In Freudian psychology, displacement (German: Verschiebung, "shift, move") is an unconscious defense mechanism whereby the mind substitutes either a new aim or a new object for goals felt in their original form to be dangerous or unacceptable.
A term originating with Sigmund Freud, displacement operates in the mind unconsciously, its transference of emotions, ideas, or wishes being most often used to allay anxiety in the face of aggressive or sexual impulses.
Freud initially saw displacement as a means of dream-distortion, involving a shift of emphasis from important to unimportant elements, or the replacement of something by a mere illusion.
Freud also saw displacement as occurring in jokes, as well as in neuroses – the obsessional neurotic being especially prone to the technique of displacement onto the minute. When two or more displacements occurs towards the same idea, the phenomenon is called condensation (from the German Verdichtung).
Among Freud's mainstream followers, Otto Fenichel highlighted the displacement of affect, either through postponement or by redirection, or both. More broadly, he considered that "in part the paths of displacement depend on the nature of the drives that are warded off".
Eric Berne in his first, psychoanalytic work, maintained that "some of the most interesting and socially useful displacements of libido occur when both the aim and the object are partial substitutions for the biological aim and object...sublimation".
In 1957, Jacques Lacan, inspired by an article by linguist Roman Jakobson on metaphor and metonymy, argued that the unconscious has the structure of a language, linking displacement to the poetic function of metonymy, and condensation to that of metaphor.
