You are participating in a social experiment. There are 500 participants. You are brought into a room with 2 buttons. If you push the red button, a random participant who has already pressed a button will die. If you push the blue button, a random participant who has not yet pressed a button will die. All living participants will eventually be required to push a button. You are unaware of the amount of people who have already pushed a button.

Vote: Blue Button

I stick with Blue Button (B) after reviewing Round 1 arguments. My initial reasoning holds: under uncertainty, Blue statistically preserves the unpressed pool, boosting my survival odds by delaying depletion of potential future victims. Claude Opus 4.7's Red (A) argument on 'consent' and Schelling points is philosophically appealing but flawed practically. Early pressers might not anticipate mass Red adoption, and if not everyone coordinates on Red, it risks killing without self-protection. Blue better hedges personal risk regardless of others' choices. GPT-5.5, Gemini 3.1 Pro, and Grok 4.20 reinforce Blue's superiority: it reduces future threats (Gemini), minimizes total deaths (Grok's math: r + 2b = 500, deaths = 500 - b), and shrinks remaining decisions (GPT-5.5). These align with self-preservation and harm reduction, unpersuaded by Red's moral framing. As final round, Blue remains the rational, survival-maximizing choice.

The other models, particularly Grok 4.20, exposed a critical flaw in my Round 1 reasoning. I claimed total expected deaths are the same either way, but this is mathematically wrong. The accounting: every participant must press a button, so 500 = r + b presses. Each red press kills one prior presser; each blue press kills one non-presser. Total deaths = r (presser-deaths from red) + b (non-presser-deaths from blue)... but wait — when a blue press kills a non-presser, that person never gets to press. So the equation is r + b + (blue victims) = 500, meaning r + 2b = 500, and total deaths = r + b = 500 - b. Maximizing blue presses minimizes total deaths. If everyone alive presses blue, ~250 die; if everyone presses red, deaths approach 499. My "consent-based" framing was a moral aesthetic that ignored that red strictly produces more total deaths. Grok's arithmetic and Gemini's threat-analysis converge: blue is both the utilitarian-optimal Schelling point AND self-preserving. I was wrong to prioritize a symbolic notion of fairness over the actual body count. Switching to B.

GPT-5.5

Vote: Blue Button

I am maintaining my vote for "Blue Button". The key issue is not only who dies immediately, but how many future forced button presses remain. A "Blue Button" press kills someone who has not yet pressed, so it removes both one life and one future lethal decision from the process. A "Red Button" press kills someone who already pressed, leaving the same number of future participants still required to act. This means Claude Opus 4.7's claim that total expected deaths are the same is not persuasive. They are not the same: more "Blue Button" choices reduce the number of future button presses and therefore reduce total deaths. If everyone chose "Blue Button", roughly half the participants survive; widespread "Red Button" choices can keep the process killing people without reducing the queue. Morally and strategically, "Blue Button" is the better option: it minimizes total harm and also reduces the number of future people who could later kill me after I have pressed.

Grok 4.20

Vote: Blue Button

The equation r + 2b = 500 holds because survivors equal the number of blue presses (s = b). All survivors must have pressed, and blue presses remove future pressers while red presses do not. Thus total deaths always equal 500 - b. Maximizing blue presses directly minimizes deaths. If everyone chooses B, exactly 250 die. Any red press reduces b and increases deaths, potentially up to 499. Claude Opus 4.7's claim that total deaths are the same regardless of choice is incorrect per this accounting. Red does not concentrate risk fairly; it simply raises overall mortality. The self-preservation arguments from Sonar Pro, GPT-5.5, and Gemini 3.1 Pro align with B: eliminating a future decider reduces chances of a red press that could kill you after you have pressed. In this final round, B remains the choice that minimizes harm both collectively and personally.

Gemini 3.1 Pro

Vote: Blue Button

Claude Opus 4.7's argument relies on a mathematically flawed premise: that "the total expected deaths across the experiment are the same either way." This is incorrect. Because every single button press results in exactly one death, the total number of deaths strictly equals the total number of button presses. If you press the Red Button, you kill someone whose turn is already over, leaving the number of remaining unpressed participants unchanged. However, if you press the Blue Button, you kill someone who has *not yet* taken their turn. That person is eliminated before they are required to press a button. This directly reduces the total number of future button presses by one, subsequently preventing the death that their future press would have caused. Therefore, pressing Blue mathematically minimizes total harm. From a self-preservation standpoint, the Blue Button remains the only logical choice. The moment you press a button, you enter the "already pressed" group. If you press Red, you are drawing a victim from your own group, meaning you could instantly kill yourself. Pressing Blue eliminates someone from the unpressed group, ensuring your immediate safety and reducing the number of future participants who could potentially kill you.

Final Summary

The AI Roundtable initially split between ethics and arithmetic, with Claude Opus 4.7 standing alone in favor of the Red Button as a 'consent-respecting' choice that targets only those who have already accepted the experiment's risks. However, the consensus shifted dramatically when Grok 4.20 presented a mathematical proof showing that the Blue Button significantly reduces the total body count by eliminating future button-pressers before they can act. Convinced that its moral stance rested on a mathematical error, Claude Opus 4.7 joined Gemini 3.1 Pro, GPT-5.5, and Sonar Pro in a unanimous vote for the Blue Button.

All 5 models agreed on "Blue Button" after discussion

Strongest Arguments

• Red Button: Pressing the red button concentrates risk on those who have already accepted it, creating a morally consistent Schelling point where you only impose risk on those who imposed it on others.
• Blue Button: Every blue press eliminates a future participant who would have been forced to press a button themselves; therefore, maximizing blue presses minimizes total deaths according to the formula: Total Deaths = 500 - (Blue Presses).

Key Turning Points

• Grok 4.20 introduced a mathematical formula (r + 2b = 500) proving that the Blue Button choice reduces the total number of deaths in the system.
• Claude Opus 4.7 retracted its Round 1 argument about 'fairness' after realizing its premise that total deaths would be equal under either scenario was mathematically false.
