Is academic dishonesty connected to political power in China? That question is explored in a new paper from Shaoda Wang, Assistant Professor at the University of Chicago Harris School of Public Policy. Wang and his co-authors explore how plagiarism detection in graduate dissertations is connected to patterns of cheating in career paths and institutional behavior. What lessons might this hold for politics, meritocracy, and institutional performance elsewhere?

In this episode, we sit down with Stanford political scientist Andy Hall and PhD candidate Graham Straus to unpack their new paper, “How Accurately Did Claude Code Replicate and Extend a Published Political Science Paper?” — an empirical audit of what happens when an AI agent is asked to replicate and extend a real research project.

Last January, Andy asked Claude Code to generate an extension of an existing empirical political science paper in under an hour. The results were surprising: Claude correctly replicated the original estimates exactly and collected new data with very high accuracy. But did Claude make mistakes? Straus independently audited Claude’s work to see how accurate, reliable, and scientifically sound it really was.

Do members of Congress vote differently when they are worried about winning their party’s primary election? On today's episode, Ethan and Wioletta interview Anthony about his forthcoming paper, “Do Primary Elections Exacerbate Congressional Polarization?,” which is forthcoming from the Journal of Politics.

Using detailed voting data and the natural variation in primary election timing across states, Anthony and his co-author, Shu Fu, show that primaries play a surprisingly small role in pushing lawmakers to the ideological extremes—accounting for only about 1% of congressional polarization.

Do politicians really understand what drives voters—or are they relying on flawed assumptions that could shape democracy in troubling ways?

As we take some time off for the holidays, we wanted to re-share our episode with University of Calgary political scientist Jack Lucas, whose paper “Politicians’ Theories of Voting Behavior,” reveals striking gaps between how politicians perceive voters and how voters see themselves. While politicians often hold a cynical, “democratic realist” view of voters, citizens are far more optimistic about their own behavior. But who’s right—and does it even matter?
