and cuttlefish have large males that battle for female attention on the mating grounds. They display outrageous skin patterns as they push, shove, and bite each other. Females do appear impressed; at least, they mate with the winning males and consent to be guarded by them. Even in these species, though, there are some mall males who exhibit a totally different mating strategy. While the big males strut their stuff, these small males quietly sidle up to the females, sometimes disguising themselves with female color patterns. This doesn’t put off the real females, who readily mate with these aptly named “sneaker males.” By their very nature, such obfuscating tactics are virtually impossible to glean from the fossil record…

More on octopus mating habits.

This, of course, reminded me of this graph:

In the majority of countries, women are more likely to be overweight than men (suggesting that our measure of “overweight” is probably flawed.) In some countries women are much more likely to be overweight, while in some countries men and women are almost equally likely to be overweight, and in just a few–the Czech Republic, Germany, Hungary, Japan, and barely France, men are more likely to be overweight.

Is there any rhyme or reason to this pattern? Surely affluence is related, but Japan, for all of its affluence, has very few overweight people at all, while Egypt, which is pretty poor, has far more overweight people. (A greater % of Egyptian women are overweight than American women, but American men are more likely to be overweight than Egyptian men.)

Of course, male humans are still–in every country–larger than females. Even an overweight female doesn’t necessarily weigh more than a regular male. But could the variation in male and female obesity rates have anything to do with historic mating strategies? Or is it completely irrelevant?

Back to the book:

Coleoid eyes are as complex as our own, with a lens for focusing light, a retina to detect it, and an iris to sharpen the image. … Despite their common complexity, though, there are some striking differences [between our and squid eyes]. For Example, our retina has a blind spot whee a bundle of nerves enters the eyeball before spreading out to connect to the font of every light receptor. By contrast, light receptors in the coleoid retina are innervated from behind, so there’s no “hole” or blind spot. Structural differences like this how that the two groups converged on similar solution through distinct evolutionary pathways.

Another significant difference is that fish went on to evolve color vision by increasing the variety of light-sensitive proteins in their eyes; coleoids never did and are probably color blind. I say “probably ” because the idea of color blindness in such colorful animals has flummoxed generations of scientists…

“I’m really more of a cuddlefish”

Color-blind or not, coleoids can definitely see something we humans are blind to: the polarization of light.

Sunlight normally consists of waves vibrating in all directions. but when these waves are reflected off certain surface, like water, they get organized and arrive at the retina vibrating in only one direction. We call this “glare” and we don’t like it, so we invented polarized sunglasses. … That’s pretty much all polarized sunglasses can do–block polaraized light. Sadly, they can’t help you decode the secret messages of cuttlefish, which have the ability to perform a sort of double0-talk with their skin, making color camouflage for the befit of polarization-blind predators while flashing polarized displays to their fellow cuttlefish.

That’s amazing. Here’s an article with more on cuttlefish vision and polarization.

Overall, I enjoyed this book. The writing isn’t the most thrilling, but the author has a sense of humor and a deep love for her subject. I recommend it to anyone with a serious hankering to know more about the evolution of squids, or who’d like to learn more about an ancient animal besides dinosaurs.

The Facsimile of Meaning

Most of the activities our ancestors spent the majority of their time on have been automated or largely replaced by technology. Chances are good that the majority of your great-great grandparents were farmers, but few of us today hunt, gather, plant, harvest, or otherwise spend our days physically producing food; few of us will ever build our own houses or even sew our own clothes.

Evolution has (probably) equipped us with neurofeedback loops that reward us for doing the sorts of things we need to do to survive, like hunt down prey or build shelters (even chimps build nests to sleep in,) but these are precisely the activities that we have largely automated and replaced. The closest analogues to these activities are now shopping, cooking, exercising, working on cars, and arts and crafts. (Even warfare has been largely replaced with professional sports fandom.)

Society has invented vicarious thrills: Books, movies, video games, even roller coasters. Our ability to administer vicarious emotions appears to be getting better and better.

And yet, it’s all kind of fake.

Exercising, for example, is in many ways a pointless activity–people literally buy machines so they can run in place. But if you have a job that requires you to be sedentary for most of the day and don’t fancy jogging around your neighborhood after dark, running in place inside your own home may be the best option you have for getting the post-running-down prey endorphin hit that evolution designed you to crave.

