A co-author of the Heritage Foundation’s new immigration report, which right-wing media have hyped despite even conservative criticism about its methodology, has long promoted inflammatory theories about the relationship between race and IQ in Hispanic immigrants, an unsurprising fact given his ties to extremist anti-immigrant organizations.
Dylan Matthews of The Washington Post’s Wonkblog reported that Jason Richwine, a co-author of the Heritage report, asserts in his 2009 doctoral dissertation titled “IQ and Immigration Policy” that “there are deep-set differentials in intelligence between races.” Matthews wrote [emphasis added]:
While it’s clear he thinks it is partly due to genetics — “the totality of the evidence suggests a genetic component to group differences in IQ” — he argues the most important thing is that the differences in group IQs are persistent, for whatever reason. He writes, “No one knows whether Hispanics will ever reach IQ parity with whites, but the prediction that new Hispanic immigrants will have low-IQ children and grandchildren is difficult to argue against.”
Matthews also included Richwine’s dissertation abstract, which forwards the idea that the U.S. should not only select its immigrant pool based on IQ, but that immigrants and their future generations are not apt to obtain his desired level of intelligence [emphasis added]:
The statistical construct known as IQ can reliably estimate general mental ability, or intelligence. The average IQ of immigrants in the United States is substantially lower than that of the white native population, and the difference is likely to persist over several generations. The consequences are a lack of socioeconomic assimilation among low-IQ immigrant groups, more underclass behavior, less social trust, and an increase in the proportion of unskilled workers in the American labor market. Selecting high-IQ immigrants would ameliorate these problems in the U.S., while at the same time benefiting smart potential immigrants who lack educational access in their home countries.
His dissertation, however, was not the first time Richwine promoted these offensive claims. In July 2008, while Richwine was a research fellow at the American Enterprise Institute, he said in a panel discussion of the book The New Case Against Immigration, broadcast on C-SPAN, that “races differ in all sorts of ways, and probably the most important way is in IQ”:
The argument that immigrants themselves are no different from the ones that came 100 years ago I think is, is quite wrong, and I think that the major difference here is ethnicity — or race, if you will. I think that race is important for two main reasons. One is that human beings as a species are a naturally tribal group of people. We have inside, outside, groups. We have families, for one example, where, you know, family comes first in virtually every society. And we tend to be very attuned to even small, trivial differences between groups. I don’t mean to suggest I think this is a good thing, I wish we could be more universalist, but the reality is that we’re not going to be that way, and we shouldn’t be basing policy on that either.
The second reason I think race is important is that there are real differences between groups, not just trivial ones that we happen to notice more than we should. Races differ in all sorts of ways, and probably the most important way is in IQ. Decades of psychometric testing has indicated that at least in America, you have Jews with the highest average IQ, usually followed by East Asians, and then you have non-Jewish whites, Hispanics, and then blacks. These are real differences. They’re not going to go away tomorrow, and for that reason, we have to address them in our immigration discussions and our debates.
