Did Westward Expansion Cause the Civil War?

Mass migrations have probably been among the great selective events of human history. The Ostsiedlung, for example, selected for German citizens who were well-disciplined, hard working, good planners, and probably quick to defend their land holdings from others. Overall, Germans descended from the folks who participated in the Ostsiedlung appear to be more likely to join or vote for far-right political parties, be Neo-Nazis, or otherwise engage in “far right subcultures.”

(Here is a map for you:

NPD = German far-right political party)

In Jayman’s discussion of the Pioneer Hypothesis, he notes:

“The Whites in the U.S. have a much higher TFR than most any European country. As well, Europeans overall are much further to the Left than Americans. I became interested in this when I noted that most of the ethnic groups of Americans—particularly the ones away from urban areas—seem far more to the Right than their brethren in the Old Countries. …

“Particularly interesting is the conservative nature of huge swaths of the Midwest and the Upper Plains/Mountain West. These places, while receiving some settlers ultimately originating from the Anglo-Scottish border regions and other Scotch-Irish (the same people who settled Appalachia), are also suffused with large numbers of other Europeans, such Germans and Scandinavians, people who today aren’t exactly known to be raving right-wingers. …

“Liberals are concentrated in old-colonial states, in places without much space to expand into. The reddest states on the other hand are areas with wide open stretches of land. … We can see what by looking the fertility rates of liberal (and sparsely populated) northern New England. The U.S. states of Maine, Vermont, and New Hampshire have plenty of land and low land values, but aren’t very fecund. … The population in upper New England is largely composed of the original colonial stock; they lost their fast-breeding inklings long ago…”

Jay hypothesizes that the cities produce liberals, ie,

“Liberal-minded people (and by extension, slow-breeders in general, when Eastern Europe and East Asia are also considered) descend from people who have stayed put for generations—or at the very least, never moved into previously empty lands. Under such conditions—which, prior to industrialization was Malthusian—rapid breeders were not favored. Rather efficient competitors—those who maximize their resources before starting a family—were selected for.”

And that the countryside produces conservatives, ie,

“The early colonist came and spread across the land very quickly, easily displacing the earlier inhabitants. … The rapid increase of a population when it moves into an area that it did not previously inhabit sounds like a great opportunity for evolution by natural selection to work its magic.

“When new land is abundant, and “family formation” is relatively easy, which types of individuals are selected for? Yup, those who married young and had lots of children (the fairly harsh and physically demanding nature of the American frontier ensured that paternal investment needed to remain high, such that stable marriage was important). In short, people who are “family oriented” are selected for.”

I propose a complementary hypothesis:

Migration is more appealing to conservatives than to liberals, so major migrations result in conservatives self-sorting into frontier areas, while liberals are left behind.

Further, this sorting event may trigger a “run away” effect: as people find themselves in an environment that seems increasingly liberal (or conservative,) due to all of the conservatives (or liberals) leaving, they shift their own political opinions to better agree with the consensus or perhaps maintain their own self image as more liberal than others, leading the group to shift increasingly liberal (or conservative.)

Notice an inconsistency in Jay’s theory that he himself admits: low fertility in rural Maine, Vermont, and New Hampshire. If open land itself selects for higher fertility, then even a population whose ancestors were liberals ought, over time, to become more fecund. But if the conservatives have simply left these areas for Kansas, leaving the liberals behind, then we might expect to find liberals in Maine and conservatives in Kansas.

Likewise, colonization of the US may have involved the more conservative elements migrating from Europe to the US, leaving behind a more liberal Europe compared to the new colonies. Since this is a post that’s ultimately supposed to be about the Civil War, let’s use slavery as an example issue.

France abolished slavery in its overseas colonies in 1794 (it had been illegal in mainland France since the 1300s,) though this was violently opposed by the colonists and slavery was re-instituted until 1848, (Haiti obviously excepted.)

In 1783, the British began agitating against slavery; by 1799, Britain abolished the enslavement of Scottish coal miners and salters. (An act passed in 1606 had enslaved them.) The slave trade was abolished in 1807, and in 1833, slavery was formally abolished throughout their empire.

Spain, (a major colonizer earlier than Britain or France,) attempted to outlaw slavery in its colonies in 1542, but this was never enforced throughout most of their territory due to colonialist opposition. Slavery was eventually abolished throughout most of Latin America during the 1810-1820s Independence Wars, but it persisted for a few decades more in a few places, and wasn’t abolished until 1873 in Puerto Rico, 1886 in Cuba, and 1888 in Brazil. (Brazil wasn’t a Spanish colony, of course.)

On to the US!

It’s no secret that the bulk New England’s colonists happened to be more liberal than the bulk of the South’s, and by 1804, slavery was illegal throughout the North. This may overstate the North’s position, however, as the anti-slavery laws came only gradually into effect.

While slavery remained legal in the South until 1865 (and who knows how long it would have stayed legal had the North not intervened,) many Southerners had begun voluntarily freeing their slaves. By 1810, Virginia, Maryland, and Delaware had substantial freedman populations, with Delaware in the lead with 75% of their slaves free. Estimates of the total number of free blacks on the eve of the Civil War vary from 488 thousand (or 11% of the total black population of the US,) to 1.5 million (or 34%). (I suspect the discrepancy is due to different definitions of “free.”)

I have heard some speculation that, had the North not intervened, the South would have eventually given up slavery on its own, much like Brazil. Certainly this fits with the generalized pattern across the Western world, but I have no evidence at my disposal to support (or contradict) the idea.

Regardless, I do know that the attitude in the North toward abolitionism changed radically between 1800 and 1860.

In the early 1800s, Northern views on the abolitionists in their midst ranged from “Kind of weird” to “Kill them with fire,” as graphically illustrated by the time white abolitionist William Lloyd Garrison was nearly murdered by an angry mob in Boston, MA:

“In the fall of 1835, a mob of several thousand surrounded the building housing Boston’s anti-slavery offices, where Garrison had agreed to address a meeting of the Boston Female Anti-Slavery Society after the fiery British abolitionist George Thompson was unable to keep his engagement with them. The mayor and police persuaded the women to leave the building, but when the mob learned that Thompson was not within, it began yelling for Garrison with cries for his lynching or tar and feathering. The mayor managed to sneak Garrison and an assistant out a window, but the mob pursued, captured him, tied a rope around his waist, and dragged him through the streets of Boston. The sheriff rescued Garrison from lynching by arresting him and taking him to the Leverett Street Jail for his own protection.” (Wikipedia.)

By the late 1850s, private citizens in the North were raising money to fund John Brown’s eventual bloody raid on Harper’s Ferry; by 1861, the North collectively decided it was worth killing at least 260,000 Southerners (the vast majority of whom did not even own slaves) and sacrificing at least 365,000 of their own people to end slavery in the South. Estimates of total Civil War deaths range from 625,000–850,000, in exchange for the freedom of 3 to 4 million people.

And by 1870, African Americans were given the right to vote.

Other than the printing press, what caused this radical shift in attitudes?

The other big thing going on in America at the time was Westward Expansion.

Between 1607 and 1776, Americans didn’t even settle the entirety of of the 13 Colonies:

Zone of American settlement circa 1776

The western portions of New York, Pennsylvania, Georgia, etc., were still under Indian control. But with the end of British control, settlement expanded rapidly. A mere 55 years later, the territory had more than doubled:

Zone of American settlement circa 1820

By 1822, Americans were swarming into Mexico, soon to be known as Texas.

Interestingly, here’s how the Wikipedia describes the circumstances:

“Hoping that more settlers would reduce the near-constant Comanche raids, Mexican Texas liberalized its immigration policies to permit immigrants from outside Mexico and Spain.^[74] Under the Mexican immigration system, large swathes of land were allotted to empresarios, who recruited settlers from the United States, Europe, and the Mexican interior. The first grant, to Moses Austin, was passed to his son Stephen F. Austin after his death.

“Austin’s settlers, the Old Three Hundred, made places along the Brazos River in 1822.^[75] Twenty-three other empresarios brought settlers to the state, the majority of whom were from the United States.^[75][76] The population of Texas grew rapidly. In 1825, Texas had about 3,500 people, with most of Mexican descent.^[77] By 1834, the population had grown to about 37,800 people, with only 7,800 of Mexican descent.^{[78]” (Emphasis added)}

In 1830, Mexico attempted to halt American immigration to Texas; in 1835, the Texicans revolted. California also began receiving American settlers in the 1820s, and quickly followed a similar path.

Zone of American settlement circa 1835

By 1848, Mexico had lost half its territory to the US, officially opening up almost the entire continental US to American settlement. By 1861, California Oregon, Texas, and Kansas had become official states, not just territories:

 

American states in 1861

Let’s take a closer look at this map.

Red = States that seceded before April 15, 1861

Light Red = States that seceded after April 15, 1861

Yellow = States that stayed in the Union, even though they permitted slavery

Blue = Union states where slavery was illegal.

I don’t know what’s up with Kentucky, but Missouri had significant populations of both Southerners and Northerners. Maryland and Delaware, as we’ve discussed, were already well on their way toward ending slavery when the war broke out, and were basically occupied by Union troops, anyway, due to their proximity to DC.

The difficulty of this sort of map is that it only shows the territorial borders of the states, rather than the population densities; parts of West Texas today probably have a lower population density than many parts of the non-state territories on this map. Regardless, the nation had expanded quite a bit in the <100 years since independence, and seems to have been expanding faster in the North than in the South.

At the same time as Northerners were leaving the coast in droves, more immigrants, eg Irish and Germans, were arriving from Europe. The Germans were particularly selected for liberalness, being the losers of the 1848 rebellions against the German government; Thomas Edison’s father was a refugee from a failed Canadian independence bid.

