Opinion Science

Rhia Catapano studies what happens when people think of an opinion in terms of what they support versus what they oppose. It turns out that this simple difference carries important implications. Even if we're talking about the same basic opinion, something shifts when it's about support than opposition. In our conversation, Rhia shares her findings and what it means for people who want to communicate more effectively.
At the top of the show, I discuss Issue 1 in Ohio from 2023. Most of the background details for that were drawn from this NYT article.

Demi Oba is an Assistant Professor of Marketing at Harvard Business School. He studies the nature of communication. In our conversation, Demi shares some recent research on the different types of "hedges" people make when expressing uncertainty in a claim. These types of uncertainty matter for how persuasive a person can be. In fact, sometimes, being the right kind of uncertain can be more influential than expressing confidence.

Jae-Hee Jung is an assistant professor at Rice University, where she studies party politics, political behavior, and political psychology in Western democracies. Her research focuses on the strategic use of moral rhetoric (i.e., appeals to fundamental notions of right and wrong) and how it shapes political competition and voter psychology.
We talk about her work analyzing political manifestos, the psychological mechanisms like pride that mobilize a party's base, and the surprising finding that inclusive moral messaging can actually build sympathy across the aisle without causing a partisan backlash. Along the way, we see how framing policies around core principles rather than simple costs and benefits changes the way voters connect with political parties over the long haul.
Dr. Jung's new book is Shared Morals: The Role of Moral Rhetoric in Party Politics.

Elizabeth Dunn and Jiaying Zhao are professors at the University of British Columbia, where they study social psychology and climate behavioral science, respectively. Together, they explore the intersection of human happiness and environmental action, challenging the traditional "guilt and shame" narratives that dominate climate communication. We talk about their new book: Leave the Lights On: How Joyful Decisions Can Save Our Species, which explores how you can address climate change by taking actions that make you feel happy. We see how reframing environmental choices around joy can create a more effective, contagious movement for behavior change.

Yamil Velez is an assistant professor of political science at Columbia University, where he studies what makes political opinions hard to shift. He’s been using innovative new methods to test important ideas about how people arrive at their views and what it takes to change them. We talk about the relationship between beliefs and opinions, why correcting misinformation doesn’t necessarily move opinions, and what happens when persuasive messages are tailored to the specific reasons people hold their views. 
Yamil shares his work using large language models to generate personalized arguments, showing that people will update their beliefs pretty readily—but only some of those belief changes actually translate into attitude change. Along the way, we explore what this means for persuasion, polarization, and the future of using AI to study (and maybe influence) public opinion.
