Incentive-Compatible Societies: Formal Environment Design for Truthful Meta-Knowledge

The core claim of Eisenstein et al. is that incentive structure yields meta-knowledge. We push this further by applying formal environment engineering (Gardelli et al., 2006) to specify communication protocols, sanction mechanisms, and audit hooks that render truthful uncertainty reports subgame-perfect. Agents accrue long-run penalties for misleading teammates (e.g., claiming confidence without evidence), enforced via periodic ex-post audits or sampled tool cross-checks. This differs from purely empirical self-play by proving incentive properties of the interaction. Combining Predictive Safety Networks (Guo & Bürger, 2019) adds safety constraints (e.g., mandatory abstention zones), yielding guarantees about safe tool use. The significance is principled mechanism design for multi-agent epistemics, applicable to high-stakes domains surveyed in agentic LLMs (Plaat et al., 2025).