In sum, I propose that Westward Migration in the 1800s drew disproportionately from the East Coast’s more conservative folks–the guys most likely to drag an abolitionist through the streets and tar and feather him–thus leaving behind a population of more liberal folks. This caused a radical shift in the ideas being discussed in the North as there were simply fewer pro-slavery arguments to be heard, and public consensus therefore shifted suddenly leftward.

“But wait,” I hear you saying, “Didn’t the South expand Westward, too? Why didn’t that cause the South to go liberal?”

A few factors:

1. The South started out more conservative than the North, so even if it did become more liberal over time, it still would not have become as liberal as the North.
2. The South probably received fewer liberal Germans and Canadians, though don’t cite me on that because I know a lot of Germans settled in Texas.
3. The South is really inhospitable, especially to whites:

Take a good look. Houston is on the same latitude as Cairo. North Carolina is at the same latitude as Tunisia. Florida is down by Western Sahara. Even Washington, DC, is only at the latitude of Spain, southern Italy, Greece, and Turkey.

Most Southerners hail from places too far north to even show up on this map. To get to London,’s latitude, you’d have to go to the northern tip of Newfoundland, Canada. For Scotland, you’d have to go to Labrador.

Whites did not thrive in the South. It was really hot, swampy, and full of diseases they had no immunity to, like Malaria and Yellow Fever, which arrived with the African slaves and quickly spread. The population was suffering widespread malnutrition due to inadequate, improperly prepared food and parasites like Necator Americanus, “American Killer”, aka hookworms, which also came over with the slaves. When people finally figured out what was causing all the anemia and began eradicating hookworms, they discovered that about 40% of Southern children were infected.

Since these diseases were endemic to Africa, their effect on the black population was less devastating; it’s no wonder that the Scottish and Scotch-Irish settlers in the South migrated up into the cooler regions of the Appalachians and stayed there, leaving the low-lying areas open for black settlement.

As a result, the Southern economy and population grew very slowly, especially compared to the North. It has only been since the invention of air conditioning that much of the South has become remotely inhabitable by whites; Houston, Texas, would be nothing but a speck of dust on the map if it weren’t for AC.

The North, by contrast, had an abundance of land at its disposal that wasn’t riddled with malaria-infested swamps, and so could expand quickly.

So not only was the South not expanding as quickly as the North, Southern whites really did see themselves as at a biological disadvantage to blacks, who did not suffer as much from the Southern diseases and heat.

4. As a result, obviously, the Southern economy was actually more tied up in slavery than the Northern economy, where it had never been as big a factor and the long winters gave the environmental upper hand more to whites, and it is obviously going to take longer for attitudes to shift in a place where eliminating slavery going to be a big deal than in a place were there weren’t a whole lot of slaves to start with.

So environmental factors basically colluded to dampen an effects of Western migration in the South while the North expanded freely, leading to an acceleration in political changes in the Northern cities, resulting in a sudden willingness to go to war over the issue.

Tesla, Edison, Genius, and Loneliness (part 2/2)

Part 1 is here.

“If I am walking with two other men, each of them will serve as my teacher. I will pick out the good points of the one and imitate them, and the bad points of the other and correct them in myself.” — Confucius

This quote is one of my personal mottoes, but I have added a corollary: “If I am walking with only one man, I still have two teachers, for I may learn to achieve goodness from a man’s good side, and to avoid evil from a man’s bad side.”

At any rate, Edison is a man whose goodness instructs us on how to take brilliant ideas and build the structures necessary for them to benefit humanity. Edison is a man who literally built civilization and deserves credit for both seeing how the structures needed to fit together to work, and for having the skills necessary to actually bring people together and build those structures.

Tesla is a lesson on how society should not manage its creative geniuses, (and I don’t mean the dumb pay dispute with Edison.)

Tesla is an interesting character. He appears to have been one of the world’s exceedingly rare true short sleepers, which appears to be a genetic condition:

“Ying-Hui Fu … studies the genetics and other characteristics of short sleepers at her neurogenetics lab.

“Currently, Fu knows of three types of genetic mutations that are related to the ability to function well on minimal amounts of sleep, which often runs in the family. In a 2009 paper published in the journal Science, she described a mother and a daughter who shared the same genetic mutation of the gene DEC2 that allowed them to thrive on six hours of sleep per night. So far Fu has identified about 50 families of short sleepers.

“This group of short sleepers is unique,” Fu said, describing them as optimistic and energetic, often holding more than one job. …

“Interestingly, these high energy levels typical of short sleepers can sometimes reach behavioral extremes. For instance, a 2001 study published in the Journal of Sleep Research that examined the sleep patterns and personality of 12 short sleepers, researchers found some evidence of subclinical hypomania — a milder form of manic behavior, characterized by euphoria, disinhibition and, in fact, a decreased need for sleep.”

Please note that drinking 10 5-hour-energy drinks in a row is not the same as having a genetic mutation that lets you get by on less sleep. Chances are extremely likely that you, my friend, are already not getting as much sleep as you need for optimum health. Also, since very few short sleepers have actually been studied, what we think we know about them may not be entirely accurate; they may suffer long-term consequences that have not yet been documented, for example. I do wonder if chronic lack of sleep eventually got to Tesla, reducing him to a state of waking-dreaming toward the end of his life, when he began going obviously loopy.

 

Tesla’s rigidity of personality, behavior, and dress are reminiscent of the compulsive, repetitive, and restrictive behaviors associated with autism/Asperger’s Syndrome (now just another part of “autism” in the DSM,) eg,

“People with Asperger syndrome display behavior, interests, and activities that are restricted and repetitive and are sometimes abnormally intense or focused. They may stick to inflexible routines, move in stereotyped and repetitive ways, or preoccupy themselves with parts of objects.

“Pursuit of specific and narrow areas of interest is one of the most striking features of AS.^[1] Individuals with AS may collect volumes of detailed information on a relatively narrow topic such as weather data or star names, without necessarily having a genuine understanding of the broader topic.” (Wikipedia.)

I’ve long thought it a problem that these definitions/descriptions make no effort to distinguish between “Aspies” and genuinely intelligent people, who simply have more ability to memorize facts of any sort and will learn about any subject in more depth than someone of ordinary intelligence. If we want to define high IQ as a mental disorder, then, well, I guess we can, but it seems like a bad idea to me.

Autistic children apparently also have difficulty sleeping, which is why many of them are being prescribed melatonin as a sleep aid (as I discussed back in Melanin, Sexuality, and Aggression.) However, these autistic kids appear to actually need more sleep than they’re getting; they just seem to have trouble turning off their brains and keeping them off long enough for a proper sleep.

Anyway, to get extremely speculative: Much like Fu’s short sleepers, the autistic people I have worked with personally (N=small) seemed like they had brains on overdrive. Imagine that a normal brain is an Amish buggy, going along at a nice, reasonable clip, and their brains are Formula One race cars. Brain speed in this case may have nothing to do with IQ, per say, or may in fact be detrimental to it–autistics are far more likely than the general population to test as mentally retarded–but I favor a theory that having a small quantity of autistic-like traits may be useful for people in fields or occupations that require high IQ, but large quantities of autistic-like traits cause too many negative side effects, resulting in full-blown autism. In Tesla’s case, he got the benefits of the massively high-powered, sped-up brain, with a side effect that he couldn’t turn it off long enough to get more than a few hours of sleep and lacked the normal social instincts that lead people to marry, have children, and generally form stable relationships with other people.

There’s a certain irony to Tesla advocating for sterilization of the unfit and hanging out with Nazi propagandist George Sylvester Viereck at the same time as the Nazis were ignoring Hans Asperger’s plea that his subjects be employed as codebreakers and executing them as mental defectives instead. But then, the Nazis are kind of a great big case of how not to treat your smart people.

To be fair, this is not evidence that Tesla actually supported the Nazis or their policies.

Back in Is Genius Fragile?, I discussed a recent paper in Molecular Psychology that claimed to have studied 1,400 students with IQs of 170 or above, and found no rare genetic alleles that were more common in them than people of normal or low IQ, but did find rare, deleterious alleles in regular/dumb people.

Edit: I just realized that for scheduling reasons, “Is Genius Fragile” actually got moved to mid-November. The Molecular Psychology paper is here.

But are such alleles actually deleterious? Tesla never married and had no children; neither did Isaac Newton. Einstein had three children, but one of them seems to have died in infancy and one was institutionalized for schizophrenia.

In other words, perhaps some of these alleles they’ve noticed aren’t deleterious, but actually helpful in some way. Perhaps, for example, there is an allele that codes for processes that help you turn off your brain at night and transition to certain sleep states. Without that allele, your brain is more “on” all the time, you feel more alert and can think more clearly than others without getting tired, but ultimately there are some bad side effects to not sleeping. Or perhaps the brain’s ability to see patterns is normally regulated by another mechanism that helps you distinguish between real patterns and false matches, which might malfunction in people like John Nash, resulting both in increased pattern-matching ability and in schizophrenia. By the way, I am totally speculating and might be completely wrong.

Please note that from the evolutionary POV, traits–like IQ–are not inherently valuable. A trait is adaptive if it leads to the continuation of your DNA into future generations, and is deleterious or maladaptive if it hinders the continuation of your DNA. If high IQ people do not have children, the high IQ is maladaptive and being selected out of the population. (Please note, also, that different environments, both physical and cultural, select for different traits. Had Tesla remained near his family back in Croatia, they might have helped arrange a marriage for him, leading eventually to children and romantic entanglements with someone who wasn’t a pigeon.)

