step two: encircle your problem with existing answers to similar questions, and then deduce what it is that the answers have in common—in fact, if you’re a true expert, “your mental matrix will be filled with P’s and S’s,” a vocabulary of questions already answered. Call it ingenious incrementalism—or, as Shannon put it, “It seems to be much easier to make two small jumps than the one big jump in any kind of mental thinking.”
