1500 Year Experiment on Effects of Inbreeding

Inbred Islam vs. the Outbred Western World

Healthy unrelated parents have an estimated chance of two to four per cent of having a child with a genetic disease, developmental problem or congenital defect. In contrast, in consanguineous marriages the risk is five to seven per cent, depending on the degree of the relationship between the parents and their ethnicity (2). __ Source

For almost 1500 years, Islam has allowed first cousin marriages. The result of this policy is clear across the middle east, North Africa, and in other parts of the world where Muslims practice inbred marriages.

A Danish news outlet titled Jyllands-Posten released information in 2009 concerning the astonishing rate of stillbirths, physical deformities, and various mental diseases caused by the ever-imminent incest-filled landscape in the Muslim world, concluding that Pakistani, Turkish and Somali women are twice as likely to experience complications during childbirth. Nearly 70% of Pakistanis are the product of inbreeding in Islam, mostly due to the Muslim tradition of marrying cousins via choice or arrangement. BBC also released a study, revealing that approximately 55% of Pakistani immigrants in Britain were married to a first cousin and that Pakistani-British were “at least 13 times likely to than the general population to have children with recessive genetic disorders.” __ https://steemit.com/politics/@squawker.org/inbreeding-in-islam-over-70-of-muslims-are-the-product-of-incest

In the western world, the Roman Catholic Church banned marriage “within families,” making inbreeding much less common in areas controlled by the Roman church.

… sometime around the sixth century C.E., the early church started to formulate strict marriage rules and become “obsessed” with incest, Henrich says. Historians aren’t sure why, although some religious thinkers of the time connected incest with the spread of the plague.

Lesser prohibitions against incest were already swirling around Europe when the church fathers formalized their marriage and family program. The new regulations prohibited people from marrying their first and second cousins and banned the practice of levirate marriage, in which a widow must marry her dead husband’s brother. “That part of a wedding where the officiant asks, ‘Does anybody here have any objections?’ goes back to the church asking, ‘Does anybody here know if these people are cousins?’” Henrich says. __ https://www.sciencemag.org/news/2019/11/how-early-christian-church-gave-birth-today-s-weird-europeans

The different policies on inbreeding apparently caused greater differences between these parts of the world than just the different prevalence of birth defects. The differences also may have affected the entire psychologies of the regions, and helped propel one region (Europe) to prosperity and grand innovation, while dooming the other populations (Islam) to perpetual backwardness.

A recent study in Science looks closely at psychological differences between people living in areas with high rates of cousin marriages vs. people living in areas with low rates of cousin marriages.

Globally, we show that countries with longer historical exposure to the medieval Western Church or less intensive kinship (e.g., lower rates of cousin marriage) are more individualistic and independent, less conforming and obedient, and more inclined toward trust and cooperation with strangers (see figure). Focusing on Europe, where we compare regions within countries, we show that longer exposure to the Western Church is associated with less intensive kinship, greater individualism, less conformity, and more fairness and trust toward strangers. Finally, comparing only the adult children of immigrants in European countries, we show that those whose parents come from countries or ethnic groups that historically experienced more centuries under the Western Church or had less intensive kinship tend to be more individualistic, less conforming, and more inclined toward fairness and trust with strangers. __ https://science.sciencemag.org/content/366/6466/eaau5141

The personality traits of individualism, nonconformity, and an inclination to fairness and trust of strangers, are associated with what the authors call “WEIRD (Western, educated, industrialized, rich and democratic)” cultures. These cultures might be considered “weird” because they led to a great divergence of wealth and achievement between western nations and other parts of the world between the years 1500 and 1980.

To test for willingness to help strangers, for example, they collected data on blood-donation rates across Italy, finding a correlation between high donation rates and low cousin-marriage rates. With their kinship intensity index, Schutz said, they can also predict which diplomats in New York City will or will not pay parking tickets: Those from countries with higher rates of cousin marriages are more likely to get a ticket and less likely to pay one.

