What's the point of voting advice applications? Competing perspectives on democracy and citizenship

Voting advice applications (VAAs) are interactive online tools designed to assist voters by improving the basis on which they decide how to vote. Current VAAs typically aim to do so by matching users' policy-preferences with the positions of parties or candidates. But this 'matching model' depends crucially on implicit, contestable presuppositions about the proper functioning of the electoral process and about the forms of competence required for good citizenship-presuppositions associated with the social choice conception of democracy. This paper aims to make those presuppositions explicit and to contrast them with two possible alternative perspectives on VAAs, associated with deliberative and agonistic conceptions of democracy and citizenship.
