Thanks for that very nice recap of intelligence testing. It must be frustrating to have to continuously defend your research area as something real.
I’d like to challenge you on the claim that controlling for social class (or other factors) allows for concluding that a true IQ-mortality connection exists. We could claim this only if we had perfectly accurate measures of socio-economic status, and our measures of SES are quite crude. If SES affects both IQ and mortality, and we measure SES imperfectly and then partial out that imperfect bit from IQ and mortality, then some of the remaining IQ-mortality correlation could still be due to the unmeasured remainder of SES.
How clever is it to dismiss IQ tests?
