| - An extreme overvalued belief is shared by others in a person's cultural, religious, or subcultural group (including online). The belief is often relished, amplified, and defended by the possessor of the belief and should be differentiated from a delusion or obsession. Over time, the belief grows more dominant, more refined, and more resistant to challenge. The individual has an intense emotional commitment to the belief and may carry out violent behavior in its service. Over time, belief becomes increasingly binary, simplistic, and absolute. (en)

| - An extreme overvalued belief is shared by others in a person's cultural, religious, or subcultural group (including online). The belief is often relished, amplified, and defended by the possessor of the belief and should be differentiated from a delusion or obsession. Over time, the belief grows more dominant, more refined, and more resistant to challenge. The individual has an intense emotional commitment to the belief and may carry out violent behavior in its service. Over time, belief becomes increasingly binary, simplistic, and absolute. The description was first proposed by a group of forensic psychiatrists led by psychiatrist Dr. Tahir Rahman at Washington University in St. Louis in response to an analysis of the insanity trial of Anders Breivik, a Norwegian terrorist responsible for the massacre of 77 people, mostly youth, in Oslo and Utoya, Norway, in July 2011. Extreme overvalued beliefs can be the cognitive-affective drivers of a pathological fixation – preoccupation with a particular person or cause that is accompanied by deterioration in social and occupational functioning. Fixation is a very frequent proximal warning behavior in targeted attacks where violence is planned, purposeful, and predatory. Although fixation is not a predictor of such attacks, its frequency—typically occurring in four out of five cases—across a variety of domains of targeted attackers prior to their actions provides support for its use as a correlate of such behavior.
