 Psychology is not totally a scientific study, because if you think deeply about the theory of S.Freud about Ego, Super Ego, and Id, which have not been proven by scientific methods. As scientists believe seeing is believing, but S. Freud had never seen these three essences, and how he discovered them is not clear up until now. He also refutes human beings free will, if we do not own a free will, how can we make decisions? I think the psychologists have to reconsider S.Freud's theories about his psychoanalysis and find out about the true identification of human beings.
