A conversation with the father/grandfather of family friends was about the need of intellectuals in politics. If he meant intellectual as in a natural philosopher which we typically refer to now as scientists, then I would agree. Then again, I really like the flow of try, analyze results, and determine if successful or not. Also, the idea of double blind testing and other measures to achieve objectivity. These are all things rarely seen in politics.
But then again, some people want a leader who is certain. Someone whose bearing means to them they have a handle on the situation to improve things. Never mind that confidence under pressure does not equate to making well reasoned or even successful decisions.
