This chapter focuses on electoral ergonomics, defined as the interface between every aspect of electoral organization and the psychology of the voters. It argues that every small detail in the organization of the vote (electoral ergonomics) matters not only mechanically, but also because of the way it may trigger different psychological mechanisms and emotional reactions, and that as a result, the ergonomic interface will have different effects on different types of voter, such as ‘referees’ or ‘supporters’. Indeed, electoral ergonomics affects the way citizens experience the vote, their attitudes, their likeliness to vote in elections, and their actual electoral choice. The chapter then unpacks the theoretical and empirical logic behind the influence of electoral ergonomics, both in general and through specific case studies. These case studies include the impact of the use of remote voting on electoral experience in the general population, its influence on the electoral choice of young voters, and the effect of ballot-paper design (including paper vs electronic ballots) on the electoral experience.
