cpi 2014 - europe

…on twitter, that a chorus of people will respond: oh, just look at the terrible effects communism had on eastern europe! for no good reason really because, as we all know, correlation does not equal causation — although it does “waggle its eyebrows suggestively and gesture furtively while mouthing ‘look over there.'”

just because soviet regimes were present in the past in the same areas of europe where there are high corruption levels today does not mean the one is the cause of the other. (and anyway…look at the regions beyond europe! or southern europe, for that matter.) the relationship is certainly suspicious though, and it wouldn’t be surprising if the two were somehow connected.

one way to try to settle this debate would be to look at pre-soviet corruption rates in eastern europe versus the west to see if the situation was any different beforehand.

i have not done that in this post, in large part because i don’t speak any slavic or other eastern european languages, but primarily because it seemed like way too much work. instead, i’m going to take a look a civicness, a set of behaviors — along with things like intelligence, low amounts of corruption, and low levels of violence — that many researchers reckon are necessary in order to have western-style liberal democracies and economies, if that’s what you want in life. i’ll be focusing on russia, again just to kept this little project manageable. but first, italy.

in Making Democracy Work: Civic Traditions in Modern Italy, robert putnam (yes, that robert putnam) concluded that democracy in northern italy functions better than in the south because the north has had a longer tradition — stretching back to the middle ages — of civicness or of having a civic community. (see previous post: democracy in italy.) according to putnam [pgs. 88-89, 91]:

“Citizenship in the civic community entails equal rights and obligations for all. Such a community is bound together by horizontal relations of reciprocity and cooperation, not by vertical relations of authority and dependency. Citizens interact as equals, not as patrons and clients nor as governors and petitioners….

“Citizens in a civic community, on most accounts, are more than merely active, public-spirited, and equal. Virtuous citizens are helpful, respectful, and trustful towards one another, even when they differ on matters of substance….

“One key indicator of civic sociability must be the vibrancy of associational life.”

in civic societies and civic societies ii, i looked at (self-reported) participation rates in voluntary associations across the world as found in the 2005-2008 wave of the world values survey. specifically, i tallied up the number of individuals who responded that, yes, they were ACTIVE members of the following voluntary associations (thus giving some indication of how civic-minded each of the populations is):

– Church or religious organization
– Sport or recreation organization
– Art, music or educational organization
– Labour union
– Political party
– Environmental organization
– Professional association
– Charitable organization
– Any other voluntary organization

the response rates for eastern europe were abysmal, often vying for last place with the middle east (see previous post for more):

wvs - membership voluntary organizations - totals

not much has changed in the latest wave (2010-2014). here, for example, are the active membership rates for the russian federation for each of the organization types — the first figure is from the 2005-2008 wave, the second from 2010-2014:

– Church or religious organization = 2.60% – 2.00%
– Sport or recreation organization = 5.90% – 2.40%
– Art, music or educational organization = 4.20% – 1.50%
– Labour union = 3.40% – 2.00%
– Political party = 0.80% – 0.50%
– Environmental organization = 0.40% – 0.40%
– Professional association = 1.60% – 1.40%
– Charitable organization = 1.10% – 0.6%
– Any other voluntary organization = n/a – 1.4%

as joseph bradley says in Voluntary Associations in Tsarist Russia: Science, Patriotism, and Civil Society (2009), russia is “not known as a nation of joiners.” apparently not! (mind you, i am not in a position to cast any stones on this account. *ahem*)

but were the russians more civic-minded before the revolution?

unfortunately, i don’t have any figures which can be directly compared to our modern world values surveys, but, yes, there was some amount of participation in voluntary civic institutions in russia in the two hundred years or so preceding 1917. however, civic participation didn’t begin in russia until the mid-1700s (and that is a key point to which i’ll return), and for most of that period, it occurred mostly among the upper classes. participation rates did grow across the nation and classes over the next century and a half, until just after the revolution of 1905 when there was a rapid rise in one sort of voluntary association — consumer cooperatives — among all classes of russians. however, civil society was still comparatively shallow in early-twentieth century russia — it hadn’t fully penetrated the whole of society by that point yet because the concept was so relatively new to the populace. here is laura engelstein in “The Dream of Civil Society in Tsarist Russia: Law, State, and Religion” (2000) quoting the sardinian antonio gramsci on the matter [pg. 23]:

“On the margins of the European state system, sharing but not fully integrating the Western cultural heritage, Russia, it is said, has always lacked just these civic and political traits. Antonio Gramsci provides the classic statement of this contrast: ‘In Russia,’ he wrote in the 1920s, ‘the state was everything, civil society was primordial and gelatinous; in the West there was a proper relation between state and civil society, and when the state trembled a sturdy structure of civil society was at once revealed.’ When in 1917 the Russian autocracy not only trembled but tumbled to the ground, there was no ‘powerful system of fortresses and earthworks,’ in Gramsci’s phrase, to prevent the Bolsheviks from erecting another absolutist regime in its place.”

