Kissing cousins are bad for democracy?

This article examines the hypothesis that although the level of democracy in a society is a complex phenomenon involving many antecedents, consanguinity (marriage and subsequent mating between second cousins or closer relatives) is an important though often overlooked predictor of it.

…The data suggest that where consanguineous kinship networks are numerically predominant and have been made to share a common statehood, democracy is unlikely to develop.

Possible explanations for these findings include the idea that restricted gene flow arising from consanguineous marriage facilitates a rigid collectivism that is inimical to individualism and the recognition of individual rights, which are key elements of the democratic ethos.

Furthermore, high levels of within-group genetic similarity may discourage cooperation between different large-scale kin groupings sharing the same nation, inhibiting democracy.

Finally, genetic similarity stemming from consanguinity may encourage resource predation by members of socially elite kinship networks as an inclusive fitness enhancing behavior.

A new psychology article.

I am skeptical of cross-national democracy regressions at the best of times. I will be surprised if this finding survives inspection. But it is cute and bloggy, and isn’t that what we really want from a paper late at night?

From Josh Keating’s excellent War of Ideas blog, which is worth following. One of my new favorites.

  1. If these findings do hold up, it’s fortunate for all of us that C.U.D.D.L.E. — Cousins United to Defeat Discriminating Legislation through Education — is now defunct.

    [That group really did exist, and it’s still my favorite acronym, though I never thought I’d get to use it in a blog comment…]
