Harry Potter, J.K. Rowling
Dominant Te: Umbridge loves to be in charge and likes to take over and manage pretty much every part of the system. She wants to organise everyone and obsesses over instituting and upholding rules. She feels the need to control so much that she employs spies and punishes anyone for breaking the rules. She doesn’t care about other people’s feelings so much as she does about order and as a result ends up employing some very cruel methods for enforcing law
Auxiliary Si: Umbridge is obsessive about previously established methods and likes to butt her head in wherever a teacher is employing unconventional or out-of-the-box teaching methods. Any teacher who is different gets fired. Her network of spies act as an information collector for Umbridge and she is an advocate for the idea of “knowledge is power.” Tradition is so important to Umbridge that she tries to implement new ones.
