Compulsory Voting Spurs Blank Ballots: Why the Disengaged Do Distrust

Who casts blank or spoiled ballots under mandatory voting? This study identifies politically unengaged, distrusting, disaffected individuals as driving increased invalid balloting in countries with compulsory voting. A key finding reveals that these voters turn out primarily to avoid sanctions for abstention rather than participate meaningfully. Why It Matters: The results suggest voter engagement campaigns might help mitigate this problem.

📊 Data & Methods

Survey data from several American democracies, many of which compel electoral participation, were analyzed at the individual level to examine how compulsory voting influences invalid balloting rates.

🔍 Key Findings

• Higher rates of blank/spoiled ballots occur in countries with compulsory voting systems.
• These higher rates are linked to voters who lack political knowledge or interest (the politically unengaged).
• Voters who distrust the system and feel disaffected also disproportionately use invalid options.

💡 Significance

This research demonstrates how mandatory voting can interact unexpectedly with public sentiment.
