Gay marriage didn’t win; traditional marriage lost

From the evolutionist point of view, the point of marriage is the production of children.

Let’s quickly analogize to food. Humans have a tremendous variety of customs, habits, traditions, and taboos surrounding foods. Foods enjoyed in one culture, like pork, crickets, and dog, are regarded as disgusting, immoral, or forbidden in another. Cheese is, at heart, rotten vomit–the enzyme used to make cheese coagulate is actually extracted from a calf’s stomach lining–and yet the average American eats it eagerly.

Food can remind you of your childhood, the best day of your life, the worst day of your life. It can comfort the sick and the mourning, and it accompanies our biggest celebrations of life.

Eh, I’d be happy giving him a microstate and seeing how he does running it.

We eat comfort food, holiday food, even sacrificial food. We have decadent luxuries and everyday staples. Some people, like vegans and ascetics, avoid large classes of food generally eaten by their own society for moral reasons.

People enjoy soda because it has water and calories, but some of us purposefully trick our taste buds by drinking Diet Coke, which delivers the sensation of drinking calories without the calories themselves. We enjoy the taste of calories even when we don’t need any more.

But the evolutionary purpose of eating is to get enough calories and nutrients to survive. If tomorrow we all stopped needing to eat–say, we were all hooked into a Matrix-style click-farm in which all nutrients were delivered automatically via IV–all of the symbolic and emotional content attached to food would wither away.

The extended helplessness of human infants is unique in the animal kingdom. Even elephants, who gestate for an incredible two years and become mature at 18, can stand and begin walking around shortly after birth. Baby elephants are not raised solely by their mothers, as baby rats are, but by an entire herd of related female elephants.

Elephants are remarkable animals, clever, communicative, and caring, who mourn their dead and create art:


But from the evolutionist point of view, the point of elephants’ family systems is still the production of elephant children.

Love is a wonderful, sweet, many-splendored thing, but the purpose of marriage, in all its myriad forms–polygamy, monogamy, polyandry, serial monogamy–is still the production of children.

There are a few societies where marriage as we know it is not really practiced because people depend on alternative kin networks or women can largely provide for themselves. For example, 70% of African American children are born out of wedlock; and among the avuncular Apache:

In the Southwest United States, the Apache tribe practices a form of this, where the uncle is responsible for teaching the children social values and proper behavior while inheritance and ancestry is reckoned through the mother’s family alone. (Modern day influences have somewhat but not completely erased this tradition.)

Despite the long public argument over the validity of gay marriage, very few gay people actually want to get married. Gallop reports that after the Obergefell v. Hodges ruling, the percent of married gay people jumped quickly from 7.9% to 9.5%, but then leveled off, rising to only 9.6% by June 2016.

In contrast, 46% of US adults are married.

Even this number, though, is in sharp decline: in 1960, 72% of adults were married; by 2010, only 51% were.

The situation is similar throughout the Western world. Only 51% of Brits are married. In Italy, the crude marriage rate (the number of new marriages per 1,000 people), has fallen from 7.35 in 1970 to only 4.21 in 2007. Only 58.9% of Japanese are married.

Declining marriage rates across the developed world have been accompanied by declining fertility rates and rising illegitimacy rates:

H/T: Share of Births to Unmarried Mothers by Race

As Wikipedia notes:

Only 2% of [Japanese] births occur outside of marriage[35] (compared to 30-60% in Europe and North America) due to social taboos, legal pressure, and financial hurdles.[32] Half of Japan’s single mothers live below the poverty line, among the highest for OECD countries.[36][37][38][39]

In other words, the Japanese welfare state, while generous, does not encourage single motherhood. Wikipedia also provides a discussion of the causes of declining Japanese marriage rates:

The annual number of marriages has dropped since the early 1970s, while divorces have shown a general upward trend.[29] …

The decline of marriage in Japan, as fewer people marry and do so later in life, is a widely cited explanation for the plummeting birth rate.[29][30][31][32] Although the total fertility rate has dropped since the 1970s (to 1.43 in 2013[33]), birth statistics for married women have remained fairly constant (at around 2.1) and most married couples have two or more children. Economic factors, such as the cost of raising a child, work-family conflicts, and insufficient housing, are the most common reasons for young mothers (under 34) to have fewer children than desired. …

