in a brief article on the church’s role in the development of things like political liberty (belated happy magna carta day, btw!) and prosperity in medieval england, ed west says:

“Last week I was writing about Magna Carta and how the Catholic Church’s role has been written out, in particular the part of the Archbishop of Canterbury, Stephen Langton.

“But the same could also be said about much of English history from 600AD to 1600; from the very first law code written in English, which begins with a clause protecting Church property, to the intellectual flourishing of the 13th century, led by churchmen such as Roger Bacon, the Franciscan friar who foresaw air travel.

“However, the whitewashing of English Catholic history is mainly seen in three areas: political liberty, economic prosperity and literacy, all of which are seen as being linked to Protestantism.

“Yet not only was Magna Carta overseen by churchmen, but Parliament was created by religious Catholics, including its de facto founder, Simon de Montfort….

“Likewise literacy, which hugely increased in the 16th century and is often attributed to the Protestant attachment to the word, was already increasing in the 15th and the rate of growth did not change after Henry VIII made the break with Rome….”

here’s the graph from max roser on literacy rates in western europe from the fifteenth century onwards [click on chart for LARGER view]:


and more from ed west:

“As for the economy and the ‘Protestant work ethic’, well the English economy was already ‘Protestant’ long before the Reformation.

As one study puts it:

“‘By 1200 Western Europe has a GDP per capita higher than most parts of the world, but (with two exceptions) by 1500 this number stops increasing. In both data sets the two exceptions are Netherlands and Great Britain. These North Sea economies experienced sustained GDP per capita growth for six straight centuries. The North Sea begins to diverge from the rest of Europe long before the “West” begins its more famous split from “the rest”. [W]e can pin point the beginning of this “little divergence” with greater detail. In 1348 Holland’s GDP per capita was $876. England’s was $777. In less than 60 years time Holland’s jumps to $1,245 and England’s to 1090. The North Sea’s revolutionary divergence started at this time.’

“In fact GDP per capita in England actually decreased under the Tudors, and would not match its pre-Reformation levels until the late 17th century.”

so there are three big things — political liberty, prosperity, and literacy — all of which improved significantly, or began on a trajectory to do so, already by the high middle ages in northwestern or “core” europe (england, netherlands, nw france, ne germany, scandinavia, etc.).

there are additionally some other large and profound societal changes that occurred in core europe which also started earlier than most people think:

– a marked reduction in homicide rates, which has been studied extensively by historians of crime like manuel eisner, was written about at great length by steven pinker in his Better Angels, and most recently was suggested by peter frost and henry harpending to be the result of genetic pacification via the execution of criminals in the middle ages (i think they’re partly/mostly right!).

here’s the example of england (from eisner 2001):

eisner - homicide rates in england

“In the thirteenth and fourteenth century, the mean of almost 40 different estimates lies around 24 homicides per 100,000. The average homicide rates are higher for the late fourteenth century than for the thirteenth century, but it seems impossible to say whether this is due to the difference of the sources used or reflects a real increase related to the social and economic crises in the late Middle Ages. When estimate start again after a gap of some 150 years, the average calculated homicide rates are considerably lower with typical values of between 3-9 per 100,000. From then onwards, the data for Kent line up with surprising precision along a straight line that implies a long-term declining trend for more than 350 years.” [pg. 622]

while it is likely that the state’s persistent execution of violent felons over the course of a couple of hundred years in the late medieval/early modern period resulted in the genetic pacification of the english (and other core europeans — this is the frost & harpending proposal), it is also apparent that the frequency of homicides began to drop before the time when the english state became consistent and efficient about its enforcement of the laws (basically the tudor period) — and even before there were many felony offences listed on the books at all. homicide rates went from something like 24 per 100,000 to 3-9 per 100,000 between the 1200s and 1500s, before the state was really effective at law enforcement [pg. 90]:

“As part of their nation-state building the Tudors increased the severity of the law. In the 150 years from the accession of Edward III to the death of Henry VII only six capital statutes were enacted whilst during the next century and a half a further 30 were passed.”

the marked decline in homicides beginning in the high middle ages — well before the early modern period — needs also to be explained. you know what i think: core europeans were at least partly pacified early on by the selection pressures created by two major social factors present in the medieval period — outbreeding and manorialism.

– the rise of the individual, which began in northwest europe at the earliest probably around 1050. yes, there was a rather strong sense of the individual in ancient greece (esp. athens), but that probably came and went along with the guilt culture (pretty sure these things are connected: individualism-guilt culture and collectivism-shame culture). and, yes, individualism was also strong in roman society, but it seems to have waned in modern italy (probably more in the south than in the north, and possibly after the italian renaissance in the north?). siendentorp rightly (imho) claims that it was the church that fostered the individualism we find in modern europe, but not, i think, in the way that he believes. individualism can come and go depending, again i think, on mating patterns, and the mating patterns in northwest europe did not shift in the right direction (toward outbreeding) until ca. the 700-800s (or thereabouts) thanks to the church, so individualism didn’t begin to appear in that part of the world until after a few hundred years (a dozen-ish generations?) or so of outbreeding.

in any case, the earliest appearances of individualistic thinking pop up in nw europe ca. 1050, which is quite a bit earlier than a lot of people imagine, i suspect.

