Abstract The climate crisis and appeals to tackle it are often framed in moral terms, but few studies tested whether individual variation in moral intuitions correlate with pro-environmental behaviours that may affect the climate commons. In the present study we ask whether moral intuitions regarding harm (care and compassion), fairness, in-group loyalty, stance towards authority, and purity, as quantified by the Moral Foundations Theory, correlate with pro-environmental behaviours. Participants played 10 rounds of a public goods game framed as extraction of a mineral that affects climate commons negatively. We found that participants' extraction in the first round of the game was positively related to loyalty and authority moral foundations. Average extraction over all ten rounds of the game was negatively related to harm and positively related to loyalty moral foundations with small to moderate effect sizes. The fairness dimension was only weakly related to extraction in the first round and not related to average extraction over the entire game. Purity dimension did not relate to extraction neither in the first round nor on average. These results suggest that intrinsic factors such as moral intuitions are likely to play an important role in fostering pro-environmental behaviours to address the climate crisis.

道德直觉预测气候公域游戏中的亲社会行为

摘要 气候危机和应对气候危机的呼吁通常以道德为框架，但很少有研究测试道德直觉的个体差异是否与可能影响气候公地的亲环境行为相关。在本研究中，我们询问道德基础理论量化的关于伤害（关怀和同情）、公平、群体忠诚、对权威的立场和纯洁的道德直觉是否与亲环境行为相关。参与者玩了 10 轮公共产品游戏，该游戏的框架是开采对气候公域产生负面影响的矿物。我们发现参与者在第一轮游戏中的抽取与忠诚度和权威道德基础呈正相关。游戏所有十轮的平均提取与伤害呈负相关，与忠诚道德基础呈正相关，具有小到中等的影响大小。公平维度仅与第一轮的抽取相关性较弱，与整个游戏的平均抽取无关。无论是第一轮还是平均，纯度维度都与提取无关。这些结果表明，道德直觉等内在因素可能在培养亲环境行为以应对气候危机方面发挥重要作用。无论是第一轮还是平均，纯度维度都与提取无关。这些结果表明，道德直觉等内在因素可能在培养亲环境行为以应对气候危机方面发挥重要作用。无论是第一轮还是平均，纯度维度都与提取无关。这些结果表明，道德直觉等内在因素可能在培养亲环境行为以应对气候危机方面发挥重要作用。
