Designing collective thinking

Putting capable people in the same room does not automatically produce capable collective thinking.

What a group adds, and what it costs

Groups introduce new information and perspectives. They also introduce conformity, status effects, premature convergence, shared-information bias, production blocking, diffusion of responsibility, and social pressure.

Facilitation is therefore not merely the management of conversation.

It is the design of conditions under which a group can think.

Core questions

What a facilitator is actually deciding

  1. How should information enter the group?
  2. When should people think independently?
  3. When should perspectives interact?
  4. How should disagreement be surfaced?
  5. How should divergence become convergence?
  6. How can the group avoid mistaking consensus for correctness?
  7. What representation should hold the group’s thinking?
  8. Who decides, and under what rule?

Core principles

Six principles for a group that has to think

  • 01

    Think independently before thinking together

    Use individual reflection, brainwriting, or pre-work before open discussion where independence matters.

  • 02

    Separate divergence from evaluation

    Generating possibilities while simultaneously judging them suppresses exploration.

  • 03

    Make thinking external

    Use artefacts, diagrams, cards, maps, matrices, written propositions, and shared representations.

  • 04

    Design disagreement

    Do not rely on personality to produce challenge. Introduce procedures that legitimise alternative interpretations.

  • 05

    Change participation structure deliberately

    Pairs, small groups, silent work, plenary discussion, voting, critique, and synthesis produce different social conditions.

  • 06

    Make the decision rule explicit

    A workshop is incomplete if everyone contributed but nobody knows how the final judgement will be made.

Unsettled

What I would still argue about

The honest list. These are open in my own head, not rhetorical.

  • Under what conditions does adding more people improve a decision?
  • How should disagreement be designed rather than merely encouraged?
