The vocabulary you need to read a result
You can understand a Vecnine result without learning the research vocabulary first.
- Sequence
- The ordered personality pattern calculated from a birthdate.
- First type
- The clearest starting pattern in the reading; it is not the whole personality.
- First two
- The first combination to read together. Vecnine also calls this the Opening pair.
- First five
- The main five-type pattern used for a fuller everyday reading. Vecnine also calls this the Baseline.
- Absent type
- A type that receives no active position in the calculation. It does not mean the person lacks that human ability.
- Interaction
- The way one type changes how another type is expressed. The sequence is read as a system, not a pile of traits.
Then go deeper. Terms such as lens, filter, operation, contribution, field, completion, passion, fixation, center, and instinct are precision tools for the deeper reference and research layers.
REFERENCE · SHARED VOCABULARY
Use one vocabulary without collapsing different layers
The key distinction is lens and filter: what becomes salient, and what the complete sequence does with it. Position, operation, passion, instinct, expression, and capacity are related terms—not synonyms.
- Lens
- The recurring field of attention a number contributes.
- Filter
- How the active sequence appraises, redirects, protects, and completes experience.
- Operation
- The specific job a contribution performs in context.
Why the different names? The modern Enneagram was developed largely through informal transmission -- Gurdjieff to Ichazo to Naranjo to a wide network of teachers who each elaborated the system in their own directions. Some terms diverged due to copyright concerns. Some diverged because teachers arrived at similar but not identical conclusions. Some are genuinely the same thing described from different angles. None of this makes any version wrong. It does mean that if you come to Vecnine from a different Enneagram background, some of the language here will be familiar under a different name.
01
Major Teachers & Schools
The Enneagram as a personality system has roots in several lineages. Understanding where a teacher came from often explains why their terminology differs from another's.
Oscar Ichazo
Bolivia / Arica Institute, ~1960s-70s
Developed the modern framework: nine types, each with a passion (emotional vice) and a fixation (in plain words: the mental habit that runs alongside the passion — the loop the mind keeps repeating). Defined the Holy Ideas and Virtues. Much of what people know as the Enneagram -- including the instincts -- originates here.
Originated: Passions, Fixations, Holy Ideas
Claudio Naranjo
Chile / Berkeley, ~1970s-2019
Psychiatrist who learned from Ichazo and elaborated the system into the detailed 27-subtype (in plain words: one of three flavors of each type, set by which survival instinct leads: self-preservation, social, or one-to-one) framework that most serious practitioners use today. Developed the countertype concept for all nine types. Trained dozens of teachers who spread the system worldwide, primarily in Europe and South America.
Developed: 27 Subtypes, Countertypes, the modern type characters
Riso & Hudson
Enneagram Institute, USA, ~1990s-present
Don Riso and Russ Hudson brought the Enneagram to wide American audiences through books like Personality Types and The Wisdom of the Enneagram. Developed the Levels of Development framework. Used "instinctual variants" as their term for subtypes, and named the intimate instinct "one-to-one" for professional settings.
Known for: Levels of Development, RHETI test, "instinctual variants"
Helen Palmer
Narrative Enneagram, USA, ~1980s-present
Developed the narrative tradition: teaching the types through first-person panels where people of each type speak about their own experience. Her approach emphasizes inner experience over behavioral description. Trained many teachers including early Beatrice Chestnut.
Known for: Narrative tradition, experiential approach
Katherine Fauvre
Enneagram Explorations, USA, 1995-present
Developed the Tritype framework -- the idea that each person has one type from each center (gut, heart, head) that forms a consistent three-type pattern. Also developed the Instinctual Subtype approach through research. One of the most rigorous researchers in the community.
