This premise conflates intelligence with accuracy, success, and competence. Intelligence has some relationships with those things but is none of them in itself. Many highly intelligent people can also be totally incompetent in various contexts as well as highly unsuccessful and/or inaccurate. Intelligence alone does not replace experience, education, and, dare I say, wisdom. You are displaying a clear overvaluation and positive bias for intellect and intelligence over all the things which must compliment it for it to manifest and work in the world. thundax

Intelligence alone does not determine whether an individual knows what's best for a country. In fact, "what's best" is an at least somewhat subjective notion in itself and people of various sorts, including those of similar intellect will disagree about "what's best". thundax
