From Situational to Unconditional: The Spectrum of Moral Commitment Required for Multi-Agent Survival in Non-linear Social Dilemmas

Key Points

To explore the relationship between environmental conditions and the required moral commitment for survival in multi-agent systems.
Developed the Moral Commitment Spectrum to categorize moral commitments.
Analyzed survival rates in linear and non-linear public goods game environments.
Tested decentralized baselines under various conditions for survival outcomes.
Conducted a large-scale test with 100 agents to evaluate key hypotheses.
Situational commitment succeeds in linear environments but fails in non-linear ones.
In non-linear scenarios, pure reinforcement learning results in only 5.3% survival.
Unconditional commitment guarantees survival at a level of φ1*=1.0.
Decentralized baselines like Inequity Aversion achieve 0% survival under certain conditions.

Abstract

We establish the Moral Commitment Spectrum: a systematic relationship between environmental severity and the minimum moral commitment required for multi-agent system survival. In linear PGG environments, situational commitment achieves group-level ESS. In non-linear environments with catastrophic tipping points, pure RL fails (Nash Trap at λ≈0. 5, 5. 3% survival), and only unconditional commitment (φ1*=1. 0) guarantees survival. Key findings: Decentralized baselines (Inequity Aversion, Social Influence) achieve 0% survival under Byzantine conditions—their other-regarding mechanisms cause downward drift toward adversaries' zero contributions. Only unconditional commitment is structurally immune. v2. 0. 0 (2026-02-28): Unified paper integrating Paper 1 (Situational Commitment) + Paper 2 (Nash Trap).
