Psychoanalytic theory posits that an individual unable to integrate difficult feelings mobilizes specific defenses to overcome these feelings, which the individual perceives to be unbearable. The defense that effects this process is called splitting. Splitting is the tendency to view events or people as either all bad or all good. When viewing people as all good, the individual is said to be using the defense mechanism idealization: a mental mechanism in which the person attributes exaggeratedly positive qualities to the self or others. When viewing people as all bad, the individual employs devaluation: attributing exaggeratedly negative qualities to the self or others.
