Yesterday, we reported that the U.S. is, on average, #40 in the world in mathematics.

Usual punditry is that schools are bad … blame it on the teachers.
But, I wondered: is it a bad production process (the schools) … or could it be the raw material going into the process (i.e. innate brain power).
So, the question of the day: how does the U.S. rank on IQ versus other countries?
