The evolution of fraud

Much of evolutionary literature focuses on the straightforward relationship between predator and prey, or on competition between members of the same species for limited resources, mates, etc.

But today we’re going to focus on fraud.

Milk Snake

Coral Snake
Coral Snake

Red touch yellow, kill a fellow. Red touch black, friend to Jack.

The Coral snake is deadly poisonous. (Or venomous, as they say.) The Milk snake is harmless, but by mimicking the coral’s red, black, and yellow bands, it tricks potential predators into believing that it, too, will kill them.

Eastern_Phoebe-nest-Brown-headed-Cowbird-eggThe milk snake is a fraud, benefiting from the coral’s venom without producing any of its own.

Nature has many frauds, from the famously brood-parasitic Cuckoos to the nightmare-fuel snail eyestalk-infecting flatworms, to the fascinating mimic octopus, who can change the colors and patterns on its skin in the blink of an eye.

But just as predator and prey evolve in tandem, the prey developing new strategies to outwit predators, and predators in turn developing new strategies to defeat the prey’s new strategies. So also with fraud; animals who detect frauds out-compete those who are successfully deceived.

Complex human systems depend enormously on trust–and thus are prime breeding grounds for fraud.

Let’s take the job market. Employers want to hire the best employees possible (at the lowest possible prices, of course.) So employers do their best to (efficiently) screen potential candidates for work-related qualities like diligence, honesty, intelligence, and competency.

Employees want to eat. Diligence, honesty, years spent learning how to do a particular job, etc., are not valued because they help the company, but because they result in eating (and, if you’re lucky, reproduction.)

When there are far more employees competing against each other for jobs than there are openings, not only do employers have a chance to ratchet up the qualifications they demand in applicants, they pretty much have to. No employer trying to fill a single position has time to read 10,000 resumes, nor would it be in their interest to do so. So employers come up with requirements–often totally arbitrary–to automatically cut down the number of applications.

“Must have 3-5 years work experience” = people with 6 years of experience automatically rejected.

“Must be currently employed with no gaps in resume” = no one who took time off to have children. (This is one of the reasons birthrates are so low.)

“Must have X degree” = person with 15 years experience in the field but no degree automatically rejected.

The result, of course, is that prospective employees begin lying, cheating, or finding other deceptive ways to trick employers into reading their resumes. Workers with 6 years of experience put down 5. Workers with 2 record 3. People who can’t get into American medical schools attend Caribbean ones. “Brought donuts to the meeting” is inflated to “facilitated cross-discipline network conversation.” Whites who believe employers are practicing AA tickybox “black” on their applications. And as more and more jobs that formerly required nothing more than graduating college start requiring college degrees, more and more colleges start offering bullshit degrees so that everyone can get one.

The higher the competition and more arbitrary the rules, the higher the incentives for cheating.

The problem is particularly bad (or at least blatant) in many developing countries, eg, The Mystery of India’s Deadly Exam Scam:

It began with a test-fixing scandal so massive that it led to 2,000 arrests, including top politicians, academics and doctors. Then suspects started turning up dead. What is the truth behind the Vyapam scam that has gripped India? …

For at least five years, thousands of young men and women had paid bribes worth millions of pounds in total to a network of fixers and political operatives to rig the official examinations run by the Madhya Pradesh Vyavsayik Pariksha Mandal – known as Vyapam – a state body that conducted standardised tests for thousands of highly coveted government jobs and admissions to state-run medical colleges. When the scandal first came to light in 2013, it threatened to paralyse the entire machinery of the state administration: thousands of jobs appeared to have been obtained by fraudulent means, medical schools were tainted by the spectre of corrupt admissions, and dozens of officials were implicated in helping friends and relatives to cheat the exams. …

The list of top state officials placed under arrest reads like the telephone directory of the Madhya Pradesh secretariat. The most senior minister in the state government, Laxmikant Sharma – who had held the health, education and mining portfolios – was jailed, and remains in custody, along with his former aide, Sudhir Sharma, a former schoolteacher who parlayed his political connections into a vast mining fortune.

One of the things I find amusing (and, occasionally, frustrating) about Americans is that many of us are still so trusting. What we call “corruption”–what we imagine as an infection in an otherwise healthy entity–is the completely normal way of doing business throughout most of the world. (I still run into people who are surprised to discover that there are a lot of scams being run out of Nigeria. Nigerian scammers? Really? You don’t say.)

