𝗬𝗼𝘂 𝗛𝗮𝘃𝗲 𝗢𝗻𝗲 𝗧𝗼𝗼 During World War II, B.F. Skinner walked into a hearing in front of a committee of the country's top scientists and pitched them a missile flown by a pigeon. He was not kidding. The pigeon nailed it. The committee chuckled. The funding died. His sponsor's advice: "Why don't you go out and get drunk!" Skinner's hammer was reinforcement. It worked on pigeons, so he swung it at everything. Charlie Munger called this man with a hammer syndrome, and he added the part nobody likes: it doesn't exempt bright people. Bright people just own nicer hammers. I sat down with a vendor. I said, our problem is turnover on the leasing team. He goes, our dashboard fixes that. I said, how? He goes, visibility. I said, they can see the problem fine. They're quitting. He goes, then they need more visibility. Ask the CFO and the answer is cut costs, operations wants more staff, marketing wants more ads, and training, naturally, wants more training, so you walk out with four diagnoses for one problem, each one matching the job title of the person who gave it. Me? I used to dream in Excel. If I couldn't model a business in a spreadsheet, I didn't understand it. Great rule, right up until a leasing agent is crying in the parking lot. You can't put that in a cell. I've tried. Now I've got AI too. So my hammer has two heads. Progress. 🤪 Darwin had the antidote. He wrote down every fact that cut against his theory the moment he found it, because he had noticed those were exactly the facts his memory lost first. Charles Darwin, keeping receipts on himself. Munger loved that. Mine's a spreadsheet. What's yours?
