Mental Models? Latticework? Huh? Do what now?
The phrase ‘Latticework of Mental Models’ comes from Berkshire-Hathaway’s Charles Munger, who is a person that has spent most of his life working out ways to, for lack of a better term, think better.
Munger has come to the conclusion that in order to make better decisions in business and in life, you must find and understand the core principles from all disciplines.
In short, learn all the big ideas and how they interrelate and better, more rational thinking will naturally follow.
This is what he calls Elementary Worldly Wisdom, and using his system of Mental Models can help you succeed in almost any endeavor.

Worldy Wisdom Means Ignoring Boundaries
Munger is big on reading and light on the boundaries separating disciplines. He relishes taking core ideas from one discipline and using them to solve problems in another, often doing it better than those who believe the disciplines are separate and not related.
He is often quoted as saying ‘to a man with a hammer everything looks like a nail‘ and strongly recommends a mental toolbox filled with an array of tools.
Filling The Toolbox
Charlie has never provided a full list of the models he has collected in his lifetime, though he has provided some and has hinted at others.
This suggests that he believes the quest to find these models is an important part of the path to better thinking. However, this means that those of us that want to learn more are left to our own devices.
So how do we start to acquire them?
Start With The Master Himself
What better place to start than with the words of Charlie himself?
On my Getting Started page I have links to a couple of his speeches (the best ones, in my opinion). You can find them here:
Read (a lot of) Books
We also know Charlie reads a lot. I mean a lot. And in order to build my own set of mental models I try to do the same and read as much as I can.
If you want to see the books I’ve read that have helped me learn the most mental models then head over and check out this list of my favorites:
Or if you want to see what Charlie has been reading, take a look at this extensive list of books he has recommended:
Alternatively, you can read about his friend and business partner Warren Buffett:
You will also want to be efficient with your reading so that you don't waste time on books that are mostly fluff. Learn how I'm able to read more books in the same amount of time:
Fill In the Blanks
Sometimes simply reading about an idea isn't enough for us to 'get' it.
When this happens to me, I search Udemy for a video that covers the idea in order to get a different perspective.
Below are the Udemy videos that I've found to be the most helpful.
Learn (copy) From Other Munger Fans
You're not alone in trying to follow in his footsteps, so why not collaborate and learn from other people who are trying to learn the same mental models?
While I haven't collected all of Charlie Munger's mental models, I have put together a checklist of the 83 I have found so far.
You can download them for free as a one-page PDF simply by joining my mental models mailing list:

Let's start a discussion below about Charlie and mental models.
If you have a model you use a lot, or one you are struggling to understand, post a comment below and we can all start to learn from each other and move forward together.
I believe getting an MBA is one of the best ways to start building mental models.
Well getting an MBA isn’t necessary for you to start building mental models. Josh Kaufman is a good example
i think mental models are awsome
Hi Andrew,
Great post. I’ve recently taken interest in the concept of mental models and your article helped provide a good start towards learning and building this lattice network of ideas. However, I do have a couple questions about acquiring these knowledge.
How do you know which mental models you should acquire for a particular skill/analysis? For example: In economics, say particularly for studying monetary policies. How do you go about building a checklist for this? Do you just read lots of related books and hopefully come across some ideas that fit? What kind of process do you use to systematically decide which mental models are important and essential for what you’re trying to study?
Appreciate the feedback. I’m looking forward to reading and gaining insights from your coming newsletters!
