There were some serious negative consequences of this shift. The most obvious negative consequence was that a limited interpretation of Freud's theory of infantile sexuality would cause some therapists and others to deny reported sexual abuse as fantasy; a situation that has given rise to much criticism (e.g. "The Freudian Coverup" by social worker Florence Rush). However, without the rejection of the seduction theory, concepts such as the unconscious, repressions, the repetition compulsion, transference and resistance, and the unfolding psychosexual stages of childhood would never have been added to human knowledge.
