not totally slacking off!

i have been researching crime and punishment in medieval europe so you don’t have to! (^_^)

remember my last post sneak preview: violence, punishment, outbreeding, and swashbuckling pirates in medieval england? — in which i quoted manuel eisner [pdf]:

“‘Although the long-term expansion of the state and the decline of lethal violence appear to correlate nicely on the surface, a closer look reveals several inconsistencies. Muchembled (1996), for example, points out that the decline of homicide rates in early modern Europe does not appear to correspond with the rise of the absolutist state. Rather, he argues, the example of the Low Countries shows that homicide rates declined in polities where centralized power structures never emerged and the political system much more resembled a loose association of largely independent units. Neither does intensified policing nor the harsh regime of public corporal punishment, both probably the most immediate manifestations of state power in any premodern society, seem to aid understanding of the trajectories into lower levels of homicide rates.'”

well, i’ve now got that muchembled 1996 article — “Elias und die neuere historische Forschung in Frankreich” — and i’ll post about that as soon as i (*ahem*) quit slacking off (and find my german-english dictionary). (~_^)

slacking off

i know it seems as though your hbd chick has been slacking off this past week — which, given my low scores for conscientiousness, would not have been a bad guess on your part — but i have in fact been trying to become more intelligent via osmosis (the only way it’s going to happen at this point) by hanging out at the london conference on intelligence 2014. (^_^)

don’t know if my clever plan has worked or not, but i can at least point you to the summaries of a couple of the presentations that dr. thompson has posted on his blog. yes, he has promised to put them all up there!:

sneak preview: violence, punishment, outbreeding, and swashbuckling pirates in medieval england

preview screen

this is just a preview of a post that i’m working on — one on which i unfortunately have not made much headway, mostly because there’s an awful lot out there available to read on the topic (which is a good thing!). i promise, though, that — whenever it does materialize — that post will be a rip-roaring tale of medieval action and adventure! a thrilling and suspense-filled bodice ripper dealing with the themes of passion and madness! good versus evil! violence and punishment! swashbuckling pirates and….

no, wait. hang on a second. that’s not right.

no. as i mentioned in the last post, i’ve been reading up on violence (homicide) and the death penalty in medieval england to see if there exists any evidence to support the perfectly sensible theory that the removal of violent individuals — and, most importantly, their “genes for violence” — from the population in medieval europe (in this case england) resulted in the permanent decline in violence in europe as noted by historians of crime, like manuel eisner, and described by pinker in Better Angels.

the decline in homicides across europe that began in the middle ages is summarized in this chart from Better Angels (note the logarithmic scale):

pinker - fig. 3.3

the reader’s digest version of what i’ve found out about the death penalty in medieval england so far is:

– over the course anglo-saxon period (which isn’t actually covered by the above chart), 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. in fact, the nascent state (such as it was during this early period) was more concerned about applying the death penalty in cases of theft rather than murder or manslaughter. for most of this period, murder was still avenged by the deceased person’s kindred, either in the collection of wergild or via the good old blood feud. this did begin to change by the tenth and eleventh centuries as more laws that included the death penalty for killings were issued, but even in these later centuries the archaeological evidence suggests that few executions actually happened.

– more laws demanding the death penalty (or castration) for killings were issued and enforced during the anglo-norman and angevin periods, especially as the centralized state became stronger and began to exercise greater control throughout england. one funny thing, though — jury trials were more or less invented during this period (the jury was more of an investigative body, though, like a grand jury rather than twelve angry men passing judgement), and it turns out that the juries tended to be a bit reticent about applying the laws too harshly, so executions actually remained comparatively low during large parts of the norman period. i think you can see this in the trend line on pinker’s graph — homicides do decrease from about 1300 to 1500, but the decline is not super steep.

