What is version control thinking?

Version control thinking is a concept in personal epistemology: Label your schema versions so you can compare current thinking to past thinking.

Example: You believed 'hiring for culture fit is essential' in 2023. By late 2024, after three bad hires who fit culturally but lacked critical skills, your belief shifted to 'hire for capability, then cultivate culture.' Without version labels, you cannot see the trajectory: v1.0 was naive, v1.1 added nuance, v2.0 was a full rewrite. With them, you have a changelog of your own cognition.

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