– the disappearance of and dependence upon the extended family — the best evidence of this of which i am aware comes from medieval england. the early anglo-saxons (and, indeed, the britons) had a society based upon extended families — specifically kindreds. this shifted beginning in the early 900s and was pretty complete by the 1100s as evidenced by the fact that members of the kindred (i.e. relatives) were replaced by friends and colleagues (i.e. the gegilden) when it came to settling feuds. (see this previous post for details: the importance of the kindred in anglo-saxon society.)

the usual explanation offered up for why the societies in places like iraq or syria are based upon the extended family is that these places lack a strong state, and so the people “fall back” on their families. this is not what happened in core europe — at least not in england. the importance of the extended family began to fall away before the appearance of a strong, centralized state (in the 900s). in any case, the argument is nonsensical. the chinese have had strong, centralized states for millennia, and yet the extended family remains of paramount importance in that society.

even in the description of siedentorp’s Inventing the Individual we read: “Inventing the Individual tells how a new, equal social role, the individual, arose and gradually displaced the claims of family, tribe, and caste as the basis of social organization.” no! this is more upside-down-and-backwardness. it’s putting the cart before the horse. individualism didn’t arise and displace the extended family — the extended family receded (beginning in the 900s) and then the importance of the individual came to the fore (ca. 1050).

there are a lot of carts before horses out there, which makes it difficult to get anywhere: the protestant work ethic didn’t result in economic prosperity — a work ethic was selected for in the population first and, for various reasons, this population then moved toward even more protestant ideas and ways of thinking (and, voila! — the reformation. and the radical reformation as a reaction to that.) a strong state did not get the ball rolling in the reduction in violence in nw europe or lead to the abandonment of the extended family — levels of violence began to decline before the state got heavily involved in meting out justice AND the extended family disappeared (in northern europe) before the strong state was in place. and so on and so forth.

it’s very hard for people to truly understand one another. (this goes for me, too. i’m no exception in this case.) and, for some reason, it seems to be especially hard for people to understand how humans and their societies change. i suppose because most people don’t consider evolution or human biodiversity to be important, when in fact they are ALL important! in coming up with explanations for why such-and-such a change took place, the tendency is to look at the resultant situation in our own society — eg. now the state is important rather than the extended family, which is what used to be important — and to then assume that the thing characteristic of the present (the state in this example) must’ve been the cause of the change. i don’t know what sort of logical fallacy that is, but if it doesn’t have a name, i say we call it the cart-horse fallacy! (alternative proposal: the upside-down-and-backwards fallacy.) explaining how changes happened in the past based on the present state of affairs is just…wrong.

so, a lot of major changes happened in core european societies much earlier than most people suppose and in the opposite order (or for the opposite reason) that many presume.

also, and these are just a couple of random thoughts, the protestant reformation happened in the “core” of core europe; the radical reformation (a set of reactionary movements to the main reformation) and the counter reformation (the more obvious reactionary movement to the reformation) happened in peripheral europe. the enlightenment happened in the “core” of core europe; the romantic movement, in reaction to the enlightenment, happened in peripheral europe (or peripheral areas of core countries, like the lake district in england, etc.). just some thoughts i’ve been mulling over in my sick bed. =/

northern europeans began to think of — or at least write about — themselves as individuals beginning in the eleventh century a.d. [pgs. 158, 160, and 64-67 – bolding and links inserted by me]:

The discovery of the individual was one of the most important cultural [*ahem*] developments in the years between 1050 and 1200. It was not confined to any one group of thinkers. Its central features may be found in different circles: a concern with self-discovery; an interest in the relations between people, and in the role of the individual within society; an assessment of people by their inner intentions rather than by their external acts. These concerns were, moreover, conscious and deliberate. ‘Know yourself’ was one of the most frequently quoted injunctions. The phenomenon which we have been studying was found in some measure in every part of urbane and intelligent society.

“It remains to ask how much this movement contributed to the emergence of the distinctively Western view of the individual…. The continuous history of several art-forms and fields of study, which are particularly concerned with the individual, began at this time: auto-biography, psychology, the personal portrait, and satire were among them….

“The years between 1050 and 1200 must be seen…as a turning-point in the history of Christian devotion. There developed a new pattern of interior piety, with a growing sensitivity, marked by personal love for the crucified Lord and an easy and free-flowing meditation on the life and passion of Christ….

“The word ‘individual’ did not, in the twelfth century, have the same meaning as it does today. The nearest equivalents were *individuum*, *individualis*, and *singularis*, but these terms belonged to logic rather than to human relations….

“The age had, however, other words to express its interest in personality. We hear a great deal of ‘the self’, not expressed indeed in that abstract way, but in such terms as ‘knowing oneself’, ‘descending into oneself’, or ‘considering oneself’. Another common term was *anima*, which was used, ambiguously in our eyes, for both the spiritual identity (‘soul’) of a man and his directing intelligence (‘mind’). Yet another was ‘the inner man’, a phrase found in Otloh of Saint Emmeram and Guibert of Nogent, who spoke also of the ‘inner mystery’. Their vocabulary, while it was not the same as ours, was therefore rich in terms suited to express the ideas of self-discovery and self-exploration.

“Know Yourself

“Self-knowledge was one of the dominant themes of the age…. These writers all insisted on self-knowledge as fundamental. Thus Bernard wrote to Pope Eugenius, a fellow-Cistercian, about 1150: ‘Begin by considering yourself — no, rather, end by that….For you, you are the first; you are also the last.’ So did Aelred of Rievaulx: ‘How much does a man know, if he does not know himself?’ The Cistercian school was not the only one to attach such a value to self-knowledge. About 1108 Guibert of Nogent began his history of the Crusade with a modern-sounding reflection about the difficulty of determining motive:

“‘It is hardly surprising if we make mistakes in narrating the actions of other people, when we cannot express in words even our own thoughts and deeds; in fact, we can hardly sort them out in our own minds. It is useless to talk about intentions, which, as we know, are often so concealed as scarcely to be discernible to the understanding of the inner man.’