A sedentary lifestyle with supermarkets and restaurants deprives us of that successful-hunting endorphin hit and offers us no logical reason to go out and get it. But without that exercise, not only our physical health, but our mental health appears to suffer. According to the Mayo Clinic, exercise effectively decreases depression and anxiety–in other words, depression and anxiety may be caused in part by lack of exercise.

So what do we do? We have to make up some excuse and substitute faux exercise for the active farming/gardening/hunting/gathering lifestyles our ancestors lived.

By the way, about 20% of Americans are on psychiatric medications of some sort, [warning PDF] of which anti-depressants are one of the most commonly prescribed:

Overall, the number of Americans on medications used to treat psychological and behavioral disorders has substantially increased since 2001; more than one‐in‐five adults was on at least one
of these medications in 2010, up 22 percent from ten years earlier. Women are far more likely to take a drug to treat a mental health condition than men, with more than a quarter of the adult
female population on these drugs in 2010 as compared to 15 percent of men.

Women ages 45 and older showed the highest use of these drugs overall. …

The trends among children are opposite those of adults: boys are the higher utilizers of these medications overall but girls’ use has been increasing at a faster rate.

This is mind-boggling. 1 in 5 of us is mentally ill, (supposedly,) and the percent for young women in the “prime of their life” years is even higher. (The rates for Native Americans are astronomical.)

Lack of exercise isn’t the only problem, but I wager a decent chunk of it is that our lives have changed so radically over the past 100 years that we are critically lacking various activities that used to make us happy and provide meaning.

Take the rise of atheism. Irrespective of whether God exists or not, many functions–community events, socializing, charity, morality lessons, etc–have historically been done by religious groups. Atheists are working on replacements, but developing a full system that works without the compulsion of religious belief may take a long while.

Sports and video games replace war and personal competition. TV sitcoms replace friendship. Twitter replaces real life conversation. Politics replace friendship, conversation, and religion.

There’s something silly about most of these activities, and yet they seem to make us happy. I don’t think there’s anything wrong with enjoying knitting, even if you’re making toy octopuses instead of sweaters. Nor does there seem to be anything wrong with enjoying a movie or a game. The problem comes when people get addicted to these activities, which may be increasingly likely as our ability to make fake activities–like hyper-realistic special effects in movies–increases.

Given modernity, should we indulge? Or can we develop something better?

Angola and Atomization

Quick excerpt from God of the Rodeo: The Quest for Redemption in Louisiana’s Angola Prison:

Before the rodeo [Terry Hawkins] had graduated out of the fields to the position of fry cook. It was better than being A.D.H.D. (A Dude with a Hoe and a Ditch)–after stirring fried rice or flipping hotcakes on a sove ten feet long, he could grill hamburgers, bag them, and stuff them down his pants to sell in the dorm. Sometimes he snuck out with fried chicken under his shirt and cuts of cheese in his socks. Payment came in cigarettes, the prison’s currency. Later he would stand outside the canteen, and trade a few packs for shampoo or soap or deoderant, or “zoo-zos”–snacks of candy bars or sardines. He knew which guards would allow the stealing, the selling. He made sure to send them plates of fried chicken.

While reading this I thought, “This man has, at least, something to offer his neighbors. He can sell them food, something they’re grateful for. The guy with cheese in his socks and hamburgers in his pants is probably a respected member of his community.”

What do I have to offer my neighbors? I have skills, but they’re only of interest to a corporate employer, my boss. I don’t make anything for sale. I can’t raise a barn or train a horse, and even if I could, my neighbors don’t need these services. Even if I had milk for sale from my personal cow, my neighbors would still prefer to buy their milk at the grocery store.

All of these needs that we used to fill by interacting with our neighbors are now routed through multinational corporations that build their products in immense sweatshops in foreign countries.

I don’t even have to go to the store to buy things if I don’t want to–I can order things online, even groceries.

