POV: It is 1100 A.D. on an Indonesian island. You are a Bajau sea nomad who freedives for seafood. Your spleen is 15% larger than other locals due to a mutation in PDE10A gene. You can store more haemoglobin rich blood, letting you breathhold & dive longer. Local girls notice how much better you are at diving and hunting fish. You are about to experience natural selection

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❄️

How so?🧵👇doi.org/10.1037/ebs000…East Asian (Korean), Greenlandic Inuit, Alaskan Inuit, Siberian Yakut 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?Native American lady (not the exact one I met)