However, even if high-IQ people never reproduced under any circumstances, their existence in a population might still be advantageous to the population as a whole–you probably enjoy having lightbulbs, electricity, cell phones, and other such things, for example. The development of vaccines, industrial agriculture, and modern theories about nutrition and hygiene have vastly expanded the Earth’s human population over the past hundred years, and would have done so even if the people involved had not had any children at all.

This is a somewhat complicated issue that depends on the interaction of a lot of variables, like whether society can consistently produce high-IQ people even if the high-IQ people themselves do not have many children, and whether the innovations of modernity will actually help us survive (the Amish, after all, have more children than your average person with a cell phone.) See: “How–and why–genius is group selected–massive cultural amplification” for some more discussion on the subject.

Regardless, I am operating under the assumption that society benefits from the existence of people like Tesla (and, of course, Edison.)

Anyway, back to Tesla and his job difficulties.

In “The Improperly Excluded,” Micheal Ferguson theorizes that there exists a maximum IQ difference between two people beyond which they cannot effectively communicate, which he places around 20 IQ points. (I think I discussed it here and here.) So a person with an average IQ of 100 can understand and communicate with someone with a 120 IQ, and someone with a 120 can understand a 140, but the 100 and 140 are essentially speaking Greek to each other; the 100 IQ person cannot make heads or tails of the 140’s thoughts, nor distinguish their claims from those of a crazy person or charlatan. If the 100 trusts the 120, the 120 can take advice from the 140 and recommend it to the 100, but beyond that, people of, say, 160 IQ are just too far removed from the average population to even get their ideas effectively communicated. Extremely high IQ people, therefore, may be improperly excluded from positions where they could actually do important work just because average people have no way to understand what they’re saying. Additionally, since extremely high IQ people are very rare, they may have to cope with a world in which almost no one they meet is within their comfortable conversation zone.

Note: see Hollingworth Fan’s comment below for some very interesting quotes on this subject.

Tesla, a guy who could do integer calculus in his head, was undoubtedly brilliant far beyond the common walks of man, and so seems to have faced the constant frustration of being surrounded by idiots like Edison. Upon Edison’s death, Tesla opined in the NY Times about his former boss:

“He had no hobby, cared for no sort of amusement of any kind and lived in utter disregard of the most elementary rules of hygiene … His method was inefficient in the extreme, for an immense ground had to be covered to get anything at all unless blind chance intervened and, at first, I was almost a sorry witness of his doings, knowing that just a little theory and calculation would have saved him 90 percent of the labor. But he had a veritable contempt for book learning and mathematical knowledge, trusting himself entirely to his inventor’s instinct and practical American sense.”

That idiot Edison, by the way, had six children, none of whom seem to have died in infancy or gone crazy. Three went into science/inventing, two were women, and I don’t know what happened to the fourth boy. Edison was undoubtedly helped in life by living in the same country as his family, but he also seems to have just been a more stable person who successfully managed to balance his work and social life. Edison: better adapted to his environment than Tesla.

Tesla’s genius was undoubtedly under-utilized. Tesla could not manage his own affairs, and so needed, at the very least, the strong structural support of a family that would prevent him from doing stupid things like gambling away his tuition money and dropping out of college, as well as a sound employer or university that would manage the business end of Tesla’s laboratory expenses and design implementation. Immigration to the US left Tesla without the support of his family, and his own stubbornness lead him to quit what would otherwise have been a productive career.

Additionally, Tesla’s ideas may truly have been too far ahead of their time for even other smart people to appreciate and understand. There were few people in the world at his level, and he must have spent much of his life completely isolated from anyone who could understand him. Even an employer willing to finance his schemes might not have been able to understand (and thus implement) some of them.

Isolation, I suspect, leads eventually to madness. Not because (or just because) isolation makes people lonely, which makes them depressed. But because the human animal is not designed to work in isolation.

In the extreme example, we know from observing people in solitary confinement that it breaks their brains and drives them insane.

In everyday life, our brains require regular feedback from others to make sure our ideas and impulses are correct. To give a trivial example, suppose I mention to my husband that a friend of mine did something today that really annoyed me, and he responds that I am misinterpreting things, that he heard from my friend’s husband that morning about some extenuating circumstances that explain her behavior and that I should not be annoyed with her. Likewise, he might come to me with a story about a co-worker who seems to be stealing his ideas, and I could help figure out if the guy really is.

Isolation removes this feedback, leading to more and more incorrect ideas.

In his recent post, “Mysticism and Pattern-Matching,” Scott Alexander writes:

“Think of top-down processing as taking noise and organizing it to fit a pattern. Normally, you’ll only fit it to the patterns that are actually there. But if your pattern-matching system is broken, you’ll fit it to patterns that aren’t in the data at all. …

“So hallucinations are when your top-down processing/pattern-matching ability becomes so dysfunctional that it can generate people and objects out of random visual noise. Why it chooses some people and objects over others I don’t know, but it’s hardly surprising – it does the same thing every night in your dreams.

“Many of the same people who have hallucinations also have paranoia. Paranoia seems to me to be overfunctioning of social pattern-matching. … When a paranoiac hears a stray word here, or sees a sideways glance there, they turn it into this vast social edifice of connected plots.”

Tesla’s claims to have been working on a “Death Ray” that turned out to be an old battery, his romantic entanglement with a pigeon, claims that “thieves” had broken into his hotel room in search of his “Death Ray” but not been able to find, and the Mythbusters’ thorough busting of his claims to have built an oscillator that nearly brought down the building and had to be destroyed with a sledgehammer all sound a lot like what Scott’s describing. As a guy who could do calculus in his head, Tesla had an extreme talent for pattern matching–perhaps too extreme. Scott continues:

“So to skip to the point: I think all of this is about strengthening the pattern-matching faculty. You’re exercising it uselessly but impressively, the same way as the body-builder who lifts the same weight a thousand times until their arms are the size of tree trunks. Once the pattern-matching faculty is way way way overactive, it (spuriously) hallucinates a top-down abstract pattern in the whole universe. This is the experience that mystics describe as “everything is connected” or “all is one”, or “everything makes sense” or “everything in the universe is good and there for a purpose”. The discovery of a beautiful all-encompassing pattern in the universe is understandably associated with “seeing God”.”

Recovered schizophrenics I’ve talked to report the exact same thing: both a mystical sense of the union of all things, and joy at the experience (though they also report that schizophrenia can be absolutely terrifying, because sometimes the voices are evil.)

And finally (at least for the quoting):

“I think other methods of inducing weird states of consciousness, like drugs and meditation, probably do the same thing by some roundabout route. Meditation seems like reducing stimuli, which is known to lead to hallucinations in eg sensory deprivation tanks or solitary confinement cells in jail. I think the general principle is that a low level of external stimuli makes your brain adjust its threshold for stimulus detection up until anything including random noise satisfies the threshold.”

Isolation/ lack of stimulus has a direct effect of lowering the brain’s threshold for identifying patterns until random background noise gets interpreted as conversation. (The general correlation between schizophrenia and low IQ could be partially an effect of smarter people being better at avoiding severe isolation, and dumber people being more likely to end up in situations where literally no one has a real conversation with them for years at a time.

Tesla seems to have been isolated in his own way, both by being far more intelligent than the vast majority of people, and so unable to converse properly with them, and also by having none of his family, kin, or fellow countrymen around. He even had to communicate primarily in a language that was hardly his first.

Long term, I suspect such isolation had a negative effect on Tesla’s sanity and ability to wisely conduct his own affairs.

 

Tesla is a difficult case, because he willingly walked away from what were probably excellent career opportunities, and there’s hardly anything anyone could do about his family being back in Croatia. However, since most people do live in the same country as their families, we can still draw some general conclusions:

Some really smart people may require significant support from society and/or their families/employers in order to properly function and fully realize their potential. Their families should probably step in and help them get married if they can’t do it themselves, at the very least to help keep them happy and stable.

The Wikipedia quotes physicist Y. S. Kim on the subject of P. A. M. Dirac (one of my favorite scientists)’s marriage to Margit Wigner, sister of Nobel Prize winning theoretical physicist Eugene Wigner:

“It is quite fortunate for the physics community that Manci took good care of our respected Paul A. M. Dirac. Dirac published eleven papers during the period 1939–46…. Dirac was able to maintain his normal research productivity only because Manci was in charge of everything else.”

Dirac and Manci in Kopenhagen

Alas, the Wikipedia does not give the details of how an autist like Dirac managed to marry Manci.

Really smart people may have some ideas that are astounding brilliant, and also have a lot of ideas that don’t work at all, because that is just the nature of creativity, but the average person probably can’t tell the difference. They need other people like themselves to bounce ideas off of and generally converse with. Their eccentricities are generally harmless, and the community is better off tolerating them.

Above all, try not to abandon them. Humans are not built to be alone.

Theory: the inverse relationship between warfare and homicide

That whole myth about hunter-gatherers being peaceful and non-violent probably got its start because hunter-gatherers tend not to be as good at organized warfare as the Germans.

Homicide is an act of disorganized impulsive passion; warfare is an act of organized dispassion; the two are inverse of each other. Thus we see the highest homicide rates in the world’s least developed countries, and the lowest rates in its most developed countries.

 

Note that it is not an absolutely perfect correlation; many Latin American or Caribbean countries have higher homicide rates than even less-developed countries in Africa, but broadly speaking, the pinks and reds are poorer than the blues. (Russia excepted, ‘cuz Russia.)

Also, as you may recall:

Test launch of India’s GSLV Mk III

But have you heard of the Congolese space program?