“Self-knowledge, then, was a generally popular ideal.”

there seem to be two broad sociobiological/genocultural packages when it comes to average nepotistic vs. not-so-nepotistic altruistic behaviors in human populations — these are not binary opposites, but rather the ends of some sort of continuum of behavioral traits [click on table for LARGER view]:

nepotistic vs. not-so-nepotistic

the common thread running through the not-so-nepotistic groups of today (primarily northwest europeans) is a long history of outbreeding (i.e. avoiding close matings, like cousin marriage). (and a long history of manorialism. yes, i WILL start my series on medieval manorialism soon!) while individualism and guilt cultures may have been present in northern europe in paleolithic or even mesolithic populations, these behavioral traits and mindsets were definitely not present in the pre-christian germanic, british, or irish populations of late antiquity. those populations were very much all about clans and kindreds, feuding and honor, shame, and group consensus. guilt/individualistic cultures (i.e. not-so-nepostic societies) can come and go depending at least partly on long-term mating patterns. human evolution can be recent as well as aeons old.

the individualistic guilt-culture of northwest (“core”) europeans today came into existence thanks to their extensive outbreeding during the medieval period (…and the manorialism). the outbreeding started in earnest in the 800s (at least in northern france) and, as we saw above, by 1050-1100 thoughts on individualis began to stir. around the same time, communes appeared in northern italy and parts of france — civic societies. violence rates begin to fall in the 1200s, especially in more outbred populations, i would argue (guess!) because the impulsive violence related to clan feuding was no longer being selected for.

by the 1300-1400s, after an additional couple hundred years of outbreeding, the renaissance was in full swing due to the “wikification” of northern european society — i.e. that nw europeans now possessed a set of behavioral traits that drove them to work cooperatively with non-relatives — to share openly knowledge and ideas and labor in reciprocally altruistic ways. the enlightenment? well, that was just the full flowering of The Outbreeding Project — an explosion of these not-so-nepotistic behavioral traits that had been selected for over the preceding 800 to 900 years. individualism? universalism? liberal democracy? tolerance? reason? skepticism? coffeehouses? the age of enlightenment IS what core europeans are all about! hurray! (^_^) the Project and its effects are ongoing today.

it could be argued that the fact that certain mating patterns seem to go together with certain societal types is just a coincidence — or that it’s the societal type that affects or dictates the mating patterns. for example, i said in my recent post on shame and guilt in ancient greece that:

“shame cultures are all tied up with honor — especially family honor. japan — with its meiwaku and seppuku — is the classic example of a shame culture, but china with its confucian filial piety is not far behind. the arabized populations are definitely shame cultures with their honor killings and all their talk of respect. even european mediterranean societies are arguably more honor-shame cultures than guilt cultures [pdf].

“if you’ve been reading this blog for any amount of time, you’ll recognize all of those shame cultures as having had long histories of inbreeding: maternal cousin marriage was traditionally very common in east asia (here’re japan and china); paternal cousin marriage is still going strong in the arabized world; and cousin marriage was prevelant in the mediterranean up until very recently (here’s italy, for example).”

perhaps, you say, the causal direction is that nepotistic, clannish shame-cultures somehow promote close matings (cousin marriage or whatever). well, undoubtedly there are reinforcing feedback loops here, but the upshot is that both ancient greece and medieval-modern europe clearly illustrate that the mating patterns come first. (possibly ancient rome, too, but i’ll come back to that another day.) the pre-christian northern european societies were clannish shame-cultures until after the populations switched to outbreeding (avoiding cousin marriage) in the early medieval period. late archaic-early classical greek society was rather (a bit borderline) universalistic, individualistic [pg. 160+] and guilt-based until after they began to marry their cousins with greater frequency (at least in classical athens). the not-so-nepotistic guilt-culture we see now in northwest european populations is particularly resilient, i think, because the outbreeding has been carried out for a particularly long time (since at least the 800s) and thanks to the complementary selection pressures of the medieval manor system (which ancient greece lacked), but it did not exist before the early medieval period.

so, the direction of causation seems to be: (long-term) mating patterns –> societal type (nepotistic vs. not-so-nepotistic).

i think.

Ancient Jomon people not like present-day East Asians“‘We found a unique genetic position of the Jomon people who had diverged before the diversification of most of present-day East Eurasian populations including East Eurasian Islanders.

Uncovering the Genetic History of the Present-Day Greenlandic Population“[W]e analyzed ∼200,000 SNPs from more than 10% of the adult Greenlandic population (n = 4,674). We found that recent gene flow from Europe has had a substantial impact on the population: more than 80% of the Greenlanders have some European ancestry (on average ∼25% of their genome). However, we also found that the amount of recent European gene flow varies across Greenland and is far smaller in the more historically isolated areas in the north and east and in the small villages in the south. Furthermore, we found that there is substantial population structure in the Inuit genetic component of the Greenlanders and that individuals from the east, west, and north can be distinguished from each other. Moreover, the genetic differences in the Inuit ancestry are consistent with a single colonization wave of the island from north to west to south to east. Although it has been speculated that there has been historical admixture between the Norse Vikings who lived in Greenland for a limited period ∼600–1,000 years ago and the Inuit, we found no evidence supporting this hypothesis. Similarly, we found no evidence supporting a previously hypothesized admixture event between the Inuit in East Greenland and the Dorset people, who lived in Greenland before the Inuit.” – h/t razib!

