I didn't understand this either. What would it mean for a human measurement to be transitive or monotonic? Maybe there is a good definition for these but it's not obvious to me.

I think he's using a measure-theoretic meaning of a measure. Suppose I asked you what the difference in intelligence is between person A and person B. The problems with that would start pretty rapidly.

So by "transitive" he means "countably additive"? Monotonic and transitive aren't in the definition of measure and it's still not obvious what those definitions mean in terms of measuring people.

Another comment mentioned something called 'progressive matrices', these tests are not based on any crystalized (studyable) knowledge. You could practice solving the sort of visiospatial puzzles that they pose but then you'd ruin your results. People who use these tests are expected to have not had much/any experience with solving the types of puzzles it presents.

"You could practice solving the sort of visiospatial puzzles that they pose but then you'd ruin your results." You are contradicting yourself. First you claim it is not based on studyable knowledge, then you claim studying for the tests ruins the results. Some people solve similar puzzles during their life and get practice for the tests, others do not.

Fair enough. They are trainable to a point from what I understand. I was thinking along the lines of rote memorization.

The main thing people are hoping to measure as I understand it is the quickness with which one learns to recognize patterns and organize concepts. Measuring someone's quickness when they aren't starting from zero will obviously have a bias. Luckily it's easy for field researchers to find people who aren't solving symmetry puzzles in their spare time, or taking courses about abstract algebra.
