father’s brother’s daughter (fbd) marriage and honor killings

i took this table from the recent pew survey of muslims

honor killings permissible - pew 2013

…and made a couple of maps (adapted from this map).

the first one is a map of the differences between what percentage of muslims in each country responded that honor killing is never justifiable when a man commits an offense versus a woman committing an offense. a plus number (+) means more enthusiasm for honor killing women — a negative (-), men. here it is (click on image for LARGER view):

map of expansion of caliphate - pew honor killings diffs

what i think we can see is that, the closer you get to the arab expansion epicenter (the arab peninsula), the greater the enthusiasm for honor killing women. so in jordan it’s +47, lebanon and egypt +10, iraq +11. but when you get out to the edges of the caliphate, the differences are not so great, or they are in fact reversed: morocco -1, turkey and afghanistan and tajikistan 0. even pakistan is only +3. when you get way out to uzbekistan and kyrgyzstan, then the numbers are reversed: -14 and -3.

(it should be noted that for some reason the question was worded differently in uzbekistan, afghanistan, and iraq. everyone else was asked specifically about premarital sex/adultery and family honor, while the uzbekis, afghanis, and iraqis were only asked about family honor. see questions 53 and 54 here [pdf].)

i think that perhaps this is a reflection of what korotayev noticed, i.e. that father’s brother’s daughter (fbd) marriage is found in those places of the world that were a part of the eighth century muslim caliphate, because those populations wanted to emulate the arabs, and the arabs practiced fbd marriage. the reason that the populations on the edges of the caliphate are less enthusiastic about honor killing women is that they were arabized less and/or later than (dare i say it) the “core arabs” and so probably have been practicing fbd marriage for a shorter amount of time. (in fact, korotayev and other russian anthropologists suggest that fbd marriage started in the levant and moved southwards into the arab peninsula, so some of the jordanians and lebanese may have started practicing fbd marriage before the arabs down in the peninsula.)

i think, too, that there is a connection between fbd marriage and honor killings, because fbd marriage leads to greater inbreeding, and greater amounts of inbreeding may very probably lead to greater frequencies of “genes for altruism” — and honor killings can be viewed as a sort-of upside-down-and-backwards form of altruism (at least they seem that way to us).

and/or the arabs simply introduced some crazy “genes for upside-down-and-backwards altruism” to these various populations, and less so on the fringes presumably because not so many arabs actually made it that far. edit: also interesting to note is that in fbd societies, all of the men in extended families/clans share the same y-chromosome. if there is a connection between violence and some gene(s) on the y-chromosome (i thought greg cochran said something about this, but i can’t find it now), maybe this is exacerbated by fbd marriage.

here is the other map — the percentage of muslims in each country responding that it is rarely, sometimes, or often justified to honor kill women:

again, the numbers taper off on the edges of the extent of the caliphate.

who wants sharia?

pew has just released the results of their latest survey of muslims around the world (in 39 different countries).

here’s a map showing the percentage of muslims in each country that would like sharia to be the law of their land (click on map for LARGER image – should take you to the pew site):

who wants sharia - pew 2013

the iraqs, afghanis, and pakistanis all seem pretty eager for sharia — they’re all in the 75-100% range. the moroccans, too. and the palestinian territories.

this is a large report from pew, so have a look at the whole thing yourself.

here’s something else that i found particularly interesting:

honor killings permissible - pew 2013

of the countries that think that honor killing is more justified when women commit an offense than when men do — russia, albania, azerbaijan, bangladesh, pakistan, jordan, iraq, egypt, lebanon, tunisia, and the palestinian territories — a majority of them (7 out of 11) have a preference for father’s brother’s daughter’s (fbd) marriage — pakistan, jordan, iraq, egypt, lebanon, tunisia, and the palestinian territories.

i don’t know what, if any, form of cousin marriage is preferred in azerbaijan or bangladesh. paternal cousin marriage, which would include fbd marriage, is avoided in places like chechnya and (at least among some peoples in) dagestan (russia in this survey?) and albania. the difference in the responses in albania was not very great (+1 point), but the difference in russia(?) was statistically significant at +7 points. it’s difficult to know who these “russian” muslims are (maybe the info is in an appendix somewhere — i’ll have to look), so i don’t know if they’re the chechens and/or some dagestanis and/or some other group(s) — and, so, i don’t know what their mating patterns are.

i’m surprised that afghanistan breaks even. i would’ve predicted that they would be like the other fbd marriage groups.

it’s interesting that some of the central asian “stans” — kyrgyzstan and uzbekistan — swing in the opposite direction. a greater number of people feel that honor killings are more justified against men who break the rules than women. i don’t know much of anything about these populations, but i did read a bit just the other day, and it seems that they have a preference for maternal cousin marriage. (note that i don’t have a good idea what the rates might be.)

