“Today mathematical system theory is a rapidly growing field, but it is natural that basic problems […] are approached only slowly and presumably will need novel ideas and theories. “Verbal” descriptions and models are not expendable. Problems must be intuitively “seen” and recognized before...

I didn't see the term relational psychiatry here, although many of his ideas made me think of De Haan's Enactive Psychiatry (which I would call relational). Although I often think about Enactive Psychiatry, so that may just be me.

Go to your university library, search for old books (at least 50 years ago) on your research topic, find out that, in a way, everything is in it already.
Much recommended.

Wow, that's bad and crooked* of them to accuse you. They should reread your paper. Also, I find it very naive of them to think that you can just do science on nameless unspecified shared variance without making it a reality.

I couldn't follow the viewpoint when reading it - thanks for the clarification here. My 2 cents: I think reification is best understood as a sociological phenomenon: the language game around p. These authors make it a personal opinion/act - again distracting from possible consequences.

... and whether outlying values may signal recovery from perturbations. At least in these cases, they do, which means that non-stationarity and outlying values should not by default be regarded as methodological problems as they may signal meaningful and relevant phenomena worth studying.
