Several definitions of delusions have been advanced. Common features of these descriptions include the presence of a false belief or set of beliefs that fall outside of a person's cultural or subcultural values and are held with extraordinary conviction. The beliefs are held in spite of being unsubstantiated, in the face of evidence to the contrary, and/or in opposition to the beliefs of almost all others. Delusions are differentiated from other erroneous thoughts such as phobias and obsessions in that they are illogical, accepted by the individual as true, held with tenacity, and often implausible.