consanguinity and islam and democracy

i said last week that the week would be devoted to the woodley & bell consanguinity and democracy paper … and then i got distracted. typical. so, now, back on track…

aside from looking for any straight up connection/s between consanguinity and democracy (see previous post), woodley & bell also looked at consanguinity and democracy and several other possible factors that might affect the success of democracy in the nations included in the study: economic freedom, inequality, exports of fossil fuels (the “resource curse”), pathogen load (i’ll come back to that one!), and islam.

using path analysis, they found that islam seems to have a direct impact on democracy in muslim nations and ALSO that islam has an indirect impact on democracy via consanguinity.

recall that woodley & bell used two different indices of democracy: data from the polity iv project and the eiu democracy index. so they worked up two path analyses (click on charts for LARGER view). percent muslim for each country came from pew:

both analyses indicate: “that Islam has both direct effects on democracy and effects that are mediated by consanguinity, although the direct path from percentage Muslim to democracy [in the first model] only approached the conventional cutoff for significance (p = .096).”

from the paper (pg. 12):

“The largest impacts on consanguinity in the path models were produced by pathogen load and the effect of the percentage of Muslims within a nation. In the first path model the latter variable did not have a significant direct path to democracy, which suggests that its effects on democracy are largely mediated by consanguinity. Both pathogen prevalence and the influence of Islam have been described in the literature as having an inhibitory effect on democracy (e.g., Fincher et al., 2008; Fish, 2002; Fukuyama, 2001; Huntington, 1984; Thornhill et al., 2009). Here we indicate that these variables, which had previously been posited to have independent effects on democracy, are actually mediated by consanguinity.”

so, if a nation is islamic, that will affect how democratic it is (or not!), but what seems to be more important is if the population practices cousin marriage. it’s islam+consanguinity that is the key here, not just islam.

i think it makes sense that the effects islam has on democracy are “mediated” by how much cousin marriage there is in a society. cousin marriage directly affects the genetic relatedness between the individual members of a population, making individuals more related to their family members than would happen in an outbred society, while making those same individuals less related to non-family members, again unlike in an outbred society. i think this pretty clearly leads to clannish or tribal behavioral patterns which, as woodley and bell point out, are not conducive to liberal democracy at all.

islam doesn’t demand cousin marriage, but it doesn’t prohibit it either. since muslims are supposed to emulate mohammed (who married a cousin – see below), it probably rather encourages it. and anyway — which came first, cousin marriage or islam? yup. cousin marriage. one of mohammed’s wives was a cousin of his (his fzd) — and ali (yes that ali), who was mohammed’s cousin, married mohammed’s daughter, ali’s first cousin once removed. cousin marriage was very much the norm amongst the arabs in mohammed’s day. and, unlike roman catholic church policy makers, neither mohammed nor any imam since him (at least none that count) seem to have come down against cousin marriage afaik.

furthermore, good ol’ father’s brother’s daughter (fbd) marriage, the form of cousin marriage that leads to the most inbreeding, and that is still the preferred form amongst many muslims, was probably already well established amongst the arabs in mohammed’s day. fbd marriage was probably introduced to the arabs by jewish tribes from the levant who migrated into the arab peninsula starting in the second century b.c. so not only is cousin marriage amongst the arabs old, it’s really old — and it’s fbd marriage to boot. the arabs went on to introduce fbd marriage to the peoples of north africa, the mashriq and south asia (like the pakistanis and the afghanis).

my guess is that it’s not just the amount of consanguinity in a nation that negatively affects the success of democracy in that country, but the length of time the people have been practicing cousin marriage AND how close that cousin marriage is. like i said in the previous post, i think the evolution of “genes for altruism” comes into play here, not just the immediate genetic relatedness between the individuals in these societies, although it’s important, too.

so, i would bet that democracy would fare the worst in the levant, where fbd marriage originated, and the arab peninsula, where fbd marriage has been present for so very long, and that distance from that core region would predict better odds of democracy working at all.

kinda looks that way, don’t it? (eui democracy index 2011 – click on map for LARGER view):

syria, saudi arabia, yeman and oman have the worst scores for democracy in the muslim world (in the world!). iran, turkemenistan and uzbekistan have similar scores and all three of those countries were “arabized” in the early- to mid- seventh century a.d. pakistan was not brought under the arab sphere of influence until later (the early eighth century) and conversion to islam and arabization (and, presumably, the adoption of fbd marriage) took some time. this, i think, might partially explain why, even though pakistan today has similar consanguinity rates to saudi arabia, it does better as far as having a democratic state goes — the pakistani populations haven’t been marrying their fbd for as long as arabs.

similarly, at the other end of the “arab” world, north africans are relatively better at democracy than the saudis since they, too, were arabized — and adopted fbd marriage — comparatively late. the far flung islamic nation, indonesia, manages democracy fairly ok since they’ve hardly adopted fbd marriage at all, although they’ve probably been marrying their mother’s brother’s daughters for a while like other east asian populations.

poor people don’t like terrorists

at least not in pakistan (at least not the ones in this survey). it’s the middle class you gotta watch out for (edit: like the ones in abbottabad maybe?):

“Pakistan’s Middle Class Extremists”

“The data revealed four findings that undermine common wisdom about support for militancy in Pakistan. First, survey participants were generally negatively inclined toward all four militant organizations….

