If that's true, then better get ready to accept the inevitable hegemony of Hong Kong, Korea, Singapore, Japan, and China, which beat whitey-white nations like Iceland by 4 to 8 IQ points.

But where do you get that whites average 105? The best Ive found is that the whitest countries (like Switzerland, Norway, etc) cluster at 100.

Look into how infant stimulation, early childhood nutrition, and rich social interaction boost IQ.

I don't deny that there's a genetic component to intellectual development, like ANY development. But nurture plays a big role here. When Ireland was dying of famine 170-180 years ago, the British thought the white-as-can-be Irish on a level with apes.

So: hard to explain the "Celtic Tiger" phenomenon.

“which beat whitey-white nations like Iceland by 4 to 8 IQ points.”

Yes, they did, but 4-8 points is noise not a competitive difference.

Good post.

I think that the activities of the Jewish people and the Chinese, coupled with bilingual (Hebrew + a mother tongue) Bible scholarship and an intricate written language, respectively, have had a compounded beneficial effect on both of those people groups (in general).

(Long run on sentence, I know, sorry for that.)
