Affective Polarization and Ideological Sorting: A Reciprocal, Albeit Weak, Relationship

Lelkes, Yphtach·2018·The Forum

Abstract

American partisans are far more hostile towards out-party members than they were 40 years ago. While this phenomenon, often called affective polarization, is well-documented, political scientists disagree on its cause. One group of scholars believes that affective polarization is driven by processes related to social identity theory. In particular, cross-cutting identities have declined in America, and toxic political communication continuously primes partisan identities and resentment. Recently, several scholars have pointed to another phenomenon as the root cause of affective polarization: partisan sorting, i.e. the alignment of partisan identities with ideologically consistent issue positions. I review evidence in favor of each claim, and provide additional evidence that affective polarization has increased about as much among those who are not sorted as among those who are sorted. Furthermore, while sorting is only related to affective polarization among the most politically knowledgeable, affective polarization has increased across all levels of political knowledge. Finally, affective polarization may also increase sorting, further complicating any clear cut causal relationship.

  • Over the past 40 years, affective polarization as measured by feeling thermometer differences increased by about the same amount among those who held the most ideologically consistent issue positions as among those who held the least ideologically consistent issue positions.

    “Furthermore, over the past 40 years, affective polarization-as measured by feeling thermometer differences-increased by about the same amount among those who held the most ideologically consistent issue positions as among those who held the least ideologically consistent issue positions (Lelkes 2018).”
  • The relationship between ideological polarization, sorting, and affective polarization is weak, with sorting accounting for only about 5% of the variance in affective polarization.

    “the relationship is weak, with sorting accounting for only about 5% of the variance in affective polarization (Lelkes 2018, Mason 2018a).”
  • Longitudinal research demonstrated that ideological consistency at time 1 predicted affective polarization at time 2, and affective polarization at time 1 predicted ideological consistency at time 2, all other things being equal.

    “Moreover, longitudinal research demonstrated that ideological consistency at time 1 predicted affective polarization at time 2, and affective polarization at time 1 predicted ideological consistency at time 2, all other things being equal82,87.”

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.
