Dunbar’s Number is the limiting number of trusting relationships that a person can maintain. Tribes are known to naturally split after surpassing a population of 150 members. Splitting of the tribes creates a natural Us-vs-Them dynamic. This dynamic often leads to war between tribes unless the two groups can cooperative dynamics. As is typically seen in game simulations, a group in a cooperative environment can switch to retaliatory leading to complete dominance over all other groups. This begs the question, what amount of war is necessary for long term stability of peace?