Between 1990 and 2010, the percentage of 50-year-old people who had never married roughly quadrupled for men to 20.1% and doubled for women to 10.6%.[41][42] The Welfare Ministry predicts these numbers to rise to 29% of men and 19.2% of women by 2035.[43] The government’s population institute estimated in 2014 that women in their early 20s had a one-in-four chance of never marrying, and a two-in-five chance of remaining childless.[44]

Recent media coverage has sensationalized surveys from the Japan Family Planning Association and the Cabinet Office that show a declining interest in dating and sexual relationships among young people, especially among men.[44][45][46] However, changes in sexuality and fertility are more likely an outcome of the decline in family formation than its cause.[47][48] Since the usual purpose of dating in Japan is marriage, the reluctance to marry often translates to a reluctance to engage in more casual relationships.[30]

In other words, marriage is functionally about providing a supportive way of raising children. In a society where birth control does not exist, children born out of wedlock tend not to survive, and people can easily get jobs to support their families, people tended to get married and have children. In a society where people do not want children, cannot afford them, are purposefully delaying childbearing as long as possible, or have found ways to provide for them without getting married, people simply see no need for marriage.

“Marriage” ceases to mean what it once did, reserved for old-fashioned romantics and the few lucky enough to afford it.

Mass acceptance of gay marriage did change how people think of marriage, but it’s downstream from what the massive, societal-wide decrease in child-bearing and increase in illegitimacy have done to our ideas about marriage.

Species of Exit: Israel

Israel is–as far as I can tell–one of the sanest, least self-destructive states in the entire West. (Note: this is not to say that I love everything about Israel; this is actually a pretty low bar, given what’s happening everywhere else.) Their people are literate and healthy, they have a per capita GDP of 36.5k, (33rd in the world,) and they’re 18th globally on the Human Development Index. They don’t throw people off of buildings or have public floggings, and despite the fact that they have birth control and the state actually pays for abortions, the Jewish population still has a positive fertility rate:

The fertility rates of Jewish and Arab women were identical for the first time in Israeli history in 2015, according to figures released by the Israel Central Bureau of Statistics on Tuesday….Jewish and Arab women had given birth to an average of 3.13 children as of last year.

According to Newsweek:

This high fertility rate is not simply an artifact of Israel’s growing ultra-Orthodox or Haredi population; the non-Haredi fertility rate is 2.6. (This is, by the way, a far higher fertility rate than that of American Jews, which is 1.9; the replacement rate is 2.3.)

Did you think we were getting through this without a Polandball joke? And they’ve managed to resist getting conquered by their aggressive and numerically superior neighbors several times in the past century.

Not bad for a country that didn’t exist 100 years ago, had to be built from the sand up, and is filled with people whom conventional wisdom holds ought to have been rendered completely useless by multi-generational epigenetic trauma.

Now, yes, Israel does get a lot of support from the US, and who knows what it would look like (or if it would exist at all,) in an alternative timeline where the US ignores it. Israel probably isn’t perfect, just interesting.

Harking back to my Measures of Meaning post, I propose that Israel has 4 things going for it:

Ethiopian Jews
Ethiopian Jewish member of the IDF

1. Israelis have meaningful work. Their work has been, literally, to build and secure their nation. Israelis have had to build almost the entire infrastructure of their country over the past hundred years, from irrigation systems to roads to cities. Today, Tel Aviv is a city with a population of 430,000 people. In 1900, Tel Aviv didn’t exist.

Unlike the US, Israel has a draft: every Israeli citizen, male and female, has to serve in the Israeli army. (Obviously exceptions exist.) This is not seen as state-run slavery but part of making sure the entire society continues to exist, because Israel faces some pretty real threats to its borders.

The IDF even has a special division for autists:

Many autistic soldiers who would otherwise be exempt from military service have found a place in Unit 9900, a selective intelligence squad where their heightened perceptual skills are an asset. …

The relationship is a mutually beneficial one. For these young people, the unit is an opportunity to participate in a part of Israeli life that might otherwise be closed to them. And for the military, it’s an opportunity to harness the unique skill sets that often come with autism: extraordinary capacities for visual thinking and attention to detail, both of which lend themselves well to the highly specialized task of aerial analysis.

picture-5

I suspect–based on personal conversations–that there is something similar in the US military, but have no proof.

