In 2011, Roy Baumeister furthered this notion of belongingness by proposing the Need to Belong Theory, which asserts that humans have an inherent drive to maintain a minimum number of social relationships to foster a sense of belonging. Baumeister highlights the importance of satiation and substitution in driving human behavior and social connection. Motivational satiation is a phenomenon in which an individual may desire something, but at a certain point, they may reach a point where they have had enough and no longer want or need any more of it. This concept can be applied to the formation of friendships, where an individual may desire social connections, but they may reach a point where they have enough friends and do not seek any more. However, Baumeister suggests that people still require a certain minimum amount of social connection, and to some extent, these bonds can substitute for each other. The Need to Belong Theory is a primary motivator of human behavior, providing a framework for understanding social relationships as a basic, fundamental need for psychological health and well-being.
