Red vs Blue, the Final Examination

We're deciding this shit once and for all so we never have to think about this stupid bullshit ever again.

Alright, y'all, you've had enough, I've had enough, but it's time to examine this question critically one last time, look at the common angles and reframings, and arrive at a final conclusion on the two button debate (spoiler, red voters are wrong)

The original button question is not really about finding a mathematically “correct” answer. Its purpose is philosophical. It exists to expose how you view other people.

More specifically, it asks a single underlying question:

> Do you believe humanity is fundamentally selfish, or fundamentally altruistic?

That may not be the first thing people consciously think about when they encounter the hypothetical. Many red-button advocates focus only on guaranteed self-preservation. Many blue-button advocates focus only on maximizing survival overall.

But whether people explicitly realize it or not, their choice ultimately depends on what they believe everyone else will do; that, in turn, depends on what they believe human nature is.


The Original Prompt

> “Everyone on earth takes a private vote by pressing a red or blue button. If more than 50% of people press the blue button, everyone survives. If less than 50% of people press the blue button, only people who pressed the red button survive. Which button would you press?”

The two most common responses are predictable.

The first is:

> “Red is the obvious answer, because it guarantees your survival regardless of what anyone else does.”

The second is:

> “Blue is the obvious answer, because a simple majority allows everyone to survive.”

Immediately, the argument splits into two competing moral frameworks.

Red-button advocates accuse blue voters of recklessly gambling their lives for no reason:

> “Blue voters are morons because they are risking death when they could simply guarantee their own survival.”

Blue-button advocates accuse red voters of selfishness:

> “Red voters knowingly choose the option that results in deaths when universal survival is possible.”


The Endless Reframings

The debate then spirals into countless reframings:

  • The blue button becomes “voluntarily entering a death gamble.”

  • The red button becomes “voting for a dictator who kills non-supporters.”

  • The blue side becomes “jumping into a woodchipper unless enough others do too.”

  • The scenario becomes poison, seesaws, spikes, drowning chambers, and so on.

But most of these reframings distort the original structure of the problem rather than clarify it.


The Real Issue: Risk

The real issue underneath all of this is risk, specifically:

  1. What creates risk,

  2. What accepts risk,

  3. And what pushes existing risk onto others.

To understand the button dilemma properly, those three things have to be separated.


The Apple, Orange, and Gunman

Lets Imagine a simple situation.

Before I go on, It is important to note here that this analogy is not meant to directly mirror the original button hypothetical. The purpose of the apple, orange, and gunman examples is only to isolate and demonstrate the mechanics of risk itself: where risk originates, who accepts it, and who transfers it onto others. Any connection drawn back to the button scenario is not meant as a one-to-one analogy between apples and buttons or gunmen and voters, but purely as a framework for understanding the moral structure of imposed risk.

Onwards:

You are offered an apple and an orange. Under normal circumstances, neither choice carries any danger. Choosing one fruit over the other is morally and physically neutral.

Now introduce a gunman.

The gunman says:

> “If you choose the apple, I will shoot you.”

Now the apple appears “risky.” But importantly, the risk does not come from the apple itself. The apple did not create danger. The gunman did.

The apple merely became associated with an externally imposed threat.

If you still choose the apple, then you are accepting risk, but you are not creating it.

Now modify the scenario again.

There are now two people in the room. The gunman says:

> “If either person chooses the apple, I will shoot both of you.”

Now the situation changes morally.

Choosing the apple still does not create the danger, (the gunman remains the source of risk) but choosing the apple now does two things simultaneously:

  • it accepts risk for yourself,

  • and it pushes the existing risk onto the other person.

That distinction is critical.


Returning to the Button Hypothetical

Now return to the original button hypothetical.

Red-button advocates frequently blame blue-button voters for their own deaths:

> “If blue voters die, it’s because they chose the risky option.”

But this framing collapses under scrutiny.

The button system itself introduces the danger. Neither side created the rules. The hypothetical already exists before anyone votes. The implementer of the system, the one enforcing the consequences, is the original source of risk.

The question then becomes:

> Which choice merely accepts risk (and from who?), and which choice pushes risk onto others?

To answer that, it helps to isolate the button effects themselves.


