Psychoanalysts claim that our behavior is automatic because our mind is "10% conscious and 90% unconscious." Dr. Carl Gustav Jung, Swiss founder of analytic psychology, emphasized the role of the "unconscious" even more than psychoanalyst Dr. Sigmund Freud. He wrote the book "Psychology of the Unconscious." Dr. Jung's theory of the unconscious explains types of personality such as either introverted or extroverted by looking at the development of 4 functions: sensing, thinking, intuiting, and feeling. One of the most popular personality tests today used in diagnosis and therapy, Myers-Briggs Type Indicator, is based on Dr. Jung's theory.
"Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will." (Romans 12:2)
