SFRICANGLOBE – Scientific racism has no place in 21st-century academia. Yet somehow, in 2009, Jason Richwine was able to successfully defend a dissertation at Harvard University in which he wrote that Hispanic immigrants have a substantially lower IQ than the White native-born population and that, because of the hereditary nature of IQ, this fact should be taken into consideration when designing immigration policy.
This work is problematic because it is part of a tradition of scientific racism, and because it is based on discredited ideas of intelligence testing and the relationship between racialised categories and genetic makeup.
The US has an ugly history of intelligence testing and immigration policy, and we would do well to avoid repeating that history. In the 19th century, European scientists such as Paul Broca compared the skulls of Africans to those of Whites to prove what they thought they already knew – that the White race was intellectually superior to all others.
The late Stephen Jay Gould has reviewed these studies and shed light on their deep flaws. Eventually, the science of craniometry lost its appeal and scientists began to try to measure intelligence directly through intelligence testing.
One of the first American psychologists to use intelligence testing was H H Goddard, who adapted a version of the test developed by French psychologist Alfred Binet. Goddard believed that intelligence was measurable and that it was heritable. He took Binet’s test to Ellis Island, where he administered it to European immigrants. Goddard found that many arriving immigrants received a low score. Instead of questioning the conditions under which he performed the exam – that is, on recently arrived migrants who barely spoke English and had never before seen a test – he concluded that immigrants were of low intelligence and that immigration must be curtailed.
Richwine’s methods are a bit more nuanced than those of Goddard and Broca, but just barely. Richwine makes a connection between the genetic makeup of Hispanics and their IQ. However, there is no genetic basis for racial differences. And “Hispanic” is an ethnic category including people of every racialised category possible.
In the US, a Hispanic is a person with roots in Latin America. Their ancestry could include people from any continent. The claim that Hispanics share a genetic makeup that could differentiate them from White Americans is simply ludicrous.
Flaws in IQ-Testing
Intelligence testing is also deeply flawed. Stephen Jay Gould points out that the primary error in intelligence-testing is that of reification – making intelligence into something by measuring it. It is common knowledge that some people know more facts and trivia than others, that some are quicker-witted than others, that some can calculate sums in their heads faster than others, and that some are more eloquent in speech and writing than others.
Intelligence tests attempt to take this wide range of abilities and to measure them. The score on these tests is named an “intelligence quotient”, or IQ. Gould contends that these tests are flawed and do not meet their stated goal of actually measuring intelligence.
To the extent that it is true that Hispanic immigrants score lower on these tests than White Americans, this is a result of unequal educational opportunities, not genetics. Diego von Vacano, a graduate of the Harvard’s Kennedy School, points out that:
“the rudimentary statistical analysis of the kind that Richwine carried out ignores the important interface between social realities and genetics… [IQ scores] reflect the intertwining of some aspects of mental capacity with education, life experiences, socioeconomic status, and other contingent contexts.”
Despite the fact that this perspective is widely accepted among scholars, Richwine chose to rely on the scientific racism tradition of his predecessors, and attributed the differences to genetics. This argument harkens back to the eugenics movement of the early 20th century, during which time about 60,000 people were forcibly sterilised in the US on the basis of their purported intellectual unfitness.
Despite this unfortunate history, ideas of innate inferiority and superiority are still advocated by a few, marginal pseudo-scientists. The hereditarian theory of intelligence, for example, continues to be perpetuated through the work of Richard Herrnstein and Charles Murray, authors of The Bell Curve
In 2004, Frank Miele, senior editor of Skeptic, and Vincent Sarich, professor emeritus of anthropology at Berkeley, argued in their book Race: The Reality of Human Differences
Similar to their predecessors, these writers find that their own group – Europeans – is intellectually superior to others. Both of these pseudoscientific books have been heavily critiqued by specialists.
Esteemed race scholar Jonathan Marks, for example, signals the ludicrity of Miele and Sarich’s finding that the average IQ of indigenous Africans is about 70, by pointing out that most native Africans probably speak more languages than Sarich and Miele combined and argues that their book is “scientifically idiosyncratic and politically reactionary”.
As an academic, I find it appalling that, in 2009, three professors at Harvard University were willing to sign off on a dissertation in this academic tradition. There are two central problems with Richwine’s work that should not pass muster in any dissertation committee: first, the argument that IQ scores are an indication of intelligence; and second, the idea that IQ is a genetic trait. Both ideas have been discredited and both are linked to an unfortunate history of scientific racism.