To be fair, it’s more “One guy with a rocket-building hobby” than a real space program, but I understand where he’s coming from. Rockets are cool.

The point of all of these maps and graphs is that homicide rates tend to be highest, both today and throughout history, in the places with the lowest levels of social organization/complexity.

Even in our own society, convicted criminals are overwhelmingly lacking in the ability to handle complexity. It looks like they aren’t really all that much more retarded (note: PDF) than the general population (the truly intellectually impaired are often pretty highly supervised and lack the ability to execute many crimes, but are often victims of violence,) but they are drawn disproportionately from the dumber half.

According to respondents in the AR15.com forum thread “Cops and Lawyers – What percent of criminals/clients are retarded?” (Note: I know nothing about this forum or its reliability)

“Not retarded per se. My personal experience is most criminals stopped developing emotionally at about 3 or 4. They live life for the moment, think only of themselves, have no impulse control, can’t control their emotions, throw temper tantrums when they don’t get their way, can’t think past the next 10 minutes, don’t understand consequence, etc……. They are basically little children in adult bodies. Of course, most 3 or 4 year olds are better behaved than the average criminal, but you get the point.”

“I found that better than 90% of them were functionally illiterate, so when they say reading is fundamental, they aren’t kidding!”

“With the advent of welfare, it became profitable to squirt out children.It relegated men to the status of semen injectors. No men, no fathering. down the spiral 40 odd years and we’ve got multiple generations of female children “raising” children.
The results aren’t retarded, they are more like Comanches or Lakota, they have regressed several thousand years.
It is painful to watch good officers try to “reach” these kids. Watching with an unsympathetic eye, it is plain that most of these kids don’t even understand what the officers are talking about.
That’s the brutal truth that no one wants to face. These kids aren’t just lost-they are damned in our society.”

Recall our discussion back in Two Kinds of Dumb–just because someone has a low IQ, doesn’t mean they are retarded. But anyone who is illiterate (in our society) with the emotional maturity of a 3 or 4 your old is not very bright or capable of thinking through the results of their own actions.

The art of killing large numbers of people, by contrast, requires organization. One guy with a pointy stick might kill a few dozen guys who don’t have pointy sticks, but one guy who convince a thousand other guys to stand next to you with their pointy sticks, and you get this:

Source: Chapleton

The Romans didn’t conquer an empire by poking barbarians with pointy sticks; they did it by organizing themselves into an unstoppable war machine.

Armies do not generally fund themselves; they depend upon a vast support structure producing weapons, food, transportation, shelter, technology, etc. The bigger the army and more advanced the weaponry, the bigger the support structure has to be. Nukes take far more people to produce than pointy sticks, from the farmers making the food to feed the scientists working out the details to the structural engineers building the research labs to the guys building the rockets or planes to drop the bombs.

Complex organization requires large numbers of people working in close proximity without punching each other; it requires that people be able to suppress their own personal desires in pursuit of the group goal. All of this requires being less violent, less impulsive, and less inclined toward murdering each other.

Judeo Ethnogenesis

Disclaimer: I had 3 hours of sleep last night. Weigh that carefully before testing my patience.

Ethnogenesis, as the name implies, is the process whereby a new ethnic group is created. An ethnicity is more or less a group with a shared culture, belief in common ancestry, and that preferentially marries within itself rather than outside of itself. Over time, this creates a group that is ethnically distinct from its neighbors, even under conditions of close proximity.

The Amish, for example, after splitting off from the Swiss in the 1600s over religious differences (remember, religion is ethnicity,) arrived in Pennsylvania in the early 1700s, so we may mark Amish ethnogenesis around the mid 1600s or early 1700s People today make fun of Ben Franklin for complaining that the German-speaking immigrants to Pennsylvania were problematic and not integrating with the rest of the population, but you know, the Amish still haven’t integrated. They still speak German, follow their own religion and traditions, and don’t inter-marry with the rest of the Pennsylvania population, such that they are quite ethnically distinct, at least on a genetic level.

The Hui of China are another example; they were not really considered an ethnic group before the establishment of the People’s Republic of China circa 1949. The Chinese decided to just lump all of their Muslim minorities–some of them quite distinct–under one term. (Historically, the term “Hui” also referred to Christians and Jews and was just a general catch-all.) Hui now marry other Hui preferentially enough that the Wikipedia page goes into detail on known cases of inter-marriage with the Han, but a fellow Hui from across the country may be regarded as just another Hui, and so a preferred partner.

Anyway, so that got me thinking about the establishment of Israel. Normally when I think of Jews, I am actually thinking of Askenzim, and you probably are, too. But Israel is actually 61% Mizrahi Jews–Jews from predominantly Muslim countries.

You know the general story: Once upon a time, all of the Jews lived in Israel. These people were probably pretty similar, ethnically, to the Palestinians, assuming the Palestinians are anything like the region’s residents 2000 years ago, and don’t have a massive influx of Turkish DNA or something like that.

Then the Jews got conquered and scattered to the winds. Most famously after the destruction of the Second Temple by the Romans, but also during the Babylonian  and Assyrian eras, etc. Anyway, for the past 2000+ years or so, there have been significant Jewish communities in a lot of places that aren’t Israel, eg:

Uzbeki Jews

Chinese Jews

Ethiopian Jews

Cochin Jews

Lemba Jews?

Then in the late 1800s, the Jews–mostly Ashkenazim, I think–got sick of this state of affairs and decided to exit Europe and go back to Israel. Unfortunately, they didn’t really succeed until 1948, at which point Jews from all over the world started pouring in.

Since most people are genetically similar to their neighbors, eg the Palestinians and Syrians, or Han and She, I began wondering how similar Jews were to their neighbors of millenia verses their similarity to each other.

Here’s a graph showing major genetic lineages of a bunch of different ethnic groups, including several Jewish ones:

Broad cultural zones are easily distinguished, like East Asians in yellow, South Asia in greens, Europeans with their large dark blue chunk, Middle Easterners with their big patches of light green and light blue, and the rust-tones in sub-Saharan Africa. This data set is great, because it lets us compare various Jewish groups to their immediate neighbors, eg:

I made a condensed version of the graph that highlights the measured Jewish groups and their neighbors, (sadly, some of the samples are pretty small, making them hard to read):

And an even more condensed version that just compares the Jews to each other:

(Note that the pure green section on the right-hand side is not a Jewish group, but just a chunk of the graph that happened to overlap the text due to the Cochin Jewish section being so small.)

Observations: Most Jewish groups are significantly more similar to their immediate neighbors than they are to other Jewish groups, especially when we look at the furthest-flung folks. Cochin Jews and Ethiopian Jews, for example, show almost no DNA in common (in this graph.)

Given what all Middle Eastern groups look like in the sample, we may speculate that the original Jewish group primarily had a large section of light blue and a slightly smaller section of light green, with probably a smidge of sub-Saharan. Several of the Middle Eastern Jewish groups still have this genetic makeup.

Three Jewish groups show a more European makeup, with a large dark blue chunk characteristic of Europeans and North Africans: the Ashkenazim, Sephardim, and Moroccan Jews. They look closest to Cypriots, though I compared them to Spaniards and Tuscans as their nearest neighbors in the graph.

Since the Ashkenazim are estimated to be about half Italian, it’s not surprising that they have about half as much dark blue as the Italians. Even within European groups, while they look fairly similar at this level of resolution, some groups are quite distinct from each other–Italians and Germans, for example, or Brits and Greeks. Geneticists can determine whether your ancestors were Italians or Germans or Greeks just by looking at your DNA, but those kinds of small details don’t really show up all that well on a graph that is trying to show the differences between Sub-Saharan Africanss and Asians. So while Moroccans, Sephardim, and Ashkenazim all look rather similar here, there may be finer grained differences that just don’t show up at this scale.

What’s up with the Moroccan Jews? They do not look like Moroccans; I therefore speculate a more recent migration of Moroccan Jews from somewhere else that’s not Morocco, like Spain.

The Jews who migrated to the East, however, lost a significant portion–almost all–of their light blue component, replacing it with dark green more typical of Indians and other SE Asian populations.

I don’t think this dataset contains Uzbeki Jews (or the Lemba, who are not Jewish enough to be considered Jewish, but still have a few Jewish traditions and folktales and a bit of Jewish ancestry,) which is sad, but I’d wager the Uzbeki Jews look a lot like other Uzbeks.

One of the things I’ve heard often from Jews is that all Jews are Jews, part of one great big Jewish family descended from Abraham (even the atheist ones!) and thus Jews should always try to be kind to each other, all Jews are welcome in Israel, etc. This is a perfectly sensible philosophy when you’re a peasant in Poland and the only foreign Jews you’ve ever met were from Lithuania. But 2000+ years of diaspora have resulted in far flung groups becoming quite ethnically distinct from each other. Like the Amish, isolated groups in Cochin or Ethiopia have become their own ethnies distinct from their ancestors, but unlike the Amish, they have inter-married significantly with the locals. (The Amish do not marry non-Amish.)

The Roman Exile, therefore, should be regarded as a major ethnogenesis event–the beginning of the creation of most current Jewish ethnic groups.

The creation of the state of Israel constitutes a second major ethnogenesis event, a bringing together of these multiple ethnic groups into one population that views itself as one population. I expect a great deal of mixing between these historically distinct groups into a more homogenous whole, (though some groups don’t mix terribly well, like certain Ultra Orthodox communities that haven’t been accepting of Ethiopian Jews.)

