On a crisp June morning, Cornell economists set out to crack the echo chamber that has long dominated American political discourse.

The experiment, published on June 8, 2026 in the Economic Journal under the title Breaking Echo Chambers: An Experimental Study on the Willingness to Listen to Opposite Views, was written by Michèle Belot of Cornell’s Department of Economics and Guglielmo Briscese, formerly of the University of Chicago. The authors surveyed roughly 2,500 U.S. adults, a sample designed to mirror the national population.

Respondents first rated their own positions on three divisive issues—abortion, gun laws, and immigration—using a 1‑to‑10 scale. Afterward, they were offered the chance to listen to up to three short audio clips. Each clip featured a person who held an opposing view on one of the three topics. The recordings were drawn from a separate survey and were presented as optional, mirroring the way most people encounter news in everyday life. According to the authors, about 70 % of participants listened to all three clips, 18 % listened to two, and the remaining 12 % chose to skip them.

The study also tested whether highlighting common ground would affect listening behavior or opinion change. In one treatment group, participants were told that the speaker in the clip agreed with them on selected statements from the United Nations Universal Declaration of Human Rights—such as the right to peaceful assembly. In a second group, the speaker was described as agreeing with basic etiquette rules—saying “please” and “thank you,” being on time, and waiting one’s turn. A control group received no such framing.

Belot and Briscese found that the presence of shared values did not make people more likely to listen. However, compared with the control group, participants who learned that the speaker shared common values or etiquette were more likely to adjust their own positions after listening. Roughly 10 % of respondents moved toward a less extreme score on abortion and immigration, but not on gun laws, which the authors note was the least divisive of the three issues.

"They become a little bit closer to the middle," Belot said in a statement. "Views become a little bit less polarized."

The authors argue that the willingness to listen may stem from curiosity and a desire to clarify one’s own thinking—an impulse that also drives people to re‑watch presidential debates with friends or family. While listening alone does not change the information people receive, it can help them process that information more thoughtfully.

The study builds on the contact hypothesis, a decades‑old social‑psychology theory that suggests that interaction between groups can reduce prejudice when common goals are emphasized. Prior research on echo chambers has focused on social‑media exposure and the interpretation of facts, whereas this experiment examined voluntary engagement in a setting that mimics everyday media consumption.

The authors note that their findings could inform existing efforts to reduce polarization. They cite nonprofits such as Braver Angels and StoryCorp’s One Small Step, which already seek to create spaces where people with opposing views can discuss issues. "There’s a lot more we can do to emphasize things we have in common, even if we disagree strongly on a topic," Belot said.

The study is the first large‑scale experiment to show that a majority of Americans will voluntarily listen to opposing viewpoints and that shared values can modestly shift opinions. No policy recommendations or legislative actions have yet followed the publication, and the authors emphasize that further research is needed to understand how these findings translate into real‑world political engagement.

The research adds nuance to the narrative that echo chambers are inevitable. While the study does not eliminate the possibility of selective exposure, it suggests that the capacity to listen—and the presence of common ground—may be a small but meaningful lever for reducing polarization.
