或许我们在线上社交网络中可以有5000个好友,但是科学家们发现,人类大脑最多只能够管理150个朋友。
Oxford University Professor Robin Dunbar has conducted a study of social groupings throughout the centuries, from neo-lithic villages to modern office environments.
牛津大学教授罗宾·邓巴针对若干个世纪以来的社会群组进行了研究,研究对象从新石器时代的村落一直延伸到现代办公室。
His findings, based on his theory 'Dunbar's number', developed in the 1990s, asserts that size of the part of the brain used for conscious thought and language, the neocortex, limits us to managing 150 friends, no matter how sociable we are. And he defined 'maintained' friends as those you care about and contact at least once a year.
他的研究结果基于他1990年代的理论“邓巴数字”。该理论认为,大脑内负责有意识思想与语言的区域——新皮质(大脑皮层的背面)的大小限制了我们,就算我们再爱社交,也只能管理150个朋友。他将“能维持住的”朋友定义为那些你给予关心而且每年至少联系一次的朋友。
距离牛津大学罗宾·邓巴教授的研究结果问世已经过去了二十多年,有人怀疑,社交媒体的涌现,可能会改变Dunbar教授声称的“150人”上限。
For the past few years, there's been a lively conversation about whether the rise of Facebook, Twitter and other social networks is making staying in touch so easy that the Dunbar number ought to be recalibrated. In a world where gregarious people routinely have 1,000 or more friends on Facebook, shouldn't the Dunbar number climb accordingly?
