This has resurfaced and been trending for a while

Everyone in the world has to take 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?

Currently at 42.1% red and 57.9% blue.

What would you choose? (See also r/slatestarcodex discussion)


I was motivated to post because I have a convincing argument for blue:

  1. Stupid people will choose blue. You may not care about the disabled, elderly, generally moronic, etc. but this includes children and people who are "too generous": nice, but emotional, and devote their lives to charity

  2. Thanos snapping a decent amount of the population (including random children, and biased towards selflessness) will probably overall negatively affect society

  3. I probably won't die because most people choose blue, as evidenced by the poll. Even if I do, it may be preferable to living with the survivors (point #2)

There are two ways to phrase the question. This way is phrased here basically demands Blue.

Rephrase it like this and I think there would be more Red pushers:

Everyone in the world has to take a private vote by pressing a red or blue button. Everyone who presses the red button will live with no risk of death. If you press the blue button, you will die unless more than 50% of people also press the blue button.

Phrasing this way demonstrates that the blue button pressers are creating a risk of death which doesn't really need to be there.

But what about kids? I think adding a (those who are incompetent or underage will have their button pushed by their parent/guardian) parenthetical would change it even more.

Because consider the parent now. If you asked a parent, "Which button would you press for your kid, the one where they will always survive or the one where they might die?" I think most parents would press the red button without a second thought.

Basically this. If you don't immediately perceive that a vote for blue is a vote to be killed, perhaps you deserve that outcome.

This kind of clause defeats the point. The point is everyone gets the question at the same time and must decide instantly. In that context your choices are:

  1. Press Red, guarantee your survival, hope everyone you love also chooses Red or that enough people choose Blue. If Red wins, live with knowing you might have had the defining vote (assume nobody knows the exact split of the final outcome) however unlikely.

  2. Press Blue, either die instantly with a clean conscience or everyone lives.

Why do you assume it's an instant death and not a slow drawn out painful death?
