Functional Order: Fe/Si/Ne/Ti
Dominant Function: Fe
Cora reflects back the emotions of those around her, such as taking on O’Brien’s feelings toward Mr. Bates and passing them on to her husband. She prioritizes her family and friends, but also has a deeper sense of appropriateness that extends to those in the household and how they come across in society. She is quick to smooth things over, but also to assert how she feels forcefully – making it known what she will and will not stand for, as regards her house, and putting others in their place when it comes to them criticizing her children.
Auxiliary Function: Si
Like Robert, she enjoys having things predictable at home. She’s relieved to turn her house back into a country estate after the war and send the soldiers off home—there’s no need to make permanent changes, after all. Cora enjoys being in the middle of things and volunteering for committees, but also likes to be at home with her family. She tends to focus on the everyday necessities of life—such as finding appropriate suitors for her daughters, though she does readily latch on to new ideas and considers progress a necessary evil.
Tertiary Function: Ne
She has broad, contextual thinking in terms of cleaning up Mary’s scandals (how it could impact all of them and her future prospects) and she’s more able to access the “bigger picture” than Robert (“She should get married soon, Robert…”).
Inferior Function: Ti
She often relies so much on appearances, and how things look to others (is it bad to have a crippled servant?) that she doesn’t stop to reflect, to analyze the situation, or consider what is the driving force behind others’ actions (inferior Ti).
