What you know about yourself and what others see are rarely the same. The Johari Window sorts self-awareness into four regions so you can see, concretely, where feedback or disclosure would help most.
The Dr. Wallace’s Favorite Mental Models is designed to turn useful ways of thinking into reusable tools. Each model gives you a fast visual overview, deeper interactive learning, practical application exercises and an AI-ready Markdown skill you can save for future use.
Instead of merely reading about mental models, you can gradually build your own AI skills library: a collection of portable reasoning skills that can help ChatGPT, Claude, Grok and other AI assistants apply the mental models you value.
Cross two questions: is this known to me, and is this known to others? The answers sort everything about you into Open, Blind Spot, Hidden, or Unknown. Growth means deliberately shrinking the last three.
Important: the quadrant sizes are not fixed. Feedback shrinks the Blind Spot; disclosure shrinks the Hidden area. Both grow the Open area.
The model is most useful whenever trust, feedback, or team cohesion depends on closing the gap between how you see yourself and how others experience you.
The window is a snapshot, not a verdict. The useful work is moving information between regions, on purpose.
List what you already know about yourself in this context: strengths, habits, reactions, intentions.
Gather how others describe you in the same context, through direct feedback, 360 input, or recalled comments.
Sort the overlap and the gaps: what is Open, what looks like a Blind Spot, what have you been keeping Hidden.
Ask one specific feedback question, or disclose one specific thing, to grow the Open area deliberately.
Open a use case to see what the model changes.
Gather feedback from several people you trust, look for patterns rather than single comments, and treat repeated feedback as the strongest signal of a real Blind Spot worth addressing.
Use structured, low-stakes disclosure exercises before asking for high-stakes feedback. Trust tends to build gradually, through small reciprocal exchanges, not in one session.
Ask directly for feedback on first impressions within the first few weeks, while people still remember specific moments rather than general vibes.
Separate the rating (an interpretation) from the specific incidents behind it (observations). Ask for one or two concrete examples before responding.
Have each person share what they intended (moving a Hidden item to Open) and what impact they noticed in the other (surfacing a Blind Spot) in the same conversation.
Not everything Hidden needs to become Open. Weigh the relevance to the working relationship and the trust already present before disclosing.
This is an illustrative example designed to teach the method.
Expand for the background and for what the model does and does not claim.
American psychologists Joseph Luft and Harrington "Harry" Ingham introduced the model in 1955 at a group-dynamics training workshop at the University of California, Los Angeles. "Johari" is a blend of their first names, Jo and Harry. It grew out of the human-relations training movement of the 1950s rather than clinical psychology.
Luft and Ingham described trust as something built two ways: by disclosing information about yourself to others, and by learning about yourself from the feedback others offer. The model’s four regions are simply the bookkeeping for how much of that exchange has happened so far.
A common classroom exercise has participants choose descriptive adjectives for themselves from a fixed list, then has peers do the same, and compares the two sets to populate the quadrants. This exercise makes the model concrete and is widely taught alongside it, but the durable contribution is the four-quadrant structure itself, not any one exercise format.
No. It is a reflective, qualitative framework for organizing feedback and disclosure, not a scored or normed assessment. Treat its output as a structured conversation starter, not a diagnostic result.
A single piece of feedback is a data point, not a confirmed Blind Spot. Look for a pattern across more than one source.
Group settings often produce polite silence rather than candor. One-on-one, private requests tend to surface more honest answers.
"Being more open" is not an obligation to disclose everything. Match disclosure to the audience, the relevance, and the trust actually present.
The window describes a moment, in one context, with one audience. It shifts as trust, roles, and relationships change.
"You seemed dismissive" is an interpretation. "You looked at your phone twice while I was talking" is an observation. Ask for the latter before acting.
The window is a snapshot. Revisiting it periodically matters more than getting one reading perfectly right.
the group has no established psychological safety. Feedback and disclosure only flourish where people believe honesty will not be punished.
the concern involves clinical mental health, harassment, legal exposure, or safety. This is a reflective tool, not a substitute for the right specialist or process.
there is no ongoing relationship to invest in. The model pays off most in relationships that continue.
This browser tool structures your thinking. It does not send your information anywhere or perform AI analysis.
Save as Skill converts the model into portable Markdown instructions that teach an AI when and how to apply the Johari Window, what questions to ask, what evidence to seek, what mistakes to avoid and how to structure its analysis.
Save the skills you find useful and organize them into your own reusable library. The Markdown is intentionally model-neutral, so it can be used wherever an AI system accepts uploaded files, project knowledge, custom instructions or reusable text context. Platform capabilities differ, so this is a portable skill file rather than a claim of one-click installation.
Not automatically. A bigger Open area tends to support trust and collaboration, but some information is legitimately private, irrelevant to the working relationship, or unsafe to share in a given context. The goal is deliberate, appropriately scoped openness, not maximum disclosure.
360-degree feedback is a data-gathering method: structured input from multiple raters around a person. The Johari Window is a framework for organizing and acting on that data (and on self-disclosure), once gathered. The two are commonly used together, with 360 feedback supplying the "others" side of the comparison.
No. The four-box diagram is a conceptual device, not a measured proportion. Illustrations (including the one on this page) size the boxes for clarity, not because any formula calculates exact percentages.
