Welcome back! On Jiang Zemin’s 90th birthday, I’m happy to share another Jiang-Wallace interview that might help improve understanding of China and Chinese politics. I had the pleasure of talking with Junyan Jiang, who is finishing his PhD in Political Science at the University of Chicago and starting as a post-doc at University of Pennsylvania, about his recently published paper, “Lying or Believing? Measuring Preference Falsification From a Political Purge in China” in Comparative Political Studies and co-authored with Dali Yang also at UofC. The paper navigates a difficult task: it measures citizens in a dictatorship falsifying their preferences about the government when interacting with survey researchers.
