Fluid intelligence measures like Ravens have proven valuable for predicting success in mathematics—and little else.
Cite please. This is a completely novel claim to me, one I routinely see problems with (eg. a few days ago reading a SMPY review mentioning a 13-fold gender imbalance in extremely high SAT math scores while tests of fluid intelligence show little or no such asymmetry). I find it very hard to believe that matrix tests predict mathematics success and little else.
If you are trying to express some reasonable position like “IQ tests (which include subtests covering a variety of crystallized materials as well as fluid intelligence measures) will have some incremental predictive validity for various activities or life outcomes over an IQ test (which is just a measure of fluid intelligence)”, then perhaps one could agree. But your current absolutist statements seem to be endorsing some other position...
