What is reassessment signals?

Reassessment signals is a concept in personal epistemology: Define specific signals that should prompt you to re-evaluate a schema.

Example: A product manager ran every sprint planning through the same prioritization framework for eighteen months. Customer churn doubled in Q3. She didn't review the framework — not because she was lazy, but because nothing in her system flagged the churn spike as a trigger to question prioritization. The schema wasn't wrong when she adopted it. The market shifted, and she had no tripwire to catch it.

This concept is part of Phase 16 (Schema Evolution) in the How to Think curriculum, which builds the epistemic infrastructure for schema evolution.
