When the average of ALL black people is 85, the average for adopted children are lower because once again the average adopted child comes from higher risk environments than the average.
North Korea does not have an average IQ of 98, that is an estimated number not an actual accounting because much like China, NK only self reports and in most cases iq estimates are made by regions so NK is given a higher average because they are bordered by China and South Korea. The autism rates in NK compared to SK alone squash that metric as it is one that NK can’t lie about.
Variance is higher than predictability in all of these cases. The average of 5 points difference is a huge factor when looking at genetically identical twins or genetically similar siblings.

Just say "the average of black people (in the US) is 85." The "average of all black people" means something quite different.
I'm asking what that number is, not relying on assumptions. You're claiming they are making big jumps in IQ merely through changes in environment. Show me what those jumps are, as we observing rather modest increases otherwise.
It is the estimate we have based on the evidence available. It's possible it is off, but that is conjecture, and the number presented is highly consistent with the Flynn effect. Not sure what you're arguing about in the rest of that paragraph so I'll skip responding to it.
The autism rates in NK compared to SK alone squash that metric as it is one that NK can’t lie about.
So you dispute IQ averages of North Korea, but readily accept the numbers associated with autism? Which I don't see the relevance of anyway.
Variance and predictability are not at all incongruous with each other. The predictability of genetics as it relates to intelligence is so strong on average that, if you had similarity consistent predictability in sports betting, you would quickly amass a fortune.
I can already see where this conversation is headed. The evidence has been presented for those looking to come to an understanding on this topic.
No the numbers are admittedly conjecture are the people that do the studies admit countries like North Korea are done by region averages because there is no data given by the NK government.
You mean there’s a difference between falsifiable data and non-falsifiable data?
As long as environmental factors are maintained, the second malnutrition hits, iqs drop dramatically like in the pubmed study I posted…
You can falsify an iq exam to a far easier extent than something like autism, especially when NK relies on foreign medical for the latter.
