MBTI®, Hogwarts House sorting quizzes, zodiac signs, "tag yourself" and "what's my vibe" memes: there are many fun and insightful ways for people to categorize their personalities, and the Enneagram is just one more fun way to do this. The Enneagram Model of Personality determines which of the nine categories (and three subcategories: body, instinct; head, analysis; heart, emotions) people fit in to, based on their actions, behaviors, beliefs, personalities, motivations, fears/desires, and more.

The enneagram can be applicable to characters in television, movies, books, comics, video games, and other art mediums people connect to and provides a way for fans to relate to their favorite heroes and love-to-hate, hate-to-love villains, much like in Apple TV's bio-dramedy Dickinson.

Enneagram Type 1: Mrs. Dickinson

Known as "The Perfectionist," Type 1's play by the rules, uphold tradition and doing things right, and have high standards. They are responsible, exacting, and fairly high-strung. Additionally, they are detail-oriented, hard-working, and have intense focus and concentration when completing a task. Their biggest fear is being seen as a "bad person" and anything less than perfect, which leads to the tightly bound, disciplined nature they have.

Mrs. Dickinson, in her respect for societal and cultural institutions, her deliberate and hard work as a wife and mother, and attention to detail (in particular during the tea parties in season 2) makes her a perfect Type 1.

Enneagram Type 2: George Gould

"The Giver," these folks are eager to be loved, adored, and needed by those around them. They insert themselves into people's lives as a strength and show of support, as well as being nurturing and caring for the people they surround themselves with, placing their value in how they can be there for others, and they fear being unloved and unwanted. They have a warm smile and eyes, are approachable, allies to people they care about, and are patient people.

George Gould is a Type 2 through and through, as he supports and encourages Emily's poetry career despite 19th-century America's rigid gender roles, tries to watch out for her when she seeks the help of Henry David Thoreau, and continues to be her friend after she scorns his romantic advances.

Enneagram Type 3: Samuel Bowles

Also known as "The Achiever," no character from Dickinson is more apt for this personality type. Threes concern themselves with being successful, distinguished, and admired. They obsess over their public image and to achieve. They are confident, career-and-goal-driven, and ambitious. They seek validation and self-worth through hard work and accomplishments. Furthermore, they are concerned with social niceties, remain busy, are charismatic, and a refined taste for the finer things in life, and have a fear of failure and of being seen as worthless.

Sam Bowles, editor-in-chief of the Amherst (MA) newspaper, is the poster boy for this type: he will do what he must in order to be the leading newspaper in the MA and in the country, is progressive for the time in his publication of women, and enjoys his share of parties and public gatherings where he can show off.

Enneagram Type 4: Emily Dickinson

This model personality is "The Individualist" and, as such, are defined by their sense of uniqueness, difference, and being special from other people. They are the creative type and try to set themselves apart in many ways from society, culture, institution, and tradition. Fours are hyper-aware of their individuality and unusualness and long for deep emotional connection, but afraid they will miss out because of it. They compensate by amplifying what makes them peculiar in hopes that they will find their niche.

Quirky and endearing, passionate, and with a strong sense of self, Emily Dickinson, played brilliantly by Hailee Steinfeld, encompasses all of these with her intelligence and wit, in her relationship with Sue, and in her resistance to 19th-century American norms and mores.

Enneagram Type 5: Mr. Dickinson

"The Investigator" of the enneagram types, these people love learning, soaking up knowledge, and being a competent and self-sufficient as possible. Fives long to broaden their understanding of the world and expand their scholarly pursuits, while keeping their emotional and spiritual nourishment minimized. They are insightful, slow to speak, and have clear lines between family, friends, and work. They are afraid of the emotional demands others may have of them, so they withdraw from those and seek solitude to study instead.

Mr. Dickinson is, unquestionably, a 5: he is always working on something and attempting to learn more new subjects and interests, avoids talking to his wife about pressing personal home matters, and doesn't appear close to his children.

Enneagram Type 6: Sue Gilbert-Dickinson

"The Skeptics" of the enneagram personality model are concerned with their safety, security, and like to be one or two steps ahead of any potential problems. They are on the alert and vigilant in getting what they seek in order to feel secure and comfortable. Organized and well-liked, as well as precise and good managers, 6's fear being unprepared and vulnerable to danger.

After the death of her family, Sue becomes hyper-vigilant about securing housing, a home, and an income in marrying Austin. She also hosts salon parties and tries to get her soirees in the local Amherst newspaper in order to draw love and support from the public.

Enneagram Type 7: Lavinia Dickinson

Type 7's, "The Enthusiasts," seek life experience, hedonistic pleasure, and love adventure. They despise boredom and remaining static, still, and one-dimensional. They are also fun-loving, lively, and bounce from one enjoyable activity to the next. Additionally, 7's have a ton of energy, vitality, and adrenaline. They are optimistic, upbeat, and well-liked, with a curious, childlike sparkle in their eyes and smile, and they avoid sadness at all costs, as being depressed is a significant fear.

Lavinia, the other Dickinson sister, is all these things: she aspires to be like the seductive, adventurous, bold, and daring Lola Montez, sketches herself nude, and also detests being bogged down by marriage and family constructs.

Enneagram Type 8: Henry

"The Challengers" of the enneagram types, these people are powerful in many ways and seek to challenge the status quo. They are confident, assertive, and stand up for their convictions, as well as to speak for those who cannot speak for themselves. Furthermore, 8's have determination, stamina, and are headstrong and stubborn. They have fire in their souls and are unafraid to be independent and self-sufficient in the face of trials, but fear losing control of their environment.

No other character on Dickinson portrays this better than Henry, as viewers see him create the press in Austin's barn, speak power to the truth of the immoral, hypocritical institution of slavery, and confront Emily on certain issues, taking her to task with her own set of privileges. When henry has to flee after the trigger of the Civil War, the audience sees one of his greatest fears come to life, and he runs to safety with his family in tow.

Enneagram Type 9: Austin Dickinson

The last of the enneagram types, "The Peacemakers" have a go-with-the-flow attitude and like to avoid confrontation and inner-emotional turmoil. Generally, they are calm, agreeable, and docile, easy to be around and get along with. Moreover, they aim to be cool and collected, as well as mellow and zen. They are well-liked among their peers and have a large circle of friends and acquaintances. They fear being pushed away by being too needy, so they agree with others in order to feel included.

The Dickinson brother is a clear 9, as he throws a tea party for his college friends, avoids fighting with his wife Sue, and likes to take in all the parties he throws in Amherst for the popular, young crowd.
