My experience is that smart people more often refrain from judgement of intelligence in others. Those that judge quickly, especially after a single statement that may have been stupendous or trivially illogical, almost certainly aren't the brightest stars in the night sky. That includes excentric people, perhaps not those that state something like that in an overly emotional state. But otherwise it is quite a good giveaway in my opinion. Especially if you ask them to elaborate their disagreement, the argument is often trite and one-dimensional.
