Mass polarization: Manifestations and measurements
Open accessAbstract
The debate on mass polarization is itself polarized. Some argue that the United States is in the midst of a culture war; others argue that the claims are exaggerated. As polarization is a multifaceted concept, both sides can be correct. I review four distinct manifestations of polarization that have appeared in the public opinion literature—ideological consistency, ideological divergence, perceived polarization, and affective polarization—and discuss ways in which each has been measured. Then, using longitudinal data from the American National Election Studies (ANES), I update past analyses in order to more clearly show the ways in which Americans have or have not polarized: Americans at the mass level have not diverged, nor have they become more consistent ideologically, but partisans have; perceptions of polarization have increased, but this change is driven by partisans, who increasingly dislike one another.

Conceptual proliferation and inconsistency in polarization research have resulted in significant confusion in public discourse and academia.
“Given that distinct manifestations of polarization exhibit different patterns and induce distinct, often opposite causal mechanisms, this conceptual proliferation and inconsistency have resulted in significant confusion both in public discourse and academia (Fiorina & Abrams, 2008;Lelkes, 2016).”

The literature on mass political polarization in the USA has yielded mixed findings about whether ordinary citizens are deeply divided, whether polarization threatens democratic functioning, and the nature of the threat.
“The body of literature on mass political polarization in the USA has yielded mixed findings: ordinary citizens are deeply divided9,31,35,41–49 or they are not10,29,36,50–54; polarization poses a huge threat to democratic functioning3,11,55, is not a problem at all13,56–58 or the nature of the threat is ambiguous7,59,60.”

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.