Isolating the Buttons

People often obsess over the “50.1% majority” threshold, as though that number itself contains the moral meaning of the scenario. But the threshold is arbitrary. Majority mechanics only matter because everyone is required to participate.

Remove that assumption and the structure becomes clearer.

Imagine that anyone who would have voted red instead abstains entirely.

Now only blue votes exist.

Blue automatically becomes the majority, and the result is:

> Everyone survives.

Notice what this means:

Blue, in isolation, contains no lethal consequence whatsoever. If only blue votes exist, nobody dies. This remains true regardless of how small a minority blue voters would otherwise represent. A single person voting blue, a thousand, a million, or a billion, if blue is the only vote cast, the outcome is always identical: everyone survives.

Now reverse the situation.

Imagine anyone who would have voted blue instead abstains entirely.

Now only red votes exist.

Red automatically becomes the majority, and the result is:

> Only red voters survive.

Therefore, everyone who abstained dies, because they did not vote red.

This demonstrates something important:

> The lethal outcome is tied to red victory conditions, not blue victory conditions.

Blue does not inherently contain death.

Red does.

This is why it is inaccurate to frame blue as “the dangerous option.” The danger is not built into blue. Blue only becomes dangerous because red voters create the conditions under which blue voters are excluded from survival. This completely disqualifies any reframing that presents blue as such, such as the blender and woodchipper reframing, the train reframing, the poison politician reframing... pretty much every reframing red pushers love to peddle.


# “But Red Voters Didn’t Create the System”

This leads to the common red-button defense:

> “But red voters didn’t create the system.”

And strictly speaking, that is true.

  • Red voters did not design the buttons.

  • They do not tally the votes.

  • They do not personally execute the losers.

The implementer of the hypothetical created the danger.

But this does not absolve red voters morally, because moral responsibility is not limited only to originating harm. There is also responsibility for distributing harm.

Returning to the gunman example:

The person choosing the apple did not create the threat, but they still pushed the existing danger onto the second person.

Likewise, in the button scenario:

  • Blue voters accept risk for themselves,

  • while red voters push the existing risk of the system onto blue voters.

That is the key distinction.

Blue voters are not choosing death.

They are choosing universal survival conditional on cooperation.

Red voters are choosing guaranteed personal survival conditional on excluding others.

That is why accusations of selfishness toward red voters are not merely emotional rhetoric. They follow directly from the structure of the hypothetical itself.

It cannot be denied that pressing red guarantees your survival regardless of outcome. But that guarantee comes at a cost:

your safety is achieved by participating in a condition where non-red voters are abandoned to death if your side wins.

That is the definition of self-preservation at others’ expense.


The Real Core of the Debate

And once that point is established, the debate loops back to the original philosophical core:

> What do you believe about humanity?

Red-button advocates fundamentally assume that enough people are selfish that cooperation cannot be trusted. Their worldview treats self-preservation as the only rational response because they expect others to behave selfishly too.

Blue-button advocates fundamentally assume that enough people are capable of cooperation that universal survival is achievable.


The Polling Problem

This final point becomes especially visible whenever real-world polling enters the discussion.

Large online polls asking this hypothetical routinely show blue winning *decisively*.

And yet red-button advocates almost always dismiss this evidence with some variation of:

> “People are only choosing blue because the vote isn’t real.”

or

> “They’re virtue signaling.”

or

> “If lives were actually on the line, everyone would choose red.”

But this response is revealing.

Even when presented with evidence that large numbers of people claim they would cooperate, red-button advocates refuse to believe it. Their worldview requires assuming hidden selfishness beneath outward altruism.

In other words, they cannot believe humanity is genuinely cooperative, because they themselves are unwilling to cooperate.


Conclusion

And that ultimately brings the entire discussion to its conclusion.

The red position only remains morally defensible if one begins with the assumption that humanity is fundamentally too selfish to cooperate. Under that worldview, the choice collapses into a simple survival calculation: either guarantee your own life or gamble it away. If that assumption about humanity is true, then red becomes pragmatically understandable.

But that assumption is subjective, speculative, and impossible to prove in advance.

What can be examined objectively is the structure of the choice itself.

And structurally, red voters are not merely “protecting themselves.” They are securing their own survival through a framework that knowingly transfers danger onto others. They participate in, and benefit from, a condition where nonparticipants in their strategy are left to die.

