Wikipedia
A delusion is a fixed belief that is either false, fanciful, or derived from deception. In psychiatry, it is defined to be a belief that is pathological (the result of an illness or illness process) and is held despite evidence to the contrary. As a pathology, it is distinct from a belief based on false or incomplete information, dogma, stupidity, apperception, illusion, or other effects of perception.
