Consensus Means Nobody Is Still Objecting

The decision rule in standards work is not majority rule, and the difference shapes everything downstream.

Most people assume committees vote and the majority wins. Standards committees generally operate on something else: consensus, which in this world is a term of art. It does not mean unanimity, and it does not mean everybody is happy. It means that the substantial objections have been worked through, that no important interest is still holding out on a matter of substance, and that the parties can live with the result even where they would have preferred something else. A dissenting participant who has been heard and answered is compatible with consensus. A dissenting participant who has been outvoted is not.

The reason for this rule follows directly from voluntariness. If you outvote a bloc of manufacturers, they will not adopt the document, and a document their competitors follow and they ignore is a fracture in the market rather than a standard. Consensus is the mechanism by which the process guarantees the thing it exists to produce. It also means a determined minority has real leverage, and that leverage is by design, because that minority may be the only party in the room who knows why the proposed approach will fail in a use case nobody else has met.

The cost is obvious and is paid every day. Consensus rewards patience, favours those who can afford to keep somebody in the process for years, and tends toward wording that everybody can read their own practice into. Ambiguity is often the price of agreement. Skilled drafters spend their careers finding formulations that are genuinely clear and genuinely acceptable to parties who wanted different things, and it is a rarer talent than technical expertise. The best standards read as though they were obvious, as though the answer had been sitting there waiting to be transcribed rather than argued into existence over years by people who began from incompatible positions. They almost never were.
