Hans Eysenck on how THE IRISH AREN'T AS BRAINY AS THE ENGLISH... Note that the logic and supposed evidence was exactly the same as for observed IQ diff b/w "races"... (from 1971)pic.twitter.com/v39hpwfzR4

Weird way to say, “no clue, I just pulled it out of my ass”, but ok

Just to add to this you can find the same sort of arguments being made about Italian, Spanish, and other Southern/Eastern European immigrants to the United States in the 1920s. The same arguments about the gap being genetic. All the groups rose to the American average by the 50s.pic.twitter.com/q6FfV5p6Mw

As far as I know, no one has ever properly done such a study. It would also be quite difficult to do without genetic data because of admixture and the continuous stream of new immigrants from these countries and the changing selection over time.

Yes, exactly that sort of thing has never been really evaluated AFAIK. One can't just point do some prior gap that disappeared, and then assume genetics did not change. By the way, this study has pretty rigorous approach and finds ancestry matters. https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2608567 …

you didn't even read to the end of the abstract, did you?

I've read the entire paper months ago. Did you read it?

I have a strong dislike of laziness. I can't help it, genetics made me this way. ;)
