Extroverted Thinking (Te): Professor McGonagall is a strict teacher who has high standards, both in work and in general discipline, for her students. She sets plenty of rules and boundaries, and doesn’t fail to punish students who step out of line. As Deputy Headmistress of Hogwarts, it is Professor McGonagall, rather than Professor Dumbledore, who sends out admission letters and book lists, possibly because she is a great deal more organized than her boss is. In Dumbledore’s absence and after his death, Professor McGonagall comfortably steps in to lead the school (briefly in each case), and she assumes command of the defense of Hogwarts when Lord Voldemort is about to invade the school. Professor McGonagall is blunt and outspoken; she always speaks her mind in a forceful manner, usually without caring whose toes she steps on.
Introverted Sensing (Si): Professor McGonagall always likes to ensure that the rules and traditions of Hogwarts are respected. She insists that Harry find a date for the Yule Ball (because the school champions always open the dancing). Professor McGonagall has a great respect for Albus Dumbledore, so much so that she takes his words at face value and measures anything that anyone else has to say against them. When acting in Dumbledore’s stead, she follows his instructions to the letter. To Professor McGonagall, the past is the best indicator of what the future will hold; since Professor Trelawney always predicts the death of a student in every year and none of them actually die, there is no reason to believe that Harry should be an exception to the trend. When faced with situation with no precedent (a teacher killing a headmaster at Hogwarts, for instance), Professor McGonagall can be unsure of the best course of action.
Extroverted Intuition (Ne): Professor McGonagall is the first person to identify Harry’s potential as a Quidditch player; she sees him flying on a broomstick and appoints him to the Gryffindor team right away. For any students who are unsure of what classes to take after their fifth years, she can help them find the best choices. Professor McGonagall can sometimes guess what her students are up to when she sees them in unusual situations, especially if it is consistent with something she remembers from before (Si-Ne). She can anticipate and prevent any conceivable method that students could use to cheat on their exams.
Introverted Feeling (Fi): Professor McGonagall is always certain of what is right and what is wrong morally. Even though she can give out harsh punishments to rule-breakers, she is fair in her discipline; she only hands out punishments when legitimate rules are broken, and she doesn’t play favorites. Professor McGonagall does not make emotional decisions, but she does care deeply about some people (e.g. Harry and Dumbledore). In addition, she is very protective of the students at Hogwarts, and she will go so far as to subvert her superiors if they pose a danger to the students’ welfare.
