“Even if all interested parties only want symptom relief, ignoring the cultivation of wisdom may still be a problem. Focusing exclusively on empirically supported techniques runs the risk of failing to develop the primary instrument of treatment—us. Even as much of the therapy literature, modeled after double-blind pharmaceutical research, has tried to eliminate the therapist as a variable, metanalyses like those of Bruce Wampold and others keep showing that we can’t take ourselves out of the equation. Again and again, we learn how much the therapeutic relationship matters.”
