The sensation of belonging to a group and generally feeling connected to other individuals is what academics mean when they talk about the idea of social connection. There is substantial scientific evidence that this is a fundamental psychological need that is necessary for life satisfaction.
The need to interact with others is ingrained in our biology and evolutionary history, proving that humans are a highly social species. It starts with our bond with our caretaker at birth, and the consequences of that relationship appear to last a lifetime. Having stable, healthy bonds as we age is more likely when we were well-cared for as children.
Furthermore, the pleasures of social interaction register in our brains similarly to physical pleasure, and our innate ability to connect with others is evident in some of the simplest ways that people communicate, such as through subtle body language, facial expressions, and touch. Because natural selection favors individuals with a higher predisposition to care for their kids and form into communities, scientists believe that humans are fundamentally built to interact with others.
