> SAT being an IQ is a stretch. SAT is a scholastic amplitude, a far more narrowly defined construct. SAT is an IQ test[1]. It was always an IQ test. There might be better (i.e. more g-loaded) tests out there, but the SAT still definitely works. > You might have meant to say that SAT is correlated with IQ. While true, that is by design and is scientifically uninteresting on its own. The SAT is correlated with g, which makes it an IQ test. You claimed that IQ doesn't correlate with anything other than performance on IQ tests. That is clearly incorrect with regard to academic performance. That you find this correlation 'uninteresting'is frankly beside the point. > If your model includes scholastic amplitude but you measure it in IQ, you will not only have a less accurate model, but you will also make gathering data way more expensive and difficult. There's not one 'IQ' test. Anything that correlates strongly with g is an IQ test. Yes, it also tests knowledge, but the ability to learn and recall facts is a heavily g-loaded activity.
