The author of the study believes the differences shown make polygenic risk assessment a bit absurd, as "The distributions of scores for African and European subjects hardly overlapped." https://www.biorxiv.org/content/biorxiv/early/2018/03/23/287136.full.pdf …

I don’t believe it’s absurd. I think that what you’re ultimately seeing in that figure is a measurement is each population's disposition toward a dopamine mediated sensation seeking, a rough measure of extraversion and "interestingness".

Blacks are relaxed, fun, creative. All these traits contribute to their tendency to hit on anything nearby that looks even remotely like a woman. In evolutionary terms this is obviously adaptive; it requires no special explanation. What does is why everybody isn't like this

The answer is that such extreme sensation seeking is mediated by dopamine (Parkinson's patients taking big doses of l-dopa often become compulsive gamblers and sex addicts) and excessive dopaminergic transmission so easily degenerates into schizophrenia.

There are three dominant factors that determine schizophrenia prevalence around the world: latitude, fish consumption, and rural vs urban living. Blacks are "black" behaviorally because in their natural environment no one else had a stronger dose of all three protective factors.

Latitude (not temperature) is the most powerful predictor of schiz because of its association with sunlight and vitamin D. New York is much colder than London, but it’s London that’s experiencing a schizophrenia catastrophe among its black population.

I think all the risk factors also here apply to homosexuality, as I’ll talk about more about later: farm boys aren’t just pretending; they really are less gay than the rest of you. This set of risk factors also goes some way toward explaining very high homo rates in Jews.

Minorities have a higher risk of developing schizophrenia everywhere and a smaller minority they are in their city the greater their risk. Ethnic and cultural homogeneity reduces feeling of paranoia and distrust: the Amish do not see conspiracies everywhere.

The last important variable is fish consumption, mediated by the extraordinarily powerful anti-psychotic effects of EPA-DHA. There is no reason everyone on earth should not take fish oil, particularly high risk groups like West Africans in Britain.

Iceland is almost in the Arctic Circle and yet their schizophrenia prevalence is actually lower than the European average because they eat even more fish than the Japanese.

Finns have consistently the highest schizophrenia rates of any European people because they live so far north and yet, unlike the Scandinavians, they stupidly don't eat fish.

That’s the origin story of how they came to be this way but I’m going to transition now into to explaining how dopamine explains a cluster of physical and behavioral traits in blacks: explosive movement, thick and dry skin, and thick hair/eyebrows.

A quick word on dopamine: the positive symptoms of schizophrenia are treated by dopamine lowering anti-psychotics. Dopamine is often misunderstood as a pleasure neurotransmitter but it really mediates movement, specifically the will to move.

I read a paper by a doctor who prescribed anti-psychotics all the time and decided to try one himself at his university. He immediately lost the will to keep working, drove home and collapsed into an armchair for hours.

In the old days before L-DOPA, Parkinson’s patients were reduced to hobbled human statues, sitting alone all day doing nothing. There are however anecdotal reports of them all of a sudden springing into action to escape fires then immediately becoming immobile once out of danger

I have taken and am taking L-DOPA (I wouldn’t be writing these furious tweetstorms without it). The first weird thing that happened to me when I started was that I began to spontaneous tap my fingers, at first for no reason but then whenever I heard music.

I honestly didn’t know this, but finger tapping tests are the primary way to measure L-DOPA effectiveness in Parkinsonian’s patients. In addition to the tapping, my reflexes became faster and running all of a sudden became fun because I seemed to bounce off the pavement.

A lot of armchair racial theorists think that athletic differences between blacks and whites are due to T, but the literature there shows there either very little or no gap at all between races.

Blacks have longer arms and legs and lower body fat, which their climate allows. But the primary athletic advantage they enjoy is dopamine mediated burst speed.

Blacks have an athletic advantage in almost in almost every big money sport, but the sports that most reward violent, schizophrenic bursts of speed are boxing and basketball.

The next thing I noticed in my Dopaquest was that about a week in my hair had become as thick as it was when was a teenager and then it kept getting even thicker. My eyebrows also became thick and conspicuously dark.

Blacks have higher pulses of growth hormone than whites do and much of what makes their appearance distinctive is similar to changes seen in acromegaly: thick hair and dry skin, loud, deep voices, large hands.
