Using Intelligence to Assess Intelligence

“Using my intelligence I take note of the fact that no effort however expensive has ever enabled most blacks to perform and behave as well as most whites.”
(John Engelman, as he commented in response to me in our ‘debate’ on a book review of On the Run: Fugitive Life in an American City by Alice Goffman.)

Why don’t you use your intelligence to take note of the fact that no effort however expensive or cheap has ever even been attempted to objectively test whether it is possible to enable most blacks to perform and behave as well as most whites?

The amount of public funding, public support, and political will required to undo the history of racism, sadly, would be more than the American population and the U.S. government is at present capable of. We don’t know if we could accomplish it because we don’t even know if we want to accomplish it. We don’t know because it is an untested hypothetical, but maybe we should test it.

To be honest, we can’t speak of most blacks and most whites about most things. There is so little data about most blacks and most whites. What little data we have generally isn’t of the highest quality. There are too many biases in the data and too few effective methods in collecting the data for controlling for confounding factors. There is way more we don’t know than we do know. To be intellectually honest we have to be intellectually humble.

However, we shouldn’t dismiss what we do know, no matter how imperfect. We do know that environment has influence on IQ. Yet we have found no genetic racial explanation at all.

Stephen Jay Gould, in The Mismeasure of Man (Revised & Expanded), he has some new comments directed at the authors of The Bell Curve, which speak directly to your arguments:

“Herrnstein and Murray violate fairness by converting a complex case that can only yield agnosticism into a biased brief for permanent and heritable difference. They impose this spin by turning every straw on their side into an oak, while mentioning but downplaying the strong circumstantial case for substantial malleability and little average genetic difference (impressive IQ gains for poor black children adopted into affluent and intellectual homes; average IQ increases in some nations since World War II equal to the entire 15-point difference now separating blacks and whites in America; failure to find any cognitive differences between two cohorts of children born out of wedlock to German women, and raised in Germany as Germans, but fathered by black and white American soldiers).”

So, we do know that most blacks under these environmental conditions apparently do as well as most whites under these environmental conditions. We don’t know what would happen if were able to create the exact same environmental conditions for all blacks and whites in the entire United States.

By the way, the IQ gains aren’t measly. They are possibly larger than the entire IQ gap between blacks and whites. As Richard Nisbett, in Intelligence and How to Get It: Why Schools and Cultures Count, explains:

“The difference between the average IQ of the children of the lower third of the socioeconomic status (SES) distribution and the average IQ of the children of the upper third is about 10 points. We know that some of this is due to biological but not genetic factors, including exercise, breast-feeding, and exposure to alcohol or cigarette smoke, as well as hazardous chemicals and pollution. And some of it is due to the disruption in schools of lower-SES children and to the fact that peers are pulling intelligence mostly in a down direction. We also know that socialization in lower-SES homes is not optimal for developing either IQ or school readiness. Moreover, a child born into roughly the bottom sixth of the SES distribution will have an IQ 12 to 18 points higher if raised by parents from roughly the top quarter of the SES distribution.”

None of this should surprise us. Why would we even assume that genetics is a major factor when the vast majority of the evidence points in the opposite direction? In The Bell Curve Wars: Race, Intelligence, and the Future of America, Steven Fraser writes:

“There are a total of seven studies providing direct evidence on the question of a genetic basis for the B/W IQ gap. Six of them are consistent with a zero genetic contribution to the gap (or with very slight African superiority) based just on the raw IQ numbers, and though all of these six suffer from some interpretive difficulties, they mostly boil down to a single objection. If it was very low IQ whites who mated with blacks (or very high IQ blacks who mated with whites), the results could be explained away. (One study, which compared blacks and whites in the same institutional environment, is free from this objection.) The self-selection factor would have had to be implausibly great, however, and would have had to be present under a variety of circumstances, in several very different locales, at several different time periods. The remaining study-the only one that the authors write about at any length-is at least on the face of it consistent with a model assuming a substantial genetic contribution to the B/W gap. But that study has as many interpretive problems as the others, including the two studies which the authors mention only to dismiss. Any reader would surely reach very different conclusions about the likely degree of genetic contribution to the B/W gap by virtue of knowing the facts just presented than by reading the highly selective review presented in The Bell Curve.”

