Selection ability can be improved via learning, feedback, and method iteration.

Aliases: A3, Improvability, Learnability axiom

Axiom statement

Axiom A3: Improvability: Selection ability can be improved via learning, feedback, and method iteration.


Detailed explanation

If selection ability can improve, then:
- methods are first-class objects (we can compare methods),
- validation matters (we need feedback signals),
- learning loops can outperform one-shot “perfect research.”[^1]


What it derives

A3 supports:
- T2 Cognitive budget (with A1): /en/wiki/theorem-2-cognitive-budget
- T3 Consistency improvement (with A2): /en/wiki/theorem-3-consistency
- T4 Selection efficacy (with A1 + A2): /en/wiki/theorem-4-selection-efficacy


Operationalization (how to test improvement)

Track across repeated decisions:
- regret rate,
- need-consistency,
- time/attention cost,
- fit score stability.[^2]
