What are the major types of mental models? What should be your focus when learning a mental model?
The many types of mental models cut across several disciplines including math, psychology, economics, physics, and more. They include models like Gaussian distribution, reciprocity, autocatalysis, and opportunity cost. Your focus should be on learning the fundamental meaning of these models and not their nitty-gritty details.
Read on to discover more about the major types of mental models.
The Types of Mental Models
Here’s a list of mental models suggested directly by Munger across his speeches in Poor Charlie’s Almanack. It’s not a complete set of mental models you should know, but it’s a good start to build off of.
Observe a few things about the list:
- It reaches broadly across disciplines that you wouldn’t normally think of interacting, like economics and physics.
- Each discipline has specific ideas that have relevance outside the discipline.
We’ve included links for the different types of mental models under each category as a starting point for research.
The types of mental models include:
- Big “no-brainer” questions
- Patents and trademarks
Get the Core Ideas, Don’t Sweat the Details
For purposes of general cognition, you don’t need to learn the nitty-gritty technical details of the various types of mental models. You need only build an intuition for the fundamental meaning of the mental model.
For instance, for the engineering concept of “margin of safety,” you don’t need to be able to analyze a bridge and calculate the exact margin of safety to five significant figures. Instead, take away the general idea—that a system should have a degree of buffer before it fails.
