The reason the human brain is more complex and sophisticated than that of other primates is to facilitate the establishment of social relationships. The brain develops through the senses, and humans must experience them to sense. Without experience, the human brain cannot perceive. All social experiences contribute to the development of a social brain. The broader the relationships, the more socialized the human brain becomes. Through experience, the human brain can compare and organize information to communicate effectively with other brains. To empathize, we mirror the brains of others. Who we are with is also neurologically essential. - Joseph’s “just my thoughts”
British anthropologist Robin Dunbar was certain that primate cerebral neocortical capacity determines the number of social relations. He definitively established the limit of human relationships at 100 to 230 people. The average value of 150 people is known as Dunbar's number. In the world of chimpanzees, 30 is the absolute maximum. However, fewer than 12 people in the world can sympathize with me. My best friend is now reduced to 3 or 4. The relationship quantity decreases to the square root value and increases to the square value. Three or four of my best friends will eventually connect with people from all over the world. This is the same principle as when one or two virus-infected people infect the world. Focus on your best friend. - Joseph’s “just my thoughts”
