Pathological fixation – preoccupation with a person or a cause that is accompanied by deterioration in social and occupational functioning – has been found to precede most cases of targeted violence. It is clinically observed and theorized to have three different cognitive‐affective drivers: delusion, obsession, or extreme overvalued belief. Each driver is explained, and case examples are provided in the context of threat assessment. Extreme overvalued belief as a new concept is discussed in detail, both its historical provenance and its demarcation from delusions and obsessions.
