>predictive power isn’t the same as conceptual completeness.
It matters a whole lot more than vague "conceptual completeness".
>PCA finds patterns, not truths
It pretty much does find "truths", how else would you describe real associations (fake maybe?).
>Intelligence is adaptive, contextual, and expressed in diverse ways, IQ tests sample a narrow slice.
You still haven't defined your nebulous version of "intelligence" or it's "essence".
>Culture-free tests still show group gaps not because they remove all bias, but because inequality runs deeper than language.
I never said they remove all bias, but they (just like the rest of IQ tests) don't really have bias (due to DIF and Factorial invariance measures).
