From Politico, a report on another James Fishkin deliberative experiments, this one centered on Pennsylvania:

Voters in one of the most divided states in the country moved closer together on immigration, climate change and voter ID requirements after spending just a few days together.

A diverse set of nearly 200 Pennsylvanians from the state’s big cities, far-flung towns and upscale suburbs found common ground on those and a number of other hot-button topics after meeting in a hotel in downtown Philadelphia last month as part of an audacious experiment: If people got offline and actually talked face-to-face, would they become less polarized?…

Here’s how the experiment known as “America in One Room: Pennsylvania” worked: Over the course of four days, voters broke into groups of a dozen or so people to discuss a wide range of policy proposals with a moderator who helped keep the peace. The voters were selected to represent the state’s electorate demographically, politically and geographically. They heard from former Secretary of State Hillary Clinton, a 30-year-old Republican state lawmaker and advocacy group leaders across the political spectrum. And throughout the event, they took opinion surveys, the results of which were shared with POLITICO ahead of their official release.

Support for a national proposal to hand out more visas to so-called low-skilled workers doubled from only 25 percent of participants at the beginning of the study to 50 percent by the end of deliberations. The number of voters favoring a plan to work with other nations to adopt net-zero greenhouse gas emission policies rose from 42 to 55 percent after they exchanged views.

Pennsylvanians came together on conservative ideas, too. Voter ID requirements went from winning over 68 percent of voters to 73 percent — and became backed by a majority of Democrats. Six in 10 voters initially championed free college tuition at public colleges, but support dropped to 46 percent by the end of the event.

The findings underscore the extent to which social media, geographic sorting and partisan echo chambers often fuel partisanship in the U.S. — and point to potential fixes….

The organizers of the experiment said they are working to make the process available to larger groups of people, including through the use of artificial intelligence. Ultimately, they hope to bring it to millions.

They have also been teaming up with elected officials to try to show that their so-called deliberative polling process can be utilized to craft policy — and make the difference that Berkowitz wants. The speaker of the Pennsylvania state House, Democrat Joanna McClinton, attended the event and said that she plans to use the results to help influence voting rights and election administration legislation she has introduced.
