Functional Order: Te-Si-Ne-Fi
Hermione strives to bring order where there is none, going so far as to organize extensive charts, study plans, and homework for the boys. The first time they meet her, she is heading up a search for Neville’s toad. Ron finds her “bossy” at first, because she so easily slides into a position of leadership, which later makes her a good Prefect, able to confront and keep students in line, without allowing her personal emotions to influence her actions. Hermione always chooses the most ethical and logical approach, such as turning in Harry’s brand new broom for inspection, because she fears it was sent by an enemy. She is so time-efficient that not only is all her homework finished in advance, McGonagall trusts her with a Time Turner in her third year. She frequently references things she has read about, in explaining how things work at Hogwarts (“I read about it in Hogwarts, A History!”). Hermione comfortably adapts to a schedule and doesn’t mind a routine that involves study sessions and extensive research. She enjoys digesting information and can remember it in enormous quantities, which helps her ace all of her exams. Hermione enjoys participating in the traditions around Hogwarts and doesn’t like Ron and Harry breaking the rules; she trusts them, because they have kept Hogwarts safe and efficient for many years. She trusts the texts in her textbooks to be accurate, and becomes frustrated when Harry follows a new set of instructions, to great success (no, that can’t be right; it’s not what the book says!). Her interest in the unknown prompts her to be a voracious reader, even though she prefers to keep her manufacturing of ideas on topic and on serious matters (discerning motivations of adversaries, coming up with possible solutions to problems, etc). Hermione quickly discerns from her books and observing of Lupin’s behavior that he is a werewolf; her instincts are often right about other students. She is sometimes reluctant to commit to one idea or conclusion about someone else. As a child, when she is disliked, Hermione goes off by herself to cry; she is sensitive and kind but not always aware of how to express her feelings, which leads her into a continual tug of war with Ron in which her feelings for him translate into bossiness. Hermione feels strongly that her friends ought to share the same moral reservations about House Elves that she does, and is annoyed when they show little interest in helping out with S.P.E.W. When making decisions based entirely on those emotions, she can be somewhat irrational (inferior Fi).
Enneagram: 1w2 so/sp 
Hermione is very focused on doing what is right, sometimes without consulting other people or what they want in the process, such as when she decides that having house elves working at Hogwarts is immoral, and insists on leaving items of clothing hidden around the Gryffindor Common Room, so that they will pick up socks, hats, etc., and be “freed” – which is exactly what the elves do not want. They are so offended, they cease to clean the room and leave Dobby to do all the work instead. Other insist to Hermione that what she is doing is stupid and unnecessary, because they don’t want liberation, but she refuses to listen to them and persists in her attempts to recruit people into SPEW. She is studious and hard-working, so reliable and trustworthy that McGonagall trusts her with a time-turner in her third year (a dangerous object most wizards aren’t allowed to possess), so she can take on extra classes. Hermione is quick to answer any question and to correct other students; she lectures Ron on how he’s doing and saying things wrong. She is easily infuriated, and can even be vindictive—she curses everyone who takes part in their secret Defense Against the Dark Arts Class, so that if anyone snitches to them, their face will break out in painful, un-removable blotches so that she knows who did it. She’s afraid of being expelled, more than she’s afraid of dying. She holds herself to impossibly high academic standards and expects everyone else to also adhere to them, and is annoyed when Harry and Ron half-ass their schoolwork. When she decides to do something, she believes wholeheartedly that it is right, and never questioned it even when others fail to get on board. Her 2 wing can be somewhat bossy and intrusive. She genuinely cares about her friends and goes all out to help them, even staying with Harry to help him defeat the Horcruxes when the love of her life leaves in a huff, but she can also be invasive and irritating in her attempts to ‘help’ people who do not want her assistance, and have not asked for her advice. She tells people off all the time, especially Harry and Ron, but also sometimes teachers or authority figures. She also moves to 4 in stress, becoming petty, selfish, argumentative, whiny, and over-reacting—accusing Ron of mistreating her and complaining about being misunderstood, refusing to forgive him or apologize for any of her mistakes.
