“It is up for debate, but it’s a tautological question. It measures what it says it measures. You can (and IMO, should) define intelligence more broadly than what IQ tests measure, but that would not be the test/results we are discussing.”
Veltz, you are right that it is tautological but the tautology should be expressed as follows: IQ tests measure how well people do on IQ tests.
It is not so much that intelligence is broader that what IQ tests test, it is that it is unclear whether the IQ test has any relationship with intelligence at all. It is also not clear that “general intelligence” even exists (as opposed to specific skills in specific areas).
I think that intelligence is very important, but I wouldn’t trade anything for additional IQ points because IQ points are valueless (and inane).
