Belongingness is the human emotional need to be an accepted member of a group. Whether it is family, friends, co-workers, a religion, or something else, people tend to have an 'inherent' desire to belong and be an important part of something greater than themselves. This implies a relationship that is greater than simple acquaintance or familiarity. The need to belong is the need to give and receive attention to and from others.

This implies a relationship that is greater than simple acquaintance or familiarity. The need to belong is the need to give and receive attention to and from others. Belonging is a strong and inevitable feeling that exists in human nature. To belong or not to belong can occur due to choices of one's self, or the choices of others. Not everyone has the same life and interests, hence not everyone belongs to the same thing or person. Without belonging, one cannot identify themselves as clearly, thus having difficulties communicating with and relating to their surroundings. Roy Baumeister and Mark Leary argue that belongingness is such a fundamental human motivation that we feel severe consequences of not belonging. If it wasn’t so fundamental, then lack of belonging wouldn’t have such dire consequences on us. This desire is so universal that the need to belong is found across all cultures and different types of people. Abraham Maslow suggested that the need to belong was a major source of human motivation. He thought that it was one of 5 human needs in his hierarchy of needs, along with physiological needs, safety, self-esteem, and self-actualization. These needs are arranged on a hierarchy and must be satisfied in order. After physiological and safety needs are met an individual can then work on meeting the need to belong and be loved. According to Maslow, if the first two needs are not met, then an individual cannot completely love someone else. Other theories have also focused on the need to belong as a fundamental psychological motivation. According to Roy Baumeister and Mark Leary, all human beings need a certain minimum quantity of regular, satisfying social interactions. Inability to meet this need results in loneliness, mental distress, and a strong desire to form new relationships. Several psychologists have proposed that there are individual differences in people's motivation to belong. People with a strong motivation to belong are less satisfied with their relationships and tend to be relatively lonely. As consumers, they tend to seek the opinions of others about products and services and also attempt to influence others' opinions. According to Baumeister and Leary, much of what human beings do is done in the service of belongingness. They argue that many of the human needs that have been documented, such as the needs for power, intimacy, approval, achievement and affiliation, are all driven by the need to belong. Human culture is compelled and conditioned by pressure to belong. The need to belong and form attachments is universal among humans. This counters the Freudian argument that sexuality and aggression are the major driving psychological forces. Those who believe that the need to belong is the major psychological drive also believe that humans are naturally driven toward establishing and sustaining relationships and belongingness. For example, interactions with strangers are possible first steps toward non-hostile and more long-term interactions with strangers that can satisfy the need for attachments. Certain people who are socially deprived can exhibit physical, behavioral, and psychological problems, such as stress or instability. These people are also more likely to show an increase in aiming to form new attachments. In all cultures, attachments form universally. Social bonds are easily formed, without the need for favorable settings. The need to belong is a goal-directed activity that people try to satisfy with a certain minimum number of social contacts. The quality of interactions is more important than the quantity of interactions. People who form social attachments beyond that minimal amount experience less satisfaction from extra relationships, as well as more stress from terminating those extra relationships. People also effectively replace lost relationship partners by substituting them with new relationships or social environments. For example, individuals with strong family ties could compensate for loneliness at work. Relationships missing regular contact but characterized by strong feelings of commitment and intimacy also fail to satisfy the need. Just knowing that a bond exists may be emotionally comforting, yet it would not provide a feeling of full belongingness if there is a lack of interaction between the persons. The belongingness hypothesis proposes two main features. First, people need constant, positive, personal interactions with other people. Second, people need to know that the bond is stable, there is mutual concern, and that this attachment will continue. So, the need to belong is not just a need for intimate attachments or a need for connections, but that the perception of the bond is as important as the bond itself. Individuals need to know that other people care about their well-being and love them. Baumeister and Leary argue that much of the research on group bonds can be interpreted through the lens of belongingness. They argue that plenty of evidence suggests that social bonds are formed easily. In the classic Robber's Cave study, stranger boys were randomly grouped into two different groups and almost immediately, group identification and strong loyalty developed to their specific group. Initially, the two groups were asked to compete with one another, and hostility between the groups ensued. However, when the two groups were combined to form one big group and were given the opportunity to bond by working together to accomplish superordinate goals, behaviors and emotions accommodated quickly to that new group. In an attempt to understand causes of in-group favoritism, researchers formed a group so minimal and insignificant that one would expect that no favoritism would be found, yet in-group favoritism appeared immediately. Researchers agree that banding together against a threat (the out-group) and sharing rewards are primary reasons groups form and bond so easily. Mere proximity is another powerful factor in relationship formation. Just like babies form attachments with their caregivers, people develop attachments just because they live near one another. This suggests that proximity sometimes overcomes the tendencies to bond with others who are similar to us. Positive social bonds form just as easily under fearful circumstances, such as military veterans who have undergone heavy battle together. This can be explained by either misattribution (interpreting feelings of anxious arousal as feelings of attraction for another person) or reinforcement theory (the presence of another person reduces distress and elicits positive responses). Baumeister and Leary argue that the reinforcement theory explanation provides evidence for the importance of belonging needs because these learned associations create a tendency to seek out the company of others in times of threat. The formation of social attachments with former rivals is a great indicator of the need to belong. Belonging motivations are so strong that they are able to overcome competitive feelings towards opponents.
