Charlie Munger on uncommon sense…
Competence – you can only be trusted as competent if you clearly understand the limits of your competence. The great danger of experts is they forget the limits of their expertise – “it is better to trust a man of 130 IQ who thinks he is 125 IQ, than to trust a man of 180 IQ who thinks he is 200 IQ” Warren Buffett
Inverting – if you want to make life better, think of what you would do to make life worse. Charlie was an aviation meteorologist during WWII. His task was to give weather briefings to pilots. His role was unclear until he thought of the inverted perspective “if I wanted to kill pilots as a meteorologist, what could I do? Flying with iced wings, flying in conditions they will be unable to land.” This really clarified for him the important aspects of his role in keeping pilots alive. In our own lives, asking “how would I really make my life worse?” can be a valuable perspective on what really matters.
Collector – be a collector. How many collectors do you know who are unhappy? Identify things or experiences that you enjoy collecting and become a curator of your collections.
Integrate ideas between domains – most people focus on details within the idea (especially academics), few people look at the interaction between big ideas. That’s where there’s not much incentive in academics, but it’s very interesting for investing money.
Occam’s razor- go for simple… with a proviso that was initially shared by Einstein “Everything should be made as simple as possible but not more so” Einstein. Anywhere there is a “lollapalooza result” (Charlie’s term for a hugely positive and rapid outcome)… look for a confluence of causes. Academic experts find one cause. To a man with a hammer, everything looks like a nail. There are rarely just single causes for high impact outcomes.
The problems of Social science– all chemists can answer “where do the rules of chemistry not apply?” In the high temperature plasma state. how many social scientists can answer “if you want to sell more should you raise or lower the price?” Where does this rule not apply? 1 in 50 will say “luxury goods!” Many social scientists forget to think of the exceptional cases.
