Barking at the Jersey: Why Political Hatred is More Like Sports Than Civil War

Pundits warn that intense partisan hatred between left and right is on the verge of tearing modern democracies apart; an 18,000-person study across nine nations proved that voters’ political anger behaves like toxic sports fandom that vanishes when actual practical laws are on the table. Published in the European Journal of Political Research, this comparative study shows that citizens can despise opposing political parties while remaining fully willing to compromise on real economic solutions.

Barking at the Jersey: Why Political Hatred is More Like Sports Than Civil War

In modern political debate, conventional wisdom warns that democracies are collapsing under "affective polarization"—the bitter emotional hatred that opposing party voters feel toward one another. Commentators fear that voters hate their opponents so much that bipartisan compromise has become mathematically impossible.

Political scientists tested eighteen thousand voters across nine democracies, including the US, UK, Germany, and Canada. They discovered that partisan anger operates like aggressive sports team fandom: while voters enthusiastically boo and insult the opposing team’s jersey, their hatred evaporates when presented with blind policy choices—agreeing on tax cuts, healthcare funding, and infrastructure.

The study reveals that political anger is mostly theatrical cheerleading rather than deep ideological war. By proving that voters are far more pragmatic than cable news suggests, by reassuring democratic stability, and by guiding constructive political dialogue, comparative political science strengthens democracy.

Title

The (alleged) consequences of affective polarization: A survey experiment in nine democracies

Abstract

Affective polarization (or antipathy between supporters of opposing political camps) is considered a threat to societal cohesion and democratic stability worldwide. However, causal evidence of its impact remains scarce, especially outside the United States. Our study examines the individual-level consequences of affective polarization by manipulating it in a survey experiment in nine countries (Brazil, France, Germany, Italy, Poland, Spain, Sweden, the United Kingdom, and the United States; N ≈ 18,000) and subsequently assessing the downstream consequences for social avoidance and discrimination of opponents, support for aggression, aversion to political compromise, democratic norms, democratic dissatisfaction, and political engagement. Our intervention successfully reduced participants’ affective polarization in six out of nine countries. In turn, this was associated with significant improvement in interpersonal relations and (in contrast to recent US studies) support for democratic norms. Importantly, the impact varied between societies, suggesting that the consequences of affective polarization may be more context-dependent than previously understood.
