It is not that science has no relevant things to say to psychology being as it is “science”, it is that “science” itself is a big beautiful fairy story, as is most of reality.
In psychology’s honourable striving to peel itself away from “science” it is preserving the notion that “science” is serious. Serious enough to peel from, or brush off, or expunge. Psychology does this to preserve the whole idea of revering seriousness….because it continues to want to keep its finger in that serious pie.
Psychology will never let “science” be myth. Because psychology does not want to seem like a thing of play.
Instead psychology will call “science” A SERIOUS THING that psychology needs to be seriously divorced from, because it is so serious, as is psychology serious.
