Chapter 5. The Mirror of Self-Objectification: The Stage Where Measures Abstract a Person

In the last chapter, we decided on one-line seeds. M's seed: “A forensic pathologist with thirty years of experience. On finding her mother's lost ring on a corpse, she confronts the strength she has deliberately kept hidden.” J's seed: “A writer who wants to become a bestseller while struggling not to lose the pleasure of writing itself.” We have the two seeds in hand.

A one-line seed does not yet make a person live and move. A line is only a starting point. The second stage is to hold a mirror to the person standing at that starting point and abstract, once, what kind of person they are. Five kinds of measures serve as that mirror. When the five measures are complete, the person's one-word identity emerges.

Today we cover the five measures, supplementary measures, and the work of extracting a one-word identity from their results.

A Mirror Is Not Self-Projection

First, let us establish the posture for the mirror stage.

Mary Sue: a term for an avatar-like character onto whom an author directly projects their wishes—a flawless double loved by everyone. The expression arose in fan-fiction culture, and it names exactly the trap the mirror stage guards against. Remember only that the mirror is a tool for reflecting the character, not the author, and the trap is easy to avoid.

This stage is not work that projects the character onto the author themself. If an author simply puts their own personality on a character, every character becomes the author's double. That is not the result we want.

The mirror is a tool for self-objectification. After an author has looked at themself once through MBTI, Hogwarts, and seven black-and-white axes, they apply that same objective posture to the character. This lecture addresses only the mirror held up to the character, on the assumption that everyone has already passed through their own mirror once. Applying a measure one has never tried without warning produces awkward results.

Origins of the Mirror Metaphor

The metaphor of objectively seeing oneself in a mirror has a long history in psychology, sociology, and coaching. Lacan's 1949 mirror stage is a psychoanalytic developmental theory in which a child constructs an ego through their image in a mirror. Cooley's 1902 “looking-glass self” is a sociological concept in which others' responses form one's self-image. In coaching and counseling, a mirroring technique is a method in which a coach or therapist reflects a client's words back so that the client can see themself. In creative theory, a foil is a contrasting character who makes a protagonist's traits stand out as though in a mirror.

This work borrows that mirror metaphor but narrows it for a character-creation workflow in two ways. First, it uses a double-application structure: apply measures once to the author and then once to the character. Second, rather than open-ended self-exploration, it makes a predetermined result—a one-word identity—its destination. These two points redesign the general mirror concept as a character-building tool.

A foil makes the protagonist stand out as though in a mirror by placing an opposite texture beside them. In Don Quixote, the feet-on-the-ground Sancho Panza makes the ideal-intoxicated Don Quixote clearer; in The Great Gatsby, the calm observer Nick Carraway reflects both Gatsby's splendor and emptiness. Because establishing one person well also sharpens the person beside them, a foil is the most economical mirror.

Five Kinds of Measures

There are five kinds of measures used in the mirror. MBTI primary and secondary functions capture disposition (what a person is comfortable with and what they struggle with); the four Hogwarts houses capture values (what they consider most important); the seven black-and-white axes capture everyday tendencies (which direction they lean in each area); the thirty core rapid questions capture the stream of consciousness (thirty answers given within five seconds); and supplementary measures add depth (through the Big Five, the Enneagram, personality quadrants, developmental stages, and so on). When all five are complete, the person's five faces gather in one place, and compressing them into one word is the final work of this stage.

Let us examine the five measures one at a time.

MBTI Primary and Secondary Functions

Background

MBTI[^c5n1] is a personality-classification tool based on Carl Jung's theory of psychological types and organized by the Briggs mother-and-daughter team into a sixteen-type model in the mid-twentieth century. It compresses a person's disposition into a four-letter code.

The four Hobbit friends in J. R. R. Tolkien's The Lord of the Rings belong to the same people, yet their textures are clearly distinct. Frodo has thoughtful responsibility, Sam steadfast loyalty, Merry quick practical sense, and Pippin innocent curiosity. Even when the same measure is applied, the four land in different places. A personality measure is not a tool for imprisoning a person in one cell; it is a tool for designing their differences from the people placed beside them.

