Group cohesiveness has been defined in many ways, with no general consensus regarding how to define the term, despite a relatively long history of attempting to reach such a consensus (Yalom, 1985). Leon Festinger (1957) defined the concept in terms of forces that lead an individual to remain in or leave a given group. Credited with developing the concept of cognitive dissonance, a theory that recognizes and, more importantly, explains how individuals become invested in ideas and strongly motivated to maintain those intellectual investments, Festinger and his many students and colleagues contributed much to our understanding of why and how individuals create and maintain groups as well as what causes those groups to fragment. He and others interested in the psychology of groups have taught us that an understanding of group psychology is as important as the study of individual psychology if we wish to fully understand human behavior.