civic society in russia first came to life under catherine the great (1729-1796), who did go some way to promote enlightenment ideals in the empire; perhaps more so when it came to the arts rather than politics, but still…it was a start, albeit one restricted in extent. from engelstein again [pg. 26 – my emphasis]:

“Eighteenth-century Russia had a lively public life. Private presses, a market in print, debating societies, literary salons, private theaters, public lectures, Masonic lodges — all linked inhabitants of the capitals and provincial centers in something of an empirewide conversation. Yet this world was limited in scope, audience, and resources and was fatally dependent on the autocrat’s good will. Catherine, when it pleased her, cracked down on independent publishers.”

this public life did continue to grow, however, although in fits and starts. nicholas i (1796-1855) was not too thrilled by it all, and alexander i (1777-1825) actually banned the freemasons, but by the nineteenth century, alexander ii (1818-1881) was, for a tsar, positively a radical when it came to permitting and promoting civic society as was evident in his great reforms. by the late nineteenth century then [pg. 16]:

“…an increasingly active public sphere of debate that included advocacy and representation was no longer in doubt in tsarist Russia. Thus well before the Revolution of 1905, the groundwork was laid for the participation of private associations in the public arena.”

the practice of joining voluntary organizations came later to the russian lower classes. consumer cooperatives began to appear in russia and the empire in the 1860s, but these first cooperatives were organized and run by the upper classes. peasants and workers would’ve been customers only. cooperatives among middle class professionals in towns and cities appear in the early-1890s. the idea spread to villages in 1900 via proselytizing intellectuals (also worth noting), and after 1905, the cooperative movement exploded right across the country. from The Co-operative Movement in Russia: Its History, Signficance, and Character (1917) by j.b. bubnoff — delightfully published in manchester by the co-operative printing society limited (so the work could be a bit biased) [pg. 49]:

“In 1891 consumers’ societies were formed in towns among the lower-grade officials, various classes of employees, teachers, members of liberal professions, and other sections of the population. These societies were of two types. One open only to members of a particular class of officials or to employees of a particular firm or institution; the other was open to all. These latter societies were already marked by the spirit of independence.

“Throughout this period the number of consumers’ societies was not large, and their output was small…. In 1900 the position was the same. Beginning from 1900, the Co-operative Movement spread in the villages…. [T]he first consumers’ societies in the villages were initiated by the intellectuals and by the authorities and were not the outcome of free enterprise on the part of the peasants themselves. At the end of the last century, and particularly at the beginning of the present one, an agrarian movement spread among the peasantry and ended in the revolution of 1905.”

by 1917, provided bubnoff wasn’t exaggerating, there were ca. 20,000 consumer cooperatives in russia (bubnoff notes that the other organizations listed in the table below — credit and loan savings associations, agricultural societies, and the artels — were all either government run or arranged by the large landowners, so they weren’t really voluntary associations in the sense of being organized by the members.):

Russia - The co-operative movement in Russia - table

again, though, this is late for finally getting around to launching civic institutions in your country. nineteen hundred and seventeen (1917) is very, very late compared to what happened in northwestern europe. even compared to what happened in northern italy. as valerie bunce says in “The Historical Origins of the East-West Divide: Civil Society, Politcal Society, and Democracy in Europe” [pg. 222]:

“By the end of the nineteenth century, then, it was evident that there were two Europes, long separated by their histories and, thus, by their politics, economics, social structure, and culture.”

not to mention their evolutionary histories.

so how did northwestern “core” europe (including northern italy) differ from russia historically as far as participation in civic institutions goes? the short answer is: civicness in “core” europe began centuries before it did in russia or the rest of eastern europe, at least 500-600, if not 800-900, years earlier.

here is putnam on the formation and functioning of communes in northern italy beginning in the 1000s [pg. 124-126]:

“[I]n the towns of northern and central Italy…an unprecedented form of self-government was emerging….

“Like the autocratic regime of Frederick II, the new republican regime was a response to the violence and anarchy endemic in medieval Europe, for savage vendettas among aristocratic clans had laid waste to the towns and countryside in the North as in the South. The solution invented in the North, however, was quite different, relying less on vertical hierarchy and more on horizontal collaboration. The communes sprang originally from voluntary associations, formed when groups of neighbors swore personal oaths to render one another mutual assistance, to provide for common defense and economic cooperation…. By the twelfth century communes had been established in Florence, Venice, Bologna, Genoa, Milan, and virtually all the other major towns of northern and central Italy, rooted historically in these primordial social contracts.

