Can we assign an average IQ for every autosomal admixture to calculate a population IQ ?

[Ibericus]

This is based on actual IQ test, not on academic performance. If somebody has the time, he can do a correlation matrix of EEF, WHG and Steppe , but I don't see any correlation, there is a lot more going on than that: you have Rome and Lisbon above Oslo or Copenhagen , and for Paris at the bottom we know the reason , so:

If those IQ results are correct why do they not translate to the population having reached a certain level of educational attainment? The reason being some of the results about nations IQ results are erroneous. When were the tests conducted and by who? Are they current? Something is obviously not correct in those IQ results.



Also PISA results.

There are numerous other results which I could post to show that there is something odd with those IQ results for Ireland in particular. How is Ireland performing better academically than populations that apparently have higher IQ?

Canada?.... really??

[Quote tita: I read studies showing that a child from one parent white and the other black would have a average iq between white iq and black iq, so why would not it be true for autosomal admixtures too ?]

IQ is only 80% genetic, and the other 20% regresses toward the mean. To account for this, subtract 100 from the average parental IQ, multiply it by 0.8, and add it back to 100 (or subtract it from 100, if it was below 100).

So 110 regresses down to 108, and 90 regresses up to 92, both toward 100.

But of course, this is just their children's predicted average IQ, and is inaccurate for a single child. It becomes more accurate the more children they have, and the more you know about the parents' parents' IQ, etc., because the children's IQ will regress toward their average ancestral IQ, not necessarily toward 100.

Exactly (the bold) and an important aspect for the understanding. Btw. the regress towards the mean is also "genetic".

Considering that tita's quote refer to averages it should be essentially applicable (left aside peculiarities of dominance and recessiveness that may make the average of the mixtures, particularly first degree ones, not behave symetrically in between the parent pops).

As for such old contributions as WHG, ENF, CHG, EHG etc. I consider it pointless to connect them with a particular IQ average (albeit they will have exhibited differences, ofc.).

Why?

Because since these times the various mixed by them populations have experienced so much additional evolution (selections, genetic drifts), that these effects dwarf the importance of the mean IQ of the source populations 10 ky ago. All of these source populations will in their gene pool have provided also genetics for higher intelligence.

The fact is that mainly the women of the EEF have gone to the north and east. Women are hardly the smartest part of humanity. Therefore, northern and eastern Europe got its intelligence from the Yamnaya culture and ehg. Southern Europe from the eef. It is not known which of them is smarter.

Not every test can be standardized and ascribe to a bell curve. Asking to add single digits or to recite a national alphabet forward which most people have memorized would give approximately the same response in over a very wide range of cognitive ability. The distribution would be quite flat.

The issue with these examples is they aren't even tests, unless you're testing how many examinees are still breathing. It is easy to come up with pointless counterexamples of this nature, like a test with only a single item that asks, "If I flip this coin, will it lands heads or tails?"

By the way, I'm confident there is little in this thread that hasn't already been done to death by https://substack.com/@kirkegaard.

Ireland is a tax heaven in the European context, if anything it's a testimony against socialism with a few culprits. But i agree i don't see any reason Ireland would be any significantly different IQ wise than UK.

Because they don't have a low IQ

Canada?.... really??

Apparently our Math requirements in High School is pretty intensive. My teacher said that if we even manage to pass our Grade 12 Math class that we would be considered above average, this was not an AP class or anything. I mean, there are alot less flat earthers in Canada than America, so...
