Mean scores for perceived extent of harm in Studies 1, 2, and 3.
Perceived extent of harm was manipulated as intended in Study 1 (left panel), Study 2 (middle panel), and Study 3 (right panel). Participants in the harm responsible and harm not responsible conditions perceived outgroup members as experiencing significantly more harm than did participants in the no harm condition. Note: Error bars represent ±1 SE. *** denotes p < .001; NS denotes non-significant.

Results of Study 3: Testing for infrahumanization following harm.
The three regression models with emotion humanness as the predictor and emotion typicality for outgroup members (residents of Lagos) as the outcome are displayed. The small negative relationship between these variables did not differ between the three conditions. Note: Grey shading around the slope represents 95% CI.

Results of Study 2.
Mean emotion attributions by condition, emotion humanness, and emotion valence are displayed. We found no evidence that inducing a sense of collective responsibility for the harm experienced by textile workers leads participants to infrahumanize them. Converging with the results of Study 1, participants seemed to rate outgroup members as experiencing negative emotions more strongly when harm against them was made salient. Note: Error bars represent ±1 SE. Shared = emotions shared with other animals. *** denotes p < .001; * denotes p < .05; NS denotes non-significant.

Results of Study 1.
Mean emotion attributions by harm condition, emotion humanness, and emotion valence in Study 1 are shown. We observed no evidence that collective responsibility for harm induced infrahumanization of the outgroup. Instead, residents of Lagos were thought to experience negative emotions to a greater extent and positive emotions to a lesser extent when harm to them was made salient. Note: Error bars represent ±1 SE. Shared = emotions shared with other animals. *** denotes p < .001; NS denotes non-significant.
