尽管对人为气候变化的科学警报越来越多,世界没有走上解决危机的轨道。不作为的部分原因可能是对气候变化的怀疑态度和对维持现状的人们对环境政策的抵制(即,保守派右派)。因此,需要实际的干预措施。在目前的研究计划中,我们测试了一种源自系统合理性理论的实验操作,在该理论中,亲环境倡议被定为爱国和维持美国“生活方式”所必需的。“在一个大的,具有全国代表性的美国样本,我们发现,系统认可的变革干预成功地增加了自由左派和保守右派对气候变化的信念;对环保政策的支持;以及在社交媒体上分享气候信息的意愿。在涉及63个国家的汇总分析中,类似的信息是有效的,尽管总体效应大小很小。在国家一级进行的更细粒度的探索性分析显示,尽管干预措施在某些国家取得了一定的成功(例如,巴西,法国,以色列),它在其他国家适得其反(德国,比利时,俄罗斯)。在三个结果变量中,干预的效果在美国是一致和明显的,支持可以代表社会变革利用系统理由动机的假设。讨论了不同国家一级影响的潜在解释。系统认可的变革干预措施为寻求提高气候意识和行动的决策者和传播者带来了巨大的希望。
Despite growing scientific alarm about anthropogenic climate change, the world is not on track to solve the crisis. Inaction may be partially explained by skepticism about climate change and resistance to proenvironmental policies from people who are motivated to maintain the status quo (i.e., conservative-rightists). Therefore, practical interventions are needed. In the present research program, we tested an experimental manipulation derived from system justification theory in which proenvironmental initiatives were framed as patriotic and necessary to maintain the American \"way of life.\" In a large, nationally representative U.S. sample, we found that the system-sanctioned change intervention successfully increased liberal-leftists\' as well as conservative-rightists\' belief in climate change; support for proenvironmental policies; and willingness to share climate information on social media. Similar messages were effective in an aggregated analysis involving 63 countries, although the overall effect sizes were small. More granular exploratory analyses at the country level revealed that while the intervention was moderately successful in some countries (e.g., Brazil, France, Israel), it backfired in others (Germany, Belgium, Russia). Across the three outcome variables, the effects of the intervention were consistent and pronounced in the United States, in support of the hypothesis that system justification motivation can be harnessed on behalf of social change. Potential explanations for divergent country-level effects are discussed. The system-sanctioned change intervention holds considerable promise for policymakers and communicators seeking to increase climate awareness and action.
