I've found in my research there is a great deal of quantifiable data pertaining to different therapy practices and outcomes and that some of it is measured with concrete metrics as sound as in any science whether it be physics, medicine, geology, etc.

I mean, here's a random meta-analysis.

It's evident to me that a great deal of time, thought and expertise went into the format and construction of this research which was in turn analyzing, distilling and building on findings from numerous other studies.

This isn't my 'city on a hill' study- it's not an ultimate document, just a handy one online among a vast number in a body of knowledge that was built during the past century-plus using the best scientific methods of all disciplines. You'll find the same processes in many of these studies as in those areas (and the same jargon).

There are certainly tens of thousands of studies on all types of therapy related topics, from mental illnesses like depression, bpd and numerous others to the efficacy of different types of therapy, to the role of other factors like relationship, to the challenges of therapy with constraints due to varying healthcare systems and other impediments.

I'm not sure what it really means "there is no real science behind it".

I do understand that in all disciplines, the findings can develop over time, not only in psychotherapy but in mathematics, astronomy, biology. So, the fact that there is scientific research surely doesn't mean we all have an easy way out of our mental health issues. I don't think we've found the all-purpose aspirin of psychic pain either in talk therapy or drug therapy. Nor do I believe science has all the answers, or that there isn't more of value in therapy than can be measured, just as I wouldn't care to have falling in love left only to a measure of how my heart rate increases or the labels of the hormones released when I feel it.

But it's not black and white.

P.S. I was in a study (about the PTSD), and I was not dehumanized. I appreciated getting to participate and I appreciated the respect with which the process was done.
