In plain words
Displacement is sending a feeling to the wrong place. Anger at a boss is spent on a partner, a slammed door or a driver who cuts in. The anger is real and its source is unchanged, but the target is safer. The same word is used for a second process in dreams, where emotional weight moves onto something that seems unimportant.
Where the idea comes from
Freud introduced the term in his work on dreams. In The Interpretation of Dreams (1900; English by A. A. Brill, 1913), chapter VI on the dream-work describes "the work of displacement": emphasis shifts from important dream-thoughts to trivial elements, so the dream's central image may seem unrelated to its real concern. Freud attributes this disguise to a censorship between mental agencies. He extended the idea to waking life, and suggested, for instance, that children's animal phobias may displace fears of their parents.
Otto Fenichel (1946) emphasised displacement of affect. Anna Freud's work helped place it among the defence mechanisms, and in Vaillant's hierarchy it is a neurotic-level defence. Jacques Lacan (1957) linked displacement to metonymy and condensation to metaphor, as part of his argument that the unconscious is structured like language; that reading belongs to his school and is not widely shared outside it.
How it shows up
The common version is a chain: a person is criticised at work, says nothing, comes home and is sharp with someone who had no part in it. The tell is proportion. The reaction is larger than its trigger, and the person can often trace the real source once they slow down. In writing, the same thing can look like an extended complaint about something minor and a single flat sentence about the thing that mattered.
Oneli, the AI agent on TwentyThird, may ask what else was going on that day when a member's strongest feeling seems attached to a small event. It does not tell anyone what the real target is.
What it is not
It is not the same as projection, though the page on displacement notes an overlap in "displacement of attribution". Critics point out that the idea explains behaviour after the fact and does not predict it, which makes it hard to falsify. Experimental work on displaced aggression exists but was not reviewed for this entry, so no claim about its strength is made here.
