I have said before that no currently popular ideology acknowledges well-established results of behavioral genetics, quantitative genetics, or psychometrics. Or evolutionary psychology.
What if some ideology or political tradition did? what could they do? What problems could they solve, what capabilities would they have?
Various past societies knew a few things along these lines. They knew that there were significant physical and behavioral differences between the sexes, which is forbidden knowledge in modern academia. Some knew that close inbreeding had negative consequences, which knowledge is on its way to the forbidden zone as I speak. Some cultures with wide enough geographical experience had realistic notions of average cognitive differences between populations. Some people had a rough idea about regression to the mean [ in dynasties], and the Ottomans came up with a highly unpleasant solution – the law of fratricide. The Romans, during the Principate, dealt with the same problem through imperial adoption. The Chinese exam system is in part aimed at the same problem.
Every society, then and now, selects for something, but it’s hard to believe that selection pressures were deliberate choices, part of some long-term plan. Many past societies would have understood the notion of deliberately breeding people for certain qualities, but I don’t see much sign that anyone ever actually did it, not least because it would take longer than a human lifetime. Now today we could do a much better job: we have a quantitative theory of selection, buttressed with a detailed understanding of genetics, both routinely used in animal and pant breeding. At the same time all the powers that be plotz at the mere mention of selection on humans. Cause they’re nuts.
At least some past societies avoided the social patterns leading to the nasty dysgenic trends we are experiencing today, but for the most part that is due to the anthropic principle: if they’d done something else you wouldn’t be reading this. Also to between-group competition: if you fuck your self up when others don’t, you may be well be replaced. Which is still the case.
If you were designing an ideology from scratch you could make use of all of these facts – not that thinking about genetics and selection hands you the solution to every problem, but you’d have more strings to your bow. And, off the top of your head, you’d understand certain trends that are behind the mountains of Estcarp, for our current ruling classes : invisible and unthinkable, That Which Must Not Be Named. .
