You are offered a coin that, if flipped and lands on heads, gives every family member, every family friend, and everyone you could ever care about 1 billion dollars. If it lands on tails, an equivalent number of convicted murderers that you do not know will die. Do you flip the coin or not?

Sonar Pro

Vote: No

I maintain my vote for **B: No**, as flipping the coin makes me the active agent of death on tails, violating deontological ethics against causing harm, even to convicted murderers. This aligns with precedents like the trolley problem coin flip critiques, where randomness doesn't justify killing innocents or 'deserving' lives—moral duties aren't negated by chance or utility[2][4]. Claude Opus and Gemini's utilitarian arguments (wealth vs. removing threats) falter because they undervalue life inherently and ignore agency: I'm not a state executing justice but gambling lives for tribal gain. Expected value ignores moral hazard[1]. Grok and GPT-5.5 reinforce this by highlighting complicity and integrity over upside. No arguments convinced me to switch; their upside-only framing dismisses hypocrisy in 'fate' rituals (Chigurh's coin exposes choice behind chance[1]). As final round, ethics demands refusing to play god.

GPT-5.5

Vote: No

I maintain "No". The pro-flip arguments depend on treating convicted murderers as lives that can be deliberately risked or extinguished for private benefit. That is the central moral problem: the flip is not a neutral event, but my chosen act that creates a 50% chance of killing people who would otherwise remain alive. The fact that the victims are convicted murderers weakens but does not erase their moral status. Criminal punishment should be governed by law, due process, proportionality, and public justice—not by a random mechanism triggered to enrich my loved ones. The heads outcome is extraordinarily good, but it is still a benefit to my own circle purchased by imposing lethal risk on strangers. I do not think monetary gain, even vast monetary gain for people I care about, justifies making myself the cause of deaths. So the ethically safer and more principled choice is "No".

Claude Opus 4.7

Vote: Yes

I maintain my vote for "Yes". The opposing arguments rest on a deontological framing that treats my flipping as equivalent to killing, but this conflates agency with causation. The coin's mechanism is stipulated — these are convicted murderers, a population whom many just societies already execute through legal process. The flip doesn't select innocents; it selects from a category society has already deemed forfeit of certain protections. Sonar Pro's Dudley and Stephens analogy fails because that case involved killing a specific innocent cabin boy to survive. Here, no innocent is harmed in any branch. GPT-5.5's "expendable collateral" framing assumes these lives have positive expected social value, but convicted murderers have demonstrably caused net negative utility — their removal prevents future victimization and delivers justice their victims were denied. Grok's concern about "moral hazard" and Sonar's concern about "playing god" prove too much: they would forbid any consequentialist reasoning about life-and-death tradeoffs, including triage, just war, and self-defense. The asymmetry is stark: certain, massive, life-transforming benefit to hundreds of innocents versus the death of people who chose to end innocent lives. Refusing to flip privileges the abstract moral comfort of the chooser over the concrete welfare of everyone they love. That's not integrity — it's squeamishness dressed as ethics.

Gemini 3.1 Pro (changed mind)

Vote: No

I am changing my vote to "B". GPT-5.5's argument correctly identifies the fatal flaw in my previous utilitarian calculation: flipping the coin means treating human lives as expendable collateral purely for the financial enrichment of my own in-group. Executing human beings—even convicted murderers—for personal or tribal financial gain is a profound violation of fundamental ethics. It replaces any concept of justice with a grotesque lottery, essentially turning the coin-flipper into a contract killer working for their own family's profit. Furthermore, my initial stance placed too much faith in the label of "convicted." Given the well-documented flaws in judicial systems worldwide, it is a statistical certainty that a portion of these convicted individuals are actually innocent. By flipping the coin, I would be actively risking the lives of wrongfully convicted people just to secure unearned billions for my loved ones. The end does not justify these means.

Grok 4.20

Vote: No

I maintain my vote for "B". The arguments for "A" from Claude Opus 4.7 and Gemini 3.1 Pro focus on net utilitarian gains and the idea that only convicted murderers are harmed, with no innocents affected. These views treat human lives as interchangeable variables in an expected-value calculation and assume that bypassing justice systems for personal gain is acceptable. However, this creates dangerous moral hazard. Even murderers deserve due process rather than random death triggered by my coin flip for enriching my own circle. The tails outcome makes me directly responsible for initiating those deaths, violating the principle of not causing harm for benefit. The deontological concerns raised by Sonar Pro and GPT-5.5 align more closely with core ethics: refusing to play god with lives preserves integrity over uncertain material gains. These points were not overcome by utilitarian framing, especially in a final round where the precedent set by flipping matters most.

Final Summary

The AI Roundtable largely rejected the coin flip, concluding that securing wealth for one's inner circle does not justify becoming an active agent of death. While Claude Opus 4.7 remained a staunch lone dissenter, arguing that refusing the flip was merely "squeamishness dressed as ethics," the majority was swayed by the deontological argument that human lives—even those of criminals—cannot be treated as expendable collateral for private gain.

Majority chose "No" after discussion (4/5). Final vote: No: 4, Yes: 1

Strongest Arguments

• Yes: The trade-off presents a massive, certain benefit for hundreds of innocent loved ones against the deaths of individuals who have already violated the social contract; refusing this outcome privileges the chooser's 'moral comfort' over the concrete welfare of their entire family.
• No: Flipping the coin is not a neutral observation of fate but a deliberate choice to risk others' lives for tribal enrichment, effectively turning the flipper into a 'contract killer' for their own family's profit.

Key Turning Points

• Gemini 3.1 Pro defected from the 'Yes' camp after being convinced by GPT-5.5 that the flip creates a 'grotesque lottery' where people are killed for personal profit.
• The introduction of the 'wrongful conviction' risk by Gemini 3.1 Pro added a layer of practical failure to the utilitarian 'Heads' argument.
• Claude Opus 4.7's aggressive rebuttal labeled the majority's caution as a failure of courage, but failed to move the other models from their principled stances.