And, although willingness to trust strangers, as opposed to family or neighbors, is associated with higher levels of innovation, greater national wealth, and faster economic growth, which factor causes which is not yet known. __ https://phys.org/news/2019-11-incest-dawn-individualism.html

The great divergence of Europe from the rest of the world has never been satisfactorily explained, but a large number of scholars and authors keep trying to explain it, with greater or lesser success:

This latest theory regarding consanguineous breeding suggests a new facet of the complex issue, which may well explain a portion of the differences in societal outcomes.

Demographic Decline of Islamic Fundamentalist Societies

The absolute numbers of people living in fundamentalist Islamic societies such as Pakistan have risen, but the “quality” of their achievements has not. Pakistan is poor and human misery is rampant. Pakistani Muslims flee to the west for a better life, but they often bring their dysfunctional lifestyle choices with them. In this way they limit themselves and their progeny to less benefit from the migration than they might otherwise have enjoyed.

High levels of birth defects are punishment enough for such societies, but the additional penalties brought on by personality traits that lead to low levels of prosperity, intelligence, and innovation add great insult to previous injury.

Perhaps we should not be surprised that cultures which have cursed themselves with the inability to compete with other cultures, might be reduced to religious fanaticism and violence — which is clearly the case in nations from MENA to South Asia to Southeast Asia and Central Asia.

The 1500 Year Experiment Continues

Western countries continue to experience innovation and general prosperity, while Islamic nations tend to experience high levels of violence, poverty, and human misery. Much closer scrutiny to the differences will need to be applied in order to attribute the phenomena to their disparate causes. But it is unclear why Islamic fundamentalist nations would want to continue a policy that leads to higher rates of birth defects when practiced at high prevalence rates. And even if the personality effects mentioned in the study above are only weakly linked to consanguineous marriages, the associated decay of these societies should be enough to give religious and political leaders in these countries reason to consider a change in policy.

    “Pakistani Muslims flee to the west for a better life, but they often bring their dysfunctional lifestyle choices with them.”

    Interesting! People make the same comment about Californians fleeing to other places from the hell they have created in their once Golden State. The verb is “Californicate”.

    To clarify this issue kinship based societies tend to encourage breeding within kinship groups including first cousin marriage. This causes various genetic problems but this is not the cause of the low trust nature of their societies. Rather it is the kinship orientation of these societies which directly cause a low degree of trust and cooperation regardless of the extent of first cousin marriages.

    The anthropologist Peter Frost has a interesting blog in which these issues are discussed. One thing I picked up from reading this blog is that although non-kinship individualistic societies like those found in Western Europe may well have advantages in economic competition with kinship based societies nevertheless when kinship based groups and non-kinship groups exist side by side in the same society it is the kinship based groups which may have the advantage as the members of non-kinship individualistic groups are relatively isolated and vulnerable to facing attack without receiving much assistance from other members of their group.

    In Western Europe the immigrant kinship groups gang up against native European individuals who however do not receive much support from other native Europeans. Instead the natives increasingly retreat from immigrant dominated areas and cede more and more of their country to the immigrant invaders.

    The individualistic nature of Western Europeans may tend to produce high levels
    of trust resulting in a society composed mostly of Western Europeans being economically highly productive. But the very characteristics of Western Europeans which make such Western European societies so advanced may be disadvantageous in a multicultural society with intense internal conflicts between different groups. Western Europeans may be poorly adapted to such multicultural societies in which strong group cohesion may be the most important trait of a group.

      Thanks for the comment.

      It is not entirely clear to what extent consanguineous mating selects for kinship orientation vs. the extent that kinship orientation selects for consanguineous mating. Each vector is at play. Culture is always influenced by allele distribution. 1500 years and counting . . .

    Nowadays, WEIRD countries are not defending their borders or their citizens, and are being invaded by inbred Muslims. Considering that native Europeans are being subjected to outright physical attack, and that the inbred invaders cannot even be criticized, I should think that it is WEIRD that is nonadaptive. Whatever their disabilities, the Muslims have a fair chance to takeover some countries, especially the Nordics and Finns.

    In the US, cousin marriages did happen but not in the numbers of these other cultures. I would guess just about everyone’s family tree has a cousin marriage or two from way back when one could not travel and you were kind of stuck to the farm and surrounding area for a few miles. Cousin marriages were present a handful of times in my family tree over the decades.
