Revisiting the Effects of Case Reports in the News

Synthesizing several theories about the likely impact of case reports in the news, we propose that the impact of featuring identified victims in a news story is contingent on the degree of similarity between the audience member and the identified victims. We execute a population-based survey experiment involving immigration policy to examine our theory. Our results suggest that featuring specific, identified victims in a news story will promote more supportive policy opinions than otherwise identical stories about unidentified victims, but only when the victim is highly similar to the audience member. Conversely, case reports featuring identified people who are dissimilar to the audience member will decrease the extent to which the story encourages victim-supportive policy attitudes. Overall, our experimental findings shed light on the conditions under which the inclusion of case reports increases versus decreases the policy relevance of news stories. Our findings also help explain previous inconsistencies in findings about the impact of case reports. Additional analyses allow us to speculate as to the reasons for the differential direction of effects.
