What is idea evolution?

Idea evolution is a concept in personal epistemology: Ideas evolve. Your system should let you see how any atom changed over time — not just what you believe now, but what you believed before and why it shifted.

Example: In 2019 you wrote a note: 'Remote work reduces productivity.' In 2021, after leading a distributed team through a pandemic, you wrote an updated version: 'Remote work reduces productivity for teams that never built trust in person.' In 2024, a third version: 'Remote work reduces synchronous collaboration; async-native teams outperform co-located ones on complex knowledge work.' Three versions. Each one captures something the previous one missed. None of them are wrong — they are increasingly calibrated. Without the first two versions, you cannot see the trajectory of your own learning.

This concept is part of Phase 2 (Atomicity and Decomposition) in the How to Think curriculum, which builds the epistemic infrastructure for atomicity and decomposition.
