What is peer review process?

Peer review process is a concept in personal epistemology: Having trusted people review your mental models catches errors you miss.

Example: A software engineer believes her team's velocity problems stem from unclear requirements. She has refined this schema over months, and it feels airtight. When she presents it to a trusted peer in a different organization, he asks a single question: "Have you considered that your team actually understands the requirements fine but disagrees about priorities?" She realizes she has been interpreting every planning friction as a comprehension failure because her own strength is specification writing. A schema that felt complete from the inside had a structural blind spot that only another mind could see.

This concept is part of Phase 15 (Schema Validation) in the How to Think curriculum, which builds the epistemic infrastructure for schema validation.
