It depends on what you mean by "the super-intelligent". For my part I always assume it means m̶a̶t̶h̶e̶m̶a̶t̶i̶c̶a̶l̶ p̶h̶y̶s̶i̶c̶i̶s̶t̶s̶ a broad range of the well-educated, so that all bases are covered and the "blind spots" pixie quite rightly mentions are (as far as possible) covered. I don't agree with the premise of Khandro's comment that "intelligent" people are, generally, inept in other important areas. At the very least, even if you accept that political decisions should be guided by instinct as well as by evidence, I fear the latter is playing a far smaller role than it should do at the moment.
Just to add, in case there were any doubt, that saying "I prefer to think for myself" naturally exposes me to being wrong, perhaps fairly often.
