I think he's discussing how 'regression to the mean' works. If he's right, it works the same for everyone, regardless of whether they are east Asians or Eskimos. Your question is a bit like asking how gravity works on crockery as opposed to cutlery.
Thats exactly the questions how much do they regress to the east asian mean considering that the ones who migrate to the usa are the best educated group, also chinese descendants in the uk are not near as sucefull or above the white population when it comes to intelligence compare to the ones in america
Taiwan is weird because the chinese there are from several wave of immigration, the old ones mainly from coastal South China (Benshengren) but there was also a massive wave of chinese nationalist elites that came after the Civil War (Waishengren) and that still have more political and economical power.
It is likely that Waishengren had significantly higher IQ than the general Han population of the mainland.
Just to give some ideas about what environmental variables might be at play which have been heavily documented in scientific literature premature birth, low birth weight, nutrition, and the amount of book reading that takes place in childhood. Me and my twin sister were born prematurely and with very low birth weight we are much much smaller than other family members and my twin sister seems very significantly less intelligent than my older sister. I believe factors like birth weight and the amount of book reading taking place in early childhood explain my older sister's brilliance she was a gifted child and had a higher childhood IQ than me and she's about to complete her PhD from UCLA. I think there's a connection between how she read so much as a child and her high academic performance. At the same time, I think my older sister is way smarter than both my parents she has the most prestigious education of anyone in the family.
i also took measuements on head circumference of the entire family my older sister has a much larger head than my mom despite being shorter and smaller, i also have a much larger head than my dad despite being both shorter and smaller.
me and my twin sister were born by IVF since my parents were getting old, and i had the worst birth complications since both my lungs and heart werent developed sufficiently to leave the hospital for months, and i had delays in speech which lead to a diagnosis of autism and my twin sister didnt get autism.
I asked ChatGTP, but it was too woke. So: Why does the Khmer-population in Cambodia show an average IQ of 100, while the neighboring Thai (incl Laos) and Vietnamese linger at 80? Cambodia is poorer, worse education now (and Pol-Pot slaughtered "intellectuals"), diets very similar ...
Actually, I could not replicate my "original" find; I had googled on a Company-PC. At home, I got the numbers from a fb-post as first find, all 95 (Cambodia) to 102 (Vietnam), but those numbers are "IQ Test results from the International IQ Test website", lol.
The more recent study by Richard Lynn and David Becker at the Ulster Institute for Social Research from 2019:
The results are very mixed for this country. It would be very unwise to just pick the 100 IQ study, especially given the IQs of the neighbors. Cambodia is a famously dysfunctional country, so a wiser guess maybe be about 85.
Tak! Appreciated! Even: agreed, though thinking of "famously dysfunctional countries", makes me think: Russia. ;) (otoh, having been in Russia, I tend to see ethnic Russians as a two-cultures nation, those who have tertiary degrees and those who do not.) - Hopefully, I can update on Cambodia in May. ;)
I've wondered before how much the Cambodian genocide as a selective event affected the Cambodian population. 25% of the population died, and intellectuals and the wealthy were disproportionately targeted. How different were the IQs of those who survived vs. were killed? Of course there would be some regression to the mean back upwards afterward. Perhaps there are other traits that were selected for as well. Apparently they killed people who wore glasses for seeming too intellectual; is myopia less common in Cambodia now than it was before?
Never mind; I answered my own question. If you killed off the top 25% of a population by IQ, the mean would only alter by an IQ point or two immediately. Then regression to the mean would bring it back up to even less. Presumably the Cambodian genocide was not precisely targeting the top 25% and was only moderately correlated with intelligence, so the shift would be even smaller.
The situation is trickier than it might have been a few decades ago, seeing as the generations in question aren't as numerous as they could have been. Mass migration makes the situation even worse.
What about east asians?, specially taiwanese who are the most educated group

Is the Khmer number a fluke/fake?
Where did you find 100 IQ for Cambodia?
Cambodia 99.75 / Thailand 88.87/ Laos 80.99 source: https://worldpopulationreview.com/country-rankings/average-iq-by-country

2.3.18. Cambodia (KHM)
Fergusson, Bonshek and Le Masson (1995, Table 1) reported an
uncor. IQ of 71.50 on the CFT for a sample with a mean age of
18.81y from Phnom Penh and Prey Veng. After a reduction by
10.92 and 2.50 for FE- and country-correction a cor. IQ of 58.08
remained.
A raw score of 45.04 at the SPM was reported for a sample with
a mean age of 19.92y by Janssen and Geiser (2012, Table 1), which
has to be converted to an APM-raw score of 11.84 at the 9.58th
GBR-P and equivalent to an uncor. IQ of 80.41. A reduction by
0.21 for FE-correction resulted in a cor. IQ of 80.20. A report of
this study is also given by Lynn (2014).
A new study from Bakhiet et al. (2018, Table 1) reported SPM+
results of a normative sample from Phnom Penh. The samples’ age
ranged from 6.00y to 18.00y but was reduced by us to 7.00y to
18.00y due to missing British norms for 6.00y olds on the SPM+.
The rest had a mean age of 12.50y and obtained a raw score of 32.68
at the 55.01st GBR-P and equivalent to an uncor. IQ of 101.89, from
which 0.21 had to be subtracted. So, the cor. IQ is 101.68.
The unweighted national IQ of Cambodia is calculated as 79.99
but 99.75 if weighted for sample size and data quality. This is
simultaneously the final national IQ because no school assessment
study results were available for this country. - end of quote -

We do not want to be replaced. Period.
Have kids then, all of "you". And you are safe from replacement.
Typical response. You know, on the macro level, the amount of children a population will have is a matter of resources and pressure from outside.
On the individual level, you are right. But, on an aggregated level, you are wrong.
The situation is trickier than it might have been a few decades ago, seeing as the generations in question aren't as numerous as they could have been. Mass migration makes the situation even worse.
Who are you ?