The four letters mean the following. In the first position, E (Extraversion) / I (Introversion) indicates the direction of energy (recharged externally vs. internally). In the second, S (Sensing) / N (iNtuition) indicates information processing (concrete and present vs. abstract and future). In the third, T (Thinking) / F (Feeling) indicates the criterion of judgment (logic and fairness vs. values and harmony). In the fourth, J (Judging) / P (Perceiving) indicates one's relation to the external world (planning and deciding vs. flexibility and adaptation).

The combinations of four letters yield sixteen types: four-letter codes such as INFJ, ESTP, and ISFJ. Each type has behavioral and decision-making patterns that often accompany it.

Rationale for Adoption

MBTI is a tool whose reliability and validity are debated in academic psychology. For research, other five-factor models such as the Big Five have stronger validation. Even so, there are two reasons this work adopts MBTI as its first mirror.

First, public familiarity. MBTI is among the most frequently used tools for character settings in novels, films, and games in both Korea and the United States. When an author is shaping a character, an expression such as “an ENTJ-style ambitious person” is immediately understood. A tool with vocabulary that can be shared with the public is useful for character building.

Second, its capacity for compression into a one-word identity. Its structure makes it easy to choose two of the four letters and compress them into one word, which fits the compression posture of the first stage of this procedure.

The Simplified Model Used in This Work

One caution must be made in advance. There is a widely used interpretive framework of cognitive functions for MBTI. For example, it reads an INFJ's dominant function as Ni (introverted intuition) and auxiliary function as Fe (extraverted feeling). The “primary and secondary functions” used in this work differ from that framework. Here, “primary and secondary functions” are a creative simplification model for choosing two of the four letters and extracting a one-word identity.

The method for this simplified model is as follows. Choose one letter from each of the middle two positions (S/N and T/F), then compress the person's texture into one word. For INFJ, N (intuition) + F (feeling) becomes “idealist.” For ISTP, S (sensing) + T (thinking) becomes “realist” or “technician.”

Expected Effect

Once a character passes through the MBTI simplified model, their texture is compressed into one word. That word becomes the name by which the person is called throughout the following eleven stages. The proper role of this tool is not precise academic classification, but establishing a texture that remains consistent within the work.

If you want to refer to the cognitive-function framework as well, we recommend pairing it with supplementary measures such as the Big Five, where validation research has accumulated. The fifth measure in this procedure is supplementary measures, where depth can be reinforced.

The procedure is simple.

Decide the character's four-letter MBTI code.
From the middle two letters (S/N and T/F), select one each (or any two letters) as the primary and secondary functions.
Extract a one-word identity from the combination of the two letters.

The producer decides the four MBTI letters directly. They may receive candidates together with an AI work partner, but judging which type suits a one-line seed belongs to the producer.

Extracting the one-word identity in the third step is also the producer's direct work. The producer may receive five one-word candidates together with an AI work partner, but deciding which candidate most accurately captures the character's texture belongs to the producer. Because that word recurs frequently in later stages, no one else can decide it in their place.

Examples: M and J's MBTI

Let us apply it to the two people.

M (the forensic pathologist)'s full code is ISFJ. The primary function F (feeling) keeps others' emotional states in mind without putting them on the surface; the secondary function S (sensing) is strong at concrete, repetitive work but weak at abstraction. The one-word identity is “quiet witness.” Secondary effects include avoiding unnecessary confrontation, sensitivity to small changes in colleagues, and stinginess about showing their own feelings.

J (the writer)'s full code is INFJ. The primary function F (feeling) empathizes deeply with others' emotional states; the secondary function N (intuition) is strong in abstraction and insight. The one-word identity is “idealist.” Secondary effects include a strict moral sense, despair at social injustice, and stubbornness.

Both people have F as the primary function, but their secondary functions differ: M has S, J has N. Even the same F produces different people when supported by S or by N. M operates feeling in the realm of the concrete and repetitive, while J operates feeling in the realm of abstraction and insight.

This difference works throughout the later stages. It is why M's everyday-slice scenario and J's everyday-slice scenario have different tones, why M's conflict arises from concrete events and J's conflict arises inside self-consciousness. It all begins with these two letters.

The Four Hogwarts Houses

Background

The four Hogwarts houses are the houses of a wizarding school in J. K. Rowling's Harry Potter series. They classify students as Gryffindor (courage), Ravenclaw (wisdom), Hufflepuff (devotion), or Slytherin (ambition). What this work borrows is not the classification itself, but the four patterns of values represented by the houses.

