What characterizes a delusion of grandeur?

Delusion of grandeur is characterized by an exaggerated belief about one's importance, wealth, power, or talents. Individuals experiencing this type of delusion often have a distorted sense of self-worth and may believe they have extraordinary abilities or achievements that are not grounded in reality. This can manifest as claims of being influential figures, possessing special skills, or holding high status in society that is not reflective of their actual life circumstances.

In contrast, the other options describe different types of beliefs or delusions. A belief that one has no value pertains to feelings of worthlessness or nihilism, which is not indicative of grandeur. A belief in being persecuted reflects paranoia rather than an inflated self-view. Lastly, a belief in supernatural abilities could qualify as a separate delusion, depending on its presentation, but does not adequately encompass the broader definition of grandeur, which is specifically tied to an inflated perception of oneself in terms of importance or status.
