Seems to me therapy as a practice encourages attachment, and what individual therapists do is secondary. Even a robotic therapist with "good boundaries" is encouraging dependency by orchestrating such an asymmetrical and potentially regressive relationship. Plus a walled off therapist is liable to induce obsessive fixation in the client as they try to figure out who is this cipher.

The main point to me is that therapists have little or no control over how a client will respond. I mean, do they think they can flowchart some sort of therapy attachment process?
