The Charlie Munger
Framework
Mental Models & Latticework Thinking
Charlie Munger built his fortune not by knowing more about business than anyone else, but by knowing enough about every discipline — psychology, physics, economics, biology — to recognise a good decision from many angles simultaneously. He called this 'a latticework of mental models'. This framework captures his core library of cross-disciplinary tools and, crucially, his signature technique of inversion.
A glimpse of Charlie Munger's thinking.
True wisdom comes from understanding the big ideas from all major disciplines and seeing how they interconnect—what Munger calls "latticework thinking." Most spectacular failures come from psychological biases and single-variable analysis, while great decisions emerge from inversion (thinking backwards from failure) and probabilistic reasoning across multiple mental models.
