The Great Mental Models (Book Review)

The Great Mental Models: General Thinking Concepts by Shane Parrish (of Farnham Street blog fame) is a short (3,5 hours) read/listen that introduces some awesome and useful mental models. Here a very short summary I found:

Maps are not the territory – All models are wrong, but some are useful
1. Reality is the ultimate update
2. Consider the cartographer
3. Map can influence territory

Circle of competence
If you want to improve your odds of success in life and business then define the perimeter of your circle of competence, and operate inside. Over time, work to expand that circle but never fool yourself about where it stands today, and never be afraid to say “I don’t know.”

Inversion – Approach situation from the opposite end of the natural starting point

Occam’s razor – simpler solutions are more likely to be correct than complex ones. “When you hear hoofbeats, think horses, not zebras”

Hanlon’s razor – Don’t attribute to malice that which is explained by stupidity. It’s less likely for two things to be true than one
