The theory of Dunbar’s number holds that we can only really maintain about 150 connections at once. Dunbar concluded that the size, relative to the body, of the neocortex – the part of the brain associated with cognition and language – is linked to the size of a cohesive social group.
Why can I only have 150 friends?
The community level of organisation turned out to be almost exactly 150. Thus was born the “social brain hypothesis” and “Dunbar’s number”, the former referring to the relationship between group size and brain size in primates and the latter referring to the natural group size of about 150 for humans.
How many social connections does the average person have?
average American has an overall network of 634 social ties.
What is Dunbar theory?
An anthropologist and evolutionary psychologist, Dunbar’s fame largely focuses around a single number; 150. The theory of Dunbar’s Number posits that 150 is the number of individuals with whom any one person can maintain stable relationships. The genesis of Dunbar’s theory was a man by the name of Bill Gore.
How many friends is too many?
How Many Friends is Too Many? You need Dunbar’s Number. Proposed by anthropologist Robin Dunbar in 1992, Dunbar’s number represents the number of relationships we are cognitively able to manage and to which we can legitimately feel connected at a given time. That number is 150.
Why is Dunbar’s number 150?
In a 1993 study, Robin Dunbar, a British anthropologist, theorized that humans could have no more than about 150 meaningful relationships, a measure that became known as Dunbar’s number. The neocortex in humans is even larger, so he extrapolated that their ideal group size was, on average, 150.
How many meaningful relationships can a person have?
By using the average human brain size and extrapolating from the results of primates, he proposed that humans can comfortably maintain 150 stable relationships.
Why having lots of friends is bad?
Friendship goes hand in hand with certain implied obligations and expectations. And people with lots of friends may not be able to fulfill those obligations — especially people with too many friends. Having lots of friends means your precious social resources become diluted, making you less able to be a good friend.

Whatever its perceived shortcomings, technology offers endless possibilities for facilitating social connection — not as a replacement for human contact, but as a vehicle for developing and reinforcing relationships. And it’s never too late to start.
Why are some social networks larger than 150?
Some US social networks cluster around 290 in size, rather than 150 (Credit: Emmanuel Lafont) There are also critiques of Dunbar’s number on methodological grounds. Primates’ brain sizes are influenced by other aspects besides social complexity: factors such as dietmay explain them too.