“The emerging communes were not democratic in our modern sense, for only a minority of the population were full members…. However, the extent of popular participation in government affairs was extraordinary by any standard: Daniel Waley describes the communes as ‘the paradise of the committee-man’ and reports that Siena, a town with roughly 5000 adult males, had 860 part-time city posts, while in larger towns the city council might have several thousand members, many of them active participants in the deliberations….

“As communal life progressed, guilds were formed by craftsmen and tradesmen to provide self-help and mutual assistance, for social as well as for strictly occupational purposes. ‘The oldest guild-statute is that of Verona, dating from 1303, but evidently copied from some much older statute. “Fraternal assistance in necessity of whatever kind,” “hospitality towards strangers, when passing through the town”…and “obligation of offering comfort in the case of debility” are among the obligations of the members.’ ‘Violation of statutes was met by boycott and social ostracism….’

“Beyond the guilds, local organizations, such as *vicinanze* (neighborhood associations), the *populus* (parish organizations that administered the goods of the local church and elected its priest), confraternities (religious societies for mutual assistance), politico-religious parties bound together by solemn oath-takings, and *consorterie* (‘tower societies’) formed to provide mutual security, were dominant in local affairs.”

in general, nothing like this existed in medieval russia (or eastern europe) — not on this scale anyway — the novgorod republic, which lasted for three centuries and came to an end in 1478, probably being the most notable exception. eastern european society was still very much founded upon the extended family for much of the period (although, again, in certain times and locales that was not the case — russia’s a big place). only a handful of merchants’ guilds were given permission to exist in russia between the fourteenth and eighteenth centuries, and the powers that be (including the orthodox church) regularly suppressed craftsmen’s guilds [pg. 13]. by contrast, northern italy was full of civic-mindedness already by the high middle ages.

meanwhile, in england (and other parts of northwestern europe) [pgs. 3-4]:

“As a form of voluntary association, bound by oath and by a (usually modest) material subscription, the fraternity or guild was widespread in late-medieval England and continental Europe. Both the ubiquity and the frequency of the form have been underlined by recent historical case-studies. While the particular purpose and activities of a fraternity might be infinitely various, the organization may be characterized in general as combining pious with social, economic, and political purposes. Its declared aims invariably included important religious functions, expressed in the invocation of a saintly patron and an annual mass with prayers for deceased members. With equal certainty, the annual feast day would bring the members together for a drink or a meal to celebrate their community. The overwhelming majority of English guilds admitted women alongside men: a feature generally characteristic of guilds of medieval northern Europe, although not so prevalent in the Mediterranean world. Sometimes described in modern English accounts as ‘parish fraternities’, these clubs indeed were often founded by groups of parishioners and regularly made use of an altar in a parish church as a devotional focus; yet they as often drew their memberships from a wider field than that of the parish, whose bounds they readily transcended…. An individual might join more than one guild, thereby extending still futher the range of his or her contacts. A significant minority of fraternities crystallized around a particular trade…. The overwhelming majority of guilds, however, were not tied by such association to a single craft, but brought together representatives of various trades and professions.”

extraordinarily, one type of fraternity — of non-kin remember (the whole point of voluntary associations is that they’re made up of non-kin) — appeared in england as early as the late-800s. from a previous post, the importance of the kindred in anglo-saxon society:

“the *gegildan* appears in some of the anglo-saxon laws in the late-800s as an alternative group of people to whom wergeld might be paid if the wronged individual had no kin. by the 900s, though, in southern england, the gegildan might be the only group that received wergeld, bypassing kin altogether. from Wage Labor and Guilds in Medieval Europe [pgs. 39-42]:

“‘The laws of King Alfred of Wessex, dated to 892-893 or a few years earlier, are more informative about the *gegildan*. Again, the context is murder and the wergild — the compensation required for the crime. By Alfred’s time, if not during Ine’s, the *gegildan* is clearly a group of associates who were not related by blood. The clearest example of this is in chapter 31 of the laws: ‘If a man in this position is slain — if he has no relatives (maternal or paternal) — half the wergild shall be paid to the king, and half to the *gegildan*.’ No information exists on the purpose of the *gegildan* other than its role as a substitute for kinship ties for those without any relatives. These associates, who presumably were bound together by an oath for mutual protection, if only to identify who was responsible, would benefit anyone, whether the person had relatives or not…. Although the evidence from the laws of Ine may be read either way, the *gegildan* seems to be an old social institution. As seen more clearly in the tenth and eleventh centuries, it acquired additional functions — a policing role and a religious character.

