"People tend to be clueless about prices. Contrary to economic theory, we don't really decide between A and B by consulting our invisible price tags and purchasing the one that yields the higher utility, he says. We make do with guesstimates and a vague recollection of what things are “supposed to cost.”"

Highly intelligent and well-informed people disagree on every political issue. Therefore, intelligence and knowledge are useless for making decisions, because if any of that stuff helped, then all the smart people would have the same opinions. So use your "gut instinct" to make voting choices. That is exactly like being clueless, but with the added advantage that you'll feel as if your random vote preserved democracy.
