Four Corners

Choose this exercise

Purpose: Make visible the spread of opinion on a statement and hear the primary rationales behind differing viewpoints.

Use it when: Use when an issue has several distinct stances and the group needs to see where opinions cluster before a wider debate or review.

Skip it when: Skip when the issue requires confidential feedback or when participants lack enough context to form an opinion.

Group arrangement: Whole group divides across four corners; small groups of 2 or 3 converse within each corner.

Timing: UWT suggested 15-minute plan based on the 5 to 15 minute range in source evidence.

Materials and tools

• 4 signs labeled Strongly Agree, Agree, Disagree, Strongly Disagree (or A, B, C, D)
• Painter's tape to post signs
• Scratch paper and pen for each participant
• 1 shared digital board or polling tool for remote/hybrid use

Before participants arrive

1. Post one sign in each of the four physical corners of the room.
2. Ensure clear walking paths between all corners.
3. Display the prompt statement where everyone can read it.

Say this to open

I will read a statement. First, write your personal reaction and one supporting reason on your paper. Do not move yet. Once everyone has written a note, I will reveal the four corner options, and you will walk to the corner that best fits your view.

How to run it

1. Present prompt and write 3 minutes

   Display the prompt statement. For example: 'A complete product redesign is better than fixing current bugs.' Give participants 2 minutes of silent time to write their initial stance and one concrete reason on their scratch paper.

2. Move to chosen corner 2 minutes

   Point out the four corner labels: Strongly Agree, Agree, Disagree, Strongly Disagree. Direct participants to walk to the corner that best matches their written response. Anyone who prefers not to choose a corner may remain seated in the center as an observer.

3. Discuss in corner clusters 4 minutes

   In each corner, participants form pairs or trios. Each person shares their written reason with their small group. If only one person is in a corner, they review their notes or pair with an adjacent corner. Groups agree on one main argument to represent their corner.

4. Hear cross-corner summaries 4 minutes

   Call on one volunteer spokesperson from each occupied corner to state their group's central reason in under 45 seconds. Offer anyone the option to switch corners if hearing another perspective changed their mind.

5. Debrief and close 2 minutes

   Facilitate a brief whole-room reflection on the distribution of opinions and key tensions heard across the room.

Debrief questions

• What was the most persuasive argument you heard from a corner other than your own?
• Did seeing where people stood change your understanding of the issue?
• What common ground exists between the opposing corners?

Finished output: A visible map of group alignment on a specific statement and spoken summaries of the rationale behind each stance.

Remote

Set up a shared digital canvas with four quadrant boxes labeled with the four stances. Participants place a digital sticky note with their name or initials into their chosen box, then join assigned breakout rooms corresponding to their quadrant for 4 minutes before returning to main session.

Hybrid

In-person participants walk to the physical corners while remote participants place digital sticky notes in an online four-quadrant board projected in the room. A remote speaker and an in-person speaker take turns sharing summaries for each corner.

Access and participation choices

• Participants with mobility restrictions may point, use a handheld number card, or state their corner choice while seated comfortably.
• Anyone may choose the observer role in the center of the room and take notes on the arguments without taking a public stance.

If the session gets stuck

All participants gather in a single corner, leaving the others empty.

Acknowledge the strong consensus. Ask pairs in that corner to discuss what someone in the opposite corner would say, then invite a volunteer to voice that counter-argument.

One or two participants dominate the corner discussion.

Remind participants to break into pairs or trios within the corner and give each partner 60 seconds of uninterrupted speaking time.