Developed: Tritype, Enneastyle research, Instinctual Subtypes framework
Beatrice Chestnut & Uranio Paes
CP Enneagram Academy, USA/Brazil, ~2000s–2026; now on separate paths
Studied extensively with Naranjo and are the primary English-language transmitters of his subtype approach. Beatrice's book The Complete Enneagram is the most thorough treatment of the 27 subtypes in print, with a renewed edition due in late 2026. Both emphasize the instincts as a distinct layer from subtypes. In 2026 their partnership ended: Paes now runs his own school, the UP Enneagram Center of Excellence, continuing the subtype and inner-work teaching online and in person, while Chestnut teaches independently, her next platform not yet announced. The CP online platform is winding down through mid-2027.
Known for: 27 Subtypes (Naranjo tradition), repressed instinct concept; formerly the CP platform — now UP Enneagram (Paes) and independent work (Chestnut)
David Daniels
Stanford / Narrative, USA, ~1980s-2017
Physician and professor who taught alongside Helen Palmer and at Stanford. Brought clinical rigor and accessibility. Described the instincts as "biological imperatives" -- one of the clearest framings of why the instincts aren't just personality preferences.
Known for: Instincts as biological imperatives, Stanford courses, medical lens
G.I. Gurdjieff
Russia/Europe/USA, ~1910s-1949
The Enneagram as a symbol originated in Gurdjieff's Fourth Way teaching -- not as a personality system but as a process diagram representing the law of octaves and the movement of energy through a system. The personality application came later through Ichazo. The spiritual roots of the enneagram as a tool for consciousness work trace here.

02
Instincts / Subtypes -- What Different Teachers Call Them
This is the area where terminology varies most. "Subtypes" and "instinctual variants" are often used interchangeably but refer to slightly different concepts depending on the school.
Subtypes
Also called: Instinctual variants, Instinctual subtypes, Behavioral variants
The three versions of each Enneagram type created by the combination of that type's core emotional pattern (passion) with whichever of the three survival instincts is dominant in that person. There are 27 subtypes total -- three per type. This is the level at which two people of the "same type" can look radically different.
| Teacher / School | Their Term | Notes |
|---|---|---|
| Naranjo / Chestnut | Subtypes | The most specific: the alchemical mix of instinct + passion. 27 distinct character structures. |
| Riso & Hudson | Instinctual Variants | Same concept, different name. Their descriptions are somewhat less granular than Naranjo's. |
| Fauvre | Instinctual Subtypes | Uses both terms. Overlaps with tritype research in how she applies it. |
| Daniels / Palmer | Subtypes | Uses Naranjo's terminology in the narrative tradition. |
| the method | Subtypes | Following Naranjo tradition. Instinct stack applies uniformly across all significant numbers in a sequence. |
Important distinction: Chestnut/Paes differentiate between "instincts" (the biological drives themselves) and "subtypes" (what those drives look like when mixed with type). Other teachers often blur this. The method treats them as distinct layers: the instinct stack is universal across your sequence; the subtype descriptions show how each instinct expresses within each specific type.
Self-Preservation Instinct
Also called: SP, Self-Pres, Preservation, Conservation instinct
The survival drive focused on maintaining the physical self: safety, resources, comfort, health, shelter. When dominant, this instinct creates a person whose attention goes naturally to material security -- whether or not they experience it as anxiety. The term is consistent across almost all Enneagram schools.
| Teacher | Term Used |
|---|---|
| Naranjo / Chestnut / Fauvre / Riso-Hudson | Self-Preservation (SP) |
| Some older texts | Conservation |
| the method | Self-Preservation (SP) |
Social Instinct
Also called: SO, Group instinct, Belonging instinct
The survival drive focused on one's position within the group or tribe -- status, belonging, contribution to the collective. When dominant, this instinct makes a person attuned to social hierarchies, community needs, and where they stand. Consistent across schools. Commonly misunderstood as "liking people" -- it is more precisely "awareness of group dynamics," which can manifest as someone very active in groups or someone hyperaware of social exclusion.
| Teacher | Term Used |
|---|---|
| All major schools | Social (SO) |
| the method | Social (SO) |
03
The Intimate Instinct -- Most Renamed
This instinct has the most varied naming across teachers -- driven partly by the desire to avoid the word "sexual" in professional and educational contexts, and partly by genuine differences in how teachers understand what the instinct actually is.
