Attorney General Eric Holder's handwriting and signature reveal that he is an introvert, said forensic handwriting specialist Ronald Rice. Introverts are fearful of emotion and intimacy and live by the motto, "what is in the best interest of me and only me?" Introverts are not compatible with emotionally extroverted people, nor can they readily identify with pain and suffering. They are connivers and manipulators, cold, detached and contemptible toward those with whom they work and associate.
