Listening to Outsiders: The Impact of Messenger Nationality on Transnational Persuasion in the United States

Does nationality disadvantage foreign actors when they attempt to persuade the American public? Using data from an online survey experiment administered to a sample of US citizens, we find that the nationality of British and French advocates only reduces persuasiveness among American Republicans with low levels of political awareness. Among American Democrats, credible French or British advocates can be more persuasive than a comparable American source. Overall, foreign messengers from friendly countries are not disadvantaged by nationality, as nationality has low political salience and other domestic characteristics (such as partisanship) dominate subjects' heuristic processing. When a foreign advocate's nationality does play a role, however, it is likely to lead to polarization in domestic audience attitudes.
