The tragedy of Xerxes and Artabanus is that each lacked the other’s proficiency. The king, like Tetlock’s hedgehogs, commanded the attention of audiences but tended to dig himself into holes. The adviser, like Tetlock’s foxes, avoided the holes, but couldn’t retain audiences. Xerxes was right. If you try to anticipate everything, you’ll risk not accomplishing anything. But so was Artabanus. If you fail to prepare for all that might happen, you’ll ensure that some of it will.
