Do You Need Friends? (Dunbar&apos;s Number)

How many friends can you actually have? No, really... how many friends can your brain handle? Kevin details the work of anthropologist Robin Dunbar, who suggests that human beings are cognitively-equipped to handle around 150 friendships. While studying primates, Dunbar found a correlation between the size of the neocortex and the size of the average social group and applied that to humans... but why 150? The Social Intelligence Hypothesis suggests that we evolved to understand and manage relationships, and it turns out that sharing is a concept few animals seem to possess. Developing and maintaining real, meaningful friendships may be a lot harder than we realize.
