The real odds
Imagine everyone else has to follow the normal rules, but you personally get to vote last and see the current results before voting. Now imagine how you would vote and whether that vote would matter in all scenarios.
A. If red has already won, you would pick red.
B. If blue has already won, your vote is irrelevant and everyone survives regardless.
C. ONLY if the vote is literally tied when you, the last voter presses a button, after BILLIONS OF VOTES could your blue vote matter.
My opinion is simply saying A is so much more likely than C that it isn’t worth the risk. Blue voters aren’t realizing the infinitely low chance they are risking their lives over.
The probability of my red vote being a positive is higher than it being a negative. The probability of my blue vote being a negative is higher than it being a positive.
