Through the lens of the Striving Styles, each of the Myers-Briggs Type Indicator® (MBTI®) 16 Types comes alive. Discover which quadrant of the brain the INTP prefers to use and the predominant, innate psychological need that drives the INTP's behavior as well as how an INTP can leverage their whole brain in order to develop and achieve their potential. The SSPS shows that each of the four quadrants of the brain has their own role, or function, to play in our personality and our consciousness. Based on Jung's Theory of Psychological Type, we are hard-wired to prefer one function or quadrant over the others and we use each quadrant or function in either an inwardly or an outwardly way.
