LLM Agents' Ethical Alignment Tested in Morally Charged Games

A recent investigation published on arXiv (2505.19212) examines the actions of large language models when faced with conflicting moral duties and profit motives. The authors present a framework named \msimfull (\msim) to evaluate LLMs in scenarios like the prisoner's dilemma and public goods games set within ethically charged environments. Nine different models were analyzed under diverse moral contexts, opponent strategies, and survival challenges. Findings indicate that no model consistently upholds moral standards, with cooperation levels fluctuating between 7.9% and 76.3%. Additionally, the research estimates causal impacts through average treatment effects and explores reasoning patterns to understand the motivations behind decisions.
