Research consistently shows that the psychotherapeutic relationship matters more than a particular technique.
How therapists show up—their presence, voice, body, and responsiveness—is as important as interventions.
Actors can show therapists how to be present, adapt, and invite clients into connection and possibility.
Psychotherapy research is both illuminating and humbling. After a century of developing theories, modalities, evidence-based treatments, and “best practices,” we keep returning to the same fact:
The effectiveness of therapy depends not on any particular technique, but on the individual therapist, the individual client, and “the unique patterns of interaction that develop between them” (Shedler, 2012).
While a wide range of therapy models have proven to be helpful for specific people at specific times, studies show that it doesn’t necessarily matter whether a therapist practices ACT, CBT, DBT, EFT, EMDR, or psychoanalysis. What matters is how the two people in the room engage one another (Shedler, 2012; Stendi & Matos, 2023; Cruwys et al., 2023).
A recent New York Times article about our endless search for a one-size-fits-all psychotherapy approach emphasizes this point. The author, Daniel Duane, brilliantly provides thorough, cogent, and accessible context for how the therapy conversation has evolved and expanded over the years, and what remains consistent: the primary importance of the therapeutic relationship (Duane, 2026).
Duane concludes by introducing predictive processing, a neuroscience-based theory that explains why clients tend to protect themselves from vulnerability and change, and how the therapist/client relationship has the potential to free people from these patterns, no matter what technique is used (Corlett et al., 2020).
Predictive processing certainly helps explain why the unique relationship is in fact what matters most in psychotherapy. And yet, despite his attempt to do the opposite, Duane can’t entirely resist the very quest for a unifying psychotherapy theory that it intends to critique.
Is there truly a way out of this dilemma?
Rather than attempting to find one convincingly rigorous approach to therapy, what if we simply let the research speak for itself?
What if we accepted that what therapists and researchers all tend to agree on actually matters—that how a therapist engages a particular client matters more than which intervention they use? Even iconic CBT therapist Judith Beck believes the........
