The best way to be well received by all is to clothe yourself in the skin of the dumbest of brutes.
—Baltasar Gracián
The feeling that someone else is more intelligent than we are is almost intolerable. We usually try to justify it in different ways: “He only has book knowledge, whereas I have real knowledge.” “Her parents paid for her to get a good education. If my parents had had as much money, if I had been as privileged . . . ” “He’s not as smart as he thinks.” Last but not least: “She may know her narrow little field better than I do, but beyond that she’s really not smart at all. Even Einstein was a boob outside physics.” Given how important the idea of intelligence is to most people’s vanity, it is critical never inadvertently to insult or impugn a person’s brain power. That is an unforgivable sin. But if you can make this iron rule work for you, it opens up all sorts of avenues of deception. The feeling of intellectual superiority you give them will disarm their suspicion-muscles.
Daily Law: Subliminally reassure people that they are more intelligent than you are, or even that you are a bit of a moron, and you can run rings around them.
