Principlev1
Measure environmental impact using predetermined metrics
Measure environmental impact using predetermined metrics recorded at fixed intervals during the experience, not retrospective assessments after the experience ends.
Why This Is a Principle
This follows from memory being reconstructive (Memory is reconstructive, not reproductive—humans rebuild), retrospective memory diverging from real-time experience (Retrospective memory of experience diverges systematically), and hindsight bias shifting memories toward outcomes (Hindsight Bias and Calibration Necessity). In-the-moment measurement captures actual experience rather than reconstructed narratives.
