"Seek Ideas At The Right Level of Abstraction" — @CedricChin

Why this is in the vault

Foundation epistemology piece — Cedric's argument that frameworks are useful, not true, and that the test is whether they help you act under uncertainty. This shapes how RDCO writes (Sanity Check's anti-framework-cargo-cult bias) and how we run client engagements (we resist deploying methodologies for their own sake).

The core argument

Skill-development claim: choosing the right level of abstraction is itself a skill — too abstract and your reasoning loses contact with reality; too concrete and you can't generalise. Experts can move up and down the abstraction ladder fluidly; novices get stuck at one level.

Mapping against Ray Data Co

Sanity Check's editorial voice is heavily indebted to Cedric's epistemological humility — 'optimise for usefulness' is essentially our north star vs. the LinkedIn-thought-leader tendency to package observations as 'frameworks'. When we write about agent deployments, the bar is whether the reader can act differently tomorrow, not whether the post sounds insightful.
