Which delusion involves a fixed false belief that one is more powerful or important than one actually is?

• A. Delusions of persecution
• B. Delusions of reference
• C. Delusions of grandeur
• D. Capgras syndrome

Answer: (C)

The idea being tested is a fixed false belief that you are more powerful, famous, or important than you actually are. This is the delusion of grandeur, a classic grandiose belief that someone has extraordinary abilities or status despite evidence to the contrary. It often appears in psychotic disorders or during manic episodes. It differs from delusions of persecution (believing you’re being harmed or targeted), delusions of reference (believing ordinary events have special personal meaning), and Capgras syndrome (believing a familiar person has been replaced by an impostor).
