Who Should Call for Advocacies? The Influence of Rights Advocates on the Public's Attitude Toward Immigrants’ Voting Rights in Japan

Abstract

Native allies are critical to the success of immigrants’ social movements in East Asian countries because of their relatively small number. However, it remains unclear whether advocacy messages from natives or from immigrants are more effective in changing natives’ attitudes toward supporting immigrant-oriented policies. We hypothesize, from the perspective of social identity theory, that the persuasiveness of a message varies, depending on the identity of the group sending the message—that is, whether it is an in-group or an out-group. To test this hypothesis, we conducted a survey experiment using the case of granting local voting rights to immigrants in Japan. We found that support for granting local voting rights to immigrants does not decrease when the Japanese hear advocacy messages from the Japanese, however, it does decrease when they hear messages from Korean immigrants who stand to benefit from the granting of local suffrage. These results suggest that natives’ advocacy messages may increase support for immigrants.
