What type of beliefs are characteristic of fixed false beliefs?

Fixed false beliefs are characterized by delusions. Delusions are defined as strongly held beliefs that are not based in reality and remain consistent despite evidence to the contrary. They are a common symptom in various psychiatric disorders, such as schizophrenia, delusional disorder, and some mood disorders with psychotic features.

These beliefs can take various forms, including paranoid delusions (believing one is being persecuted), grandiose delusions (believing one has exceptional abilities or fame), and somatic delusions (believing one has a medical condition despite no evidence). The key feature of these beliefs is their persistence and the individual's unwavering conviction in them, even when presented with contrary information.

Disorganized thoughts refer to a disarray in thought processes that may manifest as incoherent speech or difficulty in organizing thoughts, but these do not specifically pertain to fixed beliefs. Illusions are misinterpretations of real external stimuli, and hallucinations involve perceiving things that are not present at all (like seeing or hearing things that do not exist), neither of which represent fixed false beliefs.
