Neuroscience Twin study suggests rationality and intelligence share the same genetic roots - the study suggests that being irrational, or making illogical choices, might simply be another way of measuring lower intelligence.

I would question the validity of any concept of "intelligence" for which this is not true

I'm pretty sure this was already established. IQ tests test for "intelligence". They are logic tests. That's all they are. If you are illogical, you do worse and thus have a lower IQ, and therefore, lower intelligence. Idk what other correlation people were expecting. This just reinforces hundreds of years of established theory.

Not true. I don't know what tests you've taken, but there are intelligence tests that do not test logic. The ability to remember digits. The ability to remember words. The ability to look at a diagram, and then draw it from memory. The ability to play the memory game Simon. The time taken to press a button when you see an X, but not press it when you see any other letter.

You just described a bunch of memory games. Memory isn't even remotely the same as intelligence. It's just remembering things. It doesn't mean you are capable of understanding what you are remembering.