– the tudor 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. regional (county-wide) figures from the period show that, depending on time and place, anywhere from 27-50% of felons were executed. and, as you can see on pinker’s chart, the decline in homicides begins to decline sharply after around 1600.

that’s all i’ve got so far, but i’m pretty convinced that the idea that violence declined so much and with such rapidity in the medieval period in england (and the rest of europe?) is at least partly related to the fact that violent individuals were simply removed from the population — and it must’ve been done generally early enough in their careers to stop them reproducing — or slow down their reproductive rates enough that the population was pacified.

don’t think this is the whole story, though. the argument of the population being pacified thanks to the application of the death penalty by the state — by “leviathan” — doesn’t really seem to work fully or for all parts of europe. here is eisner on the differences between what happened in northern medieval europe versus medieval italy [pgs. 127-129 – pdf]:

“Strangely one-sided in respect to the role of the state as an internally pacifying institution, Elias almost exclusively emphasizes the state’s coercive potential exercised through the subordination of other power holders and bureaucratic control. Echoing the old Hobbesian theme, the decline in interpersonal violence should thus develop out of increased state control. Although the long-term expansion of the state and the decline of lethal violence appear to correlate nicely on the surface, a closer look reveals several inconsistencies. Muchembled (1996), for example, points out that the decline of homicide rates in early modern Europe does not appear to correspond with the rise of the absolutist state. Rather, he argues, the example of the Low Countries shows that homicide rates declined in polities where centralized power structures never emerged and the political system much more resembled a loose association of largely independent units. Neither does intensified policing nor the harsh regime of public corporal punishment, both probably the most immediate manifestations of state power in any premodern society, seem to aid understanding of the trajectories into lower levels of homicide rates. Police forces in medieval and early modern Italian cities were surprisingly large — Schwerhoff (1991, p. 61) cites per capita figures of between 1:145 and 1:800 — but they did not effectively suppress everyday violence. Furthermore, no historian seems to believe that the popularity of the scaffold and the garrote among sixteenth- and seventeenth-century European rulers decisively reduced crime.

“Rather, the Italian case exemplifies a more general problem. For whatever the deficiencies of early modern Italian states may have been, they were certainly not characterized by a lesser overall level of state bureaucracy and judicial control than, for example, states in England or Sweden during the same period (see, e.g., Brackett 1992). England was not centralized in bureaucratic terms, and the physical means of coercion, in terms of armed forces, were slight (Sharpe 1996, p. 67). The mere rise of more bureaucratic and centralized state structures thus hardly seems to account for the increasingly divergent development of homicide rates in northern and southern Europe. Examining Rome, Blastenbrei (1995, p. 284) argues that the divergence may, rather, be related to the evolution of different models of the relationship between the state and civil society. While northern European societies were increasingly characterized by a gradually increasing legitimacy for the state as an overarching institution, the South was marked by a deep rupture between the population and the state authorities. In respect to state control, Roth emphasizes a similar point when examining the massive drop in homicide rates in New England from 1630 to 1800: ‘The sudden decline in homicide did not correlate with improved economic circumstances, stronger courts, or better policing. It did, however, correlate with the rise of intense feelings of Protestant and racial solidarity among the colonists, as two wars and a revolution united the formerly divided colonists against New England’s native in habitants, against the French, and against their own Catholic Monarch, James II’ (2001, p. 55).

Both Roth and Blastenbrei emphasize, from different angles, a sociological dimension whose importance for understanding the longterm decline in serious violence has not yet been systematically explored, namely, mutual trust and the legitimacy of the state as foundations for the rise of civil society. Both are, of course, clearly to be distinguished from the coercive potential of the state — strong states in terms of coercion can be illegitimate, while seemingly weak states may enjoy high legitimacy. And on the level of macro-transhistorical comparison, the decline of homicide rates appears to correspond more with integration based on trust than with control based on coercion.

yeah. and y’all know what i have to say about all that. (^_^) but i won’t bore you with repeating myself just now — i’ll let you go enjoy the easter holidays. stay tuned for more on this in the near future!

random notes: 04/16/14

busy reading all about crime and punishment (i.e. the death penalty) in medieval england, so you don’t have to! (^_^) in the meantime, until i post about that, here are some random notes:

the law codes of ine king of wessex (688-726) are some of the earliest anglo-saxon law codes still surviving. they were issued ca. 694. ine took his christianity seriously and demanded that [pg. 27]:

“[A]ll children were to be baptised within 30 days of their birth, failing which their guardians had to pay a fine of 30 shillings. If a child died before baptism its guardian lost all he possessed….”

so there are some strong incentives for the populace to convert to christianity or remain christian once they’d done so.
_____

