You and another incredibly smart human have to chose an answer (of the three) in secret. You differ you die. Which one do you chose? To me this is the correct answer. I don't think the other two would even be in consideration. I also think aliens would agree, although I'm not sure that would be fair since the original question (on this website) is being asked to me, a human. [edit] Interesting this is also not the exact Bertrand paradox since they perhaps have added units to it to get around Edwin Jaynes solution *See Wiki
