The Meyers-Briggs Personality Test is based on Jung's analytical psychology. This man was evil from a Christian standpoint. His idea for personality types did not come from God, but from principalities. In a séance he communicated with a twelve-years old girl who instructed him in his thought processes. His "individualism"concept is the key to personality in his viewpoint. Much of this came to Jung from Christianity, Hinduism, Buddhism, Gnosticism and Taoism. In other words what he presents as "science" is no more than eastern religion, oriental thought and Christian heresy!
