The academic and policy worlds have been roiled by last week’s announcement that a Heritage Foundation study on the cost of immigration reform was co-authored by Jason Richwine, who wrote a dissertation on the purported low IQ of immigrants. It beyond belief that, in the year 2013, there are still some that want to posit that there is a genetic basis for race. Even more surprisingly, these arguments come endorsed with a seal of approval by some of the nation’s top universities, like Harvard in this case. As an alumnus of the Kennedy School and a scholar of race and Hispanic identity, I feel obliged to provide a response.

Having spent last week with some of the world’s premier scholars of race at a workshop on “Reconsidering Race” at Texas A&M University, in which we examined the interface of social science and genetics/genomics and health, I am stunned by the lack of rigor and intellectual depth evinced by Richwine’s dissertation. The work makes extremely simplistic assumptions about “race,” immigration, and the link between IQ and genetics. Even a neophyte in matters of genetics/genomics can see the gaping holes in Richwine’s logic. One would have expected his advisors, Professors George Borjas, Richard Zeckhauser, and Christopher Jencks to have been more cognizant of the complex nature of terms such as “race”, “Hispanic,” and “white,” as well as their tenuous links to genetics (assuming they actually read the dissertation). Richwine claimed in his Harvard dissertation that “the material environment and genes probably make the greatest contributions to IQ differences” (p. 4) and that “today’s immigrants are not as intelligent on average as white natives” (p. 134).

There are three basic points that have to be made to remind these scholars that such shoddy work should not easily pass at the doctoral level– or any level for that matter. One is the basic idea that “Hispanics” can be of any race (a concept that Richwine references in passing in his dissertation), so that it is not possible to simply oppose “Hispanic” and “white” as if they were mutually exclusive categories (a dichotomy that is crucial to his argument). In fact, Pope Francis is Hispanic; so is Rigoberta Menchu. The term is a politically- and socially-constructed category that has been shaped through historical ties between the US, Latin America, and the Iberian peninsula. There is nothing inherent, natural, or ‘genetic’ in the category of “Hispanic.” There are many people of European ancestry in Latin America, but there are also many of Amerindian origins, African descent, and a vast majority whose origins are a mix of ethnicities, including East Asian, Jewish, Arab, and practically every other group in the world (I myself, for example, am of Aymara, Spanish, German, Italian, and Portuguese origin).

The primitive binary taxonomy of “black vs. white” (emanating from the US one-drop rule) that has somehow become transformed into a spurious “white vs. non-white” Manichean logic is untenable. Not only has racial admixture always been the case (since, as work by Nell Irvin Painter reminds us, there were many ‘white races’ — not just one– at previous historical times), but ‘racial’ mixing has become even more prevalent even in the US in the last five decades as a result of the rapid rise of non-European migration. Even for those who consider “Hispanic” a race, the understanding of this term is cultural and historical, not genetic (for example, in the ideas of the eminent Mexican philosopher Jose Vasconcelos). Race is not a dichotomous variable. The Latin American experience shows us this, and the US would do well to heed that lesson to break down its dualistic racial paradigm.

The second point to be made is that the genetics and genomics revolution of the last two decades or so does have implications for what we understand as ‘race,’ but not in the way that people like Richwine want to argue. Our workshop examined the idea of ‘race’ in light of recent genetics and genomic research in order to see whether it has consequences for our conceptualization of ‘racial’ identities and categories, and also for policies related to health disparities. These are complex and as of yet unresolved questions, but they certainly do not buttress the idea that there are such things as natural entities called ‘’races’’ and that they are rooted in genetic grounds. Recent research shows that humans share about 97% of the same genetic material with orangutans (an animal beloved by visitors to this blog). It also tells us that orangutans are more genetically diverse among themselves than are humans. In other words, people are more alike, across regional populations, than we are different.

And even within the small areas of difference, no evidence exists that such differences make for strictly separate human categories that are essentially discrete. It may be true that some populations share some genetic markers among themselves more than with others, but these differences are minimal. As epidemiologist Jay Kaufman of McGill has argued, the more we learn about the human genome, the closer we are to individuated genetic understanding, not to the construction of broad, essentially-unchangeable human groups. Richwine’s error is to think that IQ is a stable phenotype that reflects universal intelligence. Yes, we should take the genomics revolution as a challenge to simple social-constructivist views of race, but we cannot make the error of thinking that it validates a reification of the complex sociopolitical categories that we call ‘races.’

The last point is that the rudimentary statistical analysis of the kind that Richwine carried out ignores the important interface between social realities and genetics. Besides the problems noted above, we can underscore that even IQ test results are culturally-shaped, and not some measure of a primordial, biological mental ability. Rather, they reflect the intertwining of some aspects of mental capacity with education, life experiences, socioeconomic status, and other contingent contexts. They are not measures of pure intelligence (a dubious concept as well). What we ought to be advocating is not some sort of eugenics-based retrograde Nativist policy that reminds us of the 19th century, but improved educational access for all, and a fair, uniform immigration policy that minimizes discrimination, not enhances it.

It is both morally and intellectually disingenuous to propose what Borjas et al. have been advocating for years now. To claim to favor more immigration of those with “higher IQ’s” or more human capital flies in the face of the fact that low-human capital immigrants contribute profoundly to US economic growth due to their low wages in key industries such as construction, agriculture, and also the service sector. In manufacturing, Hispanics are underpaid relative to their economic value, as sociologist Arthur Sakamoto has shown. Ethically, it is unacceptable for a modern liberal-democratic state to promote high-IQ selectivity in immigration, for this policy advocates unequal treatment rather than uniform standards for all (in this light, Canadian immigration policy, which makes distinctions based on human capital, may be suspect as well, owing to the brain drain that it induces in poorer nations).

As educators, we have a special responsibility to provide non-superficial answers to complex questions. The idea of race is a fraught one. As the Kennedy School is my alma mater, I must say that it is time that policy questions not be treated as merely quantitative or mechanical issues. Public policy schools must also provide coursework that deepens analyses, no thins them down. “Race” is a concept that involves normative, political, historical, cultural, economic, and social forces in a complex interplay. It cannot be bandied about willy-nilly with no sensitivity to them. This idea applies to all racial categories, but it is perhaps most salient for the term “Hispanic,” owing to the rich diversity of ethnic origins that have gone into its making over a long historical period. It is befuddling that no one on Richwine’s committee seems to have been aware of this (in particular Jencks, who has written on these issues in the past).

It is time for antediluvian academics to step aside and give more space to the new generations of scholars that are able to engage in a critique of the all-too-dominant idea that race is merely a social construct but without falling into an antiquated racial essentialism. It is time for a real national dialogue on race that will start new conversations. Our classrooms are a good place to begin these discussions.
