Many group-level constructs are based on within-group homogeneity in attitudes, affect, beliefs, and perceptions. In this article, three models for the development of within-group homogeneity are delineated. These models are shown to have implications both for differences between variables in their level of homogeneity and the conditions under which relatively high and low homogeneity should be observed. The models are explored in a small sample (N = 24 groups), where homogeneity in job satisfaction, positive affect, potency beliefs, and task-identity perceptions is examined. The results indicate that variables differ in their mean level of homogeneity and suggest that homogeneity may be the product of a combination of processes. A hierarchical framework for the investigation of homogeneity is suggested for further research.