Species of Exit: The Sentinelese, the world’s most isolated people

North Sentinel Island

Map showing location of North Sentinel Island (red) relative to the rest of the Andaman Islands

Map showing the distance between the Andaman Islands (small islands south of Myanmar) and land.

The Sentinelese appear to have split off from the rest of humanity approximately 48,500 years ago, and aside from occasional contact with other members of the Andaman islands, have remained isolated ever since.

People have occasionally landed on or near Sentinel island, but the islanders have all resisted contact, generally by shooting arrows at anyone who gets too close. Even National Geographic hasn’t got any pictures of them–when they tried to make a documentary on the island, armed with gifts, they had to retreat after the director took an arrow in the thigh. The last guys whose boat accidentally drifted onto their beach got killed and buried in shallow graves on the beach.

North Sentinel Island is technically owned by India, but India has given up trying to make peaceful contact, and it would probably look bad to just bomb the place.

So what do we know about the Sentinelese?

Obviously not a whole lot, since most of what we know of them has been observed from a distance.

The whole island is about the size of Manhattan, and probably inhabited by 40-500 people. They’re generally characterized as Negritos, a term used for the shorter than average but taller than Pygmies, dark-skinned people of the Andaman Islands and certain groups in the Philippines, Thailand, and Malaysia. The term is only descriptive; different Negrito tribes may not be related to each other at all. (I promised I’d get around to the Negritos eventually.)

Aside from stuff that has randomly washed up on their island or was given to them by folks trying to make contact, they have only stone tools and, according to the Wikipedia, appear not to have fire.

But a little more research suggests that Wikipedia may just be wrong on this point; during the search for the lost Malaysian jetliner, smoke was observed rising from North Sentinele, which implies that the people there probably do have fire.

At any rate, we do know that they have bows and arrows, boats, and spears.

When National Geographic tried to make contact, they left a plastic toy car, coconuts, a live pig, a doll, and aluminum cookware on the beach before getting shot at. After they retreated, they observed the Sentinelese shoot and bury the pig (not eat it?) and, if the Wikipedia is accurate, shoot and bury the doll. They took the coconuts and pans; no word of the car’s fate.

In 1970, a group of Indian anthropologists that came near the island had a decidedly strange incident:

Quite a few discarded their weapons and gestured to us to throw the fish. The women came out of the shade to watch our antics… A few men came and picked up the fish. They appeared to be gratified, but there did not seem to be much softening to their hostile attitude… They all began shouting some incomprehensible words. We shouted back and gestured to indicate that we wanted to be friends. The tension did not ease. At this moment, a strange thing happened — a woman paired off with a warrior and sat on the sand in a passionate embrace. This act was being repeated by other women, each claiming a warrior for herself, a sort of community mating, as it were. Thus did the militant group diminish. This continued for quite some time and when the tempo of this frenzied dance of desire abated, the couples retired into the shade of the jungle. However, some warriors were still on guard. We got close to the shore and threw some more fish which were immediately retrieved by a few youngsters. It was well past noon and we headed back to the ship…

Virtually nothing is known about the Sentinelese language, though it is speculated that it is related to the Onge language of the Andaman islands. However, attempts at using the Onge as translators have failed, as the Onge themselves cannot understand a word of Sentinelese.

A British expedition in the 1880s that got a decent look at the island claimed that, of all the nearby groups, Sentinelese culture most closely resembled Onge culture, so it is still possible that the languages are related, albeit distantly.

Since much more is known about the Onge, I’m going to speak briefly about them:

Onge man collecting honey, Andaman Islands

The Onge are marked in blue on the map above; today they live chiefly on Little Andaman Island in the south, but in the past they ranged further north, closer to to the Sentinelese. Contact with the outside world has reduced their population from almost 700 people (1900) to about 100. (There may well have been >700 people before 1900, that’s just the first date I have numbers for.) Strangely, the Onge appear to be the world’s least fertile people, with 40% of couples suffering infertility. Wikipedia estimates their Net Reproductive Rate (similar to TFR, but only looks at daughters) at 0.91, which is below replacement, however, their population appears to have held steady for the past 30 years, so perhaps the problem is working itself out.

Why such infertility? The most obvious guesses (IMO) are some sort of environmental poison/effect; some sort of diseased-induced infertility, like gonorrheal scaring (please note that I have no idea if any of the Onge have ever had gonorrhea, but it is a common cause of infertility;) or a side effect of inbreeding/lack of genetic diversity following their extreme population collapse.

The article Malnutrition and high childhood mortality among the Onge tribe of the Andaman and Nicobar Islands suggests that the real cause of the low NRR is high childhood mortality due to malnutrition/insufficient food, probably due to loss of their traditional hunting/gathering grounds.

Genetically, the Onge appear to have been isolated for an extremely long time. They all share the same mitochondrial DNA, haplotype M32, which is not found anywhere outside of the Andaman Islands. (The larger umbrella-group M, to which all M-varieties belong, is one of the world’s most wide-spread lineages, emerging either shortly before the Out of Africa event, or shortly after it, but is most reliably concentrated in Asia, with several ancient lineages in India.)

The Onge language is related to the languages of some of the other tribes in the Andaman Islands, and speculated to be part of the greater Austronesian language family. (Considering that the whole Indo-European language family is about, what, 4-6,000 years old, I am a little skeptical of our ability to reconstruct too much about a language that may have diverged 40,000+ years ago.)

Onge Y-DNA belongs to Haplogroup D-M174, which emerged in Asia about 60,000 years ago and isn’t found outside of Asia. It is found today among Tibetans, the Ainu, and the Andaman Islanders, suggesting that these people are all (at least partially) descended from a common source that split off from other humans around 60,000 years ago, or just after the OoA (relatively speaking.) D-M174 is also found in small amounts in China and central/east Asia.

The Ainu, IIRC, also have a particular tooth shape that is commonly found in Melanesia, but not outside of it, and a small amount (about 15%, I think,) of Siberian DNA. And, of course, we now have evidence of Melanesian DNA showing up in the Amazon rainforest, not to mention the curious concentration of archaic Denisovan admixture in Melanesians, despite the only Denisovan remains we’ve found so far coming from Russia. However, it appears that there is no Denisovan DNA in the Andaman Islanders, so maybe they split off before the Denisovan admixture advent.

The sum of the evidence suggests a single band of people, perhaps most closely resembling the Negritos, spread 60,000 years ago along the coast of southern Asia and spread far into the interior, reaching at least as far as Tibet, the Andaman Islands, and northern Japan, and possibly even crossing the Bering Strait and down to the tip of South America. (Since Melanesians do not appear to have ever spread to Polynesia, I suspect they did not boat straight across the Pacific, but maybe we just haven’t yet found Melanesian remains in Polynesia.)

Over the ensuing millenia, later population waves, like the Polynesians and the common ancestors of east Asians like the Han and the Japanese, migrated into the area, leaving only a few isolated remnants of Haplogroup D-M174 in far-flung, difficult to reach places like the Andaman islands, the Himalayan Plateau, and the coldest parts of Japan. Likewise, Melanesian DNA in the New World seems to have best survived in one of its harshest, most difficult to penetrate habitats: the rain forest.

This all gets back to my theory of genetic survival at the fringes, (discussed here,) which I hope to devote a full post to soon. The history of the world is the group with better tech conquering the group with worse tech, and then getting conquered in turn by a group with even better tech.

The island of Taiwan illustrates this well; the most recent immigration wave happened in 1949, when the ROC lost their war with the PRC and evacuated 2 million of their people to Taiwan, a nation of 6 million at the time. Taiwan had previously (temporarily) been conquered by the Japanese, and before that, by other Chinese people, who began arriving around 1300. They’ve been gradually defeating/replacing the aboriginal Taiwanese, who are now a very small population, and the aboriginal Taiwanese themselves have legends about having wiped out a negrito-like people who predated their arrival, but I consider such legends only potentially true. Each group got conquered by the next group with better tech.

A couple more pictures of Andaman Islanders:

Andamanese Couple, Wikipedia

Anyway, back to the Sentinelese.

The available evidence suggests that they split off from the rest of the human population ages upon ages ago, and have been effectively isolated from everyone but their immediate neighbors ever since. Though technically their island is considered part of India, as a practical matter, they govern themselves. They have managed to retain their independent status for so long by living on a tiny, hard-to-reach island and enforcing a strict immigration policy of killing anyone who shows up on their beach.

Given that the Sentinelese would probably all die of the common cold if they ever did let foreigners onto their island, their policy is not unreasonable. You wouldn’t want to let some plague-bearing foreigner kill you with their germs, either. Unfortunately, the disease situation is unlikely to reverse itself; their population is just too small to withstand contact with the outside world. Too-long isolation in such a tiny place has cut them off from all the technological progress of the past 40,000 to 60,000 years, and their population is too small to develop much tech internally. To be fair, their strategy has worked so far. But now they’re stuck, maintaining their tiny island against the odds until someone decides to show up with guns and do some logging, fishing, or whatever they feel like, at which point there’s a good chance they’ll be wiped out.

Long term, total isolation is a policy with very low survival odds.

After some thought, the best option I can think of for the Sentinelese, other than continuing as they are and hoping for the best (after all, the rest of the world could destroy itself in a nuclear holocaust and leave them behind to continue doing their thing for the next 40,000 years,) is to expand their numbers and send excess people to the other Andaman Islands. Sure, most of those people would probably get colds and die, and if not the colds, alcohol’s a likely culprit, but as long as they keep exporting people, eventually some of them will survive, and create a breeding population/intermix with the other Andamanese until they have the numbers/immunity to interact with the outside world.

Further implications of hippocampal theory

So while on my walk today, I got to thinking about various potential implications of the hippocampal theory of time preference.

