Affective and cognitive underpinnings of moral condemnation when news of transgressions goes viral.

When news of a transgression goes viral, people hear about it repeatedly from different news sources and individuals. How does this repeated exposure affect moral judgments of the transgression? We test a new theoretical model proposing that moral condemnation is influenced by competing affective and cognitive processes. Repeated exposure to the same information about a transgression dampens people's emotional responses, which can reduce moral condemnation (an affective-desensitization process). However, repeated exposure from multiple sources also signals that the transgression is receiving widespread negative attention, which can increase moral condemnation (a cognitive infamy-inference process). These processes' net effect will depend on how strongly repetition dampens affect versus signals infamy. Five preregistered experiments (N = 3,939) test our model. Participants rated corporate transgressions to which they had or had not been repeatedly exposed from three sources (news outlets or individuals). Experiments 1 and 2 measured affective reactions, infamy inferences, and moral judgments, finding mediational support for our model. In Experiment 2 and two supplemental experiments, repetition reduced moral condemnation, suggesting that affective desensitization was the dominant process. Experiment 3 was designed to strengthen the infamy process by highlighting over a million negative reactions to each repeatedly seen transgression; consistent with our model, repetition no longer reduced moral condemnation but continued to dull affective reactions, suggesting that affective-desensitization and infamy-inference processes offset one another. By documenting these countervailing processes, our research deepens understanding of when, why, and how viral transgressions may impact public opinion and moral outrage.
