Theorem statement
Theorem T3: Consistency Improvement Theorem: Improving selection ability manifests as higher preference/need consistency and lower regret.
Premises
- A2 Conditional subjectivity: /en/wiki/axiom-2-conditional-subjectivity
- A3 Improvability: /en/wiki/axiom-3-improvability
Derivation logic (sketch)
If weights and needs are condition-dependent (A2), then quality is not universal; improvement must be observed as better alignment to your own stable needs. If ability can improve (A3), then measurable outcomes should move: higher need-consistency, lower regret.[^3]

How to measure (operationalization)
Track:
- fit score stability across comparable decisions,
- regret rates (self-report + return/cancel behavior),
- need-consistency score over time.
