A delusion is a false fixed belief that is not amenable to change in light of conflicting evidence, it is distinct from a belief based on false or incomplete information.
A delusion is a fixed, false belief in something that is not real or does not exist, and is held despite evidence to the contrary.
A delusion is an unshakable belief in something that is untrue. The belief isn’t a part of the person’s culture or subculture, and almost everyone else knows this belief to be false.