“‘The nobles, clergy, and commoners of London agreed upon a series of regulations for the city, with the encouragement and approval of King Athelstan, who caused the rules to be set down some time in the late 920s or 930s. The primary purpose of these ordinances was to maintain peace and security in the city, and all those supporting these goals had solemnly pledged themselves to this *gegildan*. This type of inclusive guild, sometimes referred to as a peace guild, was an attempt to create one more additional level of social responsibility to support the king and his officials in keeping the peaces. This social group of every responsible person in London is a broad one, and the law does not use the term *gegildan* to describe the association in general….

“‘The idea of a guild to keep the peace was not limited to London, and a document from the late tenth century contains the rules and duties of the thegn‘s guild in Cambridge. This guild appears to have been a private association, and no king or noble is mentioned as assenting to or encouraging this group. Most of the rules concern the principle purposes of this guild — the security of the members, which receives the most attention, and the spiritual benefits of membership itself. The guild performed the tasks of the old *gegildan*: the members were obliged to defend one another, collect the wergild, and take up vengeance against anyone refusing to pay compensation. The members also swore an oath of loyalty to each other, promising to bring the body of a deceased member to a chosen burial site and supply half the food for the funeral feast. For the first time, another category of help was made explicit — the guild bound itself to common almsgiving for departed members — and the oath of loyalty the members swore included both religious and secular affairs. Although in many respects this guild resembles a confraternity along the lines Hincmar established for the archdiocese of Rheims, the older purpose of the group — mutual protection with its necessary threat of vengeance — makes the Anglo-Saxon guild something more than a prayer meeting. To include almsgiving to members in distress would be a small step, given the scope of activities this guild established. There is no sign that the thegns cooperated in any economic endeavors, but older rules of rural society had already determined methods of sharing responsibility in the villages, and the thegns cooperated on everything that was important in their lives. The thegns of Cambridge had a guild that resembles in some important ways the communal oath, that will be discussed below, of some Italian cities in the next century.'”

the gegildan of early medieval england, then — a voluntary association, a fraternity — appeared on the scene something like two hundred years before the communes of northern italy arose, three hundred plus years before the novgorod republic was formed, and nearly nine hundred years before the russians gave civiness another shot (after novgorod). i’m not aware of any earlier such associations in western medieval europe, although they may have existed. it appears, too, that the gegildan appeared in situ in england, a newly developed social structure to take over some of the earlier functions of the rapidly disappearing kindred (including feuding and protection), although maybe the concept was imported from the carolingians — the heart of the preceding frankish kingdoms, austrasia, was where manorialism had begun, which was then imported across the channel, so perhaps the gegildan concept was as well.

whatever the case, it’s in the core of “core” europe, once again, that we find the earliest evidence for behavioral patterns that are now the hallmarks of western civilization: late marriage and nuclear families, lowest levels of cousin marriage for the longest period of time, low levels of violence, high levels of civic-mindedness (see above), universalism, unparalleled accomplishment — they all appear earliest (in medieval europe), and are still the strongest, in this central area (very roughly the area indicated by the green oval on this map).

so, now we come to it: why? why was it “evident” by the end of the nineteenth century that there were two europes, and what do all these long-standing historical differences have to do with it?
_____

the ultimate cause must lie in our biologies. humans are biological creatures, so there’s no way around it. we know that all behavioral traits are heritable, so we have to look to differences in the populations’ genetics and evolutionary histories.

as i wrote recently: evolution in humans is ongoing, recent, can be pretty rapid (within some constraints), and has been/is localized (as well as global). in fact, human evolution has sped up since the agricultural revolution since the number of individuals, and therefore mutations, on which natural selection might work skyrocketed in post-agricultural societies. remember, too, that “every society selects for something,” and that we’re talking about frequencies of genes in populations and that those frequencies can fluctuate up and down over time.

so there is NO reason NOT to suppose that the differences in behavioral traits that we see between european sub-populations today — including those between western and eastern europe — aren’t genetic and the result of differing evolutionary histories or pathways.

even rapid evolution takes time, though. we’re not talking one or two generations, but more like thirty or forty — fifty’s even better. point is, evolutionary changes don’t only occur on the scale of eons. they can also happen over the course of centuries (again, multiples of centuries, not just one or two). the circa eleven to twelve hundred years since the major restructuring of society that occurred in “core” europe in the early medieval period — i.e. the beginnings of manorialism, the start of consistent and sustained outbreeding (i.e. the avoidance of close cousin marriage), and the appearance of voluntary associations — is ample time for northwestern europeans to have gone down a unique evolutionary pathway and to acquire behavioral traits quite different from those of other europeans — including eastern europeans — who did not go down the same pathway (but who would’ve gone down their own evolutionary pathways, btw).

what i think happened was that the newly created socioeconomic structures and cultural (in this case largely religious) practices of the early medieval period in northwest “core” europe introduced a whole new set of selective pressures on northwest europeans compared to those which had existed previously. rather than a suite of traits connected to familial or nepostic altruism (or clannishness) being selected for, the new society selected for traits more connected to reciprocal altruism.

