everyone was right

How it plays

1Each team is briefed separately. Everyone else looks away.
2The briefs are not the same. Nobody is told that.
3Then one question, answered together.
4The reveal puts both briefs side by side and marks the line each team never saw.

Why it works: the argument that follows is not about judgement, it is about information, and everybody in it is being perfectly reasonable. That is what a handover failure actually feels like from the inside — which is why the people involved defend themselves so convincingly afterwards. A room that has felt this once recognises it in the wild.

Set up

Read the curtain out loud. It is the instruction that makes this work, and skipping it is the one way to break the activity.

    Give them a minute with it, then hide it before the next team looks back.

    Together

     

    Let them argue it out properly before you touch this button. The disagreement is the activity, and it will feel like a disagreement about judgement.
