Someone asked me this question on a public forum site
I would like to share my answer
Before I answer this question, let me tell you a scientific story. The stories about the established treatment of Peptic Ulcer.
up until 1984 peptic ulcer was treated with antacids and then later proton pump blockers. If that didn’t work, we used surgery to cut the affected part away.
In 1984 a Canadians medical student Dr. Marshal by Pure serendipity discovered H. pylori bacterium, and thought that was what was causing the peptic ulcer disease. No one believed him so to prove his point he grew H. pylori and drank a potion made of the same and developed peptic ulcer in the bargain
Now the established treatment is a course of antibiotic
My question to you would be would you have not considered medicine as an inept science given that history?
Let’s tackle your question.
The theories and the treatments in psychiatry are like this. They are given to revision and modification.
Sigmund Freud was pioneer in Alerting the cause of many of the psychiatric symptoms could be in unconscious
Fast-forward few decades later-People like Eric Kendall, who by the way, got a Nobel prize the only Psychiatrist who ever received This honor -Did this seminal study in Aplysia a single cell animal?-to demonstrate the neurochemical basis of learning
So to answer your question, no I do not think psychiatry an inept science . Yes, it is destructive in a deconstructive sense that it explodes the myths around behavior, learning ,emotions and so on.
