IQ is a culturally-biased measure that, on its best day, is useful for comparing different cohorts and, if it's being used for a good purpose, bridging any gaps. It only measures individual intelligence by a very narrow view of intelligence. There are plenty of high IQ dupes and highly effective people who'd flub an IQ test.
