This chapter addresses regressive groups. From the perspective of chaos theory, these groups are stuck in limit cycles. They do the same things over and over again. The group must, of course, endure chaos if it is to develop. However, regressive groups have not developed sufficient fixed points to which they might anchor to contain themselves as they experience the anxi ety and upheaval necessary for reorganization to the next stage of devel opment. The group shuts down, limiting energy exchange or feedback from other systems. As the group becomes more isolated, opportunities for constructive reorganization decrease. The limit cycle or back-and-forth motion of the pendulum characterizes the group’s movement as novelty is damped.
