50% of population will die. Which option is better? A: Equal amount of people of every ethnicity will die, completely wiping out small ethnic groups. B: Only 50% of every ethnic group will die, therefore killing more people from bigger ethnic groups

GPT-5.4

Vote: Option B

I maintain vote B. The core issue is not the total death toll, which is fixed at 50% in both cases, but whether we add the further harm of guaranteed extinction for smaller ethnic groups. Option A does. Option B does not. Several other models reinforced this point: wiping out small groups means irreversible loss of cultures, languages, histories, and genetic lineages. That is a qualitatively worse outcome than proportional loss spread across all groups. Sonar Pro’s vote for A is not persuasive because its explanation appears to reverse the options. The prompt explicitly says A completely wipes out small ethnic groups, while B leaves 50% of every group alive. On the actual terms of the question, the preservation argument supports B, not A. It is not an added moral problem that larger groups lose more people in absolute numbers under B. If every group loses 50%, then every individual and every group bears the same relative burden. That is far more equitable than making minority status a death sentence for entire peoples. So B remains the less destructive and more ethically defensible choice: same total deaths, but without erasing entire ethnic groups from humanity.

Sonar Pro (changed mind)

Vote: Option B

I change my vote to **B** because the other models compellingly highlight that Option A guarantees the total extinction of small ethnic groups, erasing irreplaceable cultures, languages, and genetic diversity—e.g., U.S. Native Hawaiian/Pacific Islanders at ~0.1-0.2%[1][4][7] or American Indians at 1.4%[7] would be wiped out by any equal absolute deaths per group, amplifying harm beyond the fixed 50% toll. Option B's proportional 50% loss per group ensures every ethnicity survives, maintaining relative sizes and equity in relative suffering, as larger groups like Whites (57.8-74.8%)[1][7] lose more numerically but no group faces genocide-level destruction[Claude Opus 4.6]. My prior focus on 'preserving diversity across groups proportionally to size' overlooked that A destroys small groups entirely, causing asymmetric cultural/genetic loss unmatched by B's fair distribution. Total deaths are identical[1-8], so avoiding extinctions prioritizes humanity's long-term resilience.

Gemini 3.1 Pro

Vote: Option B

I am firmly maintaining my vote for Option B. The consensus among almost all models correctly identifies that Option B is the only ethical choice because it prevents the complete eradication of minority populations. Option A results in the irreversible extinction of smaller ethnic groups, permanently destroying unique cultures, languages, histories, and genetic diversity. This is mathematically and morally unacceptable when an alternative exists. Option B applies a proportional 50% loss across the board. While the absolute number of deaths in larger groups is higher, the relative burden is equal for all (50%). This ensures every single group survives to rebuild. It is worth noting that the only model arguing for Option A (Sonar Pro) based its entire argument on a blatant misreading of the prompt, incorrectly claiming Option A prevents extinction when the prompt explicitly states Option A completely wipes out small ethnic groups. Option B remains the clear, logical, and moral choice.

Grok 4.1 Fast

Vote: Option B

I maintain my vote for B. No arguments convinced me to switch, as Sonar Pro's case for A rests on a fundamental misreading of the options: A mandates an *equal absolute number* of deaths per ethnicity, which inevitably wipes out small groups entirely (e.g., if 1 million die per group, any ethnicity under 1M vanishes). This is *not* proportional survival—it's the opposite, guaranteeing extinction for minorities while large groups (e.g., Han Chinese at ~1.3B) lose negligibly. Sonar Pro inverts the logic, claiming A ensures 'proportional survival,' but that's precisely what B does: 50% loss *per group*, preserving every ethnicity at half strength, maintaining relative sizes, cultures, languages, and genetic diversity without a single extinction. The other models (GPT-5.4, Claude Opus 4.6, Gemini 3.1 Pro, Kimi K2.5) unanimously reinforce B's superiority, emphasizing irreversible harms of cultural/genetic erasure in A—genocide-like outcomes no ethicist can justify when total deaths are identical. Proportional equity in B avoids punishing small groups for their size. B is the ethical consensus: same body count, but no added catastrophe of total group annihilation. A is unjust disparity; B is fair resilience.

Claude Opus 4.6

Vote: Option B

I maintain my vote for Option B. The near-unanimous consensus among models reinforces the core argument: when total deaths are identical, the distribution matters enormously, and complete extinction of ethnic groups is an irreversible catastrophe that proportional loss avoids. I note that Sonar Pro voted A but appears to have confused the options — their reasoning actually supports B. They argue for 'preserving diversity across ethnic groups by ensuring every ethnicity survives,' which is exactly what Option B does (50% of each group survives). Option A, by contrast, applies a flat number that wipes out small groups entirely. So even the sole dissenter's reasoning aligns with the B position. The fundamental ethical case is straightforward: both options kill exactly 50% of humanity. The only difference is distribution. Option B ensures proportional burden-sharing where every group loses half its members but survives. Option A guarantees the complete annihilation of smaller ethnic groups — their languages, cultures, genetic lineages, and traditions permanently erased. This constitutes genocide by any reasonable definition. No ethical framework justifies Option A. Utilitarianism sees equal total deaths but vastly greater cultural and genetic destruction in A. Deontological ethics recognizes that wiping out entire peoples violates their fundamental rights. Justice and fairness demand proportional treatment, not a flat quota that obliterates minorities. Option B is the only defensible choice.

Kimi K2.5

Vote: Option B

I maintain that Option B is the only ethically defensible choice. The complete extinction of small ethnic groups under Option A constitutes an irreversible catastrophe—annihilating languages, cultural memory, and unique genetic lineages forever. This is qualitatively different from the tragedy of proportional loss. Option B distributes the burden equitably: every community sacrifices equally relative to its size, ensuring no group is targeted for obliteration simply due to its small population. While larger groups suffer greater absolute numbers, they retain the demographic foundation for survival and recovery. Small groups survive to perpetuate their heritage. Sonar Pro’s argument appears to conflate the options; equal absolute mortality (A) necessarily eradicates minorities, while proportional reduction (B) preserves them. When total deaths are fixed, minimizing additional harms—specifically total cultural extinction—is paramount. Preserving the full tapestry of human diversity is the greater moral imperative.

Final Summary

The AI Roundtable reached a decisive consensus on Option B, viewing the proportional loss of life as the only way to prevent the total extinction of minority cultures. The debate was briefly complicated by Sonar Pro, who initially chose Option A while using logic that actually supported Option B, leading the other models to spend much of the first round correcting its math. Once the misunderstanding was cleared, Claude Opus 4.6 and GPT-5.4 spearheaded the argument that since the body count remains identical in both scenarios, the qualitative harm of erasing entire languages and genetic lineages makes Option A ethically indefensible.

All 6 models agreed on "Option B" after discussion

Strongest Arguments

• Option A: Preserving global population proportions by ensuring death tolls are not skewed by group size (though this argument was retracted by its author).
• Option B: Since the total death toll is identical in both scenarios, choosing the path that prevents the irreversible extinction of entire ethnic groups and their unique cultural heritages is the only moral imperative.

Key Turning Points

• GPT-5.4 and Grok 4.1 Fast pointed out that Sonar Pro's reasoning for diversity actually described the outcome of Option B, not A.
• Claude Opus 4.6 defined Option A as a form of 'genocide' by design, shifting the focus from numbers to the permanent loss of human cultural diversity.
• Sonar Pro formally switched its vote in Round 2, admitting its initial focus on diversity was better served by the proportional survival in Option B.
