“A Framework for Putting Mental Models to Practice” — @CedricChin

Why this is in the vault

Anchor piece in Cedric’s argument that mental-model collecting is intellectually pleasurable but action-useless — only practitioners can transmit usable models, and the test is downstream skill, not crisp explanation. Directly informs how Sanity Check is written and how we evaluate other thought-leaders for the vault.

The core argument

Members-only piece sketching how mental models actually become useful: by being attached to specific, rep-able decision contexts where you can get fast feedback. The framework is essentially Cedric’s operationalisation of his Mental Model Fallacy critique — here’s what to do instead of collecting models.

Mapping against Ray Data Co

The Mental Model Fallacy is the reason Sanity Check refuses to publish ‘N mental models for data engineers’ listicles. Our editorial bar: every piece must come from a deployment we ran, a client conversation we had, or a vault contradiction we resolved — not from re-packaging someone else’s framework. This piece is the canonical citation when explaining that bar to writers/contributors.
