Conscientiousness of representatives and agreement with their party positions

Abstract

ABSTRACT Party unity is an important feature in contemporary democracies. Ideological loyalty, disciplinary measures implemented by party leaders and homogeneity of preferences among elected representatives lead them to act in unison. This study focuses on the last mechanism and assesses under which conditions party representatives agree on policy positions. It argues that the personality trait of conscientiousness is linked to how a representative agrees with her party’s position and that this relationship is moderated by her knowledge of dissent between party voters and representatives. This study use data from a comparative survey conducted among 866 representatives in Belgium, Canada, Germany and Switzerland, and among the party constituencies in the four countries. Results show that conscientious representatives are more likely to differ significantly from the position of their party peers if they spend more time on constituency work and if their voters’ preferences are not congruent with those of their fellow representatives.
