What Makes Us Moral and The Morality Quiz. It's war time, and you're hiding in a basement with a group of other people. Enemy soldiers are approaching outside and will be drawn to any sound. If you're found, you'll all be killed immediately. A baby hiding with you starts to cry loudly and cannot be stopped. Smothering it to death is the only way to silence it, saving the lives of everyone in the room. Assume that the parents of the baby are unknown and not present and there will be no penalty for killing the child. Could you be the one who smothered it if no one else would?

"He asks each of them to write down...any dollar integer between 2 and 100 without conferring together. If both write the same number...he will pay each of them that amount. But if they write different numbers, he will ... pay both of them the lower number along with a bonus and a penalty--the person who wrote the lower number will get $2 more...and the one who wrote the higher number will get $2 less.... For instance, if Lucy writes 46 and Pete writes 100, Lucy will get $48 and Pete will get $44."

What amount would you choose? And what does your answer tell us about the limits of Game Theory?
