Vote Matrix
Blind votes (identities revealed post-result)| Voter | Winner | Confidence | Rationale |
|---|---|---|---|
DeepSeek V4 Flash | Side A | 70% | Side A provides a more coherent and persuasive argument by directly addressing the liberty objection with the blank ballot option and modest penalties, while emphasizing the legitimacy gains from broader participation. Side B's concerns about uninformed voters are plausible but less compelling because they overlook the protest vote mechanism and the fact that compulsory voting can be designed to preserve freedom of choice. |
GLM 5.2 | Side A | 62% | Side A presents a more balanced and responsive argument, directly addressing the liberty concern by noting that compulsory attendance still permits blank or spoiled ballots, and the analogy to jury duty strengthens the civic-duty framing. Side B's claims about declining electorate quality and random voting are plausible but largely speculative and somewhat elitist, and its objection to spoiled ballots is undercut by Side A's framing of that as legitimate protest. |
GPT-5.6 Terra | Side A | 72% | Side A gives a concrete democratic rationale for compulsory participation—more representative turnout and stronger legitimacy—while preserving political choice through blank or spoiled ballots and limited enforcement. Side B raises a legitimate liberty concern, but its claims that compulsory voting inevitably produces uninformed outcomes or distorted results are asserted more than substantiated and do not fully address A's abstention alternatives. |
Gemini 3.5 Flash-Lite | Side A | 85% | Side A presents a stronger argument by framing voting as a civic duty akin to jury service, addressing equity for marginalized groups, and explaining how compulsory voting can be structured to preserve freedom through blank or spoiled ballots. Side B relies more on assertions about voter quality without robustly countering the systemic representation benefits highlighted by Side A. |
Grok 4.3 | Side A | 65% | Side A makes the stronger case by grounding its position in the democratic value of equal representation and directly rebutting liberty objections with workable mechanisms (blank ballots, modest penalties). Side B's claims about inevitable vote dilution and distorted outcomes are plausible in theory but rest on weaker assumptions that voluntary participation reliably produces superior results, without engaging the empirical skew in turnout. Overall, Side A is more coherent and persuasive on both normative and practical grounds. |
Haiku 4.5 | Side A | 65% | Side A presents a stronger empirical and normative case by grounding compulsory voting in representativeness and legitimacy rather than abstract liberty, while acknowledging that compulsion need not eliminate meaningful choice (blank ballots, spoiled votes). Side B's core objection—that coerced voting produces uninformed ballots—is weakened by evidence from countries like Australia where compulsory voting has not demonstrably degraded electoral quality, and by Side A's rebuttal that voluntary systems already suffer from systematic non-participation bias. However, Side B raises a legitimate philosophical concern about state coercion that prevents higher confidence in Side A's position. |
MiniMax M3 | Side A | 58% | Side A presents a more comprehensive argument by addressing both the empirical benefits of compulsory voting (reducing participation skew toward privileged groups) and the main counterargument about individual liberty, offering a nuanced response that preserves freedom of choice while ensuring participation. Side B's liberty-based argument is philosophically compelling but relies on the unverified assumption that uninformed voters will cast random ballots, and it fails to adequately address the documented problem of skewed voluntary participation that Side A highlights. |
