The thought police are at it again. The latest confrontation is at Virginia Tech University at Blacksburg where the usual suspects — a coalition of black activists and white leftists — have called upon the university president to withdraw an invitation to Charles Murray, where he is scheduled to speak on March 25 at Tech’s business school. Murray will give an address drawn from his latest book, Coming Apart, which explains the increasing economic and cultural polarization that has taken place in America because of structural changes in our information-based, post-industrial economy.

Like much of Murray’s interest over the past three decades, Coming Apart focuses on the alarming growth of a downwardly mobile, and ever-more disoriented white underclass at the same time that a highly educated white over-class has pulled away and isolated itself in upscale, affluent communities.

These latter groups, Murray argues, have a vastly disproportionate influence on how public policy is conducted in America, yet they lack an understanding of the needs and traditions of less affluent and less well educated people. The protesters, however, seemed unconcerned with what Murray intends to say at Virginia Tech. Their sole objection is to the very appearance of Charles Murray, the co-author of the rarely-read but much vilified book, The Bell Curve, which was published more than 20 years ago.

<How Our Campuses Came to Reject Free Speech>

Together with his co-author, the late Richard Herrnstein — a distinguished Harvard psychologist — Murray documented in The Bell Curve the increasing returns in the job market to those with high abstract reasoning ability as indicated by high IQ test scores. The book’s primary concern was with IQ differences among socio-economic groups — a topic Herrnstein had written about many years earlier. But two chapters dealt with the data on IQ and race. It was this material that produced an explosion in commentary by reviewers, much of it hostile, uninformed, and irrational.

The Bell Curve pointed out that decades of testing had shown a persistent IQ gradient around the world with Ashkenazic Jews at the top, followed by northern Asians, whites, Latinos, African Americans, and at the very bottom black Africans, the latter a full standard deviation (15 IQ points) behind their descendants in America. After surveying much of the relevant technical literature on the topic, Murray and Herrnstein concluded with what, under more rational circumstances, would surely have been considered a very moderate, reserved, even anodyne statement about the likely causes of these differences:

If the reader is now convinced that either the genetic or the environmental explanation [for racial differences in IQ scores] has won out to the exclusion of the other, we have not done a sufficiently good job of presenting one side or the other. It seems highly likely to us that both genes and the environment have something to do with racial differences [in IQ scores]. What might the mix be? We are resolutely agnostic on that issue; as far as we can determine, the evidence does not yet justify an estimate. (p. 311)

Moderate and circumspect though such a statement may seem, it brought the roof down on the two Bell Curve authors, with Murray having to face the avalanche of criticism alone since his co-author died unexpectedly just as the book was going to press. The style, substance and quality of much of the criticism are well captured by the title of one of the reviews in The New Republic: “Neo-Nazi!”

The Bell Curve had clearly breached a powerful taboo, one that calls for explaining racial, ethnic, and socio-economic differences in IQ scores solely in terms of non-genetic, non-heriditarian factors. To a large segment of the American intellectual and media elite a genes-plus-environment explanation was simply unacceptable and identified with the demented minds of Nazis and Klansmen. Even if Murray himself were not a Nazi or Klansman, he was, many commentators seemed to believe, at the very least a fellow traveler and his book gave aid and comfort to the most despised enemies of the human race.

An Open Letter from a Suddenly Disinvited Speaker

For many elements of the campus Left, this is still where Murray stands, and his appearance on a university campus, even to discuss matters unrelated to race, must never be tolerated. This is true despite Murray’s impeccable scholarship, his great personal integrity, his concern in recent years for developments among whites rather than non-whites (Coming Apart is subtitled “The State of White America 1960-2010”), and the ever-increasing acceptance by knowledgeable researchers of The Bell Curve’s basic genes-plus-environment explanation for a host of human differences.

Even in its own time The Bell Curve was hardly an outlier in terms of what it said about racial differences in IQ scores and their likely origin. A poll of professional psychologists, sociologists, and behavioral geneticists conducted years before publication of the Murray/Herrnstein book found the proportion of those favoring a genes-plus-environment explanation for the persistent black/white IQ-gap exceeding those favoring an environment-only explanation by a factor of 3-1.

Only 17 percent of the respondents were in the environment-only camp, versus 53 percent who believed that both genes and environment were responsible for the observed IQ differences. Of the remainder, only 1 percent adopted a genes-only explanation while the rest said the data were insufficient to make a sound judgment. See Mark Snyderman and Stanley Rothman, The IQ Controversy, the Media, and Public Policy. In recent years, with the exponential growth of interest in behavioral genetics, this 3-1 ratio may well have increased.