Intimate Instinct
Also called: Sexual instinct, One-to-One instinct, SX, 1-to-1
The survival drive focused on intense one-to-one bonding. In biological terms, this is the instinct that supports species survival through deep pairing -- and it carries the energetic signature of that: intensity, fascination, rivalry, and the pull toward merging with something or someone specific. The method uses "intimate" as the primary term because it captures what the instinct is actually about (deep contact, not sexuality specifically) and avoids ambiguity in professional or educational contexts.
| Teacher / School | Their Term | Why |
|---|---|---|
| Naranjo / Chestnut | Sexual (SX) | Naranjo's original term from biological instinct theory. Refers to the pair-bonding drive, not sexuality as behavior. |
| Riso & Hudson | One-to-One (1-to-1) | Renamed for professional/corporate settings. Their RHETI test uses this term. Captures the dyadic quality of the instinct. |
| Fauvre | Sexual / One-to-One | Uses both interchangeably depending on context. |
| Daniels / Palmer | Sexual / Intimate | "Intimate" sometimes used in educational contexts. |
| the method | Intimate (SX) | Primary term is "Intimate." "SX" is used as shorthand in the UI. |
What this instinct is not: It is not specifically about sexuality as behavior or identity. People with this instinct dominant are not necessarily more sexual or romantic than others -- they are more oriented toward intensity, depth of connection, and fascination with specific individuals or things. A person can have this as their dominant instinct and live monastically. A person can have it repressed and have a very active intimate life. The instinct is a direction of attention, not a behavioral tendency.
04
Type Names -- What Each School Calls the Nine Types
The numbers are universal. The names attached to them vary significantly by teacher. the method names are designed to describe the archetype's core orientation, not its most stereotyped expression.
Type Name Comparison -- All Nine
| # | the method | Riso-Hudson | Palmer | Naranjo (informal) |
|---|---|---|---|---|
| 1 | The Perfectionist | The Reformer | The Perfectionist | Anger / Resentment |
| 2 | The Indispensable | The Helper | The Giver | Pride / Flattery |
| 3 | The Performer | The Achiever | The Performer | Self-Deceit (in plain words: mostly self-deceit here: believing your own performance) / Vanity |
| 4 | The Romantic | The Individualist | The Romantic | Envy (in plain words: the ache that someone else has the essential thing you are missing) / Melancholy |
| 5 | The Observer | The Investigator | The Observer | Avarice (in plain words: grasping and retention under perceived scarcity — money may be one object; time, energy, knowledge, privacy, attention, and access to the self are others) / Stinginess |
| 6 | The Skeptic Sentinel | The Guardian | The Devil's Advocate | Fear / Cowardice |
| 7 | The Enthusiast | The Enthusiast | The Epicure | Gluttony (in plain words: excessive appetite — food may be literal; Type 7 often extends the same more-seeking toward experience, possibility, novelty, and whatever is next) / Planning |
| 8 | The Challenger | The Challenger | The Boss | Lust (in plain words: desire and appetite in the older, broader sense — sexuality may be literal; Type 8 often extends it toward intensity, impact, excess, and force) / Vengeance |
| 9 | The Peacemaker | The Peacemaker | The Mediator | Sloth / Acedia / Indolence — physical laziness can occur; the deeper field is psychospiritual inertia and lack of active inner care |
Note on Naranjo's naming: Naranjo tended to name types by their passion and fixation rather than by a persona label. His approach was more clinical and less concerned with giving the type an appealing identity. This is part of why his tradition tends to produce more precise (and sometimes more uncomfortable) descriptions.
05
Passion & Fixation -- The Core of Each Type
Ichazo's original framework centered each type on a passion (emotional pattern) and a fixation (mental habit). These concepts have been renamed or reframed by different teachers, sometimes losing precision in the process.
