What is priority reassessment system?

Priority reassessment system is a concept in personal epistemology: Priorities change as circumstances change — reassess regularly not just once.

Example: You set your quarterly priorities in January: launch the new product feature, hire a senior engineer, and write the technical documentation. By mid-February, your lead engineer gives notice, a competitor releases a feature that makes yours irrelevant, and a major client signals interest in a completely different capability. Your January priorities are now artifacts of a world that no longer exists. But you keep working the original list because you committed to it — because changing feels like failure, and the planning session took two full days, and everyone saw the slide deck. You finish the quarter having executed your plan flawlessly and accomplished nothing that matters. Now imagine instead that you had built a reassessment trigger into your priority system: any time a significant input changes — personnel, market, client signal, personal circumstance — you pause and ask, 'Given what I know now, are these still the right priorities in the right order?' In February, that question would have redirected your entire quarter toward the opportunity that actually existed rather than the one you imagined in January.

This concept is part of Phase 35 (Priority Systems) in the How to Think curriculum, which builds the epistemic infrastructure for priority systems.
