The group syntality concept of Raymond B. Cattell furnishes a useful framework for teaching parliamentary procedure. Although there are contrasts between the histories, subject matters, and perspectives of the areas of parliamentary procedure and group dynamics, teachers and students of parliamentary procedure might profitably draw from some of the research and concepts associated with group dynamics. Cattell's theory may be used by parliamentary procedure teachers to provide an understanding of group syntality, which consists in large part of synergy (the total amount of energy that a group brings to bear on its activities), and to offer a perspective on leadership--any behavior that influences group syntality. Teachers can point out such obstacles to effective group decision making as inadequate preparation, hasty decision making, prolonged or imbalanced discussion, insufficient group cohesiveness, and the phenomenon of "groupthink," as discussed by Irving L. Janis, in which groups fail to consider the full range of options available to them in making decisions. The group syntality perspective provides an effective framework for integrating parliamentary rules and relevant principles of group dynamics and also heightens the responsiblity of individual group members.