æthelstan, king of the anglo-saxons and then the first king of the north english (924-939), also passed a bunch of laws including [pg. 32]:

“[T]he first social legislation in England, providing for the relief of the poor. If a king’s reeve failed to provide, from the rents of the royal demesne, for the poor in the manner prescribed he had to find 30 shillings to be distributed among the poor under the bishop’s supervision.”

nice of him! (^_^)
_____

some examples of concerns about consanguinity issues in the late anglo-saxon period [pg. 226]:

“General concern about marriage and sexual relations within the kin is expressed throughout our period, for example, in the late ninth century in letters from Pope John VIII to Burgred, king of the Mercians, and to Æthelred, archbishop of Canterbury, and another from Fulk, archbishop of Reims, to King Alfred. In the 950s, according to the ‘Anglo-Saxon Chronicle’, ‘Archbishop Oda separated King Eadwig and Ælfgifu because they were too closely related’. They may have shared a great-great-grandfather, King Æthelwulf of Wessex….”

so there you go.
_____

and in anglo-norman england [pgs. 435-437]:

“As in the Anglo-Saxon period, a central issue was consanguinity. In the second half of the eleventh century and particularly under the influence of the reformer Peter Damian, the method of counting the prohibited degrees was established in its most extensive form. Instead of counting to see if there was a common ancestor within four generations, the counting was taken a further three generations back, to the seventh. This had the effect of extending the range of prohibited marriage partners to sixth cousins.[12] In England, the prohibition ‘to the seventh degree’ was decreed at ecclesiastical councils at London in 1074 x 1075, and at Westminster in 1102 and 1125: ‘between those related by blood or relatives by affinity [i.e. by marriage], up to the seventh generation, we prohibit marriages to be contracted. If indeed anyone shall have been thus joined together, let them be separated’. Reformers also emphasised other non-blood relationships, especially spiritual kinship. The potential for conflict with lay practice must have increased significantly, as it has been suggested that whilst the layity did not commonly contract marriages within four degrees, they did within five or six.[15]

“[12] It has been suggested that blood relationships alone might mean that the bride or groom had over 2,500 cousins of their own generation whom they were prohibited to marry; J.-L. Flandrin, Families in Former Times, trans. R. Southern (Cambridge, 1979), 24.

“[15] E.g. Green, Aristocracy, 348-9.”

2,500 cousins that you couldn’t marry. awkward that.
_____

interestingly (at least to me!), from late anglo-saxon england [pg. 242 – link added by me]:

“A further important tie was that of spiritual kinship, created particularly at baptism, but also at the catechumenate and confirmation. It seems that in England, unlike the Continent, there was only one sponsor, of the same sex as the person undergoing the ceremony. This is one reason for the relatively limited emphasis in England on the need for the group of godparents and their godchild to avoid sexual relations or marriage within the group.[114]

“[114] J.H. Lynch, Christianizing Kinship: Ritual Sponsorship in Anglo-Saxon England. 1998.”

huh! who knew?
_____

and, finally, just to remind everyone how barbaric the barbarians were [pg. 186]:

“The laws of Æthelstan mention drowning or throwing from a cliff for free women, stoning for male slaves, burning for female slaves:

“‘In the case of a male slave, sixty and twenty slaves shall go and stone him. And if any of them fails three times to hit him, he shall himself be scourged three times. When a slave guilty of theft has been put to death, each of those slaves shall give three pennies to his lord. In the case of a female slave who commits an act of theft anywhere except against her master or mistress, sixty and twenty female slaves shall go and bring three logs each and burn that one slave; and they shall pay as many pennies as males slaves would have to pay, or suffer scourging as has been stated above with references to male slaves.’

“However, the literary and archaeology evidence just cited suggests that hanging and beheading were the most common methods.”

Svante Paabo talk at NIH“According to Dr. Paabo, Ust-Ishim has longer Neandertal chunks than modern humans and this can be used to estimate that the admixture with Neandertals happened 331+/-99 generations before its time of 45,000y BP, or around 50-60,000y BP…. This pretty much proves that there were modern humans in Eurasia before the Upper Paleolithic revolution and disproves Richard Klein’s theory that modern humans together with UP technologies spread Out-of-Africa only after 50,000 years ago.” – from dienekes.

