Herding behavior has a social cost for individuals not following the herd, influencing human decision-making. This work proposes including a social cost derived from herding mentality into the payoffs of pairwise game interactions. We introduce a co-evolutionary asymmetric model with four individual strategies (cooperation vs. defection and herding vs. non-herding) to understand the co-emergence of herding behavior and cooperation. Computational experiments show how including herding costs promotes cooperation by increasing the parameter space under which cooperation persists. Results demonstrate a synergistic relationship between the emergence of cooperation and herding mentality: the highest cooperation is achieved when the herding mentality also achieves its highest level. Finally, we study different herding social costs and its relationship to cooperation and herding evolution. This study points to new social mechanisms, related to conformity-driven imitation behavior, that help to understand how and why cooperation prevails in human groups.
羊群行为会给不随大流的个体带来社会成本，影响人类决策。这项工作建议将源自羊群心理的社会成本纳入两两博弈互动的收益中。我们引入了一个具有四种个体策略（合作与背叛以及从众与不从众）的共同进化不对称模型，以理解羊群行为和合作的共同出现。计算实验表明，纳入羊群成本如何通过增加合作持续存在的参数空间来促进合作。结果证明了合作的出现与羊群心理之间的协同关系：当羊群心理也达到最高水平时，合作程度最高。最后，我们研究了不同的羊群社会成本及其与合作和羊群进化的关系。这项研究指出了与从众驱动的模仿行为相关的新社会机制，有助于理解合作在人类群体中如何以及为何盛行。
