尽管个体之间一致的行为差异(即个性差异)现在在动物身上得到了很好的确立，但当个体在社会群体中互动时，这些差异并不总是表现出来。这在领导力等重要的社会动态中可能是关键，而领导力往往与大胆等个性特征呈正相关。个体在社交能力(社交能力)方面一直存在差异，因此，如果在社交互动中可以抑制其他人格变异的轴心，比如大胆，那么这种抑制在更善于社交的人身上应该会更强。我们测量了三刺刺鱼的胆量(独自离开避难所的潜伏期)和社交能力(与同种刺鱼共处的时间)，并对这些鱼的胆量-领导力联系进行了测试。大胆和善于交际都是可重复的，但并不相关。当将数据分成50%最爱社交的鱼和50%不爱社交的鱼时，大胆与不爱社交的人的领导力更紧密地联系在一起。这与更多善于交际的鱼的行为一致，因为它们有更大的社交倾向。因此，人格变异的一个轴(社交能力)可以调节其他人(胆量和领导力)之间的关系，这对社会动物的人格变异具有潜在的选择意义。
Although consistent behavioural differences between individuals (i.e. personality variation) are now well established in animals, these differences are not always expressed when individuals interact in social groups. This can be key in important social dynamics such as leadership, which is often positively related to personality traits such as boldness. Individuals consistently differ in how social they are (their sociability), so if other axes of personality variation, such as boldness, can be suppressed during social interactions, this suppression should be stronger in more sociable individuals. We measured boldness (latency to leave a refuge when alone) and sociability (time spent with a conspecific) in three-spined sticklebacks (Gasterosteus aculeatus) and tested the boldness–leadership association in pairs of these fish. Both boldness and sociability were repeatable, but were not correlated. When splitting the data between the 50% most sociable and 50% less sociable fish, boldness was more strongly associated with leadership in less rather than more sociable individuals. This is consistent with more sociable fish conforming to their partner's behaviour due to their greater social tendency. One axis of personality variation (sociability) can thus modulate the relationship between others (boldness and leadership), with potential implications for selection on personality variation in social animals.
