Emotional Appeals, Climate Change, and Young Adults: A Direct Replication of Skurka et al. (2018)

There is much need to verify the robustness of published findings in the field of communication—particularly regarding the effects of persuasive emotional appeals about social issues. To this end, we present the results from a preregistered, direct replication of C. Skurka, J. Niederdeppe, R. Romero-Canyas, and D. Acup (2018). The original study found that a threat appeal about climate change can increase risk perception and activism intentions and that a humor appeal can also increase activism intentions with a large sample of young adults. Using the same stimuli, measures, and experimental design with a similar sample, we fail to replicate these main effects. We do, however, replicate age as a moderator of humor’s effect on perceived risk, such that the humor appeal only persuaded emerging adults (ages 18–21.9). We consider several explanations for our discrepant findings, including the challenges (and opportunities) that persuasion researchers must navigate when communicating about rapidly evolving social issues.
