Question
What is distinguishing signal from noise?
Quick Answer
Not every recurring event is meaningful — some repetitions are coincidental.
Example: You notice you've had three bad meetings on Tuesdays and conclude 'Tuesdays are my worst day.' But you've had 200 Tuesday meetings total — three bad ones is a 1.5% rate, no different from any other day. You detected a pattern, but the pattern was noise. A signal pattern would be: every meeting where you skipped your 10-minute prep routine went poorly, regardless of the day. One pattern is coincidence dressed as insight. The other is a structural cause you can act on.
This concept is part of Pattern Recognition in the How to Think curriculum.

After completing this path you will run a working signal cascade: a decision-anchored definition of signal (a difference that makes a difference to a decision you own), gates tuned by position (recall at the bottom, precision at the top), knowledge stored as six-field self-validating artifacts, contradictions surfaced at save time, AI output supervised by exception with alarm-audited gates, verification debt tracked and paid down, and sessions run as thin slices with one question, a bounded working set, and an exit artifact.
