Which term describes believing something that is not based in reality?

• A. Hallucination
• B. Delusion
• C. Illusion
• D. Perception

Answer: (B)

Believing something that isn’t based in reality is a delusion. A delusion is a fixed, false belief held with strong conviction even when there’s clear evidence to the contrary and it isn’t explained by culture or education. It’s different from a hallucinatory experience, which is sensing something that isn’t there at all, and from an illusion, which is a misperception of a real stimulus. Perception is the processing of real sensory information, not a belief about reality.
