I've seen it theorized that a majority, roughly ~80% or so, are inclined to go along with the status quo, whatever it happens to be. While a relatively smaller minority of radicals of various types ~10-20% compete with each other, dragging the majority along with whatever group wins out. So they say, it's really just a small group of various radicals, ideologues, thinkers, visionaries, etc, fighting for control of the same subset of ~10-20% of people. The majority goes along with the minority perceived to be the most convincing, dominate, etc. If that theory is true, then all we'd need to do is win over enough "fringe" types to become the dominate intellectual/ideological force among the minority, and the rest will more or less go along with the new status quo. That's doable. I don't know if that theory has any merit, but if so, could explain how a relatively small minority of intellectual neoconservatives, progressives, etc, could come to dominate the intellectual sphere, even though they aren't the majority.
At any rate, I don't doubt the political class has given a lot of thought to this question... why else would they be funding studies analyzing social patterns and democracy in animals, fish, etc? If you can find out how majority populations make decisions, there would be a lot of power in that, I would imagine.
