Development
While the definitions of delusion and obsession are familiar to most psychiatrists, overvalued ideas are less known, but are a key aspect of phenomenology in understanding eating disorders, some suicides, vexatious litigants, terrorists, and mass shooters. Abnormal fixations are experienced as normal by the individual because their reasoning is rational within their belief system (often a depraved subculture). Fixations such as these typically begin as a grandiose fantasy which then progresses to a lethal ideology analogous to the way eating disorders begin as a fantasy of becoming more thin and attractive, yet progresses to emaciation and even death. A school shooter or assassin might fantasize about becoming attractive to others through instant fame and notoriety. This fame is contagious due to a well known "copy cat" phenomenon fueled through media posts in digital subcultures. For this reason, Dr. Rahman waits at least 30 days after an attack event before he grants media interviews-- arguing that all mental health providers should resist immediate media coverage to reduce this violence contagion.
Overvalued ideas have been described in the psychiatric literature for well over 125 years. An extreme overvalued belief is a fixation that is shared by others in a person’s cultural, religious, or subcultural group. The belief is often relished, amplified, and defended by the possessor of the belief and should be differentiated from an obsession or a delusion. The belief grows more dominant over time, 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.