The short version if you don’t want to read yesterday’s post is that one’s degree of impulsivity/ability to plan / high or low time preference seems to be mediated by an interaction between the nucleus accumbens, which seems to a desire center, and the hippocampus, which does a lot of IQ-related tasks like learn new things and track objects through space. Humans with hippocampal damage become amnesiacs; rats with the connection between their nucleus accumbens and hipocampus severed lose their ability to delay gratification even for superior rewards, becoming slaves to instant gratification.

So, my suspicion:

Relatively strong hippocampus => inhibition of the nucleus accumbens => low time preference.

Relatively weak hippocamus => uninhibited nucleus accumbens => high time preference (aka impulsivity.)

Also, Strong hippocampus = skill at high IQ tasks.

Incentivise traits accordingly.

Anyway, so I was thinking about this, and it occurred to me that it could explain a number of phenomena, like the negative correlation between weight and IQ, eg:

Shamelessly stolen from Jayman’s post. As usual, I recommend it.

(Other theories on the subject: Intelligent people make lots of money and so marry attractive people, resulting in a general correlation between IQ and attractiveness; there is something about eating too much or the particular foods being eaten that causes brain degeneration.)

People generally claim that overweight people lack “willpower.” Note that I am not arguing about willpower; willpower is only a tiny part of the equation.

The skinny people I know do not have willpower. They just do not have big appetites. They are not sitting there saying, “OMG, I am so hungry, but I am going to force myself not to eat right now;” they just don’t actually feel that much hunger.

The fat people I know have big appetites. They’ve always had big appetites. Some of them have documented large appetites going back to infancy. Sure, their ability to stay on a diet may be directly affected by willpower, but they’re starting from a fundamentally different hunger setpoint.

So what might be going on is just a matter of whether the hippocampus or nucleus accumbens happens to be dominant. Where the NE is dominant, the person feels hunger (and all desires) quite strongly. Where the hippocampus is dominant, the person simply doesn’t feel as much hunger (or other desires.)

That a strong hippocampus also leads to high IQ may just be, essentially, a side effect of this trade-off between the two regions.

We might expect, therefore, to see higher inhibition in smart people across a range of behaviors–take socializing, sex, and drug use. *Wanders off to Google*

So, first of all, it looks like there’s a study that claims that higher IQ people do more drugs than lower IQ people. Since the study only looks at self-reported drug use, and most people lie about their illegal drug use, I consider this study probably not very useful; also, drug use is not the same as drug addiction, and there’s a big difference between trying something once and doing it compulsively.

Research Links High Sex Drive To High IQ, But Brainiacs Still Have Less Sex Than Everyone Else (Spoiler alert: research does not link high sex drive to IQ. Also, NSFW picture alert.)

I am reminded here of a story about P. A. M. Dirac, one of my favorite scientists:

“An anecdote recounted in a review of the 2009 biography tells of Werner Heisenberg and Dirac sailing on an ocean liner to a conference in Japan in August 1929. “Both still in their twenties, and unmarried, they made an odd couple. Heisenberg was a ladies’ man who constantly flirted and danced, while Dirac—’an Edwardian geek’, as biographer Graham Farmelo puts it—suffered agonies if forced into any kind of socialising or small talk. ‘Why do you dance?’ Dirac asked his companion. ‘When there are nice girls, it is a pleasure,’ Heisenberg replied. Dirac pondered this notion, then blurted out: ‘But, Heisenberg, how do you know beforehand that the girls are nice?'”^[30]” (from the Wikipedia.)

Folks speculate that Dirac was autistic; obviously folks don’t speculate such things about Heisenberg.

Autism I have previously speculated may be a side effect of the recent evolution of high math IQ, and the current theory implies a potential correlation between various ASDs and inhibition.

Looks like I’m not the first person to think of that: Atypical excitation–inhibition balance in autism captured by the gamma response to contextual modulation:

The atypical gamma response to contextual modulation that we identified can be seen as the link between the behavioral output (atypical visual perception) and the underlying brain mechanism (an imbalance in excitatory and inhibitory neuronal processing). The impaired inhibition–excitation balance is suggested to be part of the core etiological pathway of ASD (Ecker et al., 2013). Gamma oscillations emerge from interactions between neuronal excitation and inhibition (Buzsaki and Wang, 2012), are important for neuronal communication (Fries, 2009), and have been associated with e.g., perceptual grouping mechanisms (Singer, 1999).

Also, Response inhibition and serotonin in autism: a functional MRI study using acute tryptophan depletion:

“It has been suggested that the restricted, stereotyped and repetitive behaviours typically found in autism are underpinned by deficits of inhibitory control. … Following sham, adults with autism relative to controls had reduced activation in key inhibitory regions of inferior frontal cortex and thalamus, but increased activation of caudate and cerebellum. However, brain activation was modulated in opposite ways by depletion in each group. Within autistic individuals depletion upregulated fronto-thalamic activations and downregulated striato-cerebellar activations toward control sham levels, completely ‘normalizing’ the fronto-cerebellar dysfunctions. The opposite pattern occurred in controls. Moreover, the severity of autism was related to the degree of differential modulation by depletion within frontal, striatal and thalamic regions. Our findings demonstrate that individuals with autism have abnormal inhibitory networks, and that serotonin has a differential, opposite, effect on them in adults with and without autism. Together these factors may partially explain the severity of autistic behaviours and/or provide a novel (tractable) treatment target.”

This may not have anything at all to do with the hippocampus-NA system, of course.

Schizophrenic patients, on the other hand, appear to have the opposite problem: Hyper Hippocampus Fuels Schizophrenia?:

““What we found in animal models and others have found postmortem in schizophrenic patients is that the hippocampus is lacking a certain type of GABA-ergic [GABA-producing] neuron that puts the brakes on the system,” says Grace. “What we’re trying to do is fix the GABA system that’s broken and, by doing that, stabilize the system so the dopamine system responses are back to normal, so that we can actually fix what’s wrong rather than trying to patch it several steps downstream.””

Wow, I made it through two whole posts on the brain without mentioning the amygdala even once.

African Americans, Hispanics, and longevity

I’ve known for a while that women live longer than men, Hispanic Americans live longer than Euro Americans, and the oldest people in the US are disproportionately black:

At 116 years old, Susannah Mushatt Jones is not only the oldest woman in the US, but also the entire world.

One theory I considered was that higher infant mortality rates in Mexico (I don’t actually know the infant mortality rates in Mexico, this is just an idea,) results in the deaths of premature infants and others with severe health problems, whereas in the US these infants survive for several years–maybe even decades–before dying. The population of Hispanic immigrants, therefore, does not include these children–they’re already gone–but the US population does. This could result in a higher life expectancy among the immigrants than among non-immigrants.

But what about women and blacks? Their infant mortality would be included in the native rates, and even if worse medical care resulted in higher infant mortality among them, this still wouldn’t explain why so many supercentenarians are black.

While researching hippocampi yesterday, I ran across an article about hippocampal volumes in the elderly: Brain Morphology in Older African Americans, Caribbean Hispanics, and Whites From Northern Manhattan

We already know that different people age at different rates, but it appears as well that different races age at different rates, with black brains aging the slowest:

“Results of the regression analysis revealed significant effects of age, sex, vascular disease history, and race/ethnicity on relative brain volume (F_5,685 = 38.290, P < .001). For each additional year in age, there was an associated 0.3% decrease in relative brain volume (β = −0.003, t = 10.34, P < .001) (Figure 2). Relative brain volume among women was 2% larger than that among men (β = 0.02, t = 5.93, P < .001). Hispanic (β = 0.03, t = 7.20, P < .001) and African American (β = 0.02, t = 4.09, P < .001) participants had 2.8% and 1.6% larger relative brain volumes than white subjects, respectively. Finally, for each additional vascular disease, there was a 0.5% associated reduction in relative brain volume (β = −0.005, t = −2.70, P < .001). When interaction terms were entered into the model, none were significant, demonstrating that the association of vascular disease history and age with relative brain volume did not differ across race/ethnicity or sex. Analysis of variance controlling for age and vascular disease history confirmed main effects of sex (F_1,685 = 34.906, P < .001) and race/ethnicity (F_2,685 = 23.528, P < .001) but no sex × race/ethnicity interaction (F_2,685 = 0.167, P =.85) (Figure 3).“

So why are white males (at least in these samples) aging so quickly?

Time Preference: the most under-appreciated mental trait

Time Preference isn’t sexy and exciting, like anything related to, well, sex. It isn’t controversial like IQ and gender. In fact, most of the ink spilled on the subject isn’t even found in evolutionary or evolutionary psychology texts, but over in economics papers about things like interest rates that no one but economists would want to read.

So why do I think Time Preference is so important?

Because I think Low Time Preference is the true root of high intelligence.

First, what is Time Preference?

Time Preference (aka future time orientation, time discounting, delay discounting, temporal discounting,) is the degree to which you value having a particular item today versus having it tomorrow. “High time preference” means you want things right now, whereas “low time preference” means you’re willing to wait.

A relatively famous test of Time Preference is to offer a child a cookie right now, but tell them they can have two cookies if they wait 10 minutes. Some children take the cookie right now, some wait ten minutes, and some try to wait ten minutes but succumb to the cookie right now about halfway through.

Obviously, many factors can influence your Time Preference–if you haven’t eaten in several days, for example, you’ll probably not only eat the cookie right away, but also start punching me until I give you the second cookie. If you don’t like cookies, you won’t have any trouble waiting for another, but you won’t have much to do with it. Etc. But all these things held equal, your basic inclination toward high or low time preference is probably biological–and by “biological,” I mean, “mostly genetic.”

