门户信念模型描述了一个态度变化的过程，其中人们对某个问题的科学共识的看法发生变化，导致他们的态度发生后续变化，进而预测对公共行动支持的变化。在当前的研究中，我们首次提出了 GBM 的大规模验证性复制。具体来说，我们对美国人口的全国配额样本（N = 6,301）进行了共识消息实验。结果支持了 GBM 的中介假设：实验引起的科学共识的变化导致了对气候变化的认知（信念）和情感（担忧）判断的后续变化，而这反过来又与支持公共行动的变化相关。科学共识信息也对公众行动的支持产生了直接影响。我们进一步发现了政治意识形态和先前态度之间的相互作用，使得保守派和气候变化怀疑论者更有可能更新他们的信念以达成共识。我们讨论了该模型的理论和实践意义，包括为什么传达科学共识有助于减少出于政治动机的推理。
The Gateway Belief Model describes a process of attitudinal change where a shift in people's perception of the scientific consensus on an issue leads to subsequent changes in their attitudes which in turn predict changes in support for public action. In the current study, we present the first large-scale confirmatory replication of the GBM. Specifically, we conducted a consensus message experiment on a national quota sample of the US population (N = 6,301). Results support the mediational hypotheses of the GBM: an experimentally induced change in perceived scientific consensus causes subsequent changes in cognitive (belief) and affective (worry) judgments about climate change, which in turn are associated with changes in support for public action. The scientific consensus message also had a direct effect on support for public action. We further found an interaction with both political ideology and prior attitudes such that conservatives and climate change disbelievers were more likely to update their beliefs toward the consensus. We discuss the model's theoretical and practical implications, including why conveying scientific consensus can help reduce politically motivated reasoning.
