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.
