Drum on Menand on Tetlock’s ‘Expert Political Judgment: How Good Is It?’

I really liked Kevin Drum’s droll snark at the end of his item on Louis Menand’s review in the New Yorker of Philip Tetlock’s new book, Expert Political Judgment: How Good Is It? How Can We Know?: Foxes and hedgehogs.

So there’s your lesson for the day. Avoid ideologues on both left and right. Stay away from people who have unshakable faith in their convictions. The more confident someone sounds, the more likely they are to be wrong. Steer clear of cranks with big theories. Pay more attention to statistical and actuarial formulas than to expert opinion. And ignore the folks at Power Line. They aren’t due to be right again for a long time.

Sounds like a pretty solid set of guidelines.
