the awesome epigone has found a correlation of .44 between the amounts of (mostly) current consanguineous (first-/second-cousin) marriages in various societies as indicated by the data available on consang.net and perceptions of corruption by the people in those societies as found by transparency international (thnx, a.e.!). that’s higher than i would’ve guessed beforehand — i gave a bunch of reasons for that over @m.g.’s place which the epigone included in his post, so i won’t bother repeating them here.
i know that correlation is not causation, but it does “waggle its eyebrows suggestively and gesture furtively while mouthing ‘look over there,” so i’ll bet anyone a nickle — no, a dime! — that there is a connection here (and that connection is altruism/other innate social aptitudes [pg. 329+]).
i think audacious’ correlation would be even larger if there was some time depth to the inbreeding/endogamy data. what i’d like to see is:
– all the genes for altruism (and other innate social aptitudes) in man discovered so we (meaning teh scientists) can see the hbd differences in altruism, etc., in different populations and trace the evolutionary histories of all these genes in different populations. then someone could check for correlations between the gene frequencies and corruption (and other neat behaviors like nepotism).
in lieu of that, what i’d like to see is:
– all, or at least lots, of the people on the planet getting their dna sequenced so we (meaning teh scientists) can work out the degrees of relatedness within different populations so we (meaning teh scientists) could at least guess at the evolutionary histories of all these genes for altruism. then someone could check for correlations between the actual degrees of relatedness in different populations and corruption (and other neat behaviors like nepotism).
in lieu of that, what i’d like to see/do is:
– what the audacious epigone did but just with some time depth added to the inbreeding/endogamy data. plus, also, some consideration given to the fact that some forms of cousin marriage (i.e. fbd marriage) amount to more inbreeding than other forms of cousin marriage (e.g. mbd marriage).
for example, maybe two points could be awarded for each (likely) generation in which consanguineous marriages were common (haven’t considered what the cut off oughta be), and one point for each (likely) generation of endogamous marriage. zero points for marrying out. bonus point for fbd marriage. add ‘em all up and then compare/contrast with corruption, et. al.
the problem is figuring out exactly how much inbreeding happened at any given point in the past for a population. i know there are ways to get at it by looking at dna — maybe what should be looked for are any correlations between runs of homozygosity in populations and corruption, etc. that would still be looking at a sort of proxy for the presence/frequencies of different sorts of genes for altruism, but it might be interesting anyway.
