Four Corners

Purpose

Four Corners gets people out of their seats and into position. Each corner of the room represents a distinct stance, option, or answer. Participants choose their corner and then discuss with those who chose the same and with those in opposing corners. The physical movement creates energy and makes group opinion visible at a glance.

How to run

1. Label corners (1 min): Post signs in four corners of the room, each with a different option or viewpoint.
2. Pose the question (1 min): Ask a question with four possible answers.
3. Move (2 min): Participants walk to the corner that best represents their view.
4. Corner discussions (5 min): Groups in each corner discuss why they chose this position and prepare a 1-minute argument.
5. Cross-corner debate (4 min): Each corner presents. Facilitator asks clarifying questions and invites switches.
6. Debrief (2 min): What did we learn? Where is there hidden agreement?

Materials needed

• Four signs or posters for the corners
• Open floor space
• A clear question with four options

Pitfalls & common mistakes

• Options not distinct enough: If options overlap, people cluster in one corner.
• No discussion: Walking to a corner without debating the reasons wastes the method's potential.
• Forced choice: Allow a "fifth corner" (middle of the room) for genuinely undecided participants.
• Too many rounds: One or two questions per session is enough.

Inclusion & accessibility

• For mobility-impaired participants, use coloured cards they hold up instead of moving.
• Explain that it is fine to stand between corners if your view is nuanced.
• In large groups, appoint a spokesperson per corner rather than having everyone speak.

Variations

• Two Corners: Simplified binary version (agree/disagree).
• Moving Debate: After each round of arguments, allow participants to switch corners.
• Digital Four Corners: Use a poll with four options and breakout rooms per option.

When NOT to use this

• In very small groups (fewer than 8) — corners may be empty.
• When the question does not have four meaningfully different options.
• In remote settings without a strong digital alternative.
