David Sun & Asian Race Realism
On our recent trip to the Grand Canyon, my White friends commented several times on the behavioral/personality differences between them and their East Asian wives. One jokingly said" It is a wonder we can even breed."

These types of observations beg the question, "are differences between races only skin deep?" David Sun, former researcher at the University of Washington (UW), doesn't think so.
Sun's research centers on the "Arcticism" hypothesis: the idea that modern East Asian populations (and to some extent other groups) retain psychological and social adaptations from their ancestors' habitation in harsh Arctic and subarctic environments during the Late Pleistocene (around the Last Glacial Maximum, ~20,000–30,000 years ago).
These ancient Northern East Asians, he argues, migrated southward into warmer regions during the Holocene but preserved traits suited to extreme isolation, unpredictability, and group interdependence.
I was rejected from woke PhD programs for my "un-PC" idea: ancient migrations can shape culture & psychology. So I proved it alone.

My new peer-reviewed @APA paper shows East Asian personality may stem from Ice Age Siberia ~20000 yrs ago❄️

Sun is a controversial figure in the Academic world to say the least.
Armed w @sci_hub_, I sifted 100s of obscure papers on Inuit (who share Siberian ancestry w EA) & polar workers🥶. I found despite EA psych/personality being on an extreme end of global spectrum, Inuit & successful polar staff have the same psych profile, personality, & worldviews pic.twitter.com/Ywn0oGzejz

Did arctic evolutionary pressures produce a stereotypical East Asian psch profile, personality and worldviews?
The acceptable explanation for these observable stereotypical traits is that EAs are from cultural forces such as Confucianism and rice farming.
However, rice farming cultures vary greatly and East Asian traits have existed before the time of Confucius. It appears that the acceptable explanation is made for smooth-brained nitwits by the architects of a system built for control.

Here is an overview of the reality on this topic:

Thoughts to grow on:
Do environments shape the traits of the people who evolve in those regions? If so, what are the implications for people across the world?
