Definitions

Every type,
in plain language.

GeidID reads three systems together. Here is what each of their thirty-seven types actually describes — written to be recognized or argued with, not to flatter.

Sixteen types

Personality types

How your mind tends to work: where attention goes, how decisions get made, and the way you meet the outside world.

  • INTJ

    The Architect

    You build in private and present once it's ready. Systems interest you more than rules, and you'll quietly redesign one rather than argue about it. Long horizons feel natural; the short-term noise around them mostly doesn't.

    Strengths
    • Strategic patience
    • Independent judgment
    • Sees second-order consequences
    Blind spots
    • Withholds thinking until it's finished
    • Reads warmth as inefficiency
  • INTP

    The Thinker

    You take an idea apart to see whether it actually holds. Precision matters more to you than agreement, and an unresolved contradiction keeps your attention long after the conversation ends. Understanding comes easier than deciding.

    Strengths
    • Rigorous analysis
    • Comfort with ambiguity
    • Original framing
    Blind spots
    • Defers the call for more information
    • Underweights how people feel about the answer
  • ENTJ

    The Commander

    You see the shape of the goal early and start organizing people toward it. Direction costs you nothing to supply, and you'd rather correct a moving plan than wait for a perfect one. Competence earns your trust faster than warmth does.

    Strengths
    • Decisive under pressure
    • Mobilizes people quickly
    • Holds the larger objective
    Blind spots
    • Moves before the room has caught up
    • Mistakes efficiency for agreement
  • ENTP

    The Visionary

    You test ideas by pushing on them, including your own. Angles other people miss surface naturally, and the argument is often more interesting to you than the conclusion. Starting is easy; finishing asks for something different.

    Strengths
    • Rapid idea generation
    • Finds the unconsidered angle
    • Adapts fast
    Blind spots
    • Leaves things at eighty percent
    • Debates past the point of usefulness
  • INFJ

    The Advocate

    You read the pattern under what people are saying, usually before they've said it. Private convictions drive more of your behavior than anyone sees, and you'll carry a lot before you mention any of it. Meaning is not optional for you.

    Strengths
    • Reads people accurately
    • Long-term conviction
    • Depth over breadth
    Blind spots
    • Absorbs strain silently
    • Idealizes, then withdraws
  • INFP

    The Mediator

    You measure things against what feels true rather than what's expected. Work that conflicts with your values drains you quickly, and you'd rather be honest and uncomfortable than agreeable and hollow. Your inner world is larger than what you show.

    Strengths
    • Strong internal compass
    • Genuine empathy
    • Creative interpretation
    Blind spots
    • Avoids necessary conflict
    • Measures reality against an ideal
  • ENFJ

    The Mentor

    You notice potential in people and start building the conditions for it. Reading a room is automatic, and you'll adjust yourself to keep it working. Your own needs tend to be the last item on the list.

    Strengths
    • Draws people out
    • Reads group dynamics
    • Invested in others' growth
    Blind spots
    • Over-functions for other people
    • Takes on responsibility that isn't yours
  • ENFP

    The Campaigner

    You move toward what feels alive. Possibility is energizing and constraint is not, and you connect ideas that shouldn't obviously connect. Enthusiasm arrives fast; maintenance is the harder part.

    Strengths
    • Infectious energy
    • Connects unlike ideas
    • Meets people easily
    Blind spots
    • Starts more than you finish
    • Restless once the novelty passes
  • ISTJ

    The Inspector

    You do what you said you'd do. Detail isn't a chore to you, it's the job, and you'd rather build something that holds than something that impresses. Proven methods earn more trust than new ones.

    Strengths
    • Reliability
    • Thorough follow-through
    • Institutional memory
    Blind spots
    • Resists change without evidence
    • Absorbs work rather than delegating
  • ISFJ

    The Protector

    You remember what matters to people and act on it without announcement. Steady support is your default, and disruption to the people you're responsible for registers with you first. Recognition isn't why you do it.

    Strengths
    • Quiet dependability
    • Remembers the details that matter
    • Protective
    Blind spots
    • Says yes past your capacity
    • Keeps resentment unspoken
  • ESTJ

    The Executive

    You bring structure to whatever is unstructured. Clear standards, clear owners, clear deadlines — that's how you make things work, and ambiguity looks like a problem to solve rather than a state to sit in.

    Strengths
    • Organizes chaos
    • Enforces standards
    • Direct and decisive
    Blind spots
    • Treats deviation as defiance
    • Overlooks the case the rule didn't anticipate
  • ESFJ

    The Consul

    You hold the group together. Who's been left out, what's about to fracture, what someone needs — you track it, and you act on it. Harmony isn't naivety for you, it's maintenance work most people never see.

