THE EFFECT OF URBAN FLIGHT ON IQ DISTRIBUTION

From La Griffe du Lion:

Baltimore is typical of many Midwestern and Northern cities, whose demographics were forever changed by the great black migration of the twentieth century. Not unexpectedly we found a cognitive discontinuity at the city line. Surprising, however, was its magnitude. Whereas suburban mean IQs (86 for blacks, 99 for whites) conform more or less to national norms, city IQs are dreadfully low. With a mean IQ of 76, inner-city blacks fall about 0.6 SD below the African American average nationally. More than a third have death-penalty immunity on grounds of mental retardation. The inner-city white mean of 86 is nearly a full standard deviation below the national white average. By this measure, whites fared worse than blacks. Both groups are seriously deficient in human capital. Neither is very employable. To compound matters, we almost certainly have overstated urban IQs. City residents constitute a low-IQ group extracted from a more cognitively representative population. Their kids, whose test scores we analyzed, should have regressed toward their racial means, i.e., toward higher IQs. That is, inner city kids are smarter than their parents. Accordingly, our estimates of inner-city IQs are best regarded as upper bounds to adult values.

IQ hardens early in life, locking in the urban deficit. With few prospects for improvement, cities must look elsewhere for amelioration. While we all are aware of the advantages that accrue to the brightest among us, we also know that other qualities carry with them inestimable benefits. Traits like honesty, reliability, perseverance and self-discipline, when cultivated contribute to employability and to a more productive life in general. Indeed, for low-skilled jobs these latter qualities are more important than intellect. Unfortunately, casual observation finds such virtues also wanting.

Finally, we note that a problem cannot be solved until it is defined. This we have done. But where we see cognitive inadequacy, some will find only abject, hopeless misery. As for our efforts, we can be certain of only one thing — vilification. It could drive a man to pseudonymity
