The American Management Association published an excerpt from William A. Cohen’s book A Class with Drucker:
“I never ask these questions or approach these assignments based on my knowledge and experience in these industries,” answered Drucker. “It is exactly the opposite. I do not use my knowledge and experience at all. I bring my ignorance to the situation. Ignorance is the most important component for helping others to solve any problem in any industry.”
Hands shot up around the room, but Drucker waved them off. “Ignorance is not such a bad thing if one knows how to use it,” he continued, “and all managers must learn how to do this. You must frequently approach problems with your ignorance; not what you think you know from past experience, because not infrequently, what you think you know is wrong.”
Cohen continues with a story about Americans building British cargo ships during World War II without having any knowledge about building ships.
Ramsay, who works out of a spare bedroom in the wilds of southwest England, has never read a book about submarines. “You would just end up totally tainted in the way you think,” he said. “I just work out what it’s got to do, and then come up with a solution to it.”
Elon Musk, quoted in one of Tim Urban’s amazing articles:
I think generally people’s thinking process is too bound by convention or analogy to prior experiences. It’s rare that people try to think of something on a first principles basis. They’ll say, “We’ll do that because it’s always been done that way.” Or they’ll not do it because “Well, nobody’s ever done that, so it must not be good.” But that’s just a ridiculous way to think. You have to build up the reasoning from the ground up—“from the first principles” is the phrase that’s used in physics. You look at the fundamentals and construct your reasoning from that, and then you see if you have a conclusion that works or doesn’t work, and it may or may not be different from what people have done in the past.
Ben Taub of The New Yorker followed Victor Vescovo who managed to dive to the deepest point of every ocean:
“Patrick retrieves a piece of equipment from the deepest point on earth, and it’s just me, going, ‘Yay, congratulations, Patrick.’ No one seemed to notice how big a deal it is that they had already made this normal—even though it’s not. It’s the equivalent of having a daily flight to the moon.” McCallum, in his pre-dive briefings, started listing “complacency” as a hazard.
“It’s quite mind-blowing, when you sit down and think about it, that, from the dawn of time until this Monday, there were three people who have been down there,” he said. “Then, in the last ten days, we’ve put five more people down there, and it’s not even a big deal.”
