Be sure to follow the rule before you head out.
Rule: You must post before you leave.
Isn't the point of the prisoner dilemma that isn't always better for you to do the bad thing but it's best for all if both don't?
Which is exactly this - the bad thing is to pull the lever and kill two extra people. It's not as bad for you, like in the prisoners dilemma, since they're not known to you. The best thing for all is for no one to pull a lever and you each lose one loved one rather than all your loved ones.
