Part of this is easy to explain: The United States is big. Very big. And it's a far bigger country than the other members of the OECD. We claim roughly 27 percent of the group's 15-to-19-year-olds. Japan, in contrast, has a smidge over 7 percent. So in reading and in science, we punch above our weight by just a little, while in math we punch below.

But the point remains: In two out of three subjects, Americans are over-represented among the best students.

If we have so many of the best minds, why are our average scores so disappointingly average? As Rutgers's Hal Salzman and Georgetown's B. Lindsay Lowell, who co-authored the EPI report, noted in a 2008 Nature article, our high scorers are balanced out by an very large number of low scorers. Our education system, just like our economy, is polarized.

What's the takeaway? Salzman and Lowell argue that our large numbers of top scorers should help put to rest the concern that we're losing the global talent race executives and politicians love to fret about. I'm not sure they'll do the trick, though. In 2009, Chinese students in Shanghai sat for the PISA test for the first time, and their scores were spectacular. Although data for its other mainland provinces hasn't been published, the OECD's test guru says they're similarly impressive.It seems pretty likely, in other words, that China has more young math and science geniuses at its disposal than we do (whether that's something that should be keeping any of us up at night is another issue). But Salzman and Lindsay make another point that's worth dwelling on: You can't replicate a country's style of education without replicating its culture, so instead of looking abroad for ideas about how to teach our kids, as some policy-types are inclined to do, perhaps we should look at what's succeeding here at home and spread it. Our schools are already producing plenty of bright thinkers of their own.
