It sounds like David is asking an appropriate question about what psychologists call the "naming fallacy." Here's what Julian Stanley and Kenneth Hopkins had to say about the matter in their authoritative book on educational testing:
Hopkins, Kenneth D. & Stanley, Julian C. (1981). Educational and Psychological Measurement and Evaluation. Englewood Cliffs, NJ: Prentice Hall.
"Many parents are unaware that intelligence tests tend to measure primarily scholastic aptitude and that many other cognitive abilities that can be legitimately considered to reflect intelligence and special abilities are untapped." (page 363)
In this, Stanley and Hopkins agree with Lewis Terman, the author of the Stanford-Binet scales, who by 1937 knew better than to claim that his tests tapped all aspects of intelligent human behavior.
Discussing the relationship between IQ and scholastic achievement, Stanley and Hopkins make a very important point:
"Most authorities feel that current intelligence tests are more aptly described as 'scholastic aptitude' tests because they are so highly related to academic performance, although current use suggests that the term INTELLIGENCE TEST is going to be with us for some time." (He got that right.) This reservation is based NOT on the opinion that intelligence tests do not reflect intelligence but on the belief that there are other kinds of intelligence that are not reflected in current tests; the term INTELLIGENCE is too inclusive." (page 364, emphasis in original)
It's really time to talk here about VALIDATION of IQ tests, "scholastic aptitude" tests, and other mental tests. It doesn't do to simply treat a test battery as a magical incantation that produces a unitless number with no agreed meaning.
