Charlie Munger said the best way to think clearly is to carry a "latticework" of big ideas from many different fields.
One Model at a Time builds that latticework with you, one short episode at a time. Each episode takes a single mental model, like inversion, compounding, Goodhart's law or the Lindy effect, tells the true stories behind it, and shows how to use it in investing, business and everyday decisions, and where it breaks down. A Thousand Bagger show. For education only, not financial advice.
Episode 25: How Did a Plane Crash Invent the Checklist?
In 1935, Boeing's most advanced bomber stalled and crashed on takeoff — not because the plane was bad, but because the pilot forgot a simple step. The answer was a checklist. Today's mental model: when a job has more steps than memory can hold, don't trust memory — write it down. From pilots to a short surgical checklist that cut deaths in a worldwide study, the humble list beats the expert brain.

Episode 24: Does Ice Cream Cause Shark Attacks?
Ice cream sales and shark attacks rise and fall together — so does ice cream cause shark attacks? Of course not; summer causes both. Today's mental model is correlation versus causation: two things moving together doesn't mean one causes the other. Plus a stock market predictor based on butter production in Bangladesh, and why investors keep falling for the same trick.

Episode 23: How Can One Zero Wipe Out Everything?
An investor gains 30 percent a year for five brilliant years, then loses 100 percent in year six. Final result: zero. When things multiply together, one total loss erases everything that came before. Today's mental model is multiplicative systems — and why avoiding the zero matters more than chasing the big win. Plus how one investor's fortune of about 20 billion dollars was reportedly wiped out in a matter of days.
