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.

So instead of saying "He's an idiot" you could say "He's irrational" and it would basically indicate the same issue? Good to know.

I don't agree. Intelligence is problem solving ability. Rationality is the ability to think using logic and not emotion. Someone who is intelligent can also be irrational if they are highly emotional and make certain choices based on emotion rather than logic.

Emotions and rational thinking are not inherently at odds; those types of thinking can go hand in hand. The only reason there is a popular idea that rationality is devoid of emotion is because people who aren’t thinking rationally have to have SOME way of coming to their conclusions, and without logic it will naturally fall entirely on emotion.

Rational thinking can and does very frequently intersect with emotion, and assuming otherwise because “irrational people use emotion as a crutch” is itself illogical. All squares are rectangles but not all rectangles are squares. Impassioned arguments are not lesser.
