Joon H. Chung is an MA student majoring in political science at Columbia University. He studies international security through the lens of psychology and is broadly interested in foreign policy decision making, crisis bargaining, diplomacy & signaling, democracy promotion, and international relations theory. His methodological focus is on causal inference using experimental and statistical methods. Chung's current researches try to resolve puzzles like, why leaders engage in diplomacy even if rationalists argue that it is cheap, how a diplomatic failure could lead structural uncertainties to war, how the sense of reality affects the leaders' prospect of winning in the crisis bargaining, and how it is possible to generalize results from experiments with convenience samples.
Prior to Columbia, Chung received BA, 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).
