It is a dilemma because pressing blue or red reveals about your political orientations and your inner empathic responses (i'm assuming both are correlated). Not everyone is wired the same or agrees on politics.
Though in a sense, i agree it's not really a dilemma because only sociopaths pick red in real life. See also intense and spontaneous cooperation in times of crisis (catastrophe, war, etc).

Nah pretty much everyone picks red if it was a real scenario. It's also bizarre to call everyone picking red a sociopath because they don't want to gamble their life on some naive and idealistic view of humans.
Believe what you want, the numbers disagree with you. As for the sociopath label, assuming psychopathy and sociopathy are the same thing, egocentrism and impaired empathy are central traits.
It was a pool in X where people that press blue were not going to die. They just lied to feel better.
Try again with money, everyone puts $1000 so it's real but nobody dies. Red pushers get their money back, everyone if >50% press blue. I like my version where 10% have miss wired buttons, so the % of people that will vote "incorrectly" is inside the model. Send the lost money to an Khmer Rouge advocacy group so nobody feels good about losing the money.
If you want a dilemma, it must be inside the model, for example: a 10% of the buttons are miss wired, and the system register the oposite color
So if red wins, at least 10% die. If blue wins, everyone survives. Now you have a dilemma. Which button would you press?
PS: If a country has 20 cities and one of them has a big majority of red-pressers, is it moral to nuke it out of existence?