  • Blue voters accept risk for the sake of universal survival.

  • Red voters avoid risk for themselves by externalizing it onto everyone else.

That is why the repeated attempts to frame blue as the uniquely “reckless” or “irrational” option fail under scrutiny. The actual moral burden lies with the side choosing exclusionary survival.

So while the hypothetical does not produce an absolute mathematical proof of morality, it does reveal something uncomfortable:

outside of the assumption that humanity is irredeemably selfish, the red position becomes increasingly difficult to morally justify.

And that is why red advocates so often retreat back to cynicism about humanity itself. It is the final refuge of the argument.

Once the assumption of universal selfishness is removed, pressing red ceases to look like mere rational self-preservation and begins to look exactly like what blue voters accuse it of being: selfishness elevated above collective survival.

And to be perfectly clear: choosing blue is not a sacrifice. It is a bet that your survival and everyone else's survival are the same bet. Red is a bet that your survival requires everyone else's survival to be someone else's problem. That distinction is the moral core of the entire question.

Blue only appears moral because of vague wording.

The blue button only appears moral because of the deliberately vague descriptions and sanitized language in the original problem: "people will survive unless...", "if X, everyone survives...", etc.

Assign any method by which "people will not survive", and the truth is shown for what it is: the blue button is a SAW movie contraption, and the blue pushers have Stockholm syndrome for the evil puppet.

Examples:

Blue button releases a pack of hungry lions. If blue wins, we cancel the release. Red does nothing.

Blue button releases poison gas in the room if blue wins, we hand out the antidote. Red does nothing.

Blue button activates a bomb in the building. If blue wins, the bomb doesn't explode. Red does nothing.

And so on and so forth. Im every case, the red button doesn't actually do anything except refusing to participate in this twisted game.

Red with minor sacrifice for safety

If blue wins everybody lives and if it loses blue voters die as usual. If you press red you sacrifice one of your hands to be safe from death.

If you have no hands you lose a foot, if you have neither you can have a freebie. It leaves behind an already healed stump so you won't bleed out or something. You can choose which hand and the process is quick and painless.

Does introducing a small (compared to a life) cost to safety change anything for you?

I guess this is a question mostly for red voters since it changes nothing for blue voters. If blue wants something to think about then maybe an alternate version where red loses (blue percentage)/3 of their body instead so that increasing blue costs red something and technically 100% red or 100% blue are the only scenarios with zero consequences.

Because there are 2 factors in people dying, both sides share responsibility for any deaths.

I have been arguing with a red pusher for a few days now and I want to see if my logic is reasonable.

People only die if 2 conditions are met at the same time:

  1. That person picked blue. The person who picked blue is entirely responsible for their choice of button. Red did not force anyone to pick blue.
  2. Red is in the majority. The people who picked red are collectively responsible for red winning. Blue did not contribute to the red majority.

Because people die if and only if both conditions are met and no one can contribute to both factors at the same time, this means that the responsibility for every death is split as such: 50% of the responsibility lies on the person who died for picking blue, while the other 50% is shared equally among all people who picked red for being in the majority.

In short: Picking blue kills you if and only if red wins.

Is there something I am missing?

Edit: this is also assuming that no one knows the outcome ahead of time.

Edit 2: the responsibility for red comes from knowing you could have been the reason blue died.

Simple Question

If this was a real world scenario I completely understand why any one would pick either button. I don’t care why you make your choice. Doesn’t matter to me. Not interested in that. Do your thing!

I am curious about something though that I feel like I am seeing in some of the back and forth.

This is my question:

If the problem was worded like this, do you think the problem has been inherently changed?

Every one must take a private vote by picking a red or blue button.

If less than 50% press red, then everyone lives.

If more than 50% press red, then only the people who pressed the blue button die.

Only toddlers

Lets suppose all toddlers in the world are presented the 2 buttons and along with them, so are you. So basically you have no idea how its gonna turn out because its probably just gonna be entirely random. So now, do you vote blue, or red? Voting blue contributes towards saving everybody but carries the huge risk of dying along with probably half the entire toddler population, while voting red contributes towards wiping out probably half the entire toddler population but saves yourself.

