I published a new study and it's a juicy one.

The establishment's theory of race differences in socially valued metrics is that this is due to "systemic racism", a kind of Marxist conspiracy theory where the dominant group (Whites) keeps other peoples down.

There are clear testable predictions from this theory. In places where racist, White people have more power, outcomes for non-Whites, especially Blacks and Hispanics should be worse. Recall that the US demographics by county look like this.

Of course, Republicans are racist in this theory.Image
Image
Thus, the theory predicts that in these areas of the USA, Blacks and Hispanics should be particularly worse off compared to Whites. But the exact opposite is actually true. The race gaps are smaller, not larger, in Whiter and more Republican areas.


Image
Image
Image
Image
The above figures are for test score gaps, but the same holds true if we look at social status gaps. Here's some maps of race gaps in social status.
Image
Image
So we need another way to explain the variation in social status gaps. Well, it's easy. Test scores -- academic achievement that mainly reflecting intelligence -- explain why race gaps are smaller and larger in various locations. Meritocracy works.
Image
Image
It gets even worse for the theory. It turns out the effect of White population share and Republican vote share are interactive. The areas with the smallest race gaps are the ones with the largest White populations and the largest Republican vote shares combined!
Image
Image
There we have it. The Marxist conspiracy theory that is the go-to explanation of race relations fails when we look at county-level variation across the United States. The predictions it makes are exactly opposite of reality. If anything, it seems Republican Whites are good for minorities.

You can also download the data and R code yourself if you are more curious. There are many more figures and maps in the OSF repository.

Soyboyism is also heritable. In fact, the most heritable (snp h²) dietary habit in this study! (bottom right) Image

Can Europe learn from Ghana? Buried on Wikipedia is a 3 sentence part about how Ghana deported 20% of the population -- 3 million people -- all the non-Ghanans. And it only took 3 months. The "Ghana Aliens Compliance Order" (GACO)

en.wikipedia.org/wiki/Illegal_i…Image
This website provides the history. It begins, of course, with economic migration since Ghana was the gold coast. In fact, these migrants were going into a British colony, probably for the usual reasons of wanting to live under European domain: rule of lawand prosperity. Image
Image
European rule eventually declined, and just after they left (1957), the economy goes bad. At least, so they say, but it doesn't look that way until 1970s by GDP stats. Image

The racism of teachers Image
In Germany, non-German students (anyone with "migration background") get lower grades and test scores. Image
Due to their politics, teachers are expected to have some bias towards girls, minorities, low-SES etc. students. So do they? The authors find that, yes, they do. Image

New Dutch results on immigration. Sobering as usual. There are 3.7 million foreigners in the Netherlands. Image
One can calculate a given person's contribution to the state budget by adding up all their contributions (revenue) and subtracting all of their costs. Doing so gives a net contribution metric. Dutch people are c. net 0, and the others groups net negatives. Image
There's a lot of variation though. Numbers for the first generation can be very positive or negative. It's easier to get very positive values because many people arrive after having finished their education, so begin working immediately. Many of them leave before pension too. Image

Many of you have seen this figure. A pessimist's favorite. A massive innovation decline starting from 1880 or so. Image
It fits suspiciously well with the onset of dysgenic fertility in NW Europe, or at least the UK. Image
However, does this really work this way? It's based on a 2004 book called The History of Science and Technology that recorded significant events from 3000 BC to 2003 or so. But what if the author missed newer stuff that wasn't recognized as important yet? Image