It’s good to get out of your bubble once in a while. Go hang out on international forums with people from the third world, and listen in on some of the conversations between Indians and Pakistanis or Indians and Chinese. Chinese and Indians constantly accuse each other’s countries of engaging in massive educational cheating.

Maybe they know something we don’t.

People want jobs because jobs mean eating; a good job means good eating, ergo every family worth its salt wants their children to get good jobs. But in a nation with 1.2 billion people and only a few good jobs, competition is ferocious:

In 2013, the year the scam was first revealed, two million young people in Madhya Pradesh – a state the size of Poland, with a population greater than the UK – sat for 27 different examinations conducted by Vyapam. Many of these exams are intensely competitive. In 2013, the prestigious Pre-Medical Test (PMT), which determines admission to medical school, had 40,086 applicants competing for just 1,659 seats; the unfortunately named Drug Inspector Recruitment Test (DIRT), had 9,982 candidates striving for 16 vacancies in the state department of public health.

For most applicants, the likelihood of attaining even low-ranking government jobs, with their promise of long-term employment and state pensions, is incredibly remote. In 2013, almost 450,000 young men and women took the exam to become one of the 7,276 police constables recruited that year – a post with a starting salary of 9,300 rupees (£91) per month. Another 270,000 appeared for the recruitment examination to fill slightly more than 2,000 positions at the lowest rank in the state forest service.

Since no one wants to spend their life picking up trash or doing back-breaking manual labor in the hot sun, the obvious solution is to cheat:

The impersonators led the police to Jagdish Sagar, a crooked Indore doctor who had set up a lucrative business that charged up to 200,000 rupees (£2,000) to arrange for intelligent but financially needy medical students to sit examinations on behalf of applicants who could afford to pay.

The families of dumb kids pay for smart kids to take tests for them.

In 2009, police claim, Sagar and Mohindra [Vypam’s systems analyst/data entry guy] had a meeting in Sagar’s car in Bhopal’s New Market bazaar, where the doctor made an unusual proposition: he would give Mohindra the application forms of groups of test-takers, and Mohindra would alter their “roll numbers” to ensure they were seated together so they could cheat from each other. According to Mohindra’s statement to the police, Sagar “offered to pay me 25,000 rupees (£250) for each roll number I changed.”

This came to be known as the “engine-bogie” system. The “engine” would be one of Sagar’s impostors – a bright student from a medical college, taking the exam on behalf of a paying customer – who would also pull along the lower-paying clients sitting next to him by supplying them with answers. … From 2009 to 2013, the police claim, Mohindra tampered with seating assignment for at least 737 of Sagar’s clients taking the state medical exam. …

Mohinda also began just straight-up filling in the bubbles and altering exam scores in the computer for rich kids whose parents had paid him off.

Over the course of only two years, police allege, Mohindra and Trivedi conspired to fix the results of 13 different examinations – for doctors, food inspectors, transport constables, police constables and police sub-inspectors, two different kinds of school teachers, dairy supply officers and forest guards – which had been taken by a total of 3.2 million students.

Remember this if you ever travel to India.

But merely uncovering the scam does not make it go away; witnesses begin dying:

In July 2014, the dean of a medical college in Jabalpur, Madhya Pradesh, Dr SK Sakalle – who was not implicated in the scandal, but had reportedly investigated fraudulent medical admissions and expelled students accused of obtaining their seats by cheating – was found burned to death on the front lawn of his own home. …

In an interview with the Hindustan Times earlier this year, a policeman, whose own son was accused in the scam and died in a road accident, advanced an unlikely yet tantalising theory. He argued that the Vyapam taskforce – under pressure to conduct a credible probe that nevertheless absolved top government officials – had falsely named suspects who were already deceased in order to shield the real culprits.

A competing theory, voiced by journalists covering the scandal in Bhopal, proposes that it will be all but impossible to determine whether the deaths are connected to Vyapam, because the families of many of the dead refuse to admit that their children paid money to cheat on their exams – for fear that the police might arrest the bereaved parents as well.

