Protocol
Give the favored judgment a real devil's advocate
Challenge works only when the alternative is allowed to be serious.
When it fits
- A group is converging quickly on one recommendation and dissent has become socially expensive.
When to avoid it
- Rotate the role and preserve independent first judgments; a permanent contrarian can become predictable rather than useful.
Why it matters
After independent initial judgments, assign someone to build the strongest evidence-based case against the favored conclusion. Give them the same information and enough time to identify assumptions, counter-evidence and failure conditions. The role is to improve the judgment, not to win an argument.
Steps
- What is the favored conclusion?
- Which assumption is easiest to attack?
- What contrary evidence has been discounted?
- What alternative action becomes rational if the challenge is right?
An example
Before approving a cutover, one reviewer argues the case for delaying it using unresolved rollback, data-volume and staffing risks.
Check your result
The challenge contains evidence and a coherent alternative, not generic negativity.
Keep this limit in mind
- Rotate the role and preserve independent first judgments; a permanent contrarian can become predictable rather than useful.

Evidence and sources
Devil's Advocacy and Red Team Analysis are contrarian techniques intended to challenge a dominant view or examine a problem from a different perspective.
Adversarial challenge can become theater if the challenger lacks independence, information or a genuine alternative model.
