野火在美国西部造成越来越大的威胁。我们在西科罗拉多进行了一项在线选择实验，以评估社会互动如何通过两种不同的途径影响野火缓解决策：风险相互依赖（邻居的条件影响感知的野火风险）和社会规范（邻居的行为影响适当的缓解选择的感知）。与关键的观测研究相比，我们发现，当参与者有更多的邻居稀疏植被时，他们不太可能选择缓解。这种效应通过风险相互依赖途径发挥作用：邻近财产上的稀疏植被降低了参与者的野火风险感知，似乎被视为自己缓解行动的替代品。在这种情况下，邻居们都是无名无姓的，社会规范并不能抵消这种负面影响。为了使这一实验结果与观察性研究相一致，我们讨论了风险相互依赖性和社会规范如何受到地理和社会背景的影响，并强调这些见解如何为未来的研究和政策行动提供信息。
Wildfire presents a growing threat across the American West. We conducted an online choice experiment in Western Colorado to assess how social interactions affect wildfire mitigation decisions through two distinct pathways: risk interdependency (neighbors' conditions affect perceived wildfire risk) and social norms (neighbors' actions affect perceptions of appropriate mitigation choices). In contrast to key observational studies, we find that participants are less likely to choose to mitigate when they have more neighbors with sparse vegetation. This effect operates through the risk interdependency pathway: sparse vegetation on neighboring properties lowers participants' wildfire risk perceptions and appears to be viewed as a substitute for one's own mitigation actions. In this context, where neighbors are nameless and faceless, social norms do not counteract this negative effect. To reconcile this experimental result with observational studies, we discuss how both risk interdependency and social norms are influenced by geographical and social contexts and highlight how these insights can inform future research and policy action.
