In a recent paper, we showed that leadership arises from individual behavioral differences in pairs of foraging stickleback (Gasterosteus aculeatus). Foraging data from randomly combined pairs of fish were analyzed using Markov Chain models to infer the individual movement rules underlying joint behavior. While both fish responded to partner movement, bolder individuals were the least responsive and showed greater individual initiative. Shy partners were more faithful followers and were also found to bring about greater leadership tendencies in their bold partners. The ability of such followers to inspire bolder fish suggests that leadership may be dependent on individual temperament differences, reinforced by social feedback.
在最近的一篇论文中，我们表明领导力源于觅食棘鱼（三刺鱼）成对个体的行为差异。使用马尔可夫链模型分析了随机组合的成对鱼类的觅食数据，以推断联合行为背后的个体运动规则。虽然两条鱼都会对伙伴的运动做出反应，但更大胆的个体反应最小，且表现出更大的个体主动性。害羞的伙伴是更忠实的追随者，并且还被发现会在其大胆的伙伴中引发更大的领导倾向。这种追随者激励更大胆鱼类的能力表明，领导力可能取决于个体气质差异，并受到社会反馈的强化。
