“Hold the Lessons of History Loosely (Members Newsletter)” — @CedricChin
Why this is in the vault
Cedric’s tacit-knowledge series is the spine of his entire body of work — the argument that expertise in any wicked domain (business, agents, engineering) is pattern-matching that can only be acquired through reps with feedback. This directly shapes how RDCO trains AI agents (deliberate-practice loops) and how we develop the founder’s own deployment expertise.
The core argument
Members-only essay: historical case studies are useful for generating hypotheses about your situation but dangerous as templates. The base rates have shifted; the actors are different; the path-dependence is non-replicable. Hold the lessons loosely — as inputs to judgment, not substitutes for it.
Mapping against Ray Data Co
Two load-bearing applications: (1) Agent training methodology — agents need the same perceptual-exposure + feedback-loop structure Cedric describes for human experts; we’re explicit about this in our agent-deployer pitch. (2) The founder’s own learning loop — every client deployment is a rep, the vault is the playback, Sanity Check is the forcing function for articulating what was learned.
