Earlier I noted research that showed that economists agree ..... a lot. Now Justin Wolfers has to go and do the predictable and claim that economists disagree .... a lot.
But perhaps the best comment on the agree/disagree divide comes from Bryan Caplan when he writes,
Who's closer to the truth about economists' ideological divide: Dahl and Gordon, or Wolfers? My answer: it heavily depends on whether or not your sample includes the broader public. Compared to non-economists, economists enjoy an amazing consensus. But if you only compare us to one another, we're a contentious tribe.
