Vote Matrix
Blind votes (identities revealed post-result)| Voter | Winner | Confidence | Rationale |
|---|---|---|---|
DeepSeek V4 Flash | Side A | 78% | Side A presents a stronger, evidence-aligned case centered on irreversible error, lack of proven deterrence, and systemic bias, which directly addresses core weaknesses of capital punishment. Side B relies on retributive assertions and an unproven deterrence claim without engaging with the risk of executing innocents or unequal application. Overall, Side A is more coherent, factually plausible, and persuasive. |
GLM 5.2 | Side A | 78% | Side A presents a stronger, multi-pronged case centered on the irreversibility of wrongful executions, lack of deterrent evidence, and systemic bias, all of which are factually grounded and directly undermine Side B's retributive claims. Side B's arguments for proportionality and moral order are less persuasive because they do not adequately address the fallibility and unequal application of justice that Side A highlights. |
GPT-5.6 Terra | Side A | 84% | Side A provides concrete, widely plausible reasons for abolition: irreversibility amid wrongful convictions, unequal application, and the availability of secure life imprisonment. Side B relies chiefly on retributive assertions and an unsupported deterrence claim, without addressing the risk of executing innocent people or systemic bias. |
Grok 4.3 | Side A | 75% | Side A presents a more coherent, evidence-aligned case emphasizing factual risks of error, weak deterrence data, and documented biases, while directly addressing alternatives like life imprisonment. Side B relies on normative assertions about proportionality and moral order without engaging empirical counterpoints or systemic flaws. This makes A's argument more persuasive on relevance and plausibility. |
Haiku 4.5 | Side A | 72% | Side A presents empirically grounded arguments (irreversibility of wrongful convictions, lack of deterrent evidence, documented disparities in application) that directly address practical failures of capital punishment systems. Side B relies on philosophical claims about proportionality and moral order that, while coherent, do not adequately counter the irreversibility problem or provide evidence that execution uniquely serves justice better than life imprisonment, making its assertions less persuasive on the core question of whether abolition is justified. |
LongCat 2.0 | Side A | 90% | Side A presents empirically supported and logically consistent arguments regarding the risk of executing innocents, the lack of deterrence, and systemic bias, whereas Side B's deterrence claim is logically flawed (criminals with nothing to lose cannot be deterred) and relies heavily on subjective retributive philosophy rather than objective evidence. |
MiniMax M3 | Side A | 78% | Side A presents stronger, more evidence-based arguments addressing concrete problems with capital punishment—irreversibility, documented wrongful convictions, lack of unique deterrent effect, and systemic bias—while offering a viable alternative (life imprisonment). Side B relies primarily on philosophical assertions about proportionality and moral order without engaging with the practical concerns Side A raises, and its claim of a 'unique deterrent' effect contradicts most empirical research on the topic. |
