ABSTRACT Voting Advice Applications (VAAs) – also known as Voting Engagement Applications – are online tools which inform users about their proximity to party positions before elections by indicating which parties are closest to the policy preferences of the individual voters. Referring to the theory of cognitive dissonance, this article examines the impact of using a VAA on voting behaviour by looking at the effect mechanisms. For the empirical analyses, we draw on data of a two-wave panel study we conducted before the European Elections 2014, thereby focusing on the German VAA – the Wahl-O-Mat. The findings show that irritation emerges if the preferred party is not positioned at the top of the VAA result list. In turn, a strong irritation can lead to a change in vote choice.