“Second, Pakistanis living in violent parts of the country, in Khyber-Pakhtunkhwa in particular, strongly disliked these groups….

“Third, poor Pakistanis nationwide disliked the militant groups about two times more than middle class Pakistanis, who were mildly positive toward the groups….

“Finally, this dislike is strongest among poor urban residents….”

so, if you’re stuck living (or dying) with extremists and terrorists in your neighborhood, you’re prolly reeeally not gonna like them. makes sense.

fixing the “bare branches” problem

from new scientist on trying to fix the “bare branches” problem in china:

“How great is the gender imbalance in China?

“In 2005, there were 32 million more men than women under the age of 20 in China. Young men with no prospect of marriage become a disruptive force in society. And with no one to marry, they will have no children and no one to take care of them when they are too old to work.

“Is the imbalance an unintended consequence of China’s one-child policy?

“Gender-selective abortions exacerbate the problem of dwindling birth rates. In China, a son is not just a source of pride, but a financial necessity. A daughter leaves home to join her husband’s family after marriage, so her parents have no one to care for them in their old age….

“How do you stop sex-selective abortion?

“In rural areas it is easier to enforce the rules as most doctors are government employees. The local Family Planning Commission official may monitor pregnancies to ensure that mothers do not abort for reasons other than a medical issue. In cities the policy is harder to enforce, and a black market for sonogram services has emerged.”

and here’s a little more background from the nyt from a few years ago:

“Surplus males: The dangers of Asia’s preference for sons”

“The most populous nations in Asia, including China, India and Pakistan, have acted upon their deep cultural preference for sons by culling daughters from their populations through the use of ever more efficient sex selective technologies….

“The technology to select male offspring before birth began to spread in the late 1980s, and the birth sex ratios began to rise. In China, the official ratio is 117 boys born for every 100 girls, but the reality is probably 120 or more. In India, the official birth sex ratio is 111-114 boys per 100 girls, but spot checks show ratios of up to 156 boys per 100 girls in some locales. For comparison, normal birth sex ratios are 105-107 boys born per 100 girls.

The mortality rate for girls and young women is also much higher than normal in these countries, further exacerbating the deficit. For example, the U.S. Bureau of the Census estimates excess deaths among Chinese females in the first year of life alone to be close to half a million. In India, almost one million more girls than boys die in the first five years of life….”

sounds like infanticide to me. here’s some more:

“Using conservative estimates, in 2020 India will have about 28 million more young males (aged 15 to 34) than young females. In China, the figure will be closer to 30 million; in Pakistan it will probably be 3-5 million.

“In China there is a term for such young men: guang gun-er, or ‘bare branches’ on the family tree — males who will probably not raise families of their own because the girls who should have grown up to become their wives fell victim to female infanticide.

The ‘bare branch’ populations in China and India, comprising about 12 to 15 percent of their young adult males, will be overwhelmingly poor, uneducated, unskilled and possibly unemployed. Throughout the millennia in which son preference has been effected in China, India and Pakistan, the bare branches have been one of the most volatile elements in society, frequently causing great social instability through crime and violence, and when uniting in a common movement, an important threat to the government itself.

“In Chinese history, for example, the Nien Rebellion, the Black Flag Army, the Boxers, the Eight Trigrams Rebellion and even the famous Shaolin fighting monks were all essentially bare-branch collectives doing what they did best: using force to acquire the resources otherwise denied them.

“The Nien, for example, came from an impoverished province where the sex ratio was 129 to 100. They began as petty bandits and smugglers, but soon coalesced into larger criminal brotherhoods. At the height of the rebellion, their leaders could boast of an army of more than 100,000 bare branches, which controlled an area populated by almost six million persons….

China is already experiencing a tremendous increase in crime, and 50 to 90 percent of the crimes in the large cities are committed by bare-branch migrants. Over the course of history, Chinese rulers’ response to the bare branches was to battle them, expel them or co-opt them as soldiers. All Chinese governments have understood that the bare branches are a formidable club — if it is in your hand it can be useful, but poised over your head it is a serious security threat.

“Indeed, the very type of government to which a nation can aspire is affected by a sex ratio abnormally favoring males. History demonstrates that such societies cannot be governed by anything less than an authoritarian political system. Furthermore, high-sex-ratio societies typically develop a foreign policy style crafted to retain the respect and allegiance of its bare branches — a swaggering, belligerent, provocative style….”