My anthropological work suggests that one of the reasons people enter the military is to find meaning in their lives, (though this doesn’t work nearly as well when your country does things like invade completely irrelevant countries you don’t actually care about like Vietnam.)

2. Like I said, Israelis have above-replacement total fertility–meaning that many Israelis hail from large families, with lots of children, siblings, and cousins. Israelis appear to have managed to achieve this in part by subsidizing births (which probably will have some long-term negative effects for them,*) and in part by explicitly advocating high birth rates in order to prevent themselves from being out-bred by the Palestinians and to show that Hitler what for.

*ETA: See the comments for a discussion of dysgenic fertility on Israel.

I have been saving this picture for so long3. Religion is so obviously a unifying force in Israeli life that I don’t think I need to detail it.

What about that fourth thing? Oh yes: Many of the Jews who don’t like the idea of “nations” and “ethno states” and “religion” probably moved to the US instead of Israel. The US got the SJW Jews and Israel got the nationalist Jews.

4. A sense of themselves as a distinct nation. As I’ve discussed before, this is not exactly genetic, due to different Jewish groups having absorbed about 50% of their DNA from the folks around them during the diaspora years, and of course a big part of the country is Arab/Palestinians, but there is still much genetically in common.

There is probably a lot I’m missing.

15han-2-master675Of course there are religious Jews in the US (and their numbers are growing relative to the secular Jewish population.) While Jews as a whole voted 70% for Hillary, only 56% of the Orthodox supported her. (I’ve seen different numbers elsewhere, but these are the ones I’ve been able to find a source for.)

(I suspect that America’s high-IQ secular Jews suffer from being in America instead of Israel. They don’t have religion to guide them, children to focus them, nor (in many cases) meaningful work. Without something positive to work towards, they turn to politics/ideology to provide meaning in their lives, while simultaneously suffering the psychological stress of knowing that the Holocaust was directed at people like them.)

But that’s irrelevant to Israeli Jews.

Long-term, I’m not bullish on Israel, given its precarious location, surrounded by nations that aren’t very fond of it–and I am not offering any opinions about the Israeli/Palestinian situation–but as first world nations go, it at least desires to keep existing.

Open Thread: Scotus

(Who’s a good shark?)

I don’t really do domestic politics, but what do you guys think of Trump’s SCOTUS pick?

c3h0xgsuoaanakvI’ve been working on some material about instincts and thought this was an interesting graph, relevant to my theory that pregnancy/childbirth have a physical (chemical/hormonal) effect on women, causing their mothering instincts to kick in (mothering isn’t nearly as useful before you have kids as after,) which in turn causes a change in attitudes toward abortion.

Obviously the graph proves little, because people who don’t approve of abortion are predisposed to have more children than people who do. What I really want is a time-based graph, measuring attitudes before and after pregnancy. But I’m having trouble finding that.

Pension obligations are doomed
Pension obligations (CA specific?)

And here’s a graph of pension obligations. Pensions: they’ve got serious issues.

On to comments of the week. First I’m reposting Unknown128′s question because I can’t answer it, but maybe one of you folks can:

I wanted to ask what the German Nazis view on IQ and IQ testing was. From what I know they didnt realy percieve intelligence as a very valuable trait in the first place, prefering physical strenght, endurance and “nordic racial traits”. They bred warriors not thinkers. Also one does hear that they banned IQ testing or at least strongly disliked it.

Do you know anything specific?

This has been a relatively low comment week, but awards go to Leonard:

Antifa is American as apple pie. The use of violence to achieve political objectives is nothing new to communists, and America is a communist country. The original communist country. Don’t forget the civil war. Antifa is just updated antisla.

The reason why you’re seeing more antifa stuff now is that the communists have lost control of the Potemkin government. It’s not that they didn’t exist; it’s that rioting did not serve much political purpose. Pressuring Obama from the left was easy enough without violence. So using violence was fairly senseless.

and With the thoughts you’d be thinkin:

My understanding is Antifas evolved or are a subset of anarchist and socialist groups mainly focussed on combating fringe nationalist parties like the National Front (UK) or the Front National (FRA), whatever their equivalents were in other Western Europe countries etc, in the 70s-90s. Honestly they’re just black bloc dickheads who want to pretend they’re fighting Hitler.

