No, I'm a Gusev person (like, reading within-families papers grade Gusevian), and I'm deeply skeptical of psychometrics. I was radicalized by Shalizi. But lots of tools that don't produce coherent metrics or have valid axiomatic derivations are nonetheless useful in clinical settings, and by denying that you concede to your opponents --- the "race scientists" --- the idea that you're dismissive of science that serious practitioners still deem valid. Don't surrender that card so easily.

(btw: if you're not up with Sasha Gusev yet, run don't walk --- midwit race scientists are constantly bouncing off him and it drives people crazy. curtis yarvin threatened to have imprisoned. i love him so much.)
