The prevailing logic in today’s political world is that polarization is worsening because people live in media echo chambers where they are only exposed to outlets that mirror their views. People who live in echo chambers come to distrust any opinions outside their bubbles, especially when they're not exposed to conflicting information. This creates a scenario where the person becomes increasingly entrenched in their worldview.

One would assume that after a person becomes fully entrenched in an echo chamber, they have little chance of changing their views. However, a new working paper by researchers at Stanford and Yale universities has found that when people are removed from their bubbles, there’s a chance they’ll change their minds.

David Broockman of Stanford and Joshua Kalla of Yale conducted a study in 2022 where they paid regular Fox News viewers $15 an hour to watch CNN for around seven hours a week for a month. The researchers then surveyed them about their political beliefs and knowledge of current events.

The study is titled “The manifold effects of partisan media on viewers’ beliefs and attitudes: A field experiment with Fox News viewers.” It was conducted in fall 2020, during the height of the COVID-19 pandemic and the lead-up to the presidential election.

When the participants were polled, researchers found that they were five percentage points more likely to believe that people suffer from long COVID, 6 points more likely to think that other countries did a better job of controlling the virus, and 7 points more likely to support voting by mail.

“CNN provided extensive coverage of COVID-19, which included information about the severity of the COVID-19 crisis and poor aspects of Trump’s performance handling COVID-19. Fox News covered COVID-19 much less,” said the study.

After Fox viewers switched to CNN, their opinions on the social justice protests happening at the time changed. The switchers were 10 points less likely to think that Biden supporters were happy when police got shot and 13 points less likely to believe that if Biden gets elected, “we’ll see many more police get shot by Black Lives Matter activists.”

Many of the participants also realized that when it came to Trump, they weren’t getting the whole story. After switching to a steady diet of CNN they were less likely to agree that “if Donald Trump did something bad, Fox News would discuss it.”

“Despite regular Fox viewers being largely strong partisans, we found manifold effects of changing the slant of their media diets on their factual beliefs, attitudes, perceptions of issues’ importance, and overall political views,” the authors of the study said.

The study shows that Fox News isn’t just a media outlet that affirms its viewers' worldviews; it also feeds them a distorted version of reality that pushes them toward more extreme opinions. The good news is that some of these people can be changed when exposed to better information. It should also be noted that Fox News viewers aren’t the only ones living in information bubbles and that there are plenty of ideological traps that ensnare people on the left as well.

“Partisan media aren’t just putting a thumb on the scale for their side,” Brockman said. “They’re also hiding information that voters need to hold politicians accountable. That’s not just good for their side and bad for the other side — it’s bad for democracy, and for all of us.”

Two months after the study, it was found that the Fox News viewers reverted to their opinions before their exposure to CNN. Still, Brockman believes that the study offers some hope in a time of deep political polarization. “Even among the most orthodox partisans and partisan media viewers,” he said, according to Berkeley, “those who receive a sustained diet of information that helps them see the bigger picture actually are open-minded enough to understand that their side isn’t doing a perfect job, either.”

The study should give everyone hope that all is not lost and that America’s political divide may not be impossible to bridge.