The general dressing in black and breaking stuff style of leftwing activisim is known as black blocs. Basically just dress up in black cover your face and break things. I think it was popularised as a tactic originally against groups like the IMF and WTO, in the US at least it was probably due to “The battle for Seattle”, that was opposition to the WTO. You get routine riots and mischief by groups who perform the same behaviour for various left wing causes all around the world. I think Oakland has a lot of those guys behaving like dicks semi-consistently. …

That’s all for now. What are you thinking about?

Judaism as Memetic Model

Judaism is a useful ethno-religion for modeling mitochondrial/viral meme interactions because it is relatively small.

Depending on which study you read, the US has between 4 and 6 million Jews, neatly split into four main groups:

"Jewish Denominational Affiliation" graphic courtesy Pew Research Center.
Jewish Denominational Affiliation” graphic courtesy Pew Research Center.

A bit confusingly, Orthodox are the most conservative and Conservatives are more moderate. Reforms are liberal, and “No denomination” is mostly atheists who are, of course, the most liberal.

Orthodox have a TFR (total fertility rate, or children per woman,) of 4.1.

Conservatives have a TFR of 1.8.

Reform have a TFR of 1.7.

Atheist Jews have a TFR of 1.5. (source)

(Here I have to stop and point out an error in the source, which claims that “TFR”=total number of children per adult, when TFR is defined as childen per woman. The US TFR of 2.2 means the average woman has 2.2 kids, not that the average woman has 4.4 kids.)

Back to our data. We can see immediately that only Orthodox Jews have a TFR above replacement (approximately 2.) Let’s run through the numbers, just for fun (using a compromise starting number of 5 million total Jews):

Generation 1: 500,000 Orthodox Jews; 900,000 Conservative Jews; 1.75 million Reform Jews; and 1.5 million atheist Jews.

Generation 2: 1,010,000 Orthodox; 810,000 Conservative; 1.488 million Reform; and 1.125 million atheist Jews.

If this trend continued, by Generation 5 we’d have: 8.8 million Orthodox; 530,000 Conservative; 776,000 Reform; and 356,000 atheist. From 10% Orthodox to 84% in just a century; from 30% to 3% atheist.

In reality, though, this doesn’t happen, because many of the children of Orthodox Jews don’t stay Orthodox: “Fewer than half of Jews raised in Orthodox homes have remained Orthodox, with more than 20 percent leaving the religion altogether.”

But this finding requires a caveat, the authors are quick to add: those who left Orthodoxy in droves came of age in the 1950s, 1960s, and 1970s. The 1980s and 1990s have been a lot kinder to the Orthodox denomination; fully 83 percent of respondents between the ages of 18 and 29 who were raised Orthodox are still Orthodox.

!! If that doesn’t look like the less-devout boiling off, leaving a more genetically-inclined-to-Orthodoxy core, I don’t know what does.

Among Jews who were raised Conservative, the number who have left Jewish observance rises to 30 percent; among Jews raised Reform, 35 percent.

Notice that no one talks about Reform Jews becoming Orthodox, because very few do. Orthodox Jews may know how to have children, but their beliefs are simply unattractive to anyone who isn’t raised Orthodox. By contrast, Reform Jews can’t replenish themselves, but their ideas are attractive to non-Reform Jews.

In other words, Orthodoxy is mitochondrial; Reform and atheist Judaism are viral.

Here’s a graph for you:

I love a good graph.

Okay. So let’s recalculate Generation 2:

1,010,000 Orthodox => 48% O, 15%C, 11% R, and 26% A (as a practical matter, “no denomination” is pretty darn close to atheist,) or 485,000 O; 152,ooo C; 111,000 R; and 263,000 A +

810,000 Conservative => 4% O, 36% C, 30% R, 30% A, or 32,000 O; 292,000 C; 243,000 R; 243,000 A.

1.488 million Reform => 1% O, 6% C, 55% R, 37% A, or 15,000 O; 89,000 C; 818,000 R; 551,000 A.

and 1.125 million atheist Jews => mostly atheists.