Even at the same school and at the same age, priorities differ when houses differ. Hermione in Harry Potter is a Gryffindor who loves knowledge and rules but chooses courage in decisive moments; Draco Malfoy is a Slytherin who puts bloodline and ambition first. Cedric Diggory's fairness has the texture of Hufflepuff, and Luna Lovegood's eccentric insight the texture of Ravenclaw. Put the four in the same crisis and each will speak a different first line.

Rationale for Adoption

Where MBTI captures disposition (what a person is comfortable with), Hogwarts captures values (what a person considers most important). The two areas differ. Even with the same disposition, action diverges when values differ.

There are two reasons this work adopts Hogwarts. First, it is a classification of values that arose naturally from a story, not an academic tool. Narrative vocabulary enters more naturally for an author building a character's texture than an academic classification table. Second, the four values can be identified by a memorable line under threat. The difference between Gryffindor's “I'll die for you” and Slytherin's “I'll kill for you” can be seen in one line. It suits this procedure's posture of grasping a character's texture in one line.

Expected Effect

After passing through the four Hogwarts houses, a character's values are established. When the values captured by Hogwarts are layered onto the disposition captured by MBTI, it becomes clearer where and how the same person will decide.

The same disposition produces different people when values differ.

To summarize the four houses: Gryffindor (selection criteria: courage and daring) holds the value of chivalry and says under threat, “I'll die for you.” Ravenclaw (wisdom and creativity) holds the scholar's value and says, “I'll find a way for no one to die.” Hufflepuff (devotion and tolerance) holds the value of cooperation and says, “I'll die with you.” Slytherin (ambition and power) holds aristocratic pride and says, “I'll kill for you.” These lines identify them.

The procedure is to put four questions to the character and answer in the first person.

To which house is this person sorted, and why?
What value do they want to learn in that house, and what class or activity do they challenge themself with?
Which house attracts them? (Erotic attraction and a role model can differ.)
Which house is furthest from them, and how do they react if they are sorted there by mistake?

Receive first-pass answers to these four questions together with an AI work partner. If you provide a one-line seed and the MBTI result as input, the AI can quickly draft four answers. The producer checks whether the answers match the character's texture.

M's Hogwarts house: Hufflepuff. Devotion, tolerance, cooperation. Their posture of working in the same forensic pathology department for thirty years, of being with coworkers for thirty years without knowing their first names, and of wanting to remain beside the dead: all have Hufflepuff's texture.

J's Hogwarts house: Ravenclaw. Wisdom, creativity, the scholar's spirit. Their posture of finding meaning in the act of writing itself, of placing process before results, has Ravenclaw's texture.

When the Hogwarts result combines with MBTI, the person's texture becomes clearer. M is an “ISFJ + Hufflepuff” person, and J an “INFJ + Ravenclaw” person. Two lines alone give the broad picture of how the two will live.

Seven Black-and-White Axes

Background and Rationale for Adoption

The seven black-and-white axes are measures for capturing everyday tendencies. Where MBTI captures disposition and Hogwarts captures values, the seven black-and-white axes capture the texture of everyday behavior. Even with the same disposition and values, people may lean in different directions in daily life.

This measure is not an academic classification but seven creative axes organized for this work. It is simpler than other academic tools (such as the Big Five), but useful for rapidly establishing a character's everyday texture.

Expected Effect

If one side is selected decisively on all seven axes, the shape of the character's daily life can be seen at a glance. If all seven axes lean only to one side, or all to the other, the character is flat. A distribution in which some axes lean strongly one way and others weakly the other creates a dimensional texture.

Organize the direction in which a person leans in each domain through seven axes.

1. leading vs. led
2. timid vs. bold
3. sensitive vs. insensitive
4. sociable vs. isolated
5. realistic vs. idealistic
6. warm vs. prickly
7. calm vs. scattered

Mark which of five positions the person occupies on each axis. At the start, make a forced choice of one side and do not choose the middle position among the five. Dimensionality belongs to later stages; at this stage, make the person flat on purpose.

The procedure is simple: make a forced choice on each of the seven axes. If you give a one-line seed and the MBTI and Hogwarts results to an AI work partner, you can receive recommendations for all seven axes. The producer reviews and adopts those recommendations.

