Voteswiper VAA Survey Data for 2025 German Federal Election

Sebastian Jäckle's dataset contains follow-up survey data from users of the Voteswiper Voting Advice Application during the 2025 German federal election campaign. It analyzes the alignment between VAA results and users' prior voting intentions, as well as correlations with subsequent short-term voting intentions. The data reveals differences in VAA effects across social groups and party preferences.

Use Cases

• Analyze the alignment between VAA results and users' prior voting intentions for parties like the far-right Alternative for Germany.
• Investigate correlations between VAA matches and subsequent short-term voting intentions across different social groups.
• Assess the frequency of VAA matches for fringe parties versus centrist parties among survey respondents.
• Examine how VAA results influence intended vote choices for populist or fringe parties.

Strengths

• Data is directly linked to a specific political event, the 2025 German federal election.
• Focuses on a contemporary research topic regarding the polarizing effects of Voting Advice Applications.
• Survey design captures both prior preferences and short-term voting intentions post-VAA use.

Limitations

• The specific sample size (row count) and number of survey variables (columns) are unknown.
• Data is limited to users of a single VAA (Voteswiper) and may not represent all German voters.
• Findings are based on a follow-up survey, which may introduce non-response or recall bias.
