This post is going viral, so I decided to dig into the question of why homosexual relationships dissolve more frequently, and especially lesbians. This is the original figure from the study. This shows us that formal unions are much more stable, not so surprisingly. Note the lack of error bars.

Using data from across the world, we estimated the speed of selection against intelligence across countries. There is a certain regionality to the data

Some big accounts as asking why so many MAGA types are suddenly so very anti-Indian, considering that Indians in the US and to some degree in the rest of the West, are model immigrants (high performance, low crime). The main answer is not difficult to understand.


This answer is based on the typical finding of sociology. In terms of partisanship, whichever groups in society you dislike is just the ones you perceive to be most different from you politically. Brandt and colleagues worked this out in 2014.

Maybe you've seen a map like this one. It gives one the impression that Europeans were uniquely or particularly evil regarding slavery, in this case of Africans. However, slavery was more or less a human universal. Pre-Columbian Americas, ancient China, or the Islamic world.

So why are man still explaining things to women? It's a mystery. link.springer.com/article/10.102…

Lewis Terman thought that the average American would be a believer in egalitarianism regarding sexes, races etc., and that was in 1922. archive.org/details/worlds…

New study of 2700 Indian whole genomes shows that Indo-European/Yamnaya/Steppe is quite low, about 15%. It is a bit higher in the north (almost 20%) and among those who speak IE languages, but not impressively so. Too much mixing since the arrival. Inbreeding is strong. The median person had identical blocks in their genome at the level suggesting their parents were 3rd cousins, whereas the human average is about close to 4th cousins (Africans less).

Not everybody commit scientific fraud at the same rate. Let's look at some data. First retraction rates. We can also look at the top list of most fraudulent researchers ever (so far those that were caught). Note: data from 2019 list. There's quite a few non-Europeans.

You have maybe seen this plot. It shows ratings of races in USA by race. The key result is that each race favors their own, except for Whites who are apparently race-blind. Since it only covered a single year, 2020, I wondered if this would replicate across years of data. So I downloaded the data for 1964-2024.

So we see that the result replicated (I didn't use survey weights). And indeed, in 2020 and 2024, Whites have about zero ethnocentrism.

Mental issues roughly follow a hierarchical pattern, like cognitive abilities, like a general factor on top. At least, statistically. The motivating factors behind this approach compared to the categorical (diagnostic) approach are: 1) evidence of continuity between clusters, 2) binary encoding of continuous data loses information, 3) correlations among diagnoses are the norm, 4) a given person may not quality for any particular diagnosis, yet have severe symptoms.

Danish cheap energy fan @BjornLomborg posted this recently. There's a strong correlation between solar+wind% production of electricity and the prices. Is this causal? I downloaded data for 130+ countries, an these are the distributions of renewables for the rich world countries. Denmark is unfortunately number 1 for wind power.

We just published a study showing that national stereotypes of intelligence are also accurate. It looks like this. You may be able to see that the pattern is quite nonlinear, and a spline test confirms this.

It looks like the more women we get into academia, the less of a university it will be and the more of a left-wing emotional playground it will be. emilkirkegaard.com/p/who-values-a…

US Naval Academy: "a white applicant with a 5% chance of admission would have a 50% chance if evaluated as Black, and more than 70% of Black admits would not have been admitted under a race-neutral system"

Whites the most systematically discriminated against race. The usual SAT gaps among applicants.

Americans are super fat, so many people look for explanations for this, usually something USA-specific like seed oils, or corn syrup. Americans have some race differences too, but they aren't that large. The White Americans are quite fat by themselves, only Asians drag the mean down.

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

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… 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.

The racism of teachers In Germany, non-German students (anyone with "migration background") get lower grades and test scores.

There's a substantial sex difference in support for nuclear power, men are much more in favor (Cohen's d = 0.57). Danish data on 1-7 scale. This difference cannot be explained by age, vocabulary IQ, or even overall political ideology. Though it is interesting that age predicts support at -0.30, youth are pro-nuclear! The prediction from political ideology is insanely strong, leftism predicts support at -0.80!
