Mental Models
The frameworks behind exceptional thinking
A mental model is a simplified picture of how something works. The models you hold decide what you see, predict and decide, and most of them were absorbed, not chosen.
The idea in brief

-
Models are absorbed, not chosen
They come from a first job, a mentor, one early success, one failure, or an industry that quietly taught you what normal looks like. They run whether or not you know they are there.

-
