I was referring to a Griffe duLion link which I posted above. I believe I mentioned that. I believe they were looking at IQs above 120 (or was it 140?)
...and as I pointed out, not all studies agree on that point. If it was that obvious, it would be evident in multiple studies.

As you know from your study of statistics a one standard deviation at the mean will produce a bigger differential at one or two SDs above the mean.
Well, considering that "SD" means "standard deviation", that sentence is gibberish. You've lost some credibility on your understanding of statistics here. Did you mean for one of those to be the sample standard deviation and the other the population standard deviation?
Though, yes, I am being lazy and using wikipedia and generalizing instead of doing real research on the matter. Perhaps that's just my gentile heritage showing through.
You can give a man a link but you can't make him read.
The Nobels is something else though, apparantly not explainable by IQ alone. Is there a subgroup of extra high IQ performers in the mix?
Yeah. Ashkenazi Jews.
Well, I did point out a study showing an IQ of 103.5 for Ashkenazi Jews, and I did pull it from a page called "Ashkenazi intelligence". So I think you missed my point.
And of course culture makes a big difference. Which is why so many 70 IQ Jews are winning Nobels.
As you know, the world of 7 billion people has a very large number of people with an IQ of 120. So why aren't they all winning Nobels?
You certainly are stubborn, aren't you? Very topical.
Jews are about .25% of the world population and yet they win about 25% of the Nobel prizes.
From that you can infer certain things.
An average IQ of 103 does not explain it as well as an average IQ of 115.
You will excuse my poor wording in previous comments. I'm weak on stats terminology. My understanding is a little better. None the less I provide links.
