# Johari Window: A Feedback Exercise, Not a Personality Test

The Johari Window is a simple grid for preparing a feedback conversation. It compares what a person knows about themselves with what others perceive. It can help a team discuss a concrete situation, provided that a perception is never turned into a fact about a person.

The model is attributed to Joseph Luft and Harrington Ingham and was published in 1955 through the Western Training Laboratory at UCLA. The [original bibliographic record](https://bibbase.org/network/publication/ingham-luft-thejohariwindowagraphicmodelofinterpersonalawareness-1955) preserves the title, authors, and institution. A [Health Education England methodological sheet](https://www.hee.nhs.uk/sites/default/files/documents/Johari%20window.pdf) presents the four areas for feedback work, while the institutional training and dialogue resources use it as a facilitation aid: [KAICIID’s dialogue manual](https://www.kaiciid.org/sites/default/files/dialogue_for_peace_manual_english_reduced_0.pdf) stresses consent, a participant’s pace of disclosure, and confidentiality.

The value of the exercise is not to reveal who someone really is. It is to make a perception discussable and let the person choose what to explore.

## Four areas, without filling the unknown

The grid crosses two questions: Is it known to the person? Is it known to other participants?

| Area | What it contains | Working rule |
|---|---|---|
| Open | What the person and others recognise in the situation | Describe facts and context |
| Blind | What others say they observed but the person had not noticed | Offer a perception, never a verdict |
| Hidden | What the person knows but has not chosen to share | Disclosure remains voluntary |
| Unknown | What neither the person nor the group knows yet | Leave it blank; record a possible question |

The open area should not contain broad traits such as “reliable” or “difficult”. It can contain situated behaviour: “during the last briefing, I restated the instruction and two people asked for clarification.” The blind area does not mean that other people are right. It means that a perception exists and may be examined if the person wants to.

The hidden area must not be forced in the name of transparency. Someone may choose not to share an experience or feeling. The unknown area remains genuinely unknown. No model, facilitator, or tool should invent a psychological hypothesis for it.

## Set the contract before feedback

A voluntary exercise starts with a clear contract. Who is taking part? Which behaviour or situation is being discussed? What will be written? Who may read the notes? What can the person decline?

In a team setting, an employer may provide time for development; it should not force an employee to reveal personal information or publish a grid about everyone. The Johari Window is not an HR evaluation, ranking tool, or proof of authenticity. Every participant should be able to withdraw, limit the topic, and correct a formulation.

The facilitator also sets the expected language. Speak from an observation: “in Tuesday’s meeting, I heard…” rather than “you are…”. Separate what was seen, what was understood, and what remains an interpretation. This discipline matters more than the diagram.

## Choose one observable situation

A group cannot give useful feedback about an entire personality. Choose a recent, bounded situation: a handover, a briefing, a decision prepared together, or a disagreement in a meeting.

Ask the person to describe:

- what they wanted to achieve;
- what they did or said;
- what they observed afterwards;
- what they would like to understand or try.

Avoid labels and diagnoses. “I want to understand why questions decrease after I change an instruction” is workable. “I want to know whether I am a good leader” is not yet specific enough.

A participant can then share feedback tied to the scene: “When the instruction changed twice, I waited before asking because I no longer knew which point came first.” This is an effect perceived in one situation. It does not classify the person.

## Run the feedback in five movements

### 1. Confirm consent

The person confirms the topic and acceptable level of detail. The facilitator checks that everyone knows what will remain private and what may be recorded.

### 2. Describe before interpreting

Participants give a concrete example situated in time. They use “I” and avoid generalisations. A pause lets the person hear the feedback without having to respond immediately.

### 3. Ask for clarification

The person may ask, “When did you notice that?” or “What made you see it that way?” The participant can clarify their experience but should not defend a label.

### 4. Accept, qualify, or decline

Feedback is not an instruction. The person may not recognise the perception, may want to check the context, or may decline to continue. The group keeps perception separate from an established fact.

### 5. Choose a follow-up

The person chooses what to test: request a rephrasing, change an instruction, or observe one moment. If no follow-up is useful, the conversation can stop. The window does not have to “grow” for the exercise to succeed.

## A fictional example: preparing a training briefing

A trainer is preparing a briefing for a group of managers. After one session, she wants to understand why questions decreased when she changed the order of activities. She invites three colleagues who volunteer; she does not ask them to assess her personality.

She describes the sequence and her intention: save participants time. One colleague says, “When the steps changed, I waited before interrupting because I wanted to check the new logic.” Another adds, “The written instruction was clear, but I did not know which part came first.” These comments enter the blind area as situation-bound perceptions, not conclusions about the trainer.

The trainer asks whether the same thing happened in other sessions. The colleagues say no. She chooses a limited test: state the first activity’s purpose aloud and ask one participant to rephrase it. The record separates observation, working hypothesis, and what is still unknown. It includes no score, personality note, or named colleague made public.

## Write a trace that respects people

A follow-up sheet can contain:

| Field | Example |
|---|---|
| Situation | 12 September briefing, activities reordered |
| Observation | Two colleagues waited before asking a question |
| Reported perception | The priority of the first step seemed unclear |
| Person’s response | Plausible hypothesis; context needs checking |
| Chosen follow-up | Ask for the objective to be rephrased next time |
| Preserved unknown | Effect on participants who were not present |
| Access | Notes visible only to the person and facilitator |

Do not publish a named grid of an entire team’s “blind areas”. Even a development exercise can become exposure or pressure. Keep quotations minimal, contextualised, and available to the person concerned where possible.

The guide on [personality tests](https://harmate.com/en/blog/mbti-disc-big-five-why-personality-tests-are-not-enough-to-build-high-performing-teams) explains why a static label is not enough to understand collective work. The Johari Window must not become another label: it opens a conversation about a situation and asks whether a check is useful.

## What the exercise cannot establish

A colleague’s perception does not prove a trait, intention, or competence. Silence can have several explanations. A person who is absent cannot be placed in an area because the group believes it knows what they think. The model does not measure trust, personality, performance, or relationship quality.

The exercise can also fail when hierarchy is present, the topic is too sensitive, or the person cannot genuinely decline. Change the frame or do not use the window in those cases. A [World Café](https://harmate.com/en/blog/world-café-method-90-minute-agenda-and-15-facilitation-questions) serves a different intention: moving a question between tables and harvesting contributions, not mapping perceptions around one person.

## Where Harmate may help, late in the process

Harmate can collect or import authorised responses, preserve wording and context, connect themes or contradictions to verbatim evidence, and prepare a report that the person can review. It does not fill the unknown area, infer a trait, choose who should receive feedback, or replace the trust required for the exercise.

The Johari Window is therefore a voluntary development aid. Keep the four areas modest, anchor feedback in one situation, and let the person decide what to share, check, or leave open.
