“A mental model is an explanation of how something works. It is a concept, framework, or worldview that you carry around in your mind to help you interpret the world and understand the relationship between things. Mental models are deeply held beliefs about how the world works…
…To quote Charlie Munger again, ’80 or 90 important models will carry about 90 percent of the freight in making you a worldly-wise person. And, of those, only a mere handful really carry very heavy freight…’
…My hope is to create a list of the most important mental models from a wide range of disciplines and explain them in a way that is not only easy to understand, but also meaningful and practical to the daily life of the average person. With any luck, we can all learn how to think just a little bit better.”
