I once spent hundreds of hours looking at a film of a family therapy session. And there was a mother and a father and the child who was the identified patient and a psychotherapist. And that child was a bizarre behavior, disruptive, just and I thought, oh, that child is making his parents miserable. What an awful thing. And then after I watched it another hundred times, I thought, you know, it's that mother that's making the child behave that way. Another hundred times, and I thought, and now father's sitting there, you think he's not doing anything. He's the one that's causing all the trouble. And then eventually I thought, you know, I think it might be the psychotherapist. The point being that the pathology was not in the child or the mother or the father or the therapist. It was in the system. It was in the relationship, the pattern of relationship between them. And I was trying to attach it to an individual, which is the way we are trained to think about causation.
