Devil's Advocate
Assign someone to argue against the preferred option.
Explanation
Groups naturally converge on solutions too quickly because everyone wants to get along and make progress. By formally assigning someone to challenge the group's thinking, you force consideration of alternatives and potential problems. This role should rotate so no one becomes the permanent 'negative' person.
Real-World Example
Team wants to launch in December: Devil's advocate argues it's too close to holidays, customers won't be paying attention, support team will be understaffed. This surfaces real concerns that need addressing, even if December launch still happens. Board meeting: one member always asks 'What could go wrong with this strategy?'
How to Apply
In important meetings, assign this role explicitly: 'Sarah, please argue against this proposal.' Rotate the role to maintain relationships. Reward good devil's advocacy with recognition. Create psychological safety—people shouldn't fear backlash for raising concerns. Make it about improving the idea, not killing it.
