The bell curve focused on a meaningless trait

Among our cultural and intellectual leaders, the hot topic is an exquisitely promoted book by Richard J. Hernnstein and Charles Murray, called The Bell Curve.

The topic is so hot that it has garnered scores of magazine covers and talk show appearances. The Bell Curve even inspired a fervent protest last week when the surviving author spoke in Denver.

Familiar to all students of statistics, a bell curve displays the distribution of some trait among a population. There are lots of folks in the middle, and as you go left or right from the center line, the population diminishes.

All sorts of mensurable human qualities -- height, weight, American household income before the Reagan presidency -- follow this bell curve.

Among those qualities is intelligence, or if not precisely intelligence, at least the ability to perform well on IQ tests.

The median IQ score for Asian-Americans is somewhat higher than that for white Americans, and the median score for those Americans who identify themselves as black on forms is about 15 points lower than that for whites.

And so what?

Statistical groupings don't tell us anything about individuals in any population, and besides, what's the point of fretting about intelligence? It's not as though American society encourages or cherishes that trait.

For instance, the current cultural icon is a character named Forrest Gump -- an idiot. Before that, Beavis and Butthead were the rage, and if their combined IQ extends into double digits, then we need some new tests. There was the movie Regarding Henry, wherein virtue results from the loss of frontal lobe functions. In Superman sagas, the bad guy is usually Lex Luthor, who boasts a monstrous IQ.

That's Hollywood, of course. But Hollywood panders to a mass market, that is, the same general public which votes.

One way to get ahead in a campaign is to be a plain ol' country boy while your opponent personifies all that is anti-American because he's a double-domed Ivy League intellectual. The fear of being labeled as a member of this despised minority was so potent that George Bush, a Yale graduate, felt compelled to surround himself with horseshoes, pork rinds and Oak Ridge Boys tapes.

Another useful tactic: Take some rather complex issue like international trade, announce a moronic solution that would shame even a newspaper columnist, and proclaim, in a peckerwood accent never associated with scholarship, It's just that simple, folks.

Observe the groves of academe, where you might naively think that intelligence matters. See bright children gain the hatred of their classmates for breaking the curve or acting white. Try to parse the prose produced by school administrators or officers of the teachers' unions. Look elsewhere for signs of intelligent life.

Further, our economy relies on stupidity: The tobacco industry. Our state lottery. The emerging prison-industrial complex. The general run of network television. A publishing industry that makes Fabio and Millie into best-selling authors.

Now I firmly support my right, and yours, to be stupid. The authors of The Bell Curve may or may not have meant well, but the real problem is that their topic was irrelevant. If they had wanted to study what it takes to succeed in this country, they would have examined one of these curves.

The Ball Curve: Inspect the statistical relationship between athletic skill and the attainment of many of the good things that America has to offer -- easy classes, adulation, assignations with comely cheerleaders, the need for financial advisors at age 21, publicly-financed facilities for the display of one's sporting talents, celebrity endorsement contracts and an outpouring of public interest and sympathy when on trial for heinous crimes.

The Bill Curve: An inquiry into the number of Treasury Bills controlled by the trust funds established by one's grandparents, and the subject's later success in life.

The Boll Curve: Nothing symbolizes the South quite so much as the cotton boll, and this study would examine the relationship between a candidate's perceived Southern qualities and his consequent political success.

Positive attributes include the number of guns owned by the subject, his willingness to deploy them on doves and trespassers and his televised presence at stock-car races and military festivals.

The Bull Curve: Although corporate America has been down-sizing, it still plays an important in the national culture. While other studies have examined factors like dedication and intelligence, the Bull Curve will focus on other traits.

We have developed new ways to measure such vital skills as bull-slinging, brown-nosing and apple-polishing, and we can group them into an Obeisance Factor. These scores will be applied to standard random distributions of the corporate work force, and then compared to promotion and compensation rates.

It is believed that the resulting Bull Curve will show no correlation between IQ and success, and a strong correlation between Obeisance Factor and success.
