What is output checklist pre-delivery error prevention?

Output checklist pre-delivery error prevention is a concept in personal epistemology: A pre-delivery checklist catches errors before outputs reach their audience.

Example: Before sending a client strategy memo, you run it through your five-item output checklist — audience clarity, core claim stated first, evidence linked, formatting clean, call to action explicit — and catch that you buried the recommendation on page three instead of leading with it.

This concept is part of Phase 44 (Output Systems) in the How to Think curriculum, which builds the epistemic infrastructure for output systems.