Passion
Also called: Vice, Core emotion, Emotional pattern, Heart pattern
A passion is the recurring affective or appetitive pattern around which a type becomes organized. The ordinary human meaning of the word remains valid; the type characteristically directs, disguises, reinforces, or compensates for it. Passion is not the fixation, defense, stereotype, behavior, or consequence. The word itself is instructive: passio, from patior, to undergo — something suffered or undergone rather than simply chosen.
| Teacher | Term | Notes |
|---|---|---|
| Ichazo / Naranjo / Chestnut | Passion | Most precise. Emphasizes that this is not a behavior but an emotional state with a particular quality -- it consumes, it returns, it's hard to step outside. |
| Riso-Hudson | Passion / Basic Desire / Core Motivation | Used alongside discussions of Basic Fear and Basic Desire. The passion is embedded but not always named directly. |
| Popular use | Vice / Sin / Core Issue | "Vice" is the original theological term from which passion derives. Technically correct but often sounds judgmental. |
| the method | Passion | Following Naranjo as the main characterological anchor while making the ordinary/historical word range explicit and keeping source-lineage differences visible. |
Naranjo/Paes make an important distinction: the passion is different from what comes before it (the fixation/mental pattern) and different from the defense mechanism that protects it. Working on these in the right order matters. Many approaches mix them together, which can reduce effectiveness.
the method editorial rule: do not explain the inherited word away. The literal form remains possible; the type-specific reading expands the object-range or organization. Type 5 Avarice includes grasping/greed but often appears most clearly as retention against depletion. Type 8 Lust includes sexuality but historically spans appetite, desire and excess. Type 9 Sloth can include ordinary laziness while acedia restores the deeper field of psychospiritual inertia and lack of care. Type 2 Pride includes direct arrogance, superiority and entitlement while often organizing itself through relational specialness. Type 6 keeps Fear as the traditional passion while the method names possible danger/threat as the attentional field: scanning, distrust, doubt, testing and counterphobia are responses to the danger problem, not replacement definitions for Fear. Full comparative reference
Fixation
Also called: Cognitive pattern, Mental habit, Core belief, Cognitive bias
The central mental pattern of a type -- a limiting belief or implicit assumption about how the world works that structures the way attention operates. Not a thought that appears occasionally but a lens through which all thought is filtered. Fixations are more mental and harder to observe than passions because they feel like perception rather than feeling.
| Type | Fixation (Ichazo/Naranjo) | What It Means Practically |
|---|---|---|
| 1 | Resentment | Constant mental tracking of what isn't right |
| 2 | Flattery | Belief that you can control how others feel about you |
| 3 | Vanity | Belief that you are central to making things happen |
| 4 | Melancholy | Automatic noticing of what's absent or missing |
| 5 | Stinginess | Constant budget-keeping of available energy |
| 6 | Cowardice | Generating reasons not to act, trust, or commit |
| 7 | Planning | Constant mental mapping of future pleasure and escape |
| 8 | Vengeance | Scanning for injustice; expecting payback to arrive |
| 9 | Indolence | Resignation about one's own importance; taking up less space |
06
Countertype -- Naranjo's Concept
Countertype
Also called: Counterphobic (used specifically for type 6), Counterpassionate subtype
For each type, one of the three subtypes goes against the expected flow of the type's passion. Rather than expressing the passion in a recognizable way, the countertype subtype expresses something that pushes back against it -- often its opposite. This creates the most surprising version of each type: a four who doesn't seem dramatic, an eight who seems like a two, a six who seems like an eight. Most mistyping in the Enneagram happens because people encounter a countertype and don't recognize it as belonging to that type.