For a total of 532,000 O; 533,000 C; 1,172,000 R; 2,182,000 A.  In case you’ve forgotten, Gen 1 had:

500,000 O; 900,000 C; 1,750,000 R; and 1,500,000 A.

The numbers aren’t extreme (which makes sense, since the average TFR is close to 2,) but notably, even though 52% of Orthodox children elected to go be something else, Orthodox is the only Jewish denomination that actually managed to grow. Conservative and Reform numbers, despite influxes from Orthodox Judaism, (and, for Reform, from Conservatives,) fell. Atheist Jews, of course, had a significant rise.

Carry on this pattern for several generations, and you get a Judaism that is increasingly split between Orthodox on one hand and atheism on the other.

Now suppose that the more recently observed trend of younger people staying Orthodox at higher rates than previous generations holds true, and the future looks even grimmer for the Conservatives. I’m not going to work out the math, because you can probably estimate for yourself what an 83% retention rate combined with a 4.1 TFR looks like–a very Orthodox Judaism. And very atheist.

I suspect that Christianity (at least white, American Christianity; Ugandan Christianity is totally beyond my knowledge zone,)  is following a similar pattern, with a large increase in atheists on the one hand, massive losses from the moderate center, and the most conservative elements almost hanging on:

I wanted a graph that went back further in time, but this is what I found.
Courtesy of Pew Research Center, “America’s Changing Religious Landscape

I suspect that the “unaffiliateds” include both atheists and people who believe in god or spirituality in some sort of vague way, but not enough to actually attend a real church.

These drops are just over the past 7 years; looking further back, in 1948, nearly 70% of Christians described themselves as “Protestants” (including both mainline and Evangelicals;) today, that’s dropped to 38%. (I think Black Protestant churches and the Mormons are doing fine, however.)

I don’t want to get into the details of the changing Christian landscape, because that’s way too much to cover in the tail end of a post, but the pattern looks very similar, especially the precipitous drop in the Catholics and Mainline Protestants (the Christian moderates and liberals.) Evangelical Protestants don’t have the birth rates of Orthodox Jews, otherwise they’d probably be doing a little better.

Moldbug proposed that Reform Judaism is Judaism infected with the Progressive virus, where Progressivism itself is a viral form of Mainline Protestant (ie Puritan) Christianity that has shed its specifically theistic aspects in order to compete in our officially a-religious political sphere.

But how much could just be convergent memetic evolution, given an identical meme-vironment?

disgust vs. aggression vs. fertility (part 4 of a series)

(See also: Part 1, Yes, Women Think Male Sexuality is Disgusting; Part 2, Is disgust Real? and Part 3, Disney Explains Disgust.)

So I made some graphs:

Log. graph of homicide rates vs. fertility rates
Log. graph of homicide rates vs. fertility rates
Graph of homicide rates vs fertility rates (data from the Wikipedia)
Graph of homicide rates vs fertility rates (data from the Wikipedia)

Take your pick. They’re the same graph, except the top graph has the homicide rate on a log scale and the bottom on a linear scale, because Honduras’s homicide rate is kind of off the charts.

I couldn’t fit all of the labels onto the graphs, but since most of the countries group by region, you can still figure out roughly where most of them go. The lower left hand corner, low fertility and low homicide, is filled with dots from East Asia and Western Europe. The central-middle-bottom section, of moderate birthrates and below-average homicide rates, has the Muslim countries. The far right–high fertility and medium violence–is mostly African. (Note that Angola and Gambia’s labels have been footnoted at the bottom of the graph.) And the upper left–high violence but moderate fertility–is Latin America. (The high homicide rates are one of the reasons I oppose unfettered Latin American immigration.)

While there is a positive relationship between violence and fertility, this is clearly not the whole story. Just eyeballing the log graph, it looks like a curved line would fit the data better than a straight line, but that’d require polynomial or quadratic regressions and we don’t really need to get into that much detail.

Rather, I suspect that just considering cleanliness explains the graphs: cleaner people are more easily disgusted by other people, and so have fewer children than their aggression levels would predict.

