"The Great Mental Models: General Thinking Concepts" Vol. I - by Farnam Street 4/5
I'm biased here as I have followed Farnam Street's work for quite some time now. I often listen to The Knowledge Project Podcast and I really appreciate what they release.
The book itself is beautiful and I'm glad that I decided to get a physical copy. Its content presents us with only 9 mental models. However, it delivers a lot of examples for each model, with accompanying illustrations and photos, seamlessly blended together.
This is the first volume of the series and it’s focused on general thinking concepts. It’s a great introduction to the world of mental models. Implementing the concepts into our thinking helps us improve our decision making and solve problems better, which is the reason behind the books and the Farnam Street organisation as a whole.
