What is commitment contracts?

Commitment contracts is a concept in personal epistemology: An unwritten commitment is an invitation for your future self to renegotiate. Externalized commitments become binding infrastructure — visible, trackable, and resistant to the drift that lives between intention and action.

Example: You tell a colleague you'll review their architecture doc by Friday. The commitment lives only in your head. By Wednesday, three urgent tickets have pushed it out of working memory entirely. Friday arrives. You've broken a promise you genuinely meant to keep — not from malice, but from the structural failure of storing commitments in the same volatile memory that processes everything else. Now write that commitment in a system your future self will encounter: a task manager, a calendar block, a shared document. The commitment becomes an object in the world, not a hope in your head.

This concept is part of Phase 10 (Externalization Mastery) in the How to Think curriculum, which builds the epistemic infrastructure for externalization mastery.