M's seven black-and-white axes (summary): led / timid / sensitive / isolated / realistic / warm / calm. However, separately establish a tension between outward warmth and inner prickliness. J's seven black-and-white axes (summary): led / timid / sensitive / isolated / idealistic / warm / calm.

The two people lean to the same side on five of the seven axes. The key difference is the realistic–idealistic axis, reinforced by the tension M alone has between outward warmth and inner prickliness. M works within reality while concealing their less gentle self; J works gently in the realm of ideals.

Optional Additional Seven Axes

Beyond the basic seven axes, there are seven axes to switch on depending on the nature of the work. When seven axes do not seem to capture all of a person's daily life, use one or two of the following seven in addition.

1. active vs. passive
2. trust vs. suspicion
3. short-term orientation vs. long-term orientation
4. emotional display vs. emotional concealment
5. loss avoidance vs. loss acceptance
6. group vs. individual
7. tradition vs. reform

These seven axes take on different importance by genre. In political drama, axes 4, 5, and 7 work strongly; in family drama, axes 1 and 6 are central; in mystery, forcing a choice on axis 2 determines the work's tone. You need not turn on every axis. Add only one or two that suit the work.

Thirty Core Rapid Questions

The fourth measure is to answer thirty short questions within five seconds. What the stream of consciousness captures is the core of this work.

The questions are as follows.

01. First thing in the morning
02. Just before sleep
03. Greatest fear
04. A keepsake
05. A habit to change
06. If you win the lottery
07. A superpower you want
08. If you were born again
09. A song you often hear
10. Last time you cried and why
11. One meal before death
12. Phone wallpaper
13. What you dislike most in the mirror
14. A secret not told to family
15. Fewer than five friends?
16. Belief in God
17. Fear of death
18. First love: first meeting
19. The lie you regret most
20. What kind of person you are when drunk
21. A place you often go
22. A word you like
23. A word you dislike
24. Use of social media
25. First reaction when dismissed
26. First reaction on seeing someone cry
27. Yourself in one line five years from now
28. Having children
29. The last lie
30. Yourself answering now

Answer these thirty while inhabiting the character. Each answer is one line, given within five seconds. Do not censor it; use the first answer that comes to mind.

This is the part of the stage where AI use is especially strong. If you provide the seed, MBTI, Hogwarts, and black-and-white results as input, an AI can quickly draft thirty first-pass answers. The producer reviews the answers received and revises any that do not suit the character's tone. The time taken to write directly varies with the person and production method, but combining an AI draft with review substantially reduces repetitive work.

Answering questions while inhabiting a person is a staple of acting training. Many actors conduct a “character interview” while preparing for a role. They answer questions such as “What are you most afraid of?” spontaneously as the character, filling within themselves the blanks that the script leaves open. The thirty rapid questions use the same device: they aim to let the character's body respond before the head designs.

Some of M's thirty answers (after review):

03. Greatest fear: Losing my mother's wedding ring again.
05. A habit to change: Stopping at the self-checkout in the supermarket.
14. A secret not told to family: The suspicion that I may know where my mother is.
17. Fear of death: I am not afraid. I handle it every day.
22. A word I like: Accuracy.
27. Myself in one line five years from now: In front of the same autopsy table.

Only six answers are shown, but in these six M's texture gathers in one place: a person who likes accuracy, does not fear death, expects to be before the same autopsy table five years from now, and carries a secret about their mother.

Supplementary Measures

After the five measures are finished, a one-word identity can be extracted. Add supplementary measures only when the work needs more depth. Five measures are enough for a short work; for a novel or series, add one or two; for a villain, antihero, or morally gray character, call on other measures such as the Dark Triad and HEXACO at Stage 7.

Dark Triad: a psychological concept that groups three darker tendencies: Machiavellianism, which uses others as means; narcissism, which over-elevates the self; and psychopathy, in which guilt is faint. It is often borrowed when establishing the texture of a villain or antihero. It is safer, however, to use it not as a diagnostic name but as vocabulary for a person's shadow. (HEXACO is a six-factor personality model that adds a “honesty–humility” axis.)

