Obviously a person that prides oneself on finding the truth no matter what the personal implications. A Organ Heart for some personalized and raw eccentricity. But being a supposed INTJ I would think one to be slightly narcissistic and creates truth rather then observes truth. Hence your signature being such an eccentricity has it is unlike the common heart. A hyper intelligent ape? I'm guessing you fancy yourself as some kind of intellectual elect. As one that takes the theory of Darwin as truth. Perhaps this along with your creed of accuracy is a statement of superiority over what you perceived as bigoted close-minded religious people. Careful that narcissism can lead you in just as a close-minded state.
