Most of us study international relations to help improve the state of our world. Yet, political scientists and policy makers increasingly operate in two completely different spheres. The purpose of this seminar is to help bridge this gap: to develop a social science-based toolkit for solving complex global problems. By the end of the quarter, you will be deeply familiar with the most important explanations of international relations, be comfortable reading contemporary political-scientific literature, and instinctively assess world events and identify solutions by leveraging theory and evidence. Prerequisites: POLISCI 101.
