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.