before the early medieval period, northwest europeans — looking away from the urbanized gallo-romans who may have been something of a special case (more on them another day) — had been kin-based populations of agri-pastoralists whose societies were characterized by inter-clan feuding, honor/shame (vs. integrity/guilt), and particularism (vs. universalism). i think these traits were under constant selection in those populations because: reproductive success in those societies was dependent upon one’s connection to, and one’s standing within, the extended kin-group, so, thanks to being tied to kin rather than non-kin, nepotistic altruism genes would’ve been favored over reciprocal altruism ones; the extended kin-group was the element within which most individuals would’ve interacted with others, those others being related individuals who would’ve been likely to share the same nepotistic altruism genes (alleles) [see here for more]; and cousin marriage was rife, which again would’ve further fuelled the selection for these genes, since members of the same kin-group would’ve had an even greater likelihood of sharing the same versions of their nepotistic altruism genes.

pretty much the opposite happened during the early and high middle ages in “core” europe. manorialism pushed for nuclear families rather than extended family groupings, and so people began to interact more with non-kin rather than kin, enabling the selection for more traits related to reciprocal altruism. the avoidance of close cousin marriage meant that family members would’ve shared fewer altruism genes in common, so any selection for nepotistic altruism would’ve slowed down. and once voluntary associations of non-kin appeared, the selection for reciprocal altruism really would’ve (or, at least, could’ve) taken off. reproductive success was no longer dependent upon connections to the extended family group, but, rather, unrelated individuals living with the community.

the manor system developed in the 500s in “core” europe (austrasia), but did not arrive in russia (and much of eastern europe) until the late medieval/early modern period. (it never got to the balkans.) the extended family was most likely gone on the manors in the west by the 800s (see mitterauer), although it is conceivable that the nuclear families found on the manors in the earliest days were residential nuclear familes rather than the fully atomized ones that we see in the west today. certainly by the 1500s, there are no longer any traces of the extended family among “core” europeans (although there are still some pockets). the avoidance of cousin marriage was underway in earnest by the 800s (possibly earlier, but definitely by the 800s). it was still on shaky ground as late as the 1400s in russia. and, as we’ve seen, voluntary associations appeared very early in “core” western europe, but only very recently in russia (and, presumably, other areas of eastern europe).
_____

most of you will recognize this as the hajnal line story (yet again!) with a few new nuances thrown in. manorialism, outbreeding, and voluntary associations all began in “core” europe — again very roughly the area outlined by the green oval on the map below (the other lines indicate, again roughly the extent of the hajnal line) — and they spread outwards from there over time, eventually reaching russia and other parts of eastern europe, but not until very late. (and the manor system in russia, once it was adopted there, was of a very different form than what had existed in western europe.)

hajnal line - core europe

inside the hajnal line, which (imo) reflects the extent of the strongest selection for behavioral traits related to reciprocal altruism over nepotistic altruism, the populations have stronger democratic traditions, are more civic-minded, are less corrupt, and score higher on individualism (vs. collectivism) on hofstede’s idv dimension than the populations outside the hajnal line. (please, see my big summary post on the hajnal line for more details.) all of these behavioral patterns “fit” better with the idea that these populations are characterized by innate reciprocal altruism tendencies rather than more nepotistic altruism ones. the populations outside the hajnal line seem to be more oppositely inclined.

there is no doubt that soviet communism wreaked havoc on eastern european populations. some untold millions died in the gulags, families and towns and villages were ripped apart, political repression was beyond belief. but smart money says that, along with civicness, many of the “non-western” features of contemporary eastern europe — high corruption rates, etc. — have deeper roots, and are not the consequences of communism, but rather of recent evolution by natural selection.

in Experimenting with Social Norms ensminger and henrich compile several very interesting studies on prosocial “fairness” norms conducted on various populations of different types — ranging from hunter-gatherers to urban factory workers — from around the world. three different economic experiments were conducted on the various populations (although it’s not clear to me if all three were run on each group — i haven’t read through all of each of the studies chapters yet): the ultimatum game, the third-party punishment or altruistic punishment game, and the dictator game.

the authors conclude that [pgs. 89-90]:

“1. Fairness and punishment show both reliable patterns and substantial variability across diverse populations.
2. Fairness increases with a population’s degree of market integration.
3. Fairness increases with an individual’s participation in a world religion.
4. Willingness to engage in punishment increases with community size.”

they ultimately conclude “that social norms evolved over thousands of years to allow strangers in more complex and large settlements to coexist, trade and prosper” — but they just mean that the norms and the cultures evolved, not the peoples.

possible biological/evolutionary reasons for the findings are given some consideration, but only across one and a half pages, and the authors end with the following [pg. 139]:

“Genetic differences between populations or groups would most likely account for the behavioral patterns we observe if they arose in response to stable differences in the culturally evolved social norms and institutions (formal and informal) found in different societies. Norms and institutions, in creating stable regularities in the local social environment, can theoretically produce conditions for natural selection to act on genes that make individuals better adapted to those particular norms and institutions (Henrich and Boyd 2001; Laland et al. 2010; McElreath, Boyd, and Richerson 2003; Richerson et al. 2010). This is an intriguing and provocative possibility, but there is no evidence at this point supporting a suspicion that such a culture-gene coevolutionary process has occurred.”

