В декабре Лейф делал анализ данных, по России вот что:
2 декабря
The Russian Aspie Quiz has considerably lower Chronbach alpha (0.9588) than the English (0.9751). The interitem covariance is also 1/3 lower (0.10 vs 0.16), and about 1/3 of the items have considerably lower relevance in Russia. I'll check the Polish dataset too which has close to 50,000 answers too and lies in between Western Europe and Russia. What this means is that neurodiversity in Russia is partly different than in Western Europe.

I got a new idea about analyzing different regions. I have 157000 English answers + another 50000 or more in experimental versions with ancestry information. Using that data it should be possible to analyze major groups like American Indians and Russians and compare them with the native language translations.

I think I might solve the issue of relatedness between populations, and especially for the native American Indian populations. I have 1076 Russian, 3873 Eastern European, 2991 Northern Indian and 542 Southern Indian answers after filtering, all which are enough to analyse how the "relevance" estimate in Aspie Quiz varies. Proof of the concept is that the Indian populations are highly related, and so is the Russian and Eastern European. It's also the case that Russians are more closely related to Northern Indians than to Southern Indians. By analysing Japan and South-East Asia I should be able to solve it. I think this is a far more useful method than analysing SNPs (mutations), as my measure relates to Neanderthal and Denisovan ancestry as a package, not on the basis of individual genes.

So, I've finished all relevant populations, and I think I have a good idea about how the traits have spread (even if it is a complex picture):
Correlation table:

There seem to be five branches: 1: Western & Northern Europe (probably the Celts) that have a unique set of neurodiverse traits. 2: A branch that comes from Northern Asia (Russia), and which has spread into Eastern Europe but also to Eastern Asia. 3: A much older branch in Southern Asia which seems to be the source population of Native Americans and North African Berbers. 4: Native Australians are part of the oldest branch, which has connections to both the Celts and Native Americans. 5: A newer branch from the Middle East that goes into much of Europe (probably closely related to #3), which probably is related to the spread of agriculture.
I think the Celt branch is related to additional hybridization with Western European Neanderthals as the Russian path spread west. That's why it has a unique set of traits. It probably existed in much of Europe before agriculture.
So, not at all like the paleoanthropologists wants us to believe it is.
My next goal is to prove that Africans have no inherit neurodiverse profile, but rather "borrows" it from surrounding populations. It seems possible that the profile of Berbers could have existed in much of Africa, but has become extinct. Something that could happen in Europe as well if the discrimination continues. In fact, neurodiversity today is almost extinct in much of South Asia and Africa.
