Most psychologists don’t care about Freud’s work outside of a historical sense and kinda hate him as a person. His work was quite literally used as an example of pseudoscience by Karl Popper.
And yet for some reason philosophers have an obsession with integrating his views into their work and artists keep using his views as inspiration and analyze existing works via the lens of psychoanalysis.
Why?
This gets at the history of literary and art theory in the 20th century. The basic answer is that people in the arts adopted psychodynamic frameworks from Freud, Lacan, etc, while actual psychologists moved on.
