SCORE

Retest the exact function you measured before, plus the real-world task result, against your prediction; feeling calmer alone doesn't count.

Before your study session you noticed you couldn't hold a single page of the statistics textbook, so you took a 15-minute walk. Back at the desk, you feel noticeably better, and here is exactly where most people declare victory and learn nothing.

SCORE says: feeling calmer alone doesn't count. Retest the precise function you measured before, against the prediction you made. The operation: return to the same test, in this case reading that same page and checking whether it holds together; then check the real-world task result, did you actually work through the practice problem; then compare both against what you predicted the walk would do. Record comfort separately if you like, but it is not the score. Three honest outcomes follow. The function returned: credit the support and keep the pairing for next time. Unchanged despite feeling better: the walk was pleasant but the real limiter is something else, maybe a missing concept from chapter four, so chase that instead of repeating walks. Worse: stop that support for this situation. What changes over time is compounding self-knowledge, since scored experiments teach you what actually restores your thinking, while unscored ones just build comforting rituals. Never swap in a friendlier metric after the fact; that quietly destroys everything the test could teach you.