For India’s poor (and middle class,) scamming is a dammed if you do, dammed if you don’t affair:

“My brother was arrested four months ago for paying someone to ensure he cleared the police constable exam in 2012,” the man told me. “Some people in our village said, ‘This is Madhya Pradesh, nothing happens without money.’ My brother sold his land and paid them 600,000 rupees.”

In August that year, he was one of 403,253 people who appeared for the recruitment test to become a police constable. … Four months after his marriage, his name popped up in the scam, he lost his job and he was hauled off to prison.

“So now my brother has a wife and his first child, but no job, no land, no money, no prospects and a court case to fight,” the man said. “You can write your story, but write that this is a state of 75 million corrupt people, where there is nothing in the villages and if a man comes to the city in search of an honest day’s work, the politicians and their touts demand money and then throw him into jail for paying.”

Pay them their wages each day before sunset, because they are poor and are counting on it. Otherwise they may cry to the Lord against you, and you will be guilty of sin. -- Deuteronomy 24:15
“Pay them their wages each day before sunset, because they are poor and are counting on it. Otherwise they may cry to the Lord against you, and you will be guilty of sin.” — Deuteronomy 24:15

India is not the only place with such scandals:

China Catches 2,440 Students Cheating in High-Tech Scam

Behind Fake Degrees From Pakistan, a Maze of Deceit

2012 Harvard Cheating Scandal

Or, you know, pretty much the entire US economy, especially finance, insurance, and real estate.

I would like to note that in many of these cases, the little guys in the scam, while arguably acting dishonestly and cheating against their neighbors, are basically well-intentioned people who don’t see any other options besides bribing their way into jobs. In the end, these guys often get screwed (or end up dead.)

It’s the people who are taking the bribes and fixing the tests and creating bullshit degrees and profiting off people’s houses burning down who are getting rich off everyone else and ensuring that cheating is the only way to get ahead.

These people are parasites.

Parasitism increases complexity in the host organism, which increases complexity in the parasite in turn:

With selection, evolution can also produce more complex organisms. Complexity often arises in the co-evolution of hosts and pathogens,[7] with each side developing ever more sophisticated adaptations, such as the immune system and the many techniques pathogens have developed to evade it. For example, the parasite Trypanosoma brucei, which causes sleeping sickness, has evolved so many copies of its major surface antigen that about 10% of its genome is devoted to different versions of this one gene. This tremendous complexity allows the parasite to constantly change its surface and thus evade the immune system through antigenic variation.[8]

Animals detect and expel parasites; parasites adapt to avoid detection.

So, too, with human scams.

We tend to increase complexity by adding paperwork.

A few people cheat on their taxes, so the IRS begins randomly auditing people to make sure everyone is complying. A few people refuse to hire African Americans, so companies must keep records on the ethnic/racial identities of everyone they interview for a job. An apartment complex fears it could get sued if a car hits a bicyclist in the parking lot, so it forbids all of the children there from riding their bikes. A college gets sued after a mentally ill student commits suicide on campus, so the college starts expelling all mentally ill students.

Now, while I appreciate certain kinds of complexity (like the sort that results in me having a computer to write on and an internet to post on,) the variety that arises due to a constant war between parasites and prey doesn’t seem to have much in the way of useful side effects. Perhaps I am missing something, but it does not seems like increasing layers of oversight and bureaucracy in an attempt to cut down cheating makes the world any better–rather the opposite, in fact.

Interestingly, fevers are not diseases nor even directly caused by disease, but by your own immune system responding to disease. By increasing your internal temperature, your body aims to kill off the infection or at least make things too inhospitable for it to breed. Fevers (within a moderate range) are your friends.

They are still unpleasant and have a seriously negative effect on your ability to get anything else done.

An ill patient can do little more than lie in bed and hope for recovery; a sick society does nothing but paperwork.

Certainly the correct response to parasitism is to root it out–paperwork, fever, and all. But the long-term response should focus on restructuring institutions so they don’t become infected in the first place.

In human systems, interdependence in close-knit communities is probably the most reliable guard against fraud. You are unlikely to prosper by cheating your brother (genetically, after all, his success is also half your success,) and people who interact with you often will notice if you do not treat them fairly.

Tribal societies have plenty of problems, but at least you know everyone you’re dealing with.

