Good morning @slowgrow
Just in case you are interested in my point of view please take a look at this post I wrote a while back: Is psychology a science? The post does not cover all the angles a discussion like this could/should go into, but it's a good start. Nevertheless, many of those angles were brought up and debated throughout the comment feed. Further, I would like to point out that psychology goes way beyond the field of clinic work and diagnosis. But, I suspect you already know this :)
Best,
Abigail
