Everything Charlie Munger has said about mental models
Munger argues that sound judgment requires a latticework of big ideas drawn from every major discipline — including a self-built checklist of the standard psychological misjudgments — practiced routinely rather than recited. He treats this wisdom acquisition as a lifelong moral duty, not a career tactic.

How the view evolved
Built his own misjudgment checklist → Big ideas beat narrow expertise
In 1995 the psychology model set is presented as a homemade fix — Munger recounts jury-rigging 'my own system of psychology' because Harvard left him ignorant and the textbooks had holes. By 2020 at Caltech it has hardened into settled infrastructure — 'that's just my system' — used routinely in judgments, with the indignation at academia mellowed into a wry diagnosis of over-specialization.

“Well, you can say everybody knows that. Well, I think I've been in the top 5% of my age cohort all my life in understanding the power of incentives, and all my life I've underestimated it. And never a year passes but I get some surprise that pushes my limit a little farther.”

“Wealth is the thing that you really want. Wealth is assets that earn while you sleep. Wealth is the factory that with the robots as cranking out things. Wealth is the computer program that's running at night that's serving other customers. Wealth is even money in the bank that is being reinvested into other assets and into other businesses. Even a house can be a form of wealth, because you can rent it out — although that's probably a lower use of productivity — but land and actually doing some commercial enterprise. So my definition of wealth is much more businesses and assets that can earn while you sleep.”

“The observation is that don't die is the most played game by everyone all over the world every day. You and I breathe every few seconds, we look both ways before we cross the street, we all play don't die. So it's played more than capitalism, it's played more than any religion. It's the most played game in the world.”

“It turns out it's not that important to be smart; it's much, much more important to be determined. If you imagine this hypothetical person who's like a hundred out of a hundred for smart and a hundred out of a hundred for determination, and then you start taking away determination, it doesn't take very long before you have this sort of ineffectual but brilliant person. Whereas if you take someone who's super, super determined and you start taking away smartness bit by bit, eventually you get to some guy who owns a lot of taxi medallions — but he's still rich. Or like a trash hauling business or something like that.”
