Check out the latest in cross-cultural psychology! I show evidence that underrepresented groups like Tibetans, Papuans, Sherpas, Amish, Finns, Nepalis, Mongols, and many East Asian groups have the ideal personality complexes for space and mars missions.

Are calm introverts (like East Asians) uniquely suited for Space travel & Mars missions?

Why deep space programs select for emotionally suppressive, agreeable, hardworking introverts

I am the author of this paper. You are invited to write a rebuttal or provide counterevidence. There's plenty of ad homs against me in your thread yet no counterargument or counterevidence.

Hi Kristina, bsky recommended you as an expert in Chinese philosophy. Any thoughts on this new paper proposing ecological (arctic) origins of Confucianism and Chinese thought? bsky.app/profile/arct...

Paper out soon on the effects of ancestral tropics and heat stress, and temperate habitats on other major ancestry folks

Perhaps humans do not perceive life & our modern world as it is, but rather as a cumulative reflection of all the diverse habitats our ancestors survived in.

The well known distinctly EA combo of sociocultural problems (excessive conformity, emotional repression, death by overwork, shyness, image obsession, introversion, risk aversion, social sensitivity etc) may be mainly remnants of ancient Arcticism, & not Confucianism/agriculture.

David Sun @arcticinstincts.bsky.social · Mar 20

Is this environmental/geographic determinism? No, recent climato-econ & socioecology research shows some environments can be more deterministic than others. Especially ones like the Arctic whose selective pressures caused severe bottleneck events, and shaped morphology/genetics/medical markers.

David Sun @arcticinstincts.bsky.social · Mar 20

Are these traits genetic, epigenetic or cultural? It may be one, or a mix. Polar studies show selective pressures, but w/o future gene studies, we don't know. This paper can guide the difficult search for polygenic traits. East Asian parenting is known to transmit and enforce these traits

It already has successful predictions-

In Singapore, ethnic Chinese have only 1/6th the rate of claustrophobia vs Malays & Indians, despite all w same national upbringing/rice farm ancestry. 🌾

EA polar expeditioners have higher endurance, motivation, psych stability than N.American ones ⛷️

David Sun @arcticinstincts.bsky.social · Mar 20

Novel testable predictions- EAs will tolerate close quarters group confinement (igloos/tents) better & have more Arcticist traits vs other ancestry ppl, controlled for pastoralism: Mongols vs Cossacks, Berbers, Somalis- & rice farming: South🇨🇳/🇯🇵/🇰🇷 vs Indians, Malays, N.Italians.

David Sun @arcticinstincts.bsky.social · Mar 20

Confucianism revived preexisting Zhou dynasty values, can't act as sudden cause of EA personality. 🍚Rice farming induces collectivism but can't extend to North China, Mongolia, Tibet, Manchuria, Inuit

Indian/N.Italian/Iranian/Malay rice farmers general psych differs from EA

1

David Sun @arcticinstincts.bsky.social · Mar 20

Thus Arcticism is a parsimonious theory for paleo-origins of general EA psych, before adding on later Holocene individualism effects of pastoralism🦌 on Mongols/Tibetans, & collectivism effects of agriculture🌾 on Han Chinese, Japanese, Koreans- leading to further local variation

David Sun @arcticinstincts.bsky.social · Mar 20

Polar psychologists found the same traits to be adaptive & linked to success, & opposite traits to failure. The results are so consistent they've been refined into polar personnel selection criteria used in 🇺🇸🇨🇦🇳🇿🇩🇰🇳🇴 polar programs- mirroring ancient natural selection for traits

David Sun @arcticinstincts.bsky.social · Mar 20

EAs & Inuit share traits of notably high emotional suppression, ingroup harmony & unassertiveness, indirectness, introversion, perseverance, self-consciousness, social sensitivity, risk aversion, visuospatial IQ, & worldviews. But does the Arctic cause this in polar workers? ❄️

1

David Sun @arcticinstincts.bsky.social · Mar 20

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

David Sun @arcticinstincts.bsky.social · Mar 20

EAs mainly descend from Ancient Northern East Asians around the Ice Age, w cold adapted bio/genes: high epicanthic eyefolds, PAC glaucoma, long torso/short lower limbs🏋🏻‍♂️, lighter skin, EDAR V370A, LEPR, TRIB2, ABCC11, CGC-type, FADS, ADAM17 etc. But how about psych adaptations🤔?

1

David Sun @arcticinstincts.bsky.social · Mar 20

Out of Africa human migrations are used in bio/genetics (but not psych) to model adaptation to ancient environments, like lactose tolerance🥛, metabolism. My method reviews studies of local workers & indigenous ppl to see if local ecology induces/selects for specific psych traits

David Sun @arcticinstincts.bsky.social · Mar 20

On a hike in the Peruvian Andes, I met a Native American (NA) lady who had identical looks, gait, & vibes as my East Asian (EA) mom. Why? I later learned EAs & NAs share Siberian ancestry & had an epiphany. A hypothesis was born.

What if EA psychology was also shaped by Siberia?
