William Kristol on the importance of admitting we don't know. An excerpt:
So I hope the best and the brightest who will be joining the new president will at least entertain the possibility that a lot of what they think they know is wrong. I trust they’ll remember that successful economic policies in the past have pulled together elements from unlikely sources, and that they’re as likely to find wisdom from reading political economists like Friedrich Hayek or Joseph Schumpeter, or Keynes himself, as from poring over the latest academic paper in a peer-refereed economics journal.
