Researchers have linked a variety of emotions including anger, hatred, fear and humiliation to intergroup conflict attitudes. National humiliation has particularly come under scrutiny because of its influence on China's and Russia's foreign policies. Do emotional expressions of humiliation cause advocacy of hostile foreign policy positions and shape foreign policy debates? Further, how do emotions spread socially to become politically relevant? To answer these questions, Dr Masterson draws on group-based emotions theory and appraisal theory from psychology to construct a theory of political emotional contagion. To evaluate this theory, he uses supervised machine learning to measure the narratives of national humiliation and foreign policy positions in a large (more than 1.6 billion posts), nationally representative data set of Chinese social media posts. Dr Masterson finds that posts invoking narratives of national humiliation are more likely to support using military force, maintaining disputed territorial claims and raising trade barriers. He also finds evidence of emotional contagion as users sharing national humiliation narratives causes their followers to become more likely both to share such narratives in the future and to express support for hostile policy positions.
