Voting Aid Applications and the Effect of Statement Selection

Abstract

Voting Aid Applications (VAA) helping voters make their decision at the ballots have become more popular throughout Western Europe. They typically consist of a number of statements that are used to match voters with parties. Drawing on a large-scale simulation of 500,000 different configurations of 36 statements and on a random sample of Belgian voters, the paper shows that many of these combinations produce diverging information for the participants. The study establishes that the specific selection of statements has a considerable impact on the 'voting advice' that is produced: some configurations favour certain parties, other configurations benefit other parties.
