The corpus agrees judgment is the scarce resource ([[cross-judgment-scarce-resource]]) — and then agrees it does not yet know how to manufacture it quickly. This is the arc's central *open* problem, and each article proposes a different (unproven) mechanism:

- A043 states the question bluntly: [[question-scaling-judgment]] — Seabrook is only piloting "microskills" with top leaders.
- A032 hypothesizes the [[concept-reasoning-trail]] can build judgment faster than osmotic apprenticeship ([[claim-reasoning-trail-accelerates-judgment]]) — but flags [[question-junior-employee-baseline]]: how does a novice form a valid view at all?
- A046 proposes deliberate practice: [[concept-red-teaming-ai]] and preserved [[concept-intelligent-failures]].
- A051 proposes [[framework-distributed-apprenticeship]] plus engineered [[concept-healthy-friction]].
- A100 proposes immersive simulation ([[action-simulate-enterprise-tradeoffs]], [[question-compressing-experience]]).
- A086 proposes the [[concept-gen-ai-tutor]] — but concedes [[question-complex-teaming-skills]]: AI still can't coach live peer dynamics.

**No mechanism is validated longitudinally.** The shared risk (from [[cross-broken-apprenticeship-pipeline]]) is a five-year lag: firms discover too late that they optimized output and starved judgment. This is the highest-value research gap in the corpus.
