Why This Research Matters
Disadvantaged ethnic minorities often need to persuade majority members that they face unfair treatment to win public support and policy change. Peter Thisted Dinesen, Clara Vandeweerdt, and Kim Mannemar Sønderskov investigate which kinds of evidence—statistical reports or personal stories, and whether the evidence is unambiguous or ambiguous—are most effective at changing majority perceptions and behavior.
How Evidence Was Compared
The authors organize evidence along two dimensions: character (statistical versus personal) and ambiguity (manifest versus ambiguous). Combining those dimensions produces four real-world treatments based on audit-study results and personal accounts. The research tests a set of pre-registered hypotheses about how these different types of evidence affect majority awareness of ethnic minority discrimination and downstream actions.
What the Authors Did
Two pre-registered survey experiments were conducted in Denmark. Respondents were exposed to one of the four real-evidence treatments, and measures captured (a) awareness that ethnic minorities experience discrimination, (b) support for anti-discrimination policies, and (c) willingness to donate to an immigrant NGO.
Key Findings
- Manifest evidence—both an audit study showing explicit discrimination and a personal story that clearly documents discriminatory treatment—was the most effective at increasing majority members' awareness that ethnic minorities face discrimination.
- A personal story with manifest discrimination also produced behavioral and policy effects: it raised support for anti-discrimination policies and increased donations to an immigrant NGO.
Broader Implications
These results suggest that clarity of harm matters: unambiguous demonstrations of discrimination are more persuasive than ambiguous signals, and personal narratives that explicitly show unfair treatment can both shift beliefs and spur action. The findings inform advocacy strategies and the study of public opinion by showing how the form and clarity of evidence shape majority responses to minority claims.
