Useful Mental Models

Gabriel Weinberg has a great Medium post about Useful Mental Models. ‘There is a much smaller set of concepts, however, that come up repeatedly in day-to-day decision making, problem solving, and truth seeking. As [Charlie] Munger says, “80 or 90 important models will carry about 90% of the freight in making you a world­ly‑­wise person.”’ He notes ‘my definition of mental model differs from some others, with mine being more broadly defined as any concept that helps explain, analyze, or navigate the world.’