Modern society, by contrast, forces people to interact with and dependent upon thousands of people they don’t know, many they’ve met only once and far more they’ve never met at all. When I sit down to dinner, I must simply trust that the food I bought at the grocery store is clean, healthy, and unadultarated; that no one has contaminated the milk, shoved downer cows into the chute, or failed to properly wash the tomatoes. When I drive I depend on other drivers to not be drunk or impaired, and upon the city to properly maintain the roads and direct traffic. When I apply for jobs I hope employers will actually read my resume and not just hire the boss’s nephew; when I go for a walk in the park, I hope that no one will mug me.

With so many anonymous or near-anonymous interactions, it is very easy for people to defraud others and then slip away, never to be seen again. A mugger melts into a crowd; the neighbor whose dog shat all over your yard moves and disappears. Twitter mobs strike out of the blue and then disperse.

So how do we get, successfully, from tight-knit tribes to million+ people societies with open markets?

How do modern countries exist at all?

I suspect that religion–Christianity in the West, probably others elsewhere–has played a major role in encouraging everyone to cooperate with their neighbors by threatening them with eternal damnation if they don’t.

To return to Deuteronomy 24:

Do not take a pair of millstones—not even the upper one—as security for a debt, because that would be taking a person’s livelihood as security.

If someone is caught kidnapping a fellow Israelite and treating or selling them as a slave, the kidnapper must die. You must purge the evil from among you. …

10 When you make a loan of any kind to your neighbor, do not go into their house to get what is offered to you as a pledge. 11 Stay outside and let the neighbor to whom you are making the loan bring the pledge out to you. 12 If the neighbor is poor, do not go to sleep with their pledge in your possession. 13 Return their cloak by sunset so that your neighbor may sleep in it. Then they will thank you, and it will be regarded as a righteous act in the sight of the Lord your God.

14 Do not take advantage of a hired worker who is poor and needy, whether that worker is a fellow Israelite or a foreigner residing in one of your towns. 15 Pay them their wages each day before sunset, because they are poor and are counting on it. Otherwise they may cry to the Lord against you, and you will be guilty of sin. …

17 Do not deprive the foreigner or the fatherless of justice, or take the cloak of the widow as a pledge. 18 Remember that you were slaves in Egypt and the Lord your God redeemed you from there. That is why I command you to do this.

To be fair, we have to credit Judaism for Deuteronomy.

Here we have organized religion attempting to bridge the gap between tribalism and universal morality. Enslaving one of your own is an offense punishable by death, but there is no command to rescue the enslaved of other nations. You must treat your own employees well, whether they come from your own tribe or other tribes.

In tribal societies, justice is run through the tribe. People with no families or clans–like orphans and foreigners–therefore cannot access the normal routes to justice.

As Peter Frost notes of the German societies of the early Dark Ages:

The new barbarian rulers also disliked the death penalty, but for different reasons. There was a strong feeling that every adult male had a right to use violence and to kill, if need be. This right was of course reciprocal. If you killed a man, his death could be avenged by his brothers and other male kinsmen. The prospect of a vendetta thus created a ‘balance of terror’ that kept violence within limits. So, initially, the barbarians allowed capital punishment only for treason, desertion, and cowardice in combat (Carbasse, 2011, p. 35). [bold mine]

Frost quotes:

[The Salic Law] is a pact (pactus) “concluded between the Franks and their chiefs,” for the specific purpose of ensuring peace among the people by “cutting short the development of brawls.” This term evidently means private acts of vengeance, the traditional vendettas that went on from generation to generation. In place of the vengeance henceforth forbidden, the law obliged the guilty party to pay the victim (or, in the case of murder, his family) compensation. This was an indemnity whose amount was very precisely set by the law, which described with much detail all of the possible damages, this being to avoid any discussion between the parties and make [murder] settlements as rapid, easy, and peaceful as possible. […] This amount was called the wergild, the “price of a man.” The victim’s family could not refuse the wergild, and once it was paid, the family had to be satisfied. They no longer had the right to avenge themselves (Carbasse, 2011, pp. 33-34).

(The Wikipedia notes that, “The same concept outside Germanic culture is known as blood money. Words include ericfine in Ireland, galanas in Wales, veriraha in Finnish, vira (“вира“) in Russia and główszczyzna in Poland. In the Arab world, the very similar institution of diyya is maintained into the present day.”)

