I've personally be satisfied with what I'll call "informed" common sense. An example from health is the documentary "In Defense of Food" where the journalist uses a little science and history to create the heuristic: "Eat food, mostly plants, not too much." None of those insights are really surprising, the only exception maybe being the "mostly plants part".

A downside of depending on complicated theories from experts is that it makes a "priesthood" of people telling you what to think all the time. I think there are enough examples from health, environmental, and privacy policy making to demonstrate that the "priests" don't always have the public's best interests in mind.
