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.
