Americans are perhaps more polarized today than at any time since the Civil War. This idea has become ingrained in contemporary American discourse, popping up with increasing frequency in media coverage, in public opinion studies, and in research about how social media and its “filter bubbles” are driving polarization.
People tend to think of the arena of politics as being driven by human decision and emotions, and therefore unpredictable. But network scientists like Boleslaw Szymanski, a computer science professor at Rensselaer Polytechnic Institute, have found that the country’s political…
Bitter fighting continues in the aftermath of the 2020 presidential election, even as President-elect Joe Biden urged unity in his victory speech Saturday night. Michael Macy, professor of sociology and information science at Cornell University and director of the Social…
Study by UC’s New Electorate Project documents a growing divide on preferences for absentee ballots. Before the pandemic, there wasn’t any difference in the rates at which Democratic and Republican voters actually cast their ballots by mail or in-person. That may change now.

New research provides insight into how housing prices and neighborhood values have become polarized in some urban areas, with the rich getting richer and the poor becoming poorer.
In this week’s Chaos, researchers use a theoretical model to examine what effect extreme views have on making the entire system more polarized. The group’s network-based model extends a popular approach for studying opinion dynamics, called the Cobb model, and is based on the hypothesis that those with opinions farther from the middle of a political spectrum are also less influenced by others, a trait known to social scientists as “rigidity of the extreme.”
Activity from phony Twitter accounts established by the Russian Internet Research Agency between 2015 and 2017 may have contributed to politicizing Americans’ position on the nature and efficacy of vaccines, a health care topic which has not historically fallen along party lines, according to new research published in the American Journal of Public Health.
In collaboration with Marshall Space Flight Center (MSFC), the Center for Space Plasma and Aeronomic Research (CSPAR) at The University of Alabama in Huntsville (UAH) has a significant role in LEAP – the LargE Area burst Polarimeter – a mission that is one of four proposals approved by NASA for further review.
