Learn More About My Research


I am a fifth-year Ph.D. student in Political Science at Washington University in St. Louis. I study comparative politics and political behavior. Specifically, I am interested in authoritarian politics, government censorship, propaganda, popular protest, and political repression. Methodologically, I use a wide range of research methods, including formal modeling, randomized experiments, and computational methods (text-as-data and audio-as-data). I have regional expertise in East and Southeast Asia.

My dissertation, Normalization: Explaining Public Support for Government Censorship in Authoritarian Regimes, proposes a new way of understanding censorship and authoritarian control. My study highlights the normalization of coercive policies, such as censorship, as a powerful channel through which authoritarian regimes achieve social control. Apart from censorship, I also have projects in progress concerning propaganda, emotions, and public opinion toward the use of force in China and other authoritarian regimes.

In 2021, I received my A.M. degree in Political Science from Washington University in St. Louis. Prior to joining Washington University, I received an LL.B. degree in Law from Renmin University of China in 2018.

[1] Yang, Tony Zirui. "Normalization of Censorship: Evidence from China" Under Review

[SSRN] [Online Appendices]


Previous research claims that public awareness of censorship will lead to backlash against the regime. However, surveys consistently find that Chinese citizens are apathetic toward or even supportive of government censorship. To explain this puzzle, I argue that citizens are subject to a process of normalization. Specifically, individuals become desensitized to censorship when the range of censored content expands beyond politically threatening topics like government criticism and collective action to other seemingly harmless non-political issues. Using a dataset of 15,872 censored articles on WeChat and an original survey experiment in China, I show that (1) a majority of censored articles are unrelated to politically threatening topics, and (2) respondents exposed to the censorship of both political and non-political content display less backlash toward the regime and its censorship policy than those who were only exposed to political censorship. My findings highlight how normalization of repressive policies contributes to authoritarian control.

Contrary to the conventional top-down view of government censorship, ordinary citizens in authoritarian regimes frequently participate in censorship by reporting online content. This study theorizes a bottom-up perspective of censorship in authoritarian regimes and analyzes its prevalence and consequences on public opinion toward censorship in the case of China. I argue that public participation increases support for censorship by diminishing the government's responsibility and strengthening citizens' perceived empowerment. Using an original survey in China, I show that more than half of the respondents have flagged content online and such participation is positively correlated with support for government censorship. I further conducted an experiment embedded in custom-engineered, simulated social media pages. Consistent with my theory, respondents that are encouraged to report simulated posts display significantly higher support for government censorship. My study highlights the role of ordinary citizens in facilitating authoritarian control and the normalization of repressive policies such as censorship.

[3] Chen, Haohan, Yiqiang Wang, and Tony Zirui Yang. "Listen to the Party! Propaganda Delivery in Authoritarian Regimes"


Which components of propaganda do authoritarian regimes deliver with higher emotional intensity? In this study, we posit that delivery is a unique dimension of authoritarian propaganda, and analyzing delivery allows us to gauge the priority of regime propaganda strategies. Specifically, a higher vocal pitch of propagandists reflects higher emotional intensity associated with the propaganda materials, which implies issue importance. Focusing on the case of China, we collect three years of original audio recordings from Xinwen Lianbo, a flagship propaganda program, and construct audio-based measures of emotional intensity using vocal pitch. We then use structural topic models and word-embedding methods to identify different propaganda topics and keywords. We find that topics related to Xi Jinping and coercive apparatus are delivered with higher emotional intensity. Our study sheds light on the coercive nature of China's propaganda strategies and extends the audio-as-date method to the Chinese language and the study of authoritarian politics.