Estimating the genotypic intelligence of populations and assessing the impact of socioeconomic factors and migrations – from davide piffer who tweeted: “New version of my paper with genetic distances. Migrations or drift less likely to explain results.” also, from the paper: “The results also provide preliminary evidence in favor of the hypothesis that poor environmental conditions (i.e. economic and sociocultural) tend to depress national IQ scores. Countries with lower per capita GDP and a lower index of Human Development tended to have larger positive ‘residuals’, that is the difference between the score predicted by the regression (of IQs for developed countries on the 4 SNPs g factor) and the actually measured IQ was larger in countries with lower GDP and HDI (r around 0.7). Thus, poorer and less developed countries have yet to reach their full intellectual potential. The results of this study indicate that the gaps in intellectual performance between some populations can be narrowed via adequate improvement of environmental conditions, however the overall pattern of intellectual scores is due to relatively stable and fixed (genetic) factors and cannot be substantially altered.” – see also terrific post from anatoly karlin on this paper!: Genetics, IQ, and Convergence.

Archaeogenomic insights into the adaptation of plants to the human environment: pushing plant–hominin co-evolution back to the Pliocene“The colonization of the human environment by plants, and the consequent evolution of domesticated forms is increasingly being viewed as a co-evolutionary plant–human process that occurred over a long time period, with evidence for the co-evolutionary relationship between plants and humans reaching ever deeper into the hominin past. This developing view is characterized by a change in emphasis on the drivers of evolution in the case of plants. Rather than individual species being passive recipients of artificial selection pressures and ultimately becoming domesticates, entire plant communities adapted to the human environment.” – h/t george perry!

Are flu shots effective? Your genetics determine how the immune system responds

Environment, more than genetics, shapes immune system“Everyone’s immune system is slightly different—a unique mixture of hundreds of these cells and proteins. But the main driver of this variation is unclear. Although scientists know that our immune system can adapt to our environment—that’s why vaccines work, for instance—it is also built by our genes…. After recruiting 210 identical and fraternal twins between 8 and 82 years old, Davis and colleagues took blood samples and measured more than 200 parameters of their immune systems. For example, they measured the numbers of 95 kinds of immune cells and 51 kinds of proteins. Today, the researchers report online in Cell that identical twins’ immune systems were too different for the variation to boil down to genetics. Indeed, environment overshadowed inheritance in three-quarters of the measurements, and half showed no measurable genetic influence. Moreover, younger twins were more similar than were older twins, evidence that as the twins aged and were exposed to different environments, their immune systems diverged over time.”

Levels of Selection Are Artefacts of Different Fitness Temporal Measures“I show by comparing the fitness of individuals with that of collectives of individuals in the same environment and over the same period of time – as required to decide if one or more levels of selection is acting in a population – that the selection of collectives is a by-product of selection at the individual level; thus, talking about two or more levels of selection represents merely a different perspective on one and the same process.”

Does incidental disgust amplify moral judgment? A meta-analytic review of experimental evidence [pdf] – “We meta-analyzed all available studies, published and unpublished, that experimentally manipulated incidental disgust prior to or concurrent with a moral judgment task (k=50). We found that there is evidence for a small amplification effect of disgust (d=.11), which is strongest for gustatory/olfactory modes of disgust induction. However, there is also some suggestion of publication bias in this literature, and when this is accounted for, the effect disappears entirely (d=-.01). Moreover, prevalent confounds mean that the effect size that we estimate is best interpreted as an upper bound on the size of the amplification effect. The results of this meta-analysis argue against strong claims about the causal role of affect in moral judgment and suggest a need for new, more rigorous research on this topic.” – h/t stuart ritchie!

so, lemme try again this year. topics i plan on blogging about in 2015, not necessarily in this order (and with no guarantees!):

assimilation: “you keep using that word….” (hint: i don’t think assimilation is as easy as most people assume it is. example: the four anglo “folkways” of north america, a la albion’s seed, which STILL haven’t assimilated to one another after 300 to 400 years. and they all originated from the same country/broad cultural background!)

– speaking of assimilation, i’d also like to look at how populations and subpopulations self-sort (egs. the Albion’s Seed populations mentioned above, the American Nations pops discussed at length by jayman on his blog, The Big Sort, etc.) and the significance of that. the migration of populations/subpopulations basically.

manorialism: going to continue (and hopefully complete!) my planned series on the history of manorialism in europe and its different regional types.

– i will also dig in further into the origins of The Outbreeding Project in christian europe. (hint: i think it wuz the romans.)

violence: want to look more into the decline in homicides/impulsive violence in western european populations. last year i wrote a sneak preview of where i think my readings on this are leading, at least for england. we shall see how it pans out.

shame vs. guilt cultures: more on this, too.

the tswana: i’m VERY keen on taking a close look at the tswana of southern africa, because they are the one group outside of the arabized world which has a history of father’s brother’s daughter marriage (see here), but botswana is one of the most successful and functional nations in subsaharan africa. ‘sup with that?!

the french: i have started reading The Discovery of France (thanks to everyone who recommended it!), so i want to discuss the french a bit.

italians: my christmas present to myself was a copy of Making Democracy Work: Civic Traditions in Modern Italy by robert putnam et al., so i want to discuss the italians a bit, too.

democracy: really want to look at the histories/evolution of and differences between liberal and other forms of democracy (like consensus democracy). this is important, i think.

history of mating patterns in various populations: i’ll probably just continue trawling around for more info/data on the historical mating patterns of various populations. it’s what i do.

hbd between individuals (as opposed to between groups): ’cause i think we need to talk about that.

