Group cohesiveness

Group cohesiveness is the degree to which the members of a social group feel bound to one another and to the group as a whole, a concept researchers typically break into four linked parts: social relations among members, task relations built around shared work, a felt sense of group unity, and the emotions members associate with belonging to the group. Most accounts treat cohesion as a blend of commitment to the group's task and genuine interpersonal attraction among its members, and researchers describe it as multidimensional, changing over time, driven by the practical purposes the group serves, and emotionally rewarding in its own right. A key theoretical distinction separates ordinary personal liking from social attraction, warmth felt toward another member specifically because they seem to typify the group, rather than for their own individual qualities. Cohesion tends to rise when members share similar backgrounds, attitudes and values, when the group stays relatively small, when entry is difficult enough to make membership feel like an achievement, and when the group succeeds or faces outside competition, and it shapes outcomes across sports teams, military units, workplaces and fraternal organizations, improving motivation, performance, satisfaction and emotional adjustment, while also raising the risk of excessive conformity and groupthink.
