What was the point of repeating yourself? You didn't specify what those measurable things were. My point is, the term "IQ" should not be used if the test is unable to measure what its name implies. That's about it. The cultural bias in IQ tests has been widely documented. However, I must admit the usefulness of these tests by the U.S. Army and Marine Corps in decreasing fatality rates. It might be better to rename these tests though.
