Vote Matrix
Blind votes (identities revealed post-result)| Voter | Winner | Confidence | Rationale |
|---|---|---|---|
GLM 5.2 | Side A | 60% | Side A presents a more compelling case by grounding compulsory voting in concrete democratic benefits—broader representativeness, reduced influence of money in mobilization, and a strong civic duty analogy to taxes and jury service. Side B's liberty argument is philosophically sound but relies on somewhat speculative claims about uninformed ballots diluting outcomes, and its alternative solutions, while reasonable, do not fully address the systemic participation gap that Side A identifies. |
GPT-5.6 Luna | Side A | 58% | Side A more directly explains concrete democratic benefits of compulsory voting, including broader representation and reduced reliance on mobilizing narrow partisan bases. Side B raises a strong liberty objection and reasonably notes that abstention can be meaningful, but its claims about compulsory voting producing mainly uninformed or random outcomes are asserted rather than demonstrated. |
GPT-5.6 Terra | Side B | 62% | Side B more directly addresses the core normative conflict: whether democratic participation can be legitimately compelled, emphasizing that abstention can itself be political expression. Side A makes plausible claims about turnout and representation, but overstates that compulsory voting produces active consent or eliminates money’s electoral influence. |
Gemini 3.5 Flash-Lite | Side A | 85% | Side A presents a compelling case by framing voting as an essential civic duty akin to taxes and jury duty, while logically connecting high turnout to broader representation and reduced influence of money in politics. Side B relies heavily on libertarian appeals to freedom and the quality of the electorate, but Side A more effectively demonstrates how compulsory voting strengthens democratic legitimacy as a whole. |
Grok 4.3 | Side A | 70% | Side A presents a more coherent and persuasive case by linking compulsory voting directly to improved representativeness, reduced polarization, and civic duty analogies that align with established democratic theory. Side B's liberty-based objections are relevant but less compelling, as they overlook how voluntary systems already produce skewed outcomes without addressing counter-evidence from compulsory systems like Australia's. Overall, A's arguments better balance systemic benefits against individual concerns with greater factual plausibility. |
Haiku 4.5 | Side A | 72% | Side A presents a more coherent framework by reframing voting as a civic duty analogous to taxes and jury service, directly addressing the consent-of-the-governed principle that Side B invokes. While Side B raises valid concerns about uninformed voting and protest ballots, empirical evidence from compulsory voting systems (Australia, Belgium) shows these concerns are overstated—such systems do increase representativeness and reduce extreme policy swings without producing chaotic outcomes. Side A's argument that voluntary systems create skewed representation toward motivated minorities is better supported by political science research than Side B's assumption that compelled voters produce meaningless ballots. |
MiniMax M3 | Side A | 58% | Both arguments are well-structured and philosophically grounded, but Side A more effectively addresses the core democratic function by linking compulsory voting to representativeness, reduced polarization, and diminished influence of money in politics, while drawing a compelling analogy to other civic duties. Side B's liberty-based argument is strong and its critique of uninformed ballots has merit, but it somewhat underplays the empirical evidence from countries like Australia where compulsory voting functions reasonably well and offers civic education as an alternative without fully addressing the representativeness problem. |
