How do elite cues shape public opinion? We assess two ways in which such cues may be influential: by changing citizens’ factual beliefs about the world (the “factual channel”) or by triggering a moral reevaluation (the “moral channel”). We study this issue in the context of the papal encyclical on climate change, in which Pope Francis attempted to persuade Catholics that there is a scientific consensus around climate change and that protecting the environment is a moral and religious obligation. Exploiting panel data from the United States before and after the encyclical, we find that both mechanisms played a role: Catholics who regularly attended church became disproportionately more likely to believe both that global warming was happening and that climate change was a religious issue. The pope's influence on Catholic policy preferences, however, operated only through the factual channel.
