We'd had a very bad experience in training in the early mid-70s in Northern Ireland, where a couple of groups had come over from the United States, I'm afraid. They are very intense, very difficult groups with a lot of the community folk in Northern Ireland. They left without debriefing and left a lot of sorrow behind, a lot of distrust about group techniques. It was basically using a tavis doc technique, people couldn't really understand large group stuff, and that in a way, put people off group work.
