Engaging politically polarized publics surrounding climate science is a vital element in the effort to enact climate mitigation policy. Science communication experts have identified several models of public engagement with science, including the deficit, dialogue, participation, and lay expertise model. Existing research suggests that the deficit model in particular is a largely ineffective model of engagement for controversial science like climate change. There is very little research, however, regarding the engagement preferences of political groups, or how those preferences differ. This study assesses preferences for climate change engagement in the state of Oregon in the United States and examines the relationship between those preferences and epistemic beliefs about climate science. Overall, we find that liberals are significantly more likely than moderates or conservatives to view climate science as certain and simple and to rely on expert knowledge more than their own direct experience. By contrast, conservatives are significantly more likely than liberals or moderates to view climate science as uncertain and complex and to rely on their own direct experience over the knowledge of content experts. We also find that perceived certainty and simplicity are positive predictors of a preference for the deficit model of science communication. Implications for public engagement with climate change and suggestions for future research are discussed.

围绕气候科学让政治两极分化的公众参与是制定减缓气候变化政策的重要因素。科学传播专家已经确定了几种公众参与科学的模式，包括赤字、对话、参与和非专业知识模式。现有研究表明，特别是赤字模型对于气候变化等有争议的科学来说是一种基本上无效的参与模型。然而，关于政治团体的参与偏好或这些偏好有何不同的研究很少。本研究评估了美国俄勒冈州对气候变化参与的偏好，并检验了这些偏好与气候科学认知信念之间的关系。全面的，我们发现自由主义者比温和派或保守派更有可能将气候科学视为确定和简单的，并且更多地依赖专家知识而不是他们自己的直接经验。相比之下，保守派比自由派或温和派更有可能将气候科学视为不确定和复杂的，并依赖于他们自己的直接经验而不是内容专家的知识。我们还发现，感知的确定性和简单性是偏好科学传播赤字模型的积极预测因素。讨论了公众参与气候变化的影响以及对未来研究的建议。保守派比自由派或温和派更有可能将气候科学视为不确定和复杂的，并依靠他们自己的直接经验而不是内容专家的知识。我们还发现，感知的确定性和简单性是偏好科学传播赤字模型的积极预测因素。讨论了公众参与气候变化的影响以及对未来研究的建议。保守派比自由派或温和派更有可能将气候科学视为不确定和复杂的，并依靠他们自己的直接经验而不是内容专家的知识。我们还发现，感知的确定性和简单性是偏好科学传播赤字模型的积极预测因素。讨论了公众参与气候变化的影响以及对未来研究的建议。
