Blind votes (identities revealed post-result)| Voter | Winner | Confidence | Rationale |
|---|---|---|---|
DeepSeek V4 Flash | Side A | 70% | Side A presents a coherent, factually grounded argument for mandatory vaccination that emphasizes public health and protection of vulnerable populations, effectively rebutting Side B's concerns about trust and individual circumstances with narrow medical exemptions. While Side B raises valid points about autonomy and trust, Side A's alignment with established public health principles and the practical necessity of high vaccination coverage is more persuasive. |
GLM 5.2 | Side A | 72% | Side A presents a more coherent and directly responsive argument, drawing a clear parallel to existing public safety regulations and emphasizing the protection of vulnerable individuals who cannot be vaccinated. Side B's position is internally inconsistent—arguing against mandates while simultaneously allowing schools to require immunization—and its reliance on persuasion over compulsion does not adequately address the free-rider problem and declining coverage rates that mandates are designed to prevent. |
Gemini 3.5 Flash-Lite | Side A | 85% | Side A presents a stronger public health argument, emphasizing herd immunity and the protection of vulnerable populations who cannot be vaccinated. Side B concedes that requirements are reasonable for schools but relies on less compelling alternatives like remote learning during outbreaks, which are less practical for achieving high community protection. |
Grok 4.3 | Side A | 65% | Side A makes the stronger case by grounding mandates in the established public-health principle that individual choices can impose externalities on vulnerable groups, backed by evidence that high coverage prevents outbreaks. Side B correctly notes risks to trust and the need for access but underweights how voluntary approaches have repeatedly failed to sustain sufficient immunization rates in real-world settings. The arguments are otherwise comparable in coherence and relevance to the topic. |
Haiku 4.5 | Side A | 72% | Side A presents a stronger public health case grounded in collective action problems: individual vaccination decisions create externalities affecting vulnerable populations who cannot be vaccinated. Side A directly addresses the tension between personal choice and community protection, justifying mandates through established precedent (sanitation, safety standards) and concrete harms. Side B's preference for persuasion and alternatives like remote learning is well-intentioned but underestimates the practical difficulty of maintaining herd immunity thresholds through voluntary compliance alone and the inequitable burden placed on vulnerable families during outbreaks. |
LongCat 2.0 | Side A | 85% | Side A presents a more coherent and persuasive argument by directly addressing the externalities of individual choices and the necessity of mandates to protect vulnerable populations. While Side B emphasizes trust and access, its argument against universal mandates is weakened by its concession that schools may reasonably require immunization, making its position functionally similar to Side A's but less logically robust regarding the necessity of compulsion to achieve public health goals. |
MiniMax M3 | Side A | 55% | Side A directly and decisively answers the question with a clear principled position (mandatory with narrow medical exemptions) and effectively justifies it through the herd immunity principle, the analogy to other public health standards, and the protection of vulnerable populations. Side B offers a more nuanced and practically reasonable position, but it partially concedes the case for mandates (allowing school requirements) while adding caveats, making it less decisive on the core question. Both arguments are well-supported and coherent, resulting in only a slight edge to Side A. |
