Capgras delusion is a misidentification phenomenon where a person believes a familiar individual, commonly a family member, has been replaced by an identical impostor. In case series, this manifests as the patient not recognizing their own family as the real person, insisting that the familiar face is an impostor rather than their true relative. This reflects the core feature: recognition feels off even though the person looks the same, leading to a belief of substitution. Therefore, the statement that the majority did not recognize their own family best captures the typical observation. The other options don’t fit because Capgras is not defined by universal violent behavior, and misidentification of relatives is, in fact, a hallmark of the condition.
