The test at
http://www.4degreez.com/misc/personality_disorder_test.mv says I am Schizotypal and Narcissistic.
I just read a study that indicates narcissism is 75% heritary. Hrm...
Their definitions are as follows...
Schizotypal
Many believe that schizotypal personality disorder represents mild schizophrenia. The disorder is characterized by odd forms of thinking and perceiving, and individuals with this disorder often seek isolation from others. They sometimes believe to have extra sensory ability or that unrelated events relate to them in some important way. They generally engage in eccentric behavior and have difficulty concentrating for long periods of time. Their speech is often over elaborate and difficult to follow.
Narcissistic
Narcissistic personality disorder is characterized by self-centeredness. Like histrionic disorder, people with this disorder seek attention and praise. They exaggerate their achievements, expecting others to recognize them as being superior. They tend to be choosy about picking friends, since they believe that not just anyone is worthy of being their friend. They tend to make good first impressions, yet have difficulty maintaining long-lasting relationships. They are generally uninterested in the feelings of others and may take advantage of them.
