I’m just putting a name to something that’s been discussed to death in racialist circles. How is it that modern Scandinavians are the world’s biggest pussies, despite being direct descendants of the world’s biggest badasses?
There is no good evidence (that I’m aware of) that the gene pool involved has changed in any dramatic way since the Icelandic sagas were written, and the high average intelligence and height of Scandies suggests that they still have plenty of high-quality genes and a low mutation load. (Particularly because intelligence is very sensitive to mutation load.) There is also the curious fact that although their IQs are the same in different environments, their personalities are extraordinarily different. This contradicts the finding that personality is more robust than intelligence.
Atheists explain this as an effect of Christianity-as-slave morality (Christians blame secularism, naturally). Edenists (me, particularly) tend to attribute this to environmental effects like global warming and human domestication (i.e. civilization). Regardless of when exactly temperatures fluctuated, it is important to note that Scandinavia has been, at times, very cold (therefore producing proper cold adaptation at times). Anyway, one thing we can all agree on is it was the Joooooze.
As evidence for the edenist view, I note that Scandinavians go nuts when they live in high population density urban areas and don’t reproduce. This hypothesis could be tested easily with twin studies, and IMO definitely should be because the implications for political policy are obvious (though very different for various political persuasions). The broader, stronger hypothesis is that environment (i.e. nurture over nature) has a much stronger effect on Scandinavian populations than on other populations. E.g. An hour per day of math tutoring will produce a much stronger effect in an average Scandinavian person than in an average white person from another population, where IQ and conscientiousness are held constant.
(The same sort of twin studies ought to be done with other heavily neanderthal-influenced populations, like the Japanese, to provide evidence for or against genetic causality.)
