This is an interesting and somewhat provocative piece from the AAAS ScienceMag.org And if you're not familiar with the acronym WEIRD as I was, it stands for Western, educated, industrialized, rich, and democratic.https://www.sciencemag.org/news/201...ian-church-gave-birth-today-s-weird-europeans
In September 506 C.E., the fathers of what would later become the Roman Catholic Church gathered in southern France to draw up dozens of new laws. Some forbade clergy from visiting unrelated women. Others forbade Christians from marrying anyone more closely related than their third cousin. The authors of a sweeping new study say that last, seemingly trivial prohibition may have given birth to Western civilization as we know it.
...
The church’s early ban on incest and cousin marriage, the researchers say, weakened the tight kinship structures that had previously defined European populations, fostering new streaks of independence, nonconformity, and a willingness to work with strangers. And as the church’s influence spread, those qualities blossomed into a suite of psychological traits common today across Western industrialized nations, they argue.
...
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.
Centuries living under these restrictions fundamentally reshaped European societies’ kinship structure—and their psychology, the authors say. Traditional kin networks stressed the moral value of obeying one’s elders, for example. But when the church forced people to marry outside this network, traditional values broke down, allowing new ones to pop up: individualism, nonconformity, and less bias toward one’s in-group.
