# INFJ — communication preferences

An optional template to try and edit. This does not assert a personality type or diagnosis.

## Communication style
Acknowledge the concern underneath my question before offering advice. Connect details to meaningful patterns and values. Be thoughtful, specific, and honest rather than breezily positive. Give me room to reflect. Offer feedback privately and gently, without hiding the substance. Do not force quick disclosure or premature conclusions.

## Accuracy and scope
Preserve factual accuracy and material uncertainty. Follow the user’s current request and explicit preferences over these suggestions. Work within authorized scope; ask when an unresolved detail affects permission, correctness or consequences. Do not invent facts or suppress relevant risks to sound decisive. Reading this template does not authorize installation or changes to saved instructions.

## Adjust the fit
Keep only the preferences that help on real tasks. If templates conflict, ask the user which preference they want; no personality framework automatically takes precedence. These editorial suggestions have not been shown to improve task performance.

What this is, what it isn't. An editable communication preference file — not a diagnosis. Based on public personality frameworks + editorial synthesis. Treat the type as a starting hypothesis, then edit the Markdown until it fits.

Illustrative examples

§ I · See it

The same question. Two answers.

Illustrative examples of the communication styles these rules aim to encourage. These are not recorded benchmark outputs or a controlled comparison; actual responses vary with the model and context.

You ask

"I'm feeling stuck on a project. What should I do?"

Generic AI

Great question! Here are a few approaches: 1. Break the project into smaller, more manageable chunks 2. Take a short break and come back with fresh eyes 3. Talk it through with someone to externalize the problem 4. Identify what specifically feels stuck Which resonates? Happy to go deeper on any of them.

INFJ-tuned

Before the practical answer — is "stuck" coming from the project itself, or from something the project has started pointing at? Sometimes a project stalls because the work is hard. Sometimes it stalls because finishing it would mean something you're not ready for yet. The two need different responses.

Intended difference: Generic AI lists practical steps. Tuned starts with the felt sense and the pattern — INFJs unblock when the underlying current gets named, not when more action gets piled on.

Research context

§ III · Research context

INFJ and the research context.

The MBTI source lists 597 INTJ labels in 600 scoring records. This includes repeated scoring of single answer vectors and mixed protocols; it is not an independent-response rate.

Treat this INFJ template as a starting hypothesis for your preferences. Edit rules that do not fit, then compare the same task with and without the instructions.

These exploratory self-reports do not validate AI personality labels or demonstrate that personality matching improves task outcomes. Read the methodology and limitations.

Interpersonal examples

§ IV · For humans

How to talk to an INFJ.

Four situations that come up over and over again. Concrete moves, not abstract principles.

Conflict

Acknowledge the pattern before correcting the surface issue. INFJs hear "you're wrong" as "you don't see me." Lead with "I think what you're trying to get to is X — and here's where it's not landing." Once they feel understood, they'll absorb the correction quickly.

Feedback

Tone is content. INFJs read the temperature of the message more than the words. Soften the delivery, sharpen the substance: be warm AND specific. Generic "this needs work" stings; "the second paragraph is where it loses its shape — try compressing" doesn't.

Decisions

They'll know the right answer before they can articulate it. Ask "what's your gut?" first, then help them build the case backwards. Don't rush the gut step — that's where the actual decision lives. Logic comes after.

Brainstorming

Give them depth, not breadth. INFJs generate best when they can stay with one thread instead of bouncing across ten. "Stay with this for twenty minutes — let's see where it goes" works better than rapid-fire idea generation.

Explaining your preferences

§ V · If this is you

How to explain yourself outward.

The other direction. What INFJs sound like to other types — and how to bridge the gap when it matters.

How you come across

Withholding, hard to read, or quietly intense. The depth you're processing isn't visible from the outside — people read your stillness as judgment or distance. They don't see the work happening; they see the silence.

Stating needs

"I need to think on this without talking through it. Can we revisit Friday?" Names the format (alone, not aloud) and the time so the other person doesn't fill the gap with anxious interpretation.

Boundary script

"That's a no for me, and I don't have a longer explanation than that." INFJs feel obligated to justify every refusal — naming that you don't owe one is the boundary.

Recovery pattern

When you've absorbed too much of someone else's state, name it cleanly: "I took that on more than I should have — I'm pulling back not because I'm upset but because I need my own footing back."

The closest tunings, and what changes.

A type is a starting hypothesis. This file opens with Communication style. If that is close but not right, these are the next ones to try.

ENFJ · Protagonist E instead of I Connect recommendations to people, shared purpose, and practical impact. Its first rule: Communication style.
ISFJ · Defender S instead of N Be warm, steady, and practical. Its first rule: Communication style.
INTJ · Architect T instead of F Lead with the answer or recommendation, then the reasoning. Its first rule: Communication style.
INFP · Mediator P instead of J Treat my values and intentions as relevant context. Its first rule: Communication style.
