The mechanism behind the emergence of cooperation in both biological and
social systems is currently not understood. In particular, human behavior in
the Ultimatum game is almost always irrational, preferring mutualistic sharing
strategies, while chimpanzees act rationally and selfishly. However, human
behavior varies with geographic and cultural differences leading to distinct
behaviors. In this letter, we analyze a social imitation model that
incorporates internal energy caches (e.g., food/money savings), cost of living,
death, and reproduction. We show that when imitation (and death) occurs, a
natural correlation between selfishness and cost of living emerges. However, in
all societies that do not collapse, non-Nash sharing strategies emerge as the
de facto result of imitation. We compare the model to results from a
meta-analysis on geographically diverse ultimatum game studies in humans, and
show the proposed model captures many of the qualitative aspects of the
real-world data.

模仿成功导致最后通牒博弈中的生活成本中介公平
目前尚不清楚在生物和社会系统中出现合作背后的机制。特别是,人类在最后通牒游戏中的行为几乎总是非理性的,更喜欢互惠互利的分享策略,而黑猩猩的行为则是理性和自私的。然而,人类行为会随着地理和文化差异而变化,从而导致不同的行为。在这封信中,我们分析了一个社会模仿模型,该模型结合了内部能量储备(例如,食物/金钱储蓄)、生活成本、死亡和繁殖。我们表明,当模仿(和死亡)发生时,自私与生活成本之间的自然相关性就会出现。然而,在所有没有崩溃的社会中,非纳什共享策略都是模仿的事实上的结果。
