Social media promises us an ever-expanding circle of friends, but that may be an empty promise. Social behavior is firmly rooted in biology, and our brains are hard-wired to maintain meaningful relationships with no more than around 150 people.
In an SFI Community Lecture on March 12 in Santa Fe, evolutionary psychologist Robin Dunbar explored how our brains have evolved to support the complex social structures that ensure our survival, and how the sizes of our social groups are defined by our DNA. Dunbar's research suggests real limits not only to our personal relationships, but to the size and capacity of every community in which we participate -- Facebook “friends” and Twitter “followers” included.
