J.J. Gittes Personality Type, MBTI

J.J. Gittes personality type is ISTP, an Introverted Sensing Thinking Perceiving person. That means that he uses facts and data to make decisions, and he is a very practical guy. He uses his intuition to come up with the best possible solution, but if he dislikes something (which is not infrequent), he will not allow himself to get swayed by emotions. He is not afraid to act on instinct, but if he finds out that what he does is wrong, he will immediately acknowledge it and make the necessary changes to make things right again.
