Steven Pinker examines some very controversial study results: THE LESSONS OF THE ASHKENAZIM - Groups and Genes
Does this mean that Jews are a nation of meinsteins? It does not. Their average IQ has been measured at 108 to 115, one-half to one standard deviation above the mean. But statisticians have long known that a moderate difference in the means of two distributions translates into a large difference at the tails. In the simplest case, if we have two groups of the same size, and the average of Group A exceeds the average of Group B by fifteen IQ points (one standard deviation), then among people with an IQ of 115 or higher the As will outnumber the Bs by a ratio of three to one, but among people with an IQ of 160 or higher the As will outnumber the Bs by a ratio of forty-two to one.

Comment Info and Policy:
1) You must have Javascript enabled in your browser in order to comment (blame the spammers). If you don't know what that is, you're probably fine.
2) HTML is on, so basic html should work. Raw links will be made auto-clickable, too, so even if you don't know html you can just paste in the link and it should work fine. Keep the "http://" in it.
3) Comments are generally unmoderated, which means I don't necessarily agree with the tone and tenor of everything posted. In fact, sometimes people post things they don't really mean just to make other people look bad. The internet is an anonymous place for the most part. That said...
4) I welcome you to post here. I'd love to have your input, agree, disagree or just offer a different data point, really. If I didn't want any participation, I'd turn off comments. Be aware, however, that this blog and the comments section exist for my entertainment. Therefore, I reserve ALL RIGHTS here, including the right to remove any or all comments on nothing more than a whim. Please don't even bother complaining. I'm the one providing the space and the free news and thought buffet. I don't owe anyone anything.
Anyone who posts here will be treated as my guest. That means I'm happy to be polite as a default, but if anyone is rude to the host they'll be unceremoniously shown the door.
It may pay to recall a famous line from the Tom Selleck magnum opus, Mr. Baseball: "Jack-san, you want Yoji's advice about the babes, you come to Yoji with respect."
5) Enjoy your stay!
Link comes to a TNR page with nothing?

OK, I will risk the wrath of the TNR legal department and paste it into the forum:
