Original Note:
The possible implication that inbreeding would lower IQ sustainably is incorrect. First cousin marriage is estimated to lower IQ by ~3 points on average. https://doi.org/10.1016/j.intell.2008.10.007 Furthermore, matrix IQ tests on small and disadvantaged populations can be unreliable. https://doi.org/10.1007/s40806-022-00351-y
