There are times when consensus makes sense:
- A time standard - the atomic clock - is agreed to be the "official" time.
- The French - who invented it - define SI - the international system (better known in America as Metric Measurement).
- Pantone sets the standard for color, and all other methods of identifying color agree to follow its color shadings standard.
- If there is disagreement in a family about where to go on vacation, they may decide to vote, and accept the consensus of the majority. They might agree, by consensus, to cede that decision to a single person.
