IQ tests are robust but only compare a person with their cohort.

Sir Francis Galton tried to remedy that (and any other problems with the test) using Reaction Time Testing. In modern terms(Galton is 19th century), a computer that calculates faster is more advanced than a slower computer. The correlation with IQ tests is weak but IS there.
