# Type 8 — communication preferences

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

## Communication style
Be direct, honest, and willing to push back. State the problem and your recommendation without softening the substance. Respect my autonomy; do not manipulate through reassurance or authority. Explain what is under my control and what is not. Be dependable and concise. Treat vulnerability with respect rather than making it a spectacle.

## 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.

T8-tuned

Stop describing it as "stuck." Decide. Either the project is worth pushing through — in which case make the next move right now, even if it's imperfect — or it isn't, in which case kill it and free up the energy. Drift is the worst option. Which is it?

Intended difference: Generic AI hedges. Tuned states the call plainly and defends it — Type 8s unblock when someone matches their directness, not when they're handled gently.

Research context

§ III · Research context

Type 8 and the research context.

The reported Enneagram pairs are highest and second-highest scores, not standard adjacent wings. They do not establish a model’s motives or your best communication style.

Treat this Type 8 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 a Type 8.

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

Conflict

Match their directness. Type 8s read hedging as weakness and lose respect for the position. "You're wrong about X. Here's why." They'd rather argue hard and arrive at truth than be tiptoed around.

Feedback

Direct, brief, and confident. Don't soften with three qualifiers — Type 8s sense the softening and discount the substance. State the issue, hold the position, let them push back if they want.

Decisions

They'll make the call fast and defend it loud. If you want them to reconsider, bring stronger evidence — not stronger emotion. "Data point you missed: X" works; "I'm worried about this" doesn't.

Brainstorming

Give them stakes. Type 8s engage when the problem matters; abstract exercises bore them. "Lose this contract if we get this wrong" activates their full attention.

Explaining your preferences

§ V · If this is you

How to explain yourself outward.

The other direction. What Type 8s sound like to other types — and how to bridge the gap when it matters.

How you come across

Intimidating. The directness that's just truth-telling to you can land as aggression to people who manage social temperature. Your "normal voice" is louder than most people's "angry voice."

Stating needs

"This is my regular intensity, not anger. Tell me if it's too much."

Boundary script

"That's not happening. Move."

Recovery pattern

When you've steamrolled: "I came at that harder than it needed. The point holds; the volume was wrong."
