I've never liked measuring intelligence by IQ. IQ may somewhat correlate with intelligence, but it does not describe it in any way. Especially given the kinds of questions used in IQ tests. For example, the 1st question in this test doesn't have the "right" answer: it all depends on what kind of oddity you are focusing on. I would pick the shark, for example, because it is the only ultimate predator from the list - yes, I know, whale is mammal and the other 4 are fishes, but that's just a matter of classification.
According to various tests, my IQ is around 138, but I have to respond in a way I assume they expect me to respond, instead of honestly, and I am VEEEEEERY FAR from the top 1% in terms of intelligence, trust me. Compared to Kasparov, I am a dumb beast!
Too much similar math calculations for an IQ test. The Aristotle and Haydn question looking like a child's play. The test leaves the impression of unassorted things thrown in a heap. No wonder I never do them.