I haven’t found great data on overall “cleanliness” or “disgust rates,” but it appears that Latin Americans are some of the world’s cleanest people:

France, I am looking at you.
From the Atlantic, “How Often People in Various Countries Shower

Brazilians shower nearly 12 times a week, and Mexicans wash their hair more than anyone else.

By contrast, the French and Russians are positively disgusting. (I’m giving India and China a pass here due to limited running water in their countries.)

Here’s another graph, showing similar numbers:

euromonitor

My personal experience with East Asians (Japanese, Taiwanese, etc.,) also suggests that they are cleaner overall than Americans. These countries appear to have been hit with a double-whammy–very clean and low aggression–driving down the interest in sex so far that 60% of girls aged 16-19 claim to be uninterested in sex or even despise it, and even 40-50% of married people haven’t had sex in the past month. They’ve even got a phrase for it, “sex disgust syndrome.”

I don’t find Japanese fertility rates concerning, just because Japan really does need fewer people and the sex-inclined Japanese will quickly replace the non-sex inclined ones, so the issue will work itself out naturally. (And at any rate, I am not really in any position to go telling the Japanese what to do with their own society.)

In our own society, though, I am concerned that decreased monogamy (more “hooking up” via apps like Tinder and Grindr, etc.) is leading to more, not less female concern about male sexual aggression, with all sorts of unfortunate side effects.

And they ought to.

So, I’m going to let you in on a little not-so-secret: childbirth is horrendously painful. Don’t believe those bastards with their natural birth hoo-ha. There is nothing magical or wonderful about childbirth. You bleed copiously, you can barely walk for the next two weeks, and before modern medicine, you stood a good chance of dying in the process.

The US’s homicide rate is 4.7 deaths per 100,000 people per year. The UK’s is 1. Japan’s is 0.3. (Source.)

The “developed nations” have a maternal mortality rate of 16 women per 100,000 births. (Source.) (Note that one woman may give birth to more than one child in her lifetime.)

The “developing nations” have a maternal mortality rate of 230 per 100,000 births (and a much higher number of children per woman,) and some countries have maternal mortality rates around 1,000 per 100,000 births. If the average woman in these countries has 5-7 children, that works out to 5-7% of women dying in childbirth. (Though not every year.)

In other words, in the state of nature, childbirth is kind of like being stuck in the middle of WWII.

 

Let’s consider the male side of things. Given enough available females, a male could, hypothetically, sire one child every night for 30 years, resulting in 10,957 children, plus or minus a couple depending on the leap years. We’ll call 11,000 our “hypothetical male maximum.”

The man stands approximately zero chance of dying in the process of siring children, does not endure pregnancy or childbirth, and even if he depends on someone else to do all of the childcare for him, he still has a reasonable chance at his offspring making it to maturity. (After all, Genghis Khan didn’t get to be the most evolutionarily successful man in recent history by raising all of his bastards.)

In other words, for men, there is basically zero cost to impregnating a woman (other than, obviously, finding one.) Even under harsh economic/environmental conditions, every additional woman a man mates with is an additional chance at offspring. The only limiting factor is how many women he can convince to mate with him.

A woman, by contrast, can produce at max only about 20 children (9 months gestation + 6 months nursing / 25 years fertility). (State of nature does not have baby formula.) She needs a maximum of 20 mates, and can make do with <1 if she has to share.

Where the male number of potential offspring is practically limitless, by human standards, the female is decidedly limited. Which means that women must be picky. A male who has sex once with someone kind of meh is not seriously limiting his ability to have tons of awesome children. A woman who has sex with a guy who’s kind of meh is potentially wasting one of her very limited chances of having children on a loser.

Note: I am not claiming that 11,000 is a realistic number. Obviously even Genghis Khan himself probably didn’t have 11,000 children. The point is that male and female reproduction are vastly different, creating very different incentives.

The average male has approximately zero to lose and all the offspring to gain from a random fling, and thus is mentally ready to consider the majority of women as potential mates. If some of those women happen to not be particularly attractive, well, it’s no big loss.

Women, by contrast, endure high-risk pregnancies and births, for a very limited set of children. They therefore cannot risk having children with inferior males.

So it is in the male’s interest to mate with everyone in sight, but in a woman’s interests to eliminate the vast, vast majority of potential mates, winnowing her selection down to the best 1-4.

