What is commitment architecture?

Commitment architecture is a concept in personal epistemology: Willpower alone cannot sustain commitments — you need structural support.

Example: You commit to writing every morning. For three days, it works. On day four, you sleep badly, your inbox is full, and a meeting got moved to 7am. You skip writing 'just today.' By day ten, the commitment is gone. Nothing about your desire changed. What failed was the absence of structure: no protected time block, no environment cleared for writing, no pre-commitment that made skipping harder than following through. The commitment was real. The architecture was missing.

This concept is part of Phase 34 (Commitment Architecture) in the How to Think curriculum, which builds the epistemic infrastructure for commitment architecture.
