To blue or not to blue?

Correct. Everyone votes red and everyone survives.

There are two ways to interpret the problem:

  1. Red voters are voting to kill blue voters if they win
  2. Blue voters are voting to commit suicide if they lose

This is why I want to address the problem in a way that doesn’t depend on either of these interpretations.

All we need to ask is if the below argument is valid or not:

  1. Everyone survives only if either most vote blue or all vote red
  2. It is probable that at least one person will vote blue
  3. Therefore, I (we) ought vote blue

I say it is invalid. What do you say?

If it is invalid then the only things we need to consider are:

  1. Anyone who votes red survives
  2. Anyone who votes blue survives only if most vote blue

Therefore, I vote red. There is a rational reason to prefer voting red over blue and no ethical reason to prefer voting blue over red.
