Diversity-of-thought research summary
DETAILED PROCEDURE
Gather the whole group together in a circle for this activity. Explain calmly to the children: "Groups that only contain people who think alike make worse decisions. Diversity of thought is a feature, not a bug."
Step 1
Explain why: homogeneous groups have blind spots that diverse groups can see. Disagreement, when managed well, produces better outcomes.
Step 2
Group simulation: solve a complex problem with a homogeneous group, then a diverse-perspective group. Compare outcomes.
Step 3
Say gently to the children: "The most valuable voice in the room is often the one that disagrees - if the group knows how to use it."
Step 4
Practice: assign devil's advocate role to ensure disagreement is always represented.
