polarization
Definition
Polarization refers to the widening divide between opposing political groups, marked by stronger ingroup identity, colder attitudes toward the outgroup, and increasingly divergent emotional and psychological responses to shared political events. In the United States, this trend has intensified over the past decade, with both politicians and the public leaning more heavily on partisan identity. Research conducted during the early months of President Trump's second term found that this divide carried measurable consequences for subjective well-being, with Democrats and Republicans reporting consistently different levels of life satisfaction and happiness across five weekly waves. The gap was large and statistically reliable, with effect sizes exceeding half a standard deviation, and was associated with differing levels of support for government actions rather than partisan affiliation alone.

Polarization and Subjective Well-being
Political polarization is associated with decreased well-being, and during periods of democratic backsliding this association becomes particularly pronounced. In a longitudinal study spanning February through March 2025, Democrats consistently reported lower life satisfaction and happiness than Republicans across all five measurement waves, with group differences remaining significant after controlling for demographics and subjective socioeconomic status. Support for government actions explained a substantial portion of these differences, with backing the administration's actions correlating with higher well-being and support for oppositional actions correlating with lower well-being.

Polarization and Partisan Affiliation
Partisan affiliation is both a product of political polarization and a predictor of well-being outcomes during politically charged periods. During the early months of President Trump's second term, Republicans were more supportive of administration actions while Democrats favored oppositional actions, a division consistent with the broader partisan divide. Even after controlling for political affiliation and demographics, the association between support for government actions and well-being remained significant in most cases, indicating that the psychological consequences of polarization extend beyond group membership itself.
