You're conflating the individual preferences expressed on individual ballots, and the collective preferences expressed by considering all the ballots. Each individual ballot, and each individual voters, expresses a strict preference amongst all the options that are included in the vote. However, collectively, there may be no strict preference amongst multiple options, either due to an exact tie between two options (where neither dominates the other), or due to a cycle of domination (where A dominates B, B dominates C, and C dominates A). But, under any reasonable interpretation I can see, A.6(2) only uses individual preferences to determine whether one option dominates another.

It's a similar thing to Darren's "modifying the social contract will require a 3:1 supermajority". IMO, that's the correct way to modify the social contract (and hopefully Darren, Manoj and Branden will eventually work out amongst themselves why we're not voting on how the social contract can be modified at some point), but just asserting that that's how things work, because after all the constitution didn't explicitly forbid it, seems wrong. > > Even if you change that to "more ballots strictly prefer A to B", you > > still end up with the same thing.

In maths, the term "strict" when used with comparators (especially subset, but also less than or greater than) is used to explicitly remove the equality case. If something's astrict subset of something else, they're not the same. If something's strictly less than something else, they're not the same. If something's strictly more than something else, they're not the same. Using the term without "strict" can be amiguous on that score (at least in maths), and it would clearly be bad if two tied options were to be considered to dominate each other (since both would then be removed, rather than the tie being broken by a casting vote later). So my assumption is that the term's there to remove any chance of ambiguity, not to completely change the way everything else is done. > > It doesn't say "if the ballots collectively express a strict > > preference for A over B" or something similar, which might be able to > > be reasonably interpreted how you seem to want to. > Well, it certainly doesn't make sense to treat the ballots in any sense > other than collectively -- after all, we're trying to determine their > collective impact, not their individual impact. How votes are treated collectively (that is, what they're collective preference is) is a difficult matter to fairly determine. There are dozens of ways of doing which result in different winners, all of which are "fair" in some particular sense or other. Exactly which method of interpreting a "vote" is to be used is an important matter, it's not something that should just be intuited by the vote counter. I would much rather the constitution clearly and precisely describe how the vote should be undertaken, rather than expecting the secretary to correctly judge obscure ambiguities or invent interpretations so we can get any result at all. > However, I guess I understand that you don't want to see it that way, > which leaves us with the question: now what? We should work out exactly how we want votes to happen, and we should clearly and explicitly document that in the constitution.
