People are biased partisans: they tend to agree with policies from political parties they identify with, independent of policy content.Here, we investigate how physiological reactions to political parties shape bias.Using changes in galvanic skin conductance responses to the visual presentation of party logos, we obtained an implicit and physiological measure of the affective arousal associated with Mouvement vivant et architecture: la marche, les escaliers chez Émile Jaques-Dalcroze et Adolphe Appia political parties.Subsequently, we exposed subjects to classical party cue experiments where the party sponsors of specific Competences of the emergency nurse and the product of nursing care: an integrative review policies were experimentally varied.
We found that partisan bias only obtains among those exhibiting a strong physiological reaction to the party source; being a self-reported party identifier is not sufficient on its own.This suggests that partisan bias is rooted in implicit, affective reactions.