Luckily for us, scientists have actually discovered where to break your brain to destroy your Time Preference, which means we can figure out how it works.

The scientists train rats to touch pictures with their noses in return for sugar cubes. Picture A gives them one cube right away, while picture B gives them more cubes after a delay. If the delay is too long or the reward too small, the rats just take the one cube right away. But there’s a sweet spot–apparently 4 cubes after a short wait—where the rats will figure it’s worth their while to tap picture B instead of picture A.

But if you snip the connection between the rats’ hippocampi and nucleus accumbenses, suddenly they lose all ability to wait for sugar cubes and just eat their sugar cubes right now, like a pack of golden retrievers in a room full of squeaky toys. They become completely unable to wait for the better payout of four sugar cubes, no matter how much they might want to.

So we know that this connection between the hippocampus and the nucleus accumbens is vitally important to your Time Orientation, though I don’t know what other modifications, such as low hippocampal volume or low nucleus accumbens would do.

So what do the hippocampus and nucleus accumbens do?

According to the Wikipedia, the hippocampus plays an important part in inhibition, memory, and spatial orientation. People with damaged hippocampi become amnesiacs, unable to form new memories.There is a pretty direct relationship between hippocampus size and memory, as documented primarily in old people:

“There is, however, a reliable relationship between the size of the hippocampus and memory performance — meaning that not all elderly people show hippocampal shrinkage, but those who do tend to perform less well on some memory tasks.^[71] There are also reports that memory tasks tend to produce less hippocampal activation in elderly than in young subjects.^[71] Furthermore, a randomized-control study published in 2011 found that aerobic exercise could increase the size of the hippocampus in adults aged 55 to 80 and also improve spatial memory.” (wikipedia)

Amnesiacs (and Alzheimer’s patients) also get lost a lot, which seems like a perfectly natural side effect of not being able to remember where you are, except that rat experiments show something even more interesting: specific cells that light up as the rats move around, encoding data about where they are.

“Neural activity sampled from 30 to 40 randomly chosen place cells carries enough information to allow a rat’s location to be reconstructed with high confidence.” (wikipedia)

“Spatial firing patterns of 8 place cells recorded from the CA1 layer of a rat. The rat ran back and forth along an elevated track, stopping at each end to eat a small food reward. Dots indicate positions where action potentials were recorded, with color indicating which neuron emitted that action potential.” (from Wikipedia)

According to Wikipedia, the Inhibition function theory is a little older, but seems like a perfectly reasonable theory to me.

“[Inhibition function theory] derived much of its justification from two observations: first, that animals with hippocampal damage tend to be hyperactive; second, that animals with hippocampal damage often have difficulty learning to inhibit responses that they have previously been taught, especially if the response requires remaining quiet as in a passive avoidance test.”

This is, of course, exactly what the scientists found when they separated the rats’ hippocampi from their nucleus accumbenses–they lost all ability to inhibit their impulses in order to delay gratification, even for a better payout.

In other word, the hippocampus lets you learn, process the moment of objects through space (spatial reasoning) and helps you suppress your inhibitions–that is, it is directly involved in IQ and Time Preference.

 

So what is the Nucleus Accumbens?

According to Wikipedia:

“As a whole, the nucleus accumbens has a significant role in the cognitive processing of aversion, motivation, pleasure, reward and reinforcement learning;^[5][6][7] hence, it has a significant role in addiction.^[6][7] It plays a lesser role in processing fear (a form of aversion), impulsivity, and the placebo effect.^[8][9][10] It is involved in the encoding of new motor programs as well.^[6] …

Dopaminergic input from the VTA modulate the activity of neurons within the nucleus accumbens. These neurons are activated directly or indirectly by euphoriant drugs (e.g., amphetamine, opiates, etc.) and by participating in rewarding experiences (e.g., sex, music, exercise, etc.).^{[11][12] …}

The shell of the nucleus accumbens is involved in the cognitive processing of motivational salience (wanting) as well as reward perception and positive reinforcement effects.^[6] Particularly important are the effects of drug and naturally rewarding stimuli on the NAc shell because these effects are related to addiction.^[6] Addictive drugs have a larger effect on dopamine release in the shell than in the core.^[6] The specific subset of ventral tegmental area projection neurons that synapse onto the D1-type medium spiny neurons in the shell are responsible for the immediate perception of the rewarding property of a stimulus (e.g., drug reward).^{[3][4] …}

The nucleus accumbens core is involved in the cognitive processing of motor function related to reward and reinforcement.^[6] Specifically, the core encodes new motor programs which facilitate the acquisition of a given reward in the future.^[6]

So it sounds to me like the point of the nucleus accumbens is to learn “That was awesome! Let’s do it again!” or “That was bad! Let’s not do it again!”

Together, the nucleus accumbens + hippocampus can learn “4 sugar cubes in a few seconds is way better than 1 sugar cube right now.” Apart, the nucleus accumbens just says, “Sugar cubes! Sugar cubes! Sugar cubes!” and jams the lever that says “Sugar cube right now!” and there is nothing the hippocampus can do about it.

 

What distinguishes humans from all other animals? Our big brains, intellects, or impressive vocabularies?

It is our ability to acquire new knowledge and use it to plan and build complex, multi-generational societies.

Ants and bees live in complex societies, but they do not plan them. Monkeys, dolphins, squirrels, and even rats can plan for the future, but only humans plan and build cities.

Even the hunter-gatherer must plan for the future; a small tendril only a few inches high is noted during the wet season, then returned to in the dry, when it is little more than a withered stem, and the water-storing root beneath it harvested. The farmer facing winter stores up grain and wood; the city engineer plans a water and sewer system large enough to handle the next hundred years’ projected growth.

All of these activities require the interaction between the hippocampus and nucleus accumbens. The nucleus accumbens tells us that water is good, grain is tasty, fire is warm, and that clean drinking water and flushable toilets are awesome. The hippocampus reminds us that the dry season is coming, and so we should save–and remember–that root until we need it. It reminds us that we will be cold and hungry in winter if we don’t save our grain and spend a hours and hours chopping wood right now. It reminds us that not only is it good to organize the city so that everyone can have clean drinking water and flushable toilets right now, but that we should also make sure the system will keep working even as new people enter the city over time.

Disconnect these two, and your ability to plan goes down the drain. You eat all of your roots now, devour your seed corn, refuse to chop wood, and say, well, yes, running water would be nice, but that would require so much planning.

 

As I have mentioned before, I think Europeans (and probably a few other groups whose history I’m just not as familiar with and so I cannot comment on) IQ increased quite a bit in the past thousand years or so, and not just because the Catholic Church banned cousin marriage. During this time, manorialism became a big deal throughout Western Europe, and the people who exhibited good impulse control, worked hard, delayed gratification, and were able to accurately calculate the long-term effects of their actions tended to succeed (that is, have lots of children) and pass on their clever traits to their children. I suspect that selective pressure for “be a good manorial employee” was particularly strong in German, (and possibly Japan, now that I think about it,) resulting in the Germanic rigidity that makes them such good engineers.

Nothing in the manorial environment directly selected for engineering ability, higher math, large vocabularies, or really anything that we mean when we normally talk about IQ. But I do expect manorial life to select for those who could control their impulses and plan for the future, resulting in a run-away effect of increasingly clever people constructing increasingly complex societies in which people had to be increasingly good at dealing with complexity and planning to survive.

Ultimately, I see pure mathematical ability as a side effect of being able to accurately predict the effects of one’s actions and plan for the future (eg, “It will be an extra long winter, so I will need extra bushels of corn,”) and the ability to plan for the future as a side effect of being able to accurately represent the path of objects through space and remember lessons one has learned. All of these things, ultimately, are the same operations, just oriented differently through the space-time continuum.

Since your brain is, of course, built from the same DNA code as the rest of you, we would expect brain functions to have some amount of genetic heritablity, which is exactly what we find:

Source: The Heritability of Impulse Control, Genetic and environmental influences on impulsivity: a meta-analysis of twin, family and adoption studies

“A meta-analysis of twin, family and adoption studies was conducted to estimate the magnitude of genetic and environmental influences on impulsivity. The best fitting model for 41 key studies (58 independent samples from 14 month old infants to adults; N=27,147) included equal proportions of variance due to genetic (0.50) and non-shared environmental (0.50) influences, with genetic effects being both additive (0.38) and non-additive (0.12). Shared environmental effects were unimportant in explaining individual differences in impulsivity. Age, sex, and study design (twin vs. adoption) were all significant moderators of the magnitude of genetic and environmental influences on impulsivity. The relative contribution of genetic effects (broad sense heritability) and unique environmental effects were also found to be important throughout development from childhood to adulthood. Total genetic effects were found to be important for all ages, but appeared to be strongest in children. Analyses also demonstrated that genetic effects appeared to be stronger in males than in females.”

 

“Shared environmental effects” in a study like this means “the environment you and your siblings grew up in, like your household and school.” In this case, shared effects were unimportant–that means that parenting had no effect on the impulsivity of adopted children raised together in the same household. Non-shared environmental influences are basically random–you bumped your head as a kid, your mom drank during pregnancy, you were really hungry or pissed off during the test, etc., and maybe even cultural norms.

So your ability to plan for the future appears to be part genetic, and part random luck.

Happy 200 Posts! Come join the party

It’s a sedate party, I admit. But the canapes are delish.

