You’ve probably seen or heard of this thought experiment.
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?
This thought experiment has been shared around the internet since at least 2023, but it recently resurfaced after Tim Urban shared it on X.
The debate splits into two major camps.
The main argument for pressing blue is that it’s the only choice that saves everybody. If enough people vote blue, everyone lives. The main argument for pressing red is that it’s the only choice that guarantees your own survival.
And yet red-pressers can never seem to leave it at that.
Red-pressers feel so compelled to explain and rationalize their decision because of the cognitive dissonance that comes with pressing red.
Research shows that most people strongly believe that they are morally good people. This thought experiment creates a real psychological problem because pressing red shatters that self-image.
“How can I be a good person if I chose to condemn others to death to save myself?”
So they try to justify it. They say everyone can survive if everyone presses red. If you press blue, you’re banking your life on half the world also pressing blue. Some have gone as far as to reframe the question, calling red the “nothing happens” button and blue the “suicide” button or the “ultimate death gamble.”
But it doesn’t matter. You can rationalize it all you want but you know what you did.
Blue voters don’t feel the need to explain themselves because there’s no cognitive dissonance. Their choice lines up with how they see themselves.
Assuming that self-preservation is a basic human instinct, one that people will prioritize over anything else, it’s possible that red will win in a true life or death scenario. But what does the world look like after every blue-presser is gone?
Red guarantees your survival, but it places you in a world where everyone knows exactly what everyone else did. The person next to you voted to sacrifice half the population to save themselves. Social trust and collective thinking are disproven as human traits. Human civilization runs on cooperation, and all you have now are people who are less likely to cooperate if cooperation doesn’t benefit them.
It’s a world where people will not return their shopping cart, won’t let you merge into their lane, won’t hold the door open for someone behind them, won’t donate blood, won’t leave honest reviews online.
The paradox is that if red wins, it poisons the survivor pool. Blue is the only outcome actually worth surviving into. A world of red-pressers is a punishment, and blue-pressers won’t be around to suffer the consequences.
So perhaps the real question we should be asking is whether you want people to help you even if it doesn’t benefit them?