– prolly other stuff, too.

note that i do take reader requests! (especially if i find the topic interesting.) (^_^)

i will also have to find someone who can clone me so that i have the time to do all this blogging! (~_^)

also, my new year’s resolution is to no longer enter into “discussions” with people who feel that the existence of human biodiversity or having an interest in it is somehow wrong or waaaaycist or whatever. that is just a waste of my time. from now on, those people will simply be directed to my what is human biodiversity (hbd)? series.

that is all! (^_^)

here’s a top ten-ish selection of my posts from this year, selected by me (this blog is not a democracy! (~_^) ). they weren’t necessarily the most read or most commented upon posts, but just the ones that i like the best and that i’d like people to read. ymmv!

a BIG thanks to all of you who do read the ol’ blog! and many, many thanks for all the informative and insightful comments. (^_^) …and for some of the crazy comments, too. (~_^)

big summary post on the hajnal line“so, apart from indicating patterns of nuptuality in late medieval and modern europe, hajnal’s line also represents the extent of both manorialism and The Outbreeding Project on the continent. both of these together set up a very new and different sort of social environment for western europeans — a new, and quite unique, social environment which exerted some very different sorts of selection pressures on the populations, particularly on social behaviors, but perhaps on other traits as well.”

medieval manorialism’s selection pressures“medieval society in northern europe (ca. 400-1500 a.d.) produced some quite unique selection pressures which very much shaped the characteristics and personalities of ‘core’ europeans….”

die ostsiedlung“from a sociobiological point-of-view, probably the most underappreciated event in recent western european history. that and the reconquest of spain.”

mating patterns of the medieval franks“by the 800s, second cousin marriages amongst the franks were considered ‘scandalous.’ bishops actively enforced the bans in their dioceses and neighbors willingly squealed on their cousin-marrying neighbors to the bishops. by the 800s-1000s, there is good evidence that both the frankish aristocracy and the lower classes avoided close cousin marriage.” — see also: kindreds, communes, feuds, and mating patterns in medieval france“beginning in the 1000s, there are indications — the rise of lineages and the appearance of communes — that the french kindreds were starting to break apart. however, feuding continued in france into the 1200-1300s, so clannishness did not disappear in france overnight.”

the transition from shame to guilt in anglo-saxon england (and “core” europe)“feelings of guilt were probably selected for over the course of the middle ages in northwestern europe starting in the early part of the period.” — see also: more on the origins of guilt in northwestern european populations“the center of the guilt culture in northwestern europe — the core region which (historically anyway) has been characterized by the least corruption, the highest levels of trust, liberal democracy, free societies, low levels of internal violence, high levels of human accomplishment, the invention of capitalism, the advancement of science, the development of the ideas and ideals of the enlightenment, and pretty much everything else we call western civilization today — is the core where The Outbreeding Project began the earliest in europe.”

sneak preview: violence, punishment, outbreeding, and swashbuckling pirates in medieval england“over the course anglo-saxon period…the death penalty did come to be more widely applied to cases of homicide, but for most of the period there weren’t really very many executions of killers…. more laws demanding the death penalty (or castration) for killings were issued and enforced during the anglo-norman and angevin periods… [but] executions actually remained comparatively low during large parts of the norman period…. as far as i can tell, criminals were executed right and left during the tudor period. the use of capital punishment really ramped up during the 1500s.” — see also: homicide rates in various regions of thirteenth century england“[I]t is possible that every person in England in the thirteenth century, if he did not personally witness a murder, knew or knew of someone who had been killed.”

a study in swiss“my guess is that the swiss are some of western europe’s ‘inbetweeners’ as far as outbreeding goes. i guessed that they probably got involved in The Outbreeding Project later than some other western europeans — the ones in and closer to the center of my ‘core’ europe. and they didn’t experience manorialism either (unless some of them on the swiss plateau did?).”

reverse renaissance?“perhaps the arabized world underwent a *reverse* renaissance process thanks to the introduction by the arabs of the most inbred form of cousin marriage — father’s brother’s daughter (fbd) marriage — to the populations of the middle east/maghreb….” — see also asabiyyah and asabiyyah ii – clannishness and the abbasid caliphate.

fbd cousin marriage and clans and tribes in iraq“i think a long term inbreeding society selects — or *can* select — for what i call clannishness. and iraqis have got that in spades. they’ve got clans and tribes, nepotism, and an obvious inability to handle liberal democracy. not that that’s some sort of goal in and of itself. i’m just sayin’.”

cousin marriage in sub-saharan africa“there is also a wide variety of mating patterns in ss africa. some populations avoid cousin marriage altogether. we’ve already seen this with the bamileke of cameroon and the igbo of nigeria. also the turkana of kenya and quite possibly the amhara of ethiopia (not 100% sure about them — need to double-check). a notable group which apparently avoids cousin marriage is the zulu. but plenty of other ss africa groups do practice cousin marriage like, as you’ll see in the table below, the kongo and luba in the democratic republic of congo, the ashanti in ghana, the sotho-tswana in south africa, and the kpelle of liberia.” — see also: the bamileke of cameroon and fulani, hausa, igbo, and yoruba mating patterns.

the american revolutions“that there were four american revolutions is a result of the fact that four (five?) somewhat different english populations settled in different regions of north america. the cultural and attitudinal differences between these regions persist to this day because, undoubtedly, there are genetic variations between the populations — probably average genetic differences in the frequencies of genes related to behaviors, personality, and even intelligence. these regional differences also persist because, since the very founding of the united states, like-minded people have been self-sorting themselves within the country so that they group together — and that sorting process has *not* been slowing down.”

it’s not nature and nurture…“…it’s nature and…*we dunno*…miscellaneous/unknown/noise?” — this post's actually very important. READ THIS POST! think about it for a while and let it sink in. and make sure to follow the links!

