Study: Cross-cultural genetics of g (IQ) and selection


•National fertility and country-level general intelligence (G) negatively correlate.
•The frequencies of 8 SNPs that predict IQ also negatively correlate with fertility.
•Both findings are associated with Jensen effects.
•The SNP metagene negatively predicts fertility, when controlled for HDI.
•Global G should decline due to selection by − 0.253 points per decade.

Genetics seem to be keeping K-families smaller than r-types’, enough to moderately provision each child with high investment parenting. However, the effect is mild, suggesting it prevents Malthusian exhaustion.

Victorians were probably smarter than you

I would’ve thought the successful Revolution as proof enough.

I prefer Victorian books for this reason. A book is a peek into another’s mind, and theirs are simply the deepest I have encountered.

There are other factors involved, including creativity (originality) and parallel lack of mutation load (mental disease).

I would be uncharitable for once and ascribe this experimental outcome to two common social factors;

  1. stupid people with high time preference were literally left to starve in the streets and were generally derided (social-moral influence on the weak-minded to dissuade those considering it) as grasshoppers to the smarter ants of society who made their choice.
  2. the mentally ill were thrown into asylums and much like prison used to function, this served to keep their genes separate from the common population and out of circulation as it practically barred them from reproduction (this is the true punishment intended from prison as a form that everyone seems to have forgotten).

If we brought back certain elements of these population controls, no doubt g/RT would rise.

If you want a practical guide to these questions, ask yourself where our geniuses are? They all seem to have died off in the 20th C. Where’s our Voltaire, Newton, or Emerson? Do they not exist, or does nobody pay them attention; I don’t know which is worse?

I love everything about this paper. I want to make a small altar and light a candle for this paper.


General intelligence itself is correlated with many important health outcomes including cardio-vascular function and longevity.
