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?

In this episode, we speak with Cory Clark, behavioral scientist and Associate Professor of Psychology at New College of Florida. We discuss her paper, “Taboos and Self-Censorship Among U.S. Psychology Professors," which explores how controversial topics in science are perceived, debated, and sometimes suppressed, and the psychological dynamics of taboo beliefs and self-censorship in academia.

There is no political topic that can get people’s blood boiling quite like partisan gerrymandering. But what do we know about how effective it is and what the data shows about its outcomes?

This week, we're re-releasing our conversation with Princeton political scientist Kosuke Imai about his paper, "Widespread Partisan Gerrymandering Mostly Cancels Nationally, But Reduces Electoral Competition.” He uses a novel methodological approach to try and document the effect of partisan gerrymandering. What he finds is surprising and may lead people who participate in it to re-think whether it’s worth the effort.

What happens when a political party nominates a candidate in its primary who is ideologically extreme? Do donors, especially those outside the party’s base, react — and if so, how? That question is explored in a new paper by Andy Christopher Wayne Myers, Ph.D. Candidate in Political Science at Stanford University. He uncovers how donors respond when a relative “moderate” is replaced by a more extreme nominee and if the force of donors is actually weaker than it once was.

More than 25 percent of countries around the world are currently governed by populists, from Recep Tayyip Erdogan in Turkey, to Nicolás Maduro in Venezuela, and Donald Trump in the United States. Based on these findings, populism is at an all-time high, and taking a significant economic toll, according to a recent paper by Christoph Trebesch and his co-authors.

Trebesch is Professor of Economics at Kiel University. He and his co-authors find that populism leads to slower economic growth, undermines democratic institutions, and can leave the country more vulnerable to future populist governments.

What if most political science studies are too weak to find the effects they’re looking for? In this episode, we dig into a new paper by Vincent Arel-Bundock and colleagues that reveals a striking truth: quantitative political science is greatly underpowered. With thousands of tests analyzed, the authors show that many studies have only a one-in-ten chance of detecting real effects — and that even experts vastly overestimate the field’s strength.

Arel-Bundock is Professor of Political Science at the Université de Montréal. In his new paper, he concludes that methodologists greatly overestimate the statistical power of political science research.

For decades, free trade was treated as an unquestioned good—an engine of prosperity and cooperation. But today, leaders from Washington to Beijing are rethinking trade as something very different: a tool of power.

In this episode, we dive into new research with Harvard’s David Yang that asks: how do trade relationships actually give countries leverage over one another? Why might exports matter more than imports when it comes to power? And how do tariffs, subsidies, and industrial policy reshape not just economies, but the global order itself?

We explore what this means for U.S.–China rivalry, Trump’s tariffs, Germany’s dependence on Russian oil, and why trade power may sometimes matter as much as military power.