Europeans have three times more Neanderthal genes for lipid catabolism than Asians or Africans“Contemporary Europeans have as many as three times more Neanderthal variants in genes involved in lipid catabolism than Asians and Africans. Although Neanderthals are extinct, fragments of their genomes persist in modern humans. These shared regions are unevenly distributed across the genome and some regions are particularly enriched with Neanderthal variants.”

The really old Europe is mostly in Eastern Europe“‘These results confirm Sardinia as a refuge area where ancestry related to Early European Farmers has been best preserved, and also the greater persistence of WHG-related ancestry in present-day Eastern European populations. The latter finding suggests that West European Hunter-Gatherers (so-named because of the prevalence of Loschbour and La Braña) or populations related to them have contributed to the ancestry of present-day Eastern European groups.'” – @eurogenes blog.

More on Deafness“Seems to me that limited verbal stimulation is not a very plausible primary cause of low test scores and low academic achievement in blacks, because the degree of deprivation needed to cause a 1-standard deviation decline is extreme (deafness), and because there is an even greater depression of nonverbal scores, which, judging from the results in deaf children, should not be affected at all by limited verbal stimulation.” – from greg cochran.

Whole genome sequencing of six dog breeds from continuous altitudes reveals adaption to high-altitude hypoxia“To understand the genetic bases of adaption to high altitude in dogs, we performed whole-genome sequencing of 60 dogs including five breeds living at continuous altitudes along the Tibetan plateau from 800 to 5,100 m as well as one European breed…. Comparison of the breeds from different altitudes reveals strong signals of population differentiation at the locus of hypoxia-related genes including endothelial Per-Arnt-Sim (PAS) domain protein 1 (EPAS1) and beta hemoglobin cluster. Especially, four novel non-synonymous mutations specific to high-altitude dogs are identified at EPAS1, one of which occurred at a quite conserved site in the PAS domain. The association testing between EPAS1 genotypes and blood-related phenotypes on additional high-altitude dogs reveals that the homozygous mutation is associated with the decreased blood flow resistance, which may help to improve hemorheologic fitness. Interestingly, EPAS1 was also identified as a selective target in Tibetan highlanders, though no amino acid changes were found. Thus, our results not only indicate parallel evolution of humans and dogs in adaption to high-altitude hypoxia, but also provide a new opportunity to study the role of EPAS1 in the adaptive processes.” – h/t joe pickerell!

Facial Width-To-Height Ratio Relates to Alpha Status and Assertive Personality in Capuchin Monkeys“fWHR was positively associated with alpha status and with a dimensional rating of assertive personality in both males and females. Moreover, fWHR showed significant sexual dimorphism in adults but not juveniles, suggesting a developmental change may occur during puberty. In a sub-sample, sex differences were mediated by weight, suggesting fWHR dimorphism does not exceed what would be expected by differences in body weight. This is the first report of an association between face shape and behaviour in a non-human species.” – h/t stuart ritchie!

The relationship between Microcephalin, ASPM and intelligence: A reconsideration“Microcephalin is strongly associated with DNA repair, which indicates a special role for this allele in the intrinsic anti-viral immune response. Enhanced immune functioning may have advantaged both hunter–gatherer and agrarian societies coping with the heightened disease burden that resulted from population growth and exposure to zoonotic diseases, making it more likely that such growth and concomitant increases in intelligence could occur.” – from michael woodley et al. – see also The riddle of Microcephalin – from peter frost.

Caucasian Boys Show Highest Prevalence of Color Blindness Among Preschoolers“The first major study of color blindness in a multi-ethnic group of preschoolers has uncovered that Caucasian male children have the highest prevalence among four major ethnicities, with 1 in 20 testing color blind. Researchers also found that color blindness, or color vision deficiency, in boys is lowest in African-Americans, and confirmed that girls have a much lower prevalence of color blindness than boys.”

That’s demonstrably false,’ says the neuroscientist David Eagleman, author of Incognito: The Secret Lives of the Brain.

The truth is that of course men and women are equal (all human beings are equal), but this does not mean that they are, on average, the same. 2 + 3 = 10 – 5, but these expressions are not the same.
