Perhaps this is off topic (sorry, I'm only new...) but...
I am puzzled by the tendency for people to put things into two categories "Science = useful" and "Non-science = Load of rubbish" is it possible for something to be non-scientific and still useful?
To me, whether psychology/psychiatry is science or not is really irrelevant, I find it a useful and live-preserving thing for me and that's really all that matters to me.
I personally don't think that Psychology SHOULD be a science.
