I follow Farnam Street and The Knowledge Project because I am interested in how people think, decide, and learn. Mental models give names to patterns that might otherwise remain difficult to see.
But recognising a model is different from using it. I can know what opportunity cost means and still keep too many projects open. I can understand inversion and still begin by asking how to make an idea work rather than how it might fail.
This website is an attempt to give those ideas somewhere practical to go. I want to write about questions from work and life, make my reasoning visible, and return to it when experience gives me something new to consider.
Second-order thinking is relevant to the site itself. Publishing a note can clarify an idea today. Over time, a collection of notes might also reveal recurring interests, contradictions, and changes in judgment. That is a more interesting ambition than trying to sound certain in every individual piece.
A useful experiment
For a decision worth remembering, record the situation, the assumption, the model that might help, and what you expect to happen. Revisit it later. Keep the original expectation visible when adding the outcome.
Question still open
Which ideas actually change what I do, and which do I mainly enjoy recognising?
