a recent working paper by Nico Voigtländer and Sebastian Ottinger of the University of California at Los Angeles argues that leaders’ impact can indeed be isolated—thanks to the genomes of kings like Charles.

In theory, each round of inbreeding should have made monarchs slightly stupider—and thus worse at their jobs. This yields a natural experiment. Assuming that countries’ propensity for incest did not vary based on their political fortunes, the periods in which they had highly inbred (and probably dim-witted) leaders occurred at random intervals.

The authors analysed 331 European monarchs between 990 and 1800. They first calculated how inbred each ruler was, and then assessed countries’ success during their reigns using two measures: historians’ subjective scores, and the change in land area controlled by each monarch. The authors only compared each ruler against their own country’s historical averages.
