So. Abd and I now agree that a Bucklin system which uses just the above-median votes to break ties is probably the best first step towards median voting.


Let's stop saying it that way.


I'd be happy to. What do you propose, in 8 words or less?

A few more words, probably, particularly since you used more.

"Bucklin" is a ranked approval system, where approvals are categories into ranks in order of preference. In a modern Bucklin system, voters may categorize as many candidates in each rank as they choose, may skip ranks, and candidates not voted for explicitly are considered not approved for election. Votes are amalgamated by canvassing the first rank, checking for a majority, and then proceeding to add in the next ranked votes, in sequence, until a majority is found or the ranks are exhausted.

This system can produce a multiple majority, and a concern when this occurs is that voters may ahve over-enthusiastically added additional approvals, not realizing that they were in the majority as to their higher preference. Fear of this can discourage adding additional approvals, and thus encourage majority failure. Hence, with this proposed Bucklin variant, if a multiple majority is found, below the first rank, the votes from that rank are removed from the totals and the win is awarded to the majority-approved candidate with the most votes in the previous-canvassed rank.

(If a majority is found in the first rank, to be explicit, the win goes to the candidate with the most votes.)

However, I'm not *entirely* on board this. It violates long-standing traditions about multiple majorities. I am willing to *consider* it, under the limitation of a deterministic method. I've suggested we need more data.

Both "ties" and "median" introduce concepts which are either complex or unfamiliar.
