Correct. Everyone votes red and everyone survives.
There are two ways to interpret the problem:
- Red voters are voting to kill blue voters if they win
- 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:
- Everyone survives only if either most vote blue or all vote red
- It is probable that at least one person will vote blue
- 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:
- Anyone who votes red survives
- 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.