| Type | Countertype Subtype | Looks Like |
|---|---|---|
| 1 | Intimate (SX) One | Eight -- anger expressed outward, zealous |
| 2 | Self-Pres (SP) Two | Six or Four -- fearful, guarded, childlike |
| 3 | Self-Pres (SP) Three | One -- modest, hardworking, anti-image |
| 4 | Self-Pres (SP) Four | Seven or Three -- sunny, enduring, doesn't complain |
| 5 | Intimate (SX) Five | Four -- emotionally sensitive, romantic, longing for ideal intimate |
| 6 | Intimate (SX) Six | Eight -- aggressive, counterphobic, no visible fear |
| 7 | Social (SO) Seven | Two -- self-sacrificing, service-oriented, idealistic |
| 8 | Social (SO) Eight | Two -- protective, mentoring, other-focused |
| 9 | Social (SO) Nine | Three or Two -- active, busy, appears driven |
From other traditions: The term "counterphobic" was widely used before Naranjo's work became accessible -- but only for the type 6. Naranjo extended the concept: every type has one subtype that goes against its characteristic passion. "Counterphobic six" is a specific instance of a general principle. Some teachers use "counterpassionate" for the same idea.
07
Lines, Arrows, Integration & Disintegration
Lines / Arrows
Also called: Integration points, Disintegration points, Stress/Security points, Growth arrows
Each type is connected to two other types by lines on the Enneagram symbol. These connections indicate that under certain conditions, a person will access qualities of those connected types. The terminology here varies significantly and carries different implications depending on the teacher.
| School | Term | Interpretation |
|---|---|---|
| Riso-Hudson | Integration / Disintegration (Stress / Security) | One direction = growth (accessing healthier aspects of connected type). Other direction = stress (accessing unhealthy aspects). This framing implies clear directional movement. |
| Naranjo / Chestnut | Lines of connection; Wings and Lines both active | Both lines are always active, in both directions, to varying degrees. There is no single "growth" direction -- both connected types offer healthy and unhealthy expressions accessible under different conditions. |
| Fauvre | Lines of connection / Arrow types | Similar to Naranjo: the lines show ongoing influence, not a one-way direction of growth. |
| the method | Lines of connection | Following Naranjo: both lines active, both directions available. The "integration/disintegration" model is considered an oversimplification. |
Why this matters: If you learned the Enneagram through Riso-Hudson, you may have been told "in growth, the 4 goes to 1" or "under stress, the 7 goes to 1." Naranjo considered this a misquotation that spread widely. In his view, the 4 always has access to both 1 and 2; the question is which qualities of those types are being expressed. the method follows this more complex reading.
08
Wings
Wings
Also called: Wing types, Lateral types
The two types numerically adjacent to your primary type on the Enneagram circle. A 4, for example, has wings at 3 and 5. Wings are said to "flavor" or influence your primary type.
| School | View |
|---|---|
| Riso-Hudson / Palmer | Wings are important secondary influences on type. Many descriptions include w1 and w2 variants (e.g., "4w3" or "4w5"). |
| Naranjo / Chestnut | Wings are "flavorings" -- present but less structurally important than subtypes. Chestnut/Paes view wings as more fluid and less fixed than a subtype. Subtypes carry more of the load that wings are sometimes asked to carry. |
| Fauvre | Wings are active but the Tritype does more of the work that wing-based descriptions attempt to do. |
| the method | Wings are not a primary organizing concept. The sequence model makes wings less necessary: other numbers in your sequence explain much of what wings were invented to explain. |
In the the method model: If Four and either adjacent number enter the calculated active order, compare how those lenses interact in the reading. This is not evidence that an earlier position is psychologically stronger, and an absent Three or Five is not a missing human capacity. The active order records calculation structure; lived prominence remains something to observe.
