Introverted Sensing (Si): Mace believes that keeping to established precedents is the best thing for the Jedi Order. In his mind, nobody is exempt from the rules for who may and who may not be trained as a Jedi, not even Anakin Skywalker, allegedly the “Chosen One” who is destined to bring balance to the Force. Mace needs to have all the information before he reaches any conclusion, from the alleged return of the Sith to the identity of the mysterious Darth Sidious, and he devotes a great deal of time, energy, and resources toward gathering information. Mace is most comfortable working within the system of the Jedi Order and the Republic, and he is thus blinded to the eventual use of this system to destroy the Jedi.
Extroverted Thinking (Te): Mace prefers acting with others to acting alone, and he generally feels a need to take charge when something needs to be done. He can organize people toward specific goals, but is often oblivious to how anyone will react emotionally to his decisions, as the only matters that he takes into account when assigning duties are competence and usefulness. Mace looks for empirical evidence to inform his decisions; he runs a series of tests on Anakin to gauge his aptitude for using the Force, and he encourages a confrontation between Qui-Gon and Darth Maul to ascertain whether Darth Maul is, in fact, a Sith Lord. Mace keeps his communication direct, making his point of view clear from the get-go.
Introverted Feeling (Fi): When push comes to shove, Mace will sometimes abandon the niceties of the Jedi Code and try doing things his own way. He is ready and willing to kill Palpatine after the latter is disarmed and apparently helpless. Mace generally represses his emotions, and doesn’t factor them into his decision-making process. Additionally, he doesn’t consider that others are more driven by their feelings than he is by his own; he even shuts down Obi-Wan when he brings up Anakin’s love for Padme as a stumbling block for his mission as a Jedi.
Extroverted Intuition (Ne): Mace has devised a new style for fighting with a lightsaber; it is all his own and based mainly on unpredictability. He can have trouble viewing the big picture (his view of the Sith menace is hazy at best), and when he gets a glimpse behind the scenes, he will take actions that are ill-judged and impulsive (he moves against Palpatine immediately upon hearing that the Supreme Chancellor is Darth Sidious).
