According to Hubbard, suppressive persons have a number of distinct characteristics:
1. He or she speaks only in very broad generalities.
2. Such a person deals mainly in bad news, critical or hostile remarks, invalidation, and general suppression.
3. The antisocial personality alters, to worsen, communication when he or she relays a message or news. Good news is stopped and only bad news, often embellished, is passed along.
4. A characteristic, and one of the sad things about an antisocial personality, is that it does not respond to treatment or reform or psychotherapy.
5. Surrounding such a personality we find cowed or ill associates or friends who, when not driven actually insane, are yet behaving in a crippled manner in life, failing, not succeeding.
6. The antisocial personality habitually selects the wrong target.
7. The antisocial personality cannot finish a cycle of action.
8. Many antisocial persons will freely confess to the most alarming crimes when forced to do so, but will have no faintest sense of responsibility for them.
9. The antisocial personality supports only destructive groups and rages against and attacks any constructive or betterment group.
10. This type of personality approves only of destructive actions and fights against constructive or helpful actions or activities.
11. Helping others is an activity which drives the antisocial personality nearly berserk. Activities, however, which destroy in the name of help are closely supported.
12. The antisocial personality has a bad sense of property and conceives that the idea that anyone owns anything is a pretense, made up to fool people. Nothing is ever really owned.
