CORE DEFINITION
Developed as part of the Liberating Structures repertoire by Keith McCandless and Henri Lipmanowicz, the method poses one clear question and then sequences the discussion: one minute of silent individual thought, two minutes in pairs, four minutes in groups of four, and finally a full-group share. The structure gives introverts and peripheral members a chance to form and voice a view before the loudest voices dominate. It is intended to prevent groupthink and surface contributions that ordinary discussion suppresses.
SCAFFOLDING EFFECT
Reduce cognitive load
- Sequence the discussion: move from solitary thought to pairs to fours before any plenary share. - Protect the quiet voices: let everyone form a view before the group converges. - Keep the question open: pose one clear, genuinely open question to anchor every stage.
Anchor fast decisions
Speaking in a large group requires composing a position under social pressure, which disadvantages anyone who needs time to think. The staged format lets each person form a view privately, test it with one other person, and only then speak publicly, by which point the position is already articulated. Because the earlier stages distribute airtime, the final discussion starts from many contributions rather than from the loudest one.