The reason why I came up with this variant is because it slighly irks me when people consider toddlers and mentally handicapped people to be eligible voters for this thought experiment because imo in order to take away anything useful from it we must assume that voters understand the situation

Let's remove morality from the equation by removing survival from the dilemma

Let's say everyone is gonna play a game. It's just a game, no one's gonna die. The game is simple:

You push a red or blue button, votes are tallied, you may receive penality points as follows:

  • if a blue majority is created, there are no penalty points.
  • if a blue minority is created, you get penality points based on the number of blue votes.

Everyone's goal is to vote so that you get the minimum number of penality points, without communications.

Let's say people really really don't like even a single penality point. What would you vote?

edit:

I think I should have been more clear as to what I wanted to do. A wanted a variation where survival is removed, but also personal incentives as well. I understand this isn't the same as the original, but the functionalities of the button is kept the same.

So which button do you press to minimize penalty points? Is it the same or different from the original? what's your pick and what do you think the results will be?

“Red is killing”

I disagree with the very common assertion that voting red is killing the people who voted blue. In my opinion the situation itself is doing the killing.

Your home is swarmed by masked men in the middle of the night. You’re grabbed and bagged and taken away. The kidnappers give you two options:

If you ask to be let go, they’ll let you go
If you ask to stay, you’ll stay kidnapped.

If more than half of the people who have been kidnapped ask to stay, they’ll let everyone go. If the majority of the people ask to be let go, they’ll kill everyone who asked to stay.

In this situation, would you blame any of the people who just asked to go home? Does their “vote” come with any malice?

The life or death stakes exist from the onset of the situation, and leaving the situation does not hamper anyone else’s ability to do the same.

I understand why you might pick blue but I don’t understand how you can see someone as a killer for not risking their life.

Question about trust / If the presser population was only your country what would you choose?

I am in no way here to cast judgement on any color anyone chooses.

However, I’m just really curious. If you were put in this scenario in real life, with people from all over the world pushing the button, before we talk about all of the (of course valid) reasons you press blue—do truly trust 50% of humanity to press blue? Even if they eventually think of all the reasons you do?

If yes, I’d be curious to hear where you come from, since that probably has a lot of impact on our perception of community and trust. If this was just in your country, would you feel safer pressing blue?

For example, I’m an American and I kind of feel like blue pressers would be fucked.

Excited to hear everyone’s thoughts :)

The expected reward of voting blue

https://www.desmos.com/calculator/lnm6kehhey

Variables:

y: How much you value your own life (in lives).
x: The minimum % of blue voters that is probable.
n: The total population
R: The count of possible vote outcomes/n

Assume a uniform distribution of all possible votes. If you think the blue vote will be between 25% and 75%, we are assuming all outcomes in that range are equally probable.

Is a tie possible?

If you think a tie is impossible, or rather that 50% is not within the range of possible blue vote outcomes, then the problem is simple.

Either this means blue is guaranteed to succeed, in which case it doesn't matter how you vote, or blue is guaranteed to fail in which case vote red.

For the rest of this, however, we will be dealing with the third case where a tie (excluding you) is possible.

The probability that you are the tiebreaker.

There is only 1/n % chance out of all possible votes that you will be the tiebreaker, assuming that a tie is possible.

So the probability that you will be the tiebreaker is 1/n/R

The probability that you will die if you vote blue

You will die whenever less than half the population votes blue.

Since x is the lower bound of possible blue voting percentages, this means there are 50% - x chances for you to die.

>Let's say the lower bound is 25%
50% - 25% is 25%. So we have a range with a space of 25% representing possible vote outcomes where a blue vote means death.
Note that this range does not include exactly 50%. If it did then we would need to add 1/n to make the range inclusive.

And since we still have R different possible votes the probability you will die is (50% - x)/R

Rewards

If you are the tiebreaker, voting blue gives you a reward of n/2 lives, half the population.

This happens 1/n/R times, so the expected reward from being a tiebreaker is 1/2/R = 1/2R

Meanwhile the cost for voting blue when less than half the population votes blue is your own life, valued as y lives.

So the expected cost of voting blue is y*(50% - x)/R

When is blue better?

Blue is better when the expected reward for voting blue is greater than the expected cost.

y*(50% - x)/R < 1/2R

Multiply both sides by R (a positive number)

y*(50% - x) < 1/2

Divide both sides by (50% - x)

y < 1/(2*(50% - x))

y < 1/(1 - 2x)

This so whenever you value your life less than 1/(1-2x) lives you should vote blue.