Frost continues:

This situation began to change in the 12th century. One reason was that the State had become stronger. But there also had been an ideological change. The State no longer saw itself as an honest broker for violent disputes that did not challenge its existence. Jurists were now arguing that the king must punish the wicked to ensure that the good may live in peace.

In a tribal system, a victim with no family has no one to bring a suit on their behalf, if they are murdered, there is no one to pay weregild to. This leaves orphans and “foreigners” without any access to justice.

Thus Deuteronomy’s command not to mistreat them (or widows.) They aren’t protected under tribal law, but they are under Yahweh’s.

The threat of divine punishment (and promise of rewards for good behavior,) may have encouraged early Christians to cooperate with strangers. People who would cheat others now have both their own consciences and the moral standards of their Christian neighbors to answer to. The ability to do business with people outside of one’s own family or clan without constant fear of getting ripped off is a necessary prerequisite for the development of free markets, modern economies, and million+ nations. (In short, universalism.)

In the absence of universalist societies that effectively discourage cheating, groups that protect their own will out-compete groups that do not. The Amish, for example, have grown from 5,000 to 300,000 people over the past century (despite significant numbers of Amish children choosing to leave the society every generation.)

(By contrast, my own family has largely failed to reproduce itself–my cousins are all childless, and I have no second cousins.)

The Amish avoid outsiders, keeping their wealth within their own communities. This probably also allows them to steer clear of cheaters and scammers (unlike everyone who lost money in the 2008 housing crash or the 2001 stock market crash.) As insular groups go, the Amish don’t seem too bad–I haven’t heard any reports of them stealing people’s chickens or scamming elderly widows out of their life’s savings.

America and the Long Term

1280px-World_map_2004_CIA_large_1.7m_whitespace_removed

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.

Memetic Separatism => Ethnicity (part 2 of the meme posts)

So, as I was saying, before I had to run off…

Meme Mitochondrias reproduce primarily by hitching a ride on human reproduction. Success, therefore, optimizes them to encourage human reproduction.
Meme mitochondrias do not optimize for pleasure.

Meme Viruses reproduce by convincing people to adopt them.
Success, therefore, optimizes them to encourage pleasure or beneficial habits.
Meme viruses do not optimize for human reproduction.

Memes can switch forms–Christianity was originally spread as a virus, but quickly became mitochondrial. Today, with church membership waning across the US (and the Rest of the West,) American churches are campaigning actively for more Hispanic members via immigration reform–failure of mitochondrial mode leads to activation of viral mode.

Mormonism has spread particularly well because it employs both modes.

One of the conclusions I draw from this is that mitochondrial memes will tend to look rather unpleasant to people. Few people will adopt these memes if exposed to them after childhood, and many people raised with these memes will “defect”.

EG, being Amish. The Amish community has had significant out-migration over the years–about 25% each generation, from what I’ve heard–but almost zero in-migration. Being Amish simply isn’t attractive to terribly many non-Amish. (By contrast, being an American is attractive to millions of non-Americans.)

The Amish continue to exist because they have tons of children–enough children to replace the defectors (and then some.) To put it in numbers:

If the average Amish woman had 2 children, and 25% of Amish children defected during Rumspringa, the effective TFR would be only 1.5 children per woman, and the population would quickly shrink.
If the average Amish woman has 4 children, and 25% defect, the effective TFR remains 3 children per woman, and the population still grows.

We can call this process, “boiling off”. Over time, the Amish who are most inclined toward the outside world are most likely to boil off, while the most Amishy-Amish are most likely to stay, leading to an ever-more distinctive Amish population.

Genetically, the Amish and non-Amish Pennsylvanians are quite distinct, despite 25% or so of Amish out-migrating each generation.

(I have recently seen people commenting upon a quote attributed to Ben Franklin that complained about the Germans in Pennsylvania, as proof that people have historically been bigoted and over-reacted to new immigrants. I think it entirely possible, though, that Franklin was basically correct–having a bunch of people around who set up ethnically-exclusive communities and are explicitly opposed to interacting with the broader culture could actually be problematic.)

