Researchers interested in climate change communication have investigated how people respond to messages about it. Through meta-analysis, the current research synthesizes the multitude of experimental studies on this topic to uncover which interventions are most effective at influencing attitudes about climate change. The meta-analysis focuses on experimental studies that included a control condition and measured climate change attitudes among participants in the United States. After a large literature search, 396 effect sizes were retrieved from 76 independent experiments (N = 76,033 participants). Interventions had a small, significant positive effect on attitudes, g = 0.08, 95% CI [0.05, 0.10], 95% prediction interval [-0.04, 0.19], p < .001. Surprisingly, type of intervention was not a statistically significant moderator of this effect, nor was political affiliation. However, type of attitude was a significant moderator: the treatment-control difference in attitudes was smaller for policy support than for belief in climate change, indicating that policy attitudes are more resistant to influence than belief in climate change. Interventions that aimed to induce skepticism (e.g., misinformation) had a significantly stronger average effect on attitudes than did ones that intended to promote belief in climate change, suggesting that belief in climate change is more easily weakened than strengthened.

影响美国对气候变化的态度:系统评价和荟萃分析
对气候变化传播感兴趣的研究人员调查了人们如何回应有关它的信息。通过荟萃分析,当前的研究综合了关于该主题的大量实验研究,以揭示哪些干预措施最有效地影响对气候变化的态度。荟萃分析侧重于实验研究,其中包括控制条件和美国参与者对气候变化态度的测量。经过大量文献搜索,从 76 个独立实验(N = 76,033 名参与者)中检索到 396 个效应量。干预对态度有小的、显着的积极影响,g = 0.08, 95% CI [0.05, 0.10], 95% 预测区间 [-0.04, 0.19], p < .001。令人惊讶的是,干预类型并不是这种影响的统计学显着调节因素,政治派别也不是。然而,态度类型是一个显着的调节因素:政策支持的态度差异小于气候变化信念,表明政策态度比气候变化信念更能抵抗影响。旨在引起怀疑(例如,错误信息)的干预对态度的平均影响比旨在促进对气候变化的信念的平均影响要大得多,这表明对气候变化的信念更容易削弱而不是加强。
