I suppose that, to some extent, who gets credit for what isn't all that
important, but .....


When I brought up the article Tredoux referred to on the Internet, I was
interested to note that the NBA discussion paralleled my effort in Skeptic
3:3, (1985) pg 87. As far as I'm aware, that was the first time any such
calculation had been published, though if I'm wrong on that I'd very much
appreciate seeing any reference to an earlier effort. I also got the same
~0.9 SD (standard deviation) difference.


The use of AQ also sounds very much like Steve Sailer's take-off on a
similar calculation I made concerning the degree of advantage the Kalenjin
have over the rest of the world with respect to distance running. There the
difference is about 1.5 SD, and Steve ingeniously converted this to a RQ
(running quotient) of 122 -- to put it into a more familiar context. Most
people don't think in terms of SD units, but they do know about IQ.


OK, there's my complaint for the day.


Having said that, I would like Tredoux to check out my Kalenjin estimate,
especially with respect to the problem of sampling.
