I am well aware that certain exercises, tasks setup by the facilitator, can practically force the group to more of a here-and-now communication or more of a feeling level. There are leaders who do these very skillfully, and with good effect at the time. However, I am enough of a scientist-clinician to make many casual follow-up inquiries, and I know that frequently the lasting result of such procedures is not nearly as satisfying as the immediate effect. At it's best it may lead to discipleship (which I happen not to like): "What a marvelous leader he is to have made me open up when I had no intention of doing it!" It can also lead to a rejection of the whole experience. "Why did I do those silly things he asked me to?" At worst, it can make the person feel that his private self has been in some way violated, and he will be careful never to expose himself to a group again. From my experience I know that if I attempt to push a group to a deeper level it is not, in the long run, going to work.