“every society selects for something.” — greg cochran

every society selects for something. it does take some time for selection pressures to make a difference when it comes to the frequencies of “genes for” various behavioral traits, of course (unless the culling is extreme): twenty generations, maybe. forty is probably better. a few hundred? yeah, that’ll definitely do it. the point is, it doesn’t necessarily take millions of years for evolution by natural selection to work. not even tens of thousands. we don’t have to cast the net back to the paleolithic or even the mesolithic in our search for the origins of behavioral traits in human populations (although the roots for many of them are probably there…or even farther back to our common origin with other apes and even other social mammals, lizards, fruit flies, tomatoes etc., etc.) — we can and should look for selection pressures in more recent eras, too. and “the environment” that exerts these pressures on human populations is not just the natural world — it’s our social worlds, too.

this will be the first in a series of posts on manorialism in medieval europe, because i think that it’s incumbent upon every blogger to bore their readers to tears medieval society in northern europe (ca. 400-1500 a.d.) produced some quite unique selection pressures which very much shaped the characteristics and personalities of “core” europeans, i.e. the dutch (minus the frisians), the belgians, the french (especially the northeastern french), the english (especially the southeastern english), to some degree the lowland scots, the germans (especially those to the west), the scandinavians (especially those further south), the northern italians (especially those from the north italian plain), the northern spanish (especially catalonians), and to some degree the swiss. one of those selection pressures was, of course, europe’s Outbreeding Project, which i never shut up about. (sorry!) the other big one, i think, was manorialism — a communal agricultural system that was really an almost all-encompassing socio-religious-political system which, although its features and importance did vary at different times and in different locales, pretty much regulated nearly all aspects of medieval europeans’ lives. where it existed — a key point which i’ll come back to later.

the working theory around here is that the Outbreeding Project set up the selection pressures for getting rid of much of what we could call “nepotistic altruism” in core europe, allowing for greater cooperation and trust between unrelated individuals and, therefore, a more open and “corporate” sort of society. a second working theory is that manorialism set up selection pressures for a whole suite of traits including perhaps: slow life histories; future time orientation; delayed gratification; the good ol’ protestant work ethic; a general compliant nature and even rather strong tendencies toward conformity; perhaps even a high degree of gullibility; perhaps a few extra iq points; and even more cooperation and trust between unrelated individuals. or not. please keep in mind that i’m just thinking out loud in these posts. oh — the manor system also probably contributed to the selection for the reduction in impulsive violence. (i’ll be exploring more fully the various aspects of manorialism that i think may have created the selection pressures for these various traits in the coming posts — promise! just giving you a rough outline now.) the Outbreeding Project and manorialism very much went hand-in-hand as well — the medieval european manor system could not have happened without all of the outbreeding, and the Outbreeding Project was reinforced by the manor system (since marriage was often regulated within the manor system).

manorialism — “classic,” bipartite manorialism (more on that below) — started with the franks in austrasia by at least the 600s or perhaps earlier and spread gradually southwards with the frankish conquest of, well, france and eastwards during the ostsiedlung. we find it just across the channel in southern england very early as well — there are references to what sounds like features of a manor system in the laws of king ine of wessex (688-726) [see mitterauer, pg. 43]. the medieval european manor system originated, then, roughly in the area outlined in green below (yes — this is the very same area where the Outbreeding Project began. which is convenient, really, ’cause i like not having to make multiple maps! in case you’re new here, the other lines on the map indicate the hajnal line.):

hajnal line - core europe

interestingly, the frisians, although quite centrally located on the coast of the netherlands in this core region, never experienced manorialism. mitterauer ties manorialism to cereal agriculture and the new agricultural techniques developed in the early medieval period (with the introduction of the heavy plow, etc.), so areas unsuitable for such farming — like mountainous regions or swampy areas — typically simply did not see the introduction of the classic manor system.

classic manorialism was introduced to southern france (but bypassed some more remote areas like the massif central) as those regions were conquered by the merovingians and carolingians between the fifth and eighth centuries and to northern spain around the eighth and ninth centuries. the bipartite manor system never reached the southern regions of spain that were controlled by the moors. there was a rudimentary form of manorialism in northern italy even before the area was made a part of the carolingian empire, but the region was heavily manorialized (especially by ecclesiastical monasteries) after charlemagne conquered the lombard kingdom in the 770s. classic, bipartite manorialism was never adopted in central or southern italy or sicily — nowhere in the byzantine world, in fact.

the franks also pushed eastwards, introducing the manor system to central europe, beginning in the eighth century. the border of this eastward movement was, for a couple hundred years or so, the eastern boundary of the carolingian empire (look familiar?). a renewed push eastwards began in the eleventh and twelfth centuries, and a slightly revised form of classic manorialism (a system based upon rents rather than work exchange) was introduced to areas/populations further to the east in central-/eastern-europe including the baltics, large parts of poland, bohemia, moravia, parts of slovakia, western hungary, and slovenia. quite obviously, these populations experienced manorialism for a shorter time than those to the west.

the “classic” form of manorialism never reached the farthest parts of eastern europe. eventually, a form of manorialism was adopted in russia and areas of eastern europe bordering russia, but it was quite different than the version western europe had had. this serfdom-heavy manor system in eastern europe also arrived very late compared to manorialism in western europe — in the fifteenth century (iirc) or in some areas even much later. classic manorialism had practically disappeared in western europe by this point.

