The Power of Partisanship

Dyck and Pearson-Merkowitz show how partisanship influences the electorate's support for democratic norms, willingness to engage in risk related to financial and healthcare decisions, interracial interactions, and previously non-political decisions like what we like to eat for dinner. Partisanship prevents people from learning from their interactions with friends or the realities of their neighborhoods, and even makes them oblivious to their own economic hardship. The intensity and pervasiveness of partisanship in politics today has resulted in "political knowledge" becoming an endogenous feature of strong partisanship and a poor proxy for anything but partisan behavior. Dyck and Pearson-Merkowitz present evidence that pure independents are, in fact, very responsive to information because they are not biased by partisan elite cues and important and relevant political information is often local, contextual, and personal. Drawing on a series of original surveys and experiments conducted between 2014 and 2020, Dyck and Pearson-Merkowitz show how the dominance of partisanship as a decision cue has fundamentally transformed our understanding of both political and non-political behavior.
