In today's WSJ, George Mason University economist Daniel Klein codifies as much. Klein summarizes results of a recent survey to assess the grasp of economics found among different political groups. Asked eight questions reflecting basic economics, self-described adherents to various political ideologies missed the following numbers of questions, on average:
Very conservative, 1.30; Libertarian, 1.38; Conservative, 1.67; Moderate, 3.67; Liberal, 4.69; Progressive/very liberal, 5.26.
N.B. that the questions were given on a five-point Likert scale, and three of five responses were scored correct for each answer. That means that the left did worse than random guessing. It also means that noble, principled Moderates (read: confused and indifferent) are only slightly worse than random guessers.
Go ahead, Lefties: carp about the nature of the questions or the validity of the survey. The rest of us will try to get on with dealing with the grim reality.