in scandinavia, denmark was heavily manorialized relatively early i believe (probably around the time of the first wave of the ostsiedlung, although i must check the dates), and manorialism was also very much present southern sweden (scania). the more northerly parts of scandinavia — norway, northern sweden (or sweden north of scania), the swedish-settled areas of finland — didn’t have manors per se, but were covered by a unique version of “manorialism” in which much of the population was under the thumb of the church (and sometimes petty aristocratic landowners). i know my nordic readers are going to object to me saying that, but please wait for the post on manorialism in scandinavia before bombarding me with your counterarguments. thanks! (^_^) this unique form of “manorialism” arrived in northern scandinavia rather late — probably in something like the 1200s (i need to check on that date) — and departed late (the 1800s and even the 1900s in some areas). not sure what happened in the areas of finland not settled by swedes. and i’m pretty sure no form of manorialism ever took hold in iceland, although i reserve the right to be wrong about that. (~_^)

classic manorialism arrived late in ireland — in the late 1200s — and was introduced by the anglo-normans. there was never really much manorialism in wales or the highlands of scotland, although kind david did introduce it to the lowlands of scotland in the 1100s. not sure how well it took hold there, though. i’ll let you know as soon as i do. proper classic manorialism wasn’t really found in cornwall, either, and manors were not very prevalent in east anglia, although there were some.

there was never any manorialism in the balkans.

nor was there ever any classic, bipartite, european-style manorialism in the arabized, islamic world or in china, although there were plenty of large estates in china throughout its history. (don’t know about japan or the korean peninsula.) the difference between medieval european manors and the manors of china has been characterized as a difference between manorialism — which was a sort-of communal agricultural system in which everyone who worked on the manor was a part of a familia — and landlordism, which is what you had in china [pgs. 11-12]:

“In two major works in particular (Hu Rulei 1979; Fu Zhufu 1980), we find sustained analyses of the differences between the socioeconomic structure of imperial China and that of the precapitalist West…. For Hu Rulei, the key lies in the differences between Chinese ‘feudal landlordism’ (*fengjian dizhuzhi*) and European ‘feudal manorialism’ (*fengjian lingzhuzhi*). In the European feudal manor, landownership or economic power was merged with military, administrative, and judicial powers; each manorial lord exercised the entire range of those powers. The state system of manorialism was thus one in which sovereignty was parceled out. In Chinese landlordism, by contrast, political authority came to be separated from economic power through private land-ownership and the frequent buying and selling of land. This made possible the centralized imperial state system. Landlordism and the centralized imperial state thus made up an interdependent politicoeconomic system that must be distinguished from European manorialism. Hu’s is an analytical model that can help explain the differences and hence also their different paths of sociopolitical change in the modern era.

“Fu Zhufu has pointed to another difference between manorialism and landlordism. In the serf-based manorial system, the lord had to look to the subsistence and reproduction of his workers, lest the very basis of the manorial economy be undermined. But the Chinese landlord was under no such constraints. He could seek the highest possible returns that the land-rental market would support (Fu 1980: 9-10, 201-2). Though Fu skirts the issue here, it is obvious that such principles became harshest when the pressures of social stratification were joined by the pressures of population; under those conditions, a tenant who failed to survive could always be replaced by another. Landlordism could become an institutional system in which the poor tenants were pressed below the margins of subsistence.”

which brings me, now, to some of the various characteristics of classic manorialism and the selection pressures that i think they may have exerted.

– the bipartite estate. the bipartite estate was a key aspect of classical (north)western european manorialism. basically, the manor was divided into two parts: the lord’s part — his farm or demesne — and the peasants’ or serfs’ parts — all their individual farms. the serfs or villeins or whatever you want to call them (there were multiple categories of these peasant farmers and a range of names for them) each had farms to work which were granted to them by the lords (keep in mind that sometimes those “lords” were bishops or monks who ran the monasteries). in the earlier part of the medieval period, the serfs owed labor to the lord of the manor as payment — they were obliged to help work the lord’s demesne — but they also independently worked the farms which they were granted, both to sustain themselves and perhaps make a little profit by selling any extra produce to the neighbors or in a market. there were other obligations, too, but the above was the fundamental gist of the whole system. later in the medieval period, the duty to provide labor switched over to a more simple and direct rent system.

also early on in the period, serfs were given (or assigned) farms to work by the lord of the manor. as a young man, you might not be given the same farm that you grew up on — that your parents had worked — especially not if your father/parents were still productive workers. the lord of the manor, or his steward, would just grant you another farm on the manor to work…if there was one available…and if he chose to do so (presumably based on your merit or your familiy’s record). this system eventually changed as well into one in which a son (typically the eldest son) would “inherit” the farm that his father/parents had worked. not sure when this happened. must find out.

not everyone who was a member of a manor operation would be granted a farm to run. some individuals were just laborers on the manor (“cottagers” in england, for example), and there were plenty of domestic servants serving in the manor house, too.

i think that there are potentially selection pressures here for several different traits or qualities. if we ask ourselves, what sort of individual would’ve done best living in this bipartite estate system, i.e. which individuals with which sorts of traits would’ve managed to reproduce the most, i think it might’ve been people with qualities including: being hard-working or industrious — those that made the most of the farm grant and produced the most food to support the most number of kids and even to sell extra produce for a profit; perhaps smarter than some of the neighbors (like the cottagers) — for the same reasons as hard-working; future time oriented — you had to be patient and wait for a farm to become available, or later in the period wait for your father to hand over the farm or die, and not start philandering about the manor before you could afford to raise kids (you also might not be granted a farm, or acquire yourself a husband, if your reputation was ruined beforehand); slow life histories — those individuals who could hold off on reproducing too early would’ve been rewarded with farms, those that did not would’ve been shunned and would lose the opportunity to reproduce further; and compliancy — you didn’t rail (too much) against the man in the manor, and anyone that did wouldn’t have gotten a farm and may have, if they caused too much trouble, been shipped off to a monastery for life (more on that in a later post).

