Pat Dorsey’s Moats Mindmapped

Few months back I mind mapped Charlie Munger’s psychology of human misjudgment. You can take a look at it here. Mind maps are really powerful as it organizes information visually and it aids the associative nature of human brain. In this post I have mind mapped four different types of moats which Pat Dorsey talks about in his fantastic book The Little Book That Builds Wealth. Recently he gave a talk about moats at Google. It’s simply the best and I highly recommend watching it.


Few things to note before you look at the mind maps (1) In order to understand the mind maps you should have read Pat Dorsey’s book (2) Click on the mind map (3) Enlarge the mind map to view it clearly (4) Read them in clockwise direction (5) Repeat several times (6) When you study a business come back to this and see which moat(s) applies to your business.

1. Intangible Assets


2. Switching Costs


3. Network Effects


4. Cost Advantages
