This resource list contains HxA tools, blog posts, and podcast episodes on the topic of political polarization. In addition, we are also sharing a curated TED talk playlist that you may find helpful. We encourage you to share these materials with friends and family and use them in your classes and on your campuses to generate thoughtful, nuanced conversation about the issue.

Political polarization – the vast and growing gap between ideological groups like Republicans and Democrats – has become a defining feature of modern American life. As the Pew Research Center put it, “Americans have rarely been as polarized as they are today.”

Polarization is affecting Americans on both sides of the political aisle. Pew’s research surrounding the 2020 election shows that “a month before the election, roughly eight-in-ten registered voters in both camps said their differences with the other side were about core American values, and roughly nine-in-ten – again in both camps – worried that a victory by the other would lead to ‘lasting harm’ to the United States.”

While many surveys confirm these findings, there is hope: As partisan as this election was, Pew also found that “overwhelming majorities of both Trump (86%) and Biden (89%) supporters surveyed this fall said that their preferred candidate, if elected, should focus on addressing the needs of all Americans, ‘even if it means disappointing some of his supporters.’”

We hope these materials will lead to deeper understanding and spark conversation about the state of political polarization today.