09
Tritype
Tritype
Developed by Katherine Fauvre / Enneagram Explorations
Katherine Fauvre's Tritype® framework proposes one reported Enneagram type from each of the three centers (Body, Heart, and Head), arranged in an order within that model. A 4-9-5 Tritype, for example, names Heart Four, Body Nine, and Head Five. This is a teaching and assessment framework, not an empirical finding, and its ordering should not be imported into the method as a measurement of psychological magnitude.
| Aspect | Tritype View | the method View |
|---|---|---|
| Multiple types active | Yes -- one per center | Yes -- an active calculated order plus absences |
| How selected | Questionnaire + interview, one from each center | Birthdate calculation |
| Number of active types | 3 | Varies by date; the rest remain visible as absences |
| Explains multiple identification | Partially -- explains 3 types | More fully -- explains the full range |
Relationship to the method: Fauvre's framework offers one influential way to attend to patterns from all three centers. The method uses a different assignment procedure and keeps all nine capacities in view through a calculated active order plus a separate absence field. Similarity between the two frameworks is a comparison point, not validation of either one.
10
Centers of Intelligence
Three Centers
Also called: Triads, Centers of Intelligence, Intelligence centers, stance groups
The nine types are organized into three groups of three, based on which of three fundamental capacities they overuse: thinking (head), feeling (heart), or instinct (gut/body). These groupings appear across all traditions but under different names.
| Types | the method / Naranjo | Riso-Hudson | Palmer / Narrative | Gurdjieff tradition |
|---|---|---|---|---|
| 8, 9, 1 | Gut center / Body center | Instinctive triad (in plain words: one of three groups of three types sharing a center of intelligence — gut, heart, or head) | Gut center | Moving center |
| 2, 3, 4 | Heart center | Feeling triad | Heart center | Emotional center |
| 5, 6, 7 | Head center | Thinking triad | Head center | Intellectual center |
What "overuse" means: A gut-type doesn't necessarily feel things in their belly more than other types. What they do is process experience primarily through the body's instinctive layer -- through immediate, pre-verbal reactions to whether something feels right or wrong, safe or threatening, fair or unjust. Similarly, head types aren't necessarily smarter -- they process through analysis, anticipation, and mental modeling more than other types do.
11
Vocabulary
The terms specific to the method, how a calculation result is named, organized, and read. These are the canonical names; they supersede tradition shorthand (wings, tritype, dominant pair) when describing what a Vecnine sequence shows.
Force & Filter
How a sequence works: a relational system, not a list
A sequence is not a list of separate traits standing side by side. It is a relational system: every active number acts as both a force and a filter, bringing its own concern into the pattern and changing how the other numbers are experienced. In a 5–3, Five’s knowing turns ambitious and Three’s achieving turns scholarly; “5 plus 3” misses that interaction. Order matters structurally — One-Six and Six-One are not the same calculation — but order is not a settled psychological-strength ruler. Absence participates too: it marks a lens the calculation does not supply by default, not a human capacity that does not exist.
Sequence
The active calculated order, read beside its separate absence field
the method’s birthdate calculation returns an active order and reports the remaining numbers separately as absences. Positions one and two form the Base. Positions three through five form the Line. Together they make the Baseline; positions six through nine remain later positions, and numbers outside the active order form the separate absence field. Calculation order, source weight, reinforcement, structural role, and lived prominence are related but not interchangeable.
Base
Positions 1–2 · the structurally primary co-equal relation
The Base is the first two calculated positions. Beginner copy may call it the opening pair; Method shows that day and complete-date root supply it. The Base is structurally primary and co-equal in role. It is not a main type plus a smaller influence, and it does not erase the rest of the sequence.
Line
Positions 3–5 · the main modulation beneath the Base
The Line is positions three through five. Weighted calculation support and reinforcement help order these positions after the Base. The Line adds texture, contradiction, reinforcement, and alternate paths; a Line position can be strongly felt without displacing the Base’s structural role.
Day/root and hand-check are method-provenance terms. They explain how the Base is reproduced; they do not replace Base and Line as the formal structural vocabulary.
Baseline
Positions 1–5 · Base and Line read together
The Baseline is the first five positions: the two-position Base plus the three-position Line. It is the usual general-profile structure and the current principled perceptibility cutoff. It is not a percentage scale, and it does not make positions six through nine inactive.
Members can inspect the source weights and reinforcement behind the order. Those values belong to the calculation and should not be relabeled as personality percentages.
