This chapter focuses on the behavioral implications of popular conceptions of democracy, that is, the attitude-to-behavior connections and in particular, conventional and unconventional political participation. The chapter shows that overall, compared to their fellow citizens emphasizing the instrumental values of democracy, people embracing the procedural understanding of democracy are significantly more likely to cast ballots, help with electoral campaigns, contact political and government agencies or agents, join a demonstration, march in a protest, or use violence for a political cause. Meanwhile, this impact varies significantly, depending on the features of the regime in a society: it is much stronger in authoritarian regimes than in democracies. In some cases, the impact even reverses as we move from autocracies to democracies. The chapter argues that such patterns are primarily driven by the expressive values served by political participation, which people embracing the procedural conception of democracy are more sensitive to.
