All these mental models are simplified maps of an infinitely complex reality. When we rely on them too heavily, do we risk falling into the trap of mistaking the map for the actual territory? The very tools we use to understand the world can end up shaping and even limiting our perspective. That's why being aware of the limitations of the models themselves is just as important as using them.

The version from 2018 seems to have been replaced with an AI-generated copy of itself for whatever reason.

You can use the Wayback Machine to read the version that was originally discussed.

Thanks for confirming. I liked the clarity of outline but the AI-speak of the prose was really a slog.

My mental model of a website that replaces the content with some 'sign up now' stuff while I'm trying to read it is that it deserves to get closed and never looked-at again.

My mental model is ignoring people who complain about free stuff

Ohhhh it's free! Let's shove it up the arse!!!!

Yeah yeah, like someone is doing charity here.

True, how free is something really when it’s full of advertisement, trackers and popups

FS was a major part of me getting into Munger and building out my web of mental models.

Will always be grateful to Shane for that!

Recommendations of things to read in that vein?

The Wit and Wisdom of Charlie Munger is a good place to start.

Shane's mental models books are packed with a lot of random/disparate domains/insights -- He's a good aggregator there.

Thinking in Systems by Meadows.

Really, once you go down the rabbit hole, you find new threads to pull. That's kind of the fun of it

Books by Peter Bevelin (From Darwin to Munger etc.) or Rolf Dobelli are decent compilations. But mental models are everywhere. Taleb's books have a bunch. But start with what you have in front of you: pick one and actually apply it programmatically, then add to your repertoire one at a time.

Bought his books, definitely the first time I was exposed to this sort of stuff. Great reads

It's sad to me that people are apparently so allergic to the term "theory" that we had to come up with this lesser version of it. I guess the key difference is that "mental model" might emphasize dynamics more strongly, which is a flaw in my opinion (logical relationship is what matters, whether those relations are static or dynamic).

> It's sad to me that people are apparently so allergic to the term "theory" that we had to come up with this lesser version of it.

There's an argument to be made that it is useful to distinguish between mental models and theories.

If a theory is a structured, formal explanation of phenomena, grounded in evidence, logic, and often mathematics that is meant to be shared, tested, and and falsified, a mental model is more of an internal representation of how something works, often informal, simplified, personal, and built to help you reason, predict, and decide.

I find both tools useful, but different.

LOL. I was looking for an about link to learn who the author is, but there’s isn’t one. The more I scrolled the more I kept seeing these book covers all with the name. So I guess that stands for “about” link. Cheeky.

But what I really wanted to say, this reminds me of Scott E Page’s Coursera course on Model Thinking, and a book: “The Model Thinker What You Need to Know to Make Data Work for You” also from 2018.

They seem to be being a bit naughty with the attribution. This is all based of the ideas of Charlie Munger who featured more prominently if you look at an archive version of the same page https://web.archive.org/web/20180215045353/https://fs.blog/m...

A transcript of Charlie's speech is still up https://fs.blog/great-talks/a-lesson-on-worldly-wisdom/

I guess Shane Parrish is trying to carry the torch on now that Charlie has passed.