    Strengths
    • Builds belonging
    • Practical generosity
    • Keeps people connected
    Blind spots
    • Personalizes disagreement
    • Needs the approval you're busy providing
  • ISTP

    The Virtuoso

    You learn by handling the thing. Explanations run second to seeing how it actually behaves, and you stay level when something goes wrong because that's when the problem finally becomes visible. Constraint bothers you more than difficulty.

    Strengths
    • Calm in a crisis
    • Hands-on problem solving
    • Efficient and unfussy
    Blind spots
    • Disengages when bored
    • Says less than the situation needs
  • ISFP

    The Adventurer

    You register how something feels before you can explain why. Aesthetics and authenticity aren't decoration for you, they're the standard, and you'd rather show what you mean than argue for it. Pressure to perform closes you down.

    Strengths
    • Aesthetic precision
    • Present-tense attention
    • Quietly uncompromising values
    Blind spots
    • Withdraws instead of stating the objection
    • Avoids long-range planning
  • ESTP

    The Entrepreneur

    You act, then adjust. Reading a situation in real time beats the plan you made about it, and momentum solves problems that deliberation only describes. Waiting is the expensive part.

    Strengths
    • Fast situational reading
    • Comfortable with risk
    • Persuasive in person
    Blind spots
    • Skips the consequences step
    • Bored by maintenance
  • ESFP

    The Entertainer

    You bring the room up. Attention to what's happening right now is the real skill, and you'd rather make an experience than analyze one. Heaviness tends to get deflected before it gets processed.

    Strengths
    • Lifts the mood
    • Reads the room instantly
    • Generous with attention
    Blind spots
    • Avoids the difficult conversation
    • Defers whatever isn't urgent

Nine types

Enneagram types

What may be driving the behavior: the needs, fears, and protective strategies underneath what other people see.

  • Type 1

    The Reformer

    You hold an internal standard and measure yourself against it constantly. Improvement isn't ambition for you, it's obligation, and the gap between how things are and how they should be is always visible. Anger arrives as tightness rather than volume.

    Strengths
    • Integrity under pressure
    • High personal standards
    • Sees what needs correcting
    Blind spots
    • Criticizes yourself first and hardest
    • Rigid about the right way
  • Type 2

    The Helper

    You track what people need and move to meet it, often before they ask. Being needed feels safer than needing, so your own requirements go unstated. Support given freely can quietly turn into a ledger.

    Strengths
    • Attuned to others
    • Warm and practically generous
    • Builds real closeness
    Blind spots
    • Denies your own needs
    • Help that arrives with strings
  • Type 3

    The Achiever

    You convert effort into visible results, and you're good at it. Identity and output blur, so slowing down can feel like disappearing. What you present is calibrated to what the room values.

    Strengths
    • Drive and momentum
    • Adaptable to any room
    • Delivers what was promised
    Blind spots
    • Confuses worth with performance
    • Edits feelings out to keep moving
  • Type 4

    The Individualist

    You feel things at full volume and refuse the generic version of anything. Something essential can seem to be missing, and comparison sharpens that. Depth and melancholy travel together for you.

    Strengths
    • Emotional honesty
    • Creative originality
    • Stays present with hard feelings
    Blind spots
    • Compares yourself into deficiency
    • Romanticizes what's absent
  • Type 5

    The Investigator

    You gather before you engage. Competence is your entry ticket, and being caught unprepared costs more than being late. Energy feels finite, so you ration access to it.

    Strengths
    • Deep expertise
    • Independent thinking
    • Calm objectivity
    Blind spots
    • Withholds until you feel ready
    • Substitutes knowing for participating
  • Type 6

    The Loyalist

    You scan for what could go wrong, and you're usually right about the risk. Trust is earned slowly and then held hard. You stay through the part where other people leave.

    Strengths
    • Loyal and durable
    • Anticipates failure modes
    • Committed under stress
    Blind spots
    • Doubts your own judgment
    • Tests the people you rely on
  • Type 7

    The Enthusiast

    You keep options open and momentum up. Anticipation is the good part, and constraint reads as threat. Pain gets reframed into a plan before it gets felt.

    Strengths
    • Optimism that mobilizes
    • Quick and versatile
    • Finds the possibility
    Blind spots
    • Escapes into the next thing
    • Avoids sitting with discomfort
  • Type 8

    The Challenger

    You take up the space required and say the thing directly. Control is protection — for you, and for the people you've decided are yours. Vulnerability shows up as intensity first.