We would also expect the dominant narrative outside of any particular mitochondrial meme complex (ie ethnic culture) to be heavily influenced by the accounts of deserters–people who did not like that society. By contrast, people within an ethnic culture probably tend to like it (they tend to be the people who did not defect, after all.) Non-Amish find the Amish lifestyle boring and exhausting, but the Amish probably actually like it.

A similar case study is Judaism. Memetically speaking, Judaism is strongly mitochondrial. (It once spawned a viral offspring, called Christianity. This was very bad, as the newly infected could not recognize carriers of the parent meme as members of their viral community, and so kept trying to infect or exterminate them.)

There is an axiom in regular evolutionary science that two closely related species (or sub-species) cannot occupy the same environmental niche. Either one group will out-compete the other, thus replacing it, or the two groups will merge.

Is there no hope for an equilibrium solution, with neither replacement nor merger?

If the two groups have different behaviors, then sooner or later, one group will get the upper hand (or claw, paw, wing, or fin,) and out-compete the other, (or their behavior will steer them into a different environmental niche.) If the two groups have identical behaviors, then they will not be able to distinguish between each other as mates and will merge. (If they are genetically incapable of mating, then they will also be genetically incapable of performing the same behaviors, and we are back to out-competing.)

Among humans, people who possess similar values and behaviors (that is, culture, that is, memes,) tend to mate with each other, leading to genetically distinct groups of people.

In the absence of a physical barrier (like being on isolated island for a few thousand years,) memes create ethnicity. A coherent meme-system is a culture.
Cultures contain both mitochondria and virus memes, eg., Americans value democracy (virus) and monogamous marriages (mitochondrial).

Back to the Jews. The Jews have managed to exist for thousands of years (despite some pretty big obstacles,) and are genetically distinct from their neighbors, despite tremendous out-migration over the years. The Ashkenazi, for example, have very little German DNA, despite having lived in Germany for, what, about 800 years? (Rather, they’re about half Italian, mostly along their maternal lines, surprising no one who has ever observed immigrants.) Today, out-marriage among American Jews is estimated around 50%.

Looking at the behavior of the various major Jewish denominations in the US, the haredi Jews operate much like the Amish–they have a bunch of children, about 25% of whom defect to other Jewish denominations, and receive very few formerly-Conservative or Reform Jews into their ranks. Being haredi just isn’t attractive to people who aren’t born into it–it’s mitochondrial. However, the ranks of haredi Jews are still growing, due to their extremely high fertility rates.

Reform and Conservative Judaism, by contrast, receive continual infusions of new members from ex-haredim. However, their fertility rates are very low (by contrast.) They are dependent on “converts” in order to continue to exist. Therefore, they are viral, not mitochondrial.

The endpoint of this progression is obvious: Reform, Reconstructionist, and Atheist Jews who marry non-Jews and whose children and grandchildren cease being Jewish.

Incidentally, if you want your descendants to be Jewish, you must teach your children mitochondrial Judaism. Virus-Judaism is too similar to non-Judaism to maintain ethno-cultural separatism.

How can this be, if Jews have been so separate over the years?

Before Napoleon invaded the rest of Europe and imposed the aptly named Code Napoleon, Jews and Christians throughout Ashkenazi lands were legally forced into separate communities and professions, eg, the Prague Ghetto. This means they were forced into different niches, and just like birds cracking different nuts developing different beaks, we should expect to see the development of different norms, values, and skills suited to their particular niches (and a quick examination of the professions available in the Ashkenazi niche explains their development of higher IQs than other Europeans.)

Napoleon was defeated, but his Code remained, emancipating the Jews across much of Europe. With the legal restrictions gone, the two groups now occupied–more or less–the same niche. The two groups must either compete, merge, or find new niches.

The rates of out-migration, even in the 1800s in Germany, were apparently tremendous, at least according to the Jewish sources I have read on the matter. (My and my spouses’ DNA attests to this.) Like the Amish, would expect the out-migration to leave behind a remnant population that is less interested in being like the non-Jewish world. In the Ghetto days, a more liberal or atheist Jew would have been forced by circumstances to marry another Jews, probably one more religious than themselves, and their children would have reverted to the norm. More devout Jews would have been likely to marry not as devout as themselves Jews, again returning their children toward the norm.

