Critique Without Killing
Productive critique, applied after divergence is complete, strengthens the idea pool rather than shrinking it. The form matters: questions ("What would have to be true for this to succeed?") preserve the idea for refinement; verdicts ("This won't work") end it.
- Klein's premortem (HBR, 2007): assume the project has already failed; generate all reasons why — identifies 30% more failure modes than forward-looking risk assessment (Mitchell et al., 1989) while legitimizing dissent before commitment
- Nemeth & Rogers (1996): devil's advocate groups generated more alternatives and made better decisions than groups without — but ONLY when the challenge targeted the idea, not the person
- Tom Kelley (IDEO, 2005): unstructured devil's advocacy "kills creativity" by providing social cover for killing ideas without accountability; the constructive version requires proposing an alternative direction after every objection
- Disney Method Critic phase (Dilts, 1994): "What's missing? What would need to be true?" — the role interrogates the plan without issuing a verdict
- Schulze-Bentrop et al. (2025, arXiv 2503.14263): AI counterarguments framed as open questions significantly enhanced process and outcome satisfaction, especially for lower-power participants
