“Human events are too complex to forecast beyond anything but the shortest horizons, yet decisions must be made with an eye to the distant future.

Shared mental models, sometimes called shared narratives, give decision makers the courage to act in the face of such uncertainty and give people the confidence to believe in these decisions.”

There is genuine delight and enjoyment in encountering a new mental model or theory.

A good theory or model gives explanatory power to things gone by and predictive power of things to come.

A theory or model will hold until something occurs that cannot be explained within it.

For example, the theory that “wings and feathers are needed to fly” held pretty well until humans encountered bats (no wings) and tried to fly with feathers and failed.
