Harry Potter, J. K. Rowling

Introverted Feeling (Fi): Hagrid takes a liking to everyone he meets, unless they give him some reason to be unlikeable.  He is immediately accepting of Ron and Hermione when Harry brings them over for tea, but he can’t stand Draco Malfoy, who is notorious as a bully and a bigot.  His compassion even extends to dangerous monsters (his pets have included dragons, giant man-eating spiders, and vicious three-headed dogs), and he often labors under the delusion that even the most bloodthirsty creatures in existence are, in fact, harmless.  Hagrid has an unshakable loyalty to Albus Dumbledore, and will physically attack anyone who dares to insult him, but that doesn’t stop him from criticizing Dumbledore to his face when he believes the Hogwarts headmaster is making a mistake.  Hagrid is very emotional, but he doesn’t like to show his feelings to anyone else; when he is found to be a descendant of giants, he retreats to his cabin for several weeks, brooding on his shame and embarrassment alone.  Hagrid takes it personally when Harry, Ron, and Hermione discontinue taking Care of Magical Creatures in their sixth year, and the three of them have to convince him that they are not actually snubbing him.

Extroverted Sensing (Se): Hagrid spends many years working as the Hogwarts gamekeeper, a physically demanding job that he enjoys.  He is eventually appointed to teach Care of Magical Creatures, and he strongly prefers hands-on lessons; he barely uses books at all when he teaches.  Hagrid can fight hard when he has to; he single-handedly bests five people when they try to forcibly remove him from Hogwarts, and he holds off a horde of giant spiders while rescuing the body of their deceased leader.  Hagrid often speaks and acts on impulse; he buys an illegal dragon egg off a stranger, and on multiple occasions, he spills the beans on how to bypass his protection for the Sorcerer’s Stone.

Introverted Intuition (Ni): Hagrid can correctly infer things that he doesn’t really know.  Even when most of the wizarding world believes Voldemort to be dead or “biding his time,” Hagrid holds that neither of these theories is true.  He also guesses that Gilderoy Lockhart is a giant fraud, and that he can’t have possibly done all the things that he has documented in his books (also a correct guess).  Hagrid needs an outside influence to prepare for an important event; Harry, Ron, and especially Hermione have to help him do his research when his hippogriff, Buckbeak, is on trial.

Extroverted Thinking (Te): Organization is one of Hagrid’s weak points.  He can barely keep order when he is teaching; he pays no heed to students who talk while he is speaking, and he sometimes allows Draco Malfoy and his friends to hijack his classes.  However, even though Hagrid doesn’t necessarily keep his students organized, he can keep himself organized.  His classes are clearly planned out, he is careful to have all the facts about what he is conveying, and the students who actually pay attention to him learn a great deal.  Additionally, he seems to be under no stress for having two jobs at once.

Note: Hagrid is also typed as ISFJ.  This is wrong because Hagrid seems unaware of many social norms, and he has a tendency to break rules and even laws under the table.