…and it’s too scary to think about anyway, so we won’t give it any more ink here. (>.<)

in 2010, re. pretty much the same data sets/findings, they had this to say [my emphasis]:

“These findings indicate that people living in small communities lacking market integration or world religions — absences that likely characterized all societies until the Holocene — display relatively little concern with fairness or punishing unfairness in transactions involving strangers or anonymous others. This result challenges the hypothesis that successful social interaction in large-scale societies — and the corresponding experimental findings — arise directly from an evolved psychology that mistakenly applies kin and reciprocity-based heuristics to strangers in vast populations (4,5), without any of the ‘psychological workarounds’ (42) that are created by norms and institutions. Moreover, it is not clear how this hypothesis can explain why we find so much variation among populations in our experimental measures and why this variation is so strongly related to MI, WR, and CS. The mere fact that the largest and most anonymous communities engage in substantially greater punishment relative to the smallest-scale societies, who punish very little, challenges this interpretation.”

this is old school evolutionary psychology at its worst — that human nature and the human psyche (and there’s only one sort in this viewpoint) stopped evolving at the end of the last ice age when a majority of us quit being hunter-gatherers.

well, i’ve got news for them: evolution in humans is ongoing, recent, can be pretty rapid (within some constraints), and has been/is localized (as well as global). in fact, human evolution has sped up since the agricultural revolution since the number of individuals, and therefore mutations, on which natural selection might work skyrocketed in post-agricultural societies.

remember, too, that all human behavioral traits are heritable (and more down to biology than many like to think), “every society selects for something,” and that we’re talking about frequencies of genes in populations and that those frequencies can fluctuate up and down over time.

given all of the above, there are NO good reasons for dismissing genetic or evolutionary explanations for variations in social norms between populations (and individuals for that matter). since we are biological creatures, biological explanations should be ruled out (properly!) first before moving on to other sorts of explanations.

again ensminger and henrich said:

“This result challenges the hypothesis that successful social interaction in large-scale societies — and the corresponding experimental findings — arise directly from an evolved psychology that mistakenly applies kin and reciprocity-based heuristics to strangers in vast populations, without any of the ‘psychological workarounds’ that are created by norms and institutions.”

no, of course not. a more likely scenario is that the behavioral traits realted to social norms in large-scale societies — post-agricultural societies (and post-post-agricultural societies) — evolved with some rapidity away from what had existed before in smaller societies thanks to: 1) the larger population size itself (generating a greater number of mutations), and 2) the larger societies and the structures that developed exerting new selective pressures on those populations in sort-of giant feedback loops — society selects for genes for new behavioral traits which in turn produces new societal forms, and so on.

more from the authors:

“Moreover, it is not clear how this hypothesis can explain why we find so much variation among populations in our experimental measures….”

well, that’s easily explained if you remember that human evolution is ongoing, recent, pretty rapid, and can be local.

to take just one example from their findings, if we look at their results from the dictator game…

mean dictator game offers

…it was primarily members of the hunter-gatherer or horticulturalist groups who gave low offers in the game, african agriculturalists (or pastoralists) middling offers, and the residents of hamilton, missouri, the highest. (annoyingly, a couple of the populations — accra and isanga — are groups of mixed ethnicities, so it’d be difficult for anybody to tease apart what’s going on.)

well, hunter-gatherers and horticulturalists — like the hadza, the tsimane’, the au, and the sursurunga — have largely missed out on the agricultural revolution and its evolutionary effects. the middling offers from the mostly african (mostly bantu) agriculturalists are not a surprise either since agriculture and the development of large-scale societies got going comparatively late in sub-saharan africa. and that the hamiltonians offered up the most money — and have the highest market integration — probably owes a lot to the fact that that population is a part of the u.s. midlands and are descended from a group that experienced the agricultural revolution back in the neolithic, and furthermore went through the selection pressures created by medieval manorialism and long-term outbreeding (and who knows what else?).

