That we cannot measure intelligence reliably after a certain point does not imply that there are not (infinite?) levels of intelligence after it. There are certainly—at least theoretically—levels of fluid intelligence that correspond to IQs of 170, 180, 300..., and it was in this theoretical sense that I raised my question.
Current IQ tests are pretty meaningless past >160, so as long as this works in the 70-160 range, we’re fine.