Alternatively we can solve for x to see how much you would need to value your before you would vote red.

1-2x<1/y
-2x < 1/y -1
x> (1 - 1/y)/2

https://www.desmos.com/calculator/lnm6kehhey

y: How much you value your own life x (minimum blue %) such that voting blue has a better reward than voting red
1 life 0%
2 lives 25%
3 lives 33%
5 lives 40%
8 lives 43.75%
15 lives 46.47%
25 lives 48%
50 lives 49%
100 lives 49.5%

---

The key assumption here is that there is a uniform distribution of probability from x to at least 50%.

A normal distribution would likely do a better job estimating, or some other distribution, but since we are essentially guesstimating to begin with a uniform has the advantage of being easy to visualize.

If you want a quick way to set your parameters, think of what you expect the value to be, and then give a value between 0% and 100% for how certain you are that this will be the value. Then subtract (1-your certainty) from your expected value and set that as the lower bar.

Another key assumption is that y can be represented by a number. People presumably will be more or less willing to die to save y number of people depending on circumstances. A person might be wholly unwilling to die to save 5 people by donating all their organs, but might be very willing to risk a 20% chance of death to protect 1 person from an attack.

The best way to address this is to simply think of y in context of this particular vote. Maybe imagine that you are voting for another person who you don't know, who has communicated explicitly to you that you should make whichever choice you prefer without particular deference to their interests. Then compare that to how you would feel if it was your own life on the line.

Lastly people don't value the lives of others uniformly. A parent might be unwilling to die to save 100 people, but be willing to die to save their child.

How strong is your conviction?

The exact same problem, blue button >50%, red button no die.

BUT, just before you vote, you are informed that if you team wins, the new world will be run by 50+ year old hardcore flat earther creationists youtuber podcasters, you can divert your hand to vote for the other button now, do you still go through with your original plan?

Alien sociologists on a field trip.

Aliens come to Earth looking to study humans. Their ethics prohibit them from forcing humans to come with them (or tricking humans into it with false promises, etc). However, they telepathically find a few thousands people who would be willing to simply volunteer to leave Earth behind and come with them.

One of the humans suggests pulling a hilarious prank: before volunteers leave, aliens announce that all humanity will be forced to take a classic private red/blue button vote. Humanity has a week to coordinate. During the actual vote aliens aren't even keeping track of the votes. After the votes are cast only the people who originally volunteered to go with the aliens are replaced with very convincingly looking dead bodies (of themselves) while the volunteers themselves are safely teleported away. Aliens depart. For everyone else on earth it looks like red button won the vote and the volunteers were the only ones who actually voted blue. Also all volunteers were telepathically prevented from leaking the information about this ongoing prank and their planned departure while they stayed on Earth and aliens don't leak that information either.

Share your ideas what will happen back on Earth after aliens depart.

What if before the vote, you get to make a global speech, for what botton would you advocate for?

Caveats (consider or not them in your response, as I think they make the question more interesting):

1 - Let's say that you choose on behalf of those who are close to you.

2 - At the time of the voting, everyone gets to read three different sets of rules: one framed in favor of Blue, one in favor of Red, and the last one neutral.

In this scenario, Blue seems like the obvious choice, but I cannot picture myself voting Blue when the time comes. I deeply see it as a "life gamble"—one that I would never make, even less so for those who are close to me.

I don't believe that, even with a global speech, we would have a 100% chance of more than 50% voting Blue, and I would not risk my life on that. In that position, I would advocate for the Red Button by the logic that it guarantees your safety without relying on anybody else.

If children are voting, or if a fixed percentage is going to vote Blue no matter what, then I would vote Blue. But otherwise, the idea of putting myself in danger because somebody decided to put themselves in danger unnecessarily is something I wouldn't do. I also don't think this is uncommon logic. (hence the reason for me choosing Red)

How to test this experiment out in the real world?

A lot of people I’ve spoken with and work with are interested in this but obviously death is too severe to realistically test this out. What are fun punishments that willing participants would agree to do? With my girlfriend we have similar bets the first to lose we do something random like eat a whole tomato because I hate tomatoes. Does anyone have any suggestions for what a punishment should be in this hypothetical?
