What the study found
The study found that exposure to voting advice applications (VAAs, online tools that compare voters’ views with party positions) did not improve party position knowledge in the same way for all respondents. A youth-oriented VAA improved young people’s ability to identify party positions correctly, but a generic VAA did not show a significant learning effect.
Why the authors say this matters
The authors conclude that their findings provide rare causal evidence that VAAs can affect party position knowledge. They also say the results highlight the importance of tailoring such tools to specific audiences.
What the researchers tested
The researchers ran a large-scale experiment in Flanders, Belgium, with respondents aged 16–30. Participants were randomly assigned to a control group or to one of two real-world VAAs: De Stemtest, a generic version for the general electorate, and De Jongerenstemtest, a version designed for younger citizens. They analyzed the results using multilevel logistic regression models.
What worked and what didn't
The youth-oriented VAA significantly improved respondents’ ability to identify party positions correctly. The generic VAA produced no significant learning effect. The study also found that learning effects did not vary systematically across parties or between mainstream and niche parties.
What to keep in mind
The abstract describes one experiment among Belgian respondents aged 16–30, so the findings are limited to that sample and setting. The available summary does not describe additional limitations beyond this scope.
