Anti-social personality disorder is VERY different from asocial personality traits or Cluster A personality disorders.
ASPD typically are angry, hostile, threatening, and demanding . . . damn sounds like T.x........ Anyway, usually before age 15 they are aggressive against people, cruelty to animals, setting fires, destroying property, deceitful (juvenile delinquent). After 15 they tend to violate the law, continue lying, deceit evolves in to con games as they learn to lie for a purpose (personal gain/revenge), impulsive, irritable often to the point of fights, general disregard for their safety and that of others, and often lack remorse for actions.
You have to be 18yo to get a formal diagnosis of ASPD. And yes our prison system has a bunch. Many people may have traits consistent with ASPD but it is a cluster of these traits and dysfunction in social, vocational, academic life that establishes a diagnosis.
Geeks are more likely Schizoid (detached, lack enjoyment from social relations, prefers social isolation, celibate, aloof from praise or criticism, emotionally restricted) or Schizotypal (paranoid, odd beliefs and thought patterns, unusual perceptions or speech, constricted affect - the outward appearance of their mood varies little with situations, eccentric behavior, lack of close friends, and excessive social anxiety. So Schizoids don't like other people, Schizotypals are odd so other people don't like them.
