In one of my essays, I wrote that the position a quarterback is taken in the college draft is not a reliable indicator of his performance as a professional. That was based on the work of the academic economists David Berri and Rob Simmons, who, in a paper published the Journal of Productivity Analysis, analyse 40 years of National Football League data. Their conclusion was that the relation between aggregate quarterback performance and draft position was weak. Further, when they looked at per-play performance—in other words, when they adjusted for the fact that highly drafted quarterbacks are more likely to play more downs—they found that quarterbacks taken in positions 11 through 90 in the draft actually slightly outplay those more highly paid and lauded players taken in the draft’s top 10 positions. I found this analysis fascinating. Pinker did not. This quarterback argument, he wrote, “is simply not true.”
I wondered about the basis of Pinker’s conclusion, so I e-mailed him, asking if he could tell me where to find the scientific data that would set me straight. He very graciously wrote me back. He had three sources, he said. The first was Steve Sailer. Sailer, for the uninitiated, is a California blogger with a marketing background who is best known for his belief that black people are intellectually inferior to white people. Sailer’s “proof” of the connection between draft position and performance is, I’m sure Pinker would agree, crude: his key variable is how many times a player has been named to the Pro Bowl. Pinker’s second source was a blog post, based on four years of data, written by someone who runs a pre-employment testing company, who also failed to appreciate—as far as I can tell (the key part of the blog post is only a paragraph long)—the distinction between aggregate and per-play performance. Pinker’s third source was an article in the Columbia Journalism Review, prompted by my essay, that made an argument partly based on a link to a blog called “Niners Nation.” Read the whole thing >
