How Important Are the Common Factors in Psychotherapy? An Update is a work by Bruce E. Wampold (2015).

Core claims

Wampold’s updated review confirms that common factors — the therapeutic alliance, therapist effects, empathy, expectations, and cultural adaptation — account for far more outcome variance in psychotherapy than specific technique factors, with common factors explaining approximately 40% of variance versus 1% for specific ingredients.
The paper demonstrates that therapist effects dwarf technique effects: the person delivering the treatment matters more than the treatment being delivered, a finding that fundamentally challenges the manualization movement’s assumption that therapy can be standardized and the therapist rendered interchangeable.
Wampold’s contextual model of psychotherapy positions all effective therapies as healing practices that operate through the creation of a therapeutic bond, the provision of an explanatory framework, and the enactment of health-promoting actions — a model that accommodates depth psychological approaches as readily as cognitive-behavioral ones.

Does Wampold’s finding that therapist effects overwhelm technique effects validate Jung’s insistence that the analyst’s own psychological development is the decisive factor in treatment outcome — and does it imply that the most important form of clinical training is personal analysis rather than technique acquisition?
How does the contextual model’s emphasis on explanatory frameworks relate to Hillman’s concept of ‘healing fiction’ — the idea that the therapeutic narrative’s truth lies not in its correspondence to reality but in its capacity to mobilize the patient’s self-healing capacities?
