Dunbar's Number exists as a result of the limited processing capacity of the human brain. British anthropologist Robin Dunbar proposed that humans can only comfortably maintain 150 stable relationships because of the size of our neocortex, the part of the brain responsible for social interactions and higher order thinking

Understanding Dunbar's Number is important because it highlights the natural limits of social connections and the depth of relationships humans can manage. This awareness can lead to more meaningful social interactions, better management of social networks, and insights into organizational dynamics and community building.

To use Dunbar's Number to your advantage, prioritize and invest in relationships that are genuinely meaningful and beneficial to you. Recognize the value of having a smaller, closer network of connections rather than striving for a larger, less meaningful social circle. This can improve mental health, enhance the quality of social interactions, and lead to more fulfilling relationships.

While Dunbar's Number itself is not typically used against individuals, a misunderstanding or ignorance of these social limitations can lead to the dilution of meaningful connections in favor of superficial relationships. Social media platforms may exploit this by encouraging an ever-expanding network of contacts, which can overwhelm individuals and detract from the quality of real interpersonal connections.
