Yet, in general, political knowledge is quite low among the public. Moreover it is distributed unequally among social segments. Therefore the legitimacy of representative democracy is challenged. The German “Wahl-O-Mat” aims at informing the electorate on party positions and at fostering “correct voting”. During the campaign for the Bundestag election 2013 the “Wahl-O-Mat” was used more than 10 million times.In this article we ask in how far the “Wahl-O-Mat” contributes to voters’ political knowledge on parties’ positions on selected political issues. Our analysis is based on an online pre-experimental design conducted two weeks before the election. The main results show that using the “Wahl-O-Mat” increases knowledge on party positions, but only to a small degree. Besides improvements of information levels, the number of “don’t know”-answers also rises. The degree to which individuals are able to learn depends strongly on pre-existing knowledge levels. The latter in turn are determined by motivation and resources.}, journal = {ZPol Zeitschrift für Politikwissenschaft}, pages = {389--426}, author = {Westle, Bettina and Begemann, Christian and Rütter, Astrid}, volume = {24}, number = {4} }