those are just a few ideas for starters. i’m sure it’s much more complicated than that. for instance, why are the tsimane’ forager-horticulturalists so stingy while the au from papua new guinea, who are also forager-horticulturalists, quite generous? i dunno, but one possibility i suggest checking out is the difference in the family structures of the two groups (prolly will be difficult to do this very far back in time): the interconnectedness of au families, which stretch between villages, is quite complex, while tsimane’ families are not so much (afaik). among many other possibilities and scenarios, we should be looking for the selection pressures created by family types and the flow of genes (especially for behavioral traits like altruism) through different family types.

one final thing – ensminger and henrich et al. from 2010:

“Methodologically, our findings suggest caution in interpreting behavioral experiments from industrialized populations as providing direct insights into human nature.”

well, quite. but it works in the other direction, too: we should also be cautious in interpreting behavioral experiments from non-industrialized populations as providing direct insights into human nature(s).

jayman’s got a cool new post up on clannishness and western inventiveness! here are a few thoughts from me…

jayman said re. the abstract thinking type of westerners vs. the holistic thinking type of easterners (a la nisbett) [my emphasis]:

“[A]nother key difference between Western vs. Eastern (i.e., WEIRDO vs. clannish) thought: the former see things (and themselves) as atomized individuals, while the latter view objects in the world as part of an interconnected whole. This is a defining aspect on the clannishness dimension: low-clannishness peoples (WEIRDOs) see themselves as atomized individuals, who form associations voluntarily and not necessarily based on kinship. High-clannishness peoples see themselves as inherently part of the group (e.g., family, clan, tribe, village/town, etc.)….

“How did this penchant for abstraction come about among NW Europeans? I suspect that part of it has to do with the rise of high-trust and social atomization (i.e., individualism) in NW European societies. As clannishness disappeared, and as people were no longer bound to their families or clans (and indeed, we were free to interact with non-relative in cooperative ventures), people became more free to engage in intellectually stimulating thought. Mental space previously devoted understand one’s place in society and keep ahead of schemers now could be used on more abstract pursuits.

while it’s an interesting idea, i don’t think that freed up mental capacity once dedicated to clannish traits was co-opted in the brains of westerners (nw europeans) in their post-clannishness state and then devoted greater abstract thought. maybe. but i suspect the connection is (somehow) much more direct: i think (theorize, speculate, etc.) that in simply becoming more independent individuals — i.e. less genetically like others around them thanks to outbreeding — that the mindset simply shifted. atomized individuals, atomized (and, therefore, abstract) thinking. please don’t get your panties all in a bunch. yes, this is complete and wild speculation on my part. i can’t even guess what the mechanism might have been, so don’t sue me if i’m wrong. (nw europeans, btw, began to think of themselves as individuals in the middle of the eleventh century a.d.)

another much more informed guess: that nw europeans’ exceptional ability for inventiveness especially in science (which cannot be divorced from their high average iqs — as jayman pointed out, africans are pretty inventive, but without enough iq points, no one there’s going to the moon) has a LOT to do with the selection pressures that happened thanks to the manor system which was found in nw europe during the middle ages, specifically bipartite manorialism.

to back up for a sec: inventiveness/creativity/scientific reasoning in east asians, or the relative lack of it. jayman suggests that their tendency for holistic — and, therefore, not abstract — thinking hobbles east asians when it comes to inventiveness, etc. that, i think, makes a lot of sense. i do think, though, that the cochran-harpending idea of conformity in east asia (“nails hammered down”/low levels of adhd) also makes a lot of sense. the two ideas go well together, imho. wrt the “nails hammered down” hypothesis, my bet is that that selection process goes waaaay back. complex chinese civilization (that centered around the yellow river valley) is three or four thousands of years old. i think they’ve been hammering down the contrarians/independent thinkers there for a very long time. greg cochran has mentioned that the high-altitude adaptation of tibetans works better than those of other groups adapted to living in the clouds because the tibetan adaptations have been under selection for longer (even some acquired from the denisovans and/or other archaic humans?). i suspect that this is why conformism/lack of independent thinking is so strong in east asia: it’s been under selection there for a very long time. northwest europe’s civilization is obviously much, much younger.

now, to return to northwest “core” europeans: i strongly suspect their inventiveness/abstract thinking style/scientific thinking (and other behavioral traits, for that matter) were selected for thanks to the the following medieval trifecta:

– outbreeding (i.e. the abandonment of close cousin marriage) which meant that the selection for nepostic altruism was curbed since family members would no longer share so many “genes for altruism” in common (see: renaissances), PLUS individuals became “atomized” (therefore more abstract thinking arose, etc.);
– change in family types from extended to nuclear, which again would limit the selection for nepotistic altruism since individuals would interact more with non-kin than family;
bipartite manorialism, which began in frankish territories in northeastern france/belgium and spread across nw and central europe in areas that are pretty much coterminous (prolly not coincidentally) with the hajnal line.

