Harry Potter: Severus Snape [ISTJ]

Functional Order: Si-Te-Fi-Ne

Perceiving Functional Axis:

Introverted Sensing (Si) / Extroverted Intuition (Ne)

Snape has become an expert at potions, through meticulous repetition, experimentation, and understanding the individual components enough to know how to innovate and create his own potions. He has made this his profession and is highly competent in it, enough to “teach” (not well) others to do it. One of Snape’s biggest flaws is that he was so impacted by James Potter’s actions as a student at Howarts, he assumes history will repeat itself. He persistently blames Harry Potter for things he did not do, he assumes because Harry resembles his father that he will share his callous attitude and bullying behavior, and the mere sight of his son brings back all the old resentment. Once forced to interact with Sirius Black, his primary tormentor, Snape falls right back into the rut of their “previous behavior” – lashing out at him and experiencing all the same subjective emotions (Si/Fi loop). As a young man, he joined with Voldemort and placed his faith in his word, never assuming Voldemort would betray him by killing the woman he loved. His inferior Ne never thought to assume Voldemort capable of betrayal; it takes him decades to realize Dumbledore has protected Harry Potter’s life, so he can “die at the proper moment.” Though a dedicated and effective spy for the Order, Snape’s inability to intuit Voldemort’s intentions eventually causes his death.

Judging Functional Axis:

Extroverted Thinking (Te) / Introverted Feeling (Fi)

Snape is an accomplished Potion’s Master, who scribbled tons of detailed instructions in his old potion’s book. He has gone on to make a successful career out of his knowledge, which is immense… but he does not have good people skills. He can be harsh, judgmental, and abrasive, pointing out people’s incompetence and shaming them. But… he has enough mastery over his own emotions to successfully learn how to block Voldemort from accessing his true feelings. He tries to teach this method to Harry, but becomes frustrated, furious when Harry breaks through into his own mind and sees him abused, and discontinues their lessons. Though he loathes the thought of ending Dumbledore’s life “for the greater good,” Snape rationally realizes it’s the only way to protect Draco from Voldemort’s wrath, earn himself a trusted position in the Death Eater inner circle, and pave the way for his enemy’s eventual downfall. Snape has intense, deep emotions, but often shows them through his actions, his condescension, and his contempt rather than in healthy ways. He behaves childishly around Sirius, and often loops into Fi, engaging in immature overreactions.

Enneagram: 5w4 sexual

Snape is introverted, detached from others, and not interested in heavy engagement with the outside world. His desire to explore the unknown led him as a young man to creating very dark, turbulent spells—such as the one Harry mistakenly uses that slices open Draco Malfoy in a duel. Fives love to create niches for themselves, as Snape did in becoming a Potion Master. He relied on this, as a young Hogwarts student, to set himself apart from the others—this expertise made him “valuable and important.” He thrust aside all other distractions, and focused just on that. His 4 wing and fix made him see himself as intellectually superior to others, as well as utterly incapable of moving past his intense feelings—years later, Snape is still harboring anger, resentment, bitterness, and hurt over being humiliated by James Potter, losing Lily, and having to see Harry Potter’s face in his classroom every day… it’s as if James is still taunting him, from beyond the grave. He acts on these feelings by asserting his authority, and threatening and bullying the children.
