社会冷漠的博弈分析

Analysis by Game Theory on Phenomena of Social Indifference

社会中人的行为表现出交互性和强烈的影响性。群体行为演化模拟表明,一个群体或社会中冷漠者的存在会导致整个群体社会的冷漠化。博弈论视野下,相关约束机制不存在,因受利益驱使,会使冷漠成为每个社会成员的占优策略,进而随着时间的变迁,社会冷漠现象将会大量存在。道德机制的引入,使原有博弈的收益结构发生变化,援助成为博弈的唯一纳什均衡,援助不再使冷漠成为每个人的优势策略,社会冷漠现象自然逐渐消失。

The behavior of a social man displays a sort of interactive and reciprocal influence. Evolutionary simulation of group behavior demonstrates that the existing of indifference will result in group inclination of indifference. From the perspective of game theory, the deficiency of related restraint mechanism will make indifference be dominant strategy of every social member. However, the introduction of morality mechanism has changed the original structure of the game＇ s gains, and has helped to make it into the sole Nash equilibrium of the game, thus offering a helping hand for the natural disappearance of social indifference instead of making it every member＇s dominant strategy.
