An uninformed electorate: identity-motivated elaboration, partisan cues, and learning

摘要

A deliberative democracy is reliant on an informed electorate discussing issues and presenting persuasive arguments. Individuals acquire information from exposure to political messages. Partisan cues, however, undermine learning outcomes. The current study experimentally examines the social cognitive processes that underlie this learning process. Integrating the social identity theory, elaboration likelihood model, and the theory of motivated reasoning to construct the theoretical concept of identity-motivated elaboration, the results indicate that partisan social identities motivate biased processing of new information, which subsequently influences the valence of elaboration. Positively and negatively valenced elaboration are situated as mediating variables in the structural model, which predicts learning from a persuasive political message. The current study extends the partisan social identity hypothesis to the elaborative and learning outcomes of political messages.
