Definition
Corollary T3.1: Better Selection Shows as Better Fit: Improvement is observable as higher fit (match) between needs and outcomes.
Derived from
From T3 Consistency Improvement: /en/wiki/theorem-3-consistency
Practical measurement
If a method improves selection, then for comparable decision classes:
- fit scores should increase on average,
- variance should decrease (more predictable matching),
- regret should drop (T3.2).[^2]