oh. and the ostsiedlung.

bipartite manorialism, in which tenant farmers would work for (later pay rent to) the head of a manor but also farm for themselves, operated as a sort-of franchise system in which the tenants on their individual farms had to make it or break it independently (i.e. without support from an extended family/clan, the dumber members of which would no longer be a drag on our independent farmers). there was, no doubt, cooperation between the tenant farmers which, once the outbreeding reduced the selection for nepotistic altruism, could’ve resulted in the selection for a more general, reciprocal altruism. but bipartite manorialism, i think, would’ve also selected for other traits like a propensity to be hard working, delayed gratification, and inventiveness: those individuals who came up with new ideas for improving their farming (or related) techniques could’ve bettered their place on the manor and been more successful reproductively.

chonologically, bipartite manorialism came first, arising out of the abandoned latifundia system in what had been roman gaul perhaps as early as the 500s. there also appears to have been pressure from very early on on these manors for nuclear families, so the reduction in family size may very well have come next. finally, the avoidance of cousin marriage came into full swing in the frankish territories in the 800s.

the final stage — at least as far as the medieval period goes — in the selection for “core” europeans was the ostsiedling: this was The Big Self-Sorting to the east of individuals who were already well underway to being outbred/manorialized in western germanic regions — in other words, they were well underway to being westernized as we know it. i don’t think it can be a coincidence that the heart of human accomplishment in western europe (which is also pretty much the heart of human accomplishment) is found in the manorialized regions of europe and very much where the ostsiedlung happened (see also here). my bet is that it was very much hard-working, innovative (especially, at the time, in agricultural/engineering techniques), high-achievers who went forth into the east during the medieval period. and they prospered and multiplied once they were there.

so that’s the picture as i see it so far. i reserve the right to change my mind/be utterly and completely wrong. (~_^)
_____

oh. wrt to thinking like a westerner (abstract/atomized) vs. thinking like an easterner (holistic/group), i still suspect that peripheral europeans (like me!) might think more like easterners (i.e. holistically) than northwest “core” europeans. dunno for sure, and i didn’t have enough data to confirm or refute this little idea, but i’m still hanging on to it for now. really wish an actual scientist would check it out.

jayman also said [his emphases]:

“The reality is that evolution proceeds much quicker than you think. Just as HBD’ers generally understand that human evolution didn’t stop 50,000 years ago, it also did not stop 10,000 years ago, or even 1,000 years ago, or even 500 or 200 years ago. Evolution continues right up to the present day. The reason I bring this up is because I keep hearing about how X group was doing this 2,000 years ago or about how Y group was doing this 1,000 years ago, so how could they be so different now? The reason is that they have changed since that time.

hear, hear! and…duh! human evolution is recent, both global and local, ongoing, and can be pretty rapid. not in one generation, obviously, but twenty or forty is plenty of time. also, gene frequencies in populations move upwards or downwards over time — they do not (have to) remain stagnant. i quoted stephen stearns recently (here):

“Well I think what is very probably going on is that selection is moving a population up and down all the time. It goes off in a certain direction for a while, and then it goes back in the other direction. It’s only if you get a significant change in the environment that it will then continuously go in a new direction.”

and average differences in gene frequencies in populations is all you need for average differences in behavioral traits, etc. for example, i think the ancient greeks might’ve moved from a shame to a part-guilt and back to a shame culture again thanks (at least in part) to changes in mating patterns over the course of several hundreds of years. evolution does not have to be unidirectional.

“Ancient Greeks did a lot of abstract thinking, and produced the greatest cultural/scientific peak until the Renaissance (according to the same Charles Murray’s figures). During the Middle Ages, in pure scientific terms, the Islamic world was most advanced. The Renaissance began in northern Italy. Only in the 17th century did the bulk of scientific discoveries move to NW Europe.”

as i mentioned above, it looks like the ancient greeks (the athenians) went from inbred to outbred and back to inbred again. mind you, i only have some pretty slim historic/literary evidence for that, so you should take my claim with a large grain of salt, but i’ll keep working on the Greek Question. the romans, who were also pretty sharp, at least when it came to engineering, were very clearly outbred (they bequeathed their outbreeding practices to us). the renaissance did begin in northern italy, and that doesn’t come as a big surprise to me ’cause northern italy was the most heavily manorialized part of italy (i’ll tell you more about this in my long overdue series on manorialism). northern italians were also prboably quite outbred during the medieval period, although further research is required on that front, too. the scientific revolution, however — especially the development of the scientific method — was very much a north european baby, though. from what i understand of science in the medieval islamic world, most of that was down to the persians. can’t tell you anything about medieval persian society, unfortunately, ’cause i don’t know anything about it.