Which means that all other potential suitors, whether they’re 14 men in a small hunter-gatherer band or 4 million men in Tokyo, are sexually useless.

In fact, they’re less than useless: they’re a threat. Because it takes only one act of violence for one of those men to get another potential offspring, and for a woman to lose one of hers.

The difference between optimal male and optimal female strategies leads to conflict–not just between men and women, but also between men and men. If one man mates with 550 to 11,000 women, (11,000/20 children per woman = 550), that implies that 549 to 10,999 men are not mating with those women. And those men are going to be pretty pissed.

Monogamy is one of the more elegant solutions to this issue. The relative guarantee of one mate per person reduces conflict and increases parental investment in the children. But monogamy requires fidelity–reducing female interest in the sexual desires of the majority of men even further.

Disgust in the face of unnecessary male sexual attention helps keep women loyal to their husbands and protects their long-term evolutionary interests, even if people express it in really annoying ways.

The Candy Crush Career Track

Candy Crush, Bejeweled, Farmville, and many other games are exceedingly dumb ways to pass your time–and yet, chances are you’ve played some version of them anyway. People have, collectively, spent millions of potentially-productive hours on such games. Even more amazingly, people have spent millions of dollars in actual money on these games.

These games work because they’re addictive. Click the screen a few times, and corn appears! Wow! So you click the screen again, hoping more corn will appear. But as you “progress” through the game, each level becomes harder, takes longer, or requires more clicks. Next thing you know, you’re pulling out your phone at family functions to check on your fake corn instead of socializing with your cousins, or getting mugged on the subway because you were too busy swiping candies to pay attention to your surroundings.

Our career tracks have become far too similar.

I had the luck to catch up with a friend recently during a rare moment of down time. Way back in highschool, she decided to dedicate her life to one of those careers that shows a true commitment to helping others. Her adulthood, so far: 4 years of college; 4 years of grad school; 4 years of training; 2 years in a specialization program. By the time she has any hope of even being geographically settled instead of moving every few years, assuming she can get a job that will let her settle, she’ll be in her mid to late 30s. By the time she’s paid off her education debt, she’ll be in her 50s. Whether she wants kids or not, the question is practically moot.

It’s like the Farmville of real life, only instead of crops, you harvest degrees and grants and papers and fellowships.

Why pursue such a track? Yes, obviously, because she’s passionately committed to helping others, which is what she does. But also because our system requires and rewards such behavior.

There is absolutely no damn reason a JD or MD requires 4 years of college in addition to the programs themselves. There is no damn reason not to expedite a new doctor or lawyer or scientist or pretty much anyone else’s path to geographic and income stability.

When we ask why smart people don’t have more children, a big reason is that smart people are up to their eyeballs in debt, working 12 (or 24!) hour days, and constantly moving in hopes of finally getting enough points on their resumes to score a permanent job.

Fuck, people struggle just to get volunteer jobs.

Meanwhile, compare our friend to an Amish farmer. The work is hard. Back-breaking, sweaty, sometimes disgusting. If you’re unlucky, you could get trampled by a cow or something.

But there are no degrees. You don’t have to go to school to learn how to milk a cow and plow a field; your parents taught you that. There’s very little in the way of career advancement. You’ve been doing farm labor since you were four or so, and you’re likely to continue doing it until you die. You know you’ll probably have a job next year, how much money your crops will bring in, and if you need a new barn, your family will probably pitch in and help you out.

And the Amish have a lot of children. According to the Wikipedia, there were 5,000 Amish in 1920, and there were 290,000 Amish in 2014–and that’s not counting all of the ex-Amish who’ve left the faith over the years.

The same is true for people who aren’t Amish, but who face similarly limited career opportunities. If you can’t advance, you focus your energies elsewhere. If your phone dies because you forgot to charge it, you might be forced to actually interact with the people around you or read a goddamn book for a change.

I like having doctors. I like scientists. I can even stomach the thought of having some lawyers for certain purposes, like helping people fill out their wills. But we have to expedite the process.

America and the Long Term

If there is some general effect of latitude on IQ, then I would not expect America to look, long-term, like Britain or France. Indeed, I’d expect about half of the US to eventually look like North Africa, and the upper half of the US to look more like Spain, Italy, and Turkey.

