Joon H. Chung is an M.A. student majoring in political science at Columbia University. He studies international security through the lens of psychology and is broadly interested in threat perception, foreign policy public opinion, and presidency & foreign policy. His methodological focus is on causal inference based on laboratory, field, and survey experiments. Chung's current researches try to resolve puzzles like, why leaders engage in diplomacy even if rationalists argue that it is cheap, how public statements about personal diplomacy influence the citizens' foreign policy attitude, how presidents manipulate public opinion on foreign policy through framing and priming, and how it is possible to generalize results from experiments with convenience samples.
Prior to Columbia, Chung received B.A., highest honors (top 1%), in political science and philosophy from Yonsei University, South Korea. He also edited and wrote chapters of a book, Taming Democracy with Liberalism: The Politics In and Out of Liberal Democracy (Paju: Dongmyeongsa, 2019; in Korean).
