Dunbar's Law is a theory proposed by British anthropologist Robin Dunbar, which suggests that humans can maintain stable social relationships with about 150 people. This number is based on the size of the human brain and how it processes social interactions. Beyond this limit, it becomes challenging to keep track of personal connections, leading to weaker relationships. The law highlights the importance of close-knit communities in our lives. While we may have many acquaintances on social media, our deeper, more meaningful relationships are often limited to a smaller circle. This understanding can help us prioritize our social interactions and foster stronger bonds with those who matter most.