There are two themes to this fairly open thread: How I Came to Be Me and Your Favorite Posts

It’s funny, but way back when I began typing little theories about human behavior into my graphing calculator during highschool math, I had no idea that the whole topic matter was taboo. Actually, I didn’t even believe in evolution back then–at least, I was pretty sure that evolution was a thing that Christians were not supposed to believe in. Nebraska Man and all that, you know. So I didn’t think of my theories as having anything to do with evolution, just “things that made sense.”

I remember one of them, on the symbolic/physical importance of sharing food among friends. For me to take some of my food and give it to you both helps ensure your continued existence, and decreases my my chances of existing. To give a friend a french fry or cookie from one’s own lunch tray was a sign of valuing the friend’s life enough to be willing to risk a threat to one’s own life to help the friend. This was the symbolism, I wrote, underneath both the importance of ritual food sharing with strangers–bread and salt in Russia, the inviting of people to tea or dinner–and more elevatedly, Eucharistic communion itself: the giving of Christ’s literal life, blood and body in the breaking of bread and giving of it to his disciples, ensuring their lives continued by ending his own.

Years later, when highschool days had largely faded from my mind, I was reminded rather vividly of this essay when a new Jewish friend promptly escorted me to their home and set out a kosher dinner, a good portion of which was bread.

Since this is my party, help yourself to the metaphorical bread and salt, wine and cheese. Or coffee, if you prefer.

But back to our story. I somehow passed highschool bio and got into college, despite being more or less a Creationist, where I did all of the normal college things. Alas, college is wasted on the young. Eventually I read a book on human evolution and decided that the book sounded a lot more sensible than that anti-evolution video they’d shown us once in Sunday School. The last chapter of the book–sadly, I no longer remember the title–wasn’t about bones and teeth and people trying to figure out which skeletons were hoaxes, but the evolution of human families in which grandparents exist. Now, sure, all that business about australopithecines sounded reasonable enough, but that last chapter blew me away: a complex emergent behavior / idea-thing like a family could also have been created by evolutionary adaptation.

At the time, I considered myself a liberal of the most upstanding character. I did all of the good liberal things–feminist, pro-trans, fat acceptance, LGBQ friendly, Pagan friendly, anti-war, anti-meat, anti-racism, anarchist, etc.

Then came Facebook and similar systems. Since I like debating politics, I tried to write entertaining essays for my friends, and promptly lost most of my friends. I also got kicked out of my feminist community for some trivial bullshit–I think I posted a response to another poster in the wrong section of a message board.

Now, I am not stranger to internet flame wars, but by this time, the whole business was starting to grate. Friends who were basically on the same side of the political system ought to be able to discuss political details without antagonism or declaring that the other person is secretly evil. At the very least, there ought to be some trust that your friends have good hearts and are trying hard. But I lacked some of the meta-level understanding of what was going on in liberalism necessary to safely traverse these waters–for example, I thought pretty much all liberals accepted evolution as true. It turns out that they only believe in evolution when conservatives are around. Among themselves, they deny that humans have “instincts” or that gender exists, and insist that the application of evolutionary theory to the study of human behavior is actually evil.

Then something major happened: I had a kid.

I lost friends over that, too, but I realized several important things:

1. Childbirth is absolutely horrific.
2. There is no possible way the differences in the amount of energy/risk men and women entail to reproduce could not cause different evolutionary pressures that would lead to different optimal mating strategies.
3. Feminist claims that parents teach their children gender roles are total bullshit.
4. Gender is mostly nature, not nurture.
5. Natural childbirth is a horrible idea (for the record, c-sections are also horrible and the recovery is worse.)
6. People politicize a bunch of issues that should not be politicized.

Something non-political also happened: the baby got sick. After a week of especially sleepless nights, I figured out what was wrong and how to fix it. I remember that moment, the sudden energy that came over me: NO ONE was going to stand between me and helping my child.

When feminists speak of “empowering” women, this is the feeling they mean. The feeling that you will do whatever the hell it takes to accomplish your objectives, and no one and nothing will stop you. I don’t think you can “empower” someone. It comes from within. It comes from the evolutionary urge to protect your children.

As it turned out, no one got in my way and everyone was actually super-helpful and the whole business ended well, with a happy, healthy child. Luckily my husband is an upstanding fellow who loves his children, too. But helpfulness is not one of life’s givens.

Around this time, the whole SJW movement was picking up steam, and the “privilege” concept became an unexpected sticking point. I thought the idea was basically nonsense, and said so. I later came across a conversation between–I thought–a friend and one of my best friends. “EvolutionistX isn’t worth talking to,” said the best friend.

I didn’t break up with liberalism. Liberalism broke up with me.

It had become increasingly obvious to me that the people in these feminist and SJW communities weren’t just wrong on a few issues, but that many of them were deeply psychologically disturbed, and the politics had become a cover/excuse/justification for not getting help and dealing with their issues. Many of them, to be frank, were disconnected from reality, and pointing out that physical facts contradicted them (I don’t mean totally controversial theories like evolution, but just basic stuff,) resulted in anything from banning to death threats. Unfortunately, the memeplex was becoming increasingly dominant, infecting communities that had nothing to do with politics and were officially apolitical.

By this point, I’d learned to just keep my mouth shut, and found some new things to do with my time. My husband introduced me to Jayman’s blog, and I read every word of it. Same for Evo and Proud, the sadly defunct Neuropolitics, and West Hunter. These guys are awesome. I learned so much anthropology I hadn’t learned in anthropology class, without the post-modern bullshit and constant negativity that had infected academia. I was still vaguely afraid of talking, but at least I had some good reading material.

Shortly after, I beheld, with terrifying clarity, the abyss. Suddenly I understood why liberals hate HBD and ev psych.

My break with the left came over an obscure case: protests surrounding the death of Marshall Coulter, a teenager who climbed over a homeowner’s 6-foot fence at 2 am and then got shot in the head.

The elites will always defend the bullies.

Now, I understand that there are some innocent excuses for being in someone’s yard at 2 am, like being so drunk that you think you’re at your own home when you aren’t, or jumping a fence for a dare, with no intention of committing any harm. But it remains, like driving 120 miles per hour or poking bears, an activity that I regard has having a very high chance of killing you, and you should not do if you do not accept those risks. You certainly do not blame the bear for eating you after you poke it.

Likewise, if you act like you are breaking into someone’s house in the middle of the night, the natural and only reasonable consequence is that home owner (or resident) kills you.

Salon weighed in, with an article about what a sweet kid Marshall was.

Protestors weighed in, claiming that Marshall was just an innocent kid who hadn’t done anything wrong and didn’t deserve to die, demanding that the homeowner (who was being charged with attempted murder) be, well, charged with attempted murder.

In fact, Marshall already had a criminal past before he got shot in 2014:

• October 2009: disturbing the peace
• November 2012: criminal trespassing
• December 2012: disturbing the peace
• December 2012: burglary of an inhabited dwelling
• March 2013: possession of stolen things and theft
• April 2013: possession of marijuana

Ironically, the police had actually been discussing Marshall as a possible suspect in a string of recent burglaries the day before he was shot trying to burglarize someone’s house.

The attempted homicide charges were only dropped against the homeowner because Marshall recovered enough from the bullet in his head to get arrested for three more crimes:

During the Trayvon Martin case, I had understood how someone could hear the story of a teenager walking home with a pack of Skittles and think that a great injustice had been done. This case had no such ambiguities. I realized the left had abandoned liberalism, in every traditional sense of the word. This was not about freedom; this was an explicit denial of the right of self-defense against someone intent on harming you, at least if you were white and they were black.

Every betrayal suddenly made sense. The meta-politics became clear. I felt like I finally understood everything, and I leapt into the abyss.

Around this time, my husband found Moldbug’s Open Letter to Open-Minded Progressives, and I wandered into Slate Star Codex. All of the words I’d been holding in began spilling out, in a torrent, so I made this blog.

A friend of mine (if you’re reading this, hi!) had kept telling me that life is too short to worry about assholes. If I had to walk on eggshells around my other “friends,” then they weren’t my friends and I should get new friends.

Sage advice.

So here we are, 200 posts in, and people actually like my blog.

Thanks for reading, guys. I hope you like the next 200 posts.

 

I’m going to open up the floor. Tell me your stories, ask questions, or just chat. And if you feel like it, tell me your favorite posts for inclusion in the sidebar.

Women in Combat

“The US Marines Tested Mixed-Gender Squads Against all Male ones, and the Results are Pretty Bleak”

I will be writing a full post about this soon, but since I already have a month+ backlog, it’s going to be a while before it shows up here. Nevertheless, I think this is an important enough study that I want to bring your attention to it now. A few quotes:

“All branches of the military are facing a January 1, 2016, deadline to open all combat roles to women. …

“All-male squads, teams and crews and gender-integrated squads, teams, and crews had a noticeable difference in their performance of the basic combat tasks of negotiating obstacles and evacuating casualties. For example, when negotiating the wall obstacle, male Marines threw their packs to the top of the wall, whereas female Marines required regular assistance in getting their packs to the top. During casualty evacuation assessments, there were notable differences in execution times between all-male and gender-integrated groups, except in the case where teams conducted a casualty evacuation as a one-Marine fireman’s carry of another (in which case it was most often a male Marine who “evacuated” the casualty.)

“The report also says that female Marines had higher rates of injury throughout the experiment. …

“A military unit at maximum combat effectiveness is a military unit least likely to suffer casualties. Winning in war is often only a matter of inches, and unnecessary distraction or any dilution of the combat effectiveness puts the mission and lives in jeopardy. Risking the lives of a military unit in combat to provide career opportunities or accommodate the personal desires or interests of an individual, or group of individuals, is more than bad military judgment. It is morally wrong.”
