Which symptom is characteristic of schizotypal personality disorder?

Schizotypal personality disorder is characterized by eccentric behaviors and thought patterns that significantly deviate from social norms. One of the hallmark symptoms of this disorder is magical thinking, which involves believing in the influence of one's thoughts on external events or that one's thoughts can call upon supernatural forces. Individuals with this disorder may also engage in odd behaviors or exhibit peculiarities in their speech and appearance.

This symptomatology is distinct from other personality disorders; for instance, while avoidance of social situations can be common in avoidant personality disorder, it does not specifically reflect the unique traits of schizotypal disorder. Similarly, high levels of sociability would contradict the common social withdrawal seen in many personality disorders, including schizotypal. Severe mood swings are more characteristic of mood disorders than personality disorders. Therefore, the presence of magical thinking and odd behaviors is a defining feature of schizotypal personality disorder.
