In a study that involves simulations of dynamic networks it has been found that a paradoxical norm, the right to hospitality, is a good human conflict resolution strategy fostering cooperation. This is different in the animal kingdom in general, where territoriality is widespread. Human hosts more easily concede on their home turf than guests. An example given involves one piece of food that has to go to either the host or the guest. A better understanding of this behaviour may improve human conflict resolution approaches.