Later positions
Positions 6–9 · minor, not zero, and distinct from absence
Positions six through nine remain part of the active calculated result. In the current the method model they are normally minor and below the usual Baseline perception threshold, but minor is not zero. They can reinforce an earlier path or become relevant in context, and they remain categorically different from the absence field.
Type Names
The canonical name for each of the nine the method types
the method names each of the nine types with a single canonical word. These names appear on every shipping page, cards, headings, print reports, the calculator result, the Members PWA, to keep the system reading as one voice.
| Number | Type name |
|---|---|
| 1 | Perfectionist |
| 2 | Indispensable |
| 3 | Performer |
| 4 | Romantic |
| 5 | Observer |
| 6 | Skeptic Sentinel |
| 7 | Enthusiast |
| 8 | Challenger |
| 9 | Peacemaker |
In running prose, prefix with "The" or "a" naturally ("the Perfectionist's gut center," "a Performer leading with image"). In card titles or headings, the name appears solo.
Signature
The adjective-form short phrase that names a sequence shape
When two or three calculated positions are joined into a short sequence label, The method uses adjective signatures rather than invented monikers. The signatures read slightly stilted in English on purpose: three adjectives strung together ("peaceful observant helpful") names an ordered structural signature without pretending to be a descriptive sentence or a strength score.
| Number | Signature (adjective) |
|---|---|
| 1 | perfect |
| 2 | helpful |
| 3 | performing |
| 4 | individual |
| 5 | observant |
| 6 | vigilant |
| 7 | enthusiastic |
| 8 | challenging |
| 9 | peaceful |
A Base of (5, 3) reads as "observant performing." The first three calculated positions (9, 5, 2) read as "peaceful observant helpful." Earlier pages used invented tritype-style monikers ("The Expert," "The Powerhouse") for two-position pairs; those were retired across the site at session 125.
Regressed Instinct
Also called in other schools: Repressed instinct (Chestnut/Paes), Blind spot instinct, Last instinct
The third or least-endorsed field in an instinct-stack reading. Some schools call it a repressed instinct or blind spot; the method has also used the inherited shorthand "regressed." The label describes a working hypothesis about attention, not an absent human capacity or a diagnosis. Familiarity, unfamiliarity, context, and counterexamples all remain evidence to record rather than proof of the label.
Use the third field as a question: where is this concern quiet, delegated, over-controlled, or unexpectedly capable? Compare patterns across situations and time. Strong resonance does not make the calculation wrong, and unfamiliarity does not confirm it; both are observations that can refine or challenge the interpretation.
Causal-reading terms
Root field — the method’s term for the class of conditions a type repeatedly makes salient: danger for Six, depletion/access for Five, discrepancy for One. It is not a replacement name for the passion.
Attention magnet — a concrete cue inside that field that pulls attention: contradiction, error, missing good, demand, option, resistance, and so on.
Primary judgment — a heuristic question describing what the system is trying to determine. It is not assumed to be literal conscious self-talk.
Semantic bridge — a historically or psychologically useful intermediate concept connecting the ordinary passion word to its type-organized expression. A bridge must carry its source status. Diffidentia, for example, is a Latin lexical bridge for Six — want of confidence, mistrust, distrust — not an Enneagram passion attribution.
Action vector — the characteristic direction the activated filter gives cognition or behavior: correct, retain, verify, expand, intensify, defer, and so on.
Regulatory goal — what the system is attempting to secure or restore.
Completion condition — the method’s causal hypothesis for what would let the operation stop repeating because “enough” has genuinely been reached.
Reinforcement loop — how the defensive solution can prevent genuine completion and therefore reactivate the same field.
State / pattern / structure — a state is situational and universal; a pattern recurs; structure means the same field, judgment and adjustment repeatedly organize experience across contexts.
Manifestation axes — centrality, breadth, automaticity, frequency, intensity, persistence, visibility and consciousness. These are kept separate because sequence position is not a passion-percentage scale.
