One idea is reviewed four times in a row — but each pass through a single lens: what's true (facts), how it lands (feelings), what could break (risks), what it unlocks (upside). Everyone wears the same lens at the same time, so the room stops arguing positions and instead looks at the same object four different ways. **Unlike a free-for-all critique where the loudest voice wins, this sweep gives each lens its own timebox — the idea that survives all four passes is genuinely stronger, and nobody left feeling steamrolled.**

## Objectives

By the end of the activity, participants will have:

1. Seen one idea through all four lenses — facts, feelings, risks, upside — the whole room in the same lens at once.
2. Caught where a "fact" was really an unverified assumption, and marked it to check.
3. Decided with the whole picture in view, and ended on what the idea unlocks.

## When to use this activity

- A promising idea is about to be killed or loved by gut in one pass, with no even look at it.
- Your team reviews by personality — the optimist, the doubter, the accountant — and never all four at once.
- You have twenty minutes and one decision worth pressure-testing; it works on a call.

## The four lenses

| Lens | The one question | Kept honest by |
|---|---|---|
| Facts | What's actually true here — what do we know, what do we assume? | No opinions allowed this pass. |
| Feelings | How does it land — who's excited, who's uneasy, and why? | No justifying with data yet. |
| Risks | What could break, and what would we notice first? | No solving, just spotting. |
| Upside | If it works, what does it unlock that we didn't name? | No hedging with "but". |

## Setup

**Clock:** 20 minutes total — frame 1, four passes at 4 minutes each, synthesis 2.

**Space:** a wall or shared board with four labelled columns — Facts · Feelings · Risks · Upside — for one idea.

**Materials per person:**

| Item | Source |
|---|---|
| Sticky notes (one colour per lens, or one colour into four columns) | any office supply |
| A pen | bring your own |

**Materials for the room:** the four lens cards from `four-lens-sweep-prop-cards.pdf`, and the A3 poster up on the wall.

**Grouping:** 4–10 people reviewing one decision worth pressure-testing; everyone wears the same lens at the same time.

**Roles:** the room notes within each lens; you keep every pass single-lens and timeboxed and run the final synthesis.

## How to run it

| Time | Phase | Facilitator does | Participants do |
|---|---|---|---|
| 0–1 | Frame | Put one idea on the wall. State the rule: one lens at a time, everyone in sync. | Read the idea; ask clarifying questions |
| 1–5 | Facts pass | Everyone notes facts/assumptions on the idea for four minutes. Only facts. | Write facts and assumptions on sticky notes; post to the Facts column |
| 5–9 | Feelings pass | Same idea; now only reactions — where it lands and who it's for. | Write reactions; post to the Feelings column |
| 9–14 | Risks pass | Same idea; only failure points and early warnings. Don't fix them yet. | Write risks and early-warning signals; post to the Risks column |
| 14–18 | Upside pass | Same idea; only what it opens. No "buts" allowed this round. | Write unlocks and opportunities; post to the Upside column |
| 18–20 | Synthesise | Read the four sticky columns together; decide with the whole picture in view. | Discuss; decide ship / kill / reshape; name what to verify first |

## Why synchronise the lenses

Mixing lenses is how one loud doubter and one loud optimist turn a review into a tug-of-war. When the whole room is "in the risk pass," nobody is defending a position — you get four clean, complete looks at one idea.

## The card

Use the faces from `four-lens-sweep-prop-cards.pdf`: four lens cards (Facts / Feelings / Risks / Upside), a "one lens at a time" rule card, and a blank to author your own. The rule card is the load-bearing one — it's what stops the room from mixing lenses mid-pass.

## Failure modes

1. **Someone jumps lenses ("yes but the risk is…").** The room loses the single-lens discipline and reverts to argument. Rescue: "Hold it for the risk pass" — park it on the right column and move on.
2. **Facts pass turns into opinion.** People write what they believe, not what they know. Rescue: keep asking "how do we know?" until the difference between known and assumed is on the wall.
3. **It becomes a downer.** The risk pass dominates and the room forgets why the idea was promising. Rescue: the upside pass is mandatory and last on purpose — finish on what it opens, not what breaks.
4. **Synthesis collapses to a vote.** The four columns get ignored and the room just raises hands. Rescue: read one sticky from each column aloud before any vote; the picture decides, not the headcount.

## Variations

- **Remote:** four columns on a shared board; run each pass timed, everyone posting into one column before the next opens.
- **Solo prep, then team sweep:** one person does a first sweep to seed the columns, then the team re-runs it live.
- **Two ideas:** only if each keeps its own board — mixing an idea across two columns breaks the single-lens discipline.
- **Shortened (12 min):** two minutes per lens and a one-line synthesis; still finish on the upside pass.

## Facilitation notes

- The strongest moment is a fact-flag that turns out to be an assumption everyone had been treating as true.
- Keep each pass timeboxed and single-lens; the discipline is the value.
