Mbti Typing

MBTI Typing

Core Stance

Use this skill to run a falsifiable personality-typing investigation, not a quick label assignment.

• Treat every type as a hypothesis with competing alternatives.
• Prefer "best-supported working formulation" over "this person is definitely X".
• Separate MBTI function-stack language, Big Five traits, Enneagram, attachment, culture, and development-stage explanations. Cross-check across frameworks, but do not pretend they are one theory.
• Do not use MBTI for clinical diagnosis, hiring, school admission, legal decisions, or any high-stakes gatekeeping.
• Let the subject correct the model. Corrections, contradictions, and "that wording is wrong" are high-value data, not noise.

Mode Selector

Choose the mode before doing substantive work:

If the request is broad, start with a short mode declaration and then proceed. Do not ask the user to choose a mode unless the target is genuinely ambiguous.

Low-Typing Question UX

Typing interviews should feel easy to answer, not like essay homework.

• Prefer recognition over recall: ask concrete scene questions with selectable options before asking for prose.
• Use the host's native question UI when it is actually available. Do not invent a host tool from a product name.
• Codex: use request_user_input only in Plan Mode or another context where it is present; otherwise use a compact text fallback.
• Claude Code: use AskUserQuestion only when it appears in the active tool list; otherwise use the compact fallback.
• Cursor: use AskQuestion only when it appears in the active tool list or active Cursor mode; otherwise use the compact fallback.
• opencode and headless CLI hosts: use compact A/B/C/D/E choices and proceed only when the user answers or when the assumption is low-risk and explicitly stated.
• For live typing questions, do not mark a recommended answer. All options should be plausible and similarly dignified so the user is not nudged toward a type.
• Unless the active host automatically adds a free-form "Other" field, make the final option Other / none of these - I will explain.
• Hide option-to-type mappings until after the user answers; explain the interpretation in the evidence ledger.
• When the user chooses Other, treat the correction as evidence and rewrite the next question instead of forcing the old frame.

Compact fallback format:

直接选 A/B/C/D/E；E = 以上都不是，我补充一句。每题可以只回一个字母。

Workflow

1. Intake the claim

   • Capture the target question: "What type am I?", "Am I INFP?", "ENTJ or INTJ?", "analyze these logs", etc.
   • Record prior claims and their source: self-test, friend, expert, work feedback, old reports.
   • If files are provided, read summaries first, then sample original turns around contradictions, reversals, and user corrections.

2. Build the candidate set

   • Include the claimed type, the strongest nearby alternatives, and at least one surface-lookalike that could explain the same behavior through a different mechanism.
   • Keep the active set small enough to reason about, usually 3-6 candidates.
   • Track priors explicitly when a prior claim matters, but call them heuristic unless they come from a validated instrument.

3. Create an evidence ledger

   • For every answer or excerpt, write the observed behavior, candidate explanations, supporting candidates, contradicting candidates, alternative non-type explanations, and the next question needed.
   • Use references/evidence-ledger-template.md for the ledger and final report skeleton.
   • For long or multi-round work, maintain a structured state using references/session-state.md and validate it with scripts/typing_session.py.
   • For quantitative updates, optionally use scripts/bayes_update.py; never present its output as psychometric certainty.

4. Interview adaptively

   • Ask 4-6 questions per round. Use forced-choice, ranking, or concrete scenario questions.
   • Default to low-typing choices: each question should be answerable by tapping or typing one option, with a final free-form escape hatch.
   • Avoid abstract self-label questions such as "Are you empathetic?" Prefer scenes: "When your partner cries during a conflict, what happens in your body first?"
   • Design each round against the current top conflict, not against all 16 types at once.
   • Load references/question-bank.md when drafting questions.

5. Run contradiction probes

   • If one type looks obvious, attack it before concluding.
   • Ask: "If this person were the runner-up type, which evidence would be easiest and hardest to explain?"
   • Do not close while the top two candidates share the same evidence source, function set, or social presentation.

6. Cross-check with modern trait evidence

   • Use Big Five as an independent reality check, especially for E/I, J/P, F/T, and A/T-like stability claims.
   • Use attachment, culture, life history, role demands, and current environment as alternative explanations for emotional expression, dominance, conflict style, and achievement pressure.
   • Load references/research-boundaries.md before citing validity, reliability, A/T, or psychometric claims.

7. Conclude with calibrated uncertainty

   • Give the leading type, runner-up types, decisive evidence, unresolved ambiguities, and specific falsifiers.
   • Use descriptive confidence by default: low, medium, medium-high, high. Use numeric percentages only when the user explicitly wants heuristic Bayesian notation.
   • Include the strongest "this could still be wrong if..." section.

Minimum Bar

A serious final typing must include:

• A candidate set with at least one plausible runner-up.
• At least two independent discriminators for the top-vs-runner-up distinction.
• One stress/recovery data point and one normal-state data point.
• One cross-framework check, usually Big Five; add attachment/culture/life-stage only when evidence warrants it.
• One section explaining what would falsify or revise the conclusion.
• One explicit boundary statement if the output could be mistaken for clinical, hiring, or deterministic advice.

Accuracy Rules

• Require at least two independent discriminators before separating adjacent types.
• Down-weight correlated evidence. Four questions that all measure "likes planning" are not four independent proof points.
• Separate normal state, stress state, recovery state, relationship state, and public-performance state.
• Do not overread a single dramatic story; ask for repeated patterns and counterexamples.
• Mark non-standard concepts as "working observation" or "clinical-style observation", not MBTI theory.
• Treat A/T as a 16Personalities-style stability/neuroticism lens, not official MBTI.
• Prefer "the evidence supports Te-Ni over Fi-Ne" to "you are ENTJ because you are efficient".
• If the user wants something "addictive", make the experience compelling through precision, progressive revelation, contradiction handling, and personally useful insight. Do not use manipulative retention loops, false certainty, or flattery.
