研究：你真正的朋友只有5个
How many friends do you really have?
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.
Whenever we add someone new to our social network, they argue, each new friend is actually slightly more distant than those of the inner circle.
他们认为,无论我们在什么时候从社交网络上添加新朋友,每位新朋友还是比我们圈子里的朋友要稍微有距离些.
It suggests that while we may have just a few friends, we can still surround ourselves with acquaintances.
这表明了我们可能只有几个朋友,但周围却围绕着一群熟人.
Michael Harré and Mikhail Prokopenko, both with the University of Sydney in Australia, said while we may only have five close friends, our social network from them can extend to 132 people.
来自悉尼大学的迈克尔•哈雷和米哈伊尔•普罗科彭科表示,虽然我们只拥有5个亲密朋友,但是我们可以通过他们把自己的社交网络扩展至132人.
The researchers built computer models to analyse human social networks and then compared them to hunter-gatherer societies.
研究者创建了电脑模型来分析人类社交网络,接着将分析出来的数据同采集狩猎社群进行对比.
