I suspect therapy methods work better the more you believe in and trust them. This means there's something harmful about studying how well therapy methods work and publicizing that information, which is that they can cause the methods to work less well.

Feeling trust and hope in a therapy method is not a purely mental phenomenon, separated from the world. It has very real physical effects in your body; your autonomic nervous system is doing stuff, your muscle tension is doing stuff, etc.

Inspiration is actually healing; lack of inspiration may make the difference between a therapy method (or whatever else) making progress or not. That's not something I used to appreciate at all.

Above for "therapy method" one can also substitute "spiritual path." This stuff seems to get super complicated. Still pondering all this.

Another documented example of this with lots of evidence is willpower depletion. 1. Willpower seems to be a limited resourced. 2. If you believe willpower is unlimited, you have more of that limited resource.
