Gordon's belief that each story contains a special, top-secret message for him is an example of a delusion of reference.
What is Delusion of Reference?
Delusions of reference are a type of false belief in which a person believes that unrelated events or objects have a special meaning or significance for them. In Gordon's case, he believes that the news anchors are deliberately sending him coded messages through their reporting.
Delusions of reference can be a symptom of a number of mental health conditions, including schizophrenia, bipolar disorder, and obsessive-compulsive disorder. They can also be caused by drug use or certain medical conditions.
