Description of VAAs

• Provides voting advice by matching voters' policy views with candidates' positions.

• Voters express their views on issues that reflect the most important dimensions of political competition.

• A formula calculates proximity of voters’ positions to the positions of the candidates

• The output of the application is a ranked list of candidates according to calculated voter/candidate proximities.

Impact on voting choice

• Depends on whether the VAA user had chosen a candidate before using the application.

• Undecided > VAA can help them learn the positions of candidates and choose the most suitable to represent them.

• Decided > two possible outcomes: – i) identical voting recommendation > strengthen the

user's intent to vote for the preselected candidate – ii) VAA does not propose the same candidate > the

VAA recommendation could undermine user's initial selection, and if the influence is strong enough, it can lead to change of voter's position.

Implications for parties

• New, minor parties– opportunity to disseminate their positions– overcome limited access to traditional media – VAA outcome is based only on proximities – equal opportunities

• Both new and older, well know parties– reach a particular subset of the electorate with

limited political interest

Conclusions

• VAAs inform citizens about the positions of candidates and parties on important issues of electoral competition

• VAAs help people shape their electoral choice• VAAs can help undecided voters to choose candidates• May even influence decided voters by:

– proposing the same candidate and affirming their initial choice or– undermining their confidence in their initial selection by

proposing a different candidate.

• Indications that VAAs can lead to a reduction of abstention rates (needs further research)
