Is political polarization worse than it's been in the past?
Short answer: It depends on what you mean by “polarization” and which era you compare to.
In the United States today:
•Congress/elite polarization: By roll‑call voting and ideology scores, the two parties are farther apart and overlap less than at any time since the early 20th century. In that sense, it’s near a modern high compared with roughly 1910–present.
•Public ideology: Most Americans haven’t moved dramatically to policy “extremes.” Instead, they’ve sorted—liberals are more reliably Democratic and conservatives more reliably Republican—so cross‑party coalitions that were common in the mid‑20th century are rarer.
•Affective polarization: Negative feelings toward the other party and “us vs. them” social bias have risen steadily since the late 1970s and are at record highs in modern survey data.
•Conflict/violence: Despite grave episodes (e.g., 1960s political violence; the January 6, 2021 attack), today is not on the level of the 1850s–1860s sectional crisis and Civil War era for overt, society‑wide violent conflict.
Historical context
•Compared with the depolarized mid‑20th century (roughly the 1940s–1970s), today is clearly more polarized.
•Compared with America’s most fractured periods (the 1790s’ partisan press wars, the 1850s before the Civil War, parts of Reconstruction, and some late‑19th‑century fights), today is less violent but more cleanly sorted by party, ideology, geography, and identity than most of the last 100 years.
Why it looks worse now
•Party realignments since the 1960s, nationalized media and social media, primary elections that reward ideological loyalty, gerrymandering in some states, and fewer cross‑cutting social ties all amplify partisan distance and distrust.
Bottom line: Versus most of the 20th century, polarization is worse today in the U.S.—especially among political elites and in how partisans feel about each other. Versus the nation’s most perilous 19th‑century episodes, it’s less openly violent, though the alignment of identities and institutions makes politics feel more zero‑sum.
If you had a different country in mind—or want data visuals (e.g., congressional scores or sentiment trends)—say which, and I can tailor it.
