Putting Within-Country Political Differences in (Global) Perspective
Open accessAbstract
The current political discourse in the United States focuses on extreme political polarization as a contributor to ills ranging from government shutdowns to awkward family holidays. And indeed, a large body of research has documented differences between liberals and conservatives-primarily focused on Republicans and Democrats in the United States. We combine large international surveys and more fine-grained surveys of United States citizens to compare differences in opinion between Republicans and Democrats to the full range of world opinion on moral issues (N = 37,653 in 39 countries) and issues of free speech (N = 40,786 in 38 countries). When viewed in the full distribution, polarization between Democrats and Republicans appears relatively small, even on divisive issues such as abortion, sexual preference, and freedom of religious speech. The average Democrat-Republic overlap is greater than 70% of the country pair overlaps across eight moral issues, meaning that 70% of the country pairs are more dissimilar from each other than Democrats and Republicans are dissimilar; similarly, the average Democrat-Republic overlap is greater than 79% of the country pair overlaps across five freedom of speech issues. These results suggest that cross-cultural comparisons are useful for putting differences between political partisans within the same country in context.

Levels of polarization in the USA are smaller than (or similar to) levels observed in other countries.
“For example, there is evidence that ideological, issue and affective polarization have increased rapidly in the USA in the past few decades339,340, but it is also true that levels of polarization in the USA are smaller than (or similar to) levels observed in other countries65,341.”

The Abstract reports that Democrat–Republican differences on moral and free-speech issues are relatively small compared with differences between pairs of countries. The Discussion clarifies that the study compares political groups within the United States with other countries; it does not establish that polarization within other countries is as high as, or higher than, polarization within the United States.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
