Psychology is not falsifiable and therefore not a science.
That's why you can have multitudes of wildly conflicting theories and schools of psychotherapy, where most of them work to achieve the goal of wellbeing, but none of which achieve understanding of how human brain works. (of course, some pretend they do, and try to portray this to the patients - as if the ideology the school of therpay holds is the truth about the human brain)
There's nice discussion of this in the book "Health & Suffering in America by R. T. Fancher"
There's not yet a Wikipedia page for "Computational Psychiatry". I guess that very definable category of psychiatry doesn't like to publish.
Are transference and countertransference of traits like extraversion a result of the (indeed widely varying) therapeutic methods or the result of just spending some quality time together rewarding self-focus and insight?
There may be some quantifiable rejections of guesstulative models of cognition (and personality!) available due to advances in neuroimaging which are enabling computational neuroscience (which does have a Wikipedia page for it)
Computational neuroscience: https://en.wikipedia.org/wiki/Computational_neuroscience
> Computational neuroscience (also known as theoretical neuroscience or mathematical neuroscience) is a branch of neuroscience which employs mathematical models, theoretical analysis and abstractions of the brain to understand the principles that govern the development, structure, physiology and cognitive abilities of the nervous system.

> As James Lawley and Penny Tompkins describe it, Grove realized many clients were describing their symptoms in metaphors drawn from the exact words of previous therapists, instead of from their own experience
There, that should help with the disinhibition and extraversion.
The book is mostly about historical context of psychological treatment in america and a critique of when people in helping professions jump from "our techniques help people" to "therefore the theoretical basis for our techniques is the truth"
