As much as I personally like and respect Shane from Farnam Street, I don't like the current trend of mental model writing as much. I'm probably one of the more vocal critics, in fact (see: https://commoncog.com/blog/the-mental-model-fallacy/ https://commoncog.com/blog/the-mental-model-fallacy/). The problem with mental models as a thing these days is that it conflates three different things:
1. Frameworks — 'mental model' is often used as a synonym for 'framework', which (as any competent practitioner knows) come with its own set of problems.
2. Thinking Tools — so, things like 'reasoning from first principles'.
3. Mental models, as defined by Piaget & Papert — the original definition of the term, as in 'tacit mental representations of expertise'.
Because mental model writing conflates the three, it can be very difficult to get anything useful out of it. Each of these three categories come with their own strengths and caveats. It is important to separate them.
That said, I think the fad has its benefits: it's led to a resurgence of systems thinking. Which is net good, I think.

- jfarmer 7y agoI'm with you. The way the trend has reduced "mental model" into a synonym for "concept", basically. Everyone wants life hacks, but the value of "model thinking" is to avoid hacks (IMO) by externalizing your cognitive processes and make them more amenable to improvement. One value of models is that they reduce the need for memorization, but blog posts like this ask you to memorize more! The person below who said they have 100s of mental models written down makes me go "?????". Second-order thinking isn't a mental model, it's a way to draw more conclusions out of your models (and therefore conduct more, better experiments). https://twitter.com/jfarmer/status/1225807692561813510 https://twitter.com/jfarmer/status/1225807692561813510
