Science explains intense polarization in American politics

Article Summary

The US political landscape is more polarized than ever, with voters remaining staunchly divided as the 2024 primary season begins. Studies suggest that the nation’s politics are increasingly emotional, with policy preferences often entangled in strong dislike of opposing parties – a phenomenon called “affective polarization.” The tendency to form tightly knit groups for survival is rooted in human evolution, but in the current political climate, this can fuel an irrational contempt for those outside of one’s group. Factors like gerrymandering and the two-party system further contribute to polarization. The rise of social media and the fragmentation of the media landscape have made it easier for people to form echo chambers that intensify their beliefs, leading to increasing partisan division even in personal relationships.


Trump Supporters Stand Steadfast Despite Challenges

In Atkinson, N.H., supporters of former president Donald Trump, fresh from his major Iowa victory, braved a snowstorm for the chance to hear their leader speak. Despite logistical issues and a longer than expected wait due to the weather, these loyal members of the “Trump tribe” remained steadfast. They even showed their loyalty by expressing their displeasure towards the news media when asked to do so.

The Polarization of American Politics

This antagonism towards media is only a fragment of a larger political and cultural phenomenon. The United States is more politically divided than ever, with inflammatory rhetoric and rising anger being a common occurrence. As the 2024 primary season commences, voters remain polarized with little movement on either left or right. Social scientists have been actively studying these hardening political divisions, seeing a steady rise in tribalism and a shift towards more emotion-based politics, a phenomenon they term as “affective polarization.”

The Evolutionary Roots of Group Identification

The tendency to form tightly-knit groups is believed to be rooted in evolution. Survival relied on cooperation, and identifying the rivals was crucial for securing scarce resources. In the context of modern-day politics, the two major parties, Democrats and Republicans, are viewed as zero-sum competitors. Human nature may not be the primary cause of polarization, but it can be exploited by cunning political operatives.