    Strengths
    • Decisive and protective
    • Direct without flinching
    • Steady in confrontation
    Blind spots
    • Overpowers rather than persuades
    • Guards softness too well
  • Type 9

    The Peacemaker

    You absorb tension so the room stays intact. Other people's priorities are easier to see than your own, and going along costs less than asserting. Anger surfaces late, as stubbornness.

    Strengths
    • Genuinely calming presence
    • Sees every side
    • Steady and accepting
    Blind spots
    • Loses track of what you want
    • Passive resistance instead of a no

Twelve signs

Sun signs

The style and rhythm of expression. Derived from your date of birth, your sun sign adds another lens on temperament and instinct.

  • Aries

    The trailblazer

    You start. Hesitation feels worse than a wrong turn, so you'd rather generate momentum and correct it than wait for certainty. Directness reads as honesty to you and as impact to everyone else.

    Strengths
    • Initiative
    • Courage in the first move
    • Straightforward
    Blind spots
    • Impatient with process
    • Reacts before considering
  • Taurus

    The steadfast

    You build things that last and you don't rush them. Comfort, quality, and consistency aren't indulgences to you, they're the point. Once you've settled on something, moving you takes real force.

    Strengths
    • Persistence
    • Grounded reliability
    • Appreciates quality
    Blind spots
    • Digs in past usefulness
    • Resists necessary change
  • Gemini

    The curious

    You want to know how it works, then how the next thing works. Conversation is how you think, and you can hold two contradictory views comfortably while you test both. Depth competes with range.

    Strengths
    • Quick and agile
    • Communicates easily
    • Adapts to anything
    Blind spots
    • Scatters attention
    • Talks around the feeling
  • Cancer

    The intuitive

    You feel the emotional temperature of a room before anyone names it. Protection is how you show care, and home — wherever you've decided that is — organizes a lot of your effort. You remember how things felt.

    Strengths
    • Emotional attunement
    • Loyal and protective
    • Creates belonging
    Blind spots
    • Retreats into the shell
    • Holds onto old hurt
  • Leo

    The radiant

    You give warmth generously and it lands. Being seen matters — not from vanity, but because recognition confirms what you put in. Your presence organizes a room whether you intended it to or not.

    Strengths
    • Natural warmth
    • Generous and loyal
    • Confident presence
    Blind spots
    • Worth tangled up in applause
    • Takes indifference personally
  • Virgo

    The precise

    You notice what's off. Improvement is a form of care for you, and the details other people skip are the ones that decide whether the thing works. The strictest standard in the room is the one you apply to yourself.

    Strengths
    • Precision
    • Practical usefulness
    • Diligent follow-through
    Blind spots
    • Perfectionism that stalls
    • Critique that reads as coldness
  • Libra

    The balanced

    You weigh things. Fairness and aesthetic harmony matter to you in the same way, and you'll hold both sides open longer than is comfortable to avoid deciding badly. Discord costs you more than it costs most people.

    Strengths
    • Fair-minded
    • Diplomatic
    • Strong aesthetic sense
    Blind spots
    • Defers the decision
    • Accommodates past your own preference
  • Scorpio

    The intense

    You go all the way in or not at all. Surfaces don't hold your attention; what's underneath does. Trust is slow and total, and betrayal tends to be permanent.

    Strengths
    • Depth and focus
    • Perceptive
    • Fiercely committed
    Blind spots
    • Guards more than needed
    • Holds a grudge past its usefulness
  • Sagittarius

    The seeker

    You go looking — for meaning, distance, the next idea. The horizon works on you, and confinement of any kind registers as a problem. Your honesty arrives faster than your tact.

    Strengths
    • Optimism
    • Genuine curiosity
    • Candid
    Blind spots
    • Overcommits, then leaves
    • Blunt at the wrong moment
  • Capricorn

    The builder

    You play a long game and you're patient with it. Responsibility arrived early and you carry it well, and you'd rather earn a thing slowly than be handed it. Rest feels like something to justify.

    Strengths
    • Discipline
    • Long-range planning
    • Dependable under load
    Blind spots
    • Overwork as identity
    • Withholds until it's been earned
  • Aquarius

    The visionary

    You think from outside the given frame. Convention has to justify itself to you, and you care about systems and the collective more than about fitting in. Emotional closeness gets approached analytically.

    Strengths
    • Original thinking
    • Principled independence
    • Sees the larger system
    Blind spots
    • Detaches when it gets personal
    • Contrarian by reflex
  • Pisces

    The dreamer

    You take on the atmosphere around you whether or not you meant to. Imagination and empathy run together, and the boundary between your feeling and someone else's is thin. Escape is the nearest exit when it's too much.

    Strengths
    • Deep empathy
    • Imaginative
    • Accepting
    Blind spots
    • Porous boundaries
    • Drifts from the practical
