The claim that professionally-administered IQ tests are culturally biased enough to make a real difference is far less true than it was forty years ago. The substantive criticisms have been well aired and taken into account.

But that's secondary to the genetic findings reported.

As I read the article, the findings are of tremendous interest to geneticists, but they should be of little significance to anyone else. Put simply, the researchers say they've found a strong genetic component behind all forms of intelligence. Yet it doesn't come from a handful of genes, as was once thought possible. Instead it comes from a thousand or more teeny-weeny influences arising from many, many genes. And just how these influences may effect the intelligence of any individual (not to mention any population group)is unpredictable, because those influences don't all kick in automatically, uniformly, equally, or on schedule. Like many other genetic components, they are crucially influenced by other factors.

In biological terms this sounds like a significant advance in understanding how humans evolved and how individuals develop. In sociopolitical terms (which are more likely to get Mudcatters hot under the collar), the discovery is meaningless.

You still can't tell how smart, talented, competent, etc., a healthy person of any background is, or is going to be, based on any genetic information whatsoever.

Expect, however, that the findings will be distorted and denounced as racist, or as giving aid and comfort to racists.

If the article is accurately reported, that response would be self-serving and absurd.
