What is multiple perspectives?

Multiple perspectives is a concept in personal epistemology: Seeking other viewpoints shows you what your single perspective cannot.

Example: You design an API and think it's clean. A frontend engineer points out the response shape forces three extra transformations. A security engineer flags an unvalidated parameter you never considered. A customer support lead notes the error messages are meaningless to end users. None of these people are smarter than you — they are differently positioned. Each perspective reveals structure you literally could not see from where you stand.

This concept is part of Phase 5 (Observation Without Judgment) in the How to Think curriculum, which builds the epistemic infrastructure for observation without judgment.
