Could you rephrase that in English, please? (I feel like such a bastard for using that phrase, but I honestly can't tell what you were trying to say.)the .303 bookworm wrote:IQ measures against average intelligence,
it cant tell if youre exceptional,
A completely apathetic genius would get widely differing scores on different sections of a modern IQ test. The WISC-III test, for example, has sections on "information" and "vocabulary", on which your hypothetical genius would do poorly, and sections which require no general information beyond what any child has, such as transcribing digit codes and various visual sections.Also it measures general knowledge, a genius who doesnt care about the world could have a low I.Q by some tests.
The vast disparities in scores between different parts of the test would certainly raise eyebrows---and I find the apathetic genius scenario to be so unlikely that this discussion is moot anyway.
IQ certainly measures something, since it is correlated with employment, lower divorce rates, and a number of other good things. Additionally, general intelligence (which many IQ tests attempt to measure) is correlated with biological factors like gray and white matter volume, and overall brain volume. These factors correlate especially strongly with working memory, and less strongly with mental processing speed.
