Variation: Decrease risk, Increased threshold
All of humanity has been kidnapped and placed alone in a dark room with two buttons, and the following explanation perfectly translated into their native language.
🔴 : Ensures Survival, but will lead to half of blue pressers dying if more that 1/3 of people press this button.
🔵 : Everyone lives if 2/3 of people vote for Blue, but half of people who vote Blue will die if the threshold is not reached.
Everyone can only press one button once before both buttons break and becomes unpressable. Everyone is given 10 hours to vote, and if anyone chooses not to vote for any reason (including incompetence), then they are randomly assigned a button (2/3 chance of getting Blue, 1/3 chance of getting red.)
All of humanity means every living human being. There have been no exceptions for any reason.
Everyone has all of this information, and everyone is given 2 full hours to fully comprehend all of this information before they are allowed to start voting.
So, how do you vote?