Without the Ghetto, the less-religious marry out, and the more-religious marry each other, the only folks left. The probable result: a (growing) remnant population of increasingly haredi Jews on the one hand, and an assimilationist group whose meme-virus begins to look increasingly similar to the more secular branches of Christianity, like Unitarian Universalism.

For obvious reasons, the haredim will come to “represent” what Judaism “means” in people’s imaginations, because the assimilationist Jews simply aren’t distinct enough to be viewed as a separate group.

(Unfortunately, I would not be surprised to see American Ashkenazi IQ plummet over the next century toward the American norm, since being haredi selects more for ability to birth lots of children than IQ, and the most intelligent Jews tend to be atheists or something close to it.)

Or to put it another way, once the Ashkenazim and Christians begin occupying the same niche and inter-marrying, they adopt new meme viruses to support their new behavior patterns, and people and their spouses will want to adopt the same viruses so they can have the same behavior. Otherwise, it’s not going to work. If I want to send my kids to Hindu School, and you want to send them to Catholic School, we’re going to have a conflict. If we declare that Jesus is just an avatar of Vishnu, then we have eliminated the conflict. Our ideas (and thus our genes) have merged.

We can also see this working on a broader scale–eg, modern transportation makes it pretty easy for disaffected Texans to move to Massachusetts.

Conservative American culture is more mitochondrial–they have more babies, outsiders find their culture oppressive, and I bet you the children of conservatives are more likely to become liberals than vice versa.

Liberal culture is more viral. Liberals often forgo reproducing entirely, preferring instead to spread their ideas by talking about them. This leads to people referring to liberals as “defectors” or “traitors”. (I would rather conceptualize them as allying, but perhaps that is me being overly optimistic.)

With no credible outside threat to force Americans to unite, liberals would rather unite with other liberals and define themselves in contrast to conservatives than cooperate with (and occasionally marry) conservatives (and vice versa.) (While liberals definitely report more positive views on interracial marriage than conservatives, I should note that the actual statistics on interracial marriage and multi-ethnic households may lean just slightly toward the conservatives–possibly because of class stratification and geography in America making liberals less likely to actually interact with ethnic minorities, and possibly because Conservatives adopt more kids, often internationally.)

Results:
1. Liberal culture assimilates with cultures not traditionally part of the American mainstream, like African American, European, or Asian cultures (eg, liberals are more likely to have adopted the Asian norm of removing their shoes upon entering the house, and are more likely to pride themselves on watching foreign movies.)

2. Conservative culture becomes a remnant, like the Amish or Haredi Jews. And like them, the Conservatives become the cultural “symbol” of what it “means” to be American.

3. Liberals become very uncomfortable with identifying as “American” because it now represents “conservative” to them. I’m pretty sure that liberals who fought in the trenches of WWII self-identified pretty strongly as “American”, and believed that America was a great and glorious country out to make the world a better place by defeating the Nazis and Japanese. Modern American liberals quite frequently report being “ashamed” of being Americans, and cringe (or mock) the sight of a bald eagle alighting on an American flag hoisted aloft by Jesus delivering the Constitution to the Founding Fathers.

Conservatives, meanwhile, wish Liberals would pack up and leave already.

4. Liberalism requires a constant influx of new believers, otherwise “liberal” will shift consistently rightward due to low liberal birthrates. (Conservatives, by contrast, are closer to replacement.) It is therefore perhaps not coincidental that liberals push strongly for the incorporation of new groups of people into the country–people who will probably vote liberal, at least for a while.

There is one complication I have basically been glossing over: genetics influence your meme preferences. People with a genetic propensity toward anger will probably prefer memes that are pro-anger/violence. People with a genetic propensity toward empathy will probably prefer memes that emphasize the importance of empathizing with others. Nice people talk about how much they like Gandhi; jerks appreciate Hitler. People with larger amygdalas have stronger disgust reactions and are more likely to be conservatives and neophobic. People with smaller amygdalas think that eating raw fish sounds like it could be fun, rather than revolting. Some people are more genetically inclined to pick up new ideas, while others are more “immune” to them.

An interesting case of “immunity” is the general Western reaction to Christianity in the past few decades. Westerners are leaving Christianity in droves, (much like Judaism,) but Christianity will likely continue in this country because the new population of Hispanics is much less immune.