The US has historically been a land of great abundance–a land where a small founding population like the Amish might grow from 5,000 people in 1920 to over 290,000 people today.

One of the side effects of abundance has been lower infant mortality; indeed, one of the side effects of modernity has been low infant mortality.

In the Middle Ages, a foundling’s chances of surviving their first year were down around 10%. What did orphanages do without formula? (Goat’s milk, I suspect.) Disease was rampant. Land was dear. Even for the well-off, child mortality was high.

My great-great grandparents lost 6 or 7 children within their first week of life.

Things were pretty harsh. An infant mortality rate of 50% was not uncommon.

American abundance, warm climate, industrialization, and modern medicine/hygiene have all worked together to ensure that far more children survive–even those abandoned by one or more parents. (As someone who would have died 3 or 4 times over in infancy without modern medicine, I am not without some personal appreciation for this fact.)

I recently read an interesting post that I can’t find now that basically posited the theory that all of these extra surviving people running around are depressing the average IQ because they have little sub-optimal bits of genetic code that previously would have gotten them weeded out. There’s a decently strong correlation between intelligence and athleticism–not necessarily at the high end of intelligence, but it does appear at the high end of athleticism. Good athletes are smarter than bad athletes. Smart people, Hawking aside, are generally pretty healthy. For that matter, there are strikingly few fat people at the nation’s top universities. So it is not unreasonable to suspect that a few deleterious mutations that result in some wonky side effects in your kidneys or intestines might also cause some wonky side effects in your brain, which could make you dumber or just really fond of stuffed animals or something.

Okay, but this post is not actually about the theory that low infant mortality is turning us all into furries.

My theory is that America + Modernity => more children of single mothers surviving => long therm changes in marriage/divorce rates => significant long term changes in the structure of society.

Historically, if we go a little further south to Sub-Saharan Africa, monogamy has not been a big thing. Why? Because the climate is generous enough that people don’t have to store up a ton of food for the winter, and women can do most of the food production to feed their children by themselves, or with the help of their extended kin networks. In these places, polygyny is far more common, since men do not need to bear the burden of providing for their own children.

As we head north, the winters get colder and the agricultural labor more intensive, and so the theory goes that women in the north could not provide for their children by themselves. And so Fantine, unwed, dies attempting to provide for her little Cosette, who would have died as well were it not for the ways of novels. The survivors were the men and women who managed to eek out a living together–married, basically monogamous.

But take away the dead Cosettes and Olivers–let them survive in more than just books–and what do we have? Children who, sooner or later, take after their parents. And even if one parent was faithful ’till death, the other certainly wasn’t.

Without any selective pressure on monogamy, monogamy evaporates. So now you can get a guy who has 34 children by 17 different women, and all of the children survive.

Meanwhile, neurotic types who want to make sure they have all of their career and personal ducks all lined up in a row “just can’t afford” a kid until they’re 38, have one if they’re lucky, and then call it quits.

Guess who inherits the future?

Those who show up, that’s who.

I suspect that the effects of low infant mortality have been accumulating for quite a while. Evolution can happen quite quickly if you radically change your selective parameters. For example, if you suddenly start killing white moths instead of grey ones, the moth population will get noticeably darker right after you kill the moths. Future generations of moths will have far fewer white moths. If you then top killing the white moths, white moths will again begin to proliferate. If white moth start having even more babies than grey moths, soon you will have an awful lot of white moths.

Long term, I expect one of the effects of abandoned children surviving is that the gene pool ends up with a lot more people who lack a genetic inclination toward monogamy. At first, these people will just be publicly shamed and life will continue looking relatively normal. But eventually, we should get to a tipping point where we have enough non-monogamous people that they begin advocating as a block and demanding divorce, public acceptance of non-marital sex, etc.

Another effect I would expect is a general “masculinization” of the women. Women who have to fend for themselves and raise their own children without help from their husband have no practical use for femininity, and the more masculine among them will be more likely to thrive. Wilting, feminine flowers will fade away, replaced by tough dames who “need a man like a fish needs a bicycle.”

Only time will tell if the future will belong to the Amish and the Duggers, or to Jay Williams’ progeny.
