Many of us may have lists of contacts and followers on social media networks that extend into the thousands, but new research has found we may actually only have five real friends. 我们中的许多人通讯录里的联系人和社交媒体网络上的好友可以增加到数千人，但是新研究指出，事实上我们拥有的真正意义上的朋友可能只有5个。 A team of scientists have found that while humans have the capacity to form complex layered societies, we face an upper limit to how many friends we can have in our inner circle. 一个科学家团队发现，人们可以构建纷繁复杂、层次分明的社会群体，而在自己的社交圈里，我们拥有的朋友数量是有上限的。 They say this upper limit of five has likely gone unchanged for hundreds of thousands of years and probably governed social relationships when humans lived as groups of hunters. 他们表示，几十万年来，5个朋友的上限可能从未改变，或许从人类集体狩猎开始，这种模式一直掌控着人际关系。 |
