Nine Whys: shared purpose
Apply in a new contextNine Whys is a conversation in pairs in which one person asks the other nine times: why is this important to you? Each answer becomes the ground for the next question, so the conversation climbs layer by layer: from what you do to why you do it. Then the roles swap, and at the end every pair shares in one sentence what surfaced. What you hear back from more than one pair is the group's shared purpose, and finding it is what the whole structure is for. Made for the start of something shared (a project, a school year, a new collaboration) and for a team that wants to know why it does what it does.
Two directions · nine whys · ± 17 min
Put it on the boardOne screen: the theme, how many whys and the time per question. No theme? The AI suggests a few for your subject. Only you see it; the class sees it only when you press Start.
This exact screen goes on your board. The timer runs per question and you stay in control: pause, add time or move on to the next step. Type the theme yourself, or with a free account the AI suggests themes for your subject or project.

Goal
the purpose behind the work
Check two things before the first run. Does A know their role? A asks, nine times, and does nothing else: no helping, no summarising, no agreeing. Say that out loud before the clock starts. And keep three minutes for the sharing at the end: without that step, nine answers stay in nine pairs.
Step-by-step instructions
4 steps
Work in pairs
Decide who is A and who is B. Give a shared theme, or let every pair take their own work.
A asks, B talks
A asks nine times “why is this important to you?”. Always ask again about the PREVIOUS answer, not about the theme again: that is where the whole structure lives.
Swap: B asks, A talks
Same question, other side. A starts at the beginning, not from B's answer.
Share with the group
One sentence per pair: which deeper purpose surfaced? What you hear back from more than one pair is the shared part.
Steps 2 and 3 are the two directions, and every why in them has its own clock; step 4 happens once, after both directions. Nine is the name of the structure: in the preparation you choose between three and twelve whys.

Students put the material in their own words and explain why it is so. Explaining forces a link with what they already know: that is understanding, not repetition. Source: Dunlosky et al. (2013), self-explanation and ‘why’ questions.

Worksheet: Nine whysPDFFor home: In your own wordsPDFWhy does this work?
Ask a group why it is working on something, and you get the polite answer: because we have to, because it is in the curriculum. Nine Whys gets past that answer. Three things do the work: every question is about the previous answer, the asker does nothing but ask, and the sharing looks for what comes back from more than one pair.
The first answer is about the task, the second about the result. Only when you ask why of that answer, and then again, does something come up that is bigger than the work itself: what someone actually cares about. That only works if every question is about the previous answer. If A keeps asking about the theme, the pair stays at the same altitude, and nine questions become nine versions of one conversation. Around the third or fourth why it usually gets uncomfortable. That is exactly where it gets interesting, so do not step in there.
A asks, nine times, and does nothing else. As soon as A starts helping, summarising or agreeing, B stops searching and starts responding to A. That is why A writes nothing down, and why it is a conversation without paper: all of A's attention goes to what B says. And that is why every why has its own clock. The class sees which question it is on, and no pair stops at the second answer because it already sounded good enough. Half-formed thoughts are fine; a short answer simply gets another why.
What a pair finds is personal. What the group finds only becomes visible when you lay the pairs side by side: one sentence per pair, and then the question of what came back. What you hear two or three times is the shared purpose, and it is worth more than anything you would make of it yourself. That is why the sharing is the step the rest exists for, and why it gets three minutes instead of half a minute.
When it fits, when to pick something else
When it fits
- At the start of a project or a collaboration. Before a group divides up who does what, it finds out why the work is worth doing. That answer comes back later, when the project gets stuck.
- When the group agrees on what, but not on why. Everyone wants the school newspaper, but one for the fun of it, another for their CV and a third to have something to say. Nine Whys puts those differences on the table, and often what is shared underneath them as well.
- For careers guidance and choices. Why does this direction draw you? Without a shared theme everyone takes the direction they are considering, and the answers get more personal than with one theme for the whole class.
- With a team, at the start of a school year. "Why do we teach this subject?" in a department, or "why are we doing this project?" on a staff training day. The sharing at the end lets the team hear what it shares.
- Before a decision. A group that knows why it wants something finds it easier to choose between two plans. Put the shared purpose on the board, and afterwards hold the choice up against it.
When to pick something else
- When you are looking for the cause of a problem. Nine Whys climbs towards a purpose; it does not dig for a cause. If you want to know why something goes wrong, take Five Whys: the same ladder, the other way.
- When personal answers do not feel safe yet. Nine times "why is this important to you?" gets close to what drives someone. In a group where that still feels risky, you get nine polite answers. Then choose a theme about the shared work instead of about the person, and say beforehand that in the sharing each pair shares only the one sentence it chooses itself.
- When you want a decision or a list of ideas out of it. The structure makes the why visible; it decides nothing and produces no list. Use the purpose that surfaced as the yardstick, and then gather the ideas for the choice with Snowball (1-2-4-All).

