Quite so. But again: a score of 145 on the Cattell 3B (for example) is just that - a score - one that places you in the top two percentile. It doesn't mean that 145 is therefore your IQ. Those numbers are meaningless, being dependent on the test. It's only the percentile that signifies.Roger Lancaster wrote: ↑Sun Aug 18, 2019 10:03 amThere's a certain amount of scepticism about IQ tests in general but I'll leave this to one side in what follows. If I understand the basis behind these tests correctly, the typical IQ test - which is designed to measure IQs over the range which most commonly occurs in practice - is such that anyone with an IQ at or above the top of this range should score 100% or very close to 100%. Consequently, the typical IQ test won't differentiate between persons with IQs above this range. To measure IQs much above 145 or thereabouts (Cattell), I think you'll find a separate test is needed with harder questions and/or less time.
