A great deal of fiction (The Stand, Lord of the Flies, The Experiment, Survivor) purport that in the face of catastrophy or bare bones survival, man will turn on himself until only one remains.
I think the 33 men stuck in the Chilean mine for 69 days proved that all wrong. Not only did they work together to ensure the group's survival but they surpassed their individual abilities to emerge triumphant in spirit as well as body. Apparently, they've hired an accountant to create a fund in which to place the profits from the telling of their experiences so that each man, from the quietest to the most exuberant, will share the wealth.
Take that William Golding.