The best evidence we have shows about zero genetic influence. It’s a bit more complicated than this, for the genetic influence is dependent on the environmental influence. David Shenk, from The Genius in All of Us: New Insights into Genetics, Talent, and IQ, quotes from the author of a study:

““The models suggest,” Turkheimer wrote, “that in impoverished families, 60% of the variance in IQ is accounted for by the shared environment, and the contributions of genes is close to zero; in affluent families, the result is almost exactly the reverse.” (Italics mine.) (Turkheimer et al., “Socioeconomic status modifies heritability of IQ in young children,” p. 632.)”

Basically, genetic influence is so minor that it can only be detected when all of the negative environmental factors no longer have much influence. It is the same between Europeans/Euro-Americans and other racial/ethnic groups, beyond just blacks. To return to Nisbett, he speaks about Asians and Jews:

“At any rate that has been true for Asians and Jews. There is no reliable evidence of a genetic difference in intelligence between people of East Asian descent and people of European descent. In fact, there is little difference in intelligence between the two groups as measured by IQ tests. Some evidence indicates that East Asians start school with lower IQs than do white Americans. After a few years of school this difference seems to disappear. But the academic achievement of East Asians—especially in math and the sciences, where effort counts for a lot— is light-years beyond that of European Americans. Americans of East Asian extraction also differ little in IQ from European Americans. In any case, the academic achievement and occupational attainment of Asian Americans exceed by a great amount what they “should” be accomplishing given their IQs. The explanation for the Asian/ Western gap lies in hard work and persistence.

“Jewish culture undoubtedly has similarly beneficial effects. Jewish values emphasize accomplishment in general and intellectual attainment in particular. Differences between Jews and non-Jews in intellectual accomplishment at the highest levels are very great. A genetic explanation for this is not required inasmuch as even greater differences have occurred for Arabs and Chinese versus Europeans in the Middle Ages, for differences between European countries at various points since the Middle Ages (with reversals occurring between Italy and England and with movement from savagery to sagacity in scarcely two centuries in Scotland), and for regional differences in the United States. We are left with an IQ difference of two-thirds to a standard deviation between Jews and non-Jews. At least some of this difference is surely cultural in origin.”

A genetic explanation isn’t even necessary, even if significant genetic evidence could be found. Why be cynical and fatalistic? There is no rational reason to see IQ divides as racially deterministic. From Brainwashed: Challenging the Myth of Black Inferiority, Tom Burrell gave an example of a school that had great success using different methods, i.e., changing the environmental conditions:

“Education experts are keeping an eye on the Afrikan Centered Education Collegium Campus (ACECC) in Kansas City, Missouri . The 40-acre campus, which opened in 2007, serves mostly black pre-kindergarten through 12th grade students . Teachers stress cultural pride and “expected greatness” as students strive for academic excellence. In 2007, all the schools on the campus met the Average Yearly Progress (AYP) standard mandated by the national “No Child Left Behind” Act.

“The schools are the brainchild of educator Audrey Bullard, who worked as a teacher in Liberia for 18 months more than 30 years ago. In 1991, Bullard led a grassroots effort with other educators and parents to transform J.S. Chick Elementary in Kansas City into a school with an African-centered curriculum. The school has consistently scored as one of the top schools in the school district, with 48 percent of its students scoring at the proficient or advanced levels on the Missouri Assessment Program (MAP) fourth -grade math test in 2005 . Comparatively, only 24 percent of black students and 36 percent of white students statewide scored as high that year. Although the approach relies heavily on parental involvement and an innovative curriculum, it offers another important component: students are taught to see themselves as contributors, leaders, potential entrepreneurs, and valuable parts of their communities.”

Most blacks in this school, who were normal kids, did better than most white kids outside of this school. The determining factor was the school the kids attended, not their race.

Such an example doesn’t absolutely prove that this or anything similar could cause “most blacks to perform and behave as well as most whites”. But it sure does offer strong evidence that this probably is the case. We have no reason to assume otherwise.
