Partisanship as Social Identity; Implications for the Study of Party Polarization

Shanto Iyengar / Masha Krupenkin
Published Online: 2018-06-09 | DOI: https://doi.org/10.1515/for-2018-0003


Partisanship continues to divide Americans. Using data from the American National Election Study, as well as implicit attitude tests, we argue that Americans’ partisan identity has become highly salient. Partisans have become more negative towards the opposing party on both explicit and implicit measures, and these biases spill over into their everyday decisions. Partisanship has become one of Americans’ most salient social identities.
