AIBU to wonder which button people would press to survive?

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?

Red or blue
Red- aibu
Blue-ainbu

You havent understood the riddle have you?

No, I do not get these types of things at all. They are never going to happen, so I do not understand why peopel call eachother names over them.

I will mash both buttons together. But I will be more worried and asking why I was in that situation to start with.

Morons, selfish, stupid, pillocks etc.
I am pressing blue to get rid of you lot who just want to use a hypothetical situation to finally get to call people names.

I feel like saying one would press blue just outs one as either a dangerously naive optimist, or an insincere virtue signaller.

And I have to think that it's very easy to say that one would press blue...but if it were real, and one was standing in front of the buttons...I wonder how many people would actually press blue. Very few, I think. Self-preservation is a strong instinct.

I am going for virtue signalling personally. In the moment when its a guarantee for being selfish or a risk for being altruistic, it would be reds all the way.

FourSevenThree · 09/05/2026 22:17

I suppose part of the issue is a definition of everyone.

Are we talking about toddlers? Blind people having assistance to recognise which one is which or having to pick randomly?

IIf I imagine only people with capacity pushing the buttons, I'd see red as the best choice- everyone can press their own survival.

If absolutely everyone including young children who can't coached, I might have more faith in world-wide coordination leading to more than half blues.

PyongyangKipperbang · 09/05/2026 22:08

But it really isnt. If everyone who wants to live picks red then they are guaranteed to live either way.

Anyone who picks blue is a pillock!

It’s actually scary how many people would choose red and give themselves a pat on the back for doing so. You only need more than half the people to choose blue so it’s a pretty small gamble with huge rewards.

What rewards? Everyone lives? Is that a reward? Frankly, as somewhat of a misanthrope, it's win/win for me, pressing the red.

I know every close to me would press red, so whatever happens, I'm golden.

PyongyangKipperbang · 09/05/2026 22:07

I always work on logic, so yes I would press red.

Red I will definitely live, blue I might not.

Brilliant article by an actual philosopher of all things on this and similar scenarios (fans of game theory, consider this your trigger warning 🤣)

I will be getting in the blender and asking someone to press the button, because these things are bullshit and just gets people calling each other stupid over an impossible situation.

You don't betray a stranger by choosing to live. We all had the same information, i am not responsible for their choice or the consequences, they are not responsible for mine, or the consequences.

I agree with you. I would press red.

We are not discussing game theory, we are discussing the OP‘s question

Who some idiot on twitter has written because they misunderstood game theory and missed out on the actual interesting debate that comes with it.

This is a simple “everyone lives or everyone dies” choice. So everyone would choose red so that everyone can live, with no personal risk to yourself.

Prisoner’s dilemma, game theory, comes with risk no matter what. And it’s about weighing up that risk - choosing for yourself, even though there could be a slightly bad outcome but it’s better than nothing, or choose for the group even though it could mean you get nothing. That’s an interesting discussion. This is just stupid people vs anyone with a brain, because there is an option that has no personal or group risk of everyone goes for it. So everyone would.

People are choosing blue, not because of morality but because of a lack of knowledge or intelligence.

For an actual moral debate, there needs to be three outcomes with risk/reward for the group be risk/reward for the individual. That gives a debate on morality.

This question gives a debate on stupidity. Only stupid people would pick blue, and I’d assume in a life or death situation that people could figure out that everyone will be thinking “red is guaranteed survival” so everyone would choose it. There is no downside. There needs to be personal downside and risk for this to become a morality debate.

This. The only real, sensible choice is the red button. Anyone who presses blue is not thinking clearly at all.

You are totally missing the point here, yes ‘stupid’ people will press the blue button The moral part is whether you want to try and save those people or let them die. This could include young children, people who are mentally impaired (conditions like dementia), low IQ or other reasons for not being able to comprehend.

I’m sure you do. Just like all the posters on the legal board who say nonsense advice and then say “I have a law degree.” Or people on the mental health boards who tell you to just smack your autistic kid and then say they have a degree in psychology.

Good luck on your philosophy journey. But I don’t know why philosophers who don’t know what the prisoner’s dilemma is.

Thank you! I'm not big into game theory, and I'm also not a fan of analytical philosophy as it's so rigid. But always great to hear a different perspective!

No one would get in the blender. It can run empty and no one gets hurt. There needs to be another outcome, like a small amount of damage to everyone if no one gets in the blender.

Game theory has three outcomes.

A)Great for everyone in the group.

B)Good for the person who “betrays” but really bad for the person who doesn’t.

C)Somewhat bad for all, but at least guarantees survival/prize/freedom - just not as good as it would be if everyone cooperated.

Or people who choose the blue pill are choosing to put the control over whether they live or die in then hands of random strangers. No thanks.

“It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change.” Charles Darwin.

You are clearly wrong or all the answers would say red. That’s the whole point of the question, it’s that people think there is a moral dilemma when actually the logical common sense choice would be to red but as you can see, loads of people think that picking blue is somehow morally better? Thinking that people who choose blue could be mentally impaired or have accidentally pressed it and we need to save those people by also choosing blue. That’s why it is going viral and there is a lot of discussion around it.

People are choosing blue, not because of morality but because of a lack of knowledge or intelligence.

No, pressing red doesn’t come with risk because philosophically speaking, no one would pick blue. There is no personal risk to choose red and there is no group risk to everyone choosing red. There is personal and group risk to choosing blue. Everyone would choose red because we would all understand that everyone else can u first and the question and see the obvious choice with no risk or downside.

This isn’t game theory. How many times do I need to explain an actually moral dilemma game theory scenario?
