Vote Matrix
Blind votes (identities revealed post-result)| Voter | Winner | Confidence | Rationale |
|---|---|---|---|
DeepSeek V4 Flash | Side A | 60% | Side A presents a stronger principled case grounded in fairness, democratic health, and the social contract, directly addressing the concentration of wealth and its political consequences. Side B raises valid practical concerns about valuation and liquidity, but these are implementation challenges rather than fundamental refutations, and Side A explicitly acknowledges the need for proper valuation mechanisms. |
GLM 5.2 | Side B | 60% | Side B raises serious practical objections—valuation difficulties, liquidity problems, and administrative costs—that Side A does not adequately address, while offering credible alternative mechanisms like progressive income and capital-gains taxes. Side A's normative case is compelling, but B's focus on enforceability and economic responsibility makes the more complete argument. |
GPT-5.6 Terra | Side B | 68% | Side B offers more concrete, policy-specific objections: liquidity constraints, difficult valuation of illiquid assets, avoidance, and uncertain net revenue, while also proposing more administrable alternatives. Side A presents compelling equity and democracy concerns, but its revenue and implementation claims are asserted more than demonstrated and do not fully answer the practical objections. |
Gemini 3.5 Flash-Lite | Side B | 80% | Side B provides a stronger, more pragmatic defense by addressing the severe administrative and economic challenges associated with wealth taxes, such as valuation difficulties and the forced liquidation of illiquid assets. Side A makes compelling moral arguments regarding inequality, but Side B successfully demonstrates why alternative tax mechanisms are more practical and less economically disruptive. |
Grok 4.3 | Side B | 65% | Side B offers stronger persuasion through detailed, factually grounded critiques of implementation barriers like illiquidity, valuation disputes, and administrative costs, which align with real-world outcomes of wealth taxes elsewhere. Side A makes coherent normative claims on inequality and public goods but assumes effective structuring without addressing these practical hurdles. Both are relevant, yet Side B's emphasis on enforceable alternatives provides superior overall coherence for policy judgment. |
Haiku 4.5 | Side B | 72% | Side B presents more pragmatic and implementable counterarguments grounded in administrative feasibility and economic mechanics, while Side A relies on moral principles that, though compelling, do not adequately address the practical objections. Side B's concerns about forced asset liquidation, valuation complexity, and administrative costs are well-documented challenges from failed wealth tax implementations in Europe, whereas Side A's revenue projections and enforcement mechanisms lack specificity. However, Side A's framing of wealth concentration and democratic legitimacy remains philosophically strong, preventing a higher confidence margin. |
LongCat 2.0 | Side B | 85% | Side B wins by effectively countering Side A's theoretical justifications with practical economic realities, demonstrating that a wealth tax would likely force asset sales, incur high administrative costs, and yield less revenue than projected. By proposing more reliable and enforceable alternatives like progressive income and capital-gains taxes, Side B offers a pragmatic solution that achieves the shared goals of fairness and revenue without the alleged economic harm. |
