When confronted with experimental treatments, synthetic respondents accurately guess the hypothesis under investigation at high rates (A), provide responses that are consistent with the detected hypothesis, but do so imperfectly (B and C), and bias the treatment effect in the predicted direction (D).

AI presents a fundamental threat to our ability to use polls to assess public opinion. Bad actors who are able to infiltrate panels can flip close election polls for less than the cost of a Starbucks coffee. Models will also infer and confirm hypotheses in experiments. Current quality checks fail

Very few Americans support actual political violence. Many more support intimidation. Almost no one thinks it’s appropriate to kill your political opponents, but many more would dox them.

Research Shows There Are No Easy Fixes to Political Hatred

A non-partisan team has found reducing polarization and “partisan animosity” is remarkably difficult. “Without systemic change, America’s political divisions will only deepen,” says Annenberg associate professor Yphtach Lelkes.

Preprint: Levels of Office and Voter Accountability for Democratic Norm Violations

⚠️New paper fothcoming in POQ! ⚠️
With @marcjacob.bsky.social and @seanjwestwood.bsky.social, we worried about norm-violating local politicians rising to higher office. We tested when voters defect from such politicians in local, state and federal races.

Research Shows There Are No Easy Fixes to Political Hatred | Faculty of Arts and Sciences Study finds that interventions to reduce partisan animosity have fleeting effects.

“This isn’t a problem that can be fixed at the grassroots level alone.” Research from @prl.bsky.social, co-led by professor @seanjwestwood.bsky.social, finds most attempts to reduce partisan animosity are modest and fleeting. Structural reform and civic education are key to lasting depolarization.

"We are collecting data continuously so we have a baseline understanding of what level of support for political violence exists in our country.” Professor @seanjwestwood.bsky.social, director of @prl.bsky.social, discusses political violence in the U.S. on @theguardian.com’s Science Weekly podcast.

10 Political Violence Experts on What Comes Next for America Can America escape the spiral of political violence after Charlie Kirk’s killing?

“The core problem is not a widespread desire for violence, but a profound misperception of the other side.” Professor @seanjwestwood.bsky.social, director of the @prl.bsky.social, reflects on a seeming cycle of political violence in America, via @politico.com.

‘Fascist’ Ended Up on an Assassin’s Bullet. It Has Become Common Currency in Politics. Democrats and Republicans alike call each other fascist. That is unlikely to stop after the killing of Charlie Kirk.

A bullet casing found after the killing of Charlie Kirk had an inscription reading, “Hey fascist! Catch!” Charges of fascism have become a fixture of the nation’s political dialogue.

Democracy Fellows Explore How to Bridge the Partisan Divide | Dartmouth

PRL brought 10 Dartmouth undergraduates to DC in June to introduce them to people and orgs across the political spectrum working for democracy. Many thanks to those who hosted us!!

📢 The final piece of my dissertation is out in @polbehavior.bsky.social! Does being an ideologue matter for political disagreement—beyond how many issues are involved? It does, shaping both animosity and how people engage. 🧵https://doi.org/10.1007/s11109-025-10049-z

Partisanship swamps other factors in determining support for recent policies, even when they seemingly implicate traditional support for free expression.

Data from @thefireorg.bsky.social's April 2025 National Speech Index, part of @prl.bsky.social's fantastic national panel.

Negative partisanship is a helluva drug:

Up until a few months ago, liberal and conservative Americans held pretty much the same views on free trade.

Now, not so much…

More partisan atttitudinal asymmetries -- since the presidential election, Democrats' national pride/trust in government has collapsed, while Republicans' values have only edged upwards.

Yphtach Lelkes Awarded 2025 Andrew Carnegie Fellowship

Prof. @ylelkes.bsky.social has been awarded a 2025 Andrew Carnegie Fellowship. Lelkes, co-director of @prl.bsky.social, will study how political hostility is shaped in an overloaded information environment.

Dr. Sean Westwood studies how political hatred takes root—and why Americans may still be more committed to democracy than we think.

A powerful look at polarization, resilience, and the future of civic life.
