Some things cannot be objectified nor empirically validated, but that does not mean they are not real nor valuable nor effective; I feel really ambivalent about saying this as, years ago, I would have immediately dismissed anyone who spoke this way.
Not every kind of therapy has (and may never have) evidence to support it in the ways some people on this board require them to. For example, in some forms of therapy, if you attempt to objectify an individual's experience so you can measure it, then you have completely undone all previous psychotherapeutic work (e.g. validating one's experiences as meaningful regardless of others' judgement of it). Points like this could be belabored on and refuted ad nauseum - and to what end?
I have come to see that some things need to actually be experienced to be understood, and so it is of no use to anyone to argue about it, which I think is what
Buzzwordsoldier was alluding to.
"Who cares" indeed.
