The Johari Window: the framework behind Tuko
The four-pane model behind every conversation — what you share, what stays hidden, what you don’t see — and how Tuko quietly uses it.
You’ve probably noticed that conversations with your child have a texture to them. Some stay on safe, familiar ground. Others surprise you both. And occasionally something comes up that neither of you expected: a feeling or a thought that wasn’t there until someone said it out loud.
That range isn’t random. There’s a framework that explains it, and it’s the model that shapes how Tuko works behind the scenes.
Where it comes from
The Johari Window was created in 1955 by two psychologists, Joseph Luft and Harrington Ingham. The name is just their first names squashed together (Jo and Hari). They built it as a tool for group therapy, a way of mapping what people know about each other and what they don’t.
The idea is straightforward. In any relationship, some things are known to both people, some are known to only one, and some haven’t been discovered by either. Luft and Ingham drew these as four quadrants, like panes in a window. The model caught on in organisational psychology, team building, and counselling. It turns out to work just as well for how you talk to your kids.
The four quadrants
The small grid on each card shows where that pane sits in the window.
YOU KNOWYOUR CHILD KNOWS
The open area
The stuff you both know. Their favourite food. Your weekend routine. The family jokes. Most daily conversation sits here, and that’s fine. The open area is where trust accumulates, proof that you notice each other and remember.
The trap is staying here permanently. If every conversation covers familiar ground, the relationship can feel close without actually growing.
YOU KNOWYOUR CHILD DOESN’T KNOW YET
The blind spot
What you can see in your child that they haven’t recognised in themselves. The kindness they show without thinking. The way they always step up when a friend is upset. The talent they’re quietly developing.
You get to be a mirror here. “I’ve noticed you always check on your sister when she’s sad. That’s a really kind instinct.” That kind of reflection shows your child something true about themselves.
It requires care, though. The blind spot is also where you might see things your child isn’t ready to hear. There’s a difference between “I’ve noticed you get really quiet around new people” and “You need to be more confident.” One is an observation. The other is an instruction.
YOU DON’T KNOW YETYOUR CHILD KNOWS
The hidden area
What your child knows about themselves but hasn’t told you. The friendship that’s gone wrong. The worry they carry into school every morning. The ambition they’re too embarrassed to say out loud.
When a child shares something from here, pay attention. It means they trust you enough to be vulnerable. How you respond matters more than what you say. Stay calm. Stay curious. Don’t rush to fix it.
This works in reverse too. You have thoughts and feelings you haven’t shared with your child. Sometimes going first, sharing something honest about yourself, gives them permission to do the same.
YOU DON’T KNOW YETYOUR CHILD DOESN’T KNOW YET
The unknown area
Everything neither of you has discovered yet. How they’ll handle a challenge they haven’t met. Talents they haven’t tried. The person they’re becoming. This is the part that stays full of surprise, and it’s why playful, open-ended questions matter. They create the conditions for something new to come out.
Your child says something that catches you both off guard. You share a thought you didn’t know you had. These moments can’t be planned, but a good question can make them more likely.
How Tuko uses this
The framework shapes two layers of how the app picks questions: the depth categories and the intent system.
Depth categories
Tuko’s four categories tend towards different quadrants.
Fun
Fun cards reinforce the open area. Shared laughter, familiar territory, trust building. But pay attention when a lighthearted question gets a surprisingly thoughtful answer. That’s the unknown area surfacing.
Light
Light cards nudge towards the hidden area and the blind spot. They invite small stories and observations that sit just below the surface. These are often the ones that prompt a child to share something they’ve been sitting on.
Deep
Deep cards go into the hidden area and the unknown. They ask about feelings, identity, and meaning. They give your child language for things they might not have put into words before, and they give you the chance to reflect something back they hadn’t seen in themselves.
Wacky
Wacky cards play in the unknown area through imagination. “If you could invent a new holiday, what would it celebrate?” sounds daft, but the answer often reveals something real about what a child values. When something is silly enough, there’s no wrong answer. That’s why wacky questions work so well with younger kids and reluctant teens.
The intent layer: Identity, Belonging, Purpose
Luft and Ingham’s model describes what kind of knowledge exists in a relationship (shared, hidden, blind, unknown), but it says nothing about what that knowledge is about. You could have a wide open area and still never talk about anything that matters.
Tuko addresses this by layering three intents across the four quadrants.
The rotation across all three intents means a session doesn’t just go deeper. It goes wider. Over ten questions, your child explores who they are, where they belong, and what they care about, across all four quadrants.
Identity
Identity questions are about “Who am I?” They help your child explore their character, preferences, and strengths. From the open area: “What’s something you’re really good at?” From the hidden area: “What’s something about yourself that most people don’t know?”
Belonging
Belonging questions are about “Where do I fit?” Relationships, family, friendship, community. From the blind spot, you might share an observation: “I’ve noticed your friends always look to you when they need to decide something. What do you think that’s about?”
Purpose
Purpose questions are about “Why am I here?” Values, meaning, what matters. From the unknown area: “If you could change one thing about the world, where would you start?” The answer might surprise your child as much as it surprises you.
Identity
Identity questions are about “Who am I?” They help your child explore their character, preferences, and strengths. From the open area: “What’s something you’re really good at?” From the hidden area: “What’s something about yourself that most people don’t know?”
Belonging
Belonging questions are about “Where do I fit?” Relationships, family, friendship, community. From the blind spot, you might share an observation: “I’ve noticed your friends always look to you when they need to decide something. What do you think that’s about?”
Purpose
Purpose questions are about “Why am I here?” Values, meaning, what matters. From the unknown area: “If you could change one thing about the world, where would you start?” The answer might surprise your child as much as it surprises you.
How this works in practice
You don’t need to think about any of this while using the app. Tuko handles the rotation automatically.
In Guided mode, the app progresses through Fun, Light, and Deep over a session, adjusting based on how things are going. Within each category it rotates through Identity, Belonging, and Purpose so that no single theme takes over. It also tracks the last 70 questions you’ve seen and avoids repeating them.
A ten-question session will naturally cover all three intents and touch several quadrants, without anyone steering it. The conversation just feels like it has range, and you never have to think about why.
In Focus mode you choose the depth and the app handles the rest. Even within a single category like Deep, the intent rotation keeps things moving across identity, belonging, and purpose rather than circling the same ground.
Why any of this matters
You don’t need to memorise quadrants or plan your Tuesday evening around the Johari Window. But knowing the framework exists changes how you listen.
You start to notice when a conversation is covering new ground versus going over old territory. You notice when your child volunteers something they’ve never said before, and you understand why that moment feels different. You catch yourself reflecting something back to them and realise you’re doing something useful, even if you couldn’t have named it.
None of that requires a psychology degree. It just requires paying attention, which is the thing that actually makes conversations good.
Your turn
Next time you’re chatting with your child, notice which quadrant you’re in. Familiar ground? Something new? You don’t need to steer anything. Just see where it goes, and when something lands, give it a moment before you move on.