Among the campus Left, Murray continues to be vilified as a “fascist,” “Nazi,” “Social Darwinist” and the like, though he is simply a rigorously honest scholar — the New Republic editor Andrew Sullivan once described him as “honest to a fault” — with an exceptionally humane, classical liberal approach to most social problems. At Virginia Tech, a group calling itself the Coalition for Justice fell into this standard pattern of Murray vilification. In a public statement, the group objected to having Murray speak on campus saying that his was a voice of prejudice and hate that should not be given a Virginia Tech forum.

“At the time when rising racism, misogyny and anti-intellectualism have moved to the forefront of our national consciousness,” the group said in its statement, “there is no better place than a college campus from which to focus our efforts against the voices of prejudice and hate. … Mr. Murray’s social Darwinist take on intelligence, ability and morality — and his assertion of the inherent racial and gender inferiority of non-whites and women — do nothing but promote a white supremacist agenda, cast in the guise of ‘scientific discourse’.” The group wanted the business dean to rescind Murray’s invitation.

(How the “misogyny” theme got in there is anybody’s guess, since Murray has never written anything that can be construed — or even misconstrued — as critical of women whether in The Bell Curve or, to this writer’s knowledge, anywhere else. In Coming Apart it is the lazy, irresponsible, uninvolved white fathers in the Philadelphia neighborhood of Fishtown who clearly stoke his ire).

The anti-Murray onslaught was joined by both the local Virginia Tech chapter of the NAACP and several faculty members of the Africana Studies Program. The latter group issued a statement that while not calling for revocation of Murray’s invitation said that Murray was “engaged in a mission to use discredited pseudoscience to perpetuate the subordination of people of African descent, Latino/as, Native American Indians, the poor, women and the disabled.” His ideas were seen as perpetuating a kind of narrative that would “visit violence upon marginalized populations — recalling the history of forced sterilization, unjust institutionalization and incarceration, and denial of basic human rights.”

The president of Virginia Tech, Tim Sands, also got into the act of issuing public statements with “An Open Letter to the Virginia Tech Community” that can best be described as combining elements of “the good, the bad, and the ugly.” On the good side, Sands refused to rescind the invitation to Murray while reaffirming the values of academic freedom and open debate at Virginia Tech.

On the bad and ugly side, the Open Letter erroneously claimed that Murray’s views on race and IQ had long been discredited, and that Murray’s scholarship promoted ideas that were not merely false but dangerous, since they gave aid and comfort to fascists and other evildoers. Murray, said the Open Letter, “is well known for his controversial and largely discredited work linking measures of intelligence to heredity, and specifically to race and ethnicity — a flawed socioeconomic theory that has been used by some to justify fascism, racism and eugenics.”

Murray could not take all this sitting down, and in the form of his own “Open Letter to the Virginia Tech Community,” he responded to president Sands’ remarks. While giving a “Bravo” to Sands’ defense of intellectual freedom, Murray accused Sands of being “unfamiliar either with the actual content of The Bell Curve …. Or, with the state of knowledge in psychometrics.” Anyone who has carefully read The Bell Curve and kept up with developments in psychometrics and related fields of intelligence research would hardly dispute Murray’s assessment. Murray proceeded to cite some of the findings of the American Psychological Association’s Task Force on intelligence, a group of leading specialists in psychometric testing, which published its findings in the February 1996 issue of the American Psychologist.

On the issue of black/white differences in IQ scores, the hereditability of intelligence, and the predictive validity of IQ for the differing black and white populations, the Task Force came to conclusions virtually identical to those of The Bell Curve authors (the Task Force’s report can be obtained online by googling “Intelligence: Knowns and Unknowns – CiteSeerX”).

<Princeton Takes a Stand on Free Speech>

Continuing his indictment of Sands’ statement, Murray wrote that it was particularly exasperating to have the president of a distinguished university accuse the authors of The Bell Curve of presenting material that has been scientifically discredited. On the contrary, Murray says, “our presentations of the meaning and role of IQ [in The Bell Curve] have been … steadily reinforced by subsequent research in the social sciences, not to mention developments in neuroscience and genetics.” Murray was most upset, however, by Sands’ accusation that he was promulgating a theory used in the past to justify fascism and racism. At this point President Sands, Murray wrote, “went beyond the kind of statement that merely reflects his unfamiliarity with The Bell Curve and/or psychometrics. He engaged in intellectual McCarthyism.”

Such is the state of much of academia where a combination of left-wing political correctness, the cowardice of university presidents, and the fear of being called a racist determines the order of the day. In saner times, a scholar of Murray’s stature would be honored wherever went and he would probably hold an endowed chair at an institution like Harvard or Stanford. Today, he never knows if he will be allowed to show up even at an institution that has invited him to speak.
