You are presumably not very interested or else you would have found the
reference by now (Sept 9th if you want to look), rather than relying on
a website publishing the ravings of someone whose distinction in
psychology is questionable.
Having looked rather briefly at the articles I would suggest that most
of the paper is a matter of technical population genetics. I think the
authors draw rather stronger conclusions than can be justified from the
sample used, and the paper has some puzzling features. The abstract
quotes a very definite age for the polymorphism, but the paper gives a
95 % CI which is (as usual) quite wide. However that will be settled by
further work by geneticists- I remember Science's well- known paper on
the 'gay gene' and what became of that.
They do not (and do not claim to) show that the variants in question
affect intelligence or brain size at all.
As to your other report, the website refers to 'Jirtle'. There is a
'Jirtle RL' at Duke who has published on IGF2R but I cannot find any
reference to thick blokes on PubMed or WOK.
Perhaps you could enlighten us when you have read the original report.
