Answer:
Delusion
Explanation:
In psychology, the term delusion makes reference to a rigid system of beliefs with which a person is preoccupied despite the logical absurdity of the beliefs and a lack of supporting evidence. In other words, it is a belief that has no logical support or evidence to it but that the person firmly believes.
In this example, Tania believes that the CIA is trying to control her thoughts and she has put aluminum foil over the windows to block the rays she thinks the CIA is beaming into her brain. We can see that Tania firmly believes that the CIA is trying to control her thoughts although this belief is absurd and there is no logical supporting evidence to this thought. Therefore, Tania's fixed false belief is known as a delusion.
