I think anyone with an IQ over 80 would agree that's more of a red herring than a test of actual intelligence, so, if we can dispense with absurd fringe examples of the abuse of the concept of "IQ" maybe we can get down to the nuts of what companies are looking for, what programmers are trying to provide, and put a stop to this dramatic yarn about "how hard it is to find good help" once and for all.
The example was for small children and speaks more to the fact that IQ tests are in practice more discriminatory than they are designed to be. That's all.
If you can come up with a way to test for general intelligence without inadvertently biasing your tool in favor of a specific ethnicity, social class, or gender we're all ears.
Curiously, American minorities score more poorly on culture-neutral tests like Raven's Matrices. They do better on culturally biased tests because they can pick up mainstream culture knowledge from TV and movies.
