EAST ASIAN VS EUROPEAN PERSONALITY DIFFERENCES
I’m still skeptical, but it appears that east asians and europeans diverged over 40K years ago – because east asians do share some of the more complex genes with europeans. But while europeans are much more neotenous than south eurasians and certainly africans, East Asians have much higher neoteny than europeans, even more so than europeans have over south asians and africans.
So there is a genetic predisposition for more childlike (meaning socially adaptive) social behavior (groupishness) than is evident in westerners – in exchange they get to live a bit longer, have a lower body mass index, have less body hair, and personality differences.
Those differences (genetic research) are in excitement seeking, empathy, the perception of loneliness, conscientiousness, and extraversion.
This genetic difference does correlate with Hofstede’s cultural Dimensions Indices.
power distance index (PDI),
individualism vs. collectivism (IDV),
masculinity versus femininity (MAS),
uncertainty avoidance index (UAI),
long-term orientation versus short-term normative orientation (LTO), and
indulgence versus restraint (IVR).
