Mental Models

with one comment

The title of this blog is based on a quote from Charlie Munger about getting worldly wisdom from having a number of mental models

In multiple speeches, and in the book Poor Charlie’s Almanack, Munger has introduced the concept of “Elementary, Worldly Wisdom” as it relates to business and finance. Munger’s worldly wisdom consists of a set of mental models framed as a latticework to help solve critical business problems. According to Munger, only 80 or 90 important models will carry about 90% of the freight in making you a worldly-wise person.

Conveniently Farnam Street posts daily about mental models, and provides a pretty complete list below.
