Open-Strategy Dictator Game Shows Conditional Cooperation Dominates
A recent study published on arXiv (2608.14913) introduces the Open-Strategy Dictator Game (OSDG), a modified version of the traditional dictator game where players' strategies are documented in natural language. In this setup, the dictator's choice to either share or retain an endowment may hinge on the strategy employed by the recipient, with a large language model facilitating the interpretation of these interactions. The researchers organized round-robin tournaments featuring various strategies, examining the payoff matrix through softmax equilibrium frequencies and dominance analysis. Findings indicate that conditionally cooperative strategies prevail, while unconditional strategies are weakly dominated, highlighting the strength of conditional cooperation in transparent strategic environments. This research has significant implications for cooperation within AI and multi-agent systems.
Key facts
- The Open-Strategy Dictator Game (OSDG) is a variant of the classic dictator game.
- Each player's strategy is a natural-language document visible to all participants.
- The dictator's decision to share or take an endowment may depend on the recipient's strategy text.
- A large language model adjudicates each interaction by interpreting strategies.
- Round-robin tournaments were run among diverse strategies.
- Payoff matrix was analyzed using softmax equilibrium frequencies, dominance analysis, and sensitivity analysis.
- Conditionally cooperative strategies consistently dominate.
- Unconditional strategies (always share or always take) are weakly dominated.
- The study suggests conditional cooperation emerges in transparent environments.
- The paper is available on arXiv with ID 2608.14913.
