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?
I think some of this is also just that pop science often lags years or decades behind real science. Most people couldn’t name another famous psychologist, or an evolutionary scientist beyond Darwin, or a physicist beyond Einstein.
Specifically regarding art and philosophy, even if Freud’s idea were wrong, you can still glean something useful (or at least interesting) from using them as a starting premise.