Beyond the economic, modern prosperity has also eliminated many of the ways (and places) people used to interact. As Lewis Mumford recounts (H/T Wrath of Gnon):

The Bible would have been different without public wells

To sum up the medieval dwelling house, one may say that it was characterized by lack of differentiated space and differentiated function. In the cities, however, this lack of internal differentiation was offset by a completer development of domestic functions in public institutions. Though the house might lack a private bake-oven, there was a public one at the baker’s or the cook-shop. Though it might lack a private bathroom, there was a municipal bath-house. Thought it might lack facilities for isolating and nursing a diseased member, there were numerous public hospitals. … As long as the conditions were rude–when people lived in the open, pissed freely in the garden or the street, bought and sold outdoors, opened their shutters and let in full sunlight–the defects of the house were far less serious than they were under a more refined regime.

Without all of the little, daily things that naturally brought people into contact with each other and knit them into communities, we simply have far fewer reasons to talk. We might think that people could simply make up for these changes by inventing new, leisure-oriented reasons to interact with each other, but so far, they’re struggling:

Americans’ circle of confidants has shrunk dramatically in the past two decades and the number of people who say they have no one with whom to discuss important matters has more than doubled, according to a new study by sociologists at DukeUniversity and the University of Arizona.

“The evidence shows that Americans have fewer confidants and those ties are also more family-based than they used to be,” said Lynn Smith-Lovin, Robert L. Wilson Professor of Sociology at Duke University and one of the authors of “ Social Isolation in America: Changes in Core Discussion Networks Over Two Decades.” …

It compared data from 1985 and 2004 and found that the mean number of people with whom Americans can discuss matters important to them dropped by nearly one-third, from 2.94 people in 1985 to 2.08 in 2004.

Researchers also found that the number of people who said they had no one with whom to discuss such matters more than doubled, to nearly 25 percent. The survey found that both family and non-family confidants dropped, with the loss greatest in non-family connections.

I don’t know about you, but I just don’t trust most people, and most people have given me no reason to trust them.

Existential Caprine

Once

You were

Wild.

Sure,

There were predators

The lions could be confusing

But you were free

goat painting, Herculaneum

Then came men

Faster, smarter than lions

They killed the wolves

Brought you food

(The bread of slavery, they say, is far sweeter than the bread of freedom.)

And shelter

Children were born, safe from wolves, hunger, or cold

and you grew used to man.

Centuries passed

And it seemed you outnumbered the stars

Perhaps your sons disappeared

But was it worse than wolves?

You could almost forget you were once wild

Could you return to the mountains, even if you wanted to?

And as they lead you away

You ask

Did I ever have a choice?

 

To explain: The process of domestication is fascinating. Some animals, like wolves, began associating with humans because they could pick up our scraps. Others, like cats, began living in our cities because they liked eating the vermin we attracted. (You might say the mice, too, are domesticated.) These relationships are obviously mutually beneficial (aside from the mice.)

The animals we eat, though, have a different–more existential–story.

Humans increased the number of wild goats and sheep available for them to eat by eliminating competing predators, like wolves and lions. We brought them food in the winter, built them shelters to keep them warm in the winter, and led them to the best pastures. As a result, their numbers increased.

But, of course, we eat them.

From the goat’s perspective, is it worth it?

There’s a wonderful metaphor in the Bible, enacted every Passover: matzoh.

If you’ve never had it, matzoh tastes like saltines, only worse. It’s the bread of freedom, hastily thrown on the fire, hastily thrown on the fire and carried away.

The bread of slavery tastes delicious. The bread of freedom tastes awful.

1And they took their journey from Elim, and all the congregation of the children of Israel came unto the wilderness of Sin, which is between Elim and Sinai, on the fifteenth day of the second month after their departing out of the land of Egypt. 2And the whole congregation of the children of Israel murmured against Moses and Aaron in the wilderness: 3And the children of Israel said unto them, Would to God we had died by the hand of the LORD in the land of Egypt, when we sat by the flesh pots, and when we did eat bread to the full… Exodus 16

Even if the goats didn’t want to be domesticated, hated it and fought against it, did they have any choice? If the domesticated goats have more surviving children than wild ones, then goats will become domesticated. It’s a simple matter of numbers:

Total Fertility Rate by Country: Purple = 7 children per woman; Blue = 1 child per woman

The future belongs to those who show up.

Which future do you chose?
