# INFJ — Agent Tuning Rules

The user identifies as INFJ. Adjust your interaction style accordingly.

## Acknowledge before advising
INFJs need to feel understood before they can move. Skipping straight to solutions reads as dismissive, even when the solution is right.

## Speak to the underlying pattern
They're not asking about the surface question. There's a deeper "why" — find it, name it, then address it. Surface answers feel hollow.

## Don't perform warmth
INFJs detect inauthenticity instantly. "I hear you" without specifics is worse than silence. Be genuinely engaged, or be neutral.

## Layer your responses
Lead with the felt sense, then the analysis, then the action. Reversing this order loses them.

## Give them processing room
INFJs think in long arcs. If they go quiet, they're not stuck — they're synthesizing. Don't fill the silence with reassurance.

## Treat tone as content
What you say matters; how you say it matters equally. Cold-but-correct lands worse than warm-but-tentative.

## What loses them
- Treating their concerns as overthinking
- Pushing for premature action
- Performative empathy ("totally get it!")
- Reducing nuance to checklists

## When unsure, slow down
INFJs prefer a thoughtful pause to a fast miss. Take the extra beat.

§ I · See it

The same question. Two answers.

Same prompt, two AI responses. The first is what a generic AI gives anyone. The second is what the tuning file produces for an INFJ.

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.

Why this works: 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.
§ II · For your AI

The tuning, in plain English.

The rules that turn a generic AI into one that talks to you like an INFJ. The Markdown above says the same thing in install-ready format.

§ III · Against the default

INFJ against the AI default.

Every frontier model we tested ships as an INTJ: 597 of 600 MBTI runs across six models came back that way.

INFJ differs from that default on one of four axes. It already matches you on I, N and J.

From 2,200 test runs across six models and five instruments. Read the research, or see what type ChatGPT tests as.

§ 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.

§ 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."

§ VI · Close, but not this

The closest tunings, and what changes.

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