Notably absent from much of the literature, however, were words that could suggest a “tribal” political identity, said Diamond.

“In the briefing materials and as much as possible, in the discussion, we very consciously avoided the following four words: Democrat, Republican, Trump, Obama. We tried to get people just to talk about the issues without stereotyping themselves or one another,” he said.

Citizen delegates stayed in the same group throughout the weekend, which allowed them to build personal connections with one another. For some, it was the first time they interacted extensively with people far removed from their own daily lives. Conservative professionals talked with homeless people and low-income people engaged with corporate executives, Diamond described.

“People began to see one another as human beings,” Diamond said. “They got to know one another and they began to develop something that is so rare in our hyper-polarized society: empathy.”

As people learned how others would be personally affected by a proposed policy change, attitudes shifted.

Before participants took part in America in One Room, they were asked to rate their support (or opposition) for some 49 policy proposals they would be discussing. The researchers found extreme partisan-based polarization between Democrats and Republicans on 26 of the proposals. But after a weekend of deliberation, the two parties moved closer on 22 out of the 26 proposals and in 19 of those, movements were significant, Fishkin and Diamond reported in a paper presented at the Sept. 2020 meetings of the American Political Science Association.

In addition to surveying attendees, the researchers also administered similar questionnaires to another 844 American voters who stayed home and did not participate in the deliberative polling experiment. This control group showed little change in their opinion, the researchers reported.

One of the most polarizing issues was the deportation of undocumented immigrants. Before deliberation, 79 percent of Republicans supported the proposal “undocumented immigrants should be forced to return to their home countries before applying to legally come back to the U.S. to live and work permanently.” After deliberation, the number was halved: 40 percent said they supported the policy.

While no undocumented immigrants participated at the America in One Room event, their stories were told by their family members or acquaintances who were in attendance. These perspectives ultimately persuaded some Republicans who learned about the plight of refugees and asylum seekers to hold a more sympathetic view of immigrants, the researchers report.

Republicans were not the only ones who changed their mind; Democrats were also swayed. For example, 70 percent of Democrats supported the policy that “people should be automatically enrolled in a more generous version of Medicare.” But after deliberation, it dropped to 56 percent.

“If you have a moderated discussion with diverse others, you open up to people from different socio-demographic backgrounds and different points of view, you learn to listen to them as well as speak to them. If the discussions are in-depth enough, people will depolarize,” said Fishkin, noting that this effect was not the scholars’ intention when they developed the exercise. “We did not design the deliberative poll with the aim of depolarizing, although it has turned out to have that effect.”

The researchers also found that people came to like each other more. After deliberation, dislike between the two parties diminished: Democrats’ “feeling thermometer” ratings of Republicans rose 13 points with deliberation. Republicans’ ratings of Democrats went up 14 points.

Bringing deliberative democracy to scale

Fishkin recognizes that engaging the public with Deliberative Polling requires organization and infrastructure; one of its main criticisms is that it is costly and timely to administer.

That’s why Fishkin and Alice Siu, the associate director at CDD, are working to scale the method more broadly. For example, they have collaborated with Ashish Goel, a professor of management science and engineering, and his team to build a digital platform for facilitating discussion. In lieu of a human moderator, a chatbot regulates the conversation. Through online automation like this, there is no limit to how many Americans can get involved – but only if they are willing, Diamond emphasized. “You need intentionality,” he said.

Another way Fishkin and Siu are spreading their approach is through schools. They’ve developed a toolkit to help teachers incorporate deliberative democracy into civic studies curriculum that includes research assignments and discussion exercises that aim to simulate an environment similar to that in America One Room where students can discuss issues with one another with mutual respect.

“It’s actually a more effective form of civic education we believe than conventional civic education because anything very active is better than something passive and,” Fishkin said, pointing to evidence from one study and another nationwide experiment with over 300 high schoolers that tested the Stanford Online Deliberation Platform.

What deliberative democracy reveals

Fishkin and Diamond contend that deliberative democracy does more than just uncover what people believe – it also reveals why people think the way they do. Understanding what motivates people’s beliefs and assumptions can be a useful tool to inform and advance public policy, the scholars believe.

“Knowing what arguments resonated and the reasoning behind certain arguments can be very helpful to policymakers in understanding if they want to bring the people along on an issue,” Diamond said.

The scholars hope that the public, including policymakers, will take notice of what their approach reveals about their fellow Americans.

“One of the most important misconceptions about political polarization in the United States is the assumption that people and society are hopelessly divided and that the root cause of our political paralysis in Washington is that we all hate one another and across party lines and have these unassailable divides,” said Diamond.

Diamond and Fishkin say it is critical to find opportunities to incorporate deliberation into politics and the political system, such as changing the incentive structure of primary voting. Typically, only highly-motivated voters – who tend to be more extreme in their views – turn out to vote in a primary election. This leads to more extreme candidates being nominated and a feeling among elected officials that they shouldn’t deliberate because they can’t afford to politically, Fishkin said.

“We have to institutionalize ways which will get the public voice on a more regular basis of what they would think. That, I think, is the way of ending the uncivil war that we’ve been finding ourselves in lately,” Fishkin added. “There is value and even joy in listening to one another and thinking about arguments and life perspectives that we haven’t thought about before.”