– villikation and familia. villikation is the term that german researchers use when referring to the fact that the manor and all its inhabitants/workers were managed by someone, either by the lord of the manor himself or by a steward who the lord had put in charge of running the place. you would think that, as a serf or tenant farmer on a manor, you wouldn’t want to run afoul of whoever was in charge, and very often those that did were shipped off the manor (to monasteries), so it seems to me that there might’ve been further pressures here to select for compliant and cooperative individuals.

familia was the word used for everyone who was a member of a particular manor! it was a term used especially earlier in the medieval period, but i think it was in usage throughout the entire era (need to double-check that). from mitterauer [pg. 57]:

“On the one hand, there was the villa, the lord’s manor, or the stewards’ manor, with its resident labor force, the members of which were not tied to one another by kinship; on the other hand, there were the farms of the *servi casati*, that is, of the unfree laborers and their dwellings, as well as the *coloni* who were bound to the soil and therefore to a house. Together they formed the *familia*, an overarching household embracing several households.”

a classic (north)western european manor, then, almost sounds like a 1960s hippie kibbutz, at least when it came to the relatedness of the individuals on the estate. (unlike a hippie kibbutz, though, The Man was clearly in charge.) the people living and working on a medieval manor in (north)western europe were not all members of one extended family or clan (which you do see elsewhere, like in eastern europe, especially russia, or southern china). this system, along with the Outbreeding Project, might’ve encouraged the selection for individuals who were willing to cooperate with other (comparatively speaking) unrelated persons. it might even have helped, along with the Outbreeding Project which got rid of much nepotistic altruism imho, to select for highly trusting — and quite highly trustworthy — individuals.

– open-field system. another key feature of (north)western european manorialism was the open-field system in which shares of large “fields” were apportioned out to each family on the manor — each household would get a long strip or strips within one of these huge fields in which to grow their crops. open-field systems were used by the pre-christian germans and slavic populations (iirc), but in those contexts, extended family/kindred/clan members typically shared the fields. again, in the classic manor system, we have more unrelated individuals/families sharing these fields. residents of the manor regularly policed one another, bringing each other to the manorial court if they thought someone was cheating in the open-field system (and also in the usage of the commons), so, again, here we might have the selection for cooperative and trustworthy individuals.

– ecclesiastical manors. i think the presence (or absence) of ecclesiastical manors in any given area might be very important. apparently, ecclesiastical manors exercised more control on their residents, and until later in the period, than those headed by lay lords (more on this in a later post). so, i’d expect all of the behavioral traits associated with manorialism to be even more pronounced in areas/populations that had more than their fair share of ecclesiastical manors: south-central england, france, germany, and northern italy (and northern scandinavia?).

again, these are all just some ideas. Further Research is RequiredTM! would be cool if someone looked through some manor records to see if they could find out which, if any, class of peasants/serfs managed to reproduce more successfully. maybe someone already has?

if/when the “genes for” any or all of the behavioral traits i’ve mentioned here in this post are discovered, my prediction is that the frequencies for them in european populations will be highest in those in the core area and, thanks to the historical origins and spread of manorialism (and the Outbreeding Project), that these frequencies will reduce with distance from that core. again, i reserve the right to be completely and utterly wrong about that. (~_^)

that’s it for now. stay tuned for a bunch of posts on medieval manorialism in the coming weeks! but first, some other business….

Our Futile Efforts to Boost Children’s IQ“How can parenting and socioeconomic status play such minor roles in determining IQ, when scholars on all sides of the nature-nurture debate agree that somewhere around half of the variation in IQ is environmental? The short answer is that the environment that affects IQ doesn’t consist of the advantages that most people have in mind — parents who talk a lot to their toddlers, many books in in the house for the older children, high-quality schools and the like. Instead, studies over the past two decades have consistently found that an amorphous thing called the “nonshared” environment accounts for most (in many studies, nearly all) of the environmentally grounded variation. Scholars are still trying to figure out what features of the nonshared environment are important. Peers? Events in the womb? Accidents? We can be sure only of this: The nonshared environment does not lend itself to policy interventions intended to affect education, parenting, income or family structure.” – from charles murray. – h/t mr. mangan, esq!

The ecology of religious beliefs“Both comparative and experimental evidence indicate that beliefs in moralizing high gods promote cooperation among humans, a behavioral attribute known to correlate with environmental harshness in nonhuman animals. Here we combine fine-grained bioclimatic data with the latest statistical tools from ecology and the social sciences to evaluate the potential effects of environmental forces, language history, and culture on the global distribution of belief in moralizing high gods (n = 583 societies). After simultaneously accounting for potential nonindependence among societies because of shared ancestry and cultural diffusion, we find that these beliefs are more prevalent among societies that inhabit poorer environments and are more prone to ecological duress.”

An extremely low-density human population exterminated New Zealand moa“Here we show that the Polynesian population of New Zealand would not have exceeded 2,000 individuals before extinction of moa populations in the habitable areas of the eastern South Island. During a brief (<150 years) period and at population densities that never exceeded ~0.01 km(-2), Polynesians exterminated viable populations of moa by hunting and removal of habitat. High human population densities are not required in models of megafaunal extinction."
