Protocol
Name the decision rule when debate loops
A decision rule turns disagreement into a resolvable comparison.
When it fits
- When a team keeps presenting more arguments but no one knows what would close the debate.
When to avoid it
- Psychological safety does not mean agreement, low standards or protection from consequences. Keep respectful challenge separate from unaccountable behavior.
Why it matters
Choose the criterion, threshold, authority or experiment that will determine the choice. If stakeholders disagree on the rule, resolve that meta-decision first.
Steps
- List the competing options.
- Agree the deciding criterion or authority.
- Set the evidence threshold.
- Apply the rule consistently.
An example
The team stops debating preferred tools and agrees that recoverability and support ownership decide the pilot choice.
Check your result
The next piece of evidence can actually close the decision rather than only add another opinion.
Keep this limit in mind
- Psychological safety does not mean agreement, low standards or protection from consequences. Keep respectful challenge separate from unaccountable behavior.

Shared cognition is not identical to unanimous opinion; teams may need differentiated expertise as well as common understanding.
