If someone knowingly holds a false belief and expects others to affirm that it is true, it may not be classified as a delusion in the strict psychological sense. Delusions are characterized by a genuine belief in something that is not based in reality, and the person experiencing them is not aware that the belief is false. Delusions are typically seen in conditions like schizophrenia, delusional disorder, or certain forms of bipolar disorder.
However, expecting others to affirm something that is known to be false could indicate other psychological or social dynamics at play. It might be a form of manipulation, a desire for validation or attention, or a way to exert control over others. Such behavior could be indicative of other psychological issues or personality traits, and it may be essential to consider the broader context in which this behavior occurs.
If someone consistently presents false information while being aware of its falseness and demands that others affirm it as true, it could be a sign of a different psychological issue, such as a personality disorder or a need for validation and attention.
In any case, understanding the underlying reasons for this behavior would require a comprehensive evaluation by a qualified mental health professional. They can assess the individual's mental health and provide appropriate support or treatment if necessary. It's important not to jump to conclusions or make a diagnosis without proper expertise and evaluation.
