another IQ-premacist bites the dust...,

slate | Update, May 10, 2013: On Friday afternoon, after this story had already been published, Jason Richwine resigned from the Heritage Foundation.

 Four years ago, long before he’d join the Heritage Foundation, before Marco Rubio was even in the Senate, Jason Richwine armed a time bomb. A three-member panel at Harvard’s John F. Kennedy School of Government accepted Richwine’s thesis, titled “IQ and Immigration Policy.” In it, Richwine provided statistical evidence that Hispanic immigrants, even after several generations, had lower IQs than non-Hispanic whites. Immigration reformers were fools if they didn’t grapple with that.

"Visceral opposition to IQ selection can sometimes generate sensationalistic claims—for example, that this is an attempt to revive social Darwinism, eugenics, racism, etc,” wrote Richwine. “Nothing of that sort is true. … an IQ selection system could utilize individual intelligence test scores without any resort to generalizations.”

This week, Heritage released a damning estimate of the immigration bill, co-authored by Richwine. The new study was all about cost, totally eliding the IQ issues that Richwine had mastered, but it didn’t matter after Washington Post reporter Dylan Matthews found the dissertation. Heritage hurried to denounce it—“its findings in no way reflect the positions of The Heritage Foundation”—and Richwine has ducked any more questions from the press.

 His friends and advisers saw this coming. Immigration reform’s political enemies know—and can’t stand—that racial theorists are cheering them on from the cheap seats. They know that the left wants to exploit that—why else do so many cameras sprout up whenever Minutemen appear on the border, or when Pat Buchanan comes out of post-post-post retirement to write another book about the “death of the West?”

Academics aren’t so concerned with the politics. But they know all too well the risks that come with research connecting IQ and race. At the start of his dissertation, Richwine thanked his three advisers—George Borjas, Christopher Jenks, and Richard Zeckhauser—for being so helpful and so bold. Borjas “helped me navigate the minefield of early graduate school,” he wrote. “Richard Zeckhauser, never someone to shy away from controversial ideas, immediately embraced my work.”

Yet they don’t embrace everything Richwine’s done since. “Jason’s empirical work was careful,” Zeckhauser told me over email. “Moreover, my view is that none of his advisors would have accepted his thesis had he thought that his empirical work was tilted or in error. However, Richwine was too eager to extrapolate his empirical results to inferences for policy.”

Borjas’ own work on immigration and inequality has led to a few two-minutes-hate moments in the press. He wasn’t entirely convinced by Richwine, either.

“I have never worked on anything even remotely related to IQ, so don't really know what to think about the relation between IQ, immigration, etc,” Borjas told me in an email. “In fact, as I know I told Jason early on since I've long believed this, I don't find the IQ academic work all that interesting. Economic outcomes and IQ are only weakly related, and IQ only measures one kind of ability. I've been lucky to have met many high-IQ people in academia who are total losers, and many smart, but not super-smart people, who are incredibly successful because of persistence, motivation, etc. So I just think that, on the whole, the focus on IQ is a bit misguided.”

But Richwine had been fascinated by it, and for a very long time, in an environment that never discouraged it. Anyone who works in Washington and wants to explore the dark arts of race and IQ research is in the right place. The city’s a bit like a college campus, where investigating “taboo” topics is rewarded, especially on the right. A liberal squeals “racism,” and they hear the political correctness cops (most often, the Southern Poverty Law Center) reporting a thinkcrime. Fist tap Big Don.
