Taboo

The audacious Jennifer Senior apparently enjoys professional danger. She's written an article in New York magazine which explores the work of two researchers who live even more dangerously, Henry Harpending, an evolutionary anthropologist at the University of Utah, and Gregory Cochran, an independent scholar. She writes that:

The two shopped around a paper that tried to establish a genetic argument for the fabled intelligence of Jews. It contended that the diseases most commonly found in Ashkenazim-particularly the lysosomal storage diseases, like Tay-Sachs-were likely connected to and, indeed, in some sense responsible for outsize intellectual achievement in Ashkenazi Jews....Most American academics expected the thing to drop like a stone.

Yet to invoke the genome as an explanation for anything more complicated than illness or the most superficial traits (like skin color) is still considered taboo, as Harvard president Larry Summers discovered when he suggested the reason for so few female math and science professors might lurk in scribbles of feminine DNA (rather than, say, the hostile climes of the classroom, the diminished expectations of women's parents, or a curious cultural receptivity to Pamela Anderson's charms).

Though Jews make up a mere 0.25 percent of the world's population and a mere 3 percent of the United States', they account, according to their paper, for 27 percent of all American Nobel Prize winners, 25 percent of all ACM Turing Award winners for computer science, and 50 percent of the globe's chess champions. (What the paper doesn't say is that these numbers seem to be tallied for optimum Jewishness, counting as Jews those who have as few as one Jewish grandparent to claim; it also wrongly assumes these winners are all Ashkenazim. But still.) Cochran and Harpending also cite studies claiming that Ashkenazim have the highest IQ of any ethnic group for which there's reliable data, perhaps as much as a full standard deviation above the general European average, which means, at the far end of the spectrum, that 23 per thousand Ashkenazim have an IQ over 140, as opposed to 4 per thousand Northern Europeans.

Freud and Marx, Einstein and Bohr, Mendelssohn and Mahler. The brothers Gershwin. The brothers Marx. Woody Allen. Bob Dylan. Franz Kafka. Claude L�vi-Strauss. Bobby Fischer. The list of accomplished and brilliant Jews seems endless and begs an explanation.

Harpending and Cochran's study, though, has produced a great deal of consternation and criticism, not because people don't think that Jews really are smarter than the average Caucasian but because there's a very dangerous flip side to the discussion. If intelligence is correlated to ethnicity or race then...are we heading toward another Bell Curve debacle which brought no end of invective and criticism upon the head of author Charles Murray? Here lies ground the prudent academic dare not tread upon, and in order to avoid it all statements of the obvious, for example, that Jews and Asians seem to be disproportionately brilliant must be treated as if they carried HIV.

The problem with saying such things out loud in public is that people's minds immediately fly to another obviously disproportionate giftedness, that of African-American athleticism. So what's wrong with that, you ask? Silly you. You must be from Mars.

As William Buckley is fond of putting it, he who says A must say B. The flip side of the prowess displayed by Jews in the realm of the mind is that it certainly seems that Jews and, to a lesser extent, Asians are athletic underachievers (at least in most of the sports popular in America). But now we've gone and done it, because this observation invites the forbidden question of why African-Americans, taken as a whole, seem to be conversely situated.

Studies like the one Senior writes about are not welcome in the PC world of academe where uncomfortable racial implications of research are best swept quietly into the closet. If Jewish, and Asian, intellectual achievement is largely genetically explained then, the dread question is, does the failure of African Americans to do as well in the classroom as they do on the athletic field also have a genetic explanation? And this question, it is objected, plays right into the hands of racists. To which I, being one who is gifted neither intellectually nor athletically, say phooey.

Genuine racists, those who could and would do harm to people simply because of their race, are an insignificant fraction of the population today, at least among whites, despite what the race hustlers would have us believe. It's time we start addressing uncomfortable facts about ourselves like grown-ups instead of stuffing them in our national anxiety closet when they conflict with what we'd like them to be. We are better served by confronting difficult truths, if indeed truths they be, than by hiding from them. The more thoroughly we understand ourselves the more effectively we can work to make life better for all Americans. We say, let's take our hands from over our mouths, eyes, and ears, and let's do the research. Let the facts fall where they may. We shouldn't fear knowledge.
