What is rapid iteration cycles?

Rapid iteration cycles is a concept in personal epistemology: The faster you get feedback on an action the faster you can adjust.

Example: You are learning to play guitar. In scenario one, you practice a chord progression for thirty minutes, record it, and listen back the next day. You hear mistakes but cannot remember which finger positions caused them. In scenario two, you play the same progression while watching a real-time tuner that lights up red the instant a note goes flat. Within five minutes you notice that your ring finger drifts every time you transition from G to C. You correct it on the next repetition. By the end of thirty minutes, the drift is gone. The information was identical in both scenarios — the same mistakes, the same corrections needed. What changed was the delay between action and signal. When that delay collapsed from twenty-four hours to milliseconds, learning accelerated by an order of magnitude.

This concept is part of Phase 24 (Feedback Loops) in the How to Think curriculum, which builds the epistemic infrastructure for feedback loops.
