Hmm, you have a population of people. You measure something (IQ, weight,
liking of icecream). Of course there is a group mean, no matter how big
the group is. And that group mean might very well be a decent predictor
of things when comparing to other groups even if the test is lousy.
While Lynn and Vahanen's original study was pretty crappy, their data
does work surprisingly well as a predictor of a lot of things (and some
temporal changes seem to be good predictors of changes in other
important variables). That is in itself curious, even if one does not
think they are measuring real intelligence differences. Newer and better
data seem to follow the same pattern, whatever it means.

Actually, measures of state IQs in the US also show that some states are
retarded. Is that a reason to say that those differences do not tell us
*anything*, or to conclude that maybe state IQ is not really the same
thing as an individual person's IQ?
