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 could attribute it to another variable, if I didn’t have one study that would say "intelligence and rationality are tightly coupled" in front of me, and none saying "rationality is coupled to another random variable".

Anyway what’s important is that there are some people that claim "IQ tests don’t test correctly intelligence because they don’t test X or Y". They can’t use rationality now.

I'm not saying that it's incorrect. I guess I'm just slower to accept a world view just because of a study. I couldn't tell you how many times a conclusion from a study is reversed in the years after.