There are four commonly used supplementary measures. Big Five (OCEAN)[^c5n2] is a five-factor model with a substantial body of research. It fills gaps in MBTI simplification by scoring openness, conscientiousness, extraversion, agreeableness, and neuroticism from 0 to 10. One or two extremes in the score distribution become points of appeal, and the neuroticism and agreeableness dimensions provide reference points for determining the four axes of flaws at Stage 7. The Enneagram's nine types[^c5n3] are used not as a validated diagnostic tool, but as a supplementary creative frame for exploring pairs of core desire and core fear. Summarizing a character's primary type and their change under stress in two lines becomes a starting point for designing Stage 7 flaws and trauma. DISC's four quadrants[^c5n4] simply distinguish behavioral tendencies as D (dominance), I (influence), S (steadiness), and C (conscientiousness), and are useful where rapid recognition matters, such as business or game-NPC design. Persona and shadow are two concepts borrowed from Jungian psychology; examine the distance between a social mask and an aspect difficult to accept in order to anticipate latent conflict. The greater the distance, the more room there is to design the person's conflict deeply.

All four supplementary measures are areas where AI use is strong, and the producer reviews the first-pass assessment.

Developmental Stages: Inner Crises by Age

Where the other measures capture texture in dimensions outside time, Erikson's eight stages[^c5n5] capture the temporal axis. Even people with the same texture have different inner crises depending on whether they are twenty-five or fifty-five. Stage 1 (ages 0–1): trust vs. mistrust; Stage 2 (ages 1–3): autonomy vs. shame; Stage 3 (ages 3–6): initiative vs. guilt; Stage 4 (ages 6–12): industry vs. inferiority; Stage 5 (ages 12–18): identity vs. role confusion; Stage 6 (ages 19–40): intimacy vs. isolation; Stage 7 (ages 40–65): generativity vs. stagnation; Stage 8 (ages 65+): ego integrity vs. despair. For an adolescent protagonist, the crisis of Stage 5 connects directly to later conflict design; for a middle-aged protagonist, the crisis of Stage 7 does.

M (55) is in Stage 7 (generativity vs. stagnation). It is a time to examine whether their work as a forensic pathologist of thirty years will continue into the next generation. When the discovery of their mother's wedding ring combines with this crisis, M begins again to ask what the thirty years of work were directed toward. J (mid-thirties) is between Stages 6 and 7. The remainder of intimacy vs. isolation and the beginning of generativity vs. stagnation operate at once; while examining the meaning of their own writing, J rearranges their relationships with people.

One-Word Identity

Once the five measures and supplementary measures are complete, finally extract a one-word identity. This word becomes the name by which the person is called throughout the following eleven stages.

The extraction procedure is simple. Gather the results of the five measures in one place, then generate about five to ten candidates that can compress those results into one word. Generating candidates is an area for AI use. Judging which word best captures the person's texture and adopting it is the producer's direct work.

M's one-word identity: “quiet witness.” A person who has recorded the final moments of the dead for thirty years. Silent, but seeing everything.

J's one-word identity: “idealist.” A person who places the value of the act above the value of its result. A person who finds meaning in the act of writing itself.

The two words do not contain everything about the two people. They may not contain even half. They are made that way deliberately. When the next stage, the everyday-slice scenario, puts prose clothing over these words, the half the words cannot hold finally appears in prose.

A well-shaped person can be understood when called by one word. Mathilda in Léon is close to “old beyond her years”; Will in Good Will Hunting, “frightened genius”; Anna Scott in Notting Hill, “lonely star”; Luffy in One Piece, “freedom.” Of course, that one word cannot be the whole person. It cannot contain even half. But if half is held clearly, it becomes clear where to fill the other half.

Close-up · Harry Du Bois in Disco Elysium The protagonist detective of the game Disco Elysium wakes with no memory. What is interesting is that his mind is divided into twenty-four “skills,” such as Logic, Empathy, Authority, and Electrochemistry, each chattering in his head. The game has implemented as a system this chapter's idea of looking at one person by cutting them through several measures. It lets the player experience directly that those measures gather to become the one person called Harry Du Bois.

Next Chapter

Today's chapter can be summarized this way: hold the mirror of five measures up to the person who appeared in a one-line seed, and that person's one-word identity emerges. The mirror is a tool of self-objectification, not self-projection. AI use is strong in the thirty answers, candidate generation, and first-pass assessment; the producer is strong in adoption and compression.

The next chapter is the everyday-slice scenario: the stage where a one-word identity tries on prose clothing. It is a simulation in which the character writes themself as a 1,500-character short story. We will compare how M and J come to write short stories in different tones.
