Delusions

« Back to Glossary Index

Delusions are beliefs held despite evidence to the contrary. They are often systematized into organized patterns of irrational thought, but they need not be. The term delusion is used in psychiatry to describe a belief, the content of which is significantly out of touch with both reality and the individual’s cultural norms.

The key feature of a delusion is the degree to which the belief is held with conviction. The person experiencing a delusion will hold firmly to the belief with an unwavering conviction that does not waiver. Delusions are not based on reality and are not based on actual experiences but rather on false information (e.g., hallucinations) or incorrect inferences drawn from normal experiences.