Frequently asked questions
What exactly is Nine Whys?
A structure for pairs to find the purpose behind shared work. A asks B nine times "why is this important to you?", each time about the answer B has just given. Then the roles swap: B asks, A talks, and A starts again at the beginning. At the end every pair says in one sentence which deeper purpose surfaced. What comes back from more than one pair is what the group shares. It is one of the Liberating Structures, and the name comes from there.
How long does Nine Whys take?
With the default settings the whole structure takes ± 17 minutes: 2 rounds, briefing and look-back included.
With the default settings about seventeen minutes. Each direction starts with forty-five seconds to take the roles, followed by nine questions of thirty seconds: just over five minutes per direction, ten and a half for both. The sharing at the end takes three minutes. That is thirteen and a half minutes of steps; the preparation adds a minute for forming the pairs and two minutes of reflection at the end. With seven whys it takes about fifteen minutes, with twelve about twenty. You set the roles, the questions and the sharing yourself, each in steps of fifteen seconds (one setting covers all the whys), and the player moves on to the next question by itself.
Does it really have to be nine times?
No. Nine is the name of the structure, and in the preparation you choose between three and twelve. In a short lesson seven questions work too; the question stays the same. Do count on the first answers almost always being about the task and the result, and on the interesting part only starting once those run out. With far fewer than five questions you often stop right at that point.
What if the answers run out after three whys?
That is the moment the whole structure hinges on. Around the third or fourth why it usually gets uncomfortable: the obvious answer has run out, and something more genuine has to come. Do not step in there. A short answer simply gets another why, and "I don't know" is fine too: then A waits a moment and asks the same question again. Half-formed thoughts count. What A does not do is finish the answer for B.
How do you choose a good theme?
A good theme is something the pairs actually work on or deal with themselves, not an abstract concept: "our project about the neighbourhood", "the school play", "why we teach this subject", not "sustainability" or "democracy". It stays on the screen for the whole structure, the same in both directions. You can also leave the field empty; then every pair takes their own work, and that is not a lesser version. No theme in mind? Choose "AI writes them" in the preparation: you get a few possible themes for your subject or project and tap one. If you prefer your own assistant, such as Microsoft Copilot, copy the request from the same screen.
Why does nobody write anything down?
Because it is a conversation, and because A's attention has to be on B. Anyone who is writing is only half listening, and an asker who takes notes starts summarising instead of asking further. Only one sentence needs keeping: the purpose that surfaced, and the pair says it out loud in the sharing. If you want to make those sentences visible, have them written on a sticky note at the end.
What happens in the sharing?
The pairs have finished both directions. Every pair says in one sentence which deeper purpose surfaced: the purpose, not the whole conversation. You listen for what comes back from more than one pair, and then ask the group what it heard. What you hear twice is the shared purpose. It is the harvest of the structure, and that is why this step takes three minutes and not thirty seconds.
How is it different from Five Whys?
The same ladder, the other way. Five Whys digs down, to the cause of a problem: why does this happen? The pair writes the chain together on one sheet. Nine Whys climbs up, to a purpose: why is this important to you? One asks, the other talks, and nothing is written down. Looking for a cause, take Five Whys; looking for what drives people, take Nine Whys.
How do you facilitate Nine Whys?
Beforehand: choose a theme or leave the field empty, and say out loud what A's role is: asking, nine times, and nothing else. Model it once if you like. During the questions: walk around without stepping in, especially around the third or fourth why, when it goes quiet. At the swap: remind the class that the new conversation starts at the beginning. In the sharing: one sentence per pair, and listen for what comes back; then ask the group what it heard, instead of drawing the conclusion yourself.
Is Nine Whys a Liberating Structure?
Yes. Nine Whys is one of the Liberating Structures by Henri Lipmanowicz and Keith McCandless: short structures with tight steps, in which everyone takes part instead of only the fastest speaker. The LudensFlow version keeps the question, the swap of roles and the sharing with the group, and turns it into a classroom structure: every why is its own step with its own clock, so the class sees which question it is on. What drops out: the minute in which everyone first writes down on their own what they do, the short title the asker notes for the other's purpose, and the in-between round in fours. Here nothing is written down, and the pairs share straight away with the whole group.
Finding the why together: which structure fits?
| Structure | Goal | Group | Duration | When it fits |
|---|---|---|---|---|
| Nine Whys | find the purpose behind the work | pairs | ± 17 min | the group disagrees about why |
| Five Whys | get to the cause of one problem | pairs | ± 11 min | a problem that keeps coming back |
| Interview in Three Rounds | interview each other and report back | fours | ± 12 min | making listening happen in a fixed four |
| Inner & Outer Circle | the same question with a different partner each time | whole class | ± 13 min | open questions, speaking time for everyone |
| Conversation Café | talk calmly about something complex | 4–8 | ± 35 min | understanding needed, not a decision |
| Snowball (1-2-4-All) | funnel ideas from individual to plenary | 8–32 | ± 18 min | after the purpose: the ideas |
