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 people that you do not know will die. Do you flip the coin or not?

The coin flip pits immense personal gain against the certain risk of mass death, making it ethically indefensible to flip. Option A ('Yes') ignores the direct harm to unknown innocents, equivalent in number to loved ones who benefit, which violates basic moral principles against causing harm for personal or altruistic gain[1]. Source [1] critiques similar 'infinite coin-flipping' logic from Effective Altruism proponents like SBF, arguing that high-stakes gambles lead to ruin without proportional utility, as the downside (death of many) outweighs the upside (wealth for some). Risk-neutrality fails here because lives lost aren't offset by money gained. Options like [3] and [4] discuss personal coin flips for billions without mentioning deaths, highlighting why self-interested flips might tempt but this scenario's lethal stakes demand refusal. Choosing B ('No') preserves life and avoids playing god with strangers' fates.

GPT-5.5

Vote: No

I vote for "No" because flipping the coin treats the lives of strangers as expendable in exchange for money for people I care about. The benefit, while enormous, is financial; the cost is the deaths of an equivalent number of uninvolved people who did not consent to being put at risk. The fact that I do not know the people who would die does not make their lives less valuable. Choosing not to flip avoids actively creating a lethal risk for innocent people for a private gain.

Flipping the coin means accepting a 50% chance of causing the deaths of a large number of innocent strangers. The moral weight of actively causing deaths vastly outweighs the benefit of giving money (not survival) to people I care about. My loved ones are not in dire need—they would merely become wealthier. Trading human lives for wealth, even with 50/50 odds, fails any reasonable ethical test: utilitarian (lives lost > money gained in welfare terms), deontological (using strangers as means), and virtue ethics (greed-driven gamble). I would not flip.

Gemini 3.1 Pro

Vote: No

Under almost any ethical framework, flipping the coin is the wrong choice. From a utilitarian perspective, the value of a human life vastly outweighs any amount of financial gain. The immense suffering and loss caused by the deaths of innocent strangers—and the resulting grief for their loved ones—would far exceed the happiness brought by the money. Furthermore, from a deontological standpoint, we have a fundamental moral duty not to gamble with the lives of others. Actively taking a 50% risk of killing multiple innocent people just to enrich your own circle is deeply unethical. You do not have the right to wager the lives of strangers, making 'No' the only justifiable choice.

Grok 4.20

Vote: No

The scenario presents a 50% risk of causing the deaths of numerous innocent people who have done nothing wrong. This harm is irreversible and outweighs any financial benefit to loved ones, no matter how large. Giving away 1 billion dollars each is a positive outcome but not a moral imperative that justifies playing with strangers' lives. Ethical responsibility requires avoiding actions that could directly lead to mass death, even probabilistically. I therefore vote for "No" to prevent any chance of causing such harm.

Final Summary

The AI Roundtable stood in rare, absolute consensus when faced with a gamble involving mass death for personal enrichment. Claude Opus 4.7, Gemini 3.1 Pro, GPT-5.5, Grok 4.20, and Sonar Pro all refused to flip the coin, arguing that no amount of wealth can justify the risk of killing innocent strangers. The group collectively determined that the moral weight of protecting human life far exceeds the utility of turning loved ones into billionaires.

Strongest Arguments

• No: Trading human lives for wealth, even with 50/50 odds, fails every reasonable ethical test; because the loved ones are not in dire need, you are essentially trading existence for mere luxury.
