Functional Order: Fi-Se-Ni-Fe

 Judging Functional Axis:

Introverted Feeling (Fi) / Extroverted Thinking (Te)

Jonathan tells his brother, “You shouldn’t have to like, or pretend to like, something if you do not really like it.” That’s how he operates in his reality, through his strong opinions and feelings of like / repulsion. He doesn’t think Nancy should put up with Steve’s disloyal behavior, and stands up for her when the others call her a slut. Jonathan has a quiet emotional intensity that pervades many of his decisions, from his silent adoration for Nancy, which manifests in taking pictures of her and punching out anyone who insults him, to his emotional support of his mom. Once his brother goes missing, Jonathan internalizes all his feelings, and never shares his fears. He sinks into his photography and ideas about what happened, in order to deal with his emotions. His inferior Te shows in his ‘take charge’ attitude under stress (as he and Nancy set up a bunch of traps for the Demigorgon) and the fact that he doesn’t care where the creature came from or what it wants; he just wants to kill it and protect his family!

Perceiving Functional Axis:

Extroverted Sensing (Se) / Introverted Intuition (Ni)

He sees the world through the lens of his camera, but has no illusions about anyone in his life; his dad is a jackass who left them; his mom is over-worked and hysterical; his brother is a sweet little guy who needs to find his way in the world; Nancy is something special (though she doesn’t know it yet), and Steve doesn’t deserve her. His mother’s intuitive theory about Will sounds nuts to him, until he finds actual physical proof of the monster, which he then translates into immediate action. He’s not above risk-taking, and has a singular focus once he commits to a task. He and Nancy work together to form singular conclusions about what’s going on and come up with a plan of action, which includes trapping the creature in his home.

Enneagram: 4w5 self-preservation

Jonathan’s conversation with his brother about his taste in music, and how he allows others to influence his likes and dislikes, perfectly sums up his 4: what’s wrong with being different from other people and liking things they do not like? He is the embodiment of a loner who dwells deeply in his feelings, but also has a strong intellectual and reserved side (5), which shows in how calmly he handles his brother’s death and the funeral arrangements – even while his 6 mother is “freaking out.” He does not actively pursue Nancy, out of fear of rejection, so instead he pines for her.
