Is political polarization worse than it's been in the past?
Leans yes
Short answer: In the United States, polarization is higher than it was a few decades ago, but it isn’t the worst in all of history. Globally, the picture is mixed—some democracies are more polarized, others are not.
What “worse” means depends on the type of polarization:
•Elite/party polarization (in Congress): Very high. Voting patterns show Democrats and Republicans are farther apart than at any time since the late 19th century. The mid-20th century’s cross–party overlap (Southern Democrats, liberal Republicans) has largely disappeared.
•Mass ideological polarization (policy views among citizens): Real but more modest. Average Americans haven’t moved to extremes across the board, but they’re more consistently liberal or conservative than in the 1990s, with less cross-pressured “middle.”
•Affective polarization (how much partisans dislike the other side): Very high and rising since the 1970s. Large majorities view the other party very negatively, up from small shares in the 1990s. Out-party “feeling thermometer” ratings have dropped markedly.
•Social sorting: Identities like religion, race, education, and urban–rural residence now line up more neatly with party, intensifying us-vs-them dynamics. Ticket-splitting and split control of offices are rarer.
Compared with the past:
•Versus mid-late 20th century (1950s–1980s): Today is clearly more polarized across parties, media, and social identities.
•Versus the 19th century and the Civil War era: That period featured deeper ideological divides and much greater violence; by those standards, today’s polarization is serious but not unprecedented.
•Versus the 1960s–70s: Those decades were turbulent and violent in society, but the parties themselves were less ideologically sorted than today.
Why it’s risen (US evidence):
•Party realignment by race, region, religion, and education since the 1960s.
•Nationalization of politics and decline of local cross-party coalitions.
•Media fragmentation and algorithmic information environments (effects vary but can heighten animus and misperceptions).
•Geographic sorting and safe districts; gerrymandering contributes at the margins but isn’t the main cause.
•Rising economic inequality and zero-sum perceptions.
•Primary elections and donor incentives that reward ideologically consistent, combative candidates.
Consequences:
•More legislative gridlock and brinkmanship.
•Norm erosion and greater tolerance for undemocratic actions by co-partisans.
•Stronger negative partisanship, which boosts turnout but can reduce compromise.
•Misperceptions of the other side’s views, fueling cycles of escalation.
Outside the US:
•Increased polarization is evident in several places (e.g., UK post‑Brexit, Poland, Turkey, India, Brazil), but the levels, causes, and forms vary. Many multiparty parliamentary systems experience fragmentation rather than strict two-camp polarization.
If you have a specific country or type of polarization in mind, I can tailor the answer and include a few up-to-date numbers.
