Harry Potter, J. K. Rowling

Introverted Thinking (Ti): Mr. Ollivander doesn’t mainly produce and sell wands for profit; he does it for the pleasure of doing it, because he likes the mental exercise. He doesn’t want to make a quick sale by rushing Harry out of his shop with just any wand, and he even seems to enjoy the process of picking the best wand for Harry. Mr. Ollivander tends to say things that are irrelevant to the task at hand, and his specially enchanted tape measure will measure his customers in irrelevant ways. Mr. Ollivander has a morbid curiosity about what would happen if Voldemort becomes the master of the Elder Wand, regardless of the implications.

Extroverted Intuition (Ne): To many, Mr. Ollivander seems otherworldly, or else detached from reality. Although he is a businessman with a living to make, he behaves more like an ivory-tower academic than anything else. Mr. Ollivander can guess exactly which wand will be suitable for each of his customers, and he is the first one to say that the proper wand for Harry his the brother to Voldemort’s wand. As Mr. Ollivander himself says, no two of his wands are exactly the same.

Introverted Sensing (Si): Mr. Ollivander proudly displays on his door that his shop has been in business for over two millennia. He remembers every customer he has ever had, and exactly what wand each of them purchased. When Voldemort’s agents show up at his door, Mr. Ollivander goes with them quietly (there is no evidence that he tries to fight them off). He is considered to be the expert on everything related to wandlore, so much that others (e.g. Voldemort) accuse him of lying if his predictions don’t come true.

Extroverted Feeling (Fe): Mr. Ollivander is generally detached from emotions, whether his own or anyone else’s. He just isn’t into being a nice, warm, sociable guy. Even so, he knows right from wrong, he wants good things to happen for everybody, and he expresses gratitude to Harry for rescuing him. Mr. Ollivander refrains from using magical substances in his wands (such as veela hairs) that will make them “temperamental.”